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

eep, 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, your eyes will roll about a bit, your temperature will drop, your muscles will relax, and your breathing will 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 I 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 along, 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 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 that most dreams seem to occur.

Provided that you do not wake up during the first 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.

Which of the following does the passage mainly discuss?

A.Scientific methods of studying sleep.

B.Why humans require sleep.

C.The phases of sleep.

D.Why dreams occur during REM sleep.

Sleep

Sleep is part of your daily activity cycle, but there are several differenttypes or stages of sleep and they too occur in cycles.If you are an average sleeper, your sleep cycle will go something like this: When you first drift off into sleep your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing will slow and become quite regular.Your brain waves slow down a bit too.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 40-60 minutes after you lose consciousness, you will have reached the deepest sleep of all.Your brain waves will show the delta rhythm.This is Stage 4 sleep.

You may think that you stay at this deep fourth stage all the rest of the night, but that turns out not to be the case.Instead, about 80 minutes after you fall into sleep your activity cycle wilt increase slightly.The delta rhythm will disappear, to be replaced by the activity pattern of brain waves.Your eyes will begin to move around under your closed eyelids as if you were looking at something occurring in front of you.This period of Rapid Eye Movements lasts for some 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.However, as you slip into REM sleep, a very odd thing occurs.Most of the voluntary muscles(随意肌)in your body become paralyzed(麻痹).Although your brain shows very rapid bursts of neural activity during REM sleep, your body is incapable of moving.

Dream is a story that a person “watches”or even takes part in during sleep.Dream event
s are imaginary, but they are related to real experiences and needs in the dreamer's life.They seem real while they are taking place.Some dreams are pleasant, others are annoying, and still others are frightening.

Everyone dreams, but some persons never recall dreaming.Others remember only a little about a dream they had just before awakening and nothing about earlier dreams.No one recalls all his dreams.

Dreams involve little logical thought.ln most dreams, the dreamer cannot control what happens to him.The tory may be conf ing, and things happen that would not happen in real life.People see in most dreams, hut they may also hear, smell touch, and taste in their dreams.Most dreams occur in color.But people who have been blind since birth do not see at all in dreams.

Dreams are a product of the sleeper's mind.They include events and feelings that he has experienced.Most dreams are related to events of the day before the dream and strong wishes of the dreamer.Many minor incidents of the hours before sleep appear in dreams.Few events more than two days old turn up.Deep wishes or fears-especially those held since childhood-often appear in dreams, and many dreams fulfill such wishes.Events in the sleeper's surrounding-a loud noise, for example, may become part of a dream, but they do not cause dreams.

Some dreams involve deep feelings that a person may not realize he has.Psychiatrits often use material from a patient's dreams to help the person understand himself better.

第9题

Researchers have recently found a connection between disease and stressful situations. To
test this theory, psychologists are trying to find a link between the brain and the immune system.

The immune system in our bodies fights the bacteria and viruses which cause disease. There- fore, whether or not we are likely to get various diseases depends on how well our immune system works. Biologists used to think that the immune system was a separate, independent part of our bodies. Recently, however, they have found that our brain can affect our immune system. This discovery indicates that there may be a connection between emotional factors, such as stress or depression, and illness.

Although many doctors in the past suspected a connection between emotional factor and disease, they had no proof. Scientists have only recently discovered how the brain and the immune sys- tem function. Before this, no one could see a link between them. As a result, medical science never seriously considered the idea that psychological factors could cause disease.

Several recent studies showed a connection between stress and illness, for example, researchers went to an American military school to study the students. They found that the sick students there had a lot of academic pressure and wanted to achieve, but they were not very good students. In a similar study, researchers studied a group of student nurses and found that the nurses who developed cold sores were the ones who described themselves as generally unhappy people.

In addition to these results, which support their theory, researchers are also looking for proof that stress can damage the immune system. Researchers studied recently bereaved people, i. e. , people whose loved ones have just died, because they are more likely to become ill or die. By examining the immune system of recently bereaved people, the researchers made an important discovery. They examined some white blood cells which are an important part of the immune system. They were not functioning properly. The fact that they were not working correctly indicates that severe psycho- logical stress, such as a loved one's death, may damage an important part of our immune system.

There is still no positive proof of a connection between the immune system and psychological factors. Researchers also say that the results of the studies on bereaved people could have a different explanation. For example, bereaved people often sleep and eat less than normal, or may drink alcohol or take medication. These factors can also affect the immune system. More research is needed to clearly establish the connection between the immune system and psychological factors.

The study on the military school students indicated that ______.

A.life in the school was very stressful

B.disease could be caused by psychological factors

C.the good students were likely to fall ill

D.stress often made students unhappy
