As a middle school student of Senior Three．I do sports one and two hours a day, such as doing morning exercises, playing basketball, long-distance running and so on．I think it is very helpfully in me．Take exercise makes me even more healthier so that I won't be ill very often. What's more, I also get myself relaxing in different kinds of sports. Only in this way I do a better job in my study in high spirits．For doing physical exercise, I'm becoming stronger and more confident than ago．I did think it is necessary for everyone to spend some time on sports every day so people's health is important in modern life．
