My friend Peter was kind and lovely. But as a student, he was bad at math, English and science because he didn't have an aptitude(资质)for that kind of study.
One day we were playing football and the ball got stuck in a tree. Peter climbed the tree to get it, and one of the teachers, John Marston was looking out of the window, noticed that he was a talented climber. Mr Marston was an expert (专家)in climbing. He had climbed many mountains.
One weekend Mr Marston invited Peter to climb Mount Kilimanjaro. Peter really enjoyed the climbing. Mr Marston told Peter he was a very talented climber for his age. Peter left school three years later with no qualifications (毕业证)，but he kept climbing regularly until he became very good at it. In his early twenties, he became a professional climber. He said, “I’ll always remember Mr Marston because he showed me I had an ability which no one else, including me, knew about."

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?
