  Dear friends I have some advices about computers to share with you. Now the computer had become a good friend of us students. It has made our life more co?lourful. We can get information fast under its help. Through the Internet we can talk with people thousands of miles far away.

  However there have some disadvantages. It gives us some trouble. I'm afraid that we spend a bit too much time play games in front of the screen. Our studies and health are getting worse. Our parents are beginning to worry us. In addition we surely have less time leaving to get together with others. In this case the com?puter is taking away our human nature.

  My suggestion is that we would use the computer to improve our life and work on the one hand and enjoy the sunshine or fresh air with our friends on the other.
