As a father, I always do my best to help my son, Peter. I like to help him with his study. I encourage
him to join team sports. I send him to the summer camp if he wants to go. I also teach him to be both a
good student and a useful man.
     He used to make me feel proud. I often thought he was the best son and I was the best father in the
world.
     However, things changed two years ago. It was Peter's 12th birthday. My wife and I bought him a
computer as a present. We thought it was necessary for him to learn how to use a computer in the modern
world. We knew that some children were addicted (上瘾的) to computer games and that they didn't study
or work at all. Someone said that computers and the Internet were bad for children, but I didn't worry
about it. I trusted (信任) my son. I believed that he could control himself. Peter did very well at first. He
played computer games, but for only two hours every week. Most of the time he studied or wrote articles
on the computer. We felt very happy to see that.   
     When we finally learned that Peter was also addicted to computer games, it was too late. He didn't like
studying at all. He no longer joined team sports. Sometimes we even couldn't find him at night. He spent
several days and nights at the Internet cafe. We tried everything to help him, but nothing worked. What
should we do?
