Psychosomatic illness is the occurrence of bodily symptoms(症状) which are psychological or emotional in origin.Mind and body are not separate; one affects and is affected by the other. Who has not experienced some physical manifestation of emotional stress? Such experiences as a headache after a quarrel and urinary frequency or diarrhea before an examination are not uncommon, and for most people they are of a temporary nature. The symptoms disappear and are forgotten after the crisis has passed. No treatment may beneeded, or the patient may use simple remedies to relieve the discomfort. One person may find that a leisurely walk is the best cure for a headache; another may take aspirin.Certain conditions have been considered classic examples of psychosomatic illness: pepticulcer, eczema, colitis, and asthma. Personality profiles have been developed to describe the typical characteristics of persons who develop such illness. Another point of view is that human beings are more complex and varied in their responses than such profiles would indicate, and that the type of illness a patient develops in relation to stress varies with many additional factors, such as heredity and environment. Much remains to be learned about the relationship between stress and physical illness.Physical symptoms, such as palpitation, sweating, or disturbance of sleep, which reflect anxiety, may occur over a prolonged period. The symptoms may seem mysterious and threatening, because the patient is unaware of their cause. The patient whose heart beats more rapidly and forcefully as a manifestation of anxiety may report this symptom to his doctor, believing that something is wrong with his heart. Often the patient is not aware that he is anxious. He knows only that his heart keeps pounding for no apparent reason.Almost any symptom can have its origin in emotional stress. Some patients almost invariably have the same stress when they become anxious. One may have diarrhea, another asthma, and a third may develop hives or eczema. Some people develop two or several different symptoms; often the symptoms are experienced in an alternating fashion.The development of bodily symptoms is only one manifestation of anxiety. It may show up also symptoms that areprimarily mental, such as the inability to concentrate or to remember. Such symptom too, vary in degree. Many people occasionally experience symptoms like moodiness or depression. When such symptoms are severe or long- lasting, they interfere with the functioning of individual in daily life and with his relationship with others.Sometimes a person subconsciously develops an illness as a way of handling a desperate need, such as the need for affection. The only real cure is to satisfy the primary desire. An example is a woman who has pain in her heart, not because of organic heart disease, but because the symptom is a way of gaining, if only temporarily, the love and attention for which she longs. Her husband cannot leave her when she is so sick; her children are concerned. Her pain is just as severe as if it had a physical cause.The reality of psychosomatic illnessIs the patient with psychosomatic illness really sick, or does he merely imagine he is sick? Many people, including the families of patients and members of the health professions, believe that physical illness which is influenced by emotional stress is less real, or wholly imaginary. Acknowledging the reality of the patients' illness is important; it is the first step in helping him.Patients with psychosomatic illness are likely to be neglected. The same staff who give excellent care to other patients, not uncommonly ignore them. Some possible reasons may include the use of the term psycho as a prefix. Perhaps this conveys the idea that such patients are mentally iii, and therefore have no physical illness. Perhaps they are considered weaklings. One hears comments like, "He could snap out(克服) of it if he wanted to." Prejudice against these patients may be due to a belief that they are pretending illness in an attempt to get attention orfavors.A patient with psychosomatic illness may be confused with a malingerer, one who deliberately pretends illness in order to achieve secondary gain, such as financial compensation or excuse from work. Pretending illness is considered an unhealthy and unsatisfactory solution to the problems of life. Often it adds to the patient's difficulties, as he makes elaborate attempts to avoid detection. A malingerer can be helped sometimes to find ways of coping with difficulties. The essential difference between psychosomatic illness and malingering is that the malingerer pretends symptoms. It is a conscious process and he is aware that he is pretending to be sick. The patient with psychosomatic illness develops symptoms as manifestation of largely unconscious psychic conflicts. The symptoms are real.Condemnation(责难) of the patient with psychosomatic illness can persist despite intellectual understanding of theories about its cause. The patient can sense immediately whether those who care for him are trying to help him or not. It is important to understand that:·The patient with psychosomatic illness is really sick. He is not pretending or imagining his symptoms.·The idea that he can "snap out of it" at will is no more true than it is of those with diseases like pneumonia, whose need for care is readily acknowledged.1. The symptoms of some people with psychosomatic illness are experienced in an alternating fashion.2. Moodiness and depression are symptoms that don't last long.3. Psychosomatic sick people will stop cheating when they sense that those who care for them are belittling them.4. People with psychosomatic illness tend to be given less care than they deserve.5. Malingerers are those who pretend to be iii for some other purposes.6. The symptoms of people with psychosomatic illness are primarily mental.7. Today more and more people are suffering from psychosomatic illness.8. Such conditions as ___________ have been considered classic examples of psychosomatic illness.9. Psychosomatic symptoms may be primarily mental, such as the inability ______.10. The first and the most important step in helping the psychosomatic patients is to ______.试题详解1.Y 由题干中的关键词alternating fashion定位到第一个小标题下面第五段末句： Some people develop two or several different symptoms;often the symptoms are experienced in an alternating fashion，题目是原文的同义替换，由此得出题目说法正确。

