Are You Getting Enough Sleep?
What happens if you don’t get enough sleep? Randy Gardner, a high school student in theUnited States, wanted to find out. He designed an experiment on the effects of sleeplessnessfor a school science project. With doctors watching him carefully, Gardner stayed awake for 264hours and 12 minutes. That’s eleven days and nights without sleep!
What effect did sleeplessness have on Gardner? After 24 hours without sleep, Gardner startedhaving trouble reading and watching television. The words and pictures were too blurry(模糊).By the third day, he was having trouble doing things with his hands. By the fourth day, Gardnerwas hallucinating(产生幻觉). For example, when he saw a street sign, he thought it was aperson. He also imagined he was a famous football player. Over the next few days, Gardner’sspeech became so slurred(不清楚)that people couldn’t understand him. He also had troubleremembering things. By the eleventh day, Gardner couldn’t pass a counting test. In the middleof the test he simply stopped counting. He couldn’t remember what he was doing.
When Gardner finally went to bed, he slept for 14 hours and 45 minutes. The second night heslept for twelve hours, the third night he slept for ten and one-half hours, and by the fourthnight, he had returned to his normal sleep schedule.
Even though Gardner recovered quickly, scientists believe that going without sleep can bedangerous. They say that people should not repeat Randy’s experiment. Tests on white ratshave shown how serious sleeplessness can be. After a few weeks without sleep, the ratsstarted losing their fur(皮毛). And even though the rats ate more food than usual, they lostweight. Eventually the rats died.
During your lifetime, you will probably spend 25 years or more sleeping. But why? What is thepurpose of sleep? Surprisingly, scientists don’t know for sure. Some scientists think we sleep inorder to replenish(补充)brain cells. Other scientists think that sleep helps the body to growand to relieve stress. Whatever the reason, we know that it is important to get enough sleep.
16.Randy Gardner studied the effects of over-sleeping.
A.Right B.Wrong C.Not mentioned
17.During the experiment, Gardner slept for two hours every night.
A.Right B.Wrong C.Not mentioned
18.During the experiment, Gardner had trouble speaking clearly.
A.Right B.Wrong C.Not mentioned
19.It took four days for Gardner to recover from the effects of the experiment.
A.Right B.Wrong C.Not mentioned
20.Going without sleep is not dangerous for white rats.
A.Right B.Wrong C.Not mentioned
21.Scientists are not sure why we need sleep.
A.Right B.Wrong C.Not mentioned
22.People sleep less than they used to.
A.Right B.Wrong C.Not mentioned
The Meaning of Dreams
1 Dreams play an important role in our lives. If they can be correctly interpreted, we can cometo understand ourselves better. Here, we look at four common dreams and what theypotentially symbolize.
2 I can see their laughing faces ... laughing at me. But they aren’t as *** art. If they were,they’d be up here flying with me! This dream has both positive and negative connotations(涵义). On the positive side, the dream may express a strong desire to travel and get away fromeveryday routine. It can also be interpreted as a powerful desire to achieve. On the otherhand, this dream can mean the person has a problem or is afraid of something and they wish toescape. The dream could represent an inferiority complex(自卑情结), which the dreamerattempts to escape from by putting themselves up above others.
3 I’m moving fast now, but it’s still behind me. Doesn’t matter how fast I go, I still can’tescape. Although this is a traditional symbol of health and vitality(生命力)like the first one,it can also suggest the dreamer is trying to escape from danger. Usually, fear is the dominantemotion. By running hard, the dreamer can possibly escape the threat. However, they can alsostumble(蹒跚)or worse still stop moving altogether. This makes the fear even moreterrifying(恐怖的). One possible interpretation suggests that the person is under pressurein their everyday life.
4 I’m sweating and my heart is beating. I’m trapped in my own bed. In this dream, the personis often standing on a high, exposed place such as on the top of a tower, or on the edge of acliff. The overwhelming(强烈的)feeling changes from anxiety to a loss of control. There isnothing to stop the person, and the feeling as they go over the edge can be horrifyingly ((恐怖地)real. Fortunately, just before hitting the ground, the dreamer awakens with a sense ofenormous relief. This dream suggests that the dreamer is afraid of losing control and has afear of failure or even death.
