2023年英语四六级作文10篇预测押题01、作文题目：节食Students, especially girls, often like to lose weight by eating less or taking different kinds of medicine. Dieting has become an obsession for some people. What is your opinion about this obsession with dieting?作文范文：Preventing an Obsession with DietingI believe the craving some young women have to copy what is promoted as the ideal figure for a woman is the cause of their obsession with excessive dieting. A great deal of media advertising makes use of young, slim, attractive women and it is understandably natural that some women want to copy what they see as the ideal role model.Obsessive dieting certainly does happen, as is illustrated by the numerous articles in magazines about people suffering from anorexia. Almost exclusively, this obsession relates to younger women who are constantly bombarded with the supposedly ideal woman as depicted in women's fashion magazines, Most of these fashion models are very slim, some of them excessively so. There is nothing wrong with a sensible controlled diet aimed at losing some excess weight but, when the need to diet becomes an all consuming passions, that is when the danger occurs. Often, the people who become susceptible to the lure of the "perfect" figure are not aware of what is happening to them. Usually, preventing dieting becoming an obsession will depend on friends and relatives recognizing the warning signs. As for preventing the basic cause of this problem, that is a much more complex issue as it involves the standard mores of the society and people being aware of their responsibilities. Education about the dangers of excessive dieting needs to be part of the solution for prevention.In conclusion, an obsession with dieting can be prevented by friends and relativ es of the dieter as well as an education campaign about the dangers of excessive dieting. (261 words)02、题目：考试作弊Cheating in exams is rampant in universities and is considered a major problem. What's your opinion on cheating in exams?写作范文：Cheating in Exams Leads to a Loss of IntegrityIn my opinion, cheating in an exam is a matter of one's integrity. It is easy to be dishonest and deceive other people but it is much harder to deceive one's self. A person who cheats knows they are doing the wrong thing and, as such, it is a reflection on theircharacter.One reason why I, personally, do not advocate cheating is that I would lose my sense of self-respect. To me, my integrity is too valuable to risks the damage that would be caused if I were to cheat. Apart from the fact that I would know I had done the wrong thing, it would generate a concern about being found out. Another consequence of cheating is that it proves one has not acquired the knowledge necessary to warrant the qualification sought. If the cheating results in being awarded a certificate, to me, that certificate would represent a constant reminder of the stain on my integrity.In the final analysis, cheating comes down toll one's character and the degree of self-respect you have. I prefer to earn what I want based on my own ability and efforts rather than become a second-rate person by cheating. (197 words)03、题目：要让每个学生都接受高等教育吗？Some people believe that college or university education should be available to all students. Other people take the view that higher education should be available only to good students. What is your opinion?写作范文：University Education Should Be Available for AllMany people propose the idea that higher education should be available to only qualified students-students with certain aptitudes, who have achieved an excellent academic performance. However beg to differ for the following reasons.To begin with, the general level of education nationwide has always been employed as a criterion to gauge how advanced or developed a society is. In an ideal egalitarian society, everyone should be able to receive higher education unless he willingly forgoes that option. In other words, education should not be viewed as a privilege enjoyed only by people who are endowed with certain talents. Furthermore, it would be tremendously beneficial to any society if the general public6 rather than the fortunate few can enjoy higher education. A wide range of social issues can be effectively remedied by a high-quality education which imparts crucial moral principles. In addition, a great amount of economic value can be generated if higher education is available to more people. Yet, I also concede that it may not be practical or realistic to provide higher education to everyone owing to limited financial as well as human resources. Not even the most affluent nation in the world can fulfill that objective at this stage.In the final analysis, I believe that the more people who can receive higher education, the better off a society will be. (225 words).04、写作题目：现代社会中的女性Women are playing an increasingly important role in society today. With the changes in their social role, women's position in the family has been improved as well. In spite of these changes, the liberation of women has not been completely realised. What is your o pinion on women's role in the modem world?