One possible version:
Recently we’ve had a discussion about whether students of Senior 3 should take physical exercise.
As we know, every coin has two sides. 55% of the students think they should take all kinds of exercise every day, such as doing morning exercises, playing table tennis and playing basketball. Proper exercise can build up their body and prevent lots of diseases. What’s more, sports let their brains have a good rest so that their study will be more effective.
On the other hand, 45% of the students believe taking exercise is a waste of time and it is tiring. After having sports, they are too excited for a long time to pay attention to their lessons. And it’s possible to be hurt in sports.
In my opinion, we should take proper exercise in order to study more effectively, but never spend too much time on it, because our study time is very limited and precious.
