Chen Chusheng, a voice that runs through 2007, can always sing a life story with deep affection. However, such a voice was silent for a long time, and it was not until he boarded the stage of Hunan Satellite TV’s "Who is the Treasure Singer" that everyone found him again.

Chen Chusheng appeared as an "equal sign" singer, and the recommender Luo Yonghao asked the most concerned question on behalf of everyone: "I haven’t heard from you for many years. What have you been busy with these years?" Chen Chusheng said frankly in the program that in fact, he has been playing bands and making music, but it is different from the past era of "wine is not afraid of the depth of the alley". Now he needs to work hard to let more people know that he is still singing and making music. "If there is such an opportunity for more people to hear, I am willing to start again, starting with the’ equal sign’."

Tomorrow night, "Who is the Treasure Singer" will usher in a "highlight night". At the end of the program, Chen Chusheng was interviewed by the national media, including the story of catching entertainment (ID: IBUYUJI), and shared his feelings about the program and his musical journey.

"Very compact and exciting."

After receiving the invitation from director Hong Tao, Chen Chusheng promised to be on "Who is the Treasure Singer" with little consideration. He said that if he wants to meet young and powerful musicians, he also wants to test his efforts in music over the past few years. "This time I came to the show to hope to put aside all my past achievements, go into battle easily, face every singing seriously and enjoy the stage to the fullest."

Every treasure singer will replace his name with a "symbol" before revealing his name. Chen Chusheng chose "=" (equal sign). When the familiar "Did anyone ever tell you" sang again, everyone was moved. This is indeed a voice that everyone has been waiting for for a long time.

Arai XI, the presenter of the program, was deeply moved: "I used to have a lot of singers, but I am still willing to stand here anonymously." The music critic Er Di commented that the new version of Did Anyone Tell You has a sense of sadness and infiltration. "With the sad strings that are not what they used to be, it is a feeling that’ things are people who don’t rest everything, and tears flow first’, which shows that there is a deeper understanding of singing."

After years of tempering, the voice is more pure. Chen Chusheng maintains his awe of the stage. He admits that he is very nervous. "After all, he has not sung on such a stage for a long time." The tension continued until he sang "Mercury" with Land Rover, and his familiar old friends made him relax a lot.

Talking about the "trip to the treasure", Chen Chusheng admitted that the biggest gain was "enjoyment". There is no teleprompter on this stage, and every song is required to be thoroughly understood and integrated into your own understanding. In the duet session, you have to cooperate with your partner in many harmonies. "It is very compact, but it is also very exciting, so you will still feel very happy after singing, especially if you don’t forget so many words."

"Who is the Treasure Singer" includes Mesozoic singers such as Manjiang, Hannah Kim and Jiang Meiqi, as well as new generation singers such as the landlord’s cat and ICE PAPER. Chen Chusheng obviously feels a change. He said, on a stage similar to the T-stage, "You will see a lot of new generation singers who will express themselves on different stage forms and make full use of this stage. When we talk about singing, we actually (except) sing well, so we have to think about how to perform it. I think this part needs me to learn, that is, how to make full use of different stages to express my different forms, so that people on the scene or the whole visual effect can be integrated with music to maximize the enjoyment of visual hearing. "

"slowly pick up the memories"

"I am a singer, and my clue is’ I am No.09 player’." When Chen Chusheng first appeared, he introduced himself like this. 09 is the number when he participated in Happy Boys in 2007, when countless viewers voted for this number. Returning to the stage, Chen Chusheng saw many familiar IDs and names, and "felt very cordial". Happily, there are also many new IDs. "These people know me in this program, which is also a very happy thing for me."

In the "Who is the Treasure Singer" program, there is also a good brother of Chen Chusheng, the "No.07 player" Land Rover. They sang two songs together, and the singing video was circled on social networks, which caused praise and heated discussion.

One is "To My Former Self", which starts with the numbers of "No.09 Chen Chusheng" and "No.05 Land Rover" in the fast boy period, and instantly brings back the youthful memories of the audience. The audience commented on the tacit understanding and passion of the two people’s singing. "The narrative tone tells the story of their experiences and moods along the way. Even if time passes, the past is not like smoke. It is still a burning flame that ignites their love for music and cherishes their friendship."

One is Mercury, an excellent musical work that has been covered many times. Chen Chusheng and Lu Hu’s singing kept the artistic conception and emotional expression of the original version to the greatest extent, faithfully presented the lonely surroundings created by Guo Ding, and explained it again with the most sincere and sincere emotions. They seem to be carefully caring for a song, and their eyes are sincere and pure, moving.

How do you feel about being on the same stage with Land Rover after 14 years? Chen Chusheng said, in fact, this is the first time they sang in the same stage. "We will talk about many things we experienced together in the past and slowly pick up many memories. I am very happy to have such an opportunity to sing with him, and I can also see each other’s growth through this singing on the same stage. How to say it is very warm, because two people are familiar with each other and the communication on music is very fast. In this process, it is very smooth and very happy. "

“haveGood work,alsoLet people hear you"

The recommender Luo Yonghao was very excited to see Chen Chusheng in Who is the Treasure Singer. "I haven’t heard from you for many years. What have you been busy with these years?"

Different from the fate of most draft champions, Chen Chusheng’s "debut is the peak". In his 26-to 36-year-old golden decade, he experienced highs and lows, and he was confused and gained happiness. Although there was a lot of repercussions when he kicked the Hunan Satellite TV "Singer" program in 2019, he turned around and disappeared. Later, the audience actually saw him in a program that tested his acting skills.

