From the perspective of accelerating the construction of China’s modern university system, it has become an urgent issue that cannot be avoided in the healthy development of China’s higher education to re-examine the ethical relationship between teachers and students.

　　The roles between teachers and students in colleges and universities are not equal. Even if the relationship between teachers and students is pure, it will undermine fair competition, which is not in line with the principle of interest avoidance in the modern university system.

　　It is also in line with the basic principles of professional ethics to prohibit the love between teachers and students. This means that if you choose a teacher as a profession, you should give up some aspects of freedom.

　　Should other forms of relationships beyond teachers and students be allowed on campus?

　　In 2010, the General Office of the State Council issued the Notice on Launching the Pilot Reform of the National Education System, which clarified the reform task of establishing a modern university system. The author finds that bringing the connotation and extension of modern university system into operation under the national conditions of China will inevitably face various obstacles and contradictions. Among them, the enrollment corruption, academic misconduct and the scandal between teachers and students are some realistic problems with great negative influence, and they are also urgent problems that must be solved in building a modern university system in China. For the latter, because it will involve sex, extramarital love and family conflicts, stimulating and challenging China’s traditional family ethics will often become the focus of public opinion and news media.

　　Especially in recent years, some well-known universities in China have frequently exposed the scandals of teachers and students. For example, a male professor of a university in Xiamen was reported to have been photographed half naked by students, and Professor jane doe was reported to have seduced his doctoral students. An associate professor at a university in Beijing was reported for having sex with female students; Long-term sexual abuse of female students by the vice president of a university in Shanghai was reported … … Similar cases occur frequently, and the list is endless.

　　The author sorts out some incidents in recent years and finds that the love between teachers and students is mostly due to conflicts such as interest disputes, emotional deception, family disputes, etc., and finally it is made public in the form of revelations, reports and sex scandals. One of the worst cases is that some teachers with corrupt moral character have sex with students through deception, hidden marriage, and even coercion and inducement, which has a very serious impact and consequences.

　　This kind of phenomenon has a bad influence on the reputation of colleges and universities, which greatly worsens the public’s perception of college teachers. There are even various malicious banter words such as "calling animals" instead of "professors" in society. The "rat excrement" effect of sex scandals in colleges and universities makes university teachers, who were originally intellectuals and shouldered the heavy responsibility of educating and educating people for the country, lose their dignity and reputation.

　　Therefore, from the perspective of accelerating the construction of China’s modern university system, it has become an urgent issue that cannot be avoided in the healthy development of higher education in China to re-examine the ethical relationship between teachers and students in universities, especially how to regulate and restrain the abnormal emotional and sexual relations between teachers and students on campus.

　　Under the modern university system, should the university campus allow other forms of relationship between teachers and students beyond teachers and students?

　　"Teachers and students can’t fall in love" is a well-known common sense in American universities.

　　We might as well look at how foreign universities view and deal with this problem.

　　Before the 1980s, there were no explicit provisions or restrictions on the emotional or other relationships between teachers and students in the teachers’ codes of American universities. However, in 1983, the dean of the School of Arts and Sciences of Harvard University publicly pointed out that the romantic relationship between teachers and students was wrong, which aroused a great discussion on this ethical relationship between teachers and students in the educational circles, feminist organizations and judicial circles in the United States. In 1984, Harvard University was the first to issue a ban on romantic relationships between professors (including their student assistants) and their direct students. In 1986, the University of Iowa also stipulated that professors were not allowed to have romantic relationships with students who were taking their own classes or guiding themselves. However, if students do not attend the professor’s class and are not the students instructed by the professor, this relationship can also be acquiesced.

　　This management mode of Harvard and the University of Iowa became the main mode for American universities to standardize the management of similar ethical relations between teachers and students in the 1980s and 1990s. Until 2001, a teacher at William and Mary College in Virginia revealed her love story with a married student, which caused a great sensation in the United States. This incident forced nine universities in California to jointly revise the teachers’ code and introduce stricter regulations, prohibiting all teachers and students from having any other relationship beyond the teacher-student relationship. This is the first time in American universities that teachers and students who have no direct guidance relationship can’t fall in love. The ban points out that no matter whether teachers are married or unmarried, they are not allowed to have a relationship with students. If there is a love affair, one of the parties must choose to leave school voluntarily — — Teachers leave or students drop out of school.

