　　Zhang Jun first highly praised the broadcast effect of "Guarding Tomorrow" in the second season. He pointed out that "Guarding Tomorrow" is a concrete manifestation that the state media and judicial organs jointly shoulder the responsibility of protecting minors. Zhang Jun also stressed at the meeting: in the protection of minors, family, school, society and judicial protection are indispensable. Among them, family protection is the foundation, school protection is the key, social protection is the support and judicial protection is the guarantee. In the new era, the CPC Central Committee with the Supreme Leader as the core has put forward new and higher requirements for the protection of minors. After the amendments to the Law on the Protection of Minors and the Law on the Prevention of Juvenile Delinquency, which were just concluded at the 14th session of the 13th the National People’s Congress Standing Committee (NPCSC), it will certainly provide more powerful support for the protection of minors and crime prevention.

　　Since the first season of 2017, "Guarding Tomorrow" has become a brand TV program in the field of minors’ protection, and it has also witnessed the unremitting efforts and outstanding achievements made by the procuratorial system to protect the legitimate rights and interests of minors. The third season of "Guarding Tomorrow", which is about to meet the public, continues to respond to public concerns, focusing on the most cutting-edge and most concerned judicial protection of minors, shocking criminal acts against minors and making a voice for protecting children!

　　After eight months of case screening, program planning and filming in 11 provinces and cities, with the help of 13 outstanding prosecutors and authoritative experts in juvenile justice, family education and children’s psychology in China, the third season of "Guarding Tomorrow" will meet the public. From school bullying, a hot topic in the society, to parenting education that parents are widely concerned about, and juvenile drug-related and economic crimes that have gradually become hot spots, this season’s "Guarding Tomorrow" continues to use the most plain and vivid narration to popularize and explain the law for underage audiences and their parents, and puts forward suggestions and opinions to functional departments.

　　The third season of "Guarding Tomorrow" not only discusses the case from the legal, psychological and media perspectives, but also deeply analyzes the case from the perspective of social development and national legislation, calling for the continuous improvement of the system and laws to better promote the judicial protection of minors in the whole society.

In today’s complicated star world, the name Zhao Lusi once lit up the eyes of countless young people like the morning light. Her "new face" has caused countless discussions and still occupies a place in the hot search. Although her appearance is constantly changing, we have to reflect: Is her transformation to cater to the traffic market or to improve self-worth? This paper will deeply analyze the growth and transformation of Zhao Lusi, from her early experience to the turning point of her career, and gradually reveal how she found a balance between pop culture and self-identity.

Early experience: the interweaving of dreams and reality

Zhao Lusi’s early experience can be described as tenacity and hard work. She was born in Chongqing in 1998. As an only child, she grew up under the care of her parents. Since childhood, Zhao Lusi has shown a strong interest in performance. Although her parents are ordinary workers, their support and encouragement have become an important driving force for Zhao Lusi to embark on the road of performing arts. In order to pursue her dream, she began to participate in various talent competitions in high school. Although her popularity was not high at that time, she never gave up her vision of acting career.

In college, Zhao Lusi entered the art and media major of Chongqing University. Here, she not only strengthened her acting skills, but also made many friends who pursued her dreams like her. This period of time is not only the process of her continuous learning and growth, but also her exploration and reflection on her future career.

The rise of career

Zhao Lusi’s career began in 2016. She played a supporting role in the online drama go princess go. Although she was an unknown little role, her performance left a deep impression on the audience. Subsequently, her role in the TV series "Wei Baobao" attracted more attention. Her sweet appearance and natural and unpretentious acting skills won the audience’s love, and Zhao Lusi’s image of "sweet girl" took root in the audience’s heart.

Since then, her career has developed rapidly, especially her outstanding performance in the popular TV series "Three Thousand Crows Kill" and "Rumored Chen Qianqian", which made her gradually move from "ordinary girl" to the ranks of popular florets. The audience’s expectations for her are constantly improving. However, in this process, she also faces a lot of pressure.

Challenges and disputes in the period of transformation

With the promotion of popularity, Zhao Lusi also began to face the challenge of public opinion. Recently, she has been widely discussed because of the change of her face value, and some even commented that she is "less and less like herself". In this era dominated by traffic and face value, the transformation of Zhao Lusi has triggered heated discussions and debates among netizens. On the one hand, her efforts and self-discipline make her grow under pressure; On the other hand, in the face of external evaluation, she is inevitably confused and lost.

In a live broadcast, Zhao Lusi confessed his mental journey: "Everyone wants to be better, but I will lose myself from time to time and can only try my best to stay true." It was this speech that made her fans see a real and fragile situation and made people around her re-examine her decisions and choices.

An important turning point: remolding self-worth

Just when everyone thought that Zhao Lusi would continue to cater to the expectations of the outside world and go down the road of high value and little sweet girl, she made a shocking choice-she decided to transform from a "sweet girl" to a more mature actress. This choice has aroused great repercussions, and many comments have said that it will be a major turning point in her career. In this regard, Zhao Lusi said in an interview: "I hope that my acting skills can grow up with my appearance changes and truly not be labeled."

This statement is undoubtedly a thoughtful consideration of her career planning, indicating that she is more eager to break the definition of her through her works and acting skills. During this period, Zhao Lusi constantly tried different roles and challenged her acting boundaries. She played more complicated and challenging roles in many new plays to show her diversity and progress. This change not only enriches her acting career, but also constantly shapes her public image.

Public evaluation and external influence

In recent years, Zhao Lusi’s identity in the entertainment circle has gradually changed, and people are constantly trying to label and define her. In this regard, she once said: "Everyone has their own growth process and changes, and external evaluation is inevitable, but I hope that my own truth can be understood." This made many of her supporters feel the same way and expressed their support for her transformation on social media.

At the same time, Zhao Lusi’s commercial operation has also attracted widespread attention. Some skin care brands she endorsed, especially domestic brands that are easy for the public to accept, show her business acumen and social responsibility. By choosing a brand with social influence, her image has gradually transformed from a simple flow flower to a public figure with more depth and connotation.

Summary and Enlightenment: The Importance of Self-cognition

Zhao Lusi’s growth story tells us that when facing the pressure and expectation of the external environment, the importance of maintaining self-awareness and values cannot be ignored. In this unpredictable and competitive entertainment circle, everyone may lose themselves in the rapid changes. However, it is her persistence and pursuit of self-worth that makes Zhao Lusi stand out from many artists and become a role model for young people.

In the future, she will continue to face challenges from all sides, but no matter how the outside world changes, her heart will always be firm. As she said, "I hope to show you the real me with my works, not me defined by external labels." In the journey of pursuing dreams and realizing values, Zhao Lusi is undoubtedly an inspiring existence.

Editor in charge:

When the golden age of metropolis daily has passed, and now it is faced with the huge impact of new media, do metropolis daily people cling to the remnants and cling to the shortcomings, or do they keep pace with the times and admit the new? This is indeed a problem. I have been immersed in the paper media for nearly 20 years. My attitude is that we must jump out of the thinking limitations of the paper media, abandon our sense of superiority and make some necessary and even painful changes, which may lead us out of the predicament.

