科目：初中英語 來源：牛津譯林版8A英語期中專題練習(xí)-任務(wù)型閱讀 題型：填空

Good morning, boys and girls. Today I’ll talk about going online.

We know that there are too many Net bars (網(wǎng)吧) around us. The Internet can make our lives interesting. Many of us like going online very much because we can learn how to use computers. We can learn English and read some newspapers and magazines to know more around us. It may make us clever in playing computer games. Also when we send e-mails to our friends, they can get them at once. It can help us keep in touch with people from all over the world.

But some students spend too much time in playing computer games and some stay in the Net bars all day and all night. It takes them too much time to chat online so they do worse in their lessons and they don’t want to study any more. I think we shouldn’t get online when it is time for us to study. We can do it in summer or winter holidays. I think we should get online with our teachers or parents.

At the same time, if we have lots of free time, we can do some activities after class. We usually have activities from 4:50 to 5:50 in the afternoon. You can play basketball or football. We also have some interest groups in school, such as drawing, singing and dancing. We can go to the English corner on Monday afternoons. We hope we can spend more time on our subjects or on such activities that we can learn a lot and spend less time on the Internet.

That’s all! Thank you.
