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。

英语四级考试阅读理解习题带答案满分高考写作素材篇1待人真诚，言而有信，助人为乐，拾金不昧是中华民族的传统美德，也是维系现代社会的纽带。

从小，父亲母亲就教我要讲诚信，不要撒谎，要爱亲者，不敢恶于人，敬亲者，不敢慢于人，还要助人为乐，拾金不昧。

母亲怕我不听话，就定了家规，总共十条。

一是要讲诚信，不能撒谎，二是要助人为乐，拾金不昧，三是捡到东西要交给老师，四是要为班级做好事，五是要孝敬父母亲等。

在吃饭时，不能发出声音，而且还要长辈先动筷，我们小辈才能动筷，还有就是进房时要敲门，获奖时不能太骄傲等，多么的规矩。

在我印象最深刻的是那次，那是个冬天，我和邻居约定好去后山堆雪人，那天清晨，寒气逼人，天寒地冻，最先带来冬天信息的应该是雪了，出门回头望望自己家亮着的窗户，只见玻璃上结着冰花，烟筒口流出的烟油子冻成了两根黄色的冰柱。

低头一瞧，地上有残存的积雪，白茫茫一片。

环顾四周，都是光秃秃的，没有草更没有花。

那些枯枝败叶早被无情的西北风不知刮到那个角落去了。

我感觉真的是太冷了，就又回家睡觉了，而她却在冰封雪地的后山等着我，她一直等到太阳红彤彤时才回去。

后来我才记起要去后山，可她来找我了，那时她脸冻的彤红，她说：“你一点都不讲诚信，你为什么不去?”我不知怎么解释，只好把头埋的低低的。

后来，我跟她道过歉了，她原谅了我，我觉得很惭愧，现在我知道不讲诚信的后果。

如果不是父母对我的教育，我就会不讲诚信，我觉得父母像大地一样哺育我，使我有一个良好的习惯，我就像一颗幼小的小草被大地哺育着。

满分高考写作素材篇2我们家的家风——以礼待人，父母一直告诫我：要以礼待人!家风是一条应该牢记的座右铭。

忆往昔，每逢过节，家里总有不少亲朋好友来做客，我们家自然要准备酒菜来招待。

一次我们家来了几位客人，还带来了一位小姐姐，我们两个仿佛是很久不见的老朋友似的，很快就认识并玩了起来。

很快，热腾腾的饭菜就上桌了，我们两个玩疯了，回到饭桌上时，之前的淑女模样早已不知忘到了哪，一副大大咧咧的模样，我们两个见桌上摆满了菜，说来也巧，我们两个疯跑了半天，肚子早就在“抗议”了，见四周没人，我俩便旁若无人的自顾自的吃了起来，刚吃一口，父亲从门口进来，见我在吃客人还未享用的饭菜，脸上立马“晴转多云”，一把拽起我的胳膊，把我拽到了一个没人的地方，我瞟了一眼父亲，只见他脸上不再是那种慈祥的表情了，变成了一种我从未见过的严肃，父亲向四周望望，确定没人后，既严厉又小声的说：“你刚才怎么能吃客人的饭菜呢?你想吃的话，我们可以给你做，你换位思考一下，你要是那个远道而来的客人，吃的饭居然是剩饭，你会怎么想?你自己在这里想想吧，待会吃饭时你在厨房吃那点菜吧。

大学英语四级阅读理解试题及答案（四）十六Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air.One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but itis awound that will heal. Often there is a race between the healing and the desease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly.1.Pruning should be done to ______.a.make the tree grow tallerb.improve the shape of the treec.get rid of the small branchesd.make the small branches thicker2.Trees become unhealthy if the gardener ______. a.allows too many branches to grow in the middleb.does not protect them from windc.forces them to grow too quicklyd.damages some of the small side branches3.Why is a special substance painted on the tree? a.To make a wound smoothb.To prevent disease entering a woundc.To cover a rough surfaced.To help a wound to dry4.A good gardener prunes a tree______.a.at intervals throughout the yearb.as quickly as possiblec.occasionally when necessaryd.regular every winter5.What was the author's purpose when writing this passage? a.To give pratical instruction for pruning a tree.b.To give a general description of pruningc.To explain how trees develop diseasesd.To discuss different methods of pruning.答案：babca十七On Thursday afternoon Mrs. Carke, dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the over 60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone.At six o'clock she cane home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign of forced entry.Over a cup of tea she wondered whether someone might have a key that fitted her front door-"a master key"perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that shewent out at her usual time,dressed as usual, but she didn't go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.It was just after four o'clock when the front door bell rang.Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter-box, and then a hand. The wire turned and caught around the knob on the door-lock. Mrs. Clarke raised the kettle andpoured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet.1.Mrs. Clarke looded forward to Thursday because_______. a.she worked at a club on the dayb.she said visitors on Thursdaysc.she visited a club on Thursdayd.a special visitor came on Thursday2.If someone had made a forced entery,_______.a.Mrs.Clarke would have found a broken door or windowb.he or she was still in the housec.things would have been thown aboutd.he or she would have needed a master key3.On the third Thursday Mrs. Clarke went out_______. a.because she didn't want to miss the club again b.to see if the thief was hnging about outsidec.to the club but then changed her mindd.in an attempt to trick the thief4.The lock on the front door was one which_______. a.needed a piece of wire to open itb.could he opened from inside without a keyc.could't be opened without a keyed a knob instead of a key5.The wire feel to the floor_______.a.because Mrs.Clarke refused to open the doorb.when the man's glove dropped offc.because it was too hot to holdd.because the man justwanted to get away答案：cadbd十八Many people believe the glare from snow causessnowblindnenss. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes,and evensnowblindness,when exposed to several hours of "snow light" . The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country.Rather, a man's eyes frequently find nothing to foucs on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of tsomething to look at. Finding nothing,hour after hour, the eyes never sotp searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation by producing more and fluid which covers the eyeball. The fluid coversthe eyeball in increasing quantity until vision blurs, then is obsured,and the result is total, even though temporary,snowblindness.Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape,Even the scouts themselves throw lightweight , dark colored objects ahead on which they too can focus . The men following can then see something.Their gaze is arrested. Their eyes focus on a bush and having found something to see,stop scouring thesnow-blanketed lanscape. By focusing their attention on one object at a time,the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is overcome.1.To prevent headaches, watering eyes and blindness caused by the glare from snow, dark glasses are_____.a.indispensibleefulc.ineffectived.available2.When the eyes are sore tears are produced to ________. a.clear the visionb.remedy snowblindnessc.ease the irritationd.loosen the muscles3.Snowblindness may be avoided by_______.a.concentrating to the solid white terrainb.searching for something to look at in snow-covered terrainc.providing the eyes with something to foucs ond.covering the eyeballs with fluid4.The scouts shake snow from evergreen bushes in order to _______.a.bive the men behind something to seeb.beautify the landscapec.warm themselves in the coldd.prevent the men behind from losing their way5.A suitable title for this passage would be _______. a.snowblindness and how to overcome itb.natrue's cure for snowblindnessc.soldiers in the snowd.snow vision答案：CCCAA十九Water problems in the future will become nore intense and more complex. Our increasing population will tremendously increase urban wastes,primarily sewage. On the other hand, increasing demands for water will decease substantialy the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complexchemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population,agriculture will have to be intensified. This will involve ever-increasingquantities of agricultural chemicals, From this , it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.There are two ways by which this pollution problem can be dwindled. The first relates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to " disposal and the treatment of liquid wastes, or efflunets,to permit the reuse of the water or minimize pollution upon final disposal.A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement . Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Efflunets from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketablebyproducts. Other industries are potential eonomic uses for waste products.1.The purpose of this passage is ______.a.to alert the reader to the dwindling water supplyb.to explain industrial uses of waterc.to acquaint the reader with water pollution problemsd.to demostrate various measures to solve the pollution problem2.Which of the following points is NOT INCLUDED in the passage?a.In dustrial development incudes the simplification of complex chemical processes.b.Diluting wastes needs certain amount of waterc.Demands for water will go up along with the expanding populationd.Intensive cultivation of land requires more and more chemicals3.The reader can conclued that________.a.countries of the world will work together on polution problemsb.byproducts from wastes lead to a more prosperous marketplacec.science is making great progress on increasing water suppliesd.some industries are now ,aking economic use of wastes4.The author gives substance to the passage through the use of _______.a.interviews with authorities in the field of water controlsb.opinions and personal observationsc.definitions which clarify important termsd.strong arguments and persuasions5.The words "prior to "(para.2 probably mean______. a.afterb.duringc.befored.beyond答案:cadbc二十One of the qualities that most people admire in others is the willingness to admit one's mistakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong , and you were right about that."I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain grocery store in the neighbourhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and Ibegan to remember vaguely the incident he was describing.I was about eight years old at the time, and I had gome into the store with may mother to do the weekly grocery shopping.On that particular day, I must have found my way to the dairy food department where the incident tood place.There must have been a special sale on eggs that day because there was an impressive display of eggs indozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together, so I want to work. The manager heard the moise and came rushing over to see what had happened. When he appeared, I was on my kneesinspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the culprit. He severely reprimanded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not.1.How old was the author when he wrote this article? a.about 8b.about 18c.about 23d.about 15 2.Who was to blame for knocking off the stacks of cartons?a.The authorb.The managerc.A womand.The author's mother 3.Which of the following statements is not true? a.The woman who knocked off the stacks of cartons was seriously criticized by the mananger b.The author was severely critizized by the manager. c.A woman carelessly knocked off the stacks of cartons d.It was the author who put the display back together 4.Which of the following can serve as the best title for the passage?a.Its Harder to Admit One's Mistakeb.I was once the culpritc.I remember an incidentd.A case of mistaken identity5.The tone of the article expresses the author's_______. a.admiration for the manager's willingness to admit mistakes b.anger to the manager for his wrong accusationc.indignation against the woman who knocked off the stacks of cartonsd.reget for the mistake the made in the store 答案：ccada。

