Dear Mr Smith,
Among them,21 students like doing sports because they think it is good for their health. 32 students enjoy listening to music. They think music can help to relax their brain. 25 of them like to play computer games when they are free because they think most of the games are interesting . 18 students like reading books. They believe they can learn a lot from books. I think playing too many computer games may be bad for our eyes as well as our study. So i like listening to music better when i have time.
Yours,
Sally