First, can it be "value reconstruction"?

Zhang Jinhai, a professor at the School of Journalism, Wuhan University, pointed out that the rise of new media and the decrease of the value of traditional media is a fact, but it does not mean that it will inevitably die out, and it can be reborn through "reconstructing value". That is to say, traditional media can use the quality of information to counter the information quantity of new media, realize value reconstruction, transfer the information quantity to new media, and focus on the quality of information. His formulation is novel and practical. But he only mentioned the transfer of "quantity", not the transfer of "speed". I think two transfers can be made.

The first is the transfer of information "quantity"

Running a thick newspaper with rich content and information was once the basic requirement of readers’ market for newspapers, and it was also the pride of urban newspapers. However, in the Internet era, this situation has undergone fundamental changes. No matter how many pages a newspaper has, no matter how thick it is, it can’t be compared with the massive information on the Internet. In addition, the distribution cost is upside down, and thick newspapers are obviously out of date or overreaching in the Internet age.

Therefore, at present, we should firmly establish the concept of "don’t fight for mass and fight for quality", transfer the amount of information to online media without hesitation, work hard on the quality of information, make the thick newspaper "thin" and the content "thick" ① (see the end of the article for references with digital subtitles. The same below). Through careful screening and editing, useful and quality information will be provided to readers, so that readers can spend the least time to see the information they want to see and need to see most.

At the same time of "thinning", we can also consider "thinning", that is, dividing it into different stacks, packaging it into volumes and selling it separately. Readers can choose to buy according to their own needs, without spending more money on a lot of things that they are not interested in at all. Readers who want to know about financial news can buy financial stacks, those who want to watch entertainment fashion news can buy entertainment stacks, and those who like social news can buy social stacks, which not only saves newspaper printing costs and distribution costs, but also saves readers’ reading time and audience’s attention.

The second is the "fast" transfer of information.

Like the mass content of information, the paper media can’t compete with the new media in the instant dissemination of information, but it can show our advantages in accuracy, authority and effectiveness.

With the rise of new media, especially social media, the information speed is beyond people’s imagination. Facebook has 800 million users worldwide, while Twitter has 150 million users, generating 1,000 Weibo messages every second, and users post more than 200 million Weibo messages every day. Sina Weibo can also produce 100 million pieces of content every day during peak hours.

Since the media era, everyone is a reporter. Although we have the largest editorial team in Anhui, you can’t be greater than the number of people from the media. They are always at the scene of the event, and they can publish what they have seen and heard to various new media platforms at any time. In the rapid release, we must admit that we can’t compete with new media.

However, we don’t fight for "fast" with online new media, which doesn’t mean that we are indifferent to this information. Instead, we should pay attention to and collect important information of online media in time, and use it as an information source to "deepen" and "sublimate" new media information through questioning, combing and supplementing, and in-depth interpretation, so as to change fragmented information on the Internet into complete information and "fast reading" on the Internet into "slow reading" of newspapers.

I’m not afraid of the new media express first, but I’m afraid of simply following behind to make the printed version of online media. Traditional media should organize fast and messy information fragments organically through "anti-fragmentation" operation, and after studying the content and direction of new media, set a new agenda to produce newer, more complete, more accurate and more valuable content than online media.

Second, can you "interact"?

The biggest advantage of social media is interactivity, but can’t paper media overcome the problem of poor interactivity? The answer is no.

First, strengthen the interaction of newspaper layout content.

Although almost all city newspapers now have "hotline news" or "interactive news" pages, the interactive consciousness of newspaper editors is still not optimistic. I specially checked all the evening newspapers and metropolis newspapers in Anhui, and found that there was no contact information of the editor or editorial department on the page. Then I would like to ask, readers have ideas, opinions and even new content to feedback about the information content published in your layout. Who do they talk to?

In this respect, some well-known metropolitan newspapers in China have done a good job. Every page of Xinmin Evening News and Dahe Daily has an editor’s mailbox, while Yangcheng Evening News and yanzhao metropolis daily have a department’s mailbox, while Yangzi Evening News has an editor’s mailbox and a department’s telephone number. Although this is a trivial matter and a detail, it reflects the interactive consciousness of a newspaper.

Today’s readers won’t read whatever you publish, as in the past. They have a strong desire to communicate and express, that is, to discuss and question under the news. Therefore, the interactivity of a newspaper can not only be reflected in one or two hotline news pages or interactive news pages, but should permeate every page, topic and even every important manuscript of the newspaper.

As someone said, in the all-media era, the newspaper can’t be signed and delivered for printing, and the reporter’s editing work is finished. Because our news articles may be being discussed on the Internet, if we don’t pay attention to and collect readers’ reactions and give feedback in the next day’s report in time, we will lose the opportunity to interact with readers.

The second is to provide an interactive platform for readers through activities.

The world’s best-selling newspaper, Japan’s Yomiuri Shimbun, has many secrets of success, one of which is the concept of "social newspaper". They organize various activities through newspapers to enhance readers’ interaction and experience and realize the "social" role. They organize as many as four or five hundred social promotion activities every year, the most influential of which is to invite six Nobel Prize winners to give speeches in Japan every year, which is not only welcomed by readers, but also becomes their service brand.

Many magazines are ahead of newspapers in this respect. There is a magazine called Entrepreneur in China. They are not just running a magazine, but using their own resource advantages, they have run dark horse races, dark horse clubs, young angels clubs and other products to provide services for entrepreneurs.

It’s time to set up a new concept of running a newspaper. Newspapers should not only be static news release machines, but also organize as many brand planning activities as possible, which have both social and economic benefits, and are both applauded and sold. In the new media environment, organizing social activities may be more important and urgent than simply releasing news.

The third is to realize cross-border interaction through social media.

When Weibo and other social media just emerged, they once made some traditional media people nervous, and some media even prohibited newspaper reporters from editing and publishing information in Weibo.

In fact, social media, as a new channel and platform for news dissemination, is the general trend, and it is impossible or ridiculous to restrict and prohibit media and media people from using social media. At present, almost all domestic paper media may have opened official Weibo on Sina and Tencent Weibo.

According to the 2012 Sina Media Weibo Report released by public opinion monitoring Office of People’s Daily Online, by the end of 2012, the total number of media Weibo certified by Sina Weibo had exceeded 110,000, including 17,221 media official Weibo and 92,945 media practitioners Weibo.
No socializing, no media. Metropolis Daily must be good at using social media to build its own cross-border interactive platform. The Weibo fans of Xin ‘an Evening News, Sina and Tencent, have now exceeded 800,000. It is necessary for us to study how to operate our content on the Weibo platform, give play to cross-border interaction and make up for the lack of timeliness and interactivity of newspapers.

Southern Network News (all-media reporter/Ou Yaqin) endured the high temperature and traveled long distances. Recently, the "most beautiful angel volunteer service team" composed of 22 medical staff from Dongguan went to Shaoguan for a five-day medical assistance activity, which was "sought after" by local residents. The reporter learned from the Dongguan Municipal Health and Family Planning Bureau that in recent years, six 3A hospitals in Dongguan have helped 15 hospitals in Shaoguan. In 2016, 88 medical staff were dispatched, and in 2017, 92 medical staff were dispatched. With the improvement of medical professional technology, talent management and donated equipment, Dongguan not only helps local people enjoy better medical services, but also effectively improves the medical technical service level of recipient hospitals.

