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.

The stages of sleep take on ____

A) an irregular aspect.

B) a regular aspect

C) a punctual aspect

D) a similar aspect

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.

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.

in it the dreamer takes actions and reacts.During dreams the body is asleep but the thinking part of the brain is wide awake.In fact, it is more active than it sometimes is when the body is awake.

One group of researchers decided to see what would happen if they stopped people from dreaming.As soon as the electroencephalograph (脑电图仪) registered a dream pattern, researchers woke the dreamer.They did this all night for several nights, every time the person started to dream.

The experiment revealed that people who were unable to dream became nervous, easily upset, and hungrier.As soon as they were able to sleep without interruptions they lost their nervousness and became normal again; however, they then had more dreams than usual.It was as if they were catching up on their dreams.

To check these findings, the researchers carried on a control experiment.Again they woke people during the night, but during non-dreaming periods.These people did not change their daytime behavior.And when they were allowed to sleep without interruptions (打断), the number of their dreams did not increase.

Experiments like these have caused scientists to ask if dreams serve a purpose.Researchers know, for example, that some people who go for days without sleep will suffer from hallucinations (幻觉).Certain people even begin to show signs of mental illness.Some researchers believe that people become this way because they cannot have their usual numbers of dreams.According to this theory dreaming helps people to lead normal lives.

Hints for Reading Practice

(1) Most of us can find 15 minutes or half an hour each day for some regular activity. For example,one famous surgeon always spent 15 minutes reading something before he went to sleep each day. Whether he went to bed at 10 p.m. or 2:30 a.m. made no difference.

(2) "Speed Reading" courses teach students how to read more quickly. In such courses, teachers often ask students to find out how many words a minute he is reading. You can do this too:look at your watch every 5 or 10 minutes and write down the page number you have reached.

(3)Obviously, you should not increase your reading speed if you do not understand what you are reading. If you find something you don&39;t understand in the book, or you cannot remember clearly the details of what is said, why not read the chapter again？

(4)Take four or five pages of an interesting book you happen to be reading now. Read these pages as fast as you can. Don&39;t worry about whether you understand or not. If you keep doing this "lightning speed" reading for a period of time, you will usually find that your normal speed has increased.

(5) Most paragraphs in an article have a topic sentence that expresses the central idea. The opening paragraph often suggests the general direction and content of the article, while paragraphs that follow expand or support the first. The closing paragraph often gives a summary of the most important points of the article.

Paragraph 2__________ 查看材料

A.The organization of an article

B.Check your reading speed

C.A way to increase your reading speed

D.Check your understanding

E.Read something every day

F.Read extensively

n out. Today, however, we needn't worry about feeling pain during the operation. The sick person falls into a kind of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new. It is not many years since a man who had to have operation felt all its pain.

Long ago, operation had usually to be done while the sick man could feel everything. Soon after 1770, Josept Priestley discovered a gas which is now called "laughing gas". Laughing gas became known in America. Young men and women went to parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells, noticed that people didn't seem to feel pain when they were using this gas. He decided to make an experiment on himself. He asked a friend to help him.

Wells took some of the gas, and his friend pulled out one of Well's teeth. Wells felt no pain at all.

As he didn't know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out.

Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.

1.It is not long since a man felt all the pain while being operated.

2.Long ago, when the sick man was operated on, he could feel nothing.

3.Using the laughing gas, the people seemed to feel pain during the operation.

4.If a man took less laughing gas than he should have when an operation went on, he still felt pain.

5.One who took too much of the laughing gas would die.
