     Early to bed, early to rise, makes a man healthy, wealthy and wise.

     This is an old English saying. Have you heard it before? It means that we must go to bed early in the

evening and get up early in the morning. If we do, we shall be healthy. We shall also be rich (wealthy) and

clever (wise).  

     Is this true? Perhaps it is. The body must have enough sleep. Children need ten hours' sleep every night.

If you do not go to bed early, you cannot have enough sleep. Then you cannot think properly (适当地)

and you cannot do your work properly. You will not be wise and you may not become wealthy!

     Some people go to bed late at night and get up late in the morning. This is not good for them. We must

sleep at night when it is dark. The dark helps us to sleep properly, When the daylight comes, we must get

up. This is the time for exercise. Exercise means doing things with the body. Walking, running, jumping,

swimming, and playing games are all exercise. If the body is not used, it becomes weak. Exercise keeps it

strong. Exercise helps the blood to move around inside the body. This is very important. The brains (大脑)

in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise,

we can think better.

      Our bodies also need air to breathe. Without air we die. We must have a lot of clean, fresh air to breathe

if we want to be healthy.
