     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.
