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CET4阅读练习题及答案英语四级CET4精选阅读练习题及答案在当今这个学习英语风潮盛行的社会，英语似乎已经成为了我们生活中不可或缺的一部分，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!Henry III didn't know much about biology. He went through six wives back in the 1500s, looking for one whocould bear him a son. Scientists now know that it's the father's sperm, not the mother's egg, which determines whether a baby is a boy or a girl. And last week researchers at the Genetics and IVF Institute, a private fertility(生育能力)center in Virginia, announced a new technique that will allow parents to choose the sex of their baby-to-be, before it has even been conceived. The scientist used a tiny laser detector to measure the DNA in millions of sperm cells as they pass single file through a narrow tube, like cattle being herded through a corral(牲口栏). In a study published last week, "girl sperm," which has more DNA—the genetic material—in each cell, was collected, while "boy sperm" was discarded. And when purified girl sperm was used to impregnate(使受孕)a group of mothers, 15 of 17 resulting babies turned out to be girls.The researchers say that "sex selection" can also double a mother's chance of having a son and can be usedto avoid genetic diseases that affect only one gender, such as hemophilia(血友病). But some experts, like New York University fertility specialist Dr. Jamie Grifo, worry that sex selection could lead to a kind ofin uteri(子宫)discrimination, especially in cultures where sons are considered superior to daughters. "It's valuing one gender' over another," Grifo says. "I don't think that's something we should be doing." So far, patients at the institute have been asking for bothboys and girls, in order to "balance" their families. And some ethics experts say that's fine, as long as parents are just looking for a little gender variety. "If you have three boys, and you want a girl," says University of Texas reproductive-law professor John Robertson, "that's not gender bias at all."练习题：Choose correct answers to the question:1.The DNA in the sperm cells can be measured ______.A.in the same way how the cattle are herdedB.when they pass through a tube one behind the otherC.after they pass through a laser tubeD.when they are scanned by a laser detector all at a time2.The gender of the baby is decided by ______.A.the father's DNAB.the mother's DNAC.the father's spermD.the mother's egg3.According to this passage, the practice of "sex selection" ______.A.can help to prevent all genetic problemsB.is totally unacceptable to ethics expertsC.was already realized five hundred years agoD.will benefit families with certain inheritable diseases4.Girl sperm was preferred to boy sperm in the research most probably because____A.girl sperm contains more genetic materialB.more mother want to have girl babiesC.girl sperm is healthier and more activeD.girl sperm is more easily purified5.It can be concluded from the passage that author’stoward”sex selection”is____A.negativeB.positiveC.neutralD.favorable参考答案1.[B] 推理判断题。

They have opened the eyes of students in underdeveloped regions to the outside world by bringing them new knowledge and thoughts. As a result, they are extremely well—received by the children there. On the other hand, college students have received a rigorous training by adapting to the harsh living conditions. They are enjoying the appreciation and no—distance friendship from the children.

Why does this craze appear?There are mainly two reasons behind this phenomenon. First, it is the employment pressure that forces college students to get more certificates. With the admission expansion of colleges, a lot more graduates have to face the fierce competition in the job market. How can one makehimself more competitive? More certificates at hand, maybe. Second, diploma and certificates are still important standards by which many employers measure a person’s ability. In order to increase the qualifications for a job, the students compel themselves to run from one exam to another。

