After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts(变换) back and forth from one level to the other.
Although your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend(建议) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.

A. you move restless B. you start dreaming
C. your mind stops working D. your eyeballs move quickly
50. A good title for this text might be_________
A. Dreams B. Sleep C. Good Health D. Work and Rest

When you think of all the ways your body can get hurt---falling off a bike, stepping on a nail, being bitten by a crazed dog---the aches and pains that come from sitting at a computer may not seem like much.
But more doctors are getting worried about just that. If you sit at a PC the wrong way, the nerves and muscles in your back, neck and arms can get out of line.
Ergonomics is the study of how people work and how jobs and equipment can be designed so that people are safer and more comfortable in the things they do---whether that’s working on a factory assembly line or sitting in front of a computer.
The monitor
You should not have to tilt（倾斜） your neck up or down to lock at the screen. Your eyes should be level with the top of the screen.
How far away should you sit? Reach your arm out so your fingertips just touch the screen.
The keyboard
It should be directly in front of you. Don’t unfold the legs on the bottom of the keyboard so that it tilts up toward you---it should be as flat as possible, or even tilted away from you. You want your wrists “neutral,” which means straight, not bent. This puts less strain on your nerves and muscles.
Arms should be close to the body. Don’t look at your fingers as you type. Use a document holder to hold papers at the same level as the monitor. Keep the mouse on the same level as the keyboard and close by--- so you don’t have to reach for it.
The chair
Your feet shouldn’t dangle---the blood will pool in your feet. They should rest flat on the floor, or on phone books, if necessary. Your back needs support. Roll up a towel and stick it there.
The Body
If you think of your body as a collection of right angles when you sit at a computer, you should be just fine.
Your hips should be at a 90-degree angle to your back. That takes the pressure off the spine. And your knees should bend at a 90 degree angle so your feet are flat.