5 The wind is pushing me and I slip. There’s nothing I can do — nothing I can hold on to. Thissymbol is associated with fear: suddenly the dreamer loses all power of movement. They tryhard to move their arms and legs, but they simply cannot. Frozen in a terrifying situation withno escape, they become more and more terrified as the seconds go by. Another frequentcontext for this dream is failing to do something in public, often something which you arenormally very good at, such as your job. Not only is this extremely embarrassing, but it alsoshows a deep-seated phobia(恐惧)of losing a job and a livelihood.
23.Paragraph 2 ______
24.Paragraph 3 ______
25.Paragraph 4 ______
26.Paragraph 5 ______
A.Dream of running hard
B.Dream of falling down

之一篇 Sprained(扭伤)Ankle
One of the most common injuries teenagers and *** s experience is a sprained ankle. A sprainoccurs when the ligaments(韧带)a joint are twisted(扭伤)and possibly torn. Ligaments arebands of fibers that hold the bones of a joint in position. A sprain can occur from a suddentwisting at the joint, or a stretching or tearing of the fibers of the ligaments. The injured areausually swells(肿胀)and becomes black and blue. Stepping off the sidewalk at the wrongangle or having one foot land in a hole while walking or running can leave you rolling on theground in pain with an ankle on fire! If you cannot walk without experiencing intense pain, youmust seek medical help. If the pain is manageable, and you can walk, here are three words tohelp you remember how to treat yourself:
■ Elevate(抬高)
■ Cool
■ Bandage(打绷带)
As soon as there is injury to that ligament, there will be a certain amount of bleeding underthe skin. Once the blood pools around the damaged blood vessels, swelling occurs. Thepressure from the swelling results in additional stress and tenderness to the region. In orderto reduce the degree of swelling, lie down as soon as possible and keep the ankle elevated sothat it is actually higher than your heart. Next, to reduce blood distribution and keep bleedingto a minimum, apply a cold pack. After 20 minutes, take the pack off, wait half an hour andthen reapply. This can be done several times a day for a total of three days.
Never leave a cold pack on for more than 20 minutes at a time. Reducing the temperature inthat area for an extended period of time signals the body to increase blood flow to raise thebody temperature! Therefore, one accidentally triggers more blood distribution to theaffected area by leaving a cold pack on for too long! Finally, bandage the ankle. Be careful notto wind it too tightly; doing so can restrict blood flow and cause harm to the entire foot.
31.A sprain is caused by
A.blood vessels being hurt in the foot.
B.constantly changing body temperature.
C.ligament fibers of a joint being twisted.
D.elevating one’s ankle.
32.The black-and-blue symptom of a sprain is due to
A.pressing one’s ankle.
B.a tight bandage.
C.applying a cold pack.
D.bleeding under the skin.
33.The word “it” in paragraph 2 (line 5) refers to
A.injury.
B.pressure.
C.ankle.
D.swelling.
34.Once the initial cold pack is removed, what is to be done?
A.Wait 30 minutes and then reapply the ice pack for 20 minutes.
B.Begin bandaging the ankle.
C.Keep the ankle in a position lower than your heart.
D.Wait 20 minutes and then reapply the ice pack for 30 minutes.
35.The main idea of the passage is to explain
A.how a sprain occurs.
B.how to treat a sprained ankle.
C.how to bandage an injured foot.
D.how to reduce the temperature of a wounded area.
第二篇 Attitudes to AIDS Now
Most people say that the USA is making progress in fighting AIDS, but they don’t know there’sno cure and strongly disagree that “the AIDS epidemic(流行)is over,” a new survey finds.
The findings, released Thursday by the Kaiser Family Foundation, reassure activists who haveworried that public concern about AIDS might disappear in light of recent news about advancesin treatment and declines in deaths.
“While people are very optimistic about the advances, they’re still realistic about the fact thatthere is no cure”, says Sophia Chang, director of HIV programs at the foundation.
The Kaiser survey, like a recent USA TODAY Gallup Poll(民意测验), does find that the numberof people ranking AIDS as the country’s top health problem has fallen. In the Kaiser poll, 38%say it’s the top concern, down from 44% in a 1996 poll; in the Gallup Poll, 29% say AIDS is No. 1, down from 41 % in 1992 and 67% in 1987.
Other findings from Kaiser, which polled more than 1.200 *** s in September and October andasked additional questions of another 1.000 *** s in Novembers:
52% say the country is making progress against AIDS, up from 32% in 1995.
