2019英语四级阅读理解练习题（6）As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. Infact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers backto_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbc。

As the name suggests, it blends biology and modern technology through such techniques as genetic engineering. Some of the new biotech companies, as they are called, specialize in agriculture and are working enthusiastically to patent seeds that give a high yield, that resist disease, drought, and frost, and that reduce the need for hazardous chemicals. If such goals could be achieved, it would be most beneficial. But some have raised concerns about genetically engineered crops. "In nature, genetic diversity is created within certain limits," says the book Genetic Engineering, Food, and Our Environment. "A rose can be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering, on the other hand, usually involves taking genes from one species and inserting them into another in an attempt to transfer a desired property or character. This could mean, for example, selecting a gene which leads to the production of a chemical with antifreeze properties from an arctic fish, and joining it into apotato or strawberry to make it frost-resistant. It is now possible for plants to be engineered with genes taken from bacteria, viruses, insects, animals or even humans." In essence, then, biotechnology allows humans to break the genetic walls that separate species.Like the green revolution, what some call the gene revolution contributes to the problem of genetic uniformity--some say even more so because geneticists can employ techniques such as cloning and tissue culture, processes that produce perfectly identical copies, or clones. Concerns about the erosion of biodiversity, therefore, remain. Genetically altered plants, however, raise new issues, such as the effects that they may have on us and the environment. “We are flying blindly into a new era of agricultural biotechnology with high hopes, few constraints, and little idea of the potential outcomes," said science writer Jeremy Rifkin.51. According to the author, biotech companies are _____________.A. mostly specialized in agricultureB. those producing seeds of better propertiesC. mainly concerned about the genetically engineered cropsD. likely to have big returns in their business52. Now biotech products are made _______.A. within the limits of natural geneticsB. by violating laws of natural geneticsC. without the interference of humansD. safer than those without the use of biotechnology53. In nature, genetic diversity is created __________.A. by mixing different speciesB. within the species itselfC. through natural selectionD. through selection or contest54. Biotechnology has made it possible ___________.A. for us to solve the food shortage problem in the worldB. for plants to be produced with genes of humansC. for humans to assume the cold-resistant propertyD. to grow crops with the taste of farm animals55. According to the author, with the development of biotechnology ________.A. the species of creatures will be reducedB. our living environment will be better than it is nowC. humans will pay for its side effectD. we will suffer from fewer and fewer diseases56. The author's attitude towards genetic engineering can best be described as _________.A. optimisticB. pessimisticC. concernedD. suspiciousPassage TwoThe practice of capital punishment is as old as government itself. For most of history, it has not been considered controversial. Since ancient times most governments have punished a wide variety of crimes by death and have conducted executions as a routine part of the administration of criminal law. However, in the mid-18th century, social critics in Europe began to emphasize the worth of the individual and to criticize government practices they considered unjust, including capital punishment. The controversy and debate over whether governments should utilize the death penalty continue today.The first significant movement to abolish the death penalty began during the era known as the Age of Enlightenment. In 1764 Italian jurist and philosopher Cesare Beccaria published An Essay on Crimes and Punishments. Many consider this influential work the leading document in the early campaign against capital punishment. Other individuals who campaigned against executions during this period include French authors Voltaire and Denis Diderot, British philosophers David Hume and Adam Smith, and political theorist Thomas Paine in the United States.Critics of capital punishment argue that it is cruel and inhumane, while supporters consider it a necessary form of revenge for terrible crimes. Those who advocate the death penalty declare that it is a uniquely effective punishment that prevents crime. However, advocates and opponents of the death penalty dispute the proper interpretation of statistical analyses of its preventing effect. Opponents of capital punishment see the death penalty as a human rights issue involving the proper limits of governmental power. In contrast, those who want governments to continue to execute tend to regard capital punishment as an issue of criminal justice policy. Because of these alternative viewpoints, there is a profound difference of opinion not only about what is the right answer on capital punishment, but also about what type of question is being asked when the death penalty becomesa public issue.57. We can learn from the first paragraph that in ancient times ____________.A. death penalty had been carried out before government came into beingB. people thought it was right for the government to conduct executionsC. death penalty was practiced scarcely in European countriesD. many people considered capital punishment unjust and cruel58. Why was capital punishment questioned in the mid-18th century in Europe?A. People began to criticize their government.B. The government was unjust in this period.C. People began to realize the value of life.D. social critics were very active at that time.59. Italian jurist and philosopher Cesare Beccaria _________.A. was the first person to question the rightness of death penaltyB. was regarded as an important author criticizing capital punishmentC. was the first person who emphasized the worth of the individualsD. first raised the theory against capital punishment60. Critics of capital punishment insist that it ________.A. violates human rights regulationsB. is an ineffective punishment of the criminalsC. is just the revenge for terrible crimesD. involves killing without mercy61. The advocates and opponents of the death penalty_________.A. agree that it is a human rights issueB. agree that it can prevent crimesC. explain its statistical analyses differentlyD. think that they are asked different types of questions62. The author's attitude towards capital punishment can be summarized as _________.A. supportiveB. criticalC. neutralD. contradictoryPassage ThreeBears mostly live alone, except for mothers and their babies, and males and females during mating season. Bears form temporary groups only in exceptional circumstances, when food is plentiful in a small area. Recent evidence also suggests that giant pandas may form small social groups, perhaps because bamboo is more concentrated than the patchy food resources of other bear species. Other bears may live alone but exist in a social network. A male and female may live in an area partly shared in common--although they tolerate each other, each defends its range from other bears of the same sex. Male young usually leave their mothers to live in other areas, but female young often live in a range that is commonly shared with that of their mother.The key to a bear's survival is finding enough food to satisfy the energy demands of its large size. Bears travel over huge territories in search of food, and they remember the details of the landscape they cover. They use their excellent memories to return to locations where they have had success finding food in past years or seasons. Most bears are able to climb trees to chase small animals or gain access to additional