英语六级阅读理解练习试题附答案英语六级阅读理解练习原文:What does the future hold for the problem of housing? A good deal depends, of course, on the meaning of “future”. If one is thinking in terms of science fiction and the space age, it is at least possible to assume that man will have solved such trivial and earthly problems as housing. Writers of science fiction, from H.G. Wells onwards, have had little to say on the subject. They have conveyed the suggestion that men will live in great comfort, with every conceivable apparatus to make life smooth, healthy and easy, if not happy. But they have not said what his house will be made of. Perhaps some new building material, as yet unimagined, will have been discovered or invented at least. One may be certain that bricks and mortar(泥灰,灰浆) will long have gone out of fashion.But the problems of the next generation or two can more readily be imagined. Scientists have already pointed out that unless something is done either to restrict the worlds rapid growth in population or to discover and develop new sources of food (or both), millions of people will be dying of starvation or at the best suffering from underfeeding before this century is out. But nobody has yet worked out any plan for housing these growing populations. Admittedly the worst situations will occur in the hottest parts of the world, where housing can be light structure or in backward areas where standards are traditionally low. Buteven the minimum shelter requires materials of some kind and in the teeming, bulging towns the low-standard “housing” of flattened petrol cans and dirty canvas is far more wasteful of ground space than can be tolerated.Since the war, Hong Kong has suffered the kind of crisis which is likely to arise in many other places during the next generation. Literally millions of refugees arrived to swell the already growing population and emergency steps had to be taken rapidly to preventsqualor(肮脏)and disease and the spread crime. The city is tackling the situation energetically and enormous blocks of tenements(贫民住宅)are rising at an astonishing aped. But Hong Kong is only one small part of what will certainly become a vast problem and not merely a housing problem, because when population grows at this rate there are accompanying problems of education, transport, hospital services, drainage, water supply and so on. Not every area may give the same resources as Hong Kong to draw upon and the search for quicker and cheaper methods of construction must never cease.英语六级阅读理解练习题目:1. What is the authors opinion of housing problems in the first paragraph?A. They may be completely solved at sometime in the future.B. They are unimportant and easily dealt with.C. They will not be solved until a new building material has been discovered.D. They have been dealt with in specific detail in books describing the future.2. The writer is sure that in the distant future ____.A. bricks and mortar will be replaced by some other building material.B. a new building material will have been invented.C. bricks and mortar will not be used by people who want their house to be fashionable.D. a new way of using bricks and mortar will have been discovered.3. The writer believes that the biggest problem likely to confront the world before the end of the century ___.A. is difficult to foresee.B. will be how to feed the ever growing population.C. will be how to provide enough houses in the hottest parts of the world.D. is the question of finding enough ground space.4. When the writer says that the worst situations will occur in the hottest parts of the world or in backward areas, he is referring to the fact that in these parts ___.A. standards of building are low.B. only minimum shelter will be possible.C. there is not enough ground space.D. the population growth will be the greatest.5. Which of the following sentences best summarizes Paragraph 3?A. Hong Kong has faced a serious crisis caused by millions of refugees.B. Hong Kong has successfully dealt with the emergency caused by millions of refugees.C. Hong Kongs crisis was not only a matter of housing but included a number of other problems of population growth.D. Many parts of the world may have to face the kind of problems encountered by Hong Kong and may find it much harder to deal with them. 英语六级阅读理解练习答案:AABDD。
2019年12月英语六级阅读理解100篇:旅游休闲People traveling long distances frequently have to decide whether they would prefer to go by land. sea, orair. Hardly can anyone positively enjoy sitting in a train for mort than a few hours. Train compartments soon get cramped and stuffy. Reading is only a partial solution. for the monotonous rhythm of the wheels clicking on the rails soon lulls you to sleep. During the day, sleep comes in snatches. At night when you really wish to go to sleep you rarely manage to do so. Inevitably you arrive at your destination almost exhausted. Long car journey are even less pleasant. for it is quite impossible even to read. On motorways you can. at least, travel fairly safely at high speeds, but more often than not, the greater pan of the journey is spent on narrow. bumpy roads which are crowded wich traffic. By comparison, trips by sea offer a great variety of civilized comforts. You can stretch your legs on the spacious decks, play games, swim, meet interesting people and enjoy good food-always assuming, of course, that the sea is calm. If it is not and you are likely to get seasick; no form of transport could be worse. Even if you travel in ideal weather, sea journeystake a long time. Relatively few people are prepared to sacrifice up to a third of their holidays for the pleasure of traveling on a ship.Airplanes have the reputation of being dangerous and expensive. But nothing can match them for speed and comfort. Traveling at a height of 30,000 feet. far above the clouds, and at over 500 miles an hour is an exhilarating experience. For a few hours, you settle back in a deep armchair to enjoy the flight. The real escapist can watch a free film show and sip champagne on some services. But even when such refinements are not available, there is plenty to keep you occupied. An airplane offers you an unusual and breathtaking view of the world. You soar effortlessly over high mountains and deep valleys. You really see the shape of the land. If the landscape is hidden from the view. you can enjoy the extraordinary sight of unbroken cloudplains that stretch om for miles before you, while the sun