In fact, Chen Chusheng did not leave music. In 2014, after his contract with Huayi Music expired, he set up an independent studio and formed a five-person band SPY.C After that, he was active in music festivals and band tours as the lead singer of the band. Chen Chusheng said, "The most influential person in my music career is Ka Kui Wong. I learned guitar because I watched the videos of their concerts, and I was also influenced by them in writing words, including forming a band. "

In order to show the diversity of music styles, Chen Chusheng specially sang a disco-style Evening Dress in Who is the Treasure Singer. "I chose this song because I hope more people can understand Chen Chusheng’s music content, which may not be as simple as most people think. In fact, I have been doing a lot with the band from my second and third albums to the album Detective C with my own band SPY.C Chen Chusheng said that through the expression of Evening Dress, I want to communicate with you and let more people know. "In fact, there is more room for imagination in Chen Chusheng’s music, and I have been doing this all these years."

There is good music, but it is difficult to be heard by the public. This is a big dilemma that Chen Chusheng is facing at present. He admits that now is the era of information explosion and streaming media, and everyone can be from the media. "If you want others to pay attention to you, in addition to the good works you can get, you must let people hear and see. Maybe I am more traditional from the media. Unlike many young musicians now, they are doing very well in this piece. I also hope that I can learn more. "

Participating in "Who is the Treasure Singer" has gained a lot, and more people have heard their own voices. Chen Chusheng is ready to start again. "In fact, Chu Sheng has been making music seriously in recent years, seriously facing every album."

China new blind date　|The Glory of Youth

We are new to the workplace.　|　pet hospital

Wan Li rode alone.|　Word of Honor

After crouching

The high temperature in various places continues to spread.

Some people don’t pay attention to it after heatstroke.

Wait until after severe heatstroke

The tragedy is irreversible …

In the past week, the emergency department of Sandun Hospital of Zhejiang Hospital has received many cases of heatstroke every day. A 30-year-old female patient with heatstroke (severe heatstroke) did not turn on the air conditioner at home, and the electric fan was given to the child. By the time the family found out that she was not in the right condition, the patient had fallen into a deep coma.

What took you so long? Her husband explained that "she is not afraid of heat at ordinary times". In the end, the doctors tried their best, but there was nothing they could do.

The doctor stressed that heatstroke is severe heatstroke, and the mortality rate is very high if the rescue is not timely. However, heatstroke usually does not happen suddenly. If there is threatened heatstroke or mild heatstroke, we must intervene in time, otherwise the symptoms will continue to worsen, such as heatstroke and even death.

On the social platform, related topics also rushed to the hot search.

Netizens said

"Poor inherit the wind"

Some netizens don’t understand her husband’s words.

Xiao Bian reminds that in high temperature weather, whether in production or life, we should guard against the personal safety risks caused by summer heat.

Eight Mistakes of Heat Shock Disease

Misunderstanding 1

Heat stroke is heatstroke, so it is not life-threatening.

Heat stroke is the most serious type of severe heatstroke. Heat stroke is not as simple as raising body temperature, but produces a series of terrible physiological reactions. Patients will have multiple organ failure, central nervous system dysfunction, disseminated intravascular coagulation and so on. If it is not properly treated in time, the death rate of heat stroke is very high, and the general death rate can reach 50%-70%, and the death rate of elderly patients over 70 years old will reach 80%.

Myth 2

If you have symptoms of heatstroke, you can cool down at home.

Heatstroke is extremely dangerous once it develops to the stage of heatstroke. When the patient has symptoms of heatstroke such as high fever, no sweat, blurred consciousness, convulsion, or even no response, don’t hesitate to call 120 in time and send him to the hospital as soon as possible.

Misunderstanding 3

Indoor, there will be no heat stroke.

Heat stroke is not exclusive to outdoor, and indoor small environment with high temperature and poor ventilation may also cause heat stroke. Decoration workers and workshop workers who stay in a closed space for a long time belong to the high-risk group of heat stroke; Some elderly people live in old houses with poor ventilation and no air conditioning, and are also prone to heat stroke.

Misunderstanding 4

If you don’t do strenuous exercise, you won’t get heatstroke.

Heat stroke can be divided into labor type and non-labor type, the former refers to strenuous exercise in summer and high-intensity physical activity; The latter is common in the elderly, infants, pregnant women and other people with slightly weaker physique. In the summer of 2022, there was an incident in Shandong where a woman suffered from fever during the confinement period and eventually died of heatstroke.

Myth 5

If the temperature is not high, it is not heatstroke.

Elevated body temperature is the main feature of heatstroke, and the core body temperature of patients is mostly above 40℃. The core temperature mentioned here is often reflected by rectal temperature. Our daily measurement of axillary temperature or ear temperature can only be used as a reference, and can not be used as a basis for the diagnosis of heatstroke.

Myth 6

Only in summer will there be heatstroke.

Heat stroke is not exclusive to summer. For example, workers who work in unventilated high-temperature factories for a long time, firefighters who face raging fires, and even people who steam saunas in winter may suffer from heat stroke.

Misunderstanding 7

In hot weather, eating more cold drinks can prevent heatstroke.