　　In practice, because teachers are on the power side, once this relationship between teachers and students is made public, schools often punish teachers instead of students. With few exceptions, any teacher who has this relationship will be fired or expelled once he is found out. At present, this code has been adopted by most American universities, especially famous private universities.

　　After more than 30 years of constant debate and revision, it is now a common sense that "teachers and students can’t fall in love" in American colleges and universities.

　　Japan is a relatively open country, but the requirements and supervision of university teachers are very strict. In Japan, the relationship between teachers and students is very sensitive. Once the abnormal relationship between teachers and students is found, the parties will face severe punishment, and students will not dare to sacrifice their reputation to have intimate relations with teachers. In 1993, Professor Kyono Chang of Kyoto University was forced to quit his teaching post because of the affair of sex, and went to Tofuku-ji Temple, the capital of Kyoto, to practice, and was soon expelled from the temple. In 1996, he had to leave Japan and was abandoned by Japanese society. In 1999, he died in another country, with a miserable end.

　　In Britain, due to many sexual harassment incidents on campus, in 2007, many universities stipulated that teachers should report to the school if they fall in love with students, so as to prevent teachers from "favoritism" or sexually harassing students.

　　In Germany, although there is no special law explicitly prohibiting the love between teachers and students in colleges and universities, the so-called love between teachers and students or similar relationship beyond teaching and learning will not only be condemned by morality, but also violate the professional standards of teachers. Especially in recent years, with the younger teachers in Germany and the increasingly precocious students, teacher-student love and other events that are not in proper relationship, the relevant German institutions have begun to appeal in the Federal Parliament to draft special laws as soon as possible to prohibit teachers from having love relationships and sexual behaviors with students.

　　It can be seen that some countries, such as Japan and the United States, have strict control over teachers and students’ feelings beyond teachers and students or proper relationship.

　　The "Red Seven Articles" in colleges and universities should explicitly prohibit any form of teacher-student love.

　　The author believes that on the basis of learning from foreign experience, it is necessary to carefully examine and sort out the new ethical relationship between teachers and students in modern university campuses, make detailed definitions and norms, and introduce relevant measures and management methods.

　　Traditionally speaking, China has been a country that respects teachers and values education since ancient times. It has the traditional thought of "learning to be a teacher and being a model", and even more, it has the ethical concept of "being a teacher for a day and being a father for life". It is these cultures that are deeply rooted in people’s hearts that make teachers a noble and sacred profession, and also have higher expectations and requirements for teachers’ ethics.

　　In 2014, the General Secretary of the Supreme Leader emphasized at the Teachers’ Day Symposium of Beijing Normal University: "A qualified teacher should first be morally qualified, and a good teacher should first be a model of teaching and standing by virtue. We must actively guide the majority of college teachers to be good teachers who are satisfied with the party and the people with ideals and beliefs, moral sentiments, solid knowledge and kindness. "

　　In response to the call, the Ministry of Education immediately issued the "Opinions on Establishing and Perfecting the Long-term Mechanism of Teachers’ Morality Construction in Colleges and Universities", and drew out the "Red Seven Articles" of teachers’ morality prohibition behaviors that have warning and educational significance for college teachers. Article 7 clearly stipulates: "Sexual harassment of students or proper relationship with students, and other behaviors that violate the professional ethics of college teachers are strictly prohibited." The author believes that the "Red Seven Articles" is of milestone significance for standardizing the ethical relationship between teachers and students in colleges and universities under the modern university system and building teachers’ ethics in colleges and universities.

　　The launch of the "Red Seven Articles" in colleges and universities is just the right time, especially the seventh article, which sets a circle and rules for establishing the normal ethical relationship between teachers and students in colleges and universities. Here, the author also wants to put forward specific suggestions on article 7 from the implementation level:

　　On the one hand, it is necessary to explicitly prohibit any form of college teacher-student love.

