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.

Sleep is a serious business for China’s education authorities. Yu Jianwei, an official with the National People’s Congress Internal and Judicial Affairs Department, said that according to a survey, at least 30 million students under the age of 17 have suffered from a variety of emotional and behavioral problems. The number of people under the age of 18 in China is more than 300 million.

    As early as in 1994, the National Educational Committee (the predecessor of the Ministry of Education) issued a document to guarantee sleep for students. On June 1, 2007, the revised law On the Protection of Minors stated that schools and parents must ensure that primary and secondary school students get enough sleep.

    The Educational Ministry regulates the amount of homework students are given and also dictates that teachers are not allowed to occupy students' spare time, including week-ends and vacations, with extra classes.

    In 2008, schools in three districts in Shanghai began asking students to arrive half an hour later, and replaced the original morning reading time with physical activity.

    In addition to Shenyang, many other provinces and cities have introduced measures to ensure primary and secondary school students get more sleep.

Sleep is a basic necessity of life and it is as important to our health as air, food and water. When we sleep well, we wake up feeling energetic, alert and ready to face daily challenges. When we don’t every part of our lives can suffer.

A survey made by the 2002 National Sleep Foundation (NSF) in America found that 74 percent of American adults are experiencing a sleep problem a few nights a week or more and 39 percent get less than 7 hours of sleep each night and want to have a sleep during the day.

Getting enough continuous quality sleep influences how we feel and perform next day. Getting enough sleep refers to the amount of sleep you need not to feel tired next day. Although sleep experts generally recommend an average of 7-9 hours each night, some people can get along with less while others need as many as ten hours to feel energetic next day. Sleep requirements vary(变化)over the life cycle. Newborns and babies need a lot of sleep and have several periods of sleep throughout a 24-hour time period. Teenagers’ sleep patterns turn to a later sleep-wake cycle, but they still need around 9 hours of sleep. Throughout adulthood, even as we get older, we need 7-9 hours of sleep. Sleep patterns may change, but the need for sleep remains the same.

According to the 2002 poll. Over 80 percent of American adults believe that not getting enough sleep leads to poor performance at work, risk of injury, poor health and difficulty getting along with others. Often, people become easily annoyed due to lack of sleep. Recent research suggests that lack of sleep also leads to approximately 100,00 sleep-related traffic accidents each year and results in 1,500 deaths.

If you are having sleep problems, turn to a sleep diary published by the National Sleep Foundation. A sleep diary helps you examine some of your health and sleep habits so that you and your doctor can find some reasons for poor sleep. Establishing a regular bed and wake-up schedule may also help you sleep well. Besides, talking to your doctor or a sleep specialist is of great help. Most sleep disorders can be successfully treated once properly diagnosed(诊断).