2017年大学英语四级阅读题(一)Directions: The passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, D. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.The medical world is gradually realizing that the quality of the environment in hospitals may play a significant role in the process of recovery from illness.As part of a nationwide effort in Britain to bring art out of the galleries and into public places, some of the country's most talented artists have been called in to transform older hospitals and to soften the hard edges of modern buildings. Of the 2,500 National Health Service hospitals in Britain, almost 100 now have significant collections of contemporary art in corridors, waiting areas and treatment rooms.These recent initiatives owe a great deal to one artist, Peter Senior, who set up his studio at a Manchester hospital in northeastern England during the early 1970s. He felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience.A typical hospital waiting room might have as many as 500 visitors each week. What better place to hold regular exhibitions of art? Senior held the first exhibition of his own paintings in theout-patients waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain's first hospital artist, Senior was so much in demand that he was soon joined by a team of six young art school graduates.The effect is striking. Now in the corridors and waiting rooms the visitor experiences a full view of fresh colors, playful images and restful courtyards.The quality of the environment may reduce the need for expensive drugs when a patient is recovering from an illness. A study has shown that patients who had a view onto a garden needed half the number of strong pain killers compared with patients who had no view at all or only a brick wall to look at. 2017年大学英语四级阅读题目及答案1. According to the passage, "to soften the hard edges of modern buildings" means ______A. to pull down hospital buildingsB. to decorate hospitals with art collectionsC. to improve the quality of treatment in hospitalsD. to make the corners of hospital buildings round2. What can we say of Peter Senior?A. He is a pioneer in introducing art into hospitals.B. He is a doctor interested in painting.C. He is an artist who has a large collection of paintings.D. He is a faithful follower of hospital art.3. According to Peter Senior, ______.A. art is losing its audience in modern societyB. art galleries should be changed into hospitalsC. patients should be encouraged to learn paintingD. art should be encouraged in British hospitals4. After the improvement of the hospital environment, ______.A. patients no longer need drugs in their recoveryB. patients are no longer wholly dependent on expensive drugsC. patients need good-quality drugs in their recoveryD. patients use fewer pain killers in their recovery5. The fact that six young art school graduates joined Peter shows that ______.A. Peter's enterprise is developing greatlyB. Peter Senior enjoys great popularityC. they are talented hospital artistsD. the role of hospital environment is being recognized答案： 1. B 2. A 3. D 4. B 5. D2017年大学英语四级阅读题(二)Personality is, to large extent, inherent -- A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is improtant to the parents, it is likely to become a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. T oo many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences: remember that Pheidippides, the first marathon runner, dropped dead seconds after saying: "Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations. It is a rare schoolthat allows pupils to concentrate on those things they do well. The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into 'B's. They would needs types, and schools have an important duty to try to fit a child's personality to his possible future employment. It is top management.2017年大学英语四级阅读题目及答案1. According to the author, what factors contribute to the building of personality?A. inheritanceB. inheritance, competition and environmentC. competitionD. environment2. Which of the following statements is not true according to the author of the passage?A. Schools usually adopt severe competitive policies.B. Students are often divided by competition results.C. School is place where children cultivate their characteristics.D. The stronger desire for winning, the better.3. The phrase "soak up" is closest in meaning to ______.A. pull upB. take upC. take inD. pull in4. What attitude does the author hold toward examinations in schools?A. positiveB. negativeC. doubtfulD. neutral5. What suggestion does the author make concerning the management of schools?A. All students be made into competitive A types.B. A child's personality be considered in regard to his possible future job.C. All students be changed into B characteristics.D.

In a 27　of 14 studies that looked at physical activity and academic　28　, investigators found that the more children moved, the better their grades were in school, 29　in the basic subjects of math, English and reading. The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to 30　on smaller budgets. The arguments against physical education have included concerns that gym time may be taking away from study time.

