2019年英语六级考试精读荟萃练习题100篇(22) Passage Twelve (We Should All Grow Fat and Be Happy)Here’s a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this ethereal creature is on a diet. She mustn’t eat this and she mustn’t that. Oh, but of course, she doesn’t want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants：it’s the surest way to an early grave. They spend a truly memorable evening together and never see each other again.What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. Some wage all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being pummeled and massaged by weird machines. The really wealthy diet-mongers pay vast sums for ‘health cures’. For two weeks they can enter a nature clinic and be starved to death for a hundred guineas a week. Don’t think it’s only the middle-aged who go in for these fads either.Many of these bright young things you see are suffering from chronic malnutrition： they are living on nothing but air, water and the goodwill of God.来源：考试大Dieters undertake to starve themselves of their own free will; so why are they so miserable? Well, for one thing, they’re always hungry. You can’t be hungry and happy at the same time. All the horrible concoctions they eat instead of food leave them permanently dissatisfied. Wonderfood is a complete food, the advertisement says. ‘Just dissolve atea spoonful in water…’. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they’re always miserable because they feel so guilty. Hunger just proves too much for them and in the end they lash out and devour five huge guilt-inducing cream cakes at a sitting. And who can blame them? At least three times a day they are exposed to temptation. What utter torture it is always watching others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice!What’s all this self-inflicted torture for? Saintly people deprive themselves of food to attain a state of grace. Unsaintly people do so to attain a state of misery. It will be a great day when all the dieters in the world abandontheir slimming courses; when they hold out their plates and demand second helpings!1.

2019六级考试标准阅读(21)
2019六级考试标准阅读(21)The American economic system is organized around a basically private-enterprise， market-oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most. Private businessmen， striving to make profits， produce these goods and services in competition with other businessmen； and the profit motive，operating under competitive pressures， largely determines how these goods and services are produced. Thus， in the American economic system it is the demand of individual consumers， coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes， that together determine what shall be produced and how resources are used to produce it.An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy， this mechanism is provided by a price system， a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to the demand， the price will be bid up and some consumers will be eliminated from the market. If， on the other hand， producing more of a commodity results in reducing its cost， this will tend to increase the supply offered by seller-producers， which in turn will lower the price and permit more consumers to buy the product. Thus， price is the regulating mechanism in the America economic system.The important factor in a private-enterprise economy is that individual are allowed to own productive resources （private property）， and they are permitted to hire labor，gain control over natural resources， and produce goods and services for sale at a profit. In the American economy， the concept of private property embraces not only the ownership of productive resources but also certain rights， including the right to determine the price of a product or to make a free contract with another private individual.。

2019年大学英语六级考试精读荟萃练习题100篇(65) Passage Thirty-five (Exploration on the Origin of Continents)The origin of continental nuclei has long been a puzzle. Theories advanced so far have generally failed to explain the first step in continent growth, or have been subject to serious objections. It is the purpose of this article to examine the possible role of the impact of large meteoritesor asteroids in the production of continental nuclei. Unfortunately, the geological evolution of the Earth’s surface has had an obliterating effect on the original composition and structure of the continents to such an extent that further terrestrial investigations have small chance of arriving at an unambiguous answer to the question of continental origin. Paradoxically, clues to the origin and early history of the surface features of the Earth may be found on the Moon and planets, rather than on the Earth, because some of these bodies appear to have had a much less active geological history. As a result, relatively primitive surface features are preserved for study and analysis. In the case of both the Moon and Mars, it is generally concludedfrom the appearance of their heavily cratered surfaces that they have been subjected to bombardment by large meteoroids during their geological history. Likewise, it would appear a reasonable hypothesis that the Earth has also been subjected to meteoroid bombardment in the past, and that very large bodies struck the Earth early in its geological history.The large crater on the Moon listed by Baldwin has a diameter of 285 km. However, if we accept the hypotheses of formation of some of the mare basins by impact, the maximumlunar impact crater diameter is probably as large as 650km. Based on a lunar analogy, one