shines brilliantly in a clear sky. The journey is so smooth that there is nothing to prevent you from reading or sleeping. However you decide to spend your time, one thing is certain: you will arrive at your destination fresh and uncrumpled.1. The author indicates that reading can help lessen_______________.A) the boredom of being in the trainB) the tiresome clicking of the wheelsC) the sleeplessness during the journeyD) the poor ventilation of the compartment2. what can we leam about the long distance journey by car?A) It is safe because the car usually goes at high speeds.B) It is monotonous because reading is quite impossible.C) It is exhausting because you seldom manage to sleep.D) It is dangerous because the traffic is always too dense.3. Trips by sea is regarded as the worst means of traveling when______________.A) the weather is terribleB) the traveler has little timeC) the traveler feels seasickD) the sea is not calm4. What is the greatest difference between traveling by air and the other means of traveling?A) Traveling by air is not so tiring as the others.B) Traveling by air brings more fun than the others.C) Traveling by air is much more expensive than the others.D) Traveling by air offers more time for sleep than the others.5. By writing the passage the author intends to_______________.A) introduce diverse ways of travelingB) points out the best mode of travelingC) emphasize the advantages of traveling by airD) compare the means of relaxing when traveling答案:1. 作者指出,阅读可以帮助缓解________________。
2018年12月大学英语六级阅读100篇:生活方式I’ve heard from and talked to many people who described how Mother Nature simplified their lives for them.They’d lost their home and many or all of their possessions through tires, floods, earthquakes, or some other disaster. Losing everything you own under such circumstances can be distressing, but the people I’ve heard from all saw their loss. ultimately, as a blessing.The fire saved us the agony of deciding what to keep and what to get rid of, one woman wrote. And once all those things were no longer there, she and her husband saw how they had weighed them down and complicated their lives.There was to much stuff we never used and that was just taking up space- We vowed when we started over we’d replace only what we needed,and this time we’d do it right. We’ve kept our promise: we don’t have much now, but what we have is exactly what we want.Though we’ve never had a catastrophic loss such as that, Gibbs and I did have a close call shortly before we decided to simplify. AI that time we lived in a fire zone. One night a firestorm raged through and destroyed over six hundred homes in our community. That tragedy gave us the opportunity to look objectively atthe goods we’d accumulated.We saw that there was so much we could get rid of and not onlynever miss, but be better off without. Having almost lost it all. we found it much casier to let go of the things we knew we’d never use again.Obviously, there’s a tremendous difference between getting rid of possessions and losing them through a natural disaster without having a say in the matter. And this is not to minimize the tragedy and pain such aloss can generate.But you might think about how you would approach the acquisition process if you had to do all over again. Look around your home and make a list or what you would replace.Make another fist of things you wouldn’t acquire again no matter what, and in fact would be happy to be rid of.When you’re ready to start unloading some of your stuff, th at list will be a good place to start.l.Many people whose possessions were destroyed in natural disasters eventually considered their loss________________.2.After all their possessions were last in the fire, the woman and her husband felt that their lives were____________________.3.What do we know about the author’s house from the sentence Gibbs and I did have a close call... (Lines 1-2, Para.4.)?4.According to the author, getting rid of possessions and losing them through a natural disaster are vastly____________________.5.What does the author suggest people do with unnecessary things?答案:1.[a blessing][定位]根据their loss查找到首段末句。
六级考试标准阅读160篇第一篇(Unit one Passage 1)I live in the land of Disney, Hollywood and year-round sun. Y ou may think people in such a glamorous, fun-filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness.Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more abiding emotion.Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends.I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful individuals have constant access to glamorous parties, fancy cars, expensive homes, everything that spells “happine ss”. But in memoir after memoir, celebrities reveal the unhappiness hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages, troubled children and profound loneliness.Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he’s honest, he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure and excitement. Marriage has such moments, but they are not its most distinguishing features.Similarly, couples that choose not to have children are deciding in favor of painless fun over painful happiness. They can dine out ever they want and sleep as late as they want. Couples with infant children are lucky to get a whole night’s sleep or a three-day vacation. I don’t know any parent who would choose the word fun to describe raising children.Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations we can ever come to. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those rich and glamorous people we were so sure are happy because they are always having so much fun actually may not be happy at all.1.Which of the following is true?A.Fun creates long-lasting satisfaction.B.Fun provides enjoyment while pain leads to happiness.C.Happiness is enduring whereas fun is short-lived.D.Fun that is long-standing may lead to happiness.2.To the author, Hollywood stars all have an important role to play that is to __.A.rite memoir after memoir about their happiness.B.tell the public that happiness has nothing to do with fun.C.teach people how to enjoy their lives.D.bring happiness to the public instead of going to glamorous parties.3.In the author’s opinio n, marriage___.A.affords greater fun.B.leads to raising children.C.indicates commitment.D.ends in pain.4.Couples having infant children___.A.are lucky since they can have a whole night’s sleep.B.find fun in tucking them into bed at night.C.find more time to play and joke with them.D.derive happiness from their endeavor.5.If one get the meaning of the true sense of happiness, he will__.A.stop playing games and joking with others.B.make the best use of his time increasing happiness.C.give a free hand to money.D.keep himself with his family.