　　One view is that teachers and students in colleges and universities are adults, and there is no identity problem. It is normal for teachers and students to fall in love freely. China’s cultural tradition holds a favorable or tolerant attitude towards other forms of relations between teachers and students in colleges and universities that surpass teachers and students. Tracing back to the Republic of China, there are many literary stories in which teachers and students such as Lu Xun and Xu Guangping, Qu Qiubai and Yang Zhihua, Shen Congwen and Zhang Zhaohe fell in love and got married. In 2014, the media reported that a senior student of a university in Jilin successfully proposed marriage to a university teacher who had been in love for three years, and public opinion was full of support and praise.

　　In fact, from the perspective of ethics, in addition to the traditional basic relationship between teachers and students, in the modern university system, emotional and even sexual relations between teachers and students have become more and more sensitive in the ethical relationship between teachers and students. Because it is difficult to define, standardize and deal with, it forms a vague area in people’s understanding and also causes great controversy.

　　In my opinion, although college students are adults, their world outlook, outlook on life and values are still in a critical period of formation, and their minds are not fully mature, so the love between teachers and students is hardly pure love. What is important is that the roles between teachers and students in colleges and universities are not equal, and there are relationships in management, power and interests. Even if teachers and students are pure emotional relationships, this relationship will undermine fair competition and does not conform to the principle of interest avoidance in the modern university system.

　　It is also in line with the basic principles of professional ethics to prohibit the love between teachers and students. Just like doctors and patients, lawyers and clients, priests and church members can’t fall in love or have sexual relations, the requirements of teacher-student relationship should also be in line with these occupations. This means that if you choose a teacher as a career, you should give up some aspects of freedom.

　　On the other hand, strengthen the supervision and management of the ethical relationship between teachers and students in colleges and universities, and strengthen the accountability of those who touch the red line. According to the author’s observation, in recent years, the relevant units have been excessively lenient in dealing with the exposed peach affair and sex scandal. After the incident is exposed, the radish is often pulled out and the mud is brought up. With other lesions such as academic misconduct and misappropriation of funds, the units involved classify emotional and sexual relations as private morality and pay insufficient attention to them. Often, the board is held high and gently put down. In particular, some people involved in the case have certain academic attainments, titles and hats, and the units concerned even use the excuse of cherishing talents and rare talents to minimize major issues and avoid troubles. What’s more, some parties can continue to stay in the teaching staff by changing units, which is not affected at all.

　　In addition, the relevant accountability means are not clear and specific enough. It can be seen from the handling results of several incidents exposed on the Internet that it is difficult to find relevant basis and clear explanation for the handling and punishment of teachers and students who are not proper relationship, and even the Red Seven Articles have not given specific disciplinary measures and measures; As a weak group, it is difficult for students to find effective complaint channels and departments after the incident, and their interests cannot be protected. In the end, they can only be exposed on the Internet, forming a whirlpool of public opinion. This also shows that the supervision responsibility of discipline supervision units in some units is not in place, and discipline is lost.

　　China’s higher education is in the process of all-round modernization, and many universities are drafting university statutes to establish a modern university system. The author hereby appeals that we should start with standardizing and reconstructing the ethics of teachers and students in colleges and universities, seriously consider and sort out how to establish a healthy and good relationship between teachers and students under the modern university system, unify our thinking and understanding, and pay more attention to the frequent campus peach scandals in recent years, and increase the handling and punishment. By establishing rules and regulations, prevention comes first, and the campus atmosphere is further purified, creating a clean environment for the healthy growth of students and escorting the training of young talents.

　　CCTV News:According to the website of the Central Meteorological Observatory, in the past day, due to the influence of the "saddle" residual cloud system, heavy rains occurred in parts of southwestern Guangdong, central and southern Guangxi, western and southern Yunnan, and heavy rains (100 ~ 194 mm) occurred in Maoming and Zhanjiang in Guangdong, Xishuangbanna and Pu’ er in Yunnan; There are 6 ~ 8 gusts in some of the above areas, and the local level is 9 ~ 10. At present, the influence of "saddle" on China has basically ended.