Reading comprehensionSection APassage one（1）When I was a young girl living in Ireland, I was always pleased when it rained, because that meant I could go treasure hunting. What’ sthe connection between a wet day and a search for buried treasure? Well, it’ s quite simple. Ireland, as some of you may already know, is the home of Leprechauns –little men who possess magic powers and, perhaps more interestingly, pots of gold.（2） Now, although Leprechauns are interesting characters, I have to admit that I was moreintrigued by the stories of their treasure hoard. This, as all of Ireland knows, they hide at the end ofthe rainbow. Leprechauns can be fearsome folk but if you can discover the end of the rainbow, theyhave to unwillingly surrender their gold to you. So whenever it rained, I would look up in the sky andfollow the curve of the rainbow to see where it ended. I never did unearth any treasure,but I did spend many happy, showery days dreaming of what I could do with the fortune if Ifound it.（3） As I got older, and started working, rainy days came to be just another nuisance and mychildhood dreams of finding treasure faded. But for some people the dream of striking it lucky neverfades, and for a fortunate few, the dream even comes true! Such is the case of Mel Fisher. Hisdream of finding treasure also began in childhood, while reading the great literature classics“ Treasure Island” and“ Moby Dick” . However, unlike myself, he chased his dream and in the end managed to become one of the most famous professional treasure hunters of all time, and for goodreason. In 1985, he fished up the priceless cargo of the sunken Spanish ship Atocha, which nettedhim an incredible $400 million dollars!（4） After the ship sank in 1622 off the coast of Florida, its murky waters became a treasure” . The aptly trove of precious stones, gold bars and silver coins known as “ pieces-namedofeight Fisher, who rana commercial salvaging operation, had been trying to locate the underwater treasure for over 16 yearswhen he finally hit the jackpot! His dreams had come true but findingand keeping the treasure wasn’allt plain sailing. After battling with hostile conditions at sea, Fisherthen had to battle in the courts. In fact, the State of Florida took Fisher to court overownership of the find and the Federal government soon followed suit. After more than 200 hearings,Fisher agreed to donate 20% of his yearly findings for public display, and so now thereis a museum in Florida which displays hundreds of the objects which were salvaged from the Atocha.（5） This true story seems like a modern-day fairytale: a man pursues his dream throughadversity and in the end, he triumphs over the difficulties - they all live happily ever after, right? Well,not exactly. Archaeologists object to the fact that with commercial salvaging operations likeFisher ’thes, objects are sold and dispersed and UNESCO are worried about protecting ourunderwater heritage from what it describes a s “ pillaging”.（6） The counter-argument is that in professional, well- run operations such as Fisher ’s,each piece is accurately and minutely recorded and that it is this information which is more importantthan the actual object, and that such operations help increase our wealth of archaeological knowledge. Indeed, as in Fisher’case, they make history more accessible to people through museum donations and information on web sites.（7） The distinction of whether these treasure hunters are salvaging or pillaging our underwater heritage may not be clear, but what is clear is that treasure hunting is not just innocent childanymore but profitable big business. I have learnt that the end of the rainbow is beyond my reach, but in consolation, with just a click of the mouse, I too can have a share in the riches that the Atocha has revealed. As Friedrich Nietzsche so wisely said:“ Our treasure lies in the beehive ofour knowledge.”41.In Para.4, the phrase “hit the jackpot ”means ______according to thetext. A. discovered the jackpot.B. found the treasureC. broke one of the objectsD. ran a salvaging operation42.It can be concluded from Paras. 