四级阅读理解练习与参考答案四级阅读理解练习与参考答案：Directions：There are 2 passages in this section.Each passage isfollowed by some questions or unfinished statements.For each ofthem there are four choices marked A.，B.，C.andD..You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 56 to 60 are based on thefollowingpassage.They say that sticks and stones may break your bones，but words will never hurt you.Yet childhood bullying really can damage your long-term health.Gone are the days when bullying was considered an inevitable and ultimately harmless part of growing up—iust last month we learned that childhood bullying can lead to poorer mental health even into middle age.Now William Copeland at Duke University in Durham，North Carolina，and his colleagues have shown that it can have lingering physiological effects too.They tracked 1420 9-year-olds right through their teens.Each child was seen up to nine times during the study and quizzed about bullying.The team then measured levels of C-reactive protein in theirblood.CRP is a marker of inflammation(炎症)linked to higher risk of cardiovascular disease (心血管疾病)and problems like diabetes.“Because we were collecting biological samples throughout，we were able to look at CRP levels in subjects prior to their bullying involvement.”says Copeland.“This really gives us an idea of the changes bullying brings about.”Although CRP levels naturally rise in everyone during adolescence，levels were highest in children who reported being tormented by bullies.Even at the ages of 1 9 and 2 1，children who had once been bullied had CRP levels about 1.4 times higher than peers who were neither perpetrators nor victims.In a cruel twist，the bullies had the lowest levels of all.suggesting they didnt suffer the same health risks. They may even see a benefit from their behavior,though Copeland stresses it doesnt vindicate(辩护)their actions.“The goal would instead be to find other ways to produce this protective effect without it being at someone elses expense，”he says.Andrea Danese at Kings College London has previously shown that maltreatment during childhood can lead to higll levels of inflammation in adult life.“This new study is a helpful addition in showing that these effects extend to another important childhood stressor,”he says.He suggests that care workers could monitor levels of CRP in children having psychotherapy to see if it is helping to soothe the stress of being bullied.56.What do you know about CRP?A.It is a symbol of the inflammation.B.It is a symbol of cardiovascular.C. It relates directly to diabetes.D.It is a symbol of physiological effects caused by bullying.57.What does Copeland mean by saying“prior to their bullying involvement”(Line 2，Para.4)?A.Before the children bullied others.B.Before the children were bullied.C.In preference to the childrens bullying behavior.D.In preference to the childrens being bullied.58.What can be learned from paragraph 5?A. The levels of CRP of the children being bullied are much higher than their peers.B. CRP levels naturally rise along with the increase of age.C.The bullies are not blamed for the health risks of the bullied.D. Copeland intends to defend the benefit of the bulliesactions.59.What does Andrea Danese suggest about childhood maltreatment?A. It has nothing to do with inflammation in adult life.B.Copelands study shows nothing related to it.C.CRP is the marker of childhood abuse.D. It has an influence on Childrens CRP levels.60.What is the main idea of this passage?A.Bullying is harmless to childrens growth.B.CRP levels reflect the risks of poorer health.C.Bullying does harm to a person all through his life.D.Children once bullied have higher CRP levels than peers who are not. 四级阅读理解练习与参考答案：Questions 61 to65 are based on thefollowingpassage.Heres a case study for would-be MBAs to consider：the success of H Mart.an international supermarket chain based in New Jersey(the“H”in H Mart stands for Han Ah Reum.which means“one arm full of groceries”in Korean).Tlle first H Mart opened in Queens，New York in 1982，as a corner shop.Now there are stores in 11 states，Canada and Britain.A new one recently opened in Cambridge.Massachusetts，an affluent city outside Boston.The future looks bright for Asian supermarkets like H Mart.Eamings of Asian-American households outpace the American average.Their spending exceeds all other groups，too，according to Geoscape，a consultancy.And they spend more of their money on groceries than the average America household.But Asian delicacies can be hard to come by：few Americans are likely to see durian or bamboo shoots in their local shop.Some specialty ingredients are only to be found at a premium(高价)in up-market grocery stores，or miles away,in ethnic markets in older Asian neighborhpods.Americans have developed greater appetite for cooking and eating Asian foods，t00.In 2012 non.restaurant sales of Asian foods topped $1.5billion，according to Mintel Group.a market.research firm.Though Latin foods are a bigger market，the popularity of Asian foods is growing faster.Once strange.seeming imports like seaweed and sashimi are now fashionable eats.Though the rate of growth is expected to fall，sales are likely to keep rising.Yet most Asian grocers have not made efforts to reach new customers，says Jeffrey Cohen，an analyst at IBIS World,an industries watcher.Many shops are located in minority enclaves，and do little to market themselves to other Americans.Cramped car parks and dingy interiors fend off customers used to the bright fluorescence(荧光)of mainstream supermarkets.Ingredients labeled with poorly-translated English Can leave shoppers bamed.A few Asian grocery chains have caught on，opening stores in more diverse suburbs，paying attention to cosmetic niceties(细节)and marketing more widely.Other than H Mart，there are Califomian chains such as 99 Ranch Market and Shun Fat Supermarket，which have been expanding to the American southwest.The former was even featured in a humorous YouTube music vide —“Asians Eat Weird Things”—which has attracted more than 900，000 hits.Those weird things may not seem so weird after all.61.What makes the future ofAsian supermarkets so bright?A.High income and spending ofAsian-AmeriCalls.B. High income ofAsians and unreachable Asian foods in local American shops.C.High expenditures of Asians on grocery.D.Low earnings of the other groups.62.What are the benefits ofAmericansgrowing appetite for Asian foods?A. The increasing sales and popularity ofAsian foods.B.The expansion of Latin food market.C.The growing fondness of cooking.D.The AmeriCansgood cooking skills ofAsian foods.63.Whhat are the reasons for the unreachability ofAsian groceries to Americans?A.

：Directions：There are 2 passages in this secaon.Each passage isfollowed by some questions or unfinished statements.For each ofthem there arefour choices marked A.，B.，C.andD..You shouM decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuesaons 56 to60 are based on thefollowingpassage.When it comes to noise cancelling headphones，sometimes the best offense is a good defense.While there are plenty of active noise cancelling headphones that use a complex(and pricey)method to block distracting sounds，there are simpler ways.How about headphones with a snug fit that simply plug up your ear canals?This process is called passive isolation.Its not uncommon for a consumer faced with the choice between thedescriptors"passive"and"active"to choose the stronger-sounding technology,but great passive isolation can be just as effective and cost a lot less.The AKG K323 XS headphones($59 MSRP)are just such a pair.Sleek and portable，they produce a huge sound marked with prominent bass，supportive mids，and very healthy highs.Theyre also the best passive isolators that weve tested in a long time.Like most in-ears，the XS headphones are quite small and simply designed，available in white，blue，orange.yellow,green—the list goes on.The Android version packs a one-button universal remote，and theres also a three.button version for iOS.The XSs teeny formfactor,featherweight frame，and smalI carry case are additional on.the.go perks(特权享受).The cable is simple，but of decent quality,Its shorter than most cords—just 3.5 feet—which may or may not be desirable depending on how you use them.Ears come in all different shapes.and so do the speaker covers.AKG includes four different options：extra small，small，medium，and large.In the audio test labs.these AKGs proved to be a straight.A student.Thanks to moderate bass notes and very prominent middle and high notes，music sounds both full and balanced.From classical，to jazz，to hip hop，every genre benefits from this even-handed sound quality.Listeners will enjoy big，thumping bass that doesnt obscure subtler insmunents like violin and piano.These tiny in.ears aced distortion tests，to—you wont find one drop of unwanted or distorted sound.The K323 XS really shines.even in a crowded market.Its hard to pick which glowing attribute to praise first：The massive，well.balanced sound stage?The distortion.free listening experience?The$59 price tag?The monster isolation?Thetiny,portable design?These AKGs are simply aces(王牌)，and online sale prices of around$40 kick everything up another notch(等级).56.What can you learn from the first two paragraphs?A.All active isolators are technically complex.B.Consumers are more likely to choose active isolators.C. Passive isolation isnt as effective as the active one.D.Consumers prefer those low-priced passive isolators.57.What are the extra perks of XS?A. The tiny shape。