　　More than 1,500 patients were served in three free clinics.

　　At 11: 40 on May 26th, at the entrance of Renhua County People’s Hospital in Shaoguan City, the temperature has risen to 33 degrees. Twenty-two medical staff from Dongguan sat in temporary tents and patiently treated patients. In a sweat, they treated more than 400 patients.

　　This is the last stop of the "most beautiful angel volunteer service team" composed of 22 Dongguan medical staff to Shaoguan medical assistance activities. The reporter learned that from May 23 to 27, during five days, the service team came to Shaoguan Lechang Second People’s Hospital, Nanxiong Traditional Chinese Medicine Hospital and Renhua County People’s Hospital for help.

　　Among these 22 medical staff, they are all drawn from the two sessions of "The Most Beautiful Medical Care in Dongguan", covering major medical disciplines, such as ICU, endocrinology, surgery, gynecology, obstetrics, pediatrics, B-ultrasound, anesthesiology, general practice, etc., and helping to serve local residents and hospitals through free clinics, rounds and academic lectures.

　　"The academic lecture is in the special form of’ point class’, and everyone has prepared courseware. What the local doctors like is just like ordering food, so let’s go up and talk about it." Wang Sangui, the captain of the "Most Beautiful Angel Volunteer Service Team" and vice president of Nancheng Hospital, said that in the exchange, the medical colleagues in Shaoguan are most interested in pediatrics. In addition, because the local government is preparing for the marathon, Dr. Cai Lihua from Dongguan People’s Hospital is surrounded.

　　The arrival of the service team was sought after by local residents. The reporter learned that in order to see the experts, many residents arrived at the free clinic by car for 1 or 2 hours on the same day after learning the activity information. Dr. Liu Guojun from Dongguan Children’s Hospital can’t leave until half an hour after the end of the free clinic, and he can’t even take a sip of water.

　　According to statistics, in the three free clinics held in three cities, the whole service team received more than 1500 patients.

　　Helping action blows the "assembly number" of medical care

　　The 22 medical staff are the business backbones of major hospitals, and they can spend a whole week in Shaoguan during their busy work, all for the same goal.

　　"Most of them hold important positions in their respective units, and they are top talents in various specialized fields. They are the elite backbones of hospitals in Dongguan. Many of them are department directors, and they are busy with their work. For this action, some of them gave up the original arrangement to go home to visit relatives, some gave up the opportunity to exchange and study in other places, and some of them immediately rushed to Huizhou to participate in official activities after attending the free clinic." Song Hongnan, deputy researcher of Dongguan Health and Family Planning Bureau, said, "For the health of Shaoguan people, the most beautiful angel volunteer service.

　　Due to the tight time and heavy workload, the members of the service team helped during the day and traveled at night without stopping. For example, from Lechang City to Nanxiong City, the journey is more than 100 kilometers, and it took more than two hours. After arriving, it was already over 9 o’clock in the evening. Simply eat and rest, and early the next morning, members of the service team have appeared at the free clinic.

　　After several days of high temperature, the service team members put on white coats and brought all the free clinic tools, but even if the fan was turned on to the maximum wind, it could not stop the rolling sweat. "After half a day, it’s almost like steaming a sauna." The players laughed and said that they had lost several pounds in the past few days.

　　Even though sweating profusely, under the scorching sun, the doctors insisted on treating all patients seriously. From inquiry, examination, diagnosis, prescription writing to doctor’s advice, every link should be careful. In Lechang Free Clinic, Dr. Wang Sangui patiently analyzed the condition of a cancer patient for more than 20 minutes. Therefore, although the daily free clinic was originally scheduled for one and a half hours, it actually lasted for nearly three hours until the last patient left with satisfaction.

　　It is the trust of Shaoguan people that keeps the members of the service team persistent. A patient came to consult because of gynecological problems. Some minor conditions of the operation made her panic. Director Zhong Xiangzhen of Dongguan Fifth People’s Hospital systematically analyzed the symptoms for her and made suggestions to convince her. "The big expert from Dongguan, you are right, I will cooperate with the treatment well!"

　　"Our doctors Zhang Xiuwei, Huang Shuling, Wei Li, Liu Hanhai and Zou Yicheng have too many similar stories. In short, all medical staff have been warmly welcomed by local patients and medical staff." Wang Sangui, the captain of the service team, told reporters that it is the best praise for the team members to see the patients who participated in the free clinic leave with satisfaction.

　　We will focus on improving Shaoguan’s maternal and child health care and Chinese medicine service capabilities

　　This assistance action is only a microcosm of Dongguan’s precise assistance to Shaoguan’s medical and health care in recent years.

　　According to statistics, so far, six 3A hospitals in Dongguan have helped 15 hospitals in Shaoguan, sending 88 medical staff in 2016 and 92 medical staff in 2017. Through the assistance of medical expertise, talent management and donated equipment, the medical technical service level of Shaoguan recipient hospitals has been improved, and the local people have also enjoyed high-quality medical services.

　　"More than 200 operations were performed in a year, and one person promoted the improvement of the whole department and even the hospital, and also made us have two breakthroughs." In Nanxiong Chinese Medicine Hospital, the relevant person in charge specially praised the Dongguan doctor. He said that in March 2017, Dongguan Hospital of Traditional Chinese Medicine sent Zhang Binshan, deputy chief physician, to support the local medicine for one year, focusing on helping the construction of the Department of Orthopaedics of Traditional Chinese Medicine in the attached hospital. In a short period of one year, driven by Zhang Binshan, Nanxiong Hospital of Traditional Chinese Medicine has established provincial-level scientific research projects and built two provincial-level specialty colleges, which is self-evident.

　　Therefore, Jiao Xiaosong, vice mayor of Nanxiong City, compared the role of doctors in Dongguan to "hematopoietic stem cells" and thanked them for improving the health level of 480,000 people in Nanxiong.

　　"What Shaoguan needs and what Dongguan can do", on the afternoon of May 25th, Ye Xiangyang, director of the Dongguan Municipal Health and Family Planning Bureau, also specially came to the site of the free clinic of Nanxiong Chinese Medicine Hospital. After learning about the great changes that Zhang Binshan has brought to the hospital, he also cocked his thumb. He said that the arrival of the "most beautiful angel volunteer service team" on the one hand is to implement the policy of counterpart assistance between Dongguan and Shaoguan, and promote the improvement of the level of the two places. On the other hand, the service team also brought Dongguan’s medical ethics, medical technology and mental outlook to Shaoguan, showing the "most beautiful side" of Dongguan medical care.

　　According to reports, this year, the Dongguan Municipal Health and Family Planning Bureau will also focus on promoting various counterpart support to help Shaoguan. Including the promotion of Shaoguan-related medical staff to Dongguan for clinical, auxiliary examination and other specialized study and training, focusing on improving the training and assistance of maternal and child health care and Chinese medicine service capabilities; Send a medical team to Shaoguan to carry out academic exchange and management experience teaching; Carry out equipment assistance and hardware facilities to help guide the work.