5 and 6 that _________.A. people hold entirely different views on the issueB. UNESCO ’s view is different from archaeologists ’C. all salvaging operations should be prohibitedD. attention should be paid to the find ’s educational value43. How did the author feel about the treasure from the Atocha (Para. 7)?A. She was unconcerned about where the treasure came fromB. She was sad that she was unable to discover and salvage treasure.C. She was angry that treasure hunters were pillaging heritage.D. She was glad that people can have a chance to see the treasure.Passage two（1） PAUL was dissatisfied with himself and with everything. The deepest of his love belongedto his mother. When he felt he had hurt her, or wounded his love for her, he could not bear it. Now it was spring, and there was battle between him and Miriam. This year he had a good deal against her. She was vaguely aware of it. The old feelingthat she was to be a sacrifice to this love, whichshe had had when she prayed, was mingled in all her emotions. She did not at the bottom believe she ever would have him. She did not believe in herself primarily: doubted whether she could ever be what he would demand of her. Certainly she never saw herself living happily through a lifetimewith him. She saw tragedy, sorrow, and sacrifice ahead. And in sacrifice she was proud, in renunciation she was strong, for she did not trust herself to support everyday life. She was prepared for the big things and the deep things, like tragedy. It was the sufficiency of the smallday-life she could not trust.（2） The Easter holidays began happily. Paul was his own frank self. Yet she felt it would go wrong. On the Sunday afternoon she stood at her bedroom window, looking across at the oak-trees of the wood, in whose branches a twilight was tangled, below the bright sky of the afternoon.Grey-green rosettes of honeysuckle leaves hung before the window, some already, she fancied, showing bud. It was spring, which she loved and dreaded.（3）Hearing the clack of the gate she stood in suspense. It was a bright grey day. Paul came into the yard with his bicycle, which glittered as he walked. Usually he rang his bell and laughed towards the house. To-day he walked with shut lips and cold, cruel bearing, that had something ofa slouch and a sneer in it. She knew him well by now, and could tell from that keen-looking, aloofyoung body of his what was happening inside him. There was a cold correctness in the way he puthis bicycle in its place, that made her heart sink.（4）She came downstairs nervously. She was wearing a new net blouse that she thought became her. It had a high collar with a tiny ruff, making her, she thought, look wonderfully a woman, and dignified. At twenty she was full-breasted and luxuriously formed. Her face was still like a softrich mask, unchangeable. But her eyes, once lifted, were wonderful. She was afraid of him.He would notice her new blouse.（5） He, being in a hard, ironical mood, was entertaining the family to a description of a service given in the Primitive Methodist Chapel. He sat at the head of the table, his mobile face, with theeyes that could be so beautiful, shining with tenderness or dancing with laughter, now taking onone expression and then another, in imitation of various people he was mocking. His mockeryalways hurt her; it was too near the reality. He was too clever and cruel. She felt that when hiseyes were like this, hard with mocking hate, he would spare neither himself nor anybody else. ButMrs. Leivers was wiping her eyes with laughter, and Mr. Leivers, just awake from his Sunday nap,was rubbing his head in amusement. The three brothers sat with ruffled, sleepy appearance in theirshirt-sleeves, giving a guffaw from time to time. The whole family loved a "take-off" morethan anything.44.It can be learned from the beginning that Mariam’s attitude toward love between her and Paulis ________.A. indifferentB. desperateC. pessimisticD. ambiguous45.The narration in Para. 3 tells us that Miriam had all the following feelings except _______.A. delightB. expectationC. uncertaintyD. forebearing46.Which of the following statements is correct about the family ’s response to Paul’s mockery?A. Only the parents found it entertaining.B. Every member except Marriam was amusedC. The brothers found it hard to appreciate.D. Mariam also thought it was amusingPassage three（ 1） I ’ve written this article and you’re reading it. So we are members of the same club. We’reboth literate –we can read and write. And we both probably feel that literacy is essential to our lives.But millions of people all over the world are illiterate. Even in industrialised western countries, suchas the UK and the USA, approximately 20% of the population have 'low literacy levels'. But whatexactly does that mean?（2） My parents both left school at 14. They could read and write, but except for a quick look atthe daily newspaper, reading and writing didn't play a big part in their lives. There were very fewbooks in the house. My mother was amazed because the woman who lived next door always wrotea list of what she needed before she went to the supermarket. Why couldn't she remember? Welaughed about that for weeks. Our family didn't write lists! And when I was only 14 years old myfather gave me an important letter that he'd written to the bank and asked me to check it forgrammar and spelling mistakes. And there were quite a lot. He never usually wrote letters or postcards or even Christmas cards. So when he had to write he wasn't comfortable or confident. Does that mean that my father had a 'low level of literacy'?I don't think so.