     Good health is the most valuable thing a person can have, but one cannot take good health for

granted. It is important to remember that the body needs proper care in order to be healthy. There

are three things that a person can do to help stay in good shape: eat right food ,get enough sleep,

and exercise regularly.

     Proper nutrition (营养) is important for good health. Your body cannot work well unless it

receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat

plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are

very important because they provide necessary vitamins (维他命) and minerals. However, don't

over eat. It is not helpful to be overweight.

     Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel

tired and easily get angry. You have no energy. Over a long period of time a little a amount of

sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven

to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your

mind will be sharp.

     Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles,and prevents

you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise

program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most s

ports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running

and so on are good examples. Sports are not only good for your body, but they are enjoyable and

interesting, too.

     If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world

would be a happier and healthier place. We would all live to be much older and wiser.
