If I ask you “What is the most important thing in your life?”, maybe you will say “Computers and the Internet”.      The first computer was made in 1946. It was very big but 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.”      The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, send e-mails, do some shopping, play games or make friends.                   Young men, especially the middle school students like the Internet very much. They often go into the Internet bars as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their names, ages and sex(性别). They are so interested in making the “unreal friends” that they can’t put their heart into study. Some of them play the games in the Internet bars all day and all night. Many of them can’t catch up with others in many subjects because of that.       Now the government has done many things. Some gangster Internet bars(黑网吧)have been banned(取缔). But that’s not enough. The teachers and parents are still worrying about their students and children.     We can use computers and the Internet to learn more about the world.