　　In the next ten days, the West China region will enter a rainy period, and the accumulated rainfall will turn from significantly less in the previous period to more. It is estimated that from 27th to 30th, there will be a round of heavy rainfall in the area from West China to Huanghuai, with moderate to heavy rain in the eastern part of Northwest China, the eastern part of Southwest China, southern North China, Huanghuai, Jianghan, Jianghuai and other places, and heavy rain in parts of Shaanxi, southwestern Shanxi, western and northern Sichuan Basin, northern Henan and other places. Some of the above areas are accompanied by strong convective weather such as short-term heavy precipitation and local thunderstorms and strong winds.

　　Among them, from the 27th to the 28th, the rainfall will mainly appear in the eastern part of northwest China and the southern part of North China; From the night of 28th to 29th, the main rain area moved to the south of Shaanxi, the north and west of Sichuan Basin and the north of Chongqing. In addition, there will be obvious rainfall in Huanghuai, Jianghan and Jianghuai from the night of 28th to 30th.

　　Meteorologists reminded that the rainfall process lasted for a long time and the local accumulated rainfall was large. Southwest Shaanxi, Gansu, Sichuan, Chongqing and other places need to guard against the sharp turn of drought and flood. The public should pay attention to preventing urban and rural accumulation and flash floods and geological disasters that may be caused by local heavy rainfall or continuous rainfall.

　　In terms of high temperature, in the past day, some areas in Sichuan Basin, central Hunan, central and northern Jiangxi, southern Zhejiang and northern Fujian experienced high temperature above 37℃, and the highest temperatures in Beibei, Chongqing and Fengjie, and Fuzhou, Fujian reached 40 ~ 40.7℃.

　　At present, the range and intensity of high temperature in the south are gradually shrinking, and the high temperature warning was downgraded to yellow on the evening of 26th. Affected by the strong rainfall process, the high temperature will further subside in the future: it is expected that the high temperature in Sichuan Basin, Chongqing and other places will weaken and end on the 29th, and the high temperature in most parts of the south of the Yangtze River will also subside on the 31st, and the continuous high temperature weather process in the south will end.

　　The Central Meteorological Observatory continued to issue a yellow warning of high temperature this morning: during the day, there are high temperature weather of 35 ~ 39℃ in eastern Sichuan, Chongqing, northern and eastern Guizhou, southern Hubei, Hunan, Jiangxi, southern Zhejiang, Fujian, central and northern Guangdong, and northwestern Guangxi, among which the highest temperature in parts of western and northern Chongqing can reach above 40℃. The public should take measures to prevent heatstroke and cool down, and pay attention to the safety of electricity use indoors.

CCTV News:China — The Central Asia Summit was successfully held in Xi ‘an. The heads of government departments of Central Asian countries attending the meeting positively evaluated the important role of the Summit in promoting regional peace and development, and highly affirmed China’s promotion of the construction of China — Central Asia’s community of destiny and efforts to achieve common development with all parties.

Minister of Foreign Affairs of Tajikistan Mukhriddin:This summit is dedicated to building China — Central Asia’s community of destiny will have a far-reaching and comprehensive impact on the whole region. We appreciate this concept put forward by China very much, which reflects our commitment to win-win cooperation and common development. In addition, the global development initiative, global security initiative and global civilization initiative put forward by China leaders are of great significance to all countries.

Minister of Economy and Commerce of Kyrgyzstan Daniar Oman Geldyev:The "One Belt, One Road" initiative put forward by Chairman of the Supreme Leader unites all of us. This year marks the 10th anniversary of the initiative. I think we have made great achievements in the past 10 years. For our landlocked countries, the "Belt and Road Initiative" has helped the whole Central Asian region gain the potential for economic and trade development. China — The Central Asia Summit will bring broad prospects for cooperation and development in Central Asia.

During the summit, many countries in Central Asia signed cooperation agreements with China in energy, economy, trade, humanities, science and technology and other fields. The participants are looking forward to being in China — Under the Central Asia mechanism, we will further deepen pragmatic cooperation in various fields and make the results more beneficial to the people in the region.