The most important thing to prevent heatstroke is to drink plenty of water, including white water, salt water and drinks containing electrolytes such as potassium, sodium and chlorine. Eating a lot of cold drinks will increase the burden on the stomach. Alcoholic drinks and high-sugar drinks will make the body lose water and are not recommended.

Misunderstanding 8

Women with weak constitution are more likely to get heatstroke.

Generally speaking, women’s heat adaptability is weaker than men’s, but a large number of clinical data show that there are more men suffering from heat stroke than women, which should be related to men’s more outdoor work and heavy physical activities. Such as outdoor high-temperature workers, steel workers, firefighters, athletes, soldiers participating in training, etc. are all high-risk groups of heat stroke.

Diffusion reminds people around you

The heat is scorching

Be sure to watch out for heatstroke!

　　In the past few years, various problems based on AI (artificial intelligence) have been one of the hottest topics in the field of science and technology. How to make this cutting-edge scientific and technological force simpler and acceptable to the people has become a real problem at present. In response to this problem, Baidu gave its own plan.

　　A few days ago, after reaching a strategic cooperation with China Science and Technology Museum, Baidu’s "Voyager" AI Popular Science Bus has started from Beijing, and has been launched in local science and technology museums in five cities across the country. On August 4, 2017, Baidu and science and technology hall held the launching ceremony of "Artificial Intelligence Popular Science China Tour" in Beijing, which marked the first stage of the strategic framework cooperation agreement reached between them based on artificial intelligence popular science. This trip of artificial intelligence science popularization in China has been carried out in local science and technology museums in five cities in China. The "Voyager" AI science popularization bus will spread the knowledge of artificial intelligence to all parts of the country, which also shows that Baidu’s artificial intelligence technology not only changes industries, but also cares about people’s lives. Bring updated artificial intelligence knowledge to further places. Prior to this, Baidu also successfully realized the "restoration" of the damaged Terracotta Warriors and Horses and the intelligent display of related cultural relics through artificial intelligence technology. In addition, Baidu is also committed to using the new AR (Augmented Reality) technology to restore and reproduce the folk life of old Beijing, and use technology to awaken history, so that experiencers can fully experience history and culture and become a part of history.

　　Make the complex world simpler.

　　In fact, it is Baidu’s mission to make the complex world simpler with technology. In the past few years, Baidu has been committed to technological innovation and the development of artificial intelligence. The reason why Baidu can achieve today’s achievements is closely related to the country’s concern and support for the field of scientific and technological innovation.

　　In order to realize the mission of "making the complex world simpler with technology", Baidu will adhere to two core strategies: consolidating the mobile foundation and winning the AI ? ? era. In short, AI is the core driving force of Baidu.

　　It is reported that Baidu AI platform is the foundation of developing application layer, which is composed of Baidu Brain and Baidu AI Cloud. Baidu brain is the first complete artificial intelligence platform in the industry, including algorithm layer, perception layer, cognition layer and platform layer. Baidu’s algorithm layer includes machine learning platform and deep learning platform; Perception layer includes speech recognition, image recognition, AR, VR (virtual reality) and other capabilities; The cognitive level includes NLP (natural language processing), knowledge map and user portrait; The platform layer is an AI open platform, which opens different capabilities to the outside world. Intelligent cloud is the foundation of Baidu AI platform, which is composed of AI+ big data+cloud.

　　At present, Baidu’s AI technology capability is accelerating at a solid pace. For developers and eco-partners, Baidu announced a number of important plans, including the Apollo plan for intelligent driving and the two open platforms for intelligent voice DuerOS, to fully launch Baidu’s important AI eco-strategies, technologies, business progress and solutions.

　　Up to now, in the field of artificial intelligence, Baidu has opened more than 60 AI core technologies, forming four major AI commercialization scenarios: airport, sales customer service, home and automobile. At the industrial chain level, only in the field of intelligent driving, more than 50 upstream and downstream manufacturers of the first-tier automobile industry at home and abroad have announced their participation in Baidu AI circle of friends in the three months since the announcement of the "Apollo Plan".

　　Baidu takes artificial intelligence as the driving force to continuously improve its existing core businesses, especially mobile phone Baidu, search, information flow and other core products. At the same time, in order to explore long-term market opportunities, Baidu will continue to expand emerging AI-driven businesses through open platforms and ecosystems.

　　Awakening history and culture with science and technology

　　Awakening history and culture with technology is one of the important practices undertaken by Baidu, the global artificial intelligence giant, in the field of AI, and it is also one of the most intuitive channels for the public to experience the power of AI at present.

　　On August 4th, 2017, Baidu and science and technology hall held the launching ceremony of "Artificial Intelligence Science Popularization in China" in Beijing, which marked the first stage of the strategic framework cooperation agreement reached between them based on artificial intelligence science popularization. This trip of artificial intelligence science popularization in China has been carried out in local science and technology museums in five cities in China. The "Voyager" AI science popularization bus will spread the knowledge of artificial intelligence to all parts of the country, which also shows that Baidu’s artificial intelligence technology not only changes industries, but also cares about people’s lives.

　　On May 18th this year, Baidu announced that it had realized the "restoration" of the damaged Terracotta Warriors and Horses and the intelligent display of related cultural relics through artificial intelligence technology. According to reports, the "restoration" plan uses AR technology to "restore" the Terracotta Warriors and Horses No.2 pit, kneeling figurines and bronze chariots and horses. Visitors can see the "alive" Terracotta Warriors and other cultural relics with their own eyes by scanning the three triggers of "plane layout", "light box of kneeling figurines" and "structure diagram of bronze chariots and horses" in the No.2 pit of Terracotta Warriors and Horses through Baidu AR function of mobile phone.

