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 previous day.

The rest that you get while sleeping enables 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 muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.

Although your mind slows down，from time to time you will dream. Scientists who study sleep say 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(推荐）breathing very

deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that the counting sheep will put you to sleep!

Henry Ford was the first one to build cars which were fast, reliable(可靠的)and cheap. He was able to sell millions of them because he “mass-produced” them. That is, he made a great many cars of exactly the same type.

Henry Ford’s father had hoped that his son would become a farmer，but the young man did not like the idea and went to Detroit where he worked as a mechanic(技术 ). By the time he was twenty-nine, in 1892，he had built his first car. The first mass-produced car in the world, the famous “Model T” appeared in 1908—five years after Henry had started his great Ford Motor Company(公司）• This car proved to be so popular that it remained unchanged for twenty years.