第一篇答案:CBCDB第二篇(Unit one Passage 2)Once it was possible to define male and female roles easily by the division of labor. Men worked outside the home and earned the income to support their families, while women cooked the meals and took care of the home and the children. These roles were firmly fixed for most people, and there was not much opportunity for women to exchange their roles. But by the middle of this century, men’s and women’s roles were becoming less firmly fixed.In the 1950s, economic and social success was the goal of the typical American. But in the 1960s a new force developed called the counterculture. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in childcare, men began to share child-raising tasks with their wives. In fact, some young men and women moved to communal homes or farms where the economic and childcare responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam.In terms of numbers, the counterculture was not a very large group of people. But its influence spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on “overtime” work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods.In the 1970s, the feminist movement, or women’s liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women’s jobs as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion.Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these transformations.1.Which of the following best express the main idea of Paragraph 1?A.Women usually worked outside the home for wages.B.Men and women’s roles were easily exchanged in the past.C.Men’s roles at home were more firmly fixed than women’s.D.Men and women’s roles were usually quite separated in the past.2.Which sentence best expresses the main idea of Paragraph 2?A.The first sentence.B.The second and the third sentences.C.The fourth sentence.D.The last sentence.3.In the passage the author proposes that the counterculture___.A.destroyed the United States.B.transformed some American values.C.was not important in the United States.D.brought people more leisure time with their families.4.It could be inferred from the passage that___.A.men and women will never share the same goals.B.some men will be willing to exchange their traditional male roles.C.most men will be happy to share some of the household responsibilities with their wives.D.more American households are headed by women than ever before.5.The best title for the passage may be ___.A.Results of Feminist MovementsB.New influence in American LifeC.Counterculture and Its consequenceD.Traditional Division of Male and Female Roles.第二篇答案DCBCB第三篇(Unit one Passage 3)Recent research has claimed that an excess of positive ions in the air can have an ill effect on people’s physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm, earthquakes when w inds such as the Mistral, Hamsin or Sharav are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibres, or from TV sets, duplicators or computer display screens.When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea or even mental disturbance. Animals are also affected, particularly before earthquakes, snakes have been observed to come out of hibernation, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California.Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls.To increase the supply of negative ions indoors, some scientists recommend the use of ionisers: small portable machines, which generate negative ions. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.1.What effect does exceeding positive ionization have on some people?A.They think they are insane.B.They feel rather bad-tempered and short-fussed.C.They become violently sick.D.They are too tired to do anything.2.In accordance with the passage, static electricity can be caused by___.ing home-made electrical goods.B.wearing clothes made of natural materials.C.walking on artificial floor coverings.D.copying TV programs on a computer.3.A high negative ion count is likely to be found___.A.near a pound with a water pump.B.close to a slow-flowing river.C.high in some barren mountains.D.by a rotating water sprinkler.4.What kind of machine can generate negative ions indoors?A.Ionisers.B.Air-conditioners.C.Exhaust-fansD.V acuum pumps.5.Some scientists believe that___.A.watching animals to anticipate earthquakes is more effective than depending on seismography.B.the unusual behavior of animals cannot be trusted.C.neither watching nor using seismographs is reliable.D.earthquake第三篇答案BCDAA第四篇(Unit one Passage 4)A study of art history might be a good way to learn more about a culture than is possible to learn in general history classes. Most typical history courses concentrate on politics, economics, and war. But art history focuses on much more than this because art reflects not only the political values of a people, but also religious beliefs, emotions, and psychology. In addition, information about the daily activities of our ancestors—or of people very different from our own—can be provided by art. In short, art expresses the essential qualities of a time and a place, and a study of it clearly offer us a deeper understanding than can be found in most history books.In history books, objective information about the political life of a country is presented; that is, facts about politics are given, but opinions are not expressed. Art, on the other hand, is subjective: it reflects emotions and opinions. The great Spanish painter Francisco Goya was perhaps the first truly “political” artist. In his well-known painting The Third of May 1808, he criticized theSpanish government for its misuse of power over people. Over a hundred years later, symbolic images were used in Pablo Picasso’s Guernica to express the horror of war. Meanwhile, on another continent, the powerful paintings of Diego Rivera, Jose Clemente Orozco, and David Alfaro Siqueiros—as well as the works of Alfredo Ramos Martines—depicted these Mexican artists’ deep anger and sadness about social problems.In the same way, art can reflect a culture’s religious beliefs. For hundreds of years in Europe, religious art was almost the only type of art that