　　At the same time, the Digital Museum of Terracotta Warriors and Horses built by Baidu Encyclopedia was officially launched, presenting the Terracotta Warriors and Horses to the audience for the first time with the "ultra-high-definition level" of 20 billion pixels, becoming the first historical landscape in eight wonders of the world to be exhibited online with 10 billion pixels.

　　At the beginning of this year, following the restoration of Chaoyangmen by Baidu AR technology, Baidu began to comprehensively upgrade AR technology and completely restore the nine gates of old Beijing as cultural cities. It is reported that Baidu’s activity of restoring the nine gates of old Beijing through AR technology was held during the Spring Festival, so it has attracted the attention of many citizens and friends. During the event, passengers can see all kinds of life scenes of the old people in the old Beijing city after triggering AR through the mobile phone Baidu App, and at the same time, they can also interact with the restored "Old Nine Gates", which is very exciting.

　　Compared with some applications with a strong commercial atmosphere, Baidu’s attempt to awaken history and culture with technology and let the experiencers fully experience history and traditional culture with new AR technology can really make more and more people pay attention to and even participate in the inheritance and protection of history and culture. This also shows that Baidu’s artificial intelligence technology is not only about changing industries, but also about people’s lives themselves. Text/Liu Yang

　　With the rapid development of digital technology, artificial intelligence is becoming a core competitive advantage in the field of education. Its iterative upgrading has not only brought revolutionary changes to teaching practice, but also brought unprecedented creativity to the education industry. Ms. Fan Bo, general manager of Aiqiyi Quanzhixin Education, pointed out: With the development of artificial intelligence, it marks that the field of education is moving towards a brand-new era.

　　First of all, in terms of teaching mode, the application of artificial intelligence is changing the traditional dual structure of "teacher-student" and introducing the ternary teaching mode of "teacher-student-machine". The support of intelligent teaching tools and platforms has become the key. These tools can not only provide personalized learning paths, but also provide accurate teaching feedback for teachers through data analysis, so as to realize personalized teaching, make up for the weak links of strengthening students and maximize the teaching effect.

　　Secondly, under the teaching mode of man-machine cooperation, the role of teachers is changing. They are no longer simple knowledge transmitters, but become the motivators of students’ learning internal drive, guiding students to explore the ocean of knowledge. At the same time, teachers have changed from the leader of the teaching process to the leader of the education process, helping students to build a knowledge system and cultivate their autonomous learning ability.

　　At the same time, students’ autonomous learning ability is particularly important in this process. With the great enrichment of educational resources and the expansion of educational space, students can study in a more diverse and open environment, which is no longer limited by traditional classrooms. The application of cognitive model has changed the way of knowledge production and knowledge dissemination, and brought far-reaching influence to the field of education.

　　Ubiquitous education has once again taken the lead in educational innovation by using artificial intelligence (AIGC) technology, and launched a series of cutting-edge courses, aiming at training students to master and apply the latest AI-generated content (AIGC) technology. The courses of "AIGC Design" and "AIGC Writing" under the company are well received. At the same time, based on the existing audio and video transmission technology and intelligent network, Universal Education innovatively launched a variety of online education products and services, including live broadcast, interactive live broadcast, recording and broadcasting, interactive recording and broadcasting, AR, VR, MR and so on. Reach more users quickly and accurately through the big data intelligent recommendation system.

　　Our "AIGC Design" course will teach students how to use AI tools for creative design, including graphic design, UI/UX design, animation production and other fields. The course covers the operation skills of AI design tools, the innovative application of design concepts, the acquisition of design core typesetting and color matching skills, the disassembly of aesthetic principles and practical cases, etc., in order to cultivate students’ innovative thinking and practical ability.

　　The course "AIGC Writing" emphasizes practicality and innovation, especially its application in content creation, copywriting and news editing. The course will introduce the use of AI writing tools, teach students how to efficiently generate texts with AI assistance, and at the same time emphasize maintaining the unique perspective and creativity of human authors to ensure the originality and attractiveness of the content. In addition, the course also focuses on the creation and incubation of personal brands, guiding students how to give play to their personal interests and hobbies through creative content output, establish and enhance their personal IP influence, and achieve creative efficiency and dimension improvement, thus realizing more possibilities for self-media sideline and new careers. The project also won the award of "China Science and Technology Innovation Enterprise of the Year in 2023 -AIGC" in the new economic peak list of Ai Media, which is also a high recognition of the achievements of Universal Education in the field of AIGC.

　　Universal education has always been committed to promoting the development of education through technological innovation, which not only responds to the demand for updating educational content in the digital age, but also provides students with the necessary skills to adapt to the future workplace and increase their competitiveness in their careers.

　　In the future, Ubiquitous Education will continue to explore the deep integration and application of artificial intelligence technology and educational practice, provide students with more high-quality learning resources, and constantly promote the innovation and upgrading of education and teaching with the "golden key" of artificial intelligence.

　　Give you a heads-up

　　Every summer, all kinds of seemingly eloquent "popular science" are "listed" simultaneously with big and red cherries.

