    　　Today almost everyone knows computers and Internet(因特网). If I ask you “What is the most important in your life?” Maybe you will say “Computers and Internet”.

    　　The first computer was made in 1946. It was very big and it worked slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said, “People can't live without computers today.”

    　　Many students like Internet very much. They often go to Internet bars(吧) as soon as they are free. There they make friends and maybe they have never seen these friends.

Many of them can't catch up with the others on many subjects because of that. We can use computers and Internet to study or to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and Internet.
