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 (放松) 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 of sleep to the other.Though 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.1 The text suggests that not getting enough sleep might make you _.A. suffer from poor health B. feel tired and nervousC. dream more often D. breathe quickly2.

It is present in the body in a very small amount, but it makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys, formerly with the United States Air Force, noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate (硫酸盐) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein (蛋白质) foods, such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these foods. Food markets should add these elements so that more people could get needed amount of these necessary matters.5.

Today, however, we need not worry about feeling pain during the operation. The sick person falls into a kind of sleep, and when he awakes the operation is finished. But these happy conditions are fairly new. It is not many years since a man who had to have operation felt all its pain.Long ago, operation had usually to be done while the sick man could feel everything. The sick man had to be held down on a table by force while the doctors did their best for him. He could feel all the pain if his leg or arm was being cut off, and his fearful cries filled the room and the hearts of those who watched.Soon after 1770, Joseph Priestly discovered a gas, which is now called “laughing gas”. Laughing gas became known in America. Young men and women went to Parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells noticed that people did not seem to feel pain when they were using the gas. He decided to make an experiment on himself. He asked a friend to help him. Wells took some of the gas, and his friend pulled out one of Wells teeth. Wells felt no pain at all. As he did not know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out. Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.13.
