Sleep is something we all do. But some people need to sleep more than others. Babies sleep most of the time. Children in school sleep about ten to twelve hours a night. Most grown-ups sleep only seven or eight hours.      

All parts of our bodies have to rest after they work. Our arms need a rest after we lift heavy things. When we run fast, our legs work hard. They get tired. We have to rest them. Our brains work hard, too.     72      We can sit quite still and rest our arms and legs. But our brains aren’t resting. They go right on thinking as long as we are awake.

Our brains slow down a bit when we sleep and dream.    Instead of thinking wide-awake thought, our brains make up dreams. Some dreams are very pleasing. Some are not. Most of the time we forget them when we wake up.

Scientists have tried to find out what would happen if people were not allowed to sleep. They asked some people not to go to bed. The people stayed up all night and all the next day. They stayed up the next night, too and the day after. They played games. But they made mistakes. They forgot things.      . The people grew rude and mean. They became angry with their friends. Finally they were too tired to stand up. The moment they sat down, they fell asleep.

Scientists found that if people are not allowed to sleep, they act in an unusual way.

        But we do know that we need it to stay well.

So tonight have a good sleep. Lie down under the covers. Shut your eyes. Let your thoughts travel about. Soon you’ll stop thinking. You’ll be asleep.

A. But even as we sleep our brains are doing some work.

B. It was hard for their tired brains to work.

C. When we are awake, they help us pay attention to the world around us.

D. No one knows quite surely why sleep is so good for us.

E. Good sleep helps to improve one’s memory.

F. But babies, children and grown-ups ----all of us need to have our sleep.

    Everyone has got two personalities—one is shown to the world and the other is secret and real. You don’t show your secret personality when you are awake because you can control your behavior, but when you are asleep, sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.

  If you go to sleep on your back, your are a very open person. You normally trust people and you are easily influenced by fashion or your new ideas. You don’t like to upset people, so you never express your real feelings. You are quite shy and you aren’t very confident.

  If you sleep on your stomach, you are a rather secretive person. You worry a lot and always easily get upset, you are very stubborn, but you aren’t very ambitious (有野心的). You usually live for today not tomorrow. This means you enjoy having a good time.

Nothing is more frustrating than not being able to sleep, tossing and turning （翻来覆去）. Your mind is racing, going over everything that happened that day. Night noises keep you awake. What can you do? Here are some things you can do to help you to fall asleep.

Sleep only when sleepy

This reduces the time you are awake in bed.

If you can’t fall asleep within 20 minutes, get up and do something boring until you feel sleepy.

Don’t expose yourself to bright light while you are up. The light tells your brain that it is time to wake up.

Don’t take naps

This will ensure that you are tired at bedtime. If you just can’t make it through the day without a nap, sleep less than one hour, and take a nap before 3 p.m.

Get up and go to bed at the same time every day

Even on weekends! When your sleep cycle has a regular rhythm, you will feel better.

Regular exercise can help you sleep well, but the time to do exercise is important. Exercising in the morning or early afternoon will not interfere (干扰) with sleep.

Have a snack before bedtime

If your stomach is too empty, that can interfere with sleep. However, if you eat a heavy meal before bedtime, that can interfere as well. Have a warm glass of milk.

Take a hot bath 90 minutes before bedtime

A hot bath will raise your body temperature, but it is the drop in body temperature that may make you feel sleepy.