might expect several impact craters of at least 500km diameter to have been formed on Earth. By applying Baldwin’s equati on, the depth of such a crater should be about 20km. Baldwin admits that his equation gives excessive depths for large craters so that the actual depth should be somewhat smaller. Based on the measured depth of smaller lunar crater. Baldwin’s equation give s the depth of the zone of brecciation for such a crater as about 75km. The plasticity of the Earth’s mantle at the depth makes it impossible to speak of “bracciation” in the usual sense. However, local stresses may be temporarily sustained at that depth, as shown by the existence of deep-focus earthquakes. Thus, short-term effects might be expected to a depth of more than 50km in the mantle.Even without knowing the precise effects, there is little doubt that the formation of a 500-km crater would be a major geological event. Numerous authors have considered the geological implications of such an event. Donn et al. have, for example, called on the impact of continent-size bodies of sialic composition to from the original continents. Two major difficulties inherent in this concept are the lack of any known sialic meteorites, and the high probability that the energy of impact would result in a wide dissemination of sialic material, rather than its concentration at the point of impact.Gilvarry, on the other hand, called on meteoroid impact to explain the production of ocean basins. The major difficulties with this model are that the morphology of most of the ocean basins is not consistent with impact, and thatthe origin and growth of continents is not adequately explained.We agree with Donn at al. that the impact of large meteorites or asteroids may have caused continent formation, but would rather think in terms of the localized addition of energy to the system, rather than in terms of the addition of actual sialic material.1. A mare basin is[A]. a formula for determining the relationship between the depth and width of craters.[B]. a valley that is filled in when a spatial body has impact with the moon or the earth.[C]. a planetoid (small planet) created when a meteorite, upon striking the moon, breaks off a part of the moon.[D]. a dark spot on the moon, once supposed to be a sea, now a plain.2. The writer does not believe that[A]. an asteroid is larger than a meteorite.[B]. material from space, upon hitting the earth, was eventually distributed.[C]. the earth, at one time, had craters.[D]. ocean were formerly craters.3. The article is primarily concerned with[A]. the origin of continents.[B]. the relationship between astral phenomena and the moon.[C]. differences of opinion among authoritative geologists.[D]. the relationship between asteroids and meteorites.4. Sialic material refers to[A]. the broken rock resulting from the impact of a meteorite against the earth.[B]. material that exists on planets other than the earth.[C]. a composite of rock typical of continental areas of the earth.[D. material that is man-made to simulate materials that existed far back in geological history.。

2019年12月英语四六级考试阅读专项练习题及答案(21)Learn How to ListenThe people in the room were tense. Five young engineers were sitting with their boss. They were trying to settle details of an important new plant site for a major client.Suddenly one of the young engineers gave what he thought was a good solution to the problem. What he had to say was greeted by an uncomfortable silence. The boss then laughingly pointed out that the same proposal had been made and turned down some minutes before.The incident seemed funny at the time. But several months later it didn't. After the project had been successfully finished, most of the engineers who had worked on it were promoted. But the young man who had made a fool of himself at the meeting was passed over.What had happened? The young engineer swore that he had never heard the proposal made and rejected. He was right. He was a victim of a bad listening habit that he didn't know he had.Bad listening habits can hurt you a lot in your daily living. Much of your success, both in your work and social life, is related to how you listen. A number of major industries and more than twenty leading colleges have become very concerned about our bad listening habits. They have setup "listening clinics" and courses to find out what is wrong. And what to do about it! Why You Must Hear CorrectlyMy own experience as a teacher in one of these clinicshas taught me that many people who seem to be listening miss important points. Therefore, they draw wrong conclusions from what is said. That is a serious problem when you consider our attitudes toward other people and success on the job. These attitudes are shaped more by the persuasive spoken word thanby any other means of communication.What are the faulty hearing habits that hurt us in somany ways? Here are some of the more common ones I'veobserved in a close study of my many clinic students.Our minds won't wait. Our thoughts can race along fromfour to ten times.faster than most people speak. So, while we are waitingfor the words to come in, our thoughts tend to go off on a tangent(突然改变想法) And sometimes they remain away too long.Your boss, perhaps, is discussing a situation with you. You want to hear it all. But what happens? Your mind tunes out. It comes back and tunes out again. Why doesn't someonekill that fly? I wonder who just came into the other room? Suddenly a few words come through. "Since you agree with my suggestion," your boss says. . . What did he suggest? Such tuning-out gaps are common—and sometimes costly.We think we know already. We're so sure we know what the speaker is going to say that we listen with just "half an ear. "A newspaper publisher once told me how this listening habit cost him a big gum of money.A regular client telephoned an order for a new series of ads. The person taking the order simply wrote out a standard order form. Not until too late did the publisher learn that the client had wanted the new ads to be four times as large as the old. But the smaller ads had already been set in type by then. So the client decided to run them.