大学英语四级阅读习题及答案大学英语四级阅读习题(一)1、A2、D3、C4、C5、B大学英语四级阅读习题答案Acculturation, which begins at birth, is the process of teaching new generations of children the customs and values of the parents culture. How people treat newborns, for example, can be indicative of cultural values. In the United States it is not uncommon for parents to put a newborn in a separate room that belongs only to the child. This helps to preserve parents privacy and allows the child to get used to having his or her own room, which is seen as a first step toward personal independence. Americans traditionally have held independence and a closely related value, individualism, in high esteem. Parents try to instill these prevailing values in their children. American English expresses these value preferences: children should "cut the (umbilical) cord" and are encouraged not to be "tied to their mothers apron strings." In the process of their socialization children learn to "look out for number one" and to "stand on their own two feet".Many children are taught at a very early age to make decisions and be responsible for their actions. Often children work for money outside the home as a first step to establishing autonomy. Nine-or ten-year-old children may deliver newspapers in their neighborhoods and save or spend their earnings. Teenagers (13 to 18 years) may baby-sit neighbors homes in order to earn a few dollar a week. Receiving a weekly allowance at an early age teaches children to budget their money, preparing them for future financial independence. Many parents believe that managing money helps children learn responsibility as well as appreciate the value of money.21. According to this passage, the way people treat newborns _____.A) is a sign of their customsB) is an indication of their level of knowledgeC) symbolizes their social systemD) varies from culture to culture22. The expression, "to cut the cord", is used to show that _____.A) children dont like their parentsB) parents dont feel close to their childrenC) parents would not like to live together with their childrenD) independence from ones family is an important personal goal in USA23. Children who are "tied to the apron strings" _____.A) are caught in their mothers apronsB) must always wear an apron when they eatC) are very dependent on their mothersD) are independent from their parents24. American people often let their children work for money outside the home at a very early age because _____.A) children have to earn money to help the familyB) they need more moneyC) they want them to begin establishing autonomyD) children have to save money for future use25. It can be inferred from this passage that _____.A) Americans are money loversB) Americans admire independenceC) Americans are good at decision-makingD) Americans are all responsible大学英语四级阅读习题(二)Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees.The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge.Observers noted down the referees errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number.The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的) distance is about 20 meters.There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second.If FIFA, footballs international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues.He also says that FIFAs insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.21. The experiment conducted by the researcher was meant to ________.A) review the decisions of referees at the 1998 World CupB) analyse the causes of errors made by football refereesC) set a standard for football refereeingD) reexamine the rules for football refereeing22. The number of refereeing errors in the experimental matches was ________.A) slightly above averageB) higher than in the 1998 World CupC) quite unexpectedD) as high as in a standard match23. The findings of the experiment show that ________.A) errors are more likely when a referee keeps close to the ballB) the farther the referee is from the incident, the fewer the errorsC) the more slowly the referee runs, the more likely will errors occurD) errors are less likely when a referee stays in one spot24. The word “officials” (Line 2, Para. 4) most probably refers to ________.A) the researchers involved in the experimentB) the inspectors of the football tournamentC) the referees of the football tournamentD) the observers at the site of the experiment25. What is one of the possible conclusions of the experiment?A) The ideal retirement age for an experienced football referee is45.B) Age should not be the chief consideration in choosing a football referee.C) A football referee should be as young and energetic as possible.D) An experienced football referee can do well even when in poor physical condition.。

