We asked thirty young people between 14 and 18 several questions. All the children had computers
at home. The average time spent on a computer in a week was about 12 hours, with the highest about 32
hours, and the lowest 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 common 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.