来源：One clerk's job around that newspaper office was pretty shaky for a time.We're looking not listening. How often in introductions has a name failed to stick because your mind was in the way its owner looked or acted? For the same reason, and far more often than you may think, other information fails to come through.We are busy listeners. We try to listen while giving part of our attention to a newspaper, or a radio or TV program. Outside noises also bid for a share of our attention. No wonder we don't really "hear. "We miss the big idea. Once I gave my students a list of vocabulary words from a recording of a newscast. The students were to listen for these words and decide how they were used in context.Then I questioned them about the general content. They replied, "Oh, we weren't listening for that; we were just listening for the words. "。

2019四级考试精读荟萃100篇(1)Passage One (Clinton Is Right)President Clinton’s decision on Apr.8 to send Chinese Premier Zhu Rongji packing without an agreement on China’s entry into the World Trade Organization seemed to be a massive miscalculation. The President took a drubbing from much of the press, which had breathlessly reported that adeal was in the bag. The Cabinet and Whit House still appeared divided, and business leaders were characterized as furious over the lost opportunity. Zhu charged that Clinton lacked “the courage” to reach an accord. And when Clinton later telephoned the angry Zhu to pledge a renewed effort at negotiations, the gesture was widely portrayed as a flip-flop.In fact, Clinton made the right decision in holding out for a better WTO deal. A lot more horse trading is needed before a final agreement can be reached. And without the Administration’s goal of a “bullet-proof agreement” that business lobbyists can enthusiastically sell to a Republican Congress, the whole process will end up in partisan acrimony that could harm relations with China for years.THE HARD PART. Many business lobbyists, while disappointed that the deal was not closed, agree that better terms can still be had. And Treasury Secretary Robert E. Rubin, National Economic Council Director Gene B. Sperling, Commerce Secretary William M. Daley, and top trade negotiator Charlene Barshefsky all advised Clinton that while the Chinese had made a remarkable number of concessions, “we’re not there yet,” according to senior officials.Negotiating with Zhu over the remaining issues may bethe easy part. Although Clinton can signal U.S. approval for China’s entry into the WTO himself, he needs Congress togrant Beijing permanent most-favored-nation status as part of a broad trade accord. And the temptation for meddling on Capital Hill may prove over-whelming. Zhu had barely landed before Senate Majority Leader Trent Lott (R-Miss) declared himself skeptical that China deserved entry into the WTO. And Senators Jesse A. Helms (R-N.C.) and Emest F. Hollings (D-S. C.) promised to introduce a bill requiring congressional approval of any deal.The hidden message from these three textile-state Southerners： Get more protection for the U. S. clothing industry. Hoping to smooth the way, the Administration tried, but failed, to budge Zhu on textiles. Also left in the lurch：Wall Street, Hollywood, and Detroit. Zhu refused to open up much of the lucrative Chinese securities market and insistedon “cultural” restrictions on American movies and music. He also blocked efforts to allow U. S. auto makers to providefleet financing.BIG JOB. Already, business lobbyists are blanketing Capitol Hill to presale any eventual agreement, but whatthey’ve heard so far isn’t encouraging. Republicans, including Lott, say that “the time just isn’t right” forthe deal. Translation：We’re determined to make it look asif Clinton has capitulated to the Chinese and is ignoring human, religious, and labor rights violations; the theft of nuclear-weapons technology; and the sale of missile parts to America’s enemies. Beijing’s fierce critics within the Democratic Party, such as Senator Paul D. Wellstone ofMinnesota and House Minority leader Richard A. Gephardt of Missouri, won’t help, either.Just how tough the lobbying job on Capitol Hill will be become clear on Apr. 20, when Rubin lectured 19chief executives on the need to discipline their Republican allies. With business and the White House still trading charges over who is responsible for the defeat of fast-track trade negotiating legislation in 1997, w orking together won’t be easy. And Republicans—with a wink—say that they’ll eventually embrace China’s entry into the WTO as a favor to Corporate America. Though not long before they torture Clinton. But Zhu is out on a limb, and if Congress overdoesthe criticism, he may be forced by domestic critics to renege. Business must make this much dear to both its GOP allies and the Whit House： This historic deal is too important to risk losing to any more partisan squabbling1. The main idea of this passage is[A]. The Contradiction between the Democratic Party and the Republican Party.