Dear classmates:
Im Li Hua After the discussion we found that 70% of the students think they should take all kinds of exercise every day but not spend too much time. They think exercise builds body and can keep them healthy. Sports also let them have a good rest so that their study will be more effective.
On the other hand 30% students believe taking exercise is tiring and its a waste of time. They say that after having sports they are too excited for a long time to focus on their lessons. And its possible to be hurt while doing sports.
A game is a kind of recreation after a hard study. We play games in the playground at half past four in the afternoon every day. When we play games we have a very good time.
The boys play more games than the girls. Most of the boys like to play football or basketball. The smaller boys like table-tennis.
Most of the girls like the swing and badminton. They also play other games but they seldom play football.
Games can build up our health. The famous proverb says. “All work and no play makes Jack a dull boy.”
So I think all of us should learn to play one or two games.