plant vegetation. The exceptions are polar bears and large adult brown bears--their heavy weight makes it difficult for them to climb trees.Bears that live in regions with cold winters spend the coldest part of the year asleep in sheltered dens, including brown bears, American and Asiatic black bears, and female polar bears. Pregnant females give birth in the winter in the protected surroundings of these dens. After fattening up during the summer and fall when food is abundant, the bears go into this winter home to conserve energy during the part of the year when food is scarce. Winter sleep differs from hibernation in that a bear is easily aroused from sleep. In addition, a bear's body temperature drops only a few degrees in its winter sleep. In contrast, a true hibernator undergoes more extensive changes in bodily functions. For instance, the body temperature of the Arctic ground squirrel drops from 38°C to as low as -3°C.63. Most bears live alone because _______________.A. they don't want to keep a social networkB. each bear feeds on different kinds of foodC. male and female bears can't tolerate each otherD. they don't want other bears to share their food64. According to the passage, bears of the same sex__________.A. can get along with each other peacefullyB. share their range with each otherC. live in an area partly shared in commonD. cannot live peacefully in the same area65. As is told about bears in the passage, we know that___________.A. it is easy for bears to find enough food if they can climb treesB. a bear can long remember where it has found foodC. all except polar bears are able to climb trees to catch their preyD. all except polar bears and adult brown bears feed on small animals66. Bears sleep in their sheltered dens in cold winter because _____________.A. their babies need to be born in a cold and protected surroundingB. they need to fatten themselves up in the cold seasonC. they need to convert their fat into energy in winterD. they cannot find enough food in the cold season67. Winter sleep differs from hibernation in that_______________.A. animals in hibernation don't wake up easilyB. animals in hibernation are aroused regularly for energy supplyC. the body temperature of animals in winter sleep doesn't changeD. animals in winter sleep experience drastic changes in bodily functions68. The passage is mainly about____________.A. the species of bearsB. the food category of bearsC. the winter sleep of bearsD. the behavior of bearsPassage FourThe young man who came to the door--he was about thirty, perhaps, with a handsome, smiling face---didn't seem to find my lateness offensive, and led me into a large room. On one side of the room sat half a dozen women, all in white; they were much occupied with a beautiful baby, who seemed to belong to the youngest of the women. On the other side of the room sat seven or eight men, young, dressed in dark suits, very much at ease, and very imposing. The sunlight came into the room with the peacefulness that one remembers from rooms in one's early childhood—a sunlight encountered later only in one's dreams. I remember being astounded by the quietness, the ease, the peace, and the taste. I was introduced, they greeted me with a genuine cordiality and respect--and the respect increased my fright, for it meant that they expected something of me that I knew in my heart, for their sakes, I could not give--and we sat down. Elijah Muhammad was not in the room. Conversation was slow, but not as stiff as I had feared it would be. They kept it going, for I simply did not know which subjects I could acceptably bring up. They knew more about me and had read more of what I had written, than I had expected, and I wondered what they made of it all, what they took my usefulness to be. The women were carrying on their own conversation, inlow tones; I gathered that they were not expected to take part in male conversations. A few women kept coming in and out of the room, apparently making preparations for dinner. We, the men, did not plunge deeply into any subject, for, clearly, we were all waiting for the appearance of Elijah. Presently, the men, one by one, left the room and returned. Then I was asked if I would like to wash, and I, too, walked down the hall to the bathroom. Shortly after I came back, we stood up, and Elijah entered. I do not know what I had expected to see. I had read some of his speeches, and had heard fragments of others on the radio and on television, so I associated him with strength. But, no---the man who came into the room was small and slender, really very delicately put together, with a thin face, large warm eyes, and a most winning smile. Something came into the room with him--his worshipers' joy at seeing him, his joy at seeing them. It was the kind of encounter one watches with a smile simply because it is so rare that people enjoy one another.69. Which of the following is the best alternative word for "imposing" (line 6)?A. EnthusiasticB. Hostile C, Impressive D. Anxious70. Which word best describes the atmosphere in the room?A. TranquilB. SolemnC. ChaoticD. Stressful71. How did the author feel when he was greeted with respect?A. DelightedB. AstonishedC. EmbarrassedD. Scared72. Which of the following statements is true about the author?A. He talked little.B. He was puzzled.C. He enjoyed the conversation.D. He got more respect than he deserved.73. The men didn't get deeply involved in any subject because they_______.A. had little knowledgeB. didn't know one another wellC. wanted to relax themselvesD. awaited the arrival of someone important74. What can we learn about Elijah?A. He was admired by others.B. He was very handsome.C. He was a man with determination.D. He was happy to give speeches.Passage FiveSingapore's Mixed Reality Lab is working on new ways of interacting with computers, including wearable devices and a virtual war room that will allow officials to work together online as if they were all in one place. Its director is a spiky-haired Australian, a postmodern match for the fictional British agent James Bond's tool man, Q. It is funded by the Defense Science & Technology Agency, which controls half the $5 billion defense budget, and sponsors hundreds of research projects every year. The agency came to worldwide attention last year when it took just one day to customize a thermal scanner in order to detect travelers with high fever, helping to stem the spread of SARS.DSTA is now working on a range of projects that are attracting attention in both the commercial and military worlds. It devised an air-conditioning system that harnesses melting ice and cool seawater to conserve electricity at the new Changi Naval Base, and could have broad civilian applications.Singapore can easily afford Western hardware, but off-the-shelf products are often unsuitable for the tropical conditions in Southeast Asia. For example, the DSTA is funding development of an anti-chemical-weapons suit that works not as a shield, but as a sort of weapon. The Singaporean garments, made of a revolutionary plastic-like materialthat is much lighter and cooler than traditional fabrics, actually degrade suspect substances on contact.Much of the agency's work is geared toward helping this resource-poor city-state overcome its natural limitations, says its director of R&D, William Lau Yue Khei. Conserving manpower is one of the agency's most critical assignments, because Singapore is a nation of 4 million people dwarfed by larger neighbors, includingIndonesia and Malaysia. Right now, the biggest DSTA project is computerizing a stealth warship so that it can run on half the usual crew. Making equipment lighter is a particular agency specialty, because the universal military rule of thumb is that a soldier should carry no more than one third his body weight, and that means that smaller Singaporean soldiers should carry no more than 24 kilos, or 20 percent less than Europeans, says DSTA project manager Choo Hui Weing. One such program: the Advanced Combat Man System, has produced a lightweight handguard that controls an integrated laser range finder, digital compass