（ 3） There are lots of different definitions of literacy. Some experts define it as having the reading and writing skills that you need to be independent in your everyday life. So, for example, if you can read instructions, write a cheque, fill in a form, –anything that you need to do in everyday life –then you are 'functionally literate'.（4） Other people say that you are illiterate if you think that you are illiterate. In other words, if you feel that you can't read or write as well as you would like to.（5） If you live in a society where most people are literate then you will feel ashamed or embarrassed and avoid situations in which you have to read or write. The father of a friend of mine finally admitted to his family that he couldn't read when he was 45 years old. He bought the newspaper every day and pretended to read it - and believe it or not, his family had no idea.（6） We often forget that writing is a recent invention. Many years ago, the word 'literate' meant being able to communicate well in speaking, in other words what we now call 'articulate'. Story telling was an important activity in the past and still is today in some societies. Reading was oftena co-operative activity –someone would read aloud to a group, often from a religious text such as the Koran or the Bible.（7） Only a hundred years ago, in the United States, you were considered to be literate if you could sign your name to a piece of paper. It was an important skill. You were not allowed to vote if you couldn't sign the voting register, so literacy was connected with political rights, and many people were excluded from the democratic process.（8） Nowadays we see reading and writing as being connected, but that wasn't so in the past. Many people could read, but not write. Writing was a skilled profession. If you neededsomething written then you paid an expert to write it for you.（9） And of course, rich and important people have always employed people to write things for them. Important company bosses dictated letters to their secretaries or personal assistants. And now with new computer software you can dictate directly to your computer.（10） Being illiterate can have a big effect on people's lives. For example, a study in the UK showed that people who write and spell badly are seen as careless, immature and unreliable, andoften unintelligent. So it is more difficult for them to find jobs, even when reading and writing are not necessary for the work.（11）World-wide statistics show that literacy problems are associated with poverty and a lack of political power. More women than men are illiterate. Illiterate people have worse health, bigger families and are more likely to go to prison. So literacy campaigns must be a good thing. But don't forget that an illiterate person, or someone with a low level of literacy, isn't necessarily stupid or ignorant –and may not be unhappy at all. Knowledge and wisdom isn't only found in writing.47.Why does the author give two examples in Para 2?A. To show that literacy is interpreted in different ways.B. To show that Father was more literate than Mother.C. To indicate how important reading and writing are.D.To compare the level of literacy between neighbours.48.According to the author, the following are some of the defining features of literacyEXCETT________.A. psyhchologicalB. functionalC. socialD. independent49.Which of the following statements about reading and writing is CORRECT?A. Reading and writing have always been regarded as equally difficult.B. People had to read and write well in order to be allowed to vote.C. Reading often requires more immediate interaction than writing.D. Reading and writing have always been viewed as being connected.50.What do the last two paragraphs mainly focus on ?A. Effects of illiteracy and employment problems.B. Effects of illiteracy and associated problems.C. Effects of illiteracy on one ’s personality development.D. Effects of illiteracy on women’s career development.Section B. Short answer questions. (Answer each question with no more than ten words) Passage one.51. what does This in Para. 2 refer to?It refers to the treasure hoard of Leprechauns.52.Why did Fisher have to battle in the courts after he found the treasure (Para. 4)?Because he was sued over ownership of the treasure.Passage two.53.Why did Mariam wear a new net blouse on Sunday afternoon?Because she wanted to attract Paul’s attention.54.What is the meaning of the sentence “?he would spare neither himself nor anybody else ”in Para. 5? Everyone, including himself, would become the targets of his mockery.Passage three.55.Explain the meaning of the last sentence of Para. 11 according to the context.Illiterate people may also have knowledge and wisdom.。

