Good morning, boys and girls. Today I’ll give you a talk about going online.
We know that there are too many Net bars(网吧) around us. The Internet makes our lives interesting. Many of us like going online very much because we can learn how to use the computer. We can learn English and read some newspapers and magazines to know more information around us. It can make us clever in playing computer games. Also when we send e-mails to our friends, they can get them right away. 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 study well any more. I think we mustn’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 school. We usually have activities from 4:50 to 5:50 in the afternoon. We 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 afternoon. I hope we can spend more time on our subjects or on such activities that we can learn a lot from and less time on the Internet.
That’s all! Thank you.