　　Recently, a video about the quality and safety of cherries spread on the Internet, saying that "99% of cherries on the market use swelling agents. Normal cherries can only grow to 12-mdash; The weight of 13 grams can be doubled with swelling agent. If there is no kernel in the cherry pit, the hollow one is medicated … …”

　　What is the swelling agent that is often named? Is there really a miraculous effect in the rumor? What factors are related to the size of the cherry? To this end, the reporter visited experts in the agricultural field and consulted people on issues of concern.

　　No food safety incidents caused by it have been found yet.

　　"The swelling agent is a plant growth regulator. In the process of cherry growth, in order to improve pollination rate and fruit setting rate, cherry planted in greenhouse usually needs to use swelling agent; Cherry cultivated in the open field does not need to be used. " Wang Qiang, a researcher at the Agricultural Products Quality and Safety Risk Assessment Laboratory (Hangzhou) of the Ministry of Agriculture and Rural Affairs, told the reporter that at present, open-field cherry is the mainstream cultivation mode in China. According to this calculation, it is indeed possible to use plant growth regulators such as bulking agents in cherry market, but the utilization rate should be less than 50%.

　　How do plant growth regulators play a role in the production of fruit and vegetable products?

　　"Plant growth regulators have similar effects to plant hormones, which can stimulate the division and growth of plant cells. The difference is that plant growth regulators are artificially synthesized by scientists and modified to make their activities stronger than plant hormones." Xu Dong Hui, a researcher at the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences, said.

　　In terms of management, since 1997, according to the Regulations on Pesticide Management, plant growth regulators have been managed as pesticides.

　　According to the relevant person in charge of the Ministry of Agriculture and Rural Affairs, at present, there are nearly 40 registered plant growth regulators in China. There are more than 100 kinds registered and used internationally. Approved and registered plant growth regulators should formulate technical specifications for safe use, including medication period, dosage, application method, scope of use, matters needing attention and safety interval, and clearly mark them on product labels to guide farmers to use them reasonably. In addition, a series of residue tests should be carried out for registered products, and residue limit standards and reasonable use criteria should be formulated according to data such as residue tests to ensure the quality and safety of agricultural products. Since 2015, the Ministry of Agriculture and Rural Affairs has conducted a risk assessment of plant growth regulator residues in agricultural products, and the results show that the average residue value of plant growth regulators is only 0.001— 0.034 mg/kg, the risk of dietary exposure is very low, and the product quality and safety are guaranteed.

　　Experts said that in terms of safety, there have been no food safety incidents caused by plant growth regulator residues in the world so far. In China, agricultural products that have been applied with plant growth regulators are also very safe for consumers. Compared with other pesticides, although plant growth regulators are included in the management of pesticides, they are not pesticides for treating diseases, insects and weeding in the traditional sense. Their products are of low toxicity, and some of them are even listed as exempted substances without setting residue limits because they are almost nontoxic. For example, the toxicity of chlorfenuron commonly used in expanded fruits (LD50 > 4,918 mg/kg) is lower than that of salt (LD50 = 3,200 mg/kg). In addition, because the amount of plant growth regulator is small, excessive use is easy to produce adverse effects, and farmers can not use it in large quantities, so the residue of plant growth regulator is low.

　　Fruit size is determined by many factors.

　　Then, what factors are related to the size of cherry fruit, and can the swelling agent "double" the fruit?

　　According to experts, large cherry and seedless cherry are related to variety characteristics, cultivation measures and the use of plant growth regulators.

　　Xu Donghui told reporters that "Meizao" is the largest fruit among the cherry varieties at present. This variety of cherries has the characteristics of large fruit shape, full and sweet taste. Under normal circumstances, the single fruit weight of "Meizao" is 8-mdash; 12 grams, which can reach 16-mdash under special cultivation methods; Twenty grams.

　　"A sweet cherry variety selected in China ‘ Red light ’ Under normal circumstances, the weight of a single fruit can reach 11-mdash; Fifteen grams. From the point of view of drug control, it has been reported in literature that treating cherry with plant growth regulator gibberellic acid can increase the weight of single fruit by about 15%— 30%, the swelling effect is limited. " Wang Qiang said.

　　So, does cherry seedless mean that it has been treated with swelling agent? Wang Qiang said, this statement is too absolute. Although it is reported in the literature that cherry stones will be hollow after being treated with gibberellic acid at a certain concentration, it is not necessarily 100% seedless after being treated with gibberellic acid at a low concentration. In addition, the causes of cherry hollowness are natural abortion or other possibilities, not necessarily because of the use of gibberellic acid and other drugs.

　　Xu Donghui explained that in order to improve the pollination rate and fruit setting rate of cherries, fruit farmers will apply gibberellin and other plant growth regulators at flowering stage, which may also cause seedless fruits and nuts, but this will not affect the safety of cherries.

　　Recently, this year’s perfect composition "Living in a Tree" in Zhejiang College Entrance Examination triggered a hot discussion among netizens, and Chen Jianxin, the leader of the composition marking group of Zhejiang College Entrance Examination and an associate professor of Zhejiang University, received attention. Some netizens pointed out that Chen Jianxin was the editor-in-chief of the college entrance examination composition teaching aid book, and gave many lectures on college entrance examination composition teaching, and questioned Chen Jianxin’s "abuse of power for personal gain".

