Good morning, class!

     We know that there are too many net bars around us. The Internet is popular and it makes our lives

colorful. Many of us like going online very much because we can learn how to use the computer and get

more information from the Internet. We can learn English. We can read some good newspapers and

magazines. It can make us clever in playing computer games. We can send E-mails to our friends quickly. We can chat(聊天) freely online with our friends. It can help us get in touch with people from all over the world.

     But some students spend too much time in playing computer game and some stay in the net bars all day and all night. Teenagers even get to have boyfriends or girlfriends online. They write too many letters to

each other. It takes them to much time to chat online so they do worse and 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. We should get online with adults(成人)--our teacher or parents.

     At the same time, if we have lots of free time, we can do some out-of-class activities at school. We

usually have activities from 4:50 to 5:50 in the afternoon. We have different kinds of activities. If you are

interested in sports,you can play basketball or football.We can go to the English Corner.We can practice

talking in English there. We 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.

     Thank you for listening to me. That’s all.