英语四级阅读题库含答案解析1.Passage OneGlobal warming may or may not be the great environmental crisis of the 21st century, but regardless of whether it is or isn’t –we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.Al Gore calls global warming an “inconvenient truth,”as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and –without major technological breakthroughs—we can’t do much about it.From 2003 to 2050, the world’s population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. but that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world’s poor to their present poverty and freeze everyone else‘s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050.No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something.”Consider the Kyoto Protocol (京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking dependence on fossil fuels or dealing with it.The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.57. What is said about global warming in the first paragraph?A) It may not prove an environmental crisis at all.B) It is an issue requiring world wide commitments. C) Serious steps have been taken to avoid or stop it.D) Very little will be done to bring it under control.58. According to the author’s understanding, what is Al Gore’s view on global warming?A) It is a reality both people and politicians are unaware of.B) It is a phenomenon that causes us many inconveniences.C) It is a problem that can be solved once it is recognized.D) It is an area we actually have little knowledge about.59. Green house emissions will more than double by 2050 because of _______.A) economic growthB) the widening gap between the rich and poorC) wasteful use of energy D) the rapid advances of science and technology60. The author believes that, since the signing of the Kyoto Protocol, ________.A) politicians have started to do something to better the situationB) few nations have adopted real tough measures to limit energy useC) reductions in energy consumption have greatly cut back global warmingD) international cooperation has contributed to solving environmental problems61. What is the message the author intends to convey?A) Global warming is more of a moral issue than a practical one.B) The ultimate solution to global warming lies in new technologyC) The debate over global warming will lead to technological breakthroughs.D) People have to give up certain material comforts to stop global warming.Passage TwoSomeday a stranger will read your e-mail without your permission or scan the Websites you’ve visited. Or perhaps someone will casually glance through your credit card purchase or cell phone bills to find out your shopping preferences or calling habits.In fact, it’s likely some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen —the 21st century equivalent of being caught naked.Psychologists tell us boundaries are healthy, that it’s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs (碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simple cannot keep a secret.The key question is: Does that matter?When opinion polls ask Americans about privacy, most say they are concerned about losing it.A survey found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is “slipping away, and that bothers me.”But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths (收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon (优惠券).But privacy does matter –at least sometimes. It’s like health: When you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it.62. What does the author mean by saying “the 21st century equivalent of being caught naked ”(Lines 3-4, Para.2)?A) People’s personal information is easily accessed without their knowledge.B) In the 21st century people try every means to look into others’secrets.C) People tend to be more frank with each other in the information age.D) Criminals are easily caught on the spot with advanced technology.63. What would psychologists advise on the relationships between friends?A) Friends should open their hearts to each other.B) Friends should always be faithful to each other.C) There should be a distance even between friends.D) There should be fewer disputes between friends.64. Why does the author say “we live in a world where you simple cannot keep a secret”(Line 5, Para.3)?A) Modern society has finally evolved into an open society.B) People leave traces around when using modern technology.C) There are always people who are curious about others’affairs.D) Many search engines profit by revealing people’s identities.65. What do most Americans do with regard to privacy protection?A) They change behaviors that might disclose their identity.B) They use various loyalty cards for business transactions.C) They rely more and more on electronic devices. D) They talk a lot but hardly do anything about it.66. According to the passage, privacy is like health in that ________.A) people will make every effort to keep itB) its importance is rarely understoodC) it is something that can easily be lostD) people don’t cherish it until they lose it2.Passage OneQuestions 57 to 61 are based on the following passage.If you are a male and you are reading this ,congratulations: you are a survivor .According to statistics .you are more than twice as likely to die of skin cancer than a woman ,and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you will die on average five years before a woman.There are many reasons for this-typically, men take more risks than woman and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor.“Men aren’t seeing doctors as often as they should, ”says Dr. Gullotta, “This is particularly so for the over-40s,when diseases tend to strike.”Gullotta says a healthy man should visit the doctor every year or two. For those over 45,it should be at least once a year.Two months ago Gullotta saw a 50-year-old ma who had delayed doing anything about his smoker’s cough for a year.“When I finally saw him it had already spread and he has since died from lung cancer”he says, “Earlier detection and treatment may not have cured him, but it would have prolonged this life”According to a recent survey, 95%of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group.“A lot of men think they are invincible （不可战胜的）”Gullotta says “They only come in when a friend drops dead on the golf course and they think”Geez, if it could happen to him.Then there is the ostrich approach,”some men are scared of what might be there and would rather not know, ”says Dr. Ross Cartmill.“Most men get their cars serviced more regularly than they service their bodies,”Cartmill says .He believes most diseases that commonly affect men could be addressed by preventive check-ups.Regular check-ups for men would inevitably place strain on the public purse, Cartmill says.”But prevention is cheaper in the long run than having to treat the diseases. Besides, the ultimate cost is far greater: it is called premature death.”57.Why does the author congratulate his male readers at the beginning of the passage?A. They are more likely to survive serious diseases today.B. Their average life span has been considerably extended.C. They have lived long enough to read this article.D. They are sure to enjoy a longer and happier live.58.What does the author state is the most important reason men die five years earlier onaverage than women?A. men drink and smoke much more than womenB. men don’t seek medical care as often as womenC. men aren’t as cautions as women in face of dangerD. men are more likely to suffer from fatal diseases59. Which of the following best completes the sentence “Geez, if it could happen to him…’(line2,para,8)?A. it could happen to me, tooB. I should avoid playing golfC. I should consider myself luckyD. it would be a big misfortune60what does Dr. Ross Cartmill mean by “the ostrich approach”(line q para.9)A. a casual attitude towards one’s health conditionsB. a new therapy for certain psychological problemsC. refusal to get medical treatment for fear of the pain involvedD. unwillingness to find out about one’s disease because of fear61. What does Cartmill say about regular check-ups for men?A.They may increase public expensesB.They will save money in the long runC.They may cause psychological strains on menD.They will enable men to live as long as womenPassage TwoQuestions 62 to 66 are based on the following passage.High-quality customer service is preached(宣扬) by many ,but actually keeping customers happy is easier said than done Shoppers seldom complain to the manager or owner of a retail store, but instead will alert their friends, relatives, co-workers, strangers-and anyone who will listen.Store managers are often the last to hear complaints, and often find out only when their regular customers decide t frequent their competitors, according to a study jointly conducted by Verde group and Wharton school“Storytelling hurts retailers and entertains consumers,”said Paula Courtney, President of the Verde group.”the store loses the customer, but the shopper must also find a replacement.”On average, every unhappy customer will complain to at least four other, and will no longer visit the specific store for every dissatisfied customer, a store will lose up to three more due to negative reviews. The resulting “snowball effect”can be disastrous to retailers.According to the research, shoppers who purchased clothing encountered the most problems. ranked second and third were grocery and electronics customers.The most common complaints include filled parking lots, cluttered (塞满了的) shelves, overloaded racks, out-of-stock items, long check-out lines, and rude salespeople.During peak shopping hours, some retailers solved the parking problems by getting moonlighting（业余兼职的）local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly, and avoided confrontation between those eyeing the same parking space.Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions.Most importantly, salespeople should be diplomatic and polite with angry customers.“Retailers who’re responsive and friendly are more likely to smooth over issues thanthose who aren’t so friendly.”said Professor Stephen Hoch. “Maybe something as simple as a greeter at the store entrance would help.”Customers can also improve future shopping experiences by filing complaints to the retailer, instead of complaining to the rest of the world. Retailers are hard-pressed to improve when they have no idea what is wrong.注意：此部分试题请在答题卡2上作答62. Why are store managers often the last to hear complaints?A Most customers won’t bother to complain even if they have had unhappy experiences.B Customers would rather relate their unhappy experiences to people around them.C Few customers believe the service will be improved.D Customers have no easy access to store managers.63. What does Paula Courtney imply by saying “…the shopper must also find a replacement”(Line 2, Para. 4)?A New customers are bound to replace old ones.B It is not likely the shopper can find the same products in other stores.C Most stores provide the sameD Not complaining to the manager causes the shopper some trouble too.64. Shop owners often hire moonlighting police as parking attendants so that shoppers_____A can stay longer browsing in the storeB won’t have trouble parking their carsC won’t have any worries about securityD can find their cars easily after shopping65. What contributes most to smoothing over issues with customers?A Manners of the salespeopleB Hiring of efficient employeesC Huge supply of goods for saleD Design of the store layout.66. To achieve better shopping experiences,customers are advised to _________.A exert pressure on stores to improve their serviceB settle their disputes with stores in a diplomatic wayC voice their dissatisfaction to store managers directlyD shop around and make comparisons between stores3. The January fashion show, called Future Fashion , exemplified how far green design has come. Organized by the New York-based nonprofit Earth Pledge, the show inspired many top designers to work with sustainable fabrics for the first time. Several have since made pledges to include organic fabrics in their lines.The designers who undertake green fashion still face many challenges. Scott Hahn, cofounder with Gregory of Rogan and Loomstate, which uses all-organic cotton, says high-quality sustainable materials can still be tough to fine . “Most designers with existing labels are finding there aren’t comparable fabrics that can just replace what you’re doing and shat your customers are used to,”he says. For example, organic cotton and non-organic cotton are virtually indistinguishable once woven into a dress. But some popular synthetics, like stretch nylon, still have few eco-friendly equivalents.Those who do make the switch are finding they have more support. Last year the influential trade show Designers & Agents stopped charging its participation fee for young green entrepreneurs(企业家) who attend its two springtime shows in Los Angeles and New York and gave special recognition to designers whose collections are at least 25% sustainable . It now counts more than 50 green designers, up from fewer than a dozen two years ago. This week Wal-Mart is set to announce a major initiative aimed at helping cotton farmers go organic: it will buy transitional(过渡型的) cotton at higher prices , thus helpingto expand the supply of a key sustainable material . “Mainstream is about to occur,”says Hahn.Some analysts(分析师) are less sure . Among consumers, only 18%are even aware that ecofashion exists, up from 6% four years ago. Natalie Hormilla, a fashion writer, is an example of the unconverted consumer, when asked if she owned any sustainable clothes, she replied: “Not that I’m aware of.”Like most consumers, she finds little time to shop, and when she does, she’s on the hunt for “cute stuff that isn’t too expensive.”By her own admission, green just isn’t yet on her mind. But –thanks to the combined efforts of designers, retailers and suppliers –one day it will be.57. What is said about Future Fashion?A) It inspired many leading designers to start going green.B) It showed that designers using organic fabrics would go far.C) It served as an example of how fashion shows should be organized.D) It convinced the public that fashionable clothes should be made durable.58. According to Scott Hahn, one big challenge to designers who will go organicis that .A) much more time is needed to finish a dress using sustainable materials .B) they have to create new brands for clothes made of organic materials .C) customers have difficulty telling organic from non-organic materials .D) quality organic replacements for synthetics are not readily available .59. We learn from Paragraph 3 that designers who undertake greenfashion .A) can attend various trade shows free .B) are readily recognized by the fashion worldC) can buy organic cotton at favorable prices .D) are gaining more and more support .60. What is Natalie Hormilla’s attitude toward ecofashion?A) She doesn’t seem to care about it. C) She is doubtful of its practicalvalue.B) She doesn’t think it is sustainable D) She is very much opposed to theidea61. What does the author think of green fashion?A) Green products will soon go mainstream.B) It has a very promising future.C) Consumers have the final say.D) It will appeal more to young people.Passage TwoQuestions 62 to 66 are based on the following passage.Scientists have devised a way to determine roughly where a person has lived using a strand(缕) of hair , a technique that could help track the movements of criminal suspects or unidentified murder victims .The method relies on measuring how chemical variations in drinking water show up in people’s hair.“You’re what you eat and drink, and that’s recorded in you hair,”said Thure Cerling, a geologist at the University of Utah.While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as raid clouds move.Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid falls first .As a result, storms that form over the Pacific deliver heavier water to California than to Utah.Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.Cerling’s team collected tap water samples from 600 cities and constructeda mop of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops.They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.“It’s not good for pinpointing (精确定位),”Cerling said . “It’s good for eliminating many possibilities.”Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months.She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.“It’s still a substantial area,”Park said “But it narrows it way down for me.”62. What is the scientists’new discovery?A) One’s hair growth has to do with the amount of water they drink.B) A person’s hair may reveal where they have lived.C) Hair analysis accurately identifies criminal suspects.D) The chemical composition of hair varies from person to person.63. What does the author mean by “You’re what you eat and drink”(Line 1, Para.3)?A) Food and drink affect one’s personality development.B) Food and drink preferences vary with individuals.C) Food and drink leave traces in one’s body tissues.D) Food and drink are indispensable to one’s existence.64. What is said about the rainfall in America’s West?A) There is much more rainfall in California than in Utah.B) The water it delivers becomes lighter when it moves inland.C) Its chemical composition is less stable than in other areas.D) It gathers more light isotopes as it moves eastward.65. What did Cerling’s team produce in their research?A) A map showing the regional differences of tap water.B) A collection of hair samples from various barber shops.C) A method to measure the amount of water in human hair.D) A chart illustrating the movement of the rain system.66. What is the practical value of Cerling’s research?A) It helps analyze the quality of water in different regions.B) It helps the police determine where a crime is committed.C) It helps the police narrow down possibilities in detective work.D) It helps identify the drinking habits of the person under investigation.4.Throughout this long, tense election, everyone has focused on the presidential candidates and how they’ll change America. Rightly so, but selfishly, I’m more fascinated by Michelle Obama and what she might be able to do, not just for this country, but for me as an African-American woman. As the potential First Lady, she would have the world’s attention. And that means that for the first time people will have a chance to get up close and personal with the type of African-American woman they so rarely see.Usually, the lives of black women go largely unexamined. The prevailing theory seems to be that we’re all hot-tempered single mothers who can’t keep a man. Even in the world of make-believe, black women still can’t escape the stereotype of being eye-rolling, oversexed females raised by our never-married, alcoholic (酗酒的) mothers.These images have helped define the way all women are viewed, including Michelle Obama. Before she ever gets the chance to commit to a cause, charity or foundation as First Lady, her most urgent and perhaps most complicated dutymay be simple to be herself.It won’t be easy. Because few mainstream publications have done in-depth features on regular African-American women, little is known about who we are, what we think and what we face on a regular basis. For better or worse, Michelle will represent us all.Just as she will have her critics, she will also have millions of fans who usually have little interest in the First Lady. Many African-American blogs have written about what they’d like to see Michelle bring to the White House—mainly showing the world that a black woman can support her man and raise a strong black family. Michelle will have to work to please everyone—an impossible task. But for many African-American women like me, just a little of her poise (沉着), confidence and intelligence will go a long way in changing an image that’s been around for far too long.57. Why does Michelle Obama hold a strong fascination for the author?A) She serves as a role model for African women.B) She possesses many admirable qualities becoming a First Lady.C) She will present to the world a new image of African-American women.D) She will pay closer attention to the interests of African-American women.58. What is the common stereotype of African-American women according to the author?A) They are victims of violence. B) They are of an inferior violence.C) They use quite a lot of body language. D) They live on charity and socialwelfare.59. What do many African-Americans write about in their blogs?A) Whether Michelle can live up to the high expectations of her fans.B) How Michelle should behave as a public figure.C) How proud they are to have a black woman in the White House.D) What Michelle should do as wife and mother in the White House.60. What does the author say about Michelle Obama as a First Lady?A) However many fans she has, she should remain modest,B) She shouldn’t disappoint the African-American community.C) However hard she tries, she can’t expect to please everybody.D) She will give priority to African-American women’s concerns.61. What do many African-American women hope Michelle Obama will do?A) Help change the prevailing view about black women.B) Help her husband in the task of changing America.C) Outshine previous First Lady.D) Fully display her fine qualities.Passage TwoQuestions 62 to 66 are based on the following passage.When next year’s crop of high-school graduates arrive at Oxford University in the fall of 2009, they’ll be joined by a new face; Andrew Hamilton, the 55-year-old provost (教务长) of Yale, who’ll become Oxford’s vice-chancellor—a position equivalent to university president in America.Hamilton isn’t the only educator crossing the Atlantic. Schools in France, Egypt, Singapore, etc, have also recently made top-level hires from abroad. Higher education has become a big and competitive business nowadays, and like so many businesses, it’s gone global. Yet the talent flow isn’t universal. High-level personnel tend to head in only one direction: outward from America.The chief reason is that American schools don’t tend to seriously consider looking abroad. For example, when the board of the University of Colorado searched for a new president, it wanted a leader familiar with the state government, a major source of the university’s budget. “We didn’t do any global consideration,”says Patricia Hayes, the board’s chair. The board ultimately picked Bruce Benson, a 69-year-old Colorado businessman and political activist (活动家) who is likely to do well in the main task of modern university presidents: fund-raising. Fund-raising is a distinctively American thing, since U.S. schools rely heavily on donations. The fund-raising ability is largely a product of experience and necessity.Many European universities, meanwhile, are still mostly dependent on government funding. But government support has failed to keep pace with rising student number. The decline in government support has made funding-raising an increasing necessary ability among administrators and has hiring committees hungry for Americans.In the past few years, prominent schools around the world have joined the trend. In 2003, when Cambridge University appointed Alison Richard, anotherformer Yale provost, as its vice-chancellor, the university publicly stressed that in her previous job she had overseen “a major strengthening of Yale’s financial position.”Of course, fund-raising isn’t the only skill outsiders offer. The globalization of education means more universities will be seeking heads with international experience of some kind of promote international programs and attract a global student body. Foreigners can offer a fresh perspective on established practices.62. What is the current trend in higher education discussed in the passage?A) Institutions worldwide are hiring administrators from the U.S.B) A lot of political activists are being recruited as administrators.C) American universities are enrolling more international students.D) University presidents are paying more attention to funding-raising.63. What is the chief consideration of American universities when hiring top-level administrators?A) The political correctness. B) Their ability to raise funds.C) Their fame in academic circles. D) Their administrative experience.64. What do we learn about European universities from the passage?A) The tuitions they charge have been rising considerably.B) Their operation is under strict government supervision.C) They are strengthening their position by globalization.D) Most of their revenues come from the government.65.