　　In this regard, the survey in The Paper found that Chen Jianxin had edited two supplementary books on composition for college entrance examination in 2016 and 2019, and gave lectures on "Intensive Training Course on Composition for College Entrance Examination" through Tencent Classroom, Qingyun Duan Micro Classroom, Southern Academy and other platforms, with a price of 199 yuan. In addition, he has given many lectures on composition for teachers and students in Zhejiang Province.

　　Is Chen Jianxin’s behavior illegal or "abusing power for personal gain"? When interviewed by The Paper, many education experts said that it is necessary for Zhejiang Education Examinations Institute to answer and decide whether college entrance examination examiners edit relevant books and give lectures in violation of regulations.

　　Recently, The Paper repeatedly called the Scientific Research and Publicity Department of Zhejiang Education Examinations Institute, but no one answered the phone.

　　With regard to a series of discussions triggered by the perfect score composition of Zhejiang college entrance examination, many education experts also mentioned that further education reform should be carried out to change the way of education evaluation.

　　Editor-in-chief of the college entrance examination composition teaching assistant, lecturing on the "intensive training course of college entrance examination composition" for 199 yuan.

　　The Paper noted that Chen Jianxin had participated in the editing of two supplementary books on college entrance examination composition, namely, Selected Comments on Essays published by Zhejiang Education Publishing House in 2016 and Practical Training on College Entrance Examination Composition published in 2019. At present, these two books are sold on multiple e-commerce platforms.

　　In a shop of an e-commerce platform, the introduction of "Selected Comments on Discourse Articles" shows that Chen Jianxin, the editor-in-chief of the book, is priced in 30 yuan, and the content is divided into five parts; The latest revised edition published in 2017 added the "2017 college entrance examination composition marking standard" and "selected more than 20 examination room compositions and authentic comments".

　　According to the information of another store on the above-mentioned e-commerce platform, one of the two editors of the College Entrance Examination Composition Practical Training is Chen Jianxin, whose price is 59 yuan, and the designated purchase method is "Xinhua Bookstore in Zhejiang Province". The book also contains full-score compositions and comments from the college entrance examination.

　　In addition, Chen Jianxin’s "Intensive Training Course of College Entrance Examination Composition" was launched on Tencent Classroom, Qingyun Micro Classroom and other platforms, and was promoted through the media platform in late April 2019.

　　The poster of this course is written with the words "2019 College Entrance Examination Composition" and "College Entrance Examination Composition Intensive Training Course for Candidates by College Entrance Examination Marking Teachers". According to the lecturer, Chen Jianxin has been the leader of the composition marking group of Zhejiang College Entrance Examination since 2000, presiding over the composition marking work of Zhejiang College Entrance Examination every year, and evaluating the perfect composition every year. The introduction of the course features in the poster also emphasizes "the head of the college entrance examination marking team and the famous marking teacher personally teach", "accurately coping with the scoring points of the college entrance examination composition" and "writing skills that can be directly applied to the examination room composition".

　　According to the information in the publicity page, the "2019 College Entrance Examination Composition Intensive Training Course" was created by Zhejiang Education Publishing Group, with a total of 18 sessions, including the college entrance examination composition marking and high score points, examination, conception, breakthrough in essay writing, and the use of words and phrases. The online course is priced at 199 yuan in Tencent classroom and Southern Academy platform.

　　In addition, Chen Jianxin has given lectures on composition for college entrance examination for Zhejiang teachers and students for many times.

　　Official website, Education Bureau of Huzhou City, Zhejiang Province, shows that Chen Jianxin gave a special lecture on composition for the 2019 college entrance examination for all senior high school teachers in Deqing County in March 2019 in Deqing No.1 Middle School of Huzhou. Official website, the People’s Government of Cangnan County, Zhejiang Province, shows that Chen Jianxin participated in the "On-the-spot Meeting of Writing Guidance for Senior High School Chinese College Entrance Examination" hosted by Cangnan County Education Bureau in March 2018, giving lectures on composition guidance for nearly 200 senior high school Chinese teachers. Official website of Hangzhou Xuejun Middle School in Zhejiang Province showed that Chen Jianxin had given a lecture entitled "How to write a good exposition article" at the school in April 2017, and the audience was all senior three students of Hangzhou Xuejun Middle School.

　　On the morning of August 10th, according to the report of The Paper, Chen Jianxin responded that he was "unclear" about compiling teaching AIDS for college entrance examination composition.

　　Whether the relevant behavior is illegal or not needs to be answered by Zhejiang Education Examinations Institute.

　　In the past few days, the concern aroused by the perfect score composition of Zhejiang college entrance examination has shifted from the discussion on the text of Living in a Tree and whether the full score given by the composition is reasonable to the disclosure of the marking situation by the head of the Chinese marking group of the college entrance examination, the editing of the teaching aid book of the college entrance examination composition, and whether the intensive training courses and lectures on the college entrance examination composition are in compliance and whether it is suspected of abusing power for personal gain.

　　In this regard, on August 10th, Chen Zhiwen, editor-in-chief of China Education Online, said in an interview with The Paper that there was no room for discussion about how to judge the perfect composition in Zhejiang College Entrance Examination. "In fact, foreign exams such as TOEFL, IELTS SAT, GRE, etc., candidates need to sign a statement on the transfer of rights before the exam. The core meaning is that right or wrong is determined by the organizers of the exam, not by people including candidates." Chen Zhiwen said.