and a targeting camera. Top that, Q.75. It can be inferred from the passage that Q is probably__________.A. a mechanic in James Bond's garageB. a fictional Australian with spiky hairC. a director of the Advanced Combat Man SystemD. an imaginary engineer who invents advanced equipment76. Which of the following statements concerning DSTA is NOT true?A. It became world-known for its high efficiency in preventing the SARS spread.B. It funds numerous research programs, including Mixed Reality Lab.C. It devised an air-conditioning system now widely used in households.D. It takes credit for conserving electricity at the new Changi Naval Base.77. The suit described in the third paragraph can be used as a sort of weapon mainly because_________.A. it is made of a new material resembling plasticsB. it can reduce harmful effects of chemicals on itC. it has been adapted to the tropical weather thereD. its light weight allows soldiers to carry more equipment78. Which of the following is NOT mentioned as a disadvantage of Singapore?A. Smaller soldiers.B. Smaller population.C. Limited defense budget.D. Limited natural resources.79. The Advance Combat Man System is mentioned in the last paragraph mainly to show_______.A. what DSTA has done to meet the country's special needsB. how sophisticated the equipments designed by DSTA can beC. why it is difficult for Q to compete with Choo Hui WeingD. how Singapore's technology is superior to that of the British80. The main purpose of the passage is to ______________.A. analyze Singapore's defense systemB. summarize the contributions of DSTAC. introduce the technical advantages of a small countryD. describe the roles and achievements of a government agencyPART V TRANSLATION (30 minutes, 20 points)Section A (15 minutes, 10 points)Quitting smoking is more of a matter of willpower than of individual choice, for smoking is widely recognized as addictive. Although counseling and medication can increase the odds that a smoker quits permanently, the best way to avoid dilemmas is never to take up smoking to begin with.The irreversible effects of cigarette smoking vary in intensity and are related both to the amount and duration of exposure and the age at which the person is initially exposed. This report challenges the notion that a few years of exposure to smoking will have no lasting harmful consequences. We hope to discourage this prevalent but vital habit andsuggest that tobacco-related health effects decline substantially as time away from smoking increases.Section B (15 minutes, 10 points)人们越来越意识到开发环保型产品的重要性。

But use of graphene in semiconductors—the technology’s Holy Grail—is likely a decade away.“Many of the challenges presented by graphene are common to most new materials，”Paul Smith,a patent associate with the Intellectual Property Law Group at Fenwick & West，told Fortune.“The trick is figuring out how to synthesize graphene in a way that first is manufacturable beyond lab scale;second，preserves the desirable properties of the material;and third，can be integrated into a product or technology.”graphene in sheet form is considerably more expensive and time-consuming than producing graphene the latter typically involves a“quick and dirty”process by which bulk graphite is disassembled into millions of tiny pieces，Lau explained，large sheets of graphene are carefully“grown”on substrates(基板)such as copper，germanium，or silicon carbide.J. Graphene sheets are also prone to defects and“very difficult to make in good quality,”Ron Mertens，owner and editor of ， capacity is also very limited.“There are thousands of small companies that can make graphene，but it’s expensive and low-capacity,”Mertens wafer measuring one inch in diameter,for instance，costs about$1 00，he added.even thornier obstacle on the way to graphene transistors is the fact that the material has no“band gap，”an essential property that allows transistors to be turned on and off without leaking electronic charge in the“off”state，said Elias Towe，a professor of electrical and computer engineering at Carnegie Mellon University.L.“Band-gap engineering has been and remains the biggest challenge in the development of graphene transistors and computer chips.”Lau requires controlling the material almost down at the atomic level，and“that’s really pushing the edges of existing technology,”Patterson said.“In 10 years，we’11 start to see these problems solved.”‘It is largely a matter of time’graphene is to succeed as a replacement for silicon，every unit of cost and performance will make a difference，Towe said.N.“Silicon is hard to displace，with all the billions dollars of investments made in manufacturing infrastructure，”he said.“A replacement for silicon has to offer extraordinary performance at extremely rock-bottom cost to compel industry to change its way.”graphene is just 10 years old—in contrast,use of silicon in transistors dates to the early 1950s—considerable progress has already been example，the largest graphene sheet was produced by hand in a laboratory eight years ago;its width wasless than that of a human hair.“Nowadays，roll-to-roll printing of graphene sheets up to 1 00 meters long has been achieved，”Lau said.“With the increasing interest，investment，and research in graphene-based technology,I think it is largely a matter of time before the economy of scale kicks in and truly low-cost，large-scale production ofhigh-quality graphene is accomplished，”she added.is the powder-or flake-type of graphene that has been used for some time to make conductors and that is being launched on the market.encourage industry to replace silicon with graphene，it is necessary for graphene to provide high property at an extremely low expense.graphene flakes are roughly processed with bulk graphite，graphene sheets are carefully made on substrates like copper，germanium，or silicon carbide.the past ten has become a hot topic among the scientific and technology groups.won’t come into the market before it can be manufactured at a very low cost.of a much younger age than silicon，great progress has been made in graphene;and with ever increasing interest，investment and research in graphene technology,it’s probable to manufacture cost- effective graphene of high quality.has been attempted to be used for plenty of noticeable applications.it still needs to take ten years for graphene to be used in semiconductors，which lies at the heart of the technology.today’s technology,it is still impossible to control material down at the atomic level.Towe pointed out that having no“band gap”，the dispensable feature of transistors，makes it more difficult to produce graphene transistors.is the powder-or flake-type of graphene that has been used for some time to make conductors and that is being launched on the market.纳米片是粉末状或者薄片状的石墨烯，被用于制作导体已经有一段时间了，而且开始被推向市场。

South Hall, an ivy-covered Gothic-revival building of red brick, is the only survivor of the nineteenth century campus buildings. Today, the Berkeley campus is the senior member of the nine-campus University of California System. Berkeley offers a full range of academic majors in programs. In a national survey published in fall 1992, Berkeley placed highest of all public universities in ranking that included five attributes： reputation, selectivity, faculty resources, financial resources, and student satisfaction. More students who earn bachelor's degrees at Berkeley complete Ph. D's than graduates of any other university in the country.Undergraduate students can choose from more than 5,000 different courses and over 100 majors or they can designtheir own individual majors. The graduate division offers professional and academic degrees in more than 100 majors. Aiding students in their course work is a campus network of twenty-four libraries, including one especially for undergraduates. There are also many support facilities and services available, such as the Student Learning Center,financial aid counseling, housing assistance, graduate and professional school advising, and career placement assistance. The 1, 200-acre campus stretches from downtown Berkeley through wooded hills that overlook San Francisco Bay.

