Sleep is a basic necessity of life and it is ...

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).

Food is one of the necessities in our daily life. It serves as a form of communication in two fundamental ways. Sharing bread or other foods is a common human tradition that can promote unity and trust. Food can also have a specific meaning, and play a significant role in a family or culture's celebrations or traditions. The foods we eat—and when and how we eat them—are often unique to a particular culture or may even differ between countrysides and cities within one country.

Sharing bread, whether during a special occasion or at the family dinner table, is a common symbol of togetherness. Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests. Early forms of cake were simply a kind of bread, so this tradition hits its roots in the custom of sharing bread.

Food also plays an important role in many New Year celebrations. In the southern United States, pieces of corn bread represent blocks of gold for prosperity (兴旺) in the New Year. In Greece, people share a special cake called vasilopita. A coin is put into the cake, which signifies (预示) success in the New Year for the person who receives it.

Many cultures have ceremonies to celebrate the birth of a child, and food can play a significant role. In China, when a baby is one month old, families name and welcome their child in a celebration that includes giving red-colored eggs to guests. In many cultures, round foods such as grapes, bread, and moon cakes are eaten at welcome celebrations to represent family unity.

Nutrition is necessary for life, so it is not surprising that food is such an important part of different cultures around the world.

1.According to the passage, sharing bread______.

A. can help to develop unity　　 B. indicates a lack of food

C. is a custom unique to rural areas　　 D. has its roots in birthday celebrations

2.The author explains the role of food in celebrations by______.

A. analyzing causes　　 B. making comparisons

C. using examples　　 D. describing processes

3.What is the passage mainly about?

A. The custom of sharing food.　　 B. The specific meaning of food.

C. The role of food in ceremonies.　　 D. The importance of food in culture.

Sleep is just as important as diet and exercise, and not getting enough sleep can lead to obesity, heart trouble and other health problems. Now scientists are adding more wake-up call to that list: lack of sleep damages the brain.

People who regularly have trouble falling asleep and staying asleep (one study drew the line at 6.8 hours ) show changes in brain-----actual shrinking(缩小)，in some cases--- in area important for memory and problem solving.

“We’ve always believed that we can take the weekend to catch up and be fine,” says Sigrid Veasey, a researcher in University of Pennsylvania, but that may not be the case. When she stopped mice from sleeping for 3 days, they lost 25% to 30% of the neurons (神经元) important for focused attention---- and these remaining were damaged. What’s more, these brain cells never grew again.

Clearly, something important is happening while we sleep, but exactly what sleep does for the brain has been a mystery. That’s why scientists got excited when researchers at the university of Rochester Medical Center recently offered a new theory. While observing the brains of sleeping mice, they discovered a kind of brain-cleaning system that clears away neural waste, the buildup of which is connected with Alzheimer’s.

In another study, young healthy people whose sleep was limited to 7 hours per night for one week showed damaged brain function. Scarier is that with long-lasting short sleep, you may feel fully rested. When study subjects were limited to 4 hours of sleep for 5 days, they reported feeling very tired following the first night but they didn’t get any sleepier after that.

What’s more, a 15,000 –person study found that getting an average of less than 5 hours of sleep per night for several years resulted in a decrease in memory performance equal to the brain aging 2 years.

As we all know, sleep is very important and necessary. I would love everyone to develop the following four habits to have better sleep without needing the alarm（闹钟）wake-up call.

1.If you eat much food an hour before you go to bed, your body will hate you, because your body needs time to digest while you are still awake.

2.When I hear on TV that people just need 30-minute exercise a week, I think that’s wrong. Every person should get 30-minute exercise every day. When you exercise, your body uses energy and feels tired. You have to recover from the tiredness. 3. The harder you exercise your body, the faster it falls to sleep and the better it sleeps.

Turn the TV off. There are a few shows I still watch, but they will never get in my way of (妨碍) sleep. The bedroom is only for sleeping and rest. 4..

5.A question to ask yourself: If I didn’t have an alarm, what time would I get up? If that time is the time you need to get up, you should probably throw away the alarm. If the time you actually get up is much later than the time you need to get up, make great changes to your way of life and the time you go to sleep. No one should need an alarm.

A. Exercise for at least 30 minutes every day.

B. Don’t eat any food 4 hours before you sleep.

C. Throw away the alarm.

D. Sleep is one of the most important things in our lives.

Enough sleep is important to health. The amount of sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups. Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgment(判断) to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day’s work.

Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation(松弛).

Ability(能力) to sleep is largely a habit. The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance(避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.

A bath at bedtime, neither hot nor cool but of body temperature, may be helpful to sleep. Sleep-producing drug(药) should never be taken except when suggested by a doctor.

1.We know from the passage　　　　 is enough for the health of a pupil.

A. equal or more than eight hours            B. seven hours or so