So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B]Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C]As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. "That way they socialize over history outside the class, which wouldn't happen without the pressure of an in-class exam," he explained. "Furthermore, in-class exams force students to learn how to perform under pressure, an essential work skill."[D]He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled "Introduction To Congress." Some colleges have what they call an "honor code," though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn't just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.[E]Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school's professors to refrain from take-home exams. "Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries," she told me. "Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention."[F]Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches "History of Broadcast Journalism" at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. "In my field, it's not what you know—it's what you knowhow to find out," says Koch. "There is way too much information, and more coming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them."[G]Students' test-form preferences vary, too, often depending on the subject and course difficulty. "I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research," says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, "I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up." Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. "If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze."[H]How students ultimately handle tests may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there are those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.[I]Yes, my advanced age must factor into the equation (等式), in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, "We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school."[J]If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, "I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test," he responded. It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class with the ticking clock overhead.[K]Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, "It is going to be a piece of cake." When the students came in, sharpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.36.Elderly students find it hard to keep up with the rapid changes in education.37.Some believe take-home exams may affect students' performance in other courses.38.Certain professors believe in-class exams are ultimately more helpful to students.39.In-class exams are believed to discourage cheating in exams.40.The author was happy to learn she could do some exams at home.41.Students who put off their work until the last moment often find the exams more difficult than they actually are.42.Different students may prefer different types of exams.43.Most professors agree whether to give an in-class or a take-home exam depends on type of course being taught.44.The author dropped out of college some forty years ago.45.Some students think take-home exams will eat up their free time.Passage OneThat people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the "first-night" effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants' brains behaved in a similarmanner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46.What did researchers find puzzling about the first-night effect?A.To what extent it can trouble people.B.What role it has played in evolution.C.What circumstances may trigger it.D.In what way it can be beneficial.47.What do we learn about Dr. Yuka Sasaki doing her research?A.She found birds and dolphins remain alert while asleep.B.She found birds and dolphins sleep in much the same way.C.She got some idea from previous studies on birds and dolphinsD.She conducted studies on birds' and dolphins' sleeping patterns.48.What did Dr. Sasaki do when she first did her experiment?A.She monitored the brain activity of participants sleeping in a new environment.B.She recruited 35 participants from her Department of Psychological Sciences.C.She studied the differences between the two sides of participants' brains.D.She tested her findings about birds and dolphins on human subjects.49.What did Dr. Sasaki do when re-running her experiment?A.She analyzed the negative effect of irregular tones on brains.B.She recorded participants' adaptation to changed environment.C.She exposed her participants to two different stimuli.D.She compared the responses of different participants.50.What did Dr. Sasaki find about the participants in her experiment?A.They tended to enjoy certain tones more than others.B.They tended to perceive irregular beeps as a threat.C.They felt sleepy when exposed to regular beeps.D.They differed in their tolerance of irregular tones.Passage TwoIt's time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling "very tired" or "exhausted", according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able to do it all -- volunteer for school parties or cook delicious meals -- and so their answer to any request is often "Yes, I can."Women struggle to say "no" in the workplace for similar reasons, including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's health as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there'sa problem that needs to be addressed immediately, resulting in a dispute over who should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem -- even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely --including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51.What does the author say is the problem with women?A.They are often unclear about the career goals to reach.B.They are usually more committed at home than on the job.C.They tend to be over-optimistic about how far they could go.D.They tend to push themselves beyond the limits of their ability.52.Why do working women of child-bearing age tend to feel drained of energy?A.They struggle to satisfy the demands of both work and home.B.They are too devoted to work and unable to relax as a result.C.They do their best to cooperate with their workmates.D.They are obliged to take up too many responsibilities.53.What may hinder the future prospects of career women?A.Their unwillingness to say "no".B.Their desire to be considered powerful.C.An underestimate of their own ability.D.A lack of courage to face challenges.54.Men and woman differ in their approach to resolving workplace conflicts in that ______.A.women tend to be easily satisfiedB.men are generally more persuasiveC.men tend to put their personal interests firstD.women are much more ready to compromise55.What is important to a good leader?A.A dominant personality.B.The ability to delegate.C.The courage to admit failureD.A strong sense of responsibility.26.K27.D28.M29.O30.A31.F32.H33.I34.C35.B36.I37.E38.C39.D40.B41.H42.G43.F44.A45.JPassage one46.D47.C48.A49.C50.BPassage two51.D52.A53.A54.C55.B2017年12月英语四级阅读真题及答案第2套选词填空We all know there exists great void (空白) in the public educational system when it comes to __26__ to STEM （Science, Technology, Engineering Mathematics) courses. One educator named Dori Roberts decided to do something to change this system. Dori taught high school engineering for 11 years.