2019年6⽉⼤学英语四级阅读200篇汇总 From the health point of view we are living in a marvelous age. We are immunized from birth against many of the most dangerous diseases. A large number of once fatal illnesses can now be cured by modern drugs and surgery. It is almost certain that one day remedies will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of men, women and children on the roads. Man versus the motor-car! It is a never-ending battle which man is losing. Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen. It has been rightly said that when a man is sitting behind a steering wheel, his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man's very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They swear, they are ill-mannered and aggressive, willful as two-years-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving. The surprising thing is that society smiles so benignly on the motorist and seems to condone his behaviour. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy tragic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten. It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through stringent annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person's driving ability. Present drinking and driving laws (where they exist) should be mad much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately harsh. But surely nothing should be considered as to severe if tit results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars. 1. The main idea of this passage is [A] Traffic accidents are mainly caused by motorists. [B] Thousands of people the world over are killed each year. [C] The laws of some countries about driving are too lax. [D] Only stricter traffic laws can prevent accidents. 2. What does the author think of society toward motorists? [A] Society smiles on the motorists. [B] Huge car parks are built in the cities and towns. [C] Victims of accidents are nothing. [D] Society condones their rude driving. 3. Why does the author say: 'his car becomes the extension of his personality?' [A] Driving can show his real self. [B] Driving can show the other part of his personality. [C] Driving can bring out his character. [D] His car embodies his temper. 4. Which of the followings is NOT mentioned as a way against traffic accidents? [A] Build more highways. [B] Stricter driving tests. [C] Test drivers every three years. [D] raise age limit and lay down safety specifications. 5. The attitude of the author is [A] ironical [B] critical [C] appealing [D] militant 答案： 1. D 只有更严格的交通法规才能制⽌交通事故。

2019年6月英语四级阅读真题及答案：长篇阅读段落匹配
2019年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 (继续处理) 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 militaristic, “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 arerecovering. 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 hurtingeveryone on the road with his impaired driving; he doesn’t have the cognitive 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 order 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’s because 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, Cropley and Rydstedt write in their 2014 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 suggestsdownloading the Instant or Moment apps to see how many times you turn on your phone each 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 relaxation is.38. Adequate rest not only helps one recover, but also increases one’s work efficiency.39. The author always has a hectic time before takinga 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.

2019年6月英语四级模拟预测卷及答案
2019年6月英语四级模拟预测卷及答案2019年6月英语四级模拟预测卷及答案Part II Reading Comprehension (35 minutes)Directions： There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a singleline through the center.Passage OneQuestions 21 to 25 are based on the following passage.There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationshipsbetween observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and proceduresfor implementing the finding of science.Another distinction between science and technology hasto do with the progress in each.Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people's likes or dislikes or to popular ideas about the fitness of things.What scientists discover may shock or anger people-as did Darwin's theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But hardly so with technology; we do not have the choice of refusing to hear the sonic boom produced by a supersonic aircraft flying overhead; we do not have the option of refusing to breathe polluted air; and we do not have the option of living in a non-atomic age. Unlike science progress, technology must be measured in terms of the human factor. The legitimate purpose of technology is to serve people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves. Technology must be humanistic if it is to lead to a better world.21. The difference between science and technology lies in that _____.A) the former provides answers to theoretical questions while the latter to practical problemsB) the former seeks to comprehend the universe while the latter helps change the material worldC) the former aims to discover the inter-connections of facts and the rules that explain them while the latter, to discover new designs and ways of making the things we use in our daily lifeD) all of the above22. Which of the following may be representative of science?A) The improvement of people's life.B) The theory of people's life.C) Farming tools.D) Mass production.23. According to the author, scientific theories _____.A) must be strictly objectiveB) usually take into consideration people's likes and dislikesC) should conform to popular opinionsD) always appear in perfect and finished forms24. The author states that technology itself _____.A) is responsible for widespread pollution and resource exhaustionB) should serve those who wish to gain advantage for themselvesC) will lead to a better world if put to wise useD) will inevitably be for bad purpose25. The tone of the author in this passage is _____.A) positiveB) negativeC) factualD) criticalPassage TwoQuestions 26 to 30 are based on the following passage.Americans have always been ambivalent in their attitudes toward education. On the one hand, free and universal public education was seen as necessary in a democracy, for how else would citizens learn how to govern themselves in aresponsible way? On the other hand, America was always a country that offered financial opportunities for which education was not needed： on the road from rags to riches, schooling-beyond the basics of reading, writing, andarithmetic-was an unnecessary detour.Even today, it is still possible for people to achieve financial success without much education, but the number of situations in which this is possible is decreasing. Intoday's more complex world, the opportunities for financial success is closely related to the need for education, especially higher education.Our society is rapidly becoming one whose chief productis information, and dealing with this information requires more and more specialized education. In other words, we growup learning more and more about fewer and fewer subjects.In the future, this trend is likely to continue. Tomorrow's world will be even more complex than today's world, and, to manage this complexity, even more specialized education will be needed.26. The topic treated in this passage is _____.A) education in generalB) Americans' attitudesC) higher educationD) American education27. Americans' attitudes toward education have always been _____.A) certain B) contradictoryC) ambitious D) unclear28. Today, financial success is closely related to the need for _____.A) higher