[B]. On China’s entry into WTO.[C]. Clinton was right.[D]. Business Lobbyists Control Capitol Hill.2. What does the sentence “Also left in the lurch：Wall Stre et, Hollywood, Detroit” convey?[A]. Premier Zhu rejected their requirements.[B]. The three places overdid criticism.[C]. They wanted more protection.[D]. They are in trouble.3. What was the attitude of the Republican Party toward China’s entry into the WTO?[A]. Contradictory. [B].Appreciative.[C]. Disapproving. [D]. Detestful.4. Who plays the leading part in the deal in America?[A]. White House . [B]. Republicans.[C]. The Democratic Party. [D]. Businessmen.5. It can be inferred from the passage that[A]. America will make concessions.[B]. America will hold out for a better WTO[C]. Clinton has the right to signal U. S. approval for China’s entry.[D]. Democratic party approve China’s entry into the WTO.Vocabulary1. drubbing 痛打get/take a drabbing 遭人痛打2. flip-flop=great change suddenly 游说，突然改变，突然反方向。

英语六级考试阅读题专项练习及答案篇1Text 1Here's to Your HealthAs the only freshman on his school's varsity(代表队) wrestling team, Tod was anxious to fit in with his older teammates. One night after a match, he was offered a whisky bottle on the ride home. Tod felt he had to accept, or he would seem like a sissy. He took a swallow, and every time the bottle was passed back to him, he took another swallow. After seven swallows, he passed out. His terrified teammates carried him into his home, and his mother then rushed to the hospital. After his stomach was pumped, Tod learned that his blood alcohol level had been so high that he was lucky not to be in a coma or dead.Although alcohol sometimes causes rapid poisoning, frequently leads to long-term addiction, and always threatens self-control, our society encourages drinking. Many parents, by their example, give children the impression that alcohol is an essential ingredient of social gatherings. Peer pressure turns bachelor parties, fraternity initiations (同仁联谊会入会) , and spring-semester beach vacations into competitions in "getting trashed. " In soap operas, charming characters pour Scotchwhiskey from crystal bottle as readily as most people turn on the faucet for tap water. In films and rock videos, trend-setters party in nightclubs and bars. And who can recall a televised baseball or basketball game without a beer commercial? By the age of 21, the average American has been drinking on TV about 75, 000 times. Alcohol ads appear with pounding frequency—in magazines, on billboards, in college newspapers—contributing to a harmful myth about drinking.Part of the myth is that liquor signals professional success. In a men's magazine, one full-page ad for Scotch whiskey shows two men seated in an elegant restaurant. Both are in their thirties, perfectly groomed, and wearing expensive grey suits. The windows'are draped (悬挂) with velvet (天鹅绒) > the table with spotless white linen. Each place-setting consists of a long-stemmed water goblet, silver utensils and thick silver plates. On each plate is half-empty cocktail glass. The two men are grinning and shaking hands, as if they've just concluded a business deal. The caption reads, "The taste of success. "Contrary to what the liquor company would have us believe, drinking is more closely related to lack of success than to achievement. Among students, the heaviest drinkers have the lowest grades. In the work force, alcoholics are frequently late or absent, tend to perform poorly, and often get fired. Although, alcohol abuse occurs in all economic classes, it remains most severe among the poor.Another part of the alcohol myth is that drinking makes you more attractive to the opposite sex. "Hot, hot, hot," one commercial's soundtrack(电影配乐) begins, as the camera scans a crowd of college-age beachgoers. Next it follows the curve of a woman's leg up to her bare hip and lingers there. She is young,beautiful, wearing a bikini. A young guy, carrying an ice chest (箱子), positions himself near to where she sits. He is tan, muscular. She doesn't show much interest—until he opens the chest and takes out a beer. Now she smiles over at him. He raises his eyebrows and, invitingly, holds up another can. She joins him. This beer, the song concludes, "attracts like no other. "Beer doesn't make anyone sexier. Like all alcohol, it lowers the levels of male hormones in men and of female hormones in women—even when taken in small amounts. In substantial amounts, alcohol can cause infertility(不生育) in women and impotence in men. Some alcoholic men develop enlarged breasts, from their increased female hormones.The alcohol myth also creates the illusion that beer and athletics are a perfect combination. One billboard features three high-action images: a baseball player running at top speed, a surfer riding a wave, and a basketball player leaping to make a dunk shot. A particular light beer, the billboard promises, "won't slow you down. ""Slow you down" is exactly what alcohol does. Drinking plays a role in over six million injuries each year—not counting automobile accidents. Even in small amounts, alcohol dulls the brain, reducing muscle coordination and slowing reaction time. It also interferes with the ability to focus the eyes and adjust to a sudden change in brightness—such as the flash of a car's headlights. Drinking and driving, responsible for over half of all automobile deaths, is the leading cause of death among teenagers. Continued alcohol abuse can physically alter the brain, permanently