51% say the government spends too little on AIDS.
86% correctly say AIDS drugs can now lengthen lives; an equal number correctly say that thedrugs are not cures.
67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24%know deaths fell.
Daniel Zingale, director of AIDS Action Council, says, “I’m encouraged that the American peopleare getting the message that the AIDS epidemic isn’t over. I hope the decision-makers inWashington are getting the same message... We have seen signs of complacency(得意).”
36.Most people in the USA believe that
A.advances have been made in treating AIDS.
B.AIDS is no longer an epidemic.
C.AIDS is killing more people than before.
D.there is still no cure for AIDS.
37.Before the findings released by the Kaiser Family Foundation, activists worried that
A.the Americans might not concern about AIDS any more.
B.the government is too optimistic about the cure of AIDS.
C.the deaths caused by AIDS may increase.
D.scientists may not find cures for AIDS.
38.The results of the Kaiser survey and those of Gallup Poll are
A.similar.
B.different.
C.both wrong.
D.both unrealistic.
39.More than 50% people in the Kaiser poll agree that
A.advances in AIDS treatment are too slow.
B.AIDS is their top concern.

First Image-recognition Software
1. Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before.
2. The new system, which was tested on photos and is now being applied to videos, shows for the first time that a machine learning algorithm (运算法则) for image recognition and retrieval is accurate and efficient enough to improve large-scale document searches online. The system uses pixel (像素) data in images and potentially video — rather than just text — to locate documents. It learns to recognize the pixels associated with a search phrase by studying the results from text-based image search engines. The knowledge gleaned (收集) from those results can then be applied to other photos without tags or captions (图片说明), making for more accurate document search results.
3. "Over the last 30 years," says Associate Professor Lorenzo Torresani, a co-author of the study, "the Web has evolved from a *** all collection of mostly text documents to a modern, massive, fast-growing multimedia data set, where nearly every page includes multiple pictures or videos. When a person looks at a Web page, he immediately gets the gist (主旨) of it by looking at the pictures in it. Yet, surprisingly, all existing popular search engines, such as Google or Bing, strip away the information contained in the photos and use exclusively the text of Web pages to perform the document retrieval. Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pixels to improve document search."
4. The researchers designed and tested a machine vision system — a type of artificial intelligence that allows computers to learn without being explicitly programmed — that extracts semantic (语义的) information from the pixels of photos in Web pages. This information is used to enrich the description of the HTML page used by search engines for document retrieval. The researchers tested their approach using more than 600 search queries (查询)on a database of 50 million Web pages. They selected the text-retrieval search engine with the best performance and modified it to make use of the additional semantic information extracted by their method from the pictures of the Web pages. They found that this produced a 30 percent improvement in precision over the original search engine purely based on text.
23. Paragraph 1 ____
24. Paragraph 2 ____
25. Paragraph 3 ____
26. Paragraph 4 ____
A. Function of the new system
B. Improvement in document retrieval
C. Publication of the new discovery
D. Problems of the existing search engines
E. Popularity of the new system
F. Artificial intelligence software created
27. The new system does document retrieval by ____.
28. The new system is expected to improve precision in ____.
29. When performing document retrieval the existing search engines ignore __ __
30. The new system was found more effective in document search than the ____
A. using photos
B. description of the HTML page
C. current popular search engines
D. document search
E. information in images
F. machine vision systems

Medical Education
In 18th century colonial America, those who wanted to become physicians either learned as personal students from established professionals or went abroad to study in the traditional schools of London, Paris and Edinburgh. Medicine was first taught formally by specialists at the University of Pennsylvania, beginning in 1765, and in 1767 at King's College (now Columbia University), the first institution in the colonies to give the degree of doctor of medicine.
Following the American Revolution, the Columbia medical faculty (formerly of King's College) was combined with the College of Physicians and Surgeons, chartered in 1809, which survives as a division of Columbia University.
In 1893 the Johns Hopkins Medical School required all applicants to have a college degree and was the first to afford its students the opportunity to further their training in an attached teaching hospital. The growth of medical schools attached with established institutions of learning went together with the development of proprietary (私营的 ) schools of medicine run for personal profit, most of which had 10W standards and poor facilities. In 1910 Abraham Flexner, the American education reformer, wrote Medical Education in the United States and Canada, exposing the poor conditions of most proprietary schools. Subsequently, the American Medical Association(AMA) and the Association of American Medical Colleges (AAMC) laid down standards for course content, qualifications of teachers, laboratory facilities, connection with teaching hospitals,and licensing of medical practitioners (开业医师) that survive to this day.