education B) public educationC) responsible citizens D) learning the basics29. It can be inferred from the third paragraph that _____.A) information is our only productB) education in the future will be specializedC) we are entering an age of informationD) we are living in an age of information30. Which of the following is the best title for the passage?A) The History of American Education.B) The Need for Specialized Education.C) The Future of the American Educational System.D) Attitudes toward American Education.Passage ThreeQuestions 31 to 35 are based on the following passage.A growing world population and the discoveries of science may alter this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in consequence the population of the world is steadily increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.When numbers rise the extra mouths must be fed. New lands must be brought under cultivation, or land already farmed made to yield larger crops. In some areas the accessible land is so intensively cultivated that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too tiny to allow for much improvement in farming methods. Were a large part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods.There is now a race for science, technology, andindustry to keep the output of food rising faster than the number of people to be fed. New strains of crops are being developed which will thrive in unfavorable climates： there are now farms beyond the Arctic Circle in Siberia and North America; irrigation and dry-farming methods bring arid lands under the plough, dams hold back the waters of great riversto ensure water for the fields in all seasons and to provide electric power for new industries; industrial chemistry provides fertilizers to suit particular soils; aeroplanes spray crops to destroy locusts and many plant diseases. Every year some new means is devised to increase or to protect the food of the world.31. The author says that the world population is growing because _____.A) there are many rich valleys and fertile plainsB) the pattern of distribution is being alteredC) people are living longerD) new land is being brought under cultivation32. The author says that in densely populated areas the land might be more productively farmed if _____.A) the plots were subdividedB) a large part of the people moved to a different part of the countryC) industrial methods were used in farmingD) the units of land were made much larger33. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.A) producing new strains of cropsB) irrigation and dry-farming methodsC) providing fertilizersD) destroying pests and disease34. Which of these words is nearest in meaning to the word "strains"?A) types B) sizesC) seeds D) harvests35. The author's main purpose is to _____.A) argue for a belief B) describe a phenomenonC) entertain D) propose a conclusionPassage FourQuestions 36 to 40 are based on the following passage.For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological(生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.Papousek began his studies by using milk in the normal way to "reward" the babies and so teach them to carry out some simple movements, such as turning the head to one sideor the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights-and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lightsclosely although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.36. According to the author, babies learn to do things which .A) are directly related to pleasureB) will meet their physical needsC) will bring them a feeling of successD) will satisfy their curiosity37. Papousek noticed in his studies that a baby .A) would make learned responses when it saw the milkB) would carry out learned movements when it had enough to drinkC) would continue the simple movements without being given milkD) would turn its head to right or left when it had enough to drink38.

大学英语四级考试阅读模拟试题(6).doc
2019年大学英语四级考试阅读模拟试题（6）Violin prodigies, I learned, have come in distinct waves from distinct regions. Most of the great performers if the late 19th and early 20th centuries were born and brought up in Russia and Eastern Europe. I asked Isaac Stern, o ne of the world’s greatest violinists the reason for this phenomenon. It is very clear, he told me. They were all Jews(犹太人) and Jews at the time were severely oppressed and ill treated in that part of the world. They were not allowed into the professional fields, but they were allowed to achieve excellence on a concert stage. As a result, every Jewish parent’s dream was to have a child in the music school because it was a passport to the West. ?Another element in the emergence of prodigies, I found, is a society that valuesexcellence in a certain field to nurture talent. Nowadays, the most nurturing societies seem to be in the Far East. In Japan, a most competitive society, with stronger discipline than ours. says Isaac Stem, children are ready to test their limits every day in many fields, including music. When Western music came to Japan after World War Ⅱ, that music not only became part of their daily lives, but it became a discipline as well. The Koreans and Chinese as we know, are just as highly motivated as the Japanese. ?That’s a good thing, because even prodigies must work hard.Next to hard work,biological inheritance plays an important role in the making of a prodigy. J. S. Bach, for example, was the top of several generations of musicians, and four of his sons had significant careers in music.Choose correct answers to the question:1.Jewish parents in Eastern Europe longed for their children to attend music school because ______ .A) it would allow them access to a better life in the WestB) Jewish children are born with excellent musical talentC) they wanted their children to enter into the professional fieldD) it would enable the family to get better treatment in their own country2.Nurturing societies as mentioned in the passage refer to societies that ______ .A) enforce strong discipline on students who want to achieve excellenceB) treasure talent and provide opportunities for its full developmentC) encourage people to compete with each otherD) promise talented children high positions3.Japan is described in the passage as a country that attaches importance to ______ .A) all-round development. B) the learning of Western musicC) strict training of children D) variety in academic studies4.Which of the following contributes to the emergence of musical prodigies according to the passage?A) A natural gift. B) Extensive knowledge of music. C) Very early training. D) A prejudice-free society.5.Which of the following titles best summarises the main idea of the passage?A) Jewish Contribution to Music. B) Training of Musicians in the World C) Music and Society D) The Making of Prodigies 参考答案1、[A]2、[B]3、[C]4、[A]5、[D]。

2019英语四级长篇阅读段落信息匹配题及答案解析(6)
