fresh water People have different views with regard to how to use fresh water. Some people argue that they can use fresh water as they like, but I believe that there are more benefits when governments control the use of fresh water. (While there are some benefits on using fresh water as people like, I would argue that it is better to control the use of it by governments.) On the one hand, people can benefit from drinking fresh water freely. To be more specific, people do not pay for water bills if they are allowed to use fresh water as they like, and this practice can help them reduce financial burden. For example, the high price of water has become a huge burden for some impoverished families in some countries. If people do not need to pay for it, they can spend this money on other items, which can help them to improve the quality of life. On the other hand, I would argue that it is better to restrict the use of fresh water by governments. First of all, this practice is beneficial for people to save water. Most countries around the world are confront with(面对) the problem of water shortage in recent years, if governments do not restrict the use of water, people will waste a large number of fresh water every year. In the future, people will face the situation without any water. Secondly, if people drink fresh water as they like, they are more likely to get stomach illness because there are many bacteria in the water, which people cannot see them directly. Therefore, governments should control the use of fresh water to ensure that everyone can drink safe and clean water. In conclusion, while there are some advantages on using fresh water as people like, I would argue that it is better to control the use of it by governments.

the effcts on buying foods With the development of global economy, it is true that people can purchase numerous kinds of food both from home and abroad (国内外)in recent years. In my opinion, the positive effects of this trend outweigh the negative effects. （In recent years, it has become far more normal for people to purchase foods from abroad.） On the one hand, this practice might bring air pollution and a waste of energy, which will pose a threat to our environment. As we all know, foreign foods are mostly transported by ships and planes, which need to consume a lot of fossil fuels. As a kind of non-renewable sources, the more exotic foods people consume, the less energy there will be. Besides, during the process of transportation, the gas emissions from ships and exhaust fumes from planes will lead to global warming, which may have a devastating effect on our planet in the future. However, I would argue that these drawbacks are outweighed by the benefits. Firstly, if residents have easy access to more kinds of foods form other countries, it will decrease individuals' costs of living. This means that with the increasing number of exotic foods, local foods might face a fierce competition. Therefore, to compete with them, most food retailers will decline the prices of foods. Consequently, inhabitants can spend less money on foods, and they can use this money in other aspects, which can help them improve the quality of life. Secondly, this practice can also boost the economy of other countries and provide more job opportunities in food industry, since the increase of the sales volume of foods. In conclusion, while there are some detrimental effects if people buy food from overseas, I would argue that this trend brings more benefits than drawbacks.

the effects on living big cities With the development of large cities, we cannot ignore the problem that the expansion of the cities brings lots of pollution in our daily lives. Therefore some people argue that if people live in metropolises (大都市), it will has a great impact on people's fitness ，which I could not agree more. On the one hand, people can benefit from better health care in big cities. Firstly, compared with rural countryside，there are well-established healthcare systems in metropolises. This means that people have more chance to acquire superior medical services and pay lower costs. For example, in GuangZhou, patients who enjoy the better care from famous hospitals only need to pay the 20 percent of the whole medical costs and the local government will use the healthcare budget to fund the rest of them. However, it is hard to afford this money for people in some small towns' states. Secondly, there are many more well-known hospitals in metropolises, and patients more like to get better treatments there. To be more specific, these hospitals usually have advanced medical equipment, accomplished doctors and professional experts. Patients with server sickness have more possibilities to recover. That is the reason why there are thousands of patients from different districts to go and see doctors in the Beijing XieHe hospital which is the most famous hospital in my country every year. On the other hand, I would agree with those who argue that people live in large cities more likely to suffer ill-health problems because of contamination and pressure. It's not uncommon to hear about the news about the increasingly severe problem of air pollution in large cities. This trend makes urban residents suffer respiratory diseases easily, and affecting the level of health in the general population. Regarding to another problem, pressure, it has been an serious impact on people's mental and physic health in recent years. Because most workers who living in metropolises have to face fierce competition in working, and they lack enough time to have a rest or to do regular exercises everyday. Therefore they might to feel stressed out and more likely to get some occupational diseases and mental sickness, such as anxiety and depression. In conclusion, I believe that there are many detrimental effects on people's health when they live in big cities, and people should pay more attention on this issue.

task 1 Some people think that practical subjects are more important than theoretical subjects in university, and the latter will be replaced by the former in the future. To what extent do you agree or disagree with this idea? (250 words, opinion) In this competitive society, employment experience has become very important features of ordinary students lives. While some people believe that it is not necessary to provide theoretical knowledge at college, but to give practical training, I disagree with this point of view. On the one hand, I agree that practical courses are necessary in order for students to learn. First of all, students could use what they have learned form practical subjects in realistic, and help them cope with practical problems. For example, students can acquire computer skills in university, which can be applied in their studies as well as their working lives. Secondly, students could enhance their vocational skills and potential attraction for employers according to practical subjects. They could acquire more job opportunities compared with applicants who lack related working experience, because some positions just seek for experienced applicants. Nevertheless, I believe that theoretical knowledge is the foundation of practical skills. That is to say, the current knowledge of students is not substantial enough to face the requirement of practical training. If students are not taught professional knowledge in university, they just depend on some basic academic knowledge that they studied in the high school. In fact, they are difficult to progress or gain abundant employment experience in practical courses. Moreover, students can summary formers’ experience and avoid making same mistakes according to learning theoretical knowledge. In conclusion, for the reasons mentioned above, it seems to me that theoretical subjects are as much as important as practical courses, without the support of theoretical knowledge, it’s hard for students to do well in practical courses.