写作范文：More Rights for WomenThroughout history, women have always aimed for a recognized place in society. China is no exception. From the age of foot binding to modernization today, the role and rights of women have undergone a drastic transformation. In my opinion, women should be treated equally and given more rights.Firstly, women have equality in education, marriage, rights, and freedom by law. On founding of the People's Republic of China in 1949, the Communist Party of China declared that women shall enjoy equal rights with men in political, economic, cultural, educational and social life. Historically, women have always been considered as inferior creatures both intellectually and physically to men. There has always been a stereotype that "a woman's place is in the home. Expected to be caregivers, women generally have had fewer legal rights and career opportunities than men. Since it is written in law, women's rights and interests should be protected and gender equality should be guaranteed. Secondly, given the great contributions women are making to society, women's role should be given full play. In China, women account for more than 60 percent of the rural lab our force and are a major force in farming activities, Furthermore, women's role in educating their children and supporting the whole family is also vital to maintain a well-balanced society.To conclude, though China may have taken great leaps forward in official statutes and public pronouncements concerning women, nonetheless, in practice, backed by centuries of history and tradition, the old ways die hard. Therefore, more efforts to promote women's equal rights need to be made. (260 words)05、写作题目：“追星”现象It was reported recently that one woman followed actor Andy Lau around for ten years. What is your opinion about those fans who idolise certain celebrities?写作范文：Idollsing Celebrities Goes Too FarCelebrity worship has been identified as one of the most common forms of idolatry these days, However, many fans go too far with pursuing stars. Some have facial plastic surgery just to look a little more like the star they worship. Others even pay all their money to see the stars in person. I personally hold that blindly worshipping famous people should be deterred from becoming rampant.Due to daily gossip columns in the tabloids and the ubiquitous celebrity news in the media, researchers report that about one third of people suffer from Celebrity Worship Syndrome, an actual syndrome that can become obsessional, replacing conventional relations, Some fans of famous people tend to indulge ins daydreaming about stars they worship. Having less communication with their friends and families, some obsessed fans ignore conventional relations, leading to psychological problems or disorders. Blind worship undermines young people's spiritual pursuits in real art, literature, philosophy, and science, without which they can hardly hold the sacred torch of civilization transferred to them from preceding generations. It is no exaggeration to say that blind star-worship will probably lead young people whose discretion is not enough into abysmal darkness, and thus buried with them is the hope of the future.In conclusion, given the above harmful effects of blind star-worship, every effort must be made to help fans to get out of the hopeless swamp of star-worship. (231 words)06、写作题目：经济发展与环境保护Some people think that economic development should take priority over environmental protection as this strengthens the economy, provides jobs and increases people's standar ds of living while others think this is only short-term thinking and that mankind has a long-term responsibility to protect the environment. What is your opinion about this?写作范文：Both Economic Development and EnvironmentalProtection Are Indispensable, I am not supportive of the idea that either takes priority. It is necessary and absolutely possible that economic development and environmental protection co-exist, in the sense that both of them are indispensable factors for the prosperity of society.Economic development is seemingly more important, due to the fact that it creates enormous job opportunities, improves living conditions and increases government revenues. Yet, the above goals can only really be reached on condition that the environment is well. protected. And, interestingly, it is the economic development per se that provides the money and personnel resources required for the protection of the environment. A well-preserved environment is the groundwork for the economy and in a way promotes economic growth. A fast-developing and well-functioning economy calls for a good environment, which offers essential resources, e.g. wood, coal, water, etc.for production. Once the environment deteriorates, the production process is likely to be disturbed or even halted. What is worse, natural disasters that come with the worsening environmental conditions might even paralyses the whole economy mid pose a severe threat to human life, The pursuit of short-term economic profit is the destruction of our home and that of our posterity.So, economic development and environmental protection are equally important. In this sense, we are actually working on an environment-friendly economy. Given the status quod, it is possible to realize the co-existence of the two as long as we are conscious and determined enough. (240 words)07、写作题目：献血Many university students donate blood because they either get marks or benefit in some other way while others see it as helping others in need. Do you think that students should get something in return for donating blood?写作范文：Universities Should Reward Blood DonorsShould university students be rewarded for donating blood or should they do it out of altruistic reasons? As far as I am concerned, I believe that students should not make the donation merely in order to obtain rewards. Yet, institutions ought to devise so me incentives to promote blood donation.To begin with, the act in question is to help or even save the lives of people in need. In view of the notion that prize and punishment should be meted out accordingly, donors should be rewarded for their selflessness. Second, the implementation of various incentives also serves to encourage students to donate blood. As the saying goes, "One good turn deserves another." Even if donors do demand some repayment, it is utterly justified. Meanwhile, the establishment of the incentive policy also reinforces an advantageous societal system where good deeds are encouraged. Nevertheless, the foregoing points do not justify able-bodied students eschewing blood donation if no rewards are offered. Otherwise, our world would be replete with mercenary individuals; and no society can survive let alone thrive when it is corrupted with selfishness.In the final analysis, students should make donations in an altruistic fashion"．