Boys and girls, let's begin our class meeting. As you know, some students in our class get online very

often, even on wekkdays. So today we will talk about computer and Internet.

     I think the important machine is computer. Computers and Internet change the world a lot. They have

advantage and disadvantage. One the one hand, if we learn to use the modern machine and surf the Internet,

we can learn more and more knowlege and information faster and better. They can help to open up our eyes

to the outside world. On the other hand, if we spend much time playing computer games, making friends on

the line and writing to each other, we will be worse and worse in our study.

     So I want you, my dear students, to be careful with computers and Internet. You'd better not get online

on weekdays. On weekends and holidays, you can surf the Internet with your parents. Then computers and

Internet will help with your study, not do harm to you.