With the popularity of the automobile industry, especially as an urban sports vehicle, many TXTs who don’t understand cars think that the SUV with four-wheel drive system is an off-road vehicle, which is completely wrong.

1. -（||）

Off-road performance: Jimny has a good reputation in the off-road circle. Its powerful off-road performance makes it occupy a place in the list of off-road vehicles at home and abroad. Someone once said: "Where Lu Xun can go, Jimny can also go;" Where Lu Xun can’t go, Jimny can also go. " You can imagine how powerful Jimny’s off-road performance is! Short axis, minimum ground clearance of 190mm, approach angle of 37, passing angle of 31 and departure angle of 46, these inherent advantages give Jimny strong off-road performance. The front and rear integral axles and non-loaded body make Jimny have strong chassis rigidity. Jimny is equipped with part-time 4WD system, which can switch freely between 2WD (two-wheel drive), 4wd (four-wheel drive) and 4WD-L (low-speed four-wheel drive). In the low-speed four-wheel drive mode, the output torque of the transmission shaft will be amplified by 2.6 times to cope with Jimny’s limit of 110Nm. Although Jimny has strong cross-country performance, he also has serious injuries. Its front and rear axles adopt open differential, which leads to uneven power distribution when the wheels slip and weakens the ability to get out of trouble. Of course, for cross-country enthusiasts with strong hands-on ability, this is not a problem, and it is inevitable to move the knife on the differential.

Three SUV models,

Off-road performance: Isuzu is a very niche brand in China. Many people have never even heard of it. Compared with Wuling, its reputation is far worse. However, this does not prevent it from having a strong off-road capability. The minimum ground clearance of Isuzu is 225mm, that of approach angle is 26, and the departure angle is 21. There are no shortcomings in the body data. Because it is a hard-core off-road vehicle with a non-load-bearing body, Isuzu mu-X adopts a front double wishbone independent suspension, and the rear whole axle is an independent suspension. The four-wheel drive system adopts part-time 4wd, and both front and rear axles are open differentials. There are 2H (two-wheel drive), 4H (high-speed four-wheel drive) and 4L (low-speed four-wheel drive) modes. Magnify the torque by 2.48 times. In addition, Isuzu mu-X adopts diesel engines, including 2.5T and 3.0T diesel turbocharged engines, in which the maximum power of 2.5T model is 136Ps and the maximum torque is 320Nm, and the maximum power of 3.0T model is 177Ps and the maximum torque is 380Nm, which is very impressive, greatly enhancing the ability to get rid of difficulties.

Da was born in a famous family, under the banner of Little Rabbit Music, and once it was launched, it sucked countless powders. It is not an exaggeration to say that it has ignited the hard-core SUV market. In fact, Toda originated from Nissan’s Navara platform. Navara is a car with less power than Tourer, but as an off-road vehicle, there is no problem in making it durable. As a hard-core SUV that focuses on off-road performance, a non-loaded body is a must, and there is no problem with part-time four-wheel drive. The low-level four-state torque is amplified by 2.7 times. That sounds great, right? More importantly, in addition to the central transfer box, Tuda is also equipped with a rear axle. The claw differential lock is equivalent to the middle and rear two locks, and its ability to get out of trouble is beyond doubt. If you really want to drive a Tuda to play cross-country, you can basically switch to a capable AT tire or MT tire, and most of the situations can be solved.

4、H5

The most pragmatic hard-core off-road SUV of Haval brand belongs to Haval H5, but it is too big to cover, but in terms of off-road, Haval H5 is quite good. It is equipped with a 2.0T gasoline/diesel engine, in which only the maximum torque of the engine reaches 320Nm. Among them, the manual transmission model has part-time 4wd, and with Eaton’s mechanical differential lock, the torque can be amplified by more than 2 times. Coupled with the automatic transmission model with higher configuration and higher comfort, Haval H5 is definitely worthy of the title of "God Car".

Off-road performance: If you only look at the appearance of the X8, you may think that it is an ordinary urban SUV. If you think so, then you underestimate it. The minimum ground clearance of landwind X8 is 200mm, that of approach angle is 27.4, and the departure angle is 24.2, which is far better than that of urban SUV. Moreover, the Landwind X8 also uses a non-loaded body, which is also a major criterion to judge whether it is a hard-core off-road vehicle. Landwind X8 also comes standard with a set of standard part-time 4wd system, with 2WD (two-wheel drive), 4H (high-speed four-wheel drive) and 4L (low-speed four-wheel drive) modes. The center differential has a 50:50 front and rear power distribution. The transfer case is equipped with a torque amplifying gear with the amplification ratio of 2:1, and the rear axle adopts Eaton differential lock, which has the ability to limit the slip between wheels and greatly improve the performance of getting out of trouble.

Off-road performance: paladin is an old-fashioned hard-core off-road vehicle. Why is it called costume? Because it hasn’t been changed in China for nearly 10 years, it seems to have been forgotten by Nissan. However, paladin’s off-road performance and reliability are beyond doubt. In 2004, China driver Lu Ningjun successfully completed the Dakar Rally in a simple modified paladin, which proved that this car was very trustworthy to some extent. Paladin’s four-wheel drive models are equipped with the traditional part-time 4wd system. The power of the engine is transferred to the transfer box through the gearbox. When the transfer box is in the four-wheel drive position, the front and rear axles of the vehicle are hard connected with torque amplification gears, and the magnification is about 2 times. However, paladin’s four-wheel drive system does not have a central differential, so the four-wheel drive state cannot be used on paved roads. Moreover, Shengdu on sale is not equipped with any anti-skid device between wheels, which directly limits its ability to get out of trouble.

The Dream of China, starring Liu Yifei, Chen Xiao, Joe, Ada and Jelly Lin, has been very popular recently, and its popularity continues to rise. Meng Hua Lu was adapted from Guan Hanqing’s zaju script Zhao Paner’s romantic rescue.

The background of the story takes place in the Song Dynasty, and the costumes in the play are extremely excellent and elegant, vividly and skillfully highlighting the personality characteristics of the characters. No matter the actors, themes, costumes and plots are excellent, the actress’s shots in this film are even more exquisite and praised by the audience. Of course, all this is indispensable to the credit of lens language design.

Meng Hua Lu has made great efforts in the design and expression of lens language, showing the scenes and characters vividly. The shooting of the whole film is very skillful, and the lens language and picture are very beautiful, artistic, full of meaning and endless charm, presenting pleasing visual effects and bringing excellent visual experience to the audience.

The lineup of Meng Hua Lu is luxurious. The photography director is Yiqin, a senior photographer from Taiwan, China. Director Yang Yang is a famous female directors in China, a national first-class director, and his works have won various awards. The two men joined forces to integrate the theme of the film and the expression of characters’ emotions into the lens language, so that the quality and standard of Dream of China by going up one flight of stairs presented an excellent work to the audience.

In the beginning, Zhao Paner came slowly with a row of bamboo rafts in the distance, his hands alternately swaying bamboo paddles, the breeze blowing gently, the lake waves rippling, and a peaceful and pleasant scene of Jiangnan water town jumped from the paper, giving people an immersive feeling. "arm in arm to punt, the beautiful lake swings."