大学英语四级阅读理解习题及答案高校英语四级阅读理解习题及答案引导语：英语六级阅读理解难度不一般，以下是我整理的高校英语四级阅读理解习题及答案，欢迎参考!Questions 21 to 25 are based on the following passage:It is simple enough to say that since books have classes fiction, biography, poetrywe should separate them and take from each what it is right that each should give us. Yet few people ask from books what books can give us. Most commonly we come to books with blurred and divided minds, asking of fiction that it shall be true, of poetry that it shall be false, of biography that it shall be flattering, of history that it shall enforce our own prejudices. If we could banish all such preconception when we read, that would be an admirable beginning. Do not dictate to your author; try to become him. Be his fellow worker and accomplice(同谋). If you hang back, and reserve and criticize at first, you are preventing yourself from getting the fullest possible value from what you read. But if you open your mind as widely as possible, then signs and hints of almost imperceptible finess(委婉之处), from the twist and turn of the first sentences, will bring you into the presence of a human being unlike any other. Steep yourself in this, acquaint yourself with this, and soon you will find that your author is giving you, or attempting to give you, something far more definite. The thirty two chapters of anovelif we consider how to read a novel firstare an attempt to make something as formedand controlled as a building but words are more impalpable than bricks, reading is a longer and more complicated process than seeing. Perhaps the quickest way to understand the elements of what a novelist is doing is not to read, but to write; to make your own experiment with the dangers and difficulties of words. Recall, then, some event that has left a distinct impression on youhow at the corner of the street, perhaps, you passed two people talking. A tree shook; an electric light danced; the tone of the talk was comic, but also tragic; a whole vision, an entire conception, seemed contained in that moment.21.What does the author mean by saying "Yet few people ask from books what books can give us.'?A.The author means that lots of people read few books.B.The author thinks that readers have only absorbed part of knowledge in books.C.The author holds that few people have a proper idea about what content some kind of books should include.D.The author considers that readers can scarcely understand most of the books.22.According to the passage, which of the following statement is right?A.A reader should find some mistakes when he is reading.B.The more difficult a book is, the more you can get fromit.C.To read something is easier than to watch something.D.One should be in the same track with the writer when he is reading.23.What is the possible meaning of "impalpable' (Paragraph 2) in the passage?A.Clear.B.Elusive.C.Delicate.D.Precise.24.Whats the main idea of this passage?A.The importance of reading.B.The proper way to read.C.How to get most from one book.D.The characters of a good book.25.When a writer is writing he often get the whole conception ____.A.after a long times thinkingB.through an instant inspirationC.according to his own experienceD.by way of watching the objects attentively参考答案：21.答案C。

