We asked thirty young people between 14 and 18 several questions. All the children had computers at home. The usual time spent on a computer in a week was about 12 hours, with the highest user about 32 hours, and the lowest user only 5 hours. Most children said they usually used computers to play games. Fourteen children told us they did some word processing(文字处理) at times. Eight people told us they kept addresses and phone numbers on their computers or used them as diaries. Only three people said they were learning to write computer programs and nobody used databases(数据库). Only two of them said computers helped with their lessons. The diagram(表格) gives all the results one by one.

The results show that computer use is quite high among 14-18-year-old children. They also show quite clearly that computers are seen by most young people as little more than game machines. It means to us that, though computers are common(普遍) in the homes of young people, they have not yet become popular in everyday life.