Jurabek Mi Erzha Makhmudov, Minister of Energy of Uzbekistan:Under the framework of this visit, we signed a series of solid cooperation agreements and memorandums, and reached cooperation intentions on projects in renewable energy and other fields. These projects will not only help the development of Uzbekistan, but also promote cooperation among all countries in the region. We look forward to further deepening cooperation with China in various fields.

"Ali Farabbi" Tuimebayev Jansen CancentToure, President of Kazakhstan National University;Our university and Northwestern Polytechnical University signed a cooperation agreement under the witness of the two heads of state. This is the first time that a China university has set up a branch school in Kazakhstan. We believe in China — The Central Asia Summit will further promote exchanges and cooperation between Central Asian countries and China in the fields of education, science and technology. Especially in the current complicated international situation, the convening of the summit is of great significance to promoting peace and stability in Central Asia and even the world.

　　According to the monthly climate report released by the National Oceanic and Atmospheric Administration on September 14th, according to the data so far this year, there is a 93.42% probability that 2023 will become the hottest year on record.

　　For many people, this summer seems to be particularly long and unbearable. In the past few months, rare high temperatures above 40℃ have continued to appear in many places in China, followed by heavy rainfall and floods; Globally, many countries in South Asia and Southeast Asia ushered in extreme heat waves early in April-May; Mountain fires raged in Canada and Hawaii in the United States, and the casualties were the highest on record; The abnormal warming of seawater around Britain and Ireland threatens the survival of fish … …

　　However, this summer’s extreme weather may be just a preview of the future. In fact, the summer in the northern hemisphere is indeed extending. A study published in Geophysical Research Letters shows that if no measures are taken to curb global warming, by 2100, the northern hemisphere will spend more than half of its time in summer every year. The extended summer will not only bring longer high temperature, but also witness more extreme weather events such as rainstorm and mountain fire, which will also bring severe tests to phenology and agriculture.

　　"If the trend of global warming is not contained, the climate model forecast shows that there is the possibility that winter will disappear at some time in the future." Guan Yuping, a professor at south china sea institute of oceanology, told The Paper, "It’s hard to imagine what the earth will be like then!"

　　"Arrive early and leave late" in summer

　　Guan Yuping and his collaborators did this research by accident and curiosity, but the "unexpected" discovery attracted the attention of the whole world.

　　In this study, they analyzed the climate data of the northern hemisphere from 1952 to 2011 and found that the average length of summer has increased from 78 days to 95 days under the influence of global warming. If no measures are taken under the current greenhouse gas emission, by 2100, the summer in the northern hemisphere will be as long as six months, and the length of the other three seasons will be shortened.

　　And this summer’s high temperature "early arrival and late departure" is confirming this trend.

　　As early as the beginning of April, record extreme high temperatures appeared in Southeast Asia and South Asia. At the end of April, the temperature in southwest Europe and North Africa was 20℃ higher than the normal level in the same period of last year, reaching the high temperature level that is usually only available in July and August. Subsequently, new records of high temperature emerged one after another, and many authoritative organizations announced that July this year has become the hottest month on record on earth.

　　Until the end of August, 28 provinces in France still issued orange heat wave warnings, the temperature in some parts of the Middle East exceeded 50℃, and the high temperature record in central America was still being refreshed … …

　　In addition to the high temperature, this summer’s unusual extreme weather events such as hurricanes, mountain fires and droughts have also brought unprecedented damage.

　　This summer, after the continuous extreme high temperature in North China, the Haihe River Basin experienced the heaviest rainfall and the biggest flood in 60 years. The rapid transformation of drought and flood has not only broken people’s conventional understanding of the weather, but also made disaster prevention and emergency prevention more complicated.

　　In May, the first residents in Canada were forced to evacuate due to mountain fires. As of August 19th, there were still more than 1,000 mountain fires burning continuously, and they suffered the "worst" forest fire season in history. In the middle and late July, more than a thousand wildfires occurred in many places in Greece, causing air pollution equivalent to consuming 2.3 million barrels of oil; On August 15th, a mountain fire swept through Maui, Hawaii, USA. The worst mountain fire in the United States for more than a century caused 114 deaths and thousands of people lost contact, and the historic town of Lahaina was reduced to ashes … …

　　Premature continuous high temperature may be disastrous for human beings, animals and plants. The latest assessment of the United Nations Intergovernmental Panel on Climate Change (IPCC) shows that compared with before the industrial revolution, global warming of 1.5℃ will bring irreversible impacts on human beings and natural systems. As the global average temperature continues to rise, summer will start earlier and last longer, and the frequency of extreme weather events will also increase.

