16. Dear Mr. Headmaster, I am writing this letter to tell you something about our canteen. There are many kinds of food in our canteen, and generally they are cheap. Some food is delicious. The dining environment has been improved, with the walls painted and some pictures posted up. The students are satisfied with the new look. But students are not given a proper helping of every dish. Also, as the number of the students continues to increase, there is not enough space for us to have meals there. As a result, many of us go out to have meals. All in all, there is still much room for improvement in food quality and service. Best regards, Sincerely yours, Li Ming 17. Students Like Optional Courses This term our school had offered more than 10 optional courses, from which students can choose. The courses are given from 3:30 to 5:00 every Tuesday afternoon. Students take great interest in the optional courses. Their favourites are computer, spoken English, arts and so on. They say they have got a great deal of practice and they have learned a lot that is not taught in textbooks. However, students hope more optional courses will be offered while their homework should be reduced. They suggest more trips and visits should be organized so that they can learn more about what is going on outside school. 18. About the discussion we’ve had about whether China should devote major efforts to developing car industry, opinions are divided on the question. 60% of the students think China should fully develop car industry. They believe this will speed up the development of the national economy. More workers will be employed. With cars the people’s life quality will be raised. They will save time and be more convenient in their life and work. On the other hand, 40% of them think China should control its car industry development. Otherwise, the city traffic will be even heavier and more traffic accidents will take place. At the same time, more land will be used for the new roads. What is more, air and noise pollution will become more serious. 19. Attention, please! I’m going to give you a summary of today’s discussion about whether we would go online in our spare time. Most students think they (we) can go online as much as possible in our spare time because we are free then. Through the Internet, they can gain plenty of the newest knowledge and the latest news at home and abroad. What’s more, network offers them(us) a convenient way to communicate with each other. The Internet makes their lives outside class colourful and various. On the other hand, a few students partly agree to this idea. Going online is part of our daily life. They suggest a time limit. They’ve found that more students are playing computer games instead of studying their lessons. There’re few students who are often absent from school for days. 20. Dear Tom, I felt terribly sorry to learn that both your parents had been killed in the September 11th Incident. In this incident the World Trade Centre, which used to be one of the tallest buildings in the world, was completely destroyed and thousands of people lost their lives. I’m very angry about the terrorist activities. We are against all forms of terrorist activities and support the war against the terrorism. Don’t be too sad. Don’t lose heart. After all, the majority of the people in the world love peace. I hope you can recover from the sadness as soon as possible. Be sure to take good care of yourself. Best wishes. Yours, Xiao Fang 21. Ladies and gentlemen, Yesterday our teacher of English asked me to say something about pollution. Now, I give you my views on this vital question. As a matter of fact, the effects of industrial pollution are well known to everyone --- polluted air, polluted water and polluted earth. Though a great deal is already being done to control these effects, the problem of pollution is still serious. Continued population increase, smog and chemical waste produced by factories and cars, not only threatens to exhaust our resources, but also pollutes our environment. We do need clean air, safe water and our children’s health. In my opinion, to solve the problem of pollution, everyone must refrain from polluting our environment. We should know that this is the duty of every individual, not that the government alone. 22. Last week, we did research into how laid-off workers get their new jobs. We had a discussion in three groups and then began our research separately. Group One surfed on the Internet and learned that most of the laid-off workers had already got their new jobs. In the vocational training center, the students in Group Two were told that there were five training courses for laid-off workers. After training, they began working as repairers, cooks, typists, household workers and salespersons. The other students interviewed some laid-off workers who had got new jobs. A woman said, “With the help of the city government, I’ve found my job. …” What a great deal we’ve learned through the research. 23. The Way to Keep Healthy It’s very important for us to keep healthy in our everyday life. But how? Here is some advice for you to follow. First you should have a healthy diet. It’s a necessary to eat enough fresh fruit and vegetables, because they contain all kinds of vitamin that you need every day. But do not eat too much fat, such as cheese, butter or anything too fatty. Too many sweets can do harm to your teeth. So you had better not eat too many sweets or chocolates and keep off coffee. Good habits can help you keep fit. Doing regular exercise is certainly a good way to ensure your body is healthy. After a day’s work, an eight-hour sleep is needed. And avoid working too hard. Remember smoking can damage your health, so never smoke. 24. In today’s society, competition and cooperation are equally important. People are cooperators in their life. They share information, natural resources, human resources and many other things. Cooperation is the way to a happy life. At the same time they are competitors. In competition, they learn from their opponents, gain courage and confidence. Without competition, science and technology would not have been developed so rapidly. And without cooperation, the world would be quite different. Cooperation and competition are like two sides of a person. They can’t be separated.

