As it is known to us, fewer and fewer students do sports regularly, what makes them weak and easily tired.
There are many reasons about this. First of all, some of the students complained that they have too many homework, resulting in less time to take exercise. Beside, some of them think that it is very difficulty for them to keep doing exercise, because it is a very hard thing.
Because lack of physical activities, many students are in poor health. I suggest that our school must take measures to encourage more students to take part in sports. For us students, no matter what busy we are, it is necessary to spare some time to do exercise.