Passage OneQuestions 21 to 25 are based on the following passage:The view over a valley of a tiny village with thatched（草盖的）roof cottages around a church; a drive through a narrow village street lines with thatched cottages painted pink or white; the sight in parts of England. Most people will agree that the thatched roof is an essential part of the attraction of the English countryside.Thatching is in fact the oldest of all the building crafts practiced in the British Isles（英论诸岛）. Although thatch has always been used for cottage and farm buildings, it was once used for castles and churches, too.Thatching is a solitary（独自的）craft, which often runs in families. The craft of thatching as it is practiced toady has changed very little since the Middle Ages. Over 800 full-time thatchers are employed in England and Wales today, maintaining and renewing the old roofs as well as thatching newer houses. Many property owners choose thatch not only for its beauty but because they know it will keep them cool in summer and warm in winter.In fact, if we look at developing countries, over half the world lives under thatch, but they all do it in different ways. People in developing countries are often reluctant to go back to traditional materials and would prefer modern buildings. However, they may lack the money to allow them to import the necessary materials. Their temporary mud huts with thatched roofs of wild grasses often only last six months. Thatch which has been done the British way lasts from twenty to sixty years, and is an effective defiance against the heat.C21.Which of the following remains a unique feature of the English countryside?A) Narrow streets lined with pink or white houses.B) Rolling hills with pretty farm buildings.C) Cottages with thatched roofs.D) churches with cottages around them.D22.What do we know about thatching as a craft?A) It is a collective activity.B) It is practised on farms all over England.C) It is quite different from what it used to be.D) It is in most cases handed down among family members.A23.Thatched houses are still preferred because of _________.A) their style and comfortB) their durabilityC) their easy maintenanceD) their cheap and ready-made materialsB24.People in developing countries also live under thatch because ________.A) thatched cottages are a big tourist attractionB) thatched roof houses are the cheapestC) thatch is an effective defense against the heatD) they like thatched houses better than other buildingsA25.We can learn from the passage that _________.A) thatched cottages in England have been passed down from ancient timesB) thatching is a building craft first created by the English peopleC) the English people have a special liking for thatched housesD) most thatched cottages in England are located on hillsides答案：CDABAPassage TwoQuestions 26 to 30 are based on the following passage:President Coolidge’s statement, “The business of America is business,”still points to an important truth today-that business institutions have more prestige（威望）in American society than any other kind of organization, including the government. Why do business institutions posses this great prestige?One reason is that Americans view business as being more firmly based on the ideal of competition than other institutions in society. Since competition is seen as the major source of progress and prosperity by most Americans, competitive business institutions are respected. Competition is not only good in itself, it is the means by which other basic American values such as individual freedom, equality of opportunity, and hard work are protected.Competition protects the freedom of the individual by ensuring that there is no monopoly（垄断）of power. In contrast to one, all-powerful government, many businesses compete against each other for profits. Theoretically, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly. Where many business es compete for the customers’ dollar, they cannot afford to treat them like inferiors or slaves.A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it is more supportive of freedom than government, even though government leaders are elected by the people and business leaders are not. Many Americans believe, then, that competition is as important, or even more important, that democracy in preserving freedom.Competition in business is also believed to strengthen the ideal of equality of opportunity. Competition is seen as an open and fair race where success goes to the swiftest person regardless of his or her social class background. Competitive success is commonly seen as the American alternative to social rank based on family background. Business is therefore viewed as an expression of the idea of equality of opportunity rather than the aristocratic（贵族的）idea of inherited privilege.26.The stat ement “The business of America is business” probably means “________”.A) The business institutions in America are concerned with commerceB) Business problems are of great importance to the American governmentC) Business is of primary concern to AmericansD) America is a great power in world business27.Americans believe that they can realize their personal values only ________.A) when given equality of opportunityB) through doing businessC) by protecting their individual freedomD) by way of competition28.Who can benefit from business competition?A) Honest businessmen.B) Both businessmen and their customers.C) People with ideals of equality and freedom.D) Both business institutions and government.ernment is believed to differ strikingly from business in that government is characterized by ________.A) its absolute control of powerB) its function in preserving personal freedomC) its role in protecting basic American valuesD) its democratic way of exercising leadership30.It can be inferred from the passage that the author believes _________.A) Americans are more ambitious than people in other countriesB) in many countries success often depends on one’s social statusC) American businesses are more democratic than those in other countriesD) businesses in other countries are not as competitive as those in America翻译：柯立芝总统说，“美国的事业就是工商业”，今天这句话仍然指出了一个很重要的真理：工商业机构在美国社会比任何其他组织，包括美国政府，威望更高。

英语四级阅读理解强化练习附答案
英语四级阅读理解强化练习附答案英语四级阅读理解强化练习1：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 forfuture 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.