existed. Churches and other religious buildings were filled with paintings that depicted people and stories from the Bible. Although most people couldn’t read, they could still understand biblical stories in the pictures on church walls. By contrast, one of the main characteristics of art in the Middle East was (and still is) its absence of human and animal images. This reflects the Islamic belief that statues are unholy.1.More can be learned about a culture from a study of art history than general history because art history__.A.show us the religious and emotions of a people in addition to political values.B.provide us with information about the daily activities of people in the past.C.give us an insight into the essential qualities of a time and a place.D.all of the above.2.Art is subjective in that__.A.a personal and emotional view of history is presented through it.B.it can easily rouse our anger or sadness about social problems.C.it will find a ready echo in our hearts.D.both B and C.3.Which of the following statements is true according to the passage?A.Unlike Francisco Goya, Pablo and several Mexican artists expressed their political opinions in their paintings.B.History books often reveal the compilers’ political views.C.Religious art remained in Europe for centuries the only type of art because most people regarded the Bible as the Holy Book.D.All the above mentioned.4.The passage is mainly discussing__.A.the difference between general history and art history.B.The making of art history.C.What can we learn from art.D.The influence of artists on art history.5.In may be concluded from this passage that__.A.Islamic artists have had to create architectural decorations with images of flowers or geometric forms.B.History teachers are more objective than general history.C.It is more difficult to study art history than general history.D.People and stories from the Bible were painted on churches and other buildings in order to popularize the Bible.第四篇答案:DDDCA第五篇(Unit 2 Passage 1)If the old maxim that the customer is always right still has meaning, then the airlines that ply the world’s busiest air route between London and Paris have a flight on their hands.The Eurostar train service linking the UK and French capitals via the Channel Tunnel is winning customers in increasing numbers. In late May, it carried its one millionth passenger, having run only a limited service between London, Paris and Brussels since November 1994, starting with two trains a day in each direction to Paris and Brussels. By 1997, the company believes that it will be carrying ten million passengers a year, and continue to grow from there.From July, Eurostar steps its service to nine trains each way between London and Paris, and five between London and Brussels. Each train carries almost 800 passengers, 210 of them in first class.The airlines estimate that they will initially lose around 15%-20% of their London-Paris traffic to the railways once Eurostar starts a full service later this year (1995), with 15 trains a day each way.A similar service will start to Brussels. The damage will be limited, however, the airlines believe, with passenger numbers returning to previous levels within two to three years.In the short term, the damage caused by the 1 million people-levels traveling between London and Paris and Brussels on Eurostar trains means that some air services are already suffering. Some of the major carriers say that their passenger numbers are down by less than 5% and point to their rivals-Particularly Air France-as having suffered the problems. On the Brussels route, the railway company had less success, and the airlines report anything from around a 5% drop to no visible decline in traffic.The airlines’ opti mism on returning traffic levels is based on historical precedent. British Midland, for example, points to its experience on Heathrow Leeds Bradford service which saw passenger numbers fold by 15% when British Rail electrified and modernized the railway line between London and Y orkshire. Two years later, travel had risen between the two destinations to the point where the airline was carrying record numbers of passengers.1.British airlines confide in the fact that__.A.they are more powerful than other European airlines.B.their total loss won’t go beyond a drop of 5% passengers.C.their traffic levels will return in 2-3 years.D.traveling by rail can never catch up with traveling by air.2.The author’s attitude towards the drop of passengers may be descr ibed as__.A.worried.B.delightedC.puzzled.D.unrivaled.3.In the passage, British Rail (Para 6) is mentioned to__.A.provide a comparison with Eurostar.B.support the airlines’ optimism.C.prove the inevitable drop of air passengers.D.call for electrification and modernization of the railway.4.The railway’s Brussels route is brought forth to show that__.A.the Eurostar train service is not doing good business.B.the airlines can well compete with the railway.C.the Eurostar train service only caused little damage.D.only some airlines, such as Air France, are suffering.5.The passage is taken from the first of an essay, from which we may well predict that in the following part the author is going to__.A.praise the airlines’ clear-mindedness.B.warn the airlines of high-speed rail services.C.propose a reduction of London/Paris flights.D.advise the airlines to follow British Midland as their model.第五篇答案:CABCB第六篇(Unit 2 Passage 2)Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changing sensitivity to some hormones are essential aspects of the phenomena of aging.Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulatesthe pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secret chemical agents that are conveyed by the bloodstream and regulate distant target organs or tissues. Bayliss and starling demonstrated that chemical integration could occur without participation of the nervous system.The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excite or set in motion. The term “endocrine” was introduced shortly thereafter “Endocrine” is used to refer to glands that secret products into the bloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands that secret their products though ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through a duct into the intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless.1.What is the author’s main purpose in the passage?A.To explain the specific functions of various hormones.B.To provide general information about hormones.C.To explain how the term “hormone” evolved.D.To report on experiments in endocrinology.2.The passage supports which of the following conclusions?A.The human body requires large amounts of most hormones.B.Synthetic hormones can replace a person’s natural supply of hormones if necessary.C.The quantity of hormones produced and their effects on the body ar e related to a person’s age.D.The short child of tall parents very likely had a hormone deficiency early in life.3.It can be inferred from the passage that before the Bayliss and Starling experiments, most people believed that chemical integration occurred only___.A.during sleep.B.in the endocrine glands.C.under control of the nervous system.D.during strenuous exercise.4.The word “liberate” could best be replaced by which of the following?A.EmancipateB.DischargeC.SurrenderD.Save5.According to the passage another term for exocrine glands is___.A.duct glandsB.endocrine glandsC.ductless glandsD.intestinal glands.第六篇答案:BDCBA第七篇(Unit 2 Passage 3)The discovery of the Antarctic not only proved one of the most interesting of all geograph ical adventures, but created what might be called “the heroic age of Antarctic exploration”. By their tremendous heroism, men such as Shakleton, Scott, and Amundsen caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modern science and inventions are revolutionizing the endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogs that earlier discoverers found so invaluable and hardly comparable.Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the maping of the whole of the interior presents a formidable task to the cartographers who undertake the work. Once their labors are completed, it will be possible to prospect the vast natural resources which scientists believe will furnish one of the largest treasure hoards of metals and minerals the world has yet known, and almost inexhaustible sources of copper, coal, uranium, and many other ores will become available to man. Such discoveries will usher in an era of practical exploitation of the Antarctic wastes.The polar darkness which hides this continent for the six winter months will be defeated by huge batteries of light, and make possible the establishing of air-fields for the future inter-continental air services by making these areas as light as day. Present flying routes will be completely changed, for the Antarctic refueling bases will make flights from Australia to South America comparatively easy over the 5,000 miles journey.The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has shown that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his parties were men who had never seen snow before, and yet he records that they survived the rigors of the Antarctic climate comfortably, so that, provided that the appropriate installations are made, we may assume that human beings from all countries could live there safely. Byrd even affirms that it is probably the most healthy climate in the world, for the intense cold of thousands of years has sterilize this continent, and rendered it absolutely germfree, with the consequences that ordinary and extraordinary sickness and diseases from which man suffers in other zones with different climates are here utterly unknown. There exist no problems of conservation and preservation of food supplies, for the latter keep indefinitely without any signs of deterioration; it may even be that later generations will come to regard the Antarctic as the natural storehouse for the whole world.Plans are already on foot to set up permanent bases on the shores of this continent, and what so few years ago was regarded as a “dead continent” now promises to be a most active center ofhuman life and endeavor.1.When did man begin to explore the Antarctic?A.About 100years ago.B.In this century.C.At the beginning of the 19th century.D.In 1798.2.What must the explorers be, even though they have modern equipment and techniques?A.Brave and toughB.Stubborn and arrogant.C.Well-liked and humorous.D.Stout and smart.3.The most healthy climate in the world is___.A.in South America.B.in the Arctic Region.C.in the Antarctic Continent.D.in the Atlantic Ocean.4.What kind of metals and minerals can we find in the Antarctic?A.Magnetite, coal and ores.B.Copper, coal and uranium.C.Silver, natural gas and uranium.D.Aluminum, copper and natural gas.5.What is planned for the continent?A.Building dams along the coasts.B.Setting up several summer resorts along the coasts.C.Mapping the coast and whole territory.D.Setting up permanent bases on the coasts.第六篇答案:BDCBA第七篇(Unit 2 Passage 3)The discovery of the Antarctic not only proved one of the most interesting of all geographical adv entures, but created what might be called “the heroic age of Antarctic exploration”.

Such discoveries will usher in an era of pra ctical exploitation of the Antarctic wastes.The polar darkness which hides this continent for the six winter months will be defeated by huge b atteries of light, and make possible the establishing of air-fields for the future inter-continental ai r services by making these areas as light as day. Present flying routes will be completely change d, for the Antarctic refueling bases will make flights from Australia to South America comparative ly easy over the 5,000 miles journey.The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has show n that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his parties were men who had never seen snow before, and yet he records that t hey survived the rigors of the Antarctic climate comfortably, so that, provided that the appropriat e installations are made, we may assume that human beings from all countries could live there safe ly. Byrd even affirms that it is probably the most healthy climate in the world, for the intense col d of thousands of years has sterilize this continent, and rendered it absolutely germfree, with the c onsequences that ordinary and extraordinary sickness and diseases from which man suffers in othe r zones with different climates are here utterly unknown. There exist no problems of conservatio n and preservation of food supplies, for the latter keep indefinitely without any signs of deteriorati on; it may even be that later generations will come to regard the Antarctic as the natural storehous e for the whole world.Plans are already on foot to set up permanent bases on the shores of this continent, and what so fe w years ago was regarded as a “dead continent” now promises to be a most active center of huma n life and endeavor.1.When did man begin to explore the Antarctic?A.About 100years ago.B.In this century.C.At the beginning of the 19th century.D.In 1798.2.What must the explorers be, even though they have modern equipment and techniques?A.Brave and toughB.Stubborn and arrogant.C.Well-liked and humorous.D.Stout and smart.。