The camera will play Liu Yifei, the "fairy sister" of Zhao Paner. It is gentle but smart, elegant but atmospheric. This clip has made many viewers watch it again and again, immersed in enjoying this unique beauty like a fairy.

In the fifth episode of the play, the man and the woman talked about drinking, and the wine strength came up, and the eyes looking at each other also changed. Camera switching, a moment to Zhao Paner, I saw her chin staring, charming eyes, a moment to Gu Qianfan, I saw him staring, eyes tender, cut to two people in the same frame, the two sides stared at each other, rendering a subtle atmosphere, at this time, the psychological activities and relations between the two people, can be said to be self-evident.

When parting, the camera switches back and forth between the two. Zhao Paner stood on the small building, Gu Qianfan sat on the boat, and their eyes were reluctant and thoughtful. Zhao Paner eyes flow, tenderness, never removed from Qian Fan, always looked at the boat.

In the face of Zhao Paner’s eyes, Gu Qianfan gradually ignored the words of his peers and didn’t listen to them. When he turned to visit the small building, Zhao Paner’s eyes were still gentle and watery, as if penetrating his heart. At a loss, he had to avoid looking, but he couldn’t help looking in the direction of the pavilion from time to time, showing nostalgia and concern.

Moonlight gently sprinkled on the lake, lingering and lingering, and Zhao Paner watched the boat go away. "whose boat is flat tonight, where to miss the bright moon building." Silent language, with only two people’s eyes and natural scenery, expresses implicit love, which makes people feel unfinished.

The conversation under the umbrella in episode 6, scene selection and composition are very interesting. The background environment is rainy, and the umbrella held by the man and the woman is used to isolate other people in the same space. The camera focuses on the two people, highlighting the main body, making the background completely in Jiao Wai, which enriches the three-dimensional sense of the picture, meaning that this moment is the time exclusively for the two of them, providing a unique space for the next two people to talk.

The raindrops pattering on the umbrella not only created a cold atmosphere, but also narrowed the distance between them, bringing out the psychological changes of the man and the woman, and making them feel depressed. "Holding hands and looking at tears, I was speechless."

The emotion expressed in this lens language is very rich. The concern, awkwardness, pulling and attachment of two people, each picture conveys different emotions to the audience.

On the moon, the willow shoots, and people meet after dusk. In the evening, the sun is setting in the west, and they flirt. When crossing the bridge, Zhao Paner was holding a paper umbrella, and the man was holding the box, chatting while walking, his eyes staring at each other. Although it is a distant vision, there is no voice of conversation between them, but the distance between them and the direction in which their eyes look fully show their mood and relationship at this time.

This shot is poetic and picturesque, and I can’t get tired of watching it. Only a few seconds of a silhouette shot, full of story, made many viewers pause to enjoy this beautiful and romantic scene, and was also made into wallpaper by screenshots.

Meng Hua Lu, whether it is the lens language or the script lines, is carefully polished. The picture is no longer a ten-stage skinning beauty filter for domestic dramas. The lines are properly worded and flowing, the plot is fascinating and natural, and the actors’ acting skills are up to standard without any serious injuries.

Although the recent online comments on Meng Hua Lu are mixed, it is full of some discordant remarks. But on the whole, the film is exquisite in production, high in quality, picturesque and beautiful in picture, and the lens design is rich in layers and originality, which is very worth seeing!

In 2003, highly pathogenic avian influenza (HPAI) broke out in Southeast Asia. Until recently, HPAI only broke out in Indonesia, Viet Nam, Thailand, Laos, Cambodia and China and other eastern Asian countries. But from April to June, 2005, more than 6,000 migratory birds died of H5N1 in Qinghai Lake, China. In July 2005, H5N1 outbreaks also occurred in Russia and Kazakhstan. In August, 2005, a wild bird died of H5N1 in a lake area in northern Mongolia. In October 2005, poultry or wild birds infected with H5N1 were also detected in European countries such as Turkey, Romania, Greece, Sweden and Britain. The H5N1 avian influenza epidemic broke out in Anhui, Hunan and Liaoning. This worldwide outbreak of avian influenza has caused a large number of poultry to be killed and infected people. As of November 2, 2005, 122 people have been found to be infected with H5N1, of which 62 died [1]. The worldwide outbreak of H5N1 highly pathogenic avian influenza has caused great losses to agriculture and aquaculture, posed a serious threat to human life safety, and attracted worldwide attention. The worldwide outbreak of HPAI can easily remind people of the role of migratory birds in the spread of avian influenza, because migratory birds have the ability of long-distance migration across national boundaries, and they are regarded as a major carrier of avian influenza virus. However, based on the existing facts, it is still difficult to determine the role of migratory birds in the spread of avian influenza.The outbreak of avian influenza in 2005 showed some characteristics different from previous outbreaks. The research work is still going on. Although the role of wild birds in the spread of avian influenza is still controversial, it is urgent to establish a monitoring network for wild birds and conduct a dynamic study on the epidemiology of avian influenza virus.

1 influenza virus characteristics

Avian influenza virus belongs to Orthomyxoviridae. According to nuclear protein (NP) and membrane protein (M1), it can be divided into three types: A, B and C. According to hemagglutinin (HA) and neuraminidase (NA), influenza A virus is further divided into subtype 2. Up to now, 16 HA (H1-H16) and 9 NA (N1-N9) influenza virus subtypes have been found, and H5N1 is one of the virus subtypes 3.

According to the pathogenicity, avian influenza viruses can be divided into HPAI and LPAI (low pathogenicity avian influenza virus). LPAI is often parasitic in the respiratory and digestive systems of birds, and generally does not cause pathological reactions, or only causes mild pathological symptoms. However, HPAI can infect various tissues and cells of the host, causing various organs of the host to fail, leading to death, and its mortality rate is as high as 100%. Up to now, all the HPAI found are H5 and H7 subtype influenza viruses. LPAI can be transformed into HPAI4 through the change of amino acid site in HA0 cleavage region.

Influenza A virus has been isolated from many animals, including humans, pigs, horses, seals and wild birds. The phylogenetic study of influenza A virus found that influenza A virus has host interspecific relationship, and other animal influenza A viruses originated from waterfowl influenza A virus 5.

The wild migratory birds themselves are the natural reservoir of bird flu.