亲爱的校长先生，我写这封信告诉您我们的食堂的东西。有许多种食品在我们的食堂，而且他们一般都便宜。有些食物是美味。餐厅的环境得到改善与墙壁和一些照片，张贴。学生们满意新面貌。但学生没有得到适当的帮助的每一道菜。此外，由于学生人数不断增加，没有足够的空间，我们有吃饭的。因此，我们许多人出外用膳。总的来说，仍然有食品质量和服务改善的地方。的亲切问候，此致，李明17。像选修课程，学生在我们学校有长期提供超过10个选修课程，学生可以从中选择。该课程是从3:30到5:00每周二下午。学生参加选修课的极大兴趣。他们所喜爱的是计算机，英语口语，艺术等。他们说，他们已经得到了大量的实践，他们学到了不是很多教科书教。然而，希望有更多的学生选修课程将提供他们做功课的同时应该减少。他们建议更多的考察和访问应当组织，令他们可以了解什么是去校外的。 18。关于我们有中国是否应该大力发展汽车业，意见分歧的问题进行讨论。 60％的学生认为，中国应充分发展汽车产业。他们相信，这将加快国民经济的发展。更多的工人将被采用。同车的人们的生活质量将会提高。他们将节省时间和更方便他们的生活和工作。另一方面，其中40％的人认为中国应该控制它的汽车业的发展。否则，城市交通将会更重，更交通事故的发生。同时，将更多的土地用于新的道路。更有什者，空气和噪音污染将更加严重。 19。注意，请！我打算给你今天的我们是否会继续在我们的业余时间在线讨论的摘要。大多数学生认为他们（我们）可以在我们的业余时间在线尽可能因为我们是自由，然后。通过互联网，他们就可以获取大量的最新知识和国内外的最新消息。更重要的是，网络为他们提供了（我们的）一种方便的方法互相沟通。因特网使课外和各种色彩缤纷的生活。另一方面，少数学生部分同意这个想法。上网是我们日常生活的一部分。他们建议的时限。他们发现，越来越多的学生玩，而不是研究他们的经验教训电脑游戏。还有谁是你经常从天缺课，几个学生。 20。亲爱的汤姆，我感到很遗憾地得知，你的父母已经在9月11日死亡。在这一事件中，世界贸易中心，曾是世界上最高的建筑之一，被完全摧毁，数千人丧生。我非常愤怒，对恐怖活动。我们是反对一切形式的恐怖主义活动，支持打击恐怖主义的战争。不要太伤心了。不要气馁。毕竟，世界上热爱和平的人民的大多数。我希望你能恢复过来，尽快悲伤。一定要保重好自己的照顾。最良好的祝愿。你，小方21。女士们，先生们，昨天我们的英语老师要我谈谈污染。现在，我给你在这一重要问题的意见。作为事实上，工业污染的影响是众所周知的---污染的空气，污染水和污染土。虽然大量工作正在进行，以控制这些影响，污染问题依然严重。人口的不断增加，烟雾和化学废料的工厂和汽车生产的，不仅威胁用尽我们的资源，而且污染环境。我们需要清洁的空气，安全饮水和我们孩子的健康。我认为，要解决污染问题，每个人都必须避免污染环境。要知道，这是每一个人的责任，而不是单靠政府。 22。上周，我们也将研究如何下岗下岗职工得到他们的新工作。我们有三组讨论，然后开始我们的研究分开。第一组在互联网上冲浪，得悉大部分下岗职工已掌握新的工作。在职业培训中心，在第二组的学生们被告知有五个培训课程，下岗职工。经过培训，他们开始为修理，厨师，打字员，家庭工人和销售人员的工作。其他学生采访了一些下岗职工，谁获得了新的就业机会。一名妇女说，随着城市的政府的帮助“，我发现我的工作。 ...“什么很大，我们已经通过研究的经验教训。 23。的方式保持健康是非常重要的，我们保留在我们的日常生活健康。但如何？以下是一些您的建议遵循。首先你应该有一个健康的饮食习惯。这是一个必须吃足够的新鲜水果和蔬菜，因为它们含有各种维生素，你需要每天。但是不要吃太多的脂肪，如奶酪，黄油，或者有太大的脂肪。太多的甜食可伤害牙齿。所以你最好不要吃太多甜食或巧克力和挡咖啡。良好的生活习惯可以帮助您保持健康。定期做运动无疑是一个很好的方式，以确保你的身体是健康的。经过一天的工作，8小时的睡眠是必要的。并避免工作太辛苦。记住吸烟会损害你的健康，因此不要吸烟。 24。在今天的社会，竞争与合作同样重要。人们在他们的生活合作者。他们共享信息，自然资源，人力资源和许多其他的事情。合作是一个幸福的生活方式。与此同时，他们是竞争对手。在竞争中，他们学习他们的对手，获得勇气和信心。没有竞争，科学技术就不会发展得这么快。没有合作，世界也将完全不同。合作与竞争就像一个人的两个方面。它们不能分开。