2019年12月英语六级阅读理解100篇:家庭生活Divorce doesn't necessarily make adults happy. But toughing it out in an unhappy marriage until it turns around just might do, a new study says.The research identified happy and unhappy spouses. culled (选出) from a national database. Of the unhappypartners who divorced. about half were happy five years later. But unhappy spouses who stuck it out often did better. About two-thirds were happy five years later. Study results contradict what seems to be commonsense, says David Blankenhorn of the Institute for American Values, a think-tank on the family. The institute helped sponsor the research leam based at the University of Chicago. Findings will be presented in Arlington, Va.. at the "Smart Marriage" conference. sponsored by the Coalition for Marriage. Families and Couples Education.The study looked at data on 5,232 married adults from the National Survey of Families and Households. It included .64.5 who were unhappy. The adults in the national sample were analyzed through 13 measures of psychological well being. Within the five years, 167 of the unhappy weredivorced or separated and 478 stayedmarried.Divorce didn't reduce symptoms of depression, raise self-esteem or increase sense of mastery compared withthose who stayed married, the report says.Results were controlled for factors including race, age, gender and income. Staying married did not tend to trap unhappy spouses in violent relationships. What helped the unhappy married turn things around? To supplement the formal study data, the research team asked professional firms to recruit focus groups totaling 55 adults who were "marriage survivors". All had moved from unhappy to happy marriages. These 55 once-discontented married felt their unions got better via one of three routes, the report says: Marital endurance. "Wich time, job situations improved, children got older or better. or chronic ongoing problems got put into new perspective." Partners did not work on their marriages.Marital work. Spouses actively worked "to solve problems, change behavior of improve communication".Personal change. Partners found "alternative ways to improve their own happiness and build a good and happy life despite a mediocre marriage." In effect the unhappy partner changed.1. According to David Blankenhorn. people commonly believe that________.A) divorce is a better solution to an unhappy marriage than staying togetherB) divorce is not necessarily the only solution to an unhappy marriageC) keeping an unhappy marriage needs much courage and enduranceD) to end an unhappy marriage or not is a tough decision for the spouses2.

2019年12月英语六级阅读理解100篇:人文知识People have wondered for a long time how their personalities and behaviors arc formed.It's not easy to explain why one person is intelligent and another is not. or why one is cooperative and another is competitive.Social scientists are, of course, extremely interested in these types of question. They want to explain why we possess certain characteristics and exhibits certain behaviors. There are no clear answers yet, but two distinct schools of thought on thee matter have developed. As one might expect the two approaches are very different from one another. and there is a great deal of debate between proponents of each theory. Thecontroversy is often conveniently referred to as"nature/nurture".Those who support the "nature" side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factor. That our environment has little. if anything to do with our abilities. characteristics. and behavior is central to this theory. Taken to an extreme, this theory Maintains that our behavior is predetermined to such a great degree that we arealmost completely governed by our instincts.Proponents of the "nurture" theory, or, as they are often called. behaviorists. claim that our environmentis more important than our biologically based instincts in determining how we will act. Behaviorists see humans as being whose behavior is almost completely shaped by their surroundings. Their view of the human being is quite mechanistic; they maintain that like machines. humans respond to environmental stimuli as the basis of their behavior.The social and political implications or these two theories are profound. In the United Stares, for example, blacks often score below whites on standardized intelligent test. This leads some "nature" proponents to conclude that blacks are genetically interior to whites. Behaviorists, in contrast. say that the differences in scores are due to the fact that blacks are often deprived of many of the educational and other environmental advantages that white enjoy. and that. as a result. they do not develop the same responses thatwhites do.Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes. That the controversy will continue for a long time is certain.1. The author is mainly concerned about solving the problem__________________.A) why one's behaviors differ from others'B) what makes different stages of intelligenceC) how social scientists form different theoriesD) what causes the "nature/nurture" controversy2. The word "proponents" can best be replaced by _____.A) approachesB) advocatesC) principlesD) characters3. Which of the following statements may be supported by the "nature" school?A) We are born will certain personalities and behaviors.B) Environment has nothing to do with our personalities.C) Abilities and characteristics are revealed by behaviors.D) Only extreme behaviors are determined by instinct.4. What can we learn about the behaviorists?A) They believe human beings are mechanical.B) They compare our behaviors to the machines.C) They suggest that we react to the environment as the machines do.D) They uphold that the mechanistic theory can be appliedon us as well.5. The "nature” theorists believe that the blacks' low scores____________.A) are the result of the educational disadvantagesB) are a manifestation of the blacks' poor intelligenceC) have nothing to do with their true intelligenceD) have nothing to do will factors other than heredity答案:1.作者主要关注于解决什么问题?A) 为什么一个人的行为与其他人的行为不一样?B) 智力发展的不同阶段是怎么形成的?C)社会科学家是如何形成不同的理论的?D) 是什么造成了“天性论,教养论”的争议?。
