All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.

Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for mainly sleep. TVs, computers and other things should not be in your bedroom if at all possible.

Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.

Establish a pre-bedtime rule that will help focus you on sleep. You can try meditation（沉思）,reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is the best for you.

Things such as room temperature, noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences（干扰）.

1. According to the author, ________.

2.If you have sleep problems, __________.

3.The following sentences are true EXCEPT ______.

4.The main idea of the last paragraph is _______.

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 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 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 to the other.

Although 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.

49. During REM, ______

A. you move restless                                         B. you start dreaming

C. your mind stops working                                         D. your eyeballs move quickly

50. A good title for this text might be_________

A. Dreams                     B. Sleep                C. Good Health      D. Work and Rest

We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating(交替) with some 16-17 hours' wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified.
　　The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed（颠倒的） routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts(轮班) are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently.
　　The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence (发生率) of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work.
　　This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the pressure of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperature at two-hour intervals(间隔时间) throughout the period of wakefulness, it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice.
1.The main problem of the round-the-clock working system lies in　　　　　 .

A. the inconveniences brought about to the workers by the introduction of automation

B. the disturbance of the daily life cycle of workers who have to change shifts too frequently

C. the fact that people working at night are often less effective

D. the fact that it is difficult to find a number of good night workers

2.The best solution for implementing the 24-hour working system seems to be　　　　　 .

A. to change shifts at longer intervals.

B. to have longer shifts

C. to arrange for some people to work on night shifts only

D. to create better living conditions for night workers

3. It is possible to find out if a person has adapted to the changes of routine by measuring his body temperature because　　　　　 .

A. body temperature is higher when the cycle of sleep and wakefulness alternates

B. body temperature changes when he changes to night shift or back

C. the temperature reverses when the routine is changed

D. people have higher temperatures when they are working efficiently

4.Which of the following statements is NOT TRUE?

A. Body temperature may serve as an indication of a worker's performance.

B. The selection of a number of permanent night shift workers has proved to be the best solution to problems of the round-the- clock working system.

C. Taking body temperature at regular intervals can show how a person adapts to the changes of routine.

D. Disturbed sleep occurs less frequently among those on permanent night or day shifts.

高三英语单项填空简单题查看答案及解析

People often think that blue light before bedtime can make it harder to sleep. It’s true that the screens on phones, computers and televisions send out plenty of blue light. But if you’re focused on blue light as a major problem affecting your sleep or your eye health, it’s time to look at it from another aspect.

As Philip Yuhas, a professor of vision, writes at The Conversation, blue light isn’t a uniquely technological evil. It’s part of sunlight, and your eyes are exposed to plenty of it all the time. You’re fine. There are studies in mice that have found blue light can damage their eyes, but mice are nocturnal creatures (夜行动物) whose eyes are different from ours. The pigments (色素) and the lenses (晶状体) of our eyes actually block blue light fairly well—so in a sense, we already have built-in blue blocking protection.

Adding more protection isn’t likely to help, though. You can buy glasses and screen filters (滤光片) that block blue light, but Yuhas points out they are probably a waste of money. These products do not block out much blue light. The leading blue-blocking anti-reflective coating, for example, blocks only about 15% of the blue light that screens send out. You could get the same reduction just by holding your phone another inch from your face.

The American Academy of Ophthalmology doesn’t recommend blue-blocking products, either. Instead, if you’re concerned about your eye health or your ability to get to sleep on time, you already know what to do.

Put the screens away at bedtime. Read a book or find something else to do. While you’re using screens, take a 20-second break every 20 minutes to look at something 20 feet away (the “20-20-20” rule). If you get dry eyes when you look at screens for a long time, use eye drops labeled artificial tears.

1.What do people often think of blue light?

A.It is magical and rare. B.It is the most part of sunlight.

C.It is harmful to people’s skin. D.It is a factor affecting peoples sleep.

2.What did the studies in paragraph 2 find?

A.Mice can see clearly in the dark.

B.Blue light can damage mice’s eyes.

C.Human eyes actually absorb blue light well.

D.Human eyes need extra protection against blue light.

3.What can we know about blue-blocking products according to Yuhas?

A.They block a little blue light.

B.People should buy a better one.

C.They are thought highly of by experts.

D.Most can prevent plenty of harmful lights.

4.What could be the best title for the text?

A.What will Blue Light Affect Actually?

B.Are Blue Light Really from Screens?

C.Does Blue Light Affect People’s Health?

D.Why Does Blue Light Make Sleeping Hard?

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.

In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.

Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.

The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.

The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.

Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.

1.Not enough sleep can cause obesity by ______.

A. burning more of your energy

B. making you want to eat more food

C. keeping you from doing exercise

D. helping you feel great without food

2.When you sleep 7.7 hours a night, you will ______ .

A. have your ghrelin level rise and leptin level drop

B.have your leptin level rise and ghrelin level drop

C.have your ghretin and leptin levels properly balanced

D.have your hunger increase and your weight decrease

3.You can read the findings________

A. Only on the Internet

B. only in Medicine

C. Both on the Internet and in Medicine

D. Neither on the Internet nor in Medicine