damaging learning and memory. Long-term drinking is related to malnutrition, weakening of the bones, and ulcers. It increases the risk of liver failure, heart disease, andstomach cancer.Finally, according to the myth fostered by the media in our culture, alcohol generates a warm glow of happiness that unifies the family. In one popular film, the only food visible at a wedding reception is an untouched wedding cake, but beer, whiskey, and vodka flow freely. Most of the guests are drunk. After shouting into the microphone to get everyone's attention, the band leader asks the bride and groom to come forward. They are presented with two wine-filled silver drinking cups. "If you can drink your cups without spilling any wine," the band leader tells them, "you will have good luck for the rest of your lives. " The couple drain their cups without taking a breath, and the crowd cheers.A marriage, however, is unlikely to be "lucky" if alcohol plays a major role in it. Nearly two-thirds of domestic violence involves drinking. Alcohol abuse by parents is strongly tied to child neglect and juvenile delinquency. Drinking during pregnancy can lead to miscarriage and is a major cause of such birth defects as deformed limbs and mental retardation. Those who depend on alcohol are far from happy: over a fourth of the patients in state and county mental institutions have alcohol problems; more than half of all violent crimes are alcohol-related; the rate of suicide among alcoholics is fifteen times higher than among the general population.Alcohol, some would have us believe, is part of being successful, sexy, healthy, and happy. But those who have suffered from it—directly or indirectly—know otherwise. For alcohol's victims, "Here's to your health" rings with a terrible irony when it is accompanied by the clink of liquor glasses.1. The author provides lots of evidence to refute the harmful myth about drinking.2. We can conclude from the passage that the media and the culture of American society promote false beliefs about alcohol.3. Paragraph four tells us that alcoholics will never succeed if they don't quit drinking.4. Instead of making people more attractive, alcohol makes man womanlike.5. Drinking is one of the main causes of death among teenagers.6. The sentence " our society encourages drinking. " is simply based on the fact that there are so many ads for alcohol in magazines and on TV.7. Something restrain alcohol abuse before it is too late.8. Over six million injuries each year are related to______.9. The life of those who are addicted to drinking is______.10.

英语六级100篇阅读精读荟萃
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。

2019年英语六级考试精读荟萃练习题100篇(52) Passage Twenty-two (Pantomime)Pantomimes like pageants, need to be very well planned, and it is essential that initial organization should begin many weeks in advance of the production date. Pantomimes are nearly always divided into separate scenes, very often taking place in different countries or even in different centuries. It is therefore necessary that there should be an overall unity of design culminating in the grand finale. This latter is really just an excuse for visual effects, and for once the performers become merely cloths hangers on which to put elaborate garments.The scene should be discussed at some length with the producer so that the background, which is decided upon, does not present impossibilities for the provision of costumes within the budget or insuperable making problems for the wardrobe. Because of the large numbers of costumes neededfull use must be made of the cheapest materials available, such as tarlatan (thin, stiff, open-weave muslin) nets and inexpensive cottons and taffetas. Very often it is possible to pick up goods that have been substantially reduced in price as cheap lines either in the big stores or on stalls in street markets.Costumes for pantomimes need to be imaginative, gay and fairly bold in conception—this does not mean that they need to be garish. Usually in one scene there needs to be the flavor of what is newest at the moment in clothes. It is always a good idea to make use of a modern gimmick and topoint it in some way if this can be conveniently fitted into the scheme. The audience comes to pantomime to have the eye feasted as much as for any other purpose, thus making a great chance for the designer to excel. Because of the very varied audience to be catered for there must be costumes to please patrons of all ages and delight the eyes of toddlers, teenagers, parents and grandparents.Usually there is the chance for some country scene involving merry-making peasants in ginghams, stripes of chintzes. There may be a military or naval routine or some number emphasizing precision and calling for trim slick costumes. There is certain to be a ballet which is to look fairy-like or romantic and pretty and which may well need either classical or romantic tutus. The finale, which must be the most spectacular of all, is often set in a ballroom or palace where all the characters come together to make their final bows; and it is for this scene that the glitter of sequins and jewels, the sparkle of tinsel, the gold andsilver materials and the waving plumes should be saved.It may be helpful to examine the different characters and the various scenes in which they are likely to appear. They remain much the same in all pantomimes; the flavor varying according to the setting—so that a s\dash of the Orient, or the particular feeling of a historical epoch is added to the standard costume.来源：考试大的美女编辑们1.