英语六级100篇阅读精读荟萃Passage One (Violence Can Do Nothing to Diminish Race Prejudice)In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence –as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed, the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us.The truly reasonable men who know where the solutions lie are finding it harder and herder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law.Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each other‘s problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. ‗Talk, talk, talk,‘ the advocates of violence say, ‗all you ever do is talk, and we are none the wiser.‘It‘s rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. ‗Possible, my lord,‘ the barrister replied, ‗none the wiser, but surely far better informed.‘Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.1.What is the best title for this passage?[A] Advocating Violence.[B] Violence Can Do Nothing to Diminish RacePrejudice.[C] Important People on Both Sides See Violence Asa Legitimate Solution.[D] The Instincts of Human Race Are Thirsty forViolence.2.Recorded history has taught us[A] violence never solves anything.[B] nothing.[C] the bloodshed means nothing.[D] everything.3.It can be inferred that truly reasonable men[A] can‘t get a hearing.[B] are looked down upon.[C] are persecuted.[D] Have difficulty in advocating law enforcement.4.―He was none the wiser‖ means[A] he was not at all wise in listening.[B] He was not at all wiser than nothing before.[C] He gains nothing after listening.[D] He makes no sense of the argument.5.According the author the best way to solve raceprejudice is[A] law enforcement.[B] knowledge.[C] nonviolence.[D] Mopping up the violent mess.V ocabulary1.acute 严重的,剧烈的,敏锐的2.loot v.抢劫,掠夺;n.赃物3.pillage v.抢劫,掠夺4.crunch v.吱嘎吱嘎咬或嚼某物;n.碎裂声when it comes to the crunch = if/when the decisive moment comes. 当关键时刻来到时。

Office workers who would normally step into a pub or gym to cope with the stress of a working day are being invited instead to sit in front of a painting. Manchester Art Gallery has recruited two of the country's leading experts in stress management to choose pictures that are guaranteed to leave even the most frantic feeling at ease wich the world.They have created the "tranquility tour" which allows city-centre workers to spend their lunch hour taking a soothing tourof what are described as "some of the most relaxing and inspiring paintings ever committed to canvas”. The free tour takes the visitor through several centuries of painting, from the Victorian aesthetic movement.through the PreRaphaelite school, to modern abstract an. Kim Gowland, a gallery executive. said: "Looking at art is a stress-relieving activity. What we are tryingto do is encourage people who work in the city to spend half an hour of their lunchbreak in the gallery. to chill out rather than rush around the shops." The five works chosen by Andrew Loukes. the gallery's manager, are: John Roddam Spencer Stanhope’s The Waters of Lethe (1880), Turner's Thomson’s Aeolian Harp (1809), Sir John Everett Millais’s Autumn Leaves (1856), James Durden’s Summer in Cumberland (1925) and Bridget Riley’s Zephyr (1976). Mr. Loukes said: "We chose five pictures that suggest restfulness. We also wamed to display the breadth of the collection. We arc particularly strong in early-19th and early-20th-century British art." Their therapeutic powers have been endorsed by Olga Gregson and Terry Looker from the Department of Biological Sciences at Manchester Metropolitan University. Dr. Gregson said that "research shows that stress levels have reduced and moods changed for the better” when subjects looked at paintings. "Although art appreciation is very much a matter of personal choice, it is true that some works of art appeal to almost everyone, and that some paintings have qualities that can induce relaxation in most people."Dr. Gregson said. "Great painters such as Leonardo da Vinci were masters of techniques that could evoke particular responses in the viewer." Dr. Gregson said the gallery represented an "oasis of calm". "You have got this wonderful opportunity to evoke a different kind of psychophysiological response." 1. What is done by the Manchester Art Gallery is intended to____________. A) find out the relation between paintings and stress-easing B) promote its magnificent collection of British art C) reduce working people's stress levels by art appreciation D) provide an alternative of pastime for consumers 2. The tour is named “tranquility tour" because__________. A) it is expected to play a soothing role B) it displays paintings through centuries C) it comprises paintings of various styles D) it only takes a half hour around lunch time 3. What does Kim Gowland points out about city-center workers? A) They are pressed by family burden as well as their careers. B) They like going shopping during their short lunchbreak. C) They shouldn't rush around the gallery while looking at art. D) Looking at art is much better than going to pubs or gyms. 4. According io the author, the painting's impact on relieving stress is__________. A) based on personal experiences B) vaned from people to people C) in need of further study D) scientifically proven 5. It is indicated by Dr. Gregson that da Vinci's paintings can____________. A) suggest restfulness B) arouse diverse feelings C) capture almost everyone D) ease stress in most people 答案: 1. 曼彻斯特美术馆所做的事情是旨在___________________. A) 找到画作和舒缓压⼒之间的关系 B) 推⼴其重要的英国艺术藏品 C) 通过艺术欣赏来帮⼈们减压 D)为顾客提供另⼀种消遣的选择 [C]原⽂第2段说明曼彻斯特美术馆雇⽤两位压⼒管理专家并且展览画作都是为了使⼈缓解压⼒,因此选项C为美术馆的⽬的。