2019英语四级长篇阅读段落信息匹配题及答案解析(6) 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.How to Use a LibraryA)You’re driving your car home from work or sch001.And something goes wron9.The engine stalls out at lights，holds back as you go to pass.It needs a tune up and soon.Where do you go? The library.You can take out an auto repair manual that tells step by step how to tune up your make and model.Or your tennis game has fallen off.You’ve lost your touch atthe net.Where do you go? The library for a few books on improving your tennis form.B)“The library!”you say.“That’s where my teacher sends me to dough homework."Unfortunately, I’ve foundthat’s exactly the way many people feel.If you’re among them.you’re den ying yourself the easiest way to improve yourself, enjoy yourself and even cope with life.My first suggestion for making the most of your library is to do what I did，read and read and read.For pleasure——and for understanding.C)If it’s TV that keeps you from cultivating this delicious habit，I can offer a sure remedy.Take home from the library a stack of books that might look interestin9.Pile them on the TV set.Next time you are tempted to turn on a program you really don’t want to see，reach for a book instead.D)Over the years，people collect a mental list of books they mean to read.If you don’t have such a list，here is the suggestion.Take from the library some of the books you might have enjoyed dramatized on TV, like Remargue’s All Quiet on the Western Front，Clavell’s Shegun，Tolkien’s The Hobbit，or Victor Hugo’s Les Mise Rables.If you like what you read、you can follow up with other satisfying books by the same authors.E)Some people in their reading limit themselves to current talked—about best sellers.Oh，what they miss! The library is full of yesterday’s best sellers;and they still make compelling reading today. Some that I've enjoyed：A.B.Guthrie’s The Big Sky，Carl Van Doren’s Benjamin Franklin，Mari Sandoz’s.Old Jules，and Norman Mailer’s The Naked and the Dead.F) How do you find these or any other books you’re looking for? It’s easy—with the card catalog. Every time I go to the library——and I go more than once a week——I invariably make a beeline to the card catalog before anything else.It’s the n ucleus of any public library.The card catalog lists every book in the library by：1.author;2.title;3.subject.Let’s pick an interesting subject to look up.I have always been fascinated by astronomy.You’llbe surprised at the wealth of material you will find under “a strong my” to draw upon.And the absorbing books you didn’t know existed on it.CAUTION：Always have a pencil and paper when you use the card catal09.G) Once you jot down the numbers of the books you are interested in，you are ready to find them on theshelves.Libraries call the shelves “the stacks”.In many smaller libraries，which you’ll be using，the stacks will be open for you to browse.To me there is a special thrill in tracking down the books I want in the stacks !Forinvariably,I find books about which I knew nothin9，and these often turn out to be the very ones l need.You will find the same thing happening to you when you start to browse in the stacks.“A learned mind is the end product of browsing.”CAUTION：If you take a book from the stack s to your work desk，do not try to return it to its properplace.That’s work for the experts.If you replace it incorrectly, the next seeker won’t be able to find it.H)Some of the brightest and rmed men and women in America are the librarians who specialize in providing reference help.Introduce yourself State your problem.And be amazed at how much he p you will receive.CAUTION：Don’t waste the time of this expert by asking silly questions you ought to solve yourself.Save the reference librarian for the really big ones.I) You shot：ld also learn to use the Reader's Guide to Periodical Literature.This green—bound index is me of themost useful items in any library.It indexes all the articlesin the major magazines，including newspaper magazine supplements.Thus it provides a guide to the very latestexpert information of any subject that interests you.So ifyou want to do a really first—class job，find out which magazines your library subscribes to，then consult theReader's Guide and track down recent articles on yoursubject.When you use this wonderful tool effectively, youshow the mark of a real scholar.J) Since you can take most books home，but not magazines，take full notes when using the latter. Many libraries today provide a reprographic machine that can quickly copy pagesyou need from magazines and books.Ask about it：If you are working on a project of some size which will require repeated library visits，keep a small notebook in which you record the identification numbers of the books you will be using frequently.This will save you valuable time，because youwon’t have to consult the card catalog or search aimlessly through the stacks each time you visit for material youseek.Sol fie of the very best books in any library are the reference books，which may not be taken home.Learn whattopics they cover and how best to use them，for these booksare wonderful repositories (储藏室、资料库)of human knowledge.K) Your library can give you help on any subject.It can even be your business and legal advisor.How many times have you scratched your head over how to get a tax rebate(折扣)on your summer job? You，11 find guides to that.Want to defend yourself in traffic coup? Find out how in legal books at the library.L) Library Projects Can Be Fun and Rewardin9.Here are a few ideas：1.What are your roots? Trace your ancestors.Manylibraries specialize in genealogy.2.Did George Washington sleep nearby? Or Billy the Kid? Your library’s collection of local history books can put you on the trail.3.Cook a Polynesian feast.Or an ancient Romanbanquet.Read how in the library’s cook books.4.Take up photography.Check the library for consumer reviews of cameras before you buy.Take out books on lightin9，composition，or darkroom techniques or—you name it!M)If you haven，t detected by now my enthusiasm for libraries，let me offer two personal notes.I'm particularly pleased that in recent years two beautiful libraries havebeen named after me：a small community library in Quakertown，Pennsylvania，and the huge research library located at the University of Northern Colorado in Greeley.And I likelibraries so much that I married a librarian.46.The nucleus of any public library is the car，d catalog.47.Yesterday’s best sellers are still good for readin9，which sho uldn’t be overlooked.48.The author suggests that people should go to thelibrary for answers when things go wrong49.The Reader，s Guide is a green—bound index which provides a guide to very latest expert information of any subject that interests readers.50.The sure remedy to kick the TV habit is to take home from the library interesting books to read.51.There are various kinds of fun and rewarding projects available in different libraries.52.A notebook will help readers to record theidentification numbers of the frequently used books which can’t be taken home.53.Readers should not try to return the book taken from the stacks to their desk to its proper place.54.When asking for help，readers are suggested notasking the reference librarians silly questions they ought to solve themselves.55.When asking for help，readers are suggested notasking the reference librarians silly questions they ought to solve themselves.46.The nucleus of any public library is the card catalog.任何公共图书馆的核心都是卡片目录。
2019年6月四级仔细阅读模拟试题