以下是店铺为大家搜索整理的大学CET4考试阅读练习及答案，希望能个大家带来帮助!The motor vehicle has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows essentially from uncivil behavior of drivers who refuse to respect the legal and moral rights of others. So the massacre on the road may be regarded as a social problem.In fact, the enemies of society on wheels are rather harmless people or ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of the killers go even beyond carelessness to total negligence.Researchers have estimated that as many as 80 per cent of all automobile accidents can be attributed to the psychological condition of the driver. Emotional upsets can distort drivers' reactions, slow their judgment, and blind them to dangers that might otherwise be evident. The experts warn that it is vital for every driver to make a conscious effort to keep one's emotions under control.Yet the irresponsibility that accounts for much of the problem is not confined to drivers. Street walkers regularly violate traffic regulations; they are at fault in most vehicle walker accidents. And many cyclists even believe that they are not subject to the basic rules of the road.Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicle havebeen raised both at the point of manufacture and through periodic road-worthiness inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to convince people that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things pose a threat to those with whom they share the road.62. The word “massacre” in line 3 paragraph one means _____A) mass-killing.B) disaster.C) tragedy.D) accident.63. What is the author's main purpose in writing the passage?A) T o show that the motor vehicle is a very dangerous invention.B) To promote understanding between careless drivers and street walkers.C) To discuss traffic problems and propose possible solutions.D) To warn drivers of the importance of safe driving.64. According to the passage, traffic accidents may be regarded as a social problem because _____.A) autos have become most destructive to mankindB) people usually pay little attention to law and moralityC) civilization brings much harm to peopleD) the lack of virtue is becoming more severe65. Why does the author mention the psychological condition of the driver in Paragraph Three?A) To give an example of the various reasons for road accidents.B) To show how important it is for drivers to be emotionally healthy.C) To show some of the inaccurate estimations by researchers.D) To illustrate the hidden tensions in the course of driving.66. Who are NOT mentioned as being responsible for the road accidents?A) Careless bicycle-riders.B) Mindless people walking in the street.C) Irresponsible drivers.D) Irresponsible manufactures of automobiles.答案解析:62-66：ACBBD。

英语四级阅读真题与答案每门学科都有其特点，英语四级的阅读理解，需要多背多记多练，下面是我给大家整理的一些学习资料，盼望对大家有所关心。

6月英语四级阅读真题及答案：长篇阅读段落匹配Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Resilience Is About How You Recharge, Not How You Endure[A] As constant travelers and parents of a 2-year-old, we sometimes fantasize about how much work we can do when one of us gets on a plane, undistracted by phones, friends, or movies. We race to get all our ground work done: packing, going through security, doing a last-minute work call, calling each other, then boarding the plane. Then, when we try to have that amazing work session in flight, we get nothing done. Even worse, after refreshing our email or reading the same studies over and over, we are too exhausted when we land to soldier on with (连续处理) the emails that have inevitably still piled up.[B] Why should flying deplete us? We’re just sitting there doing nothing. Why can’t we be tougher, more resilient (有复原力的) and determined in our work so we can accomplish all of the goals we set for ourselves? Based on our current research, we have come to realize that the problem is not our hectic schedule or the plane travel itself; the problem comes from a misconception of what it means to be resilient, and the resulting impact of overworking.[C] We often take a m ilitaristic, “tough” approach to resilience and determination like a Marine pulling himself through the mud, a boxer going one more round, or a football player picking himself up off the ground for one more play. We believe that the longer we tough it out, the tougher we are, and therefore the more successful we will be. However, this entire conception is scientifically inaccurate.[D] The very lack of a recovery period is dramatically holding back our collective ability to be resilient and successful. Research has found that there is a direct correlation between lack of recovery and increased incidence of health and safety problems. And lack of recovery—whether by disrupting sleep with thoughts of work or having continuous cognitive arousal by watching our phones—is costing our companies $62 billion a year in lost productivity.[E] And just because work stops, it doesn’t mean we are recovering.We “stop” work sometimes at 5pm, but then we spend the night wrestling with solutions to work problems, talking about our work over dinner, and falling asleep thinking about how much work we’ll do tomorrow. In a study just released, researchers from Norway found that 7.8% of Norwegians have become workaholics(工作狂). The scientists cite a definition of “workaholism” as “being overly concerned about work, driven by an uncontrollable work motivation, and investing so much time and effort in work that it impairs other important life areas.”[F] We believe that the number of people who fit that definition includes the majority of American workers, which prompted us to begin a study of workaholism in the U.S. Our study will use a large corporate dataset from a major medical company to examine how technology extends our working hours and thus interferes with necessary cognitive recovery, resulting in huge health care costs and turnover costs for employers.[G] The misconception of resilience is often bred from an early age. Parents trying to teach their children resilience might celebrate a high school student staying up until 3am to finish a science fair project. What a distortion of resilience! A resilient child is a well-rested one. When an exhausted student goes to school, he risks hurting everyone on the road with his impaired driving;he doesn’t have the cognitiv e resources to do well on his English test; he has lower self-control with his friends; and at home, he is moody with his parents. Overwork and exhaustion are the opposite of resilience and the bad habits we acquire when we’re young only magnify when we hit the workforce.[H] As Jim Loehr and Tony Schwartz have written, if you have too much time in the performance zone, you need more time in the recovery zone, otherwise you risk burnout. Gathering your resources to “try hard” requires burning energy in o rder to overcome your currently low arousal level. It also worsens exhaustion. Thus the more imbalanced we become due to overworking, the more value there is in activities that allow us to return to a state of balance. The value of a recovery period rises in proportion to the amount of work required of us.[I] So how do we recover and build resilience? Most people assume that if you stop doing a task like answering emails or writing a paper, your brain will naturally recover, so that when you start again later in the day or the next morning, you’ll have your energy back. But surely everyone reading this has had times when you lie in bed for hours, unable to fall asleep because your brain is thinking about work. If you lie in bed for eight hours, you may have rested, but you can still feel exhausted the next day. That’sbecause rest and recovery are not the same thing.[J] If you’re trying to build resilience at work, you need adequate internal and external recovery periods. As researchers Zijlstra, Crop ley and Rydstedt write in their 2021 paper: “Internal recovery refers to the shorter periods of relaxation that take place within the frames of the work day or the work setting in the form of short scheduled or unscheduled breaks, by shifting attention or changing to other work tasks when the mental or physical resources required for the initial task are temporarily depleted or exhausted. External recovery refers to actions that take place outside of work—e.g. in the free time between the work days, and during weekends, holidays or vacations.” If after work you lie around on your bed and get irritated by political commentary on your phone or get stressed thinking about decisions about how to renovate your home, your brain has not received a break from high mental arousal states. Our brains need a rest as much as our bodies do.[K] If you really want to build resilience, you can start by strategically stopping. Give yourself the resources to be tough by creating internal and external recovery periods. Amy Blankson describes how to strategically stop during the day by using technology to control overworking. She suggests downloading the Instant or Moment apps to see how many times you turn on your phoneeach day. You can also use apps like Offtime or Unplugged to create tech free zones by strategically scheduling automatic airplane modes. The average person turns on their phone 150 times every day. If every distraction took only 1 minute, that would account for 2.5 hours a day.[L] In addition, you can take a cognitive break every 90 minutes to charge your batteries. Try to not have lunch at your desk, but instead spend time outside or with your friends—not talking about work. Take all of your paid time off, which not only gives you recovery periods, but raises your productivity and likelihood of promotion.[M] As for us, we’ve started using our plane time as a work-free zone, and thus time to dip into the recovery phase. The results have been fantastic. We are usually tired already by the time we get on a plane, and the crowded space and unstable internet connection make work more challenging. Now, instead of swimming upstream, we relax, sleep, watch movies, or listen to music. And when we get off the plane, instead of being depleted, we feel recovered and ready to return to the performance zone.36. It has been found that inadequate recovery often leads to poor health and accidents.37. Mental relaxation is much needed, just as physical relaxationis.38. Adequate rest not only helps one recover, but also increases one’s work efficiency.39. The author always has a hectic time before taking a flight.40. Recovery may not take place even if one seems to have stopped working.41. It is advised that technology be used to prevent people from overworking.42. Contrary to popular belief, rest does not equal recovery.43. The author has come to see that his problem results from a misunderstanding of the meaning of resilience.44. People’s distorted view about resilience may have developed from their upbringing.45. People tend to think the more determined they are, the greater their success will be.答案：36.D37. J38. L39. A40.