However, universities ought to present some rewards to express their gratitude. (205 words)08、写作题目：计算机翻译With the amazing development of computer technology, computers can translate all kinds of languages well so our children don't need to learn foreign languages in the future. To what extent do you agree with this view?写作范文Machine Translation Cannot Replace Human TranslationMachine translation has been the focus of intense interest since the advent of programmable computers. In spite of its increasing popularity, I personally hold that it cannot replace human translation. Learning foreign languages will still be important in the future.First of all, as globalization and communications are bringing the world ever closer together, ever more urgent he need for global citizens to be competent ins other languages. In a world where nations and peoples are ever more dependent upon one another to supply goods and services, solve political disputes and ensure international security, understanding other cultures is paramount. Learning another language gives the learner the ability to step inside the mind and context of that other culture.Without the ability to communicate and understand a culture on its own terms, true access to that culture is barred. Furthermore, having a second language on a resume is almost a requirement of the job-seeking professional. Businesses recognize that a person with the ability to speak a second language fluently is a valuable asset, It also shows off the capacity of the aspiring job candidate to learn and assimilate complex systems of information, a talent that is sure to catch the attention of any human resources department: Though computers can translate different kinds of languages, machine translation has many shortcomings, making it impossible for it to replace human translation. Computer translation is understandable, but not of publishable quality. Furthermore, the computer cannot discern context and intended meaning the same way a human can. On the contrary, human translation is more accurate and reliable.In conclusion, computer translation cannot replace human translation andlearning foreign languages will remain vital in the future. (281 words)09、写作题目：空气污染Many cities in the world are facing increased air pollution. Suggest ONE way to deal with the problem of air pollution in cities.写作范文：Use Clean Energy OnlyThe world is facing an uphill battle to reduce air pollution which has led to a series of health hazards. In my opinion, the real solution to air pollution is to replace fossil fuels with clean energy like solar and wind energy.Firstly, by utilizing the sun and the wind to produce clean energy, pollution from dirty energy such as fossil fuels can be greatly reduced. The overuse of fossil fuels such as coal has given rise to the emission of pollutants like nitrogen oxides and carbon dioxidewhich are looming as one major threat to air quality. According to the official statistics, carbon dioxide emission reached 18.57 million tons in 1999, posing a serious threat to air quality, Therefore, harnessing solar and wind energy can effectively reduce pollutants emission from fossil fuels and significantly improve air quality. Secondly, renewable forms of energy such as solar and wind energy are non-polluting and environmentally friendly, It is widely acknowledged that solar and wind energy are clean, free and inexhaustible. They provide energy for cooking, lighting, heating and cooling without any direct emissions.In conclusion, to win the battle against air pollution, some urgent measures have to be carried out immediately. Replacing fossil fuels with sustainable clean energy is the t op priority. (211 words)10、写作题目：噪声污染Urban noise pollution from cars, aircraft, building sites and neighbors is on the increase and affecting all levels of society. Suggest ONE way to reduce noise pollution.写作范文：New Technology Is One Way to Solve Noise PollutionThere have been an increasing number of complaints and lawsuits about noise pollution in some major world cities. The problem with noise is not only that it is unwanted, but also that it negatively affects human health and well-being. In my opinion, the government should attach importance to the research and application of technology in order to reduce noise pollution.First, the application of sound-absorbing or sound-insulation material shows the quickest sign of the reduction of noise pollution. Noise inside a building can be reduced if both the external and internal walls are made of sound deadening materials. Heavy and dense materials such as masonry or brick walls are better for sound reduction. The application of sound reduction materials is economically and technically feasible in dealing with four main noise sources, namely transportation, industrial production, construction, and social activities. Furthermore, the introduction of hybrid cars has made advances in the reduction of motor vehicle noise. Noise from transportation is one major source of noise pollution. The application of cars with low level noise will be effective in reducing noise emission.In conclusion, with people exposed to dangerous sound levels on the rise, noise pollution has become a common occupational and environmental hazard. I strongly recommend that the government should spare no efforts in funding and investing in new technologies which will be essential in noise pollution reduction. (227 words)。
