Question

SOS!帮忙改下这篇composition!
I did a survey of how long we play sports on weekends.Here are the results.
There are 40 students in my class,about 5 students play sports 3-4 hours a day,23 students play sports 1-2 hours a day.There are 10 students play sports half an hour a day and 2 students don't play sports.
On weekends,I often play badminton or run.I spend 1-2 hours in doing exercise every weekend.I think all the students should do more exercise on weekends.Because we studied all day from Monday to Friday and it makes us feel tired.Doing exercise can makes us feel happy,we can be more outgoing.It's good for our health.It makes us get away from illness.The more exercise we do,the healthier you will become.
首先改一下语法错误,然后还有句子通顺程度,
