阅读:Sleep is part of a person's daily activity cycle. There are several different stages of sleep

Questions 26 to 30 are based on the following passage:

Sleep is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber (安睡), your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing were slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain waves will be. Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.

You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids (眼皮) as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will grow slow and regular once more, and you will slip gently back from stage 1 to stage 4 sleep — only to rise once again to the surface of near consciousness some 80 minutes later.

26.The stages of sleep take on ____.

A) an irregular aspect. B) a regular aspect C) a punctual aspect D) a similar aspect

27.Stage 4 sleep lasts ____.

A) about 80 minutes

B) about 40 60 minutes

C) about 30 munutes

D) about 20 40 minutes

28.The brain waves are the slowest during ____.

A) stage 1 C) stage 4 B) stage 2 and stage 3 D) REM sleep

29.In the second paragraph the word “dart” means ____.

A) glare B) move rapidly or suddenly C) stop moving D) gaze

30.One of the features of REM sleep is that ____.

A) there are large slow waves, though rapid for the first few minutes

B) you have the deepest sleep

C) there are no brain waves

D) the brain waves are a little fast and the brain becomes a little active

阅读材料,回答题。

When We Are Asleep

Everyone dreams, but some people never recall their dreams, or do so very rarely. Other people always wake up with vivid recollections (记忆 ) of their dreams, though they forget them very quickly. In an average night of eight hours&39;sleep, an average adult will dream for around one hundred minutes, probably having three to five dreams, each lasting from ten to thirty minutes.

Scientists can detect when someone is having a dream by using an instrument which measures the electrical waves in the brain. During dreaming, these waves move more quickly. Breathing and pulse rate also increase, and there are rapid eye movements under the lids, just as though the dreamer were really looking at moving objects. These signs of dreaming have been detected in all mammals (哺乳动物) studied, including dogs, monkeys, cats, and elephants, and also some birds and reptiles (爬行动物) .This period of sleep is called the "D" state for around 50% of their sleep; the period reduces to around 25% by the age of 10.

Dreams take the form. of stories, but they may be strange and with incidents not connected, which make little sense. Dreams are seldom without people in them and they are usually about people we know. One estimate says that two-thirds of the "cast" of our dream dramas are friends and relations. Vision seems an essential part of dreams, except for people blind from birth. Sound and touch senses are also often aroused, but smell and taste are not frequently involved. In "normal" dreams, the dreamer may be taking part, or be only an observer. But he or she cannot control what happens in the dream.

However, the dreamer does have control over one type of dream. This type of dream is called a "lucid"(清醒的) dream. Not everyone is a lucid dreamer. Some people are occasional lucid dreamers. Others can dream lucidly more or less all the time. In a lucid dream, the dreamer knows that he is dreaming.

Some people dream but cannot remember their dreams. 查看材料

In the world there are different forms of family groups. In modem western societies(社会), a family group is usually small, made up of a man, his wife, and his children. About a hundred years ago, it was usually a little larger than this. Unmarried(未婚的) sons and daughters were part of the family even after they were grown up. Now unmarried sons and daughters do not always live with their parents after they begin to work. They often live in their own houses or rooms.

In other societies, family groups are quite different. In some places, a man may have more than one wife. When two or more wives live together with their husband in the same home, brothers or sisters (or both) have the same father but different mothers. In these families the younger children sleep in their mother's rooms, but all the older boys may sleep together in a large room and all the older girls in another.

The first wife often has a special(特殊的) place in this kind of family. Her husband asks for her suggestion when he takes his other wives, and she tells them what work they must do.

As you sleep you pass __70__ a sequence of sleep states—light sleep, deep sleep and REM (rapid eye movement) sleep—that __71__ approximately every 90 minutes. The point in that cycle at which you wake can __72__ how you feel later, and may __73__ have a greater impact than how much or little you have slept. Being roused during a light phase __74__ you are more likely to wake up energetic.

SleepSmart __75__ the distinct pattern of brain waves __76__ during each phase of sleep, via a headband equipped __77__ electrodes (电极) and a microprocessor. This measures the electrical activity of the wearer’s brain, in much the __78__ way as some machines used for medical and research __79__, and communicates wirelessly with a clock unit near the bed. You __80__ the clock with the latest time at __81__ you want to be wakened, and it __82__ duly (适时地) wakes you during the last light sleep phase before that.

The __83__ was invented by a group of students at Brown University in Rhode Island __84__ a friend complained of waking up tired and performing poorly on a test. “__85__ sleep-deprived people ourselves, we started thinking of __86__ to do about it,” says Eric Shashoua, a recent college graduate and now chief executive officer of Axon Sleep Research Laboratories, a company created by the students to develop their idea.

听力原文:A new report says an estimated 50 million to 70 million Americans have sleep prob
lems. It says ninny more are suffering from lack of sleep.

A group of sleep research organizations asked the Institute of Medicine to study the problem. The institute is part of America's National Academy of Sciences. The study examined why we need sleep, the effects of sleep loss and other sleep dimmers. A fourteen-member committee carried out the study. The Institute of Medicine reported their findings earlier this month. The report says American businesses lose more than 100,000 million dollars a year because of tired workers. Some employees are too tired to report for work. They have accidents or are less productive at work. Other costs included increased visits to doctors.

Many experts say a good amount of sleep is as important to health as diet end exercise. They say most people need 7 to 9 hours of sleep each night. Less than that can interfere with mental and physical abilities. It can lead to more serious problems, including severe sleeplessness.

Researchers involved in the study axe suggesting a number of steps to help prevent sleep disorders. They suggest a campaign to inform. the public about the problem. They want increased education and training among health care workers. And they are calling for new technology to identify and care sleep problems.

Which of the following problems was not mentioned in the study?

(30)

A.The reason that people need sleep.

B.The results of sleep loss.

C.The effects of oversleeping.

D.Different kinds of sleep disorders.

When you first drift off into slumber, your eyes will roll about a bit, your temperature w
ill drop slightly, your muscles will relax, and your breathing will become quite regular. Your brain waves slow down a bit, with the alpha rhythm predominating for the first few minutes. This is the first stage of sleep. For the next 30 minutes or so, you will drift down through Stage 2 and Stage 3. The lower your stage of sleep, the slower your brain waves will be. About 40-60 minutes after you lose consciousness, you will reach the last stage. Your brain waves will show the delta rhythm. You may think that you stay at this deep stage all the rest of the night, but that turns out not to be the case. About 80 minutes after you fall into slumber, your activity cycle will increase slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids. This period of Rapid Eye Movements lasts for 8-15 minutes and is called REM sleep.

During both light and deep sleep, the muscles in your body are relaxed but capable of movement. As you slip into REM sleep, a very odd thing occurs -- most of the voluntary muscles in your body become paralyzed. Although your brain shows very rapid bursts of neural activity during REM sleep, your body is incapable of moving. REM sleep is accompanied by extensive muscular inhibition.

On the part of an average sleeper, there______of sleep in cycles.

A.is one stage

B.are two stages

C.are six stages

D.are four stages