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 country. Rather, a mans eyes frequently find nothing to focus 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 something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation byproducing more and more fluid which covers the eyeballs. The fluid covers the eyeball in increasing quantity until vision blurs, then is obscured, and the result is total, even though temporary, snowblindness.Experiments led to 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 the snow-blanketed landscape. 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.26. To prevent headache, watering eyes and blindness caused by the glare from snow, dark glasses are _____.A) indispensableB) usefulC) ineffectiveD) available27. When the eyes are sore tears are produced to _____.A) clear the visionB) remedy snowblindnessC) ease the irritationD) loosen the muscles28. Snowblindness may be avoided by _____.A) concentrating on the solid white terrainB) searching for something to look at in snow-covered terrainC) providing the eyes with something to focus onD) covering the eyeballs with fluid29. The eyeballs become sore and the eye muscles ache because _____.A) tears cover the eyeballsB) the eyes are irritated by blinding sunlightC) the eyes are irritated by blinding snowD) there is nothing to focus on30. A suitable title for the passage would be _____.A) Snowblindness and How to Overcome ItB) Natures Cure for SnowblindnessC) Soldiers in the SnowD) Snow Vision英语四级阅读理解强化练习答案：CCCDA。

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。

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。

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. Recycled plastics can be integrated into new products.D. Plastics will lose flexibility after a certain period of time.3.According to the passage, the term “plastic sandwich” refers to_____.A. a kind of sandwich-shaped toy made of plasticsB. a kind of plastics with different integration in each layerC. a kind of plastics with maximum strength and flexibilityD. a kind of plastics made of 100% recycled materials4.In the passage, it is implied but NOT stated that_____.A. disposing the plastics is one of NEC Corp’s businessesB. magnesium is an ideal material for the case of TVC.21-inch TV with magnesium case isn’t very popular so farD. magnesium must be better than the plastics5.The author writes this passage in order to_____.A. informB. instructC. predictD. persuade参考答案1.[C] 推理判断题。

大学英语四级阅读理解试题及答案（四）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 a wound 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 theleaves 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 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 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 and poured 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 againb.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 key/doc/cb303c86bceb19e8b8f6bae3.html eda 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 causes snowblindnenss. 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.

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 expandingindustries 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 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 marketable byproducts. 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 thepassage?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 thewillingness to admit 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 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 knees inspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the culprit.

1. “Feedback mechanisms” in paragraph 1 most probably refer to ________. A. how plants and animals adapt to hidden factors B. how plants and animals interact with the changing climate C. how climate changes D. how climate zones shift
5. Which of the following is the main topic of the passage? A. Material progress and energy consumption. B. Prosperity and cheap fossil fuels. C. Impact of global warming on climate. D. Plants and animals in the changing climate.
2. James Hansen predicts that the shift of climate zones will be accompanied by ________. A. the cutting of many trees. B. desirable environmental changes. C. successful migration of species. D. unsuccessful migration of trees.
Others, like the ‘albedo’ effect, will do the opposite. The ‘albedo’ effect is the amount of solar enee. As northern ice and snow melts and the darker sea and land pokes through, more heat will be absorbed, adding to the global temperature increase.

（Para 1) There are hidden factors which scientists call “feedback mechanisms”. No one knows quite how they will interact with the changing climate. Here's one example: plants and animals adapt to climate change over centuries. At the current estimate of half a degree centigrade of warming per decade, vegetation(植物) may not keep vegetation(植物 植物) up.
Climatologist James Hansen predicts climate zones will shift toward the poles by 50 to 75kilometres a year- faster than trees yearcan naturally migrate. Species that find themselves in an unfamiliar environment will die. The 1000 kilometre-wide strip of forest kilometrerunning through Canada, the USSR and Scandinavia could be cut by half. Millions of dying trees would soon lead to massive forest fires, releasing ions of CO2 and further boosting global warming.
4. It can be inferred from the passage that ________. A. the developing world has decided to increase its energy consumption B. a third-world citizen adds less than a ton thirdof CO2 yearly to the atmosphere C. the world climate would soon gain its balance if we stopped greenhouse gas emissions D. future prosperity of the world is dependent on cheap fossil fuels
3. We can learn from the passage that ________. A. some feedback mechanisms may slow down global warming B. the basic facts of global warming are unknown C. developing countries benefit from cheap fossil fuels D. developed countries have decided to reduce their energy consumption
(Para 2) There are dozens of other possible “feedback mechanisms”. Higher temperatures will fuel condensation and increase cloudiness, which may actually damp down global warming.

(Para 4) Material progress has been linked to energy consumption. Today 75 per cent of all the world's energy is consumed by a quarter of the world's population. The average rich world resident adds about 3.2 tons of CO2 yearly to the atmosphere, more than four times the level added by each Third World citizen. The US, with just seven per cent of the global population, is responsible for 22 per cent of global warming.