"Why didn't you have the curiosity to go to the casino (赌场) yourself?" The implication of the question is that a more curious commissioner would have found a way to get the tape.[B]The accusation of incuriosity is one that we hear often, carrying the suggestion that there is something wrong with not wanting to search out the truth. "I have been bothered for a long time about the curious lack of curiosity," said a Democratic member of the New Jersey legislature back in July, referring to an insufficiently inquiring attitude on the part of an assistant to New Jersey Governor Chris Christie who chose not to ask hard question about the George Washington Bridge traffic scandal. "Isn't the mainstream media the least bit curious about what happened?" wrote conservative writer Jennifer Rubin earlier this year, referring to the attack on Americans in Benghazi, Libya.[C]The implication, in each case, is that curiosity is a good thing, and a lack of curiosity is a problem. Are such accusations simply efforts to score political points for one's party? Or is there something of particular value about curiosity in and of itself?[D]The journalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Your Future Depends on It, insists that the answer to that last question is 'Yes'. Leslie argues that curiosity is a much-overlooked human virtue, crucial to our success, and that we are losing it.[E]We are suffering, he writes, from a "serendipity deficit." The word "serendipity" was coined by Horace Walpole in an 1854 letter, from a tale of three princes who "were always making discoveries, by accident, of things they were not in search of." Leslie worries that the rise of the Internet, among other social and technological changes, has reduced our appetite for aimless adventures. No longer have we the inclination to let ourselves wander through fields of knowledge, ready to be surprised. Instead, we seek only the information we want.[F]Why is this a problem? Because without curiosity we will lose the spirit of innovation and entrepreneurship. We will see unimaginative governments and dying corporations make disastrous decisions. We will lose a vital part of what has made humanity as a whole so successful as a species.[G]Leslie presents considerable evidence for the proposition that the society as a whole is growing less curious. In the U.S and Europe, for example, the rise of the Internet has led to a declining consumption of news from outside the reader's borders. But not everything is to be blamed on technology. The decline in interest in literary fiction is also one of the causes identified by Leslie. Reading literary fiction, he says, make us more curious.[H]Moreover, in order to be curious, "you have to be aware of a gap in your knowledge in the first place." Although Leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we don't know, he's surely right to point out that the problem is growing: "Google can give us the powerful illusion that all questions have definite answers."[I]Indeed, Google, for which Leslie expresses admiration, is also his frequent whipping body (替罪羊). He quotes Google co-founder Larry Page to the effect that the "perfect search engine" will "understand exactly what I mean and give me back exactly what I want." Elsewhere in the book, Leslie writes: "Google aims to save you from the thirst of curiosity altogether."[J]Somewhat nostalgically (怀旧地), he quotes John Maynard Keynes's justly famous words of praise to the bookstore: "One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as curiosity dictates, should be an afternoon's entertainment." If only![K]Citing the work of psychologists and cognitive (认知的) scientists, Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work. Curiosity, he argues, is the third key factor—and a difficult one to preserve. If not cultivated, it will not survive: "Childhood curiosity is a collaboration between child and adult. The surest way to kill it is to leave it alone."[L]School education, he warns, is often conducted in a way that makes children incurious. Children of educated and upper-middle-class parents turn out to be far more curious, even at early ages, than children of working class and lower class families. That lack of curiosity produces a relative lack of knowledge, and the lack of knowledge is difficult if not impossible to compensate for later on[M]Although Leslie's book isn't about politics, he doesn't entirely shy away from the problem. Political leaders, like leaders of other organizations, should be curious. They should ask questions at crucial moments. There are serious consequence, he warns, in not wanting to know.[N]He presents as an example the failure of the George W. Bush administration to prepare properly for the after-effects of the invasion of Iraq. According to Leslie, those who ridiculed former Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the "unknown unknowns" were mistaken. Rumsfeld's idea, Leslie writes, " wasn't absurd—it was smart." He adds, "The tragedy is that he didn't follow his own advice."[O]All of which brings us back to Goodell and the Christie case and Benghazi. Each critic in those examples is charging, in a different way, that someone in authority is intentionally being curious. I leave it to the reader's political preference to decide which, if any, charges should stick. But let's be careful about demanding curiosity about the other side's weaknesses and remanding determinedly incurious about our own. We should be delighted to pursue knowledge for its own sake—even when what we find out is something we didn't particularly want to know.36.To be curious, we need to realize first of all that there are many things we don't know.37.According to Leslie, curiosity is essential to one's success.38.We should feel happy when we pursue knowledge for knowledge's sake.39.Political leaders' lack of curiosity will result in bad consequences.40.There are often accusations about politicians' and the media's lack of curiosity to find out the truth41.The less curious a child is, the less knowledge the child may turn out to have.42.It is widely accepted that academic accomplishment lies in both intelligence and diligence.43.Visiting a bookshop as curiosity leads us can be a good way to entertain ourselves.44.Both the rise of the Internet and reduced appetite for literary fiction contribute to people's declining curiosity.45.Mankind wouldn't be so innovative without curiosity.Passage OneAging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a "disease."On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments."It unties the hands of the pharmaceutical (制药的.industry so that they can begin treating the disease and not just the side effects," he said."Right now, people think of aging as natural and something you can't control," he said. "In academic circles,people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range."But if aging were recognized as a disease, he said, "It would attract funding and change the way we do health care. What matters is understanding that aging is curable.""It was always known that the body accumulates damage," he added. "The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions."Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them."There're many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease," Hayflick said. "Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years."46.What do people generally believe about aging?A.It should cause no alarm whatsoever.B.They just cannot do anything about it.C.It should be regarded as a kind of disease.D.They can delay it with advances in science.47.How do many scientists view aging now?A.It might be prevented and treated.B.It can be as risky as heart disease.C.It results from a vitamin deficiency.D.It is an irreversible biological process.48.What does Alex Zhavoronkov think of "describing aging as a disease"?A.It will prompt people to take aging more seriously.B.It will greatly help reduce the side effects of aging.C.It will free pharmacists from the conventional beliefs about aging.D.It will motivate doctors and pharmacists to find ways to treat aging.49.What do we learn about the medical community?A.They now have a strong interest in research on aging.B.They differ from the academic circles in their view on aging.C.They can contribute to people's health only to a limited extent.D.They have ways to intervene in people's aging process.50.What does professor Leonard Hayflick believe?A.The human lifespan cannot be prolonged.B.Aging is hardly separable from disease.C.Few people live up to the age of 92.D.Heart disease is the major cause of aging.Passage TwoFemale applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts. Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring (指导), and have better odds of being hired. Studies show they're also perceived as more competent than women in STEM (Science, Technology, Engineering, and Mathematics.fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too.。