2019英语六级考试冲刺练习：阅读篇100Although credit cards are becoming a more acceptable partof the financial scene, they are still regarded withsuspicion by many as being a major part of the "live now pay later" syndrome(^Jttt). Along with hire-purchase, rental and leasing schemes, they provide encouragement to spend more money. Of course, it is only the foolhardy who yield to the temptation to live, temporarily at least, beyond their means, and such people would no doubt manage to do so even without credit cards.Advertising campaigns have, however, promoted a growing realization of the advantages of these small pieces of plastic. They obviate (避免) need to carry large amounts of cash and are always useful in emergencies.All the credit card organizations charge interest on a monthly basis which may work out as high as 25 per cent a year, yet judicious purchasing using a card can mean that you obtain up to seven weeks, interest-free credit. Using thecard abroad, where items frequently take a long time to be included on your account, can extend this period even further.It is worthwhile shopping around before deciding on a particular credit card. It is necessary to consider the amount of credit granted; interest rates, which may vary slightly; the number and range of outlets, though most cards cover major garages, hotels, restaurants and department stores; and of course, what happens if your card is lost or stolen. A credit card thief may be sitting on a potentialgoldmine particularly if there is a delay in reporting the loss of the card.However, if used wisely, a credit card can cost nothing, or at least help to tide you over a period of financial difficulty.26. Which of the following can not make you spend more money?A. Credit cards.B. Hire-purchase.C. Rental and leasing schemes.D. None of the above is right.27. The foolhardy are people who_______.A. spend more money than they haveB. spend less money than other peopleC. save moneyD. make money28. The disadvantage of credit cards is_______.A. to enable you to buy things without carrying large amount of cashB. to encourage people to spend more moneyC. to be always useful in emergenciesD. to help people tide over a period of financial difficulty29.

2019大学英语六级阅读全真模拟题及答案汇总
2019大学英语六级阅读全真模拟题汇总卷面总分：100分答题时间：60分钟试卷题量：10题一、问答题（共10题，共100分）1.Most of us are taught to pay attention to what is said—the words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiveness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We don’t always say what we mean or mean what we say. Sometimes our words don’t mean anything except “I’m letting off some steam. I don’t really want you to pay close attention to what I’m saying. Just pay attention to what I’m feeling.”Mostly we mean several things at once. A person wanting to purchase a house says to the current owner, “This step has to be fixed before I’ll buy.”The owner says, “It’s been like that for years.”Actually, the step hasn’t been like that for years, but the unspoken message is: “I don’t want to fix it. We put up with it. Why can’t you?”The search for a more expansive view of meaning can be developed of examining a message interms of who said it, when it occurred, the related conditions or situation, and how it was said.When a message occurs can also reveal associated meaning. Let us assume two couples do exactly the same amount of kissing and arguing. But one couple always kisses after an argument and the other couple always argues after a kiss. The ordering of the behaviors may mean a great deal more than the frequency of the behavior. A friend’s unusually docile behavior may only be understood by noting that it was preceded by situations that required an abnormal amount of assertiveness. Some responses may be directly linked to a developing pattern of responses and defy logic. For example, a person who says “No!”to a serials of charges like “You’re dumb,”“You’re lazy,”and “You’re dishonest,”may also say “No!”and try to justify his or her response if the next statement is “And you’re good looking.”We would do well to listen for how messages are presented. The words, “If sure has been nice to have you over,”can be said with emphasis and excitement or ritualistically. The phrase can be said once or repeated several times. And the meanings we associate with the phrase will change accordingly. Sometimes if we say something infrequently it assumes more importance; sometimes the more we say something the less importance it assumes.1.Effective communication is rendered possible between two conversing partners, if ___.A.they use proper words to carry their ideas.B.they both speak truly of their own feelings.C.they try to understand each other’s ideas beyond words.D.they are capable of associating meaning with their words.2.“I’m letting off some steam”in paragraph 1 means___.A.I’m just calling your attention.B.I’m just kidding.C.I’m just saying the opposite.D.I’m just giving off some sound.3.The house-owner’s example shows that he actually means___.A.the step has been like that for years.B.he doesn’t think it necessary to fix the step.C.the condition of the step is only a minor fault.D.the cost involved in the fixing should be shared.4.Some responses and behaviors may appear very illogical, but are justifiable if___.A.linked to an abnormal amount of assertiveness.B.seen as one’s habitual pattern of behavior.C.taken as part of an ordering sequence.D.expressed to a series of charges.5.The word “ritualistically”in the last paragraph equals something done___.A.without true intention.B.light-heartedly.C.in a way of ceremony.D.with less emphasis.2.