The health of Chinese youngsters—a big concern
As a latest survey shows , the health of Chinese youngsters has greatly declined．Many Chinese students are facing a number of physical problems, such as obesity, and short-sightedness, etc．How has this situation come about?
Under the current educational system, marks seem to mean everything to students．To pass the college entrance examination, students have to spend most of their time in doing endless homework．As a result, they do not sleep or exercise enough．
To improve students’ health, we should reform the current educational system．Besides, we call for less homework, thus leaving students more time to sleep and take exercise．Only in this way can the health of youngsters be greatly improved．
