Sleep Sleep is part of your daily activity cycle, but there are several different types or stages of sleep and they too occur in cycles. If you are an average sl eeper, your sleep cycle will go something like this: When you first drift off into sleep your eyes will roll about a bit, your te mperature will drop slightly, your muscles will relax, and your breathing will s low and b***me quite regular. Your brain waves slow down a bit too. This is cal led Stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift dow n through Stage 2 and Stage 3 sleep. The lower your stage of sleep, the slower y our brain waves will be. Then, about 40-60 minutes after you lose consciousness, you will have reache d the deepest sleep of all. Your brain waves will show the delta rhythm. This I s Stage 4 sleep. You may think that you stay at this deep fourth stage all the rest of the ni ght, but that turns out not to be the case. Instead, about 80 minutes after you fall into sleep your activity cycle will increase slightly. The delta rhythm w ill 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 s omething 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 c apable of movement. However, as you slip into REM sleep, a very odd thing occurs ? Most of the voluntary muscles in your body b***me paralyzed. Although your b rain shows very rapid bursts of neural activity during REM sleep, your body is I ncapable of moving.

Hearing Damage Doctors have known for a long time that extremely loud noises can cause he aring damage or loss. The noise can be the sound of a jet airplane or machines I n factories or loud music or other common sounds found at home and at work. A pe rson only needs to hear the noise for little more than one s***nd to be affected. An American scientist has found that using aspirin can increase the tempor ary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them dif ferent amounts of aspirin for different periods of time, then he tested their he aring ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did no t use aspirin. The hearing loss was about two times as great. The scientist said millions of persons in the United States use much larger amou nts of aspirin than were used in his experiment.
26、He said these persons face a se rious danger of suffering hearing loss from loud noise.Doctors have long known that____
A.one may b***me deaf when he hears a loud noise.
B.loud noises can cause damage to the hearing of young people only.
C.one may lose his hearing when he hears a terribly loud noise.
D.common sounds at home are not harmful to the ear.
27、(同26题)This passage suggests that one’s hearing____
A.will be damaged even if he has heard a loud noise for less than one s***nd.
B.will be damaged even if he has heard a loud noise for only little more than one snd.
C.will not be damaged if he has heard a loud noise for only little more than one s***nd.
D.will not be damaged if he has little more than one s***nd to get ready.
28、(同26题)One conclusion you can draw from this passage is that aspirin____
A.should never be taken more than four grams.
B.can damage one’s hearing when it is given more than four grams daily.
C.makes hearing damage from loud noise worse.
D.always increases hearing loss by two times.
29、(同26题)Millions of Americans are in danger of suffering hearing loss because they____
A.often take air trips.
B.like listening to loud music.
C.have too much loud noises at home and at work.

Dreams Let us begin by saying what does not cause our dreams. Our dreams do not com e from "another world". They are not messages from some outside source. They are not a look into the future, either. All our dreams have something to do with our emotions, fear, longings, wishe s, needs and memories. But something on the "outside" may affect what we dream. If a person is hungry, or tired, or cold, his dreams may include a feeling of th is kind. If the covers on your body, such as a blanket, have slipped off your be d, you may dream that you are sleeping or resting on the ice or snow. The materi al for the dream you will have tonight is likely to come from the experiences yo u have today. So the subject of your dream usually comes from something that has effect on you while you are sleeping and it may also use your past experiences and the wi shes and interests you have now. This is why very young children are likely to d ream of fairies, older children of school examinations, hungry people of food, h omesick soldiers of their families, and prisoners of freedom. To show you how that is happening while you are asleep and how your wishes o r needs can all be joined together in a dream, here is a story of an experiment. A man was asleep and the back of his hand was rubbed with absorbent cotton. He would dream that he was in a hospital and his charming girl friend was visiting him, sitting on the bed and feeling his hand softly. There are some scientists who have a special study of why we dream, wha t we dream and what those dreams mean. Their explanation of dreams, though a bit reas onable, is not accepted by everyone, but it offers an interesting way of dealing with the problem. They believe that dreams are mostly expressions of wishes tha t did not come true. In other words, a dream is a way of having your wishes carr ied out.
31、The word \!material" (para. 2) can be best replaced by____
A.wish.
B.source.
C.message.
D.cause.
32、The word \!it" (para. 3) refers to the____
A.dream.
B.sleep.
C.feeling.
D.subject.
33、It is implied in the passage that____
A.our dreams cannot predict correctly what may happen to us in the future.
B.our dreams can be anything except past experiences.
C.one is most likely to feel cold while sleeping without a blanket.
D.one with poor memory had fewer dreams than people with a good memory.
34、According to the experiment described in the passage, the man’s dream was caused by____
A.what the back of his hand was feeling at the moment.
B.his fear of an operation.
C.his girl friend he has just visited.
D.the hospital in which he was treated.
35、According to the writer, the explanation of dreams that some scientists made____
A.is considered interesting, but meaningless.
B.gives a good answer to the question why we dream.
C.has some value, though not fully convincing.
D.has been proved by the findings of their studies.

Hunger Hunger around the world can be reduced 50 percent by the end of the 1990s. That is the conclusion of scientists and others who met in Bellagio, Italy, sev eral months ago. The people at the meeting were experts on hungers. They reporte d that at least five hundred million persons in the world suffer from hunger. Th ey noted that several nations still have severe shortages of food. But, the expe rts said, there is progress. For example, China and India have reduced hunger sh arply in recent years, and studies have shown which methods work best at reducin g hunger in other parts of the world. The experts meeting in Italy urged public officials and aid groups to take four steps to reduce hunger. The first step is to end mass hunger of famine. They said neutral internat ional organizations should protect civilian food supplies in areas at war. They also said nations should improve their methods of sending food to emergency loca tions . The s***nd step is to produce more food for the world’s poorest families. The best way is with more modern farming methods. The green revolution made it p ossible for India and other nations to greatly increase harvests, yet these farm ing methods are far from perfect. They do not work everywhere, and they can caus e environmental damage. They also must create programs that bring food directly to the very poor. The third step is to protect mothers and young children against food short ages. The experts said mothers and young children suffer the most from hunger. M any lives can be saved by making sure they are the first to get assistance. Finally, the experts urged efforts to overcome two serious medical problem s linked to food shortages. The first is a lack of iodine. One hundred ninety mi llion persons suffer from goiter and other illnesses because they get too little iodine. The other problem is even more widespread. It is a lack of vitamin A. B oth iodine and vitamin A can be supplied. The experts meeting in Bellagio, Italy, said taking these four steps would c ut world hunger in half by the beginning of the next century.
