健康是工作和学习的根本。
Health is most important for any of us. In order to stay healthy， we need some common knowledge.
Firstly， pay attention to the diet. We should eat lots of fruit and vegetables， be- cause they are rich in fiber and low in fat. As a proverb says，“An apple a day keeps the doctor away.”
So fruit is good for health. Don‘t have a lot of food that contains too much fat，such as butter. Meanwhile， sweets shouldbe eaten in proper quantity， because too much sugar does harm to us. Don’t drink too much coffee， either.
Secondly， exercise is necessary. Regular ex- ercise can help us keep from getting fat. People who do running every day usually have stronger hearts than who don‘t. Finally， form good living habits. We should sleep for about 8 hours at night， and never work too hard. Over work and little sleep will lead to illness. What’s more， stay away from cigarettes.
These are the things we should pay atten- tion to so as to stay healthy.