All virus subtypes of 16 kinds of HA and 9 kinds of NA have been found in aquatic bird populations. Stakkknecht and Shane isolated 2,317 strains of virus from 21,318 birds, with a carrying rate of 10.9%, including 14,303 birds of the order Animalia, and 2,173 strains of virus were detected (15.2%). Except for geese and ducks, the carrying rate of influenza virus in other birds was only (2.1%) 6. It is worth noting that influenza A virus seems to have achieved an ideal parasitic adaptation in the host of wild birds. LPAI is parasitic in the digestive or respiratory system of the host. LPAI isolated from most wild birds is nontoxic, and the host has no symptoms or only mild symptoms. The transmission between birds can be directly or indirectly through dust, water, food and other pollutants contaminated by feces. LPAI may be transmitted to poultry through contact between wild birds and poultry, and mutate in poultry population, leading to HPAI. Poultry infected with HPAI can lead to systemic infection. Clinical symptoms include decreased egg production, dyspnea, excessive tears, brain edema, diarrhea and neurological symptoms that eventually lead to death. But so far, there is no more evidence to prove that wild birds are natural reservoir of HPAI. Therefore, there is a theory of HPAI outbreak mechanism that only when LPAI in wild waterfowl spreads to poultry such as chickens or turkeys, and LPAI mutates into HPAI in poultry, will it lead to the outbreak of highly pathogenic avian influenza. Since 1959,There were 19 incidents in which LPAI from wild birds was transmitted to poultry and mutated into HPAI in poultry, which eventually led to the outbreak of the epidemic.

3 Debate about Wild Birds as Spreaders of HPAI

It is precisely because wild birds are the natural reservoir of avian influenza virus, and the migratory route of migratory birds can obviously connect Asian countries with the outbreak points of H5N1 avian influenza in Siberia, Kazakhstan and Europe. Therefore, when HPAI was raging, some people suspected that migratory birds were spreading the bird flu virus. But so far, no clear source of H5N1 HPAI that ravaged Asia in 2005 has been found. It is speculated that before the outbreak of HPAI in domestic chickens in Hong Kong in 1997, LPAI, the predecessor of this kind of HPAI, might parasitize the wild waterfowl population in southern China and spread and evolve, and then contact with poultry in Hong Kong through some channels. LPAI mutated into HPAI and broke out in 2003. The Hong Kong government controlled the outbreak of bird flu by killing 1.5 million poultry. Then, in December 2003, the virus once again ravaged Korean chicken farms. Outbreaks in Japan and Vietnam in January 2004; An epidemic was discovered in Indonesia in February; It soon led to outbreaks in Thailand and China.

But many ornithologists doubt the hypothesis that wild birds infect avian influenza. First, since the late 1990s, the United States Department of Agriculture has detected tens of thousands of migratory birds migrating from Asia to Alaska, and Hong Kong researchers have also sampled thousands of inbound migratory birds, but none of these tens of thousands of wild bird samples have detected H5N1 subtype. Up to now, the research results show that the H5N1 strain that causes high mortality of poultry is also pathogenic to wild birds. Wild birds infected with HPAI will also get sick and die. When the host dies, the spread of the virus stops, and the spread chain of the virus is interrupted. Secondly, the transmission path and outbreak time of avian influenza are not very consistent with the migration path and migration time of migratory birds. Although wild birds are the natural reservoir of avian influenza, it is not entirely accurate to blame wild birds for the outbreak of HPAI. Because in addition to the migration of migratory birds, bird flu may be spread, the backward feeding methods of mixing livestock and poultry with wild birds provide an ideal environment for the mutation and breeding of bird flu virus, and human activities such as frequent poultry trade and wildlife smuggling may play an unimaginable role in the spread of the virus. For example, in January 2004, an outbreak of H5N1 occurred in Lhasa, Xizang, which was finally found to be caused by selling a batch of sick poultry from Lanzhou, Gansu, 1500 kilometers away to Lhasa. An even more surprising incident occurred in Brussels. In October 2004, two crested eagles smuggled into Belgium from Bangkok Bird Market were seized at Brussels Airport.And detected that it has been infected with H5N1 virus. Therefore, many biologists are skeptical about the hypothesis that migratory birds spread avian influenza virus.

While people are arguing about the role of wild birds in the spread of avian influenza, the H5N1 outbreak in 2005 showed several aspects different from previous epidemics. Until the spring of 2005, there had not been any death of wild birds infected with H5N1 virus. However, in April 2005, the H5N1 outbreak in Qinghai Lake killed more than 6,000 migratory birds. At present, researchers are still investigating the causes and possible consequences of the outbreak of H5N1 in Qinghai Lake.

Then in August, 2005, wild birds in Lake Irkher in Mongolia also died of H5N1 infection. There are few poultry farms in Lake Irhull. It is likely that wild birds infected with H5N1 brought the virus to Lake Irhull, and the US Department of Agriculture only detected H5N1 strains in dead birds, but not in other living ducks, gulls, geese and swans. It is not known which kind of birds spread the virus, which may be very difficult, because there is very little research work on avian influenza virus in other birds except waterfowl. While the research work is still in progress, in October 2005, several European countries in Caspian Sea, Black Sea and Mediterranean Sea broke out one after another, which made more and more people believe that wild birds played a role in the spread of avian influenza.

In October 2005, an outbreak of avian influenza occurred in Hunan, Anhui and Liaoning, and the state took decisive measures to control the epidemic. Some experts said that the epidemic focus may come from migratory birds 9.

4. Establish a wild bird influenza virus monitoring network and strengthen

Protection of wild bird resources

While the role of wild birds in the transmission of avian influenza is still controversial, Europe has begun to establish a European-wide investigation and monitoring network for wild birds. Researchers in the Netherlands have collected more than 6,000 bird samples on the migration routes of European migratory birds. The monitoring network is not only to study the role of wild birds in the spread of avian influenza, but also to monitor the changing direction of avian influenza epidemic, study the variation law of avian influenza virus, and provide valuable data for preventing the outbreak of avian influenza.

Because all the influenza strains in the history of human influenza outbreaks are new strains formed by the recombination of avian influenza strains and human influenza strains, it is difficult for human immune system to play a role in the face of this new strain, and it is difficult for vaccines based on unchanged strains to play a role in the new strain, so it is easy to trigger human influenza outbreaks, resulting in significant economic losses and human death. The wild bird influenza epidemic monitoring network can not only be used as an early warning network for human influenza outbreaks, but also monitor the variation direction of viruses, providing reliable data for vaccine development, and developing vaccine strains that may cause influenza outbreaks before influenza outbreaks, thus changing the previous practice that vaccines can only be developed after influenza outbreaks. In addition, this monitoring network can also monitor the changes of antiviral drug resistance of viruses for a long time to ensure the effectiveness of antiviral drugs in the emergency of influenza outbreak. At present, it has been found that avian influenza virus has developed resistance to interferents based on hemagglutinin (such as amantadine); The interferents developed based on neuraminidase mainly include Tamiflu produced by Roche and Rekenza produced by Gkaxo Smith Kkine. Recent studies have found that influenza virus has produced a few resistance to Tamiflu, while Rekenza has not found any record of resistance because of its low dosage. Therefore, governments around the world should pay attention to the problem of drug resistance while stockpiling antiviral drugs. Use the monitoring network to monitor the virus for a long time,The problem of drug failure caused by drug resistance can be found in time.

Therefore, it is of great significance to establish an influenza surveillance network for wild birds. In the face of severe avian influenza epidemic, China should immediately set up its own wild bird monitoring network, study the role of wild birds in the outbreak of avian influenza, find key hosts, study the transformation and variation law between LPAI and HPAI, monitor the direction of virus variation, and provide reference for vaccine development, and monitor the change of virus resistance, so as to provide reference for the development and storage of antiviral drugs.

