Li Hua is an English learner who want to improve his reading skills, and he rarely practices. Yesterday he came and asked us for advices. ＂Any good athlete,＂ I said, ＂who will tell you he practices hardly to get in shape and achieve high honors. Seldom we hear of any athlete becoming a champion without any effort. We consider training to be a part of the game. Once he is in shape, it is easier of an athlete to succeed. Reading skills develop the same way. Any person who reads a lot are bound to improve his reading comprehension.＂ Feeling ashamed, Li Hua made upon his mind to practice more in future.

It is clear shown that many middle school students have physical and mental problems. 68% of the students surveying have studying anxiety as well as poor eyesight too. And a larger percentage lacks sleep. 52% are short of physical exercise. 42% of the students won’t obey our parents or teachers. Personally, I think we student should balance our physical exercise and studies. Without sound body, one can’t achieve anything. However, too much attention has been paid only on studies. As a result, I suggest we are given less homework or more time for out-of-classroom activities. Only in this way can we live a happy and healthy life.