By the late 1980s the U.S. and Canada had 1,424 medical colleges recognized by the Liaison(联络) Committee on Medical Education to offer the M. D. degree; during the 1987-1988 academic year, 47,262 men and 25,686 women entered these colleges and an estimated 11,752 men and 5,958 women were graduated. Graduates, after a year of internship ( 实习期 ) , receive licenses to practice if they pass an examination given either by a state board or by the National Board of Medical Examiners.
1. In 18th century America, higher institutions of learning that taught medicine __________.
A. did not exist
B. were few in number
C. were better than those in Europe
D. were known for their teaching hospitals
2. Initially most proprietary schools of medicine in America __________.
A. had established professionals
B. had good facilities
C. had high standards
D. were in poor conditions
3. The AMA and AAMC established standards so as to __________.
A. recruit more students
B. set up more schools of medicine
C. ensure the quality of medical teaching and practice
D. prevent medical schools from making huge profits
4. After a year of internship medical graduates can start to practice __________.
A. if they have worked in a laboratory
B. if they have studied abroad for some time
C. if they have obtained an M. D. degree
D. if they have passed an examination
5. This passage is mainly about __________.
A. how medicine is taught in America
B. how medical education has developed in America
C. how the American educational system works
D. how one can become a good doctor

(41) 根据下面材料,回答题。
It is predicted that there will be 5 scientific breakthroughs in the 21st century. We'll knowwhere we came from. Why does the universe exist? To put it another way, why is theresomething instead of nothing? Since the 1920s, scientists have known the universe isexpanding, which means it must have started at a definite time in the past. They even havedeveloped theories that give a detailed picture of the evolution of the universe from the timeit was a fraction of a second old to the present. Over the next couple of decades, thesetheories will be refined by data from extraordinary powerful new telescope. We will have abetter understanding of how matter behaves at the unfathomably high temperatures andpressures of the early universe.
We'll crack the genetic code and conquer cancer. In 19th century operas, when the *** ecoughs in the first act, the audience knows she will die of tuberculosis in Act 3. But thanksto 20th century antibiotics, the once dreaded, once incurable disease now can mean nothingmore serious than taking some pills. As scientists learn more about the genetic code and theway cells work at the molecular level, many serious diseases--cancer, for one- will becomeless threatening. Using manufactured "therapeutic" viruses, doctors will be able to replacecancer causing damaged DNA
with healthy genes, probably administered by a pill or injection.
We'll live longer (120 years?) If the normal aging process is basically a furious, invisiblecontest in our cells- a contest between damage to our DNA and our cells ability to repair thatdamage- then 21st century strides in genetic medicine may let us control and even reversethe process. But before we push scientists to do more, consider: Do we really want to live ina world where no one grows old and few children are born because the planet can hold onlyso many people?
Where would new ideas come from? What would we do with all that extra time?
We'll "manage" Earth. In the next millennium, well stop talking about the weather but willdo something about it. Well gradually learn how to predict the effects of human activity onthe Earth,its climate and its ecosystems. And with that knowledge will come an increasingwillingness to use it to manage the workings of our planet.
We'll have "a brain road map". This is the real "final frontier" of the 21st century: The brainis the most complex system we know. It contains about 100 billion neurons (roughly thenumber of stars in the Milky Way), each connected to as many as 1,000 others. Early in thenext century, we will use advanced forms of magnetic resonance imaging to producedetailed maps of the neurons in operation. We'll be able to say with certainty which ones areworking when you read a word, when you say a word, when you think about a word, and soon.
The sentence "In 19th century operas, when the *** e coughs in the first act, the audienceknows she will die of tuberculosis in Act 3" means__________.
A: there was not antibiotics at that timeB: tuberculosis was a terrible disease that couldn't be cured during 19th centuryC: the health of the *** e was very poorD: this was a common situation in the 19th century operas
答案:B
解析:
细节题。题干 :句子“在19世纪的戏剧中,如果女主角在之一幕开始咳嗽,