十六Trees should only be pruned when there is a good andclear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away ofobergrown and unwanted branches, and the inexperiencedgardener can be encouraged by the thought that moredamage results from d oing it unnecessarily than from l eavingthe tree to grow in its own way.First, pruning may be d one to make sure that trees havea desired shape or size. The object may be to get a tree of theright height, and at the same time to help the growth of smallside branches which will thicken its appearance or give it aspecial shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, orbranches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventingthe free movement of air.One result of pruning is that an open wound is l eft onthe tree and this provides an easy entry for disease, but itis a wound that will heal. Often there is a race between thehealing and the d esease as to whether the tree will live or die, so that there is a period when the tree is at risk. It shoul d be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be sl o wed down by roughness. You shoul d allow the cut surface to dry for a few hurs and then paint it with one of the substances availablefrom garden shops produced especially for this purpose. Pruning is usually without interference from the l eaves and also it is very unlikely that the cuts yu make will bl e ed. If thisdoes happen,it is, of course,impossible to paint themproperly.should be done to ______.the tree grow tallerthe shape of the treerid of the small branchesthe small branches thickerbecome unhealthy if the gardener ______.too many branches to grow in the middlenot protect them from windthem to grow too quicklysome of the small side branchesis a special substance painted on the tree?make a wound smoothprevent disease entering a woundcover a rough surfacehelp a wound to drygood gardener prunes a tree______.intervals throughout the yearquickly as possiblewhen necessaryevery winterwas the author's purpose when writingthis passage?give pratical instruction for pruning a tree.give a general description of pruningexplain how trees develop diseasesdiscuss different methods of pruning.答案： babca十七On Thursday afternoon Mrs. Carke, dressed for going out,took her handbag with her money and her key in it, pulled the door behind her to lock it and went to theover 60s Club. She always went there on Thursdays. It was a nice outing for anold woman who lived alone.At six o'clock she cane home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the backdoor and the windows. All were locked or fastened, as usual. There was no signof forced entry.Over a cup of tea she wondered whether someone might have a key that fitted her front door-"a master key"perhaps. So she stayed at home the following Thursday.Nothing happened. Was anyone watching her movements? On the Thursday after that she went out at her usual time,dressed as usual, but she didn't go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.It was just after four o'clock when the front door bell . Clarke was making acup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towardsthe front door. A long piece of wire appeared through the letter-box, and then ahand. The wire turned and caught around the knob on the door-lock.Mrs. Clarke raisedthe kettle and poured the water over the hand. There was a shout outside, and theskin seemed to drop off the fingers like a glove. The wire fell to the floor, thehand was pulled back, and Mrs. Clarke heard the sound of running feet..

Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes,and even snowblindness,when exposed to several hours of "snow light" .The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered , a man's eyes frequently find nothingto foucs on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of tsomethingto look at. Finding nothing, hour after hour, the eyes never sotp searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation byproducing more and fluid which covers the eyeball. The fluid coversthe eyeballin increasing quantity until vision blurs, then is obsured,and the result is total,even though temporary,snowblindness.Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes,creating a dotted line as they cross completely snow-covered landscape,Even thescouts themselves throw lightweight , dark colored objects ahead on which they too can focus . The men following can then see gaze is arrested. Their eyes focus ona bush and having found something to see,stop scouring the snow-blanketed lanscape. By focusing their attention on one object at a time,the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is overcome.prevent headaches, watering eyes and blindness caused by the glare from snow, dark glasses are_____.the eyes are sore tears are produced to ________.the visionsnowblindnessthe irritationthe musclesmay be avoided by_______.to the solid white terrainfor something to look at in snow-covered terrainthe eyes with something to foucs onthe eyeballs with fluidscouts shake snow from evergreen bushes in order to _______.the men behind something to seethe landscapethemselves in the coldthe men behind from losing their waysuitable title for this passage would be _______.and how to overcome it's cure for snowblindnessin the snowvision答案： CCCAA十九Water problems in the future will become nore intense and more complex. Ourincreasing population will tremendously increase urban wastes,primarily sewage. On the other hand, increasing demands for water will decease substantialy the amountof water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidlyexpanding population, agriculture will have to be intensified. This will involveever-increasingquantities of agricultural chemicals, From this , it is apparent that drastic steps must be taken immediately to develop corrective measures forthe pollution problem.There are two ways by which this pollution problem can be dwindled. The firstrelates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to " disposal and the treatment of liquid wastes, or efflunets,to permit the reuse of the water or minimize pollution uponfinal disposal.A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement . Effluents from sewage disposal plants are used in some areas both for irrigation and for thenutrients contained. Efflunets from other processing plants may also be used as asupplemental source of water. Many industries,such as meat and poultry processingplants, are currently converting former waste products into marketable Other industries are potential eonomic uses for waste products.purpose of this passage is ______.alert the reader to the dwindling water supplyexplain industrial uses of wateracquaint the reader with water pollution problemsdemostrate various measures to solve the pollution problemof the following points is NOT INCLUDED in the passage?dustrial development incudes the simplification of complex chemicalwastes needs certain amount of waterfor water will go up along with the expanding populationcultivation of land requires more and more chemicalsreader can conclued that________.of the world will work together on polution problemsfrom wastes lead to a more prosperous marketplaceis making great progress on increasing water suppliesindustries are now ,aking economic use of wastesauthor gives substance to the passage through the use of _______.with authorities in the field of water controlsand personal observationswhich clarify important terms byproducts. processes.arguments and persuasionswords "prior to " probably mean______.答案 :cadbc二十One of the qualities that most people admire in others is the willingness toadmit one's mistakes. It is extremely hard sometimes to say a simple thing like "Iwas wrong about that," and it is even harder to say, "I was wrong , and you wereright about that."I had an experience recently with someone admitting to me that he had made amistake fifteen years ago. He told me he had been the manager of a certain grocerystore in the neighbourhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and Ibegan to remember vaguely the incidenthe was describing.I was about eight years old at the time, and I had gome into the mother to do the weekly grocery shopping.

Why do they do it?There are several answers.The idea of cooperating and sharing responsibility with one another for the benefit of all is as old as the country itself.When the country was first founded in 1776，it was necessary for the settlers to work together to live.They had crossed dangerous seas and risked all they had in their struggle for political and religious freedom.There remains among many Americans a distrust of central government.People still prefer todo things themselves within their munities，rather than give the government more control.Sometimes people offer their time because they wish to plish something for which no money is paid，to do something that will be of benefit to the entire munity.It is true that some people use their leisure because they are truly interested in the work;or they are learning from the experience.No matter what the reason is，hundreds of thousands of so.called leisure hours are put into hard，unpaid work on one or another munity need.59.This passage is mainly about ________ .A.why America is a country of sportsB.how Americans spend their free timeC.why Am erica is a“self-improvement”countryD.how Americans are devoted to their munity activities60.The writer mentions the foundation of the country in order to indicate ________.A.the early history of AmericaB.the American people’s determinat ion to liveC.the reason for Americans’ willingness to cooperate and share responsibilityD.the American people’s love for freedom61.Which of the following best explains the meaning of the underlined word“leisure”?A.work timeB.energyC.effortD.spare time62.What can we infer from the text?A.The first settlers left their hometown for political and religious reasons.B.Many Americans don′t trust the central government.C.American people enjoy building things for their homes just for fun.D.Americans continue their education at their own expense.CWorldwide，almost as many women as men die from heart disease.Yet most treatment methods have e from studies of men.Researchers are now learning more about ways that heart.disease can be different in women.For example，they say a condition called coronary microvascular syndrome(冠脉微血管综合症)appears to be more mon in women than men.When a heart attack is suspected，doctors look for a major blockage(阻塞物)in the arteries(动脉)that supply oxygen to theheart.With coronary microvascular syndrome，fatty material spreads evenly(均匀地)in very small arteries of the heart.This buildup of plaque(血小板)along the artery wall narrows the flow of oxygen.The pain can be similar to that of blocked arteries.But doctors often miss this condition because it does not show up in the usual tests for blockages. Women are often sent home，thinking they are OK.Yet many are at high risk for a heart attack.In USA，researchers say as many as three million women could have coronary microvascular syndrome.The Journal of the American College of Cardiology recently published findings from a government study.The study is called the Women's Ischemia Syndrome Evaluation(妇女缺血综合征的评价)，or WISE.Ischemic heart disease involves restricted blood flow.The study began in nineteen ninety-six and involves more than nine hundred women who suffer chest pain.Researchers found large blockages in major arteries in about one-third of the women.The other women looked clear on an angiogram(血管造影)test for blockages.But the researchers say half of them had enough buildup in small arteries to cause a heartattack within five years.In men and women both，the most mon warning sign is chest pain.But women are more likely to experience other mon signs like shortness of breath，a sick stomach and pain in the back or jaw.A cold sweat and feeling lightheaded can also mean a heart attack.63.Which of the following may be the best title for the text?A.Tests of ten Miss a Hidden Heart-Attack Risk in WomenB.Researchers Find New Ways in Treating Heart DiseasesC.Researchers Find Heart Disease Treatment Methods for WomenD.Women’s Ischemia Syndrome Evaluation Study64.In order to find ways in treating heart disease ________.A.the government has wasted large amount of money in the research workB.researchers used to make studies of both men and womenC.researchers used to make studies of menD.researchers used to make studies of women65.Which of the following is TRUE?A.A lot more men die as a result of heart disease than women do.B.Women are more likely to suffer coronary microvascular syndrome than men.C.Warning signs of heart disease are mon in men and women.D.Heart disease can’t be different in men and women.66.Women’s Ischemia Syndrome Evaluation Study was organized ________.A.by some medical researchersB.by the American governmentC.by the American College of CardiologyD.by the American patients suffering from heart disease67.The most mon sign in women with heart disease is ________ ___A.shortness of breathB.a sick stomachC.pain in the back or jawD.pain in the chest参__56.A 57.C 58.A 59.B 60.C 61.D 62.A 63.A 64.C 65.B66.B 67.D。

