    It is no doubt that health is the most important thing in our life.As a Chinese proverb go, “Health is blessing”.Should we be always ill in bed, how can we enjoy life?

    To keep healthy, we must develop a healthy way of life.First of all, we should keep on doing sports on a regularly basis, because it can strengthen both our body and mind, refresh ourselves and making us work more efficiently.Secondly, we must keep balanced diet to provide our body with various nutrition we need, but we should refuse junk food.Remember, it is through the mouth where diseases enter into our body.Thirdly, a good sleep is also vital to our health.Stay up too late at night often results in poor health.As middle school students, we need better sleep to do better in our lessons.