2019年6月四级仔细阅读模拟试题2019年6月四级仔细阅读模拟试题In a country that defines itself by ideals, not by shared blood, who should be allowed to come work and live here? In the wake of the Sept. 11 attacks these questions have never seemed more pressing.On Dec. 11, 2001, as part of the effort to increase homeland security, federal and local authorities in 14 states staged “Operation Safe Travel”—raids on airports to arrest employees with false identification (身份证明). In Salt Lake City there were 69 arrests. But those captured were anything but terrorists, most of them illegal immigrants from Central or South America. Authorities said the undocumented workers’ illegal status made them open to blackmail (讹诈) by terrorists.Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods.Mayor Anderson said those feelings were justified to a certain extent. “We’re saying we want you to work in these places, we’re going to look the oth er way in terms of what our laws are, and then when it’s convenient for us, or when we can try to make a point in terms of national security, especially after Sept. 11, then you’re disposable. There are whole families being uprooted for all of the wrong re asons,” Anderson said.If Sept. 11 had never happened, the airport workerswould not have been arrested and could have gone on quietly living in America, probably indefinitely. Ana Castro, a manager at a Ben & Jerry’s ice cream shop at the airport had been working 10 years with the same false Social Securitycard when she was arrested in the December airport raid. Now she and her family are living under the threat of deportation (驱逐出境). Castro’s case is currently waiting to be settled. While she awaits the outcome, the government has granted her permission to work here and she has returned to her job atBen & Jerry’s.62. According to the author, the United States claims to be a nation ________.A) composed of people having different valuesB) encouraging individual pursuitsC) sharing common interestsD) founded on shared ideals63. How did the immigrants in Salt Lake City feel about “Operation Safe Travel”?A) Guilty.B) Offended.C) Disappointed.D) Discouraged.64. Undocumented workers became the target of“Operation Safe Travel” because ________.A) evidence was found that they were potentialterroristsB) most of them worked at airports under threat of terroristsC) terrorists might take advantage of their illegal statusD) they were reportedly helping hide terrorists around the airport65. By saying “...we’re going to look the other way in terms of what our laws are” (Line 2, Para. 4), Mayor Anderson means “________”.A) we will turn a blind eye to your illegal statusB) we will examine the laws in a different wayC) there are other ways of enforcing the lawD) the existing laws must not be ignored66. What do we learn about Ana Castro from the last paragraph?A) She will be deported sooner or later.B) She is allowed to stay permanently.C) Her case has been dropped.D) Her fate remains uncertain.参考答案：62. D 63. B 64. C 65.C 66. D。
2019年6月英语四级仔细阅读模拟试题
2019年6月英语四级仔细阅读模拟试题2019年6月英语四级仔细阅读模拟试题Reaching new peaks of popularity in North America is Iceberg Water, which is harvested from icebergs off the coast of Newfoundland, Canada.Arthur von Wiesenberger, who carries the title Water Master, is one of the few water critics in North America. Asa boy, he spent time in the larger cities of Italy, Franceand Switzerland, where bottled water is consumed daily. Even then, he kept a water journal, noting the brands he liked best. “My dog could tell the difference between bottled and tap water,” He says.But is plain tap water all that bad? Not at all. In fact, New York’s municipal water for more than a century wascalled the champagne of tap water and until recently considered among the best in the world in terms of both taste and purity. Similarly, a magazine in England found that tap water from the Thames River tasted better than severalleading brands of bottled water that were 400 times more expensive.Nevertheless, soft-drink companies view bottled water as the next battle-ground for market share—this despite thefact that over 25 percent of bottled water comes from tap water：PepsiCo’s Aquafina and Coca-Cola’s Dasani are both purified tap water rather than spring water.As diners thirst for leading brands, bottlers and restaurateurs salivate (垂涎) over the profits. Arestaurant’s typical mark-up on wine is 100 to 150 percent, whereas on bottled water it’s often 300 to 500 perc ent. But since water is much cheaper than wine, and many of thefancier brands aren’t available in stores, most dinersdon’t notice or care.As a result, some restaurants are turning up the pressure to sell bottled water. According to an article in The Street Journal, some of the more shameless tacticsinclude placing attractive bottles on the table for a visual sell, listing brands on the menu without prices, and pouring bottled water without even asking the diners if they want it.Regardless of how it’s sold, the popularity of bottled water taps into our desire for better health, our wish to appear cultivated, and even a longing for lost purity.57. What do we know about Iceberg Water from the passage?A) It is a kind of iced water.B) It is just plain tap water.C) It is a kind of bottled water.D) It is a kind of mineral water.58. By saying “My dog could tell the difference between bottled and tap water” (Line 4 Para.2), von Wiesenberger wants to convey the message that ________.A) plain tap water is certainly unfit for drinkingB) bottled water is clearly superior to tap waterC) bottled water often appeals more to dogs tasteD) dogs can usually detect a fine difference in taste59. The “fancier brands” (Line 3 Par a. 5) refers to ________.A) tap water from the Thames RiverB) famous wines not sold in ordinary storesC) PepsiCo’s Aquafina and Coca-Cola’s DasaniD) expensive bottled water with impressive names60. Why are some restaurants turning up the pressure to sell bottled water?A) Bottled water brings in huge profits.B) Competition from the wine industry is intense.C) Most diners find bottled water affordable.D) Bottled water satisfied diners’ desire to fashionable.61. According to passage, why is bottled water so popular?A) It is much cheaper than wine.B) It is considered healthier.C) It appeals to more cultivated people.D) It is more widely promoted in the market.参考答案：57.

2019年6月大学英语四级长篇阅读练习题12篇Section BDirections: In this section, you are going to read a passage with tenstatements attached to it. Each statement contains information given in one ofthe paragraphs. Identify the paragraph from which the information isderived.You may choose a paragraph more than once. Each paragraph is marked with aletter. Answer the questions by marking the corresponding letter on Answer Sheet2.A University Degree No Longer Confers Financial Securitylions of school-leavers in the rich world are about to bid a tearfulgoodbye to their parents and start a new life at university. Some are inspiredby a pure love of learning. But most also believe that spending three or fouryears at university--and accumulating huge debts in the process--will boosttheir chances of landing a well-paid and secure job.B.Their elders have always told them that education is the best way toequip themselves to thrive in a globalised world. Blue-collar workers will seetheir jobs outsourced and automated, the familiar argument goes. School dropoutswill have to cope with a life of cash-strapped (资金紧张的) insecurity. But thegraduate elite will have the world at its feet. There is some evidence tosupport this view. A recent study from Georgetown University's Centre onEducation and the Workforce argues that"obtaining apost-secondary credential (证书) is almost always worth it." Educational qualifications are tightlycorrelated with earnings: an American with a professional degree can expect topocket $3.6m over a lifetime; one with merely a high- school diploma can expectonly $1.3m. The gap between more- and less-educated earners may be widening. Astudy in 2002 found that someone with a bachelor's degree could expect to earn75% more over a lifetime than someone with only ahigh-school diploma. Today thedisparity is even greater.C.But is the past a reliable guide to the future Or are we at thebeginning of a new phase in the relationship between jobs and education Thereare good reasons for thinking that old patterns are about to change--and thatthe current recession-driven downturn (衰退) in the demand for Western graduateswill morph (改变) into something structural. The strong wind of creativedestruction that has shaken so many blue-collar workers over the past fewdecades is beginning to shake the cognitive elite as well.D.The supply of university graduates is increasing rapidly. The Chronicleof Higher