Early to bed and early to rise makes a man healthy，wealthy and smart.
    The saying（諺語）means that we should go to bed early at night and get up early in the morning.If we do，we shall be healthy.We shall also be rich and smart.
    Is this true？Maybe it is.The body must have enough sleep.Children of your age need ten hours' sleep every night.If you go to bed late，you can't have enough sleep.Then you can't think carefully and you can't do well in your schoolwork.
    Some people go to bed late at night and get up late in the morning.This is not good for them.We should go to sleep early.When the daylight comes，we should get up.This is the time for exercise.If the body is not used，it will become weak.Exercise keeps it strong.
    Exercise helps the blood（血液）to move around inside the body.Blood takes nutrition（營養(yǎng)）to all parts of our bodies.The brains（大腦）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.Without air we will die.Get up early in the morning and we can have lots of clean，fresh air.That will keep us healthy and happy.
