As is apparently shown in the chart above, many middle school students have problems both physically and mentally, with 70% of students having learning anxieties as well as bad eyesight, and a larger percentage lacking sleep. Coming next is the lack of physical exercise. 40% of the students surveyed won't obey their parents or teachers. Still fewer claimed not to have enough communication with others.
So far as 1 am concerned, we students should balance our physical exercise and studies. Just like a saying goes:" All work but no play makes Jack a dull boy," without a sound body one cannot achieve anything; however, too much attention has been paid only to studies. Therefore, I suggest we be given less homework and more time for out-of--classroom activities to solve all the problems. Only in this way can we lead a healthy life.