　　He believes that among the concerns caused by the perfect score composition of Zhejiang college entrance examination, the only point worth discussing is: Who pushed a topic that is not suitable for discussion in the public opinion field to the public opinion field?

　　On August 5th, Wen Rumin, editor-in-chief of Chinese textbooks for primary and secondary schools hired by the Ministry of Education, pointed out in the Weibo that the marking of the college entrance examination should be kept confidential, and all participants in marking should not disclose the marking situation to the outside world, and bluntly said, "It is illegal to disclose the Zhejiang perfect score composition in the journal for the first time."

　　In addition, on August 10th, Chu Zhaohui, a researcher at the Chinese Academy of Educational Sciences, told The Paper that it was definitely not suitable for the group leader of Chinese composition marking in the college entrance examination to write and publish the college entrance examination composition guidance book and give lectures on composition guidance.

　　In this regard, Chen Zhiwen said that, unlike the proposer, the management of college entrance examination examiners is relatively not too confidential. Therefore, whether it is illegal for college entrance examination examiners to go out to give lectures and publish some related books requires the relevant departments of various provinces to answer and decide.

　　Similarly, Xiong Bingqi, president of the 21st Century Education Research Institute, pointed out that it is not rational to discuss the issue just because Chen Jianxin published books and participated in lectures. Whether there is any act of illegally seeking personal gain by using the identity of the group leader of Chinese composition marking in Chen Jianxin requires the involvement of relevant departments in the investigation.

　　An education expert who did not want to be named bluntly said: "Zhejiang Education Examinations Institute has the responsibility to stand up and respond to public questions."

　　Expert: The entrance examination should be changed from "selection" to "evaluation"

　　Xiong Bingqi believes that it is impossible for the examiners to disclose the college entrance examination questions, and it is not against the regulations to interpret the marking standards for serving candidates, with the leader of the marking group as the editor-in-chief and publishing books on composition guidance.

　　Chu Zhaohui, on the other hand, said that Chen Jianxin is not alone in publishing books and giving lectures by examiners in the college entrance examination. Some training institutions still use examiners to conduct commercial speculation. He believes that this kind of situation has both loopholes in the system and lax management, so it is necessary to improve the system and strengthen management.

　　In addition, Chen Zhiwen believes that the statement that "Chen Jianxin has been the head of the Zhejiang College Entrance Examination Chinese composition marking group since 2000 and presided over the annual Zhejiang College Entrance Examination composition marking work" needs to be verified by the authorities. "There are still many people who claim to be the leader of the proposition, or the proposer. Can you believe it?" Chen Zhiwen said.

　　Talking about a series of discussions triggered by the perfect score composition of Zhejiang College Entrance Examination, Chu Zhaohui and Xiong Bingqi both mentioned the need for further education reform.

　　Xiong Bingqi pointed out that the focus of the contradiction lies in the fact that the college entrance examination is a selection test, not an evaluation test. The so-called selection test is to select candidates fairly, and it doesn’t matter whether the selection system is scientific or not; The evaluation test, on the other hand, is to pass the test to evaluate students’ mastery of real subject knowledge and subject accomplishment.

　　He believes that it is difficult to solve the problem of exam-oriented composition atmosphere through marking. "To improve the quality of composition proposition and reading, further improve the quality of Chinese education, and the quality of education in all subjects, we need to promote the reform of the examination enrollment system and effectively change the entrance examination from ‘ Selection ’ , the reform is ‘ Evaluation ’ . Otherwise, the controversy surrounding the proposition and marking is just ‘ Chicken feathers in one place ’ 。”

　　Chu Zhaohui believes that the controversial issue reflects from a deeper level that the current enrollment examination program design is not standardized and professional. "In a more standardized and professional procedure, the questioner doesn’t have to write the questions in a closed environment, and the questions need to go through multiple procedures and various tests before ‘ Out of the oven ’ ; In the marking session, it will not be determined that a certain person will be the team leader for a long time. " Chu Zhaohui said.

　　"There is still a long distance between the professionalism and modernity of the college entrance examination enrollment process and modern education evaluation." Chu Zhaohui, for example, said that some foreign exams judged that candidates cheated, not because they caught the candidates plagiarizing in the examination room, but because they initiated the analysis of the answer results, and if the analysis results showed that some answers reached a certain similarity, they were considered cheating.

　　In this regard, Chu Zhaohui’s idea can allow ordinary colleges and universities to use students’ academic performance in high school as the basis for enrollment, thus narrowing the scope of the college entrance examination. In this way, the workload of marking and evaluating the college entrance examination is relatively reduced, and it is possible to analyze and evaluate the results of the college entrance examination according to different levels, to reverse the problems of exam-oriented teaching and routine answering, and to promote the specialization and modernization of educational evaluation.

　　In the 2008 Beijing Olympic Games, Phelps’ eight gold medals broke the 36-year-old record that was once considered inaccessible by swimmer Mark Spitz. Phelps participated in men’s 400m individual medley, men’s 200m individual medley, men’s 100m butterfly, men’s 200m butterfly, men’s 200m freestyle, men’s 4x100m freestyle relay, men’s 4x200m freestyle relay and men’s 4x100m medley relay successively at the Beijing Olympic Games, winning eight gold medals, breaking seven world records, and gaining fourteen individual medals.