5 conclusion

The role of wild birds in the spread and outbreak of avian influenza is still controversial. By analyzing the existing evidence, it is still impossible to confirm the role played by wild migratory birds in the spread of avian influenza. After more than one year’s molecular epidemiological investigation of avian influenza, although it has not been confirmed that wild birds are natural reservoir of HPAI, it can be confirmed that wild birds can be infected with HPAI H5N1 virus, not only migratory birds but also resident birds. All kinds of facts remind us that the outbreak and epidemic of HPAI H5N1 in the world may include the repeated transmission link of "wild birds → poultry → wild birds → poultry", and each host transfer and repetition may enhance the toxicity of the virus.

LPAI can mutate cyclically in poultry and wild birds until the HPAI epidemic occurs. HPAI virus is fatal to poultry and wild birds that originated in the first place. Infected wild birds are often dying or dying, which may affect their ability to spread the virus over a long distance. The fact that migratory birds in Qinghai Lake are infected with avian influenza reveals that H5N1 virus can spread among wild birds. However, these viruses are collected from dead or dying individuals, and they are the ultimate hosts. The further monitoring results of migratory birds that survived the bird flu control in Qinghai Lake will prove whether it is possible for migratory birds in Qinghai Lake to spread the virus with migration. At present, before we fully understand the role of migratory bird migration in the process of bird flu transmission, we should not blindly assume that HPAI has nothing to do with migratory bird migration, nor should we ignore the role of migratory bird migration in bird flu transmission. In addition, a very important point is often overlooked by everyone, that is, keeping birds. Previous studies mainly focused on migratory birds, and recently HPAI virus was detected in resident birds. If HPAI H5N1 can be isolated from a large number of healthy birds, it will be the biggest threat for human beings to prevent and control avian influenza.

From the perspective of logistics, environment and biodiversity, it is difficult to control avian influenza infection in wild birds at this stage. Indiscriminately killing wild birds is ineffective in preventing the spread of avian influenza, and it is likely to cause the extinction of wild birds.

In addition to paying attention to the role of wild birds in avian influenza, limiting the contact between poultry and wild birds should be a key part of avian influenza prevention strategy. We should reduce the contact between people, poultry and wild birds as much as possible, improve the level of poultry raising and avoid free-range; Strictly manage the poultry and wildlife trading market; Strengthen quarantine and immunization work; Put an end to illegal unlicensed poultry and wildlife trade.

In order to prevent the spread of HPAI, it is urgent to carry out scientific research on wildlife diseases. Establish a monitoring network for avian influenza in poultry and wild birds. Monitoring, sampling and analyzing the evolution and variation of avian influenza subtype virus in wild birds. Establish and improve the laboratory research ability to quickly detect and analyze the characteristics and types of viruses. Establish a perfect monitoring network of wild bird epidemic focus in order to quickly respond to virus emergencies and provide timely reference for national decision-making. Long-term monitoring and detection of avian influenza epidemic situation. Investigate the wild host distribution of avian influenza virus, study the variation law of the virus, determine the distribution, types and natural history of avian influenza virus in wild birds, and explore the relationship between wild migratory birds and agriculture and aquaculture structure and its role in the transmission of avian influenza virus to poultry and people. Develop and reserve safe vaccines and antiviral drugs against avian influenza virus. Organize veterinarians, wildlife experts, ornithologists, virologists, molecular biologists and other multidisciplinary experts to jointly study the changing law of avian influenza, fully understand the role of wild birds in the spread and spread of avian influenza virus, and prevent the outbreak of avian influenza and human influenza.

　　On April 14th, 2012, in Chengdu, the students who took the Olympic Mathematics Examination walked out of the examination room. (Information photo photography Wu Xiaochuan)

　　Who is the Olympics suitable for?

　　Chen Ping, an expert on the proposition of the National Primary School Olympiad 4 Cup, believes that only 5% of the people are suitable for Olympic math training & mdash; 8%。 Even if the National People’s Congress is attached to the middle school, less than 15% of the students are suitable.

　　Teacher Fan of Southwest Jiaotong University believes that whether primary school students are suitable for learning Olympic Mathematics should not be simply based on math scores.

　　There is something wrong with olympiad

　　Chen Ping believes that the current penetration rate of the Olympic Mathematical Market has far exceeded the reasonable range, which is not beneficial to unsuitable students.

　　In addition, the Olympic Mathematics is only a supplement to the expansion of school learning, and should not be used as an indicator for further studies.

　　Recently, a post about elementary school olympiad was frequently forwarded in the circle of friends. After reading the post, many people shouted "the topic is poisonous", and some netizens vomited, "Is this to train students into a neurotic patient?"

　　For being "hacked" again, many Olympic math teachers even called "lying guns". Chen Ping, director of the National Organizing Committee for Exploring the Mathematics Garden (Spring Cup), clarified to the reporter of Huaxi Dushi Bao that the topics in the post are not Olympic math questions — — This "Olympiad Mathematics in Primary School" question is adapted from some IQ tests in the early years of the United States.

　　In response to Olympiad Education’s query, Chen Ping said frankly that only 5% of the students are suitable for Olympic Mathematics training & mdash; 8%, but at present, the penetration rate of the Olympic Games market has far exceeded the reasonable range, which is not good for unsuitable students.

　　In addition, Teacher Fan, who teaches mathematics at Southwest Jiaotong University, believes that whether primary school students are suitable for learning Olympic Mathematics should not simply examine their math scores, but also their reaction and interest in math problems.

　　Shentie

　　Recently, a post about primary school Olympic math was frequently forwarded in the circle of friends, and parents vomited: this Olympic math problem is too unusual. Look — —

　　How many questions can you do correctly in this "Primary School Olympiad"?

　　1. (Jiangsu Nanjing Grade Four) Observe the following Chinese characters and find the rules to fill in the blanks.

　　Ligan and Tian A, Feng B, Lin C, Huo D, Shan

　　"Is this really a math problem?" The netizen picked up his skull, "‘ Force ’ 2 pens, ‘ Fuck ’ 3 pens, ‘ And ’ 3 pens, amount … … It seems that strokes don’t work. "

　　The announcement of the answer made everyone "cry": choose A, because every word has a cross structure.

　　The next topic continues to "torment" netizens.

　　2. (Jiangsu Yancheng Grade 4) Observe the following Chinese characters and find the rules to fill in the blanks.

　　Xigang Kouri A, A B, Hui C, Chang D, Tong

　　"strokes? There is no hope. Cross? I didn’t do it How many sections are closed? Who can show me the way! "

　　Seeing the answer, netizens can only "surrender": choose C. The first word has a right angle, the second word has two, the third word has four and the fourth word has eight, so the fifth word must have 16 right angles.

　　"Right angle? Isn’t it for graphics? " "Right angle in Chinese characters? What is this God perspective? " Helpless netizens silently saw the next question:

　　3. (Shandong Jinan Grade 3) Find a rule to fill in the blanks.