新东方刘涛：2017年12月大学英语四级考试真题解析阅读部分(新东方版)

2017年12月大学英语四级考试真题解析阅读部分（第一套）各位同学大家好，2017年12月大学英语四级刚刚落下帷幕，大家肯定还存在着很多困惑，那么下面我们针对第一套真题中的阅读部分，给大家进行一下具体的解析和讲解。

一、先来看一下选词填空部分，这依然是阅读中最难的部分，但是因为分数占比仅有5%，所以不用太担心。

做题原则为：先判定词性，再判定词义。

26.K 根据some和skills判定填空处的词性为形容词，根据上下句得知此空词义应为“有优势的，较好的”。

27.D 根据填空前an urban..,确定此空词性为名词，根据and前的dirty birds判定为负面的并列，所以选负面可数名词，nuisance的意思为：令人生厌的东西。

28.M 此空后面有of引导的介宾结构，所以前后必定为从属关系，词义和手有关，而且词性为名词，所以选tip，表示指尖。

29.O 此空为形容词，而且和器官有关，前文说尽管鸽子的脑子很小很弱，而后文必须硕它们的另外器官功能很强，所以“视觉的”比较符合要求。

30.A 此处为固定搭配。

be associated with 表示前者与后者有关。

31.F rather than为肯前否后结构，前后语意相反，但词性相同，所以选ing形式的词，即，人们通常会把老鼠和传播疾病联系在一起，而不会把它们和预防疾病联系起来。

32.H 根据后句话中的中文提示（嗅觉感受器），可知老鼠的鼻子很灵敏，推导出32的词义应该和高度“敏感的”的相关。

33.I此空词性为形容词，词义根据前后文判断应该是和“小、细微的”有关。

因为后文中说“能探测出肺结核细菌”，所以“轻微的”比较符合文意。

34. C 不定式结构，所以此空为动词原形。

根据前后文，此处为“暗示”。

35.B不定式结构，所以此空也为动词原形。

根据后文，”this rat detection method”判定此处为“检测，实验”。

二、再来看一下，段落匹配题，此类占10%的分数，比较重要。

【原文】As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can perk them right up again. During vigorous exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a phenomenon called “central fatigue,” in which an imbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements effectively. It was not known, however, whether central fatigue might also affect motor systems not directly involved in the exercise itself—such as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydrate solution either with a moderate dose of caffeine—which is known to stimulate the central nervous system—or as a placebo without, during 3 hours of cycling. After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still control their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, preventing their ability to capture new visual information. The caffeine—the equivalent of two strong cups of coffee—was sufficient to counteract this effect, with some cyclists even displaying increased eye movement speeds, the team reports today in Scientific Reports. So it might be a good idea to get someone else to drive you home after that marathon.段落信息匹配36 [H] 题干：Successful team leaders know exactly where the team should go and are able to take promptaction.37 [D] 题干：Decentralisation of authority was also found to be more effective in military operations.38 [B] 题干：In many companies,the conventional form of organisation is giving way to a network of teams.39 [J] 题干：Members of poorly managed teams are easily distracted from their work.40 [G] 题干：Teamwork is most effective when team members share the same culture.41 [A] 题干：According to a report by Deloitte,teamwork is becoming increasingly popular among companies.42 [F] 题干：Some team members find it hard to agree on questions like membership and the team's purpose.43 [E] 题干：Some scholars think teamwork may not always be reliable,despite its potential to work wonders.44 [I] 题干：T o ensure employee's commitment,it is advisable to give them more flexibility as to where and how they work.45 [C] 题干：Product transitions take much less time now than in the past.扩展：大学英语四级阅读理解经验技巧大学英语四级阅读理解经验技巧1、先去看英语阅读中的问题和答案，对于重要的词语做上标记，并写上词语的意思，然后回到原文中去匹配。