Education calculates that between 1990 and 2007 the number of studentsgoing to university increased by 22% in North America, 74% in Europe, 144% inLatin America and 203% in Asia. In 2007 150m people attended university aroundthe world, including 70m in Asia. Emerging economies—specially China--arepouring resources into building universities that can compete with the elite ofAmerica and Europe. They are also producing professional- services firms snch asT ata Consulting Services and Infosys that take fresh graduates and turn theminto world-class computer programmers and consultants. The best and thebrightest of the rich world must increasingly compete with the best and thebrightest from poorer countries who are willing to work harder for lessmoney.E. At the same time, the demand for educated labor is being reconfigured(重新配置) by technology, in much the same way that the demand for agriculturallabor was reconfigured in the 19th century and that for factory labor in the20th. Computers can not only perform repetitive mental tasks much faster thanhuman beings. They can also empower amateurs to do what professionals once did:why hire a flesh-and-blood accountant to complete your tax return when Turbotax(a software package ) will do the job at a fraction of the cost And the varietyof jobs that computers can do is multiplying as programmers teach them to dealwith tone and linguistic ambiguity.F.Several economists, including Paul Krugman, have begun to argue thatpost-industrial societies will be characterized not by a relentless rise indemand for the educated but by a great "hollowing out", as mid-level jobs aredestroyed by smart machines and high-level job growth slows. David Autor, of theMassachusetts Institute of Technology (MIT), points out that the main effect ofautomation in the computer era is not that it destroysblue-collar jobs but thatit destroys any job that can be reduced to a routine. Alan Blinder of PrincetonUniversity, argues that the jobs graduates have traditionally performed are ifanything more "offshorable" than low-wage ones. A plumber or lorry-driver's jobcannot be outsourced to India. A computer programmer's can.G. A university education is still a prerequisite for entering some of thegreat industries, such as medicine, law and academia (学术界), that provide secureand well-paying jobs. Over the 20th century these industries did a wonderful jobof raising barriers to entry--sometimes for good reasons (nobody wants to beoperated on by a barber) and sometimes for self-interested ones. But theseindustries are beginning to bend the roles. Newspapers are fighting a losingbattle with the blogosphere. Universities are replacing tenure-track professorswith non-tenured staff. Law firms are contracting out routine work suchas"discovery" (digging up documents relevant to a lawsuit) to computerized-search specialists such as Blackstone Discovery. Even doctors arethreatened, as patients find advice online and treatment in Walmart's new healthcenters.H.Thomas Malone of MIT argues that thesechanges--automation, globalizafionand deregulation--may be part of a bigger change: the application of thedivision of labor to brain-work. Adam Smith's factory managers broke theproduction of pins into 18 components. In the same way, companies areincreasingly breaking the production of brain-work into ever tinier slices.TopCoder chops up IT projects into bite-sized chunks and then serves them up toa worldwide workforce of freelance coders.I.These changes will undoubtedly improve the productivity of brain-workers.They will allow consumers to sidestep (规避) the professional industries thathave extracted high rents for their services. And they will empower manybrain-workers to focus on what they are best at and contract out more tedioustasks to others. But the reconfiguration of brain-work will also make life farless cozy and predictable for the next generation of graduates.46. The creative destruction that has happened to blue-collar workers inthe past also starts to affect the cognitive elite.47. For the next generation of graduates, life will be far less comfortableand predictable with brain-work reconfigured.48. After computers are taught by programmers to deal with tone andlinguistic ambiguity, the variety of jobs they can do will increasedramatically.49. Most school-leavers believe that, despite the huge debts they owe,going to university will increase their chances of getting securejobs with highsalaries.50. Modern companies are more likely to break the production ofintellectual work into ever tinier slices.51. A scholar of Princeton University claims that the jobs traditionallytaken by graduates are more likely to be offshored thanlow-wage ones.52. The income gap between an American professional degree holder and anAmerican high-school graduate shows income is closely related to educationalqualifications.53. The changes in the division of brain-work will save consumers some highservice fees the professional organizations charge.54. Some students have always been told that. to achieve success in aglobalised world, it is most advisable to equip themselves with education.55. Emerging economies are providing a lot of resources to builduniversities to compete with the elite of America and Europe.。

Endangered Peoples
A) Today, it is not distance, but culture that separates the peoples of the world. The central question of our time may be how to deal with cultural differences. So begins the book, Endangered Peoples, by Art Davidson. It is an attempt to provide understanding of the issues affecting the world's native peoples. This book tells the stories of 21 tribes, cultures, and cultural areas that are struggling to survive. It tells each story through the voice of a member of the
tribe .Mr. Davidson recorded their words. Art Wolfe and John Isaac took pictures of them. The organization called the Sierra Club published the book.
B) The native groups live far apart in North America or South America, Africa or Asia. Yet their situations are similar. They are fighting the march of progress in an effort
to keep themselves and their cultures alive. Some of them follow ancient ways most of the time. Some follow modern ways most of the time. They have one foot in ancient world and one foot in modern world. They hope to continue to balance
between these two worlds. Yet the pressures to forget their traditions and join the modern world may be too great.
C) Rigoberta Menchu of Guatemala, the Nobel Peace Prize winner in 1992, offers her thoughts in the beginning of the book Endangered Peoples. She notes that many people claim
that native people are like stories from the past. They are ruins that have died. She disagrees strongly. She says native communities are not remains of the past. They have a future, and they have much wisdom and richness to offer the rest of
the world.
D) Art Davidson traveled thousands of miles around the world while working on the book. He talked to many people to gather their thoughts and feelings. Mr. Davidson notes that their desires are the same. People want to remain themselves~ he says. They want to raise their children the way they were raised. They want their children to speak their mother tongue, their own language. They want them to have their parents' values and customs. Mr. Davidson says the people's cries are the same： "Does our culture have to die? Do we have to disappear as a people?"
E) Art Davidson lived for more than 25 years among native people in the American state of Alaska. He says his interest
in native peoples began his boyhood when he found an ancient stone arrowhead. The arrowhead was used as a weapon to hunt food. The hunter was an American Indian, long dead. Mr.。
