15、题缩小到某一个范围，对于大学生而言，对于网络上的娱乐活动可能更有话可说，所以可以把这个很泛的话题限制在网络娱乐活动。而对于网上活动的利弊想必同学们都可以说出一二，好处比如能够开阔眼界、增长知识，弊端就是很容易上瘾，影响学习生活；而个人的看法就是用其精华弃其糟粕，即利用其好处，对不好的地方避而远之。 Sample1:Recreational Activities 21st century has brought with it an unprecedented variety of recreational activities ranging from traditional outdoor

16、activities such as playing ball games to all kinds of online ones, the latter of which is a great appeal to the young generation. So Id like to narrow my topic down to online recreational activities. It goes without saying that various activities brought by modern technology have greatly broadened o

17、ur horizon and brought much excitement to us. With access to the Internet, you can get to know people from any country in the world and you can talk with them, play games with them - a temptation very hard to resist, and even see them via web cam. The disadvantage, however, is that anyone who lacks

18、self-control would very easily get lost and become addicted to the online world, which in turn might seriously affect their life, work and interpersonal relationships. As a college student, I think what really matters is to make better choice and exert more discipline. Wed better take advantage of g

19、ood online recreational activities to enrich our lives and broaden the scope of knowledge. When it comes to those addictive, time-consuming and less meaningful activities, I think to stay away from them is a wise decision. Sample2:Recreational Activities In the era of information and technology, the

20、re are all kinds of recreational activities. Some people think those recreational activities are great and necessary, because they can help people relax from the hard work and study. Some of the activities, such as hiking, jogging, can help people relax physically; while some of them, such as surfin

21、g the Internet, can help people relax mentally.However, some people think that so many kinds of recreational activities may have a bad effect on our lives. Some people may not resist some temptations from those activities, and indulge themselves in those activities. At last they are lured away from

22、their study or their work.In my opinion, we should pay more attention to the advantages of various recreational activities and make the most of them. Meanwhile, we should learn how to use those activities positively, and make them a helpful tool for our development.Sample3:Recreational Activities Wi

23、th the development of living standard, people spend more time on various forms of recreational activities. People can do sports, sing karaoke, go dancing, go to the movies, play video games or online games, or surf the Internet. Recreational activities are good to peoples health, both physically and

24、 mentally. Sports and dancing can keep people fit. Singing karaoke, playing video games or online games can satisfy peoples imagination. Surfing the Internet can bring people a lot of information and knowledge. However, recreational activities might be harmful if people are addicted. Spending too mu

25、ch time on recreational activities will seriously influence peoples normal lives, especially work and study. Therefore, people will benefit from recreational activities only if they take part in them properly. In-class practice:In-class practice: 上网（surf the Internet)已成为越来越多人生活的一部分，请谈谈上网的利弊 Surf the

26、 InternetSurf the Internet With the development of science and technology, internet plays a more and more important role in our life. There are a lot of advantages using internet, among which the following are the most obvious in my mind. First, The convenience internet bringing to us is self-eviden

27、t. We can easily get access to various kinds of information and know whats going on around the world staying at home. Second, internet makes our life more colorful and wonderful. We can watch movie, TV, and play games as we like. It helps us to relax whenever we need to. Third, internet is time-savi

28、ng and energy- saving. We dont have to spend so much time in the library or market as we used to do; neither do we have to search from piles of books to find out a piece of information we needwe hand it to internet. But every coin has two sides: there is no exception for internet. More and more peop

29、le take advantage of internet to cheat others, and cybercrime is increasing rapidly. Besides, many people are addicted to internet, resulting in great harm. Yet we cant go without internet. Then we should make good use of it and try to avoid its side effects.Owning a Private Car 1. 目前，有越来越多的人拥有私家车；2