　　BEIJING, Aug. 16 (Xinhua) Title: Swimming Inventory: The United States and Australia are "gender imbalance" and the China Navy is no longer "water"

　　Author: Lu Chunyan

　　On August 17th, "prodigy" michael phelps led the American team to win the gold medal in the men’s 4×100 medley relay final, and won his eighth gold medal in Beijing. This marks the end of the swimming event in Beijing, which is second only to the 46 gold medals in track and field. The "Water Cube" of this Olympic Games has turned into a "Water Cube", and the world record has been labeled as "fragile". The United States and Australia have their own gains in competing for hegemony, and the China Navy has also seen hope in its progress.

　　"Yang Prosperity and Yin Decline" VS "Yin Prosperity and Yang Decline" The United States and Australia strive for hegemony and "gender imbalance"

　　Compared with the Athens swimming event, the gorgeous performance of the American swimming team in the Water Cube can be described as "dominating the world". The results of 12 gold medals, 9 silver medals and 9 bronze medals left Australia’s 6 gold medals, 6 silver medals and 8 bronze medals far behind.

　　However, Australia, suppressed by the United States, should also be respected. After all, today’s swimming world has the strength to challenge the American team, and it is Australia. The remaining 14 gold medals were divided among 11 countries, with Britain, Germany and Japan each taking two, and China, Brazil, Tunisia, South Korea, the Netherlands, Italy, France and Zimbabwe each taking one.

　　The distribution of gold medals in the American swimming delegation showed a situation of "Yang flourishes and Yin declines". Male athletes won 10 of the 12 gold medals, and they monopolized five-eighths of the Olympic men’s swimming events under the leadership of Phelps. Only coughlin and Sony saved a little face for American female swimmers.

　　Unlike the United States, which relies on men’s events, Australia has completely embarked on the "female route". All six gold medals in the "Water Cube" were won by female athletes, while male athletes only got three silver medals and three bronze medals. Compared with the American team, Australia’s "Yin flourishes while Yang declines" seems to be more thorough.

　　"Yin flourishes and Yang declines" VS "Yang flourishes and Yin declines", and there is a gender imbalance between the United States and Australia. In August, a gender war was staged at the National Aquatics Center.

　　World records are labeled as "fragile" and old records are turned into rarities.

　　The Water Cube staged a "war epic" against the "world record" from the first match day when two world records were born in the four finals. Seven of the eight gold medals won by the American "prodigy" rewrote the world record, and even the only gold medal in the 100m butterfly, which was "lighter" than the other seven gold medals, was almost the same as the world record. What’s more, Zimbabwe’s Coventry started a record-breaking trip in the preliminaries.

　　The birth of one new world record after another makes the audience seem to have formed "aesthetic fatigue" on the records, and a large number of newly released records really test everyone’s memory. All of a sudden, those records that have been preserved have become rare, and they can still be "immune" when such large-scale good results are released, which shows the preciousness of these old records.

　　Men make history. China swims in the "Water Cube" and sees hope.

　　China swimming, dormant in the downturn, finally saw the hope of recovery in the "Water Cube". One gold, three silvers, two bronzes, three 4th, one 5th, one 7th and one 8th in this Olympic Games are enough for China to get a performance score of 80 points. All these have become the best evidence that Zhang Yadong, the head coach, pointed out that China Water Army began to walk out of the trough.

　　Liu Zige, Jiao Liuyang and other young players have changed the situation in 2007, and Zhang Lin’s silver medal has also shown us the progress of male athletes.

　　The most significant one is the silver medal in the men’s 400-meter freestyle from Zhang Lin. Even in Barcelona, the most splendid swimming place in China, the male swimmers from China failed to grab a gold and a half silver. Zhang Lin won the first medal in Olympic history for men’s swimming in China with his own efforts and national support.

　　However, we should also see that China’s swimming strength is still far from the collective advantage of the United States and Australia, and the highlights are only concentrated in three or two events. Moreover, China’s swimming does not have the domineering and winning strength of the United States and Australia.

　　However, I still believe that "a single spark can start a prairie fire", and I hope that China Swimming, which finds a breakthrough point, can make a name for itself in the Olympic swimming field through its own efforts.

　　"God" Phelps, the first man in the centennial Olympic Games, ascended the throne in Beijing.

　　After winning the NBA championship three times in a row, the media commented that "Jordan is God wearing a jersey and playing"; Once again won the NBA championship for three consecutive times, the media commented that "even God can’t beat Jordan in his jersey". Therefore, even with bare arms, God may not be able to win eight gold medals in an Olympic Games, but the "prodigy" did it.

　　Michael phelps seems to have come to Beijing to break the record. He has seven world records in eight competitions, a single Olympic gold medal record with eight gold medals and an individual Olympic gold medal record with fourteen gold medals. Phelps is proving himself to be the "Water Cube" and the king of Olympic history with figures that others can’t match.

　　When Bolt broke the world record and won the 100-meter new Olympic champion, the media who liked the new and hated the old questioned the ownership of "the best athlete in Beijing Olympic Games". In fact, this is a very simple arithmetic problem. Can’t nine records beat one record? The record of eight gold medals of "prodigy" was accumulated in the Olympic Games for a hundred years, but who can say that the record road of 9.69 seconds can be kept fresh in a hundred years?

　　For 23-year-old Phelps, the Beijing Olympic Games is probably just a "walk" of his brilliant career, because he will be 27 years old in four years, which is the best age for professional athletes. At that time, he will give the world the expectation of several Olympic gold medals. (End)