　　1，10，5，4，7，，9，6

　　"Well, finally have a math problem. Let me see how the option uses exclusion. "

　　Options: A, I B, Love C, Count D, Learn "is a Chinese character? Does the stroke of the word represent the answer? For example, ‘ I ’ It is 7 paintings and the answer is 7, so choose A. "

　　After thinking hard, seeing the answer, netizens can’t calm down: choose D. These numbers are arranged in the order of the first sound, the second sound, the third sound and the fourth sound, and "learning" is the second sound.

　　Seeing the last question, the netizen breathed a sigh of relief, "the authentic math problem is coming."

　　4. (Guangdong, Guangzhou, Grade 6) Observe the following figures and find the rules.

　　1，4，3，11，2，0，7，12，6，，8，30…

　　A.9 B.14 C。 -1 D.32 the answer is a. Why? The analysis is as follows: after the topic is changed into English, it is one, four, three, seven, two, zero, seven, twenty, six, eight, thirty… There should be a four-letter word in brackets, and only nine matches it.

　　"Can’t you have a good mathematical solution?" Some netizens left a message, "I still tore up the first prize certificate of the Olympic Mathematics."

　　After the topic was highlighted, the post showed his point of view, "The primary school olympiad is very unhappy — — Too anti-human! " The poster thinks that it is not advisable for children to be immature and impose too many messy things.

　　However, many Olympic math teachers have "cried grievances" about this, saying that the topic in the post is not an Olympic math topic. This time, the brush screen is purely lying down.

　　seek to prove

　　The Olympic math test questions have to be mathematical questions, and these questions have nothing to do with mathematics except simple numerical relations.

　　The IQ test questions are "olympiad" when they are compiled and turned around.

　　If this is not an Olympic math problem, what is it?

　　On September 12th, the reporter of Huaxi Dushi Bao contacted Chen Ping, director of the National Organizing Committee of Mathematics Garden Exploration (Spring Cup), who is now presiding over or participating in three competition propositions in the 4 major primary school Olympic Games, and at the same time providing attractive IQ test questions for many lT and financial enterprises listed on the main board or in the United States.

　　Chen Ping made it clear that the topics in the post are not Olympic math questions. First of all, the Olympic math test questions have to be mathematical questions, and these questions have nothing to do with mathematics except simple numerical relations. Secondly, the Olympic math test questions require rigor and objectivity, and there is only one correct answer, but these questions have more than one correct answer.

　　Tracing back to the source, Chen Ping believes that these questions with the label of elementary school olympiad first came from some IQ test questions in the early years of the United States, and then they were adapted by a few people and copied from each other inside and outside the circle.

　　"IQ test questions are very different from Olympic math questions." Chen Ping said that the Olympic Mathematics is based on mathematics and emphasizes corresponding thinking. Good Olympic Mathematics questions require higher thinking depth. The IQ test questions test the thinking level of participating users in different aspects through different types of questions and different directions. A similar assessment has been made in the early training sea election divination of the middle school affiliated to Beijing People’s Congress. "But it is always used, and the IQ test is not allowed. Now, the IQ tests of the National People’s University High School and the United States are constantly changing. "

　　answer questions

　　What kind of children are suitable for learning Olympic Mathematics? It must be combined with students’ thinking ability, interest level and will quality.

　　Olympic math expert: being tied up for further study is the key to the problem

　　All along, the Olympic Mathematics has been at the forefront. Some people say that it is a good way to exercise thinking, and some people say that it is a villain who tortures students.

　　Ms. Wen’s sons in the sixth grade all scored more than 115 points in mathematics (with a total score of 120 points). She said that the Olympic Mathematics has promoted her son’s interest in mathematics, and he has more ideas to solve problems after learning. Mr. Yu said that in fact, his children are not interested in the Olympic Mathematics. "But considering that they may become extra points when they go to school, let him try to learn."

　　Regarding the current situation of Olympic Mathematics, Chen Ping responded that Olympic Mathematics training was originally aimed at a specific group of people, and only 5%-mdash; 8% of the population. At present, the penetration rate of the Olympic Mathematics market has far exceeded the reasonable range, which is not beneficial to unsuitable students.

　　What kind of children are suitable for learning Olympic Mathematics? Chen Ping said that it depends on students’ thinking ability, interest level and will quality. If students do not meet the requirements, then teachers can only make them memorize, but this is not conducive to the growth of students. In addition, the serious expansion of Olympic Mathematics will also lead to uneven teachers of Olympic Mathematics. In the 1990s, there were only twenty or thirty qualified Olympic math teachers in Beijing, and now there are thousands of them.

　　Finally, Chen Ping bluntly said that the Olympic Mathematics is only an expansion and supplement to on-campus learning, and should not be used as an indicator for further studies.

　　Math teacher: Good math scores may not work.

　　In the Olympic Mathematics class, you can often see the first-year students. In this regard, Teacher Fan, a traffic math teacher in Southwest China, believes that although his children are good at math, they only enrolled in the off-campus math competition training in the next semester of the fifth grade. If parents can’t coach their children, it is recommended to take part in the third and fourth grades. In the primary stage of primary school, we should cultivate other hobbies.

　　"Parents should also evaluate their children’s learning." Teacher Fan believes that the basic knowledge should be paid attention to in the study of Olympic Mathematics, and many students ignore the study of definition concepts and only use formulas to solve problems, which can not lay a good mathematical foundation and thus lose the significance of learning.

　　Teacher Fan believes that for primary school students, whether it is suitable to learn Olympic Mathematics should not simply look at their math scores, but also look at their reaction and interest in math problems. Although many practical and careful students can get good grades, they are not sensitive enough to mathematics and are not suitable for participating in competitions.

　　Teacher Fan said that there is no original sin in the Olympiad itself. If it is out of children’s own interest, it is definitely beneficial to learn more. However, once the olympiad is linked to utilitarian purposes such as adding points and winning prizes, it becomes a burden and even a nightmare.

　　Huaxi Dushi Bao reporter Mao Yuting

　　Reporter’s notes

　　Who alienated the Olympiad?

　　Competition mathematics has existed for a long time, and the word "Olympiad Mathematics" was born in the 1960s and 1970s. In line with the Olympic spirit, China children have won many honors internationally. Therefore, parents yearn for a "child prodigy" at home, or force or persuade them to send their children to the Olympics class.

　　Or for the sake of honor, some schools also use Olympiad as an admission index by stealth. As a result, the coverage of the Olympic Games market in first-tier cities has reached 70%. In the interview, Chen Ping bluntly said that even in the middle school attached to the National People’s Congress, it was only 10%— 15% students are suitable for Olympic Mathematics training.

　　But what about the students of "National Olympics"? Some people can’t solve the problem, have a fear of difficulties, and even recite the problem in order to achieve the expected effect.

　　Under the "magic" of the baton, both the child and the Olympiad lost their natural features. Olympiad Mathematics, like music and airplane models, can make children’s thinking grow freely. Once it is linked with utilitarian purposes, it is no longer a specialty and interest that inspires children, but a nightmare that tortures people.

　　Is this the fault of Olympiad? Olympic Mathematics should be regarded as a learning hobby rather than a nightmare in the eyes of some parents and students. There is no original sin in the Olympiad itself, but it is wrong to use it as a "tool" for further study. Let the Olympiad grow freely and let the children grow naturally, which is the purpose of the Olympic Games.