　　Phenology: biological rhythm that is no longer punctual

　　Abnormal seasonal changes and temperature changes also have a direct impact on biological rhythm. Flowering, Reproduction and Migration … … Everything in nature operates in an orderly way according to phenology, and climate change is disrupting this biological clock that has been calibrated in the past centuries of biological evolution.

　　The United Nations Environment Programme’s Frontier Report 2022: Noise, Fire and Phenology Mismatch points out that under climate change, not all species can evolve in the same direction and at the same rate. It is this mismatch that has a profound impact on the survival of species, and many species will become extinct.

　　A study published in the Proceedings of the National Academy of Sciences shows that global warming is making the spring in North America start earlier and earlier. Birds can’t keep up with this change, and if they deviate from the best breeding time, they will miss the most abundant opportunity in their habitat, resulting in fewer young birds.

　　In America and the Middle East, record warm winters disrupt the hibernation cycle of bears. Walking in the forest in winter, they not only face food shortage, but also pose a threat to the safety of surrounding residents and forestry workers.

　　The extension of summer caused by global warming has also contributed to the spread of infectious diseases. Studies have shown that when the water temperature rises, the time from egg to adult can be shortened from two weeks to one week; When the temperature reaches 26℃ to 31℃, the replication of Japanese encephalitis virus and dengue virus in mosquitoes increases compared with 20℃, and their infectivity is enhanced.

　　In fact, this effect is already happening. So far this year, more than 3 million cases of dengue fever have been reported in America alone. Dengue fever is spreading to areas where Aedes aegypti would not have entered. In 2015, Mexico City at an altitude of 2,240 meters recorded the invasion of Aedes aegypti for the first time.

　　The damage of sewage system and the interruption of drinking water caused by extreme weather events such as hurricanes, rainstorms and floods will also increase the risk of various pathogens. At present, driven by the unusually warm ocean, the hurricane season in the Atlantic Ocean has just begun to "wake up". On August 20th, California, usually unaffected by hurricanes, issued its first hurricane warning in 84 years.

　　Agriculture: Race against Climate Change

　　"Many farmers have reported that it is getting hotter and hotter now, or it is very hot early in the morning." Feng Qihua, a researcher on the impact of climate change on ecological small farmers, told The Paper, "For example, farmers in Pinggu, Beijing, had to cover themselves with quilts in the mountains at the beginning of June last year, but it was already too hot in June this year."

　　In order to investigate the impact of climate change and the accompanying abnormal weather, Feng Qihua and his colleagues visited 18 farms in Beijing, Tianjin and Hebei and South China from May 2022, and interviewed 28 ecological small farmers.

　　During her visit, she learned that due to the extreme high temperature in summer, many farmers had to change their working hours and go to work in the fields before 8 am and after 5 or 6 pm.

　　"(We) are racing against the speed of climate change now." She described it.

　　In addition, some farmers found that when winter is too warm or short, the base of overwintering pests increases, and abnormal temperature or precipitation changes break the population balance of pests and beneficial insects in the soil, so crops will be more susceptible to pests and diseases in spring.

　　However, in Feng Qihua’s view, the greatest impact on agricultural production is not the high temperature and summer extension itself, but the high uncertainty of seasonal change and extreme weather events. "The biggest problem with climate change is that the speed of warming is beyond the range that some systems can bear."

　　This not only means that it is difficult for farmers to arrange production according to the original traditional solar terms and phenological signals, but also means that crops are more likely to reduce production or commodity.

　　"If it is a natural climate change, time will usually happen slowly in hundreds of thousands of years, and animals and plants can often adapt to the environment or move to places suitable for survival, but now the speed of climate change caused by human beings is more than 100 years, which makes them far away ‘ Can’t keep up with the pace ’ 。” She said.