2019年12月英语六级阅读理解100篇:教育Jefferson continued to insist that no republic could maintain itself in strength without the broad education ofits people, and he favored beginning at the bottom with elementary schools. He extolled the vital importance of education to republican government. In December 1778, he proposed the plan"for the more general diffusion of knowledge".The plan that Jefferson offered called for each county to be divided into "hundreds" and a school built ineach hundred so conveniently located that all free boys and girls might attend daily. For three years all children would receive free schooling, and any child might attend longer at private expense. Pupils would be taught reading, writing, and common arithmetic and become acquainted with Greek, Roman, English, and American history through the books used for reading. From each group of about ten elementary schools one boy"of the best and most promising genius and disposition" whose parents were too poor to continue his schooling would be chosen each year to proceed to one of the grammar schools serving several counties. He would be boarded and his tuition paid by the state. Other qualified students whose parents could support their education also would be admitted to the grammar schools, where they would be taught Latin, Greek, English grammar, geography, and advanced arithmetic. After one year, the least promising third of the state-supported scholars would be cut, and after two years only one-"the best in genius and disposition"-would be allowed to continue atpublic expense for another four years. With twenty grammar schools proposed, Jefferson envisioned "twenty of the best geniuses selected from the rubbish annually". From thisselect group, each grammar school in alternate years would send the most promising scholar to the College of William and Mary to be educated, boarded, and clothed at state expensefor three years. In a system with twenty grammar schools, ten "public foundationers" would thus annually reach the peak of the educational pyramid.The contribution of Jefferson's plan was not equal universal education but a system by which the most talented children from whatever condition of society could be given an opportunity for education. An "aristocracy of virtue and talent" thus could be recruited from all classes.Jefferson's interest in education rested on his conviction that the only way of preserving republican government and preventing those entrusted with political power from resorting to tyranny was "to illuminate, as far as practicable, the minds of thepeople at large". Also, in order to have the best laws and well-administered government, it was important that those persons "whom nature has endowed with genius and virtue" be liberally educated and called to government service "without regard to wealth,birth or other accidental condition or circumstance".1.Jefferson advised that broad education for the people should start from________________.2.Jefferson's plan was intended to help the most promising boys from__________________families.3.How long would "the best in genius and disposition" study at the grammar school?4.The contribution of Jefferson's plan was to set upa system to give all the most talentedchildren_____________________.5.Jefferson suggested that the only way to preserve republican government was to illuminate_________________.答案:1.elementary schools定位依据题干中的broad education定位到第1段第l句。

Can the Computer Learn from Experience 计算机会总结经验吗 Computers have been taught to play not only checkers, but also championship chess, which is a fairly accurate yardstick for measuring the computer’s progress in the ability to learn from experience.
Because the game requires logical reasoning, chess would seem to be perfectly suited to the computer .all a programmer has to do is give the computer a program evaluating the consequences of every possible response to every possible move, and the computer will win every time. In theory this is a sensible approach; in practice it is impossible. Today, a powerful computer can analyze 40 000 moves a second. That is an impressive speed. But there are an astronomical number of possible moves in chess—literally trillions. Even if such a program were written (and in theory it 资料来源:www.ymx.pingoushop.com www.ymx.pingoushop.com could be ,given enough people and enough time), there is no computer capable of holding that much data.
Therefore, if the computer is to compete at championship levels, it must be programmed to function with less than complete data. It must be able to learn from experience, to modify its own programm, to deal with a relatively unstructured situation—in a word, to “think” for itself . In fact, this can be done. Chess-playing computers have yet to defeat world champion chess players, but several have beaten human players of only slightly lower ranks. The computers have had programs to carry them through the early, mechanical stages of their chess games. But they have gone on from there to reason and learn, and sometimes to win the game.
There are other proofs that computers can be programmed to learn, but this example is sufficient to demonstrate the point. Granted , winning a game of chess is not an earthshaking event even when a computer does it . But there are many serious human problems which ban be fruitfully approached as games. The Defense Department uses computers to play war games and work out strategies for dealing with international tensions. Other 资料来源:www.ymx.pingoushop.com www.ymx.pingoushop.com problems—international and interpersonal relations , ecology and economics , and the ever-increasing threat of world famine—can perhaps be solved by the joint efforts of human beings and truly intelligent computers .
Notes check:a game played on a checkerboard by two players ,each using 12 pieces
ecology:the relationship between organisms and their environment 生态关系,生态学
Reading comprehension The purpose of creating chess-playing computers is __________ A to win the world chess champion B to pave the way for further intelligent computers C to work out strategies for international wars 资料来源:www.ymx.pingoushop.com www.ymx.pingoushop.com D to find an accurate yardstick for measuring computer progress 2 Today , a chess-playing computer can be programmed to ________ A give trillions of reponses in a second to each possible move and win the game
B function with complete data and beat the best players C learn from chess-playing in the early stage and go on to win the game
D evaluate every possible move but may fail to give the right response each time

You have to have lived in the 1950s and 1960s to have experienced a good economy. In the period between 1950 and 1970 it was the rule—rather than the exception—that an ordinary family, without higher education, could sustain itself decently on the income of a single breadwinner(养家糊口的人). In 1955, when I was 19 and living in Brooklyn, N. Y., my father, who had a sixth-grade education, maintained our family of five on a wage of $82 a week as a bookbinder. My mother taught us fairness and compassion; my father, discipline and enterprise.
