  1  All the teenagers we chose said they had computers at home. We asked them how much time they spent on their computers in an average week, but we were most interested in what they used their computers for. The average time spent on a computer in a week was about 12 hours, with the highest user averaging 32 hours and the lowest user only 5 hours.   2    3  Fourteen teenagers told us they did some word processing at home, but not very much. Only 2 of them said that computers helped them with their studies, while 8 of them told us they kept addresses and telephone numbers on their computers or used them as diaries. Only 3 of them said they were learning to program computers, and nobody looked up information (other than their address lists).   4 

The results indicate quite clearly that computers are seen by most young people as little more than game machines.   5  It seems to us that, although computers are common in the homes of teenagers, they have not yet become useful tools in everyday life.

A．There no big difference between boys and girls.

B．All of the teenagers questioned said they regularly used to play games.

C．We questioned thirty young people between 14 and 18.

D．But some adults admitted that they had no computers at home.

E. None of them used their computers for any other purpose.

F. I don’t know how important a computer is for teenagers.

G. The other important users are for word processing and organizing address lists.