四级阅读答案（整理10篇）篇1：四级阅读答案四级阅读答案四级英语考试阅读题：Questions 56 to 60 are based on thefollowing passage.Scientists at Washington University School of Medicine in the US found higher levels of protein S1PR2(磷酸鞘氨醇受体蛋白)in tests on the brains of female mice and dead women with MS than in male equivalents.Four times more women than men are currently diagnosed with Multiple Sclerosis(多发性硬化症).Experts said the finding was”really interesting”.MS affects the nerves in the brain and spinal cord，which causes problems with muscle movement，balance and vision.It is a major cause ofdisability,and affects about 1 00，000 people in the UK.Abnormal immune cells aRack nerve cells in the central Nervous system in MS patients.There is currently no cure，A.though there are treatments that can help in the early stages of the disease.Researchers in Missouri looked at relapsing remitting(复发缓解型)MS，where people have distinct attacks of symptoms that tllen fade away either partially or completely.About 85%of all people with MS have this type.Scientists studied the blood vessels and brains of healthy mice，mice with MS，and mice without the gene for SlPR2，a blood vessel receptor protein，to see how it affected MSseverity.They A.so 100ked at the brain tissue samples of 20 people after they had died.They found high levels of S1PR2 in the areas of the brain typically damaged by MS in both mice and people.Tlle activity of the gene coding for S1 PR2 was positively correlated with the severity of the disease in mice.the study said.Scientists said S l PR2 could work by helping to make the blood-brain barrier,in charge of stopping potentiA.ly harmful substances from entering the brain and spial fluid.more permeable.A more permeable barrier could let attacking cells，which cause MS，into the central nervous system，the study said.This link[between MS and SlPR2] is completely new一it has never been found before.Dr Emma Gray,of the MS Society,said：”We don’t yet fully understand why MS affects more women than men,and it’s an areathat’s intrigued scientists，and people with MS，for many years.She said understanding the causes of MS wa s a“priority”for the MS Society in the UK.and could be“crucial”in finding new treatments.56.What can we infer from the last sentence in Para.1 ?A. Wbmen are more likely to be diagnosed with Multiple Sclerosis.B.Men are more likely to be diagnosed with Multiple Sclerosis.C.Male mice are more likely to be diagnosed with Multiple Sclerosis.D、FemA.e mice are more likely to be diagnosed with Multiple Sclerosis.57.What problem does MS mainly cause?A.In natured muscle movement.B.Bad bA.ance.C. DisabilityD.Bad eyesight.58.What is the relationship between the severity ofMS and level ofSlPR2?A. A.The level of S 1 PR2 is higher,the MS is less severe.B.The level of S 1PR2 is higher,the MS is more severe.C. The level of S 1 PR2 is lower,the MS is less severe.D、The level of S 1 PR2 is lower,the MS is more severe.59.What role does SlPR2 play in helping the permeabilityofblood.brain barrier?A.It can make blood.brain barrier impermeable.B.It can make blood—brain barrier less permeable.C.It can make blood—brain barrier permeable.D.It can make blood—brain barrier more permeable.60.What can we infer from the whole passage?A.Four times more women than men are currently diagnosed with MS.B. The level of S 1 PR2 was positively correlated with theseverity of MS.C.The reason why MS affects more women than men is unknown.D.Multiple sclerosis discovery may explain gender gap.Questions 61 to 65 are based on e web search—-which scours only the latest updates to services like Twitter—is currently generating quite a buzz because it can provide a glimpse of what people around the world are thinking or doing at any given moment.Interest in this kind of search is so great that，according to recent leaks，Google is considering buying Twitter.The latest research from the interact search giant，though，suggests that real—time results could be even more powerful—they may reveal the future as well as the present.Google researchers Hyunyoung Choi and Hal Varian combined data from Google Trends on the popularity of different search terms with models used by economists to predict trends in areas such as travel and home sales.The result?Better forecasts in A.most every case.It works because searches reveal something about people’sintentions.Google has demonstrated before that search data canpredict flu outbreaks，and last week World Bank economist Erik Feyen said he could cut errors in a model that forecasts lending to the private sector by 15%using Google search data.But real-time results could have even more predictive power：knowing what people are actually doing，not just thinking，at a particular instant gives a strong hint of the future consequences. Johan Bollen of Los A.amos NationA. Laboratory and A.berto Pepe of the University of California，Los Angeles，applied a mood rating system to the text from over 10，000 Future Me emails sent in to gauge people’s hopes，fears and predictions for the future.They found that emails directed at to were significantly more depressed in tone than messages aimed at the subsequent six years.Could they have predicted the world’s current economic slump?Without more data，that is no more than an intriguingpossibility.So Bollen plans to look at more Future Me emails，as well as Twitter messages，to search for mood swings that foreshadow other economic changes.If he finds any such links.the sanle sources might be used to try and predict future economic fluctuations.So will our online footsteps become a central part of economic forecasting?We’11 have to wait and see——0r perhaps do a quick web search.61.What is real-time web search.like Twitter?A.It tells us what people did in past days.B.It generates quite a buzz in recent days.C.It provides latest news about everything.D.It informs what people do in the future.62.What is the result of research established by Google researchers Hyunyoung Choi and Hal Varian?A.They gain nothing special from the combination of data and models.B. 11ley indeed reveal something about people’s intentions in such areas.C. They find that the future trends cannot be predicted from the research.D.They totally understand the future trends of these areas from research.63.What can we infer from Para.5?A. It is possible for researchers to get some hints from the Future Me emails.B. There is no relationship between the depression and economic slump.C.There is a potential relationship between depression and economic slump.D.The Future Me emails may indicate people’s reaction about future prediction.64.What’s the meaning of“Without more data,that is no more than an intriguing possibilit y.”?A. More data are necessary to turn this possibility to be reality.B.The possibility is just all intriguing possibility without data.C. No amount of data cannot be a strong proof for thepossibility.D.More data are needed to turn it out to be a pure possibility.65.What’s the attitude of author to real.time search?A.Negative.B.istic.D.Indifferent.：56.What can we infcr from the last sentence in Para.从第一段最后一句话可以推断出什么?A.Women are more likely to be diagnosed with Multiple Sclerosis.女性更容易被诊断出患多发性硬化症。

大学英语四级CET4阅读理解考试题及答案大学英语四级CET4阅读理解考试题及答案英语作为文科科目当中的一个重要组成部分，需要记忆理解的东西比理科要多的多，所以复习的战线需要拉得更长，下面是小编为大家搜索整理的英语四级辅导练习，希望能给大家带来帮助!Japan is getting tough about recycling—and not inthe paper and plastic kind of way. Recently, thecountry requires that all electronic goods—TVs,VCRs, stereos, and more—be recycled. But recyclingwill not beleft to consumers, instead, the devices willbe sent to the original manufacturer for properdisposal.The new law poses a few challenges to manufacturers who are now rushing to set up collectionnetworks and perfecting techniques to disassemble and recycle older products.With an eyetoward the future, they are also integrating easily recycled materials into new products.Plastics, a major component of most electronicproducts,pose a particular obstacle becausetheir quality becomes worse and worse with age,losing strengthand flexibility even ifreprocessed.NEC Corp. overcomes this problem by creating a plastics sandwich, in which thefilling is 100 percent recycled plastic and the outer layers a mixture of 14 percent recycledmaterial.The resulting plastic has sufficient strength and toughness for use as a case fordesktop PCs. The company, in cooperation with plastic maker Sumitomo Dow, has alsodeveloped a new plastic, which engineers claim retains its mechanical properties throughrepeated recycling. NEC uses the plastic, which is also flame-retardant (阻燃的) in batterycases for notebook PCs.Meanwhile, Matsushita Electric, maker of the Panasonic brand, is avoiding plastic in favor ofmagnesium (镁). Magnesium,says the company, is ideal for re cycling because it retains itsoriginal strength throughrepeated reprocessing. Matsushita has developed moldingtechniques to form magnesium into the case for a 21-inch TV. Unfortunately, the magnesiumcase and energy-saving features make the TV about twice as expensive as an ordinarymodel.The company hopes, however, that increased use of magnesium will eventually bringprices down.练习题：Choose correct answers to the question:1. According to the present regulations of Japan, the recycling of paper and plasticwill be the responsibility of______.A.. the governmentB. the manufacturersC. the consumersD. the sellers2. Which of the following is NOT the character of plastics?A. Most electronic products contain plastics.B. It retains its original strength through reprocessing.C.