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 naturallybefore thunderstorm, earthquakes when winds 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 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.Vacuum 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.earthquake3.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.4.I live in the land of Disney, Hollywood and year-round sun. You 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 “happiness”. 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 newcar 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 opinion, 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.5.We can begin our discussion of “population as global issue”with what most persons mean when they discuss “the population problem”: too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ theanalogy that likened demographic growth to “a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes.”To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world’s population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.1.Which of the following demographic growth pattern is most suitable for the long thin powder fuse analogy?A.A virtually stable or slightly decreasing period and then a sudden explosion of population.B.A slow growth for a long time and then a period of rapid, dramatic increase.C.Too many people on earth and a few rapid increase in the number added each year.D.A long period when death rates exceeds birthrates and then a short period with higher fertility and lower mortality.2.During the first period of demographic history, societies were often in danger of extinction because___.A.only one in ten persons could live past 40.B.there was higher mortality than fertility in most places.C.it was too dangerous to have babies due to the poor conditions.D.our ancestors had little enthusiasm for more children.3.Which statement is true about population increase?A.There might be an increase of 2.2 billion persons from now to the year 2000.B.About 50,000 babies are born every six hours at present.C.Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.D.The population increased faster between 8000BC and 1650 than between 1650 and the present.4.The author of the passage intends to___.A.warn people against the population explosion in the near future.pare the demographic growth pattern in the past with that after 1650.C.find out the cause for rapid increase in population in recent years.D.present us a clear and complete picture of the demographic growth.5.The word “demographic”in the first paragraph means___.A.statistics of human.B.surroundings study.C.accumulation of human.D.development of human.6.Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the languages he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people. In the same way, when children learn to do all the other things they learn to do without being taught-to walk, run, climb, whistle, ride abicycle-compare those performances with those of more skilled people,and slowly make the needed changes. But in school we never give a child a chance to find out his own mistakes for himself, let alone correct them. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he becomes dependent on the teacher. Let him do it himself. Let him work out, with the help of other children if he wants it, what this word says, what answer is to that problem, whether this is a good way of saying or doing this or not.If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let’s end this nonsense of grades, exams, marks, Let us throw them all out, and let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what they know or do not know.Let them get on with this job in the way that seems sensible to them. With our help as school teachers if they ask for it. The idea that there is a body of knowledge to be learnt at school and used for the rest of one’s life is nonsense in a world as complicated and rapidly changing as ours. Anxious parents and teachers say, “But suppose they fail to learnsomething essential they will need to get in the world?”Don’t worry! If it is essential, they will go out into the world and learn it.1.What does the author think is the best way for children to learn things?A.by copying what other people do.B.by making mistakes and having them corrected.C.by listening to explanations from skilled people.D.by asking a great many questions.2.What does the author think teachers do which they should not do?A.They give children correct answers.B.They point out children’s mistakes to them.C.They allow children to mark their own work.D.They encourage children to mark to copy from one another.3.The passage suggests that learning to speak and learning to ride a bicycle are___.A.not really important skills.B.more important than other skills.C.basically different from learning adult skills.D.basically the same as learning other skills.4.Exams, grades, and marks should be abolished because children’s progress should only be estimated by___.cated persons.B.the children themselves.C.teachers.D.parents.5.The author fears that children will grow up into adults while being___.A.too independent of others.B.too critical of themselves.C.incapable to think for themselves.D.incapable to use basic skills.7.The discovery of the Antarctic not only proved one of the most interesting of all geographical 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, littlemore 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 dogsthat 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 flightsfrom 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 of human 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.8.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 someendocrine 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 stimulates the 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。
