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 state that when dreaming occurs, your eyeballs begin to move more quickly. This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!
A good title for this passage is ______.
A．Sleep
B．Good Health
C．Play and Study
D．Work and Rest
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 another. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move quickly (although your eye-lids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.

You were probably right if you thought that was caused by a lack of sleep.Dr.Home, a sleep researcher in England, studied 24 college students.One group got their normal eight hours of sleep.The other group didn’t get the smallest amount of sleep — they stayed awake all night.The next day, Dr.Home tested the students.He asked them questions that required creative and original thinking.One of the questions was “How many uses can a cardboard box be put to？”
The results？ The wide-awake students did well on the tests.The tired students did poorly.
Research has already shown that tired people can do okay on tests of routine thinking, like simple addition.But Dr.Home tested creative thinking only.
As part of his study, he offered an amount of money as a reward to the sleepy students if they did well.But even this encouragement wasn’t enough to help the students overcome their tiredness.They still did poorly.Dr.Home believes that the cerebral cortex — the part of the brain where thinking takes place — may get worn out during waking hours.Sleep may help to repair the brain overnight.Without any sleep, he emphasizes, “even if you concentrate harder, you cannot do better.”
This study gives people something to think about, especially people like hospital workers and airline pilots, who must stay awake all night and then make emergency decisions.

The study adds to a growing body of evidence that there' “an intimate relationship between the amount of sleep we get and our ability to maintain a good, healthy body weight,” says sleep expert Helene Emsellem, director of the Center for Sleep and Wake Disorders in Chevy Chase, Maryland. But Americans don't seem to be getting the message that we need seven to nine hours par night. More than 1 in 5 of us, according to a report from the Centers for Disease Control and Prevention, is getting six or fewer hours of sleep per night, on average.
So how did researchers study fat cells in the Annals paper？ Matthew Brady of the University of Chicago and a group of colleagues selected and persuaded seven volunteers to take part in the research project. They were all young, thin and healthy and agreed to sleep for eight nights in a sleep lab. “For four nights they were allowed to stay in bed for 8.5 hours a night,” says Brady. Then, a month later, they came back for four additional nights——but this time they were allowed just 4.5 hours of sleep per night. And after each visit, researchers got a sample of their fat. Brady explains that the fat cells responded significantly to the loss of sleep. “I was very surprised to be honest,” he says.
Bad things can happen when fat cells become less responsive to insulin. “Fat cells are actually your friend,” he says. “They're there to store lipids (血脂).” When lipids stay inside the cells, your body can utilize the fat when you're exercising or sleeping or going about your day. “However, when fat cells stare to become insulin resistant, the lipids star to leach out of the fat cells and rise in the bloodstream,” Brady says.

Friends often gather together at a party on New Year's Eve, and when the new year comes, all ring bells, blow' whistles, sing songs, and kiss each other. A favorite Scottish song which everyone sings together is Auld Lang Sync. The words tell of old friends and good times.
In all cultures, New Year's Day is a time when people think of new beginnings. They want to make the coming year better than the last one. Many people in the United States make New Year resolutions.

Some adults require little sleep; others need eight to ten hours in every twenty-four. Infants sleep sixteen to eighteen hours daily, the amount gradually going less as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people are repute to have required little sleep. Napoleon Bonaparte, Thomas Edison, and Charles Darwin apparently averaged only four to six hours a night.
(77) Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine; a favorite hour, a favorite bed, a favorite posture (姿势), and a formula (程式) you need to follow in order to rest comfortably.
(78)Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.
