As you all know, the study work is heavy in high school. There are often more than 10 courses a day including the evening. That will take more than 9 hours in study a day, and without weekends. The students in high school are exhausted after school and not willing to do the physical exercises anymore. In fact, it is not only very bad for health but also bad for study. The teenagers have to do enough exercises to keep healthy and growing tall. And doing physical exercises can make a people strong and lighten one up, refill the energy to study more efficiently. So, the high school students should do physical exercises. They can do some sports, such as playing football or basketball, running, swimming and so on.

眾所周知，在高中的學(xué)習(xí)任務(wù)是很繁重的。包括晚上，每天經(jīng)常有超過10節(jié)課。這將會(huì)占用9個(gè)小時(shí)用來學(xué)習(xí)，還沒有周末。放學(xué)后高中生都已經(jīng)筋疲力盡了，不再想去鍛煉身體。實(shí)際上，這不但有害健康，還不利于學(xué)習(xí)。青少年必須要做足夠的身體鍛煉才能保持健康，繼續(xù)長(zhǎng)身體。而身體鍛煉能讓人強(qiáng)壯和放松，重新注入能量，讓學(xué)習(xí)更加有效率。所以，高中生應(yīng)該鍛煉身體。他們可以做些運(yùn)動(dòng)，例如打籃球或者踢足球、跑步、游泳等等。
