大学英语六级(阅读)模拟试卷2(题后含答案及解析)题型有:1. You have a wide spectrum of nutrition and lifestyle choices. It’s not all or nothing. To the degree you move in a healthful direction on this spectrum. You’re likely to feel better, look better, lose weight and gain health. People have different needs, goals and preferences. The medicine of the future is personalized medicine. What matters most is your overall way of eating and living. If you indulge yourself one day, you can eat more healthfully the next. If you’re a couch potato one day, exercise a little more the next. If you don’t have time to meditate for 20 minutes, do it for one minute —the consistency is more important than the duration. Then, you’re less likely to feel restricted. Studies have shown that those who eat the healthiest overall are the ones who allow themselves some indulgences. If you’re trying to reverse heart disease or prevent the recurrence of cancer(the “pound of cure”), then you probably need to make much bigger changes in diet and lifestyle than someone who just wants to lose a few pounds and is otherwise healthy(the “ounce of prevention”). If you want to lower your cholesterol(胆固醇)or blood pressure, you can begin by making moderate changes in diet and lifestyle. If that’s enough to achieve your goals, great; if not, then consider making bigger changes. For example, most people in this country have elevated cholesterol levels. They are initially advised to follow a diet based on the American Heart Association and National Cholesterol Education Program guidelines. For some, that’s sufficient to lower their cholesterol levels enough, but not for most people. Many are then told, “Sorry, it looks like diet didn’t work for you. “And they are prescribed cholesterol-lowering drugs, which they are told they will need to take for the rest of their lives. In reality, most people can make progressively bigger changes in nutrition and lifestyle to achieve their goals —often without medications.2. Even more than feeling healthy, most people want to feel free and in control. The food police are counterproductive. If I tell people, “Eat mis and don’t eat that,”or “Don’t smoke,”they immediately want to do the opposite. It’s just human nature, and it goes back to the first dietary intervention that failed —“Don’t eat the apple”—and that was God talking, so we’re not likely to do better than that... If you go on a diet and feel constrained, you’re likely to go off it sooner or later. Offering a spectrum of choices is much more effective; then, you feel free. If you see your food choices each day as part of a spectrum, a way of living, then you are more likely to feel empowered.3. Eating bad food does not make you a bad person. The language of behavioral modification often has a moralistic quality that turns off a lot of people(like “ cheating” on a diet). It’s a small step from thinking of foods as “good”or “bad” to seeing yourself as a “good person” or a “bad person” if you eat these. The term “patient compliance” has a fascist, creepy quality to it, sounding like one person bending his or her will to another. Food is just food.4. How you eat is as important as what you eat. If I eat mindlessly while watching television, reading or talking with someone else, I can go through an entire meal without tasting the food. The plate is empty, but I didn’t enjoy it; I had all of the calories and none of the pleasure.Instead, if I eat mindfully, paying attention to what I’m eating, smaller portions of food can be exquisitely satisfying. I can meditate on a single piece of dark chocolate. Also, when you pay attention to what you’re eating, you notice how different foods affect you, for better and for worse. More healthful foods make you feel good —light, clear, energetic. Less healthful foods make you feel bad —heavy, dull, sluggish. Then, it comes out of your own experience.5. Joy of living is a much better motivator than fear of dying. Trying to scare people into changing doesn’t work very well. Telling someone that they’re likely to have a heart attack if they eat cheeseburgers or may get lung cancer if they don’t quit smoking doesn’t work very well. Efforts to motivate people to change based on fear of getting sick or dying prematurely are generally unsuccessful. Why? It’s too scary. We all know we’re going to die one day —the mortality rate is still 100 percent —but who wants to think about it? Even someone who has had a heart attack usually changes for only a few weeks before they go back to their old patterns of living and eating. When you change your diet and lifestyle, you feel good and look good. Your brain receives more blood and oxygen, so you think more clearly, have more energy and need less sleep. Your face gets more blood flow, so your skin glows more and wrinkles less. Your heart gets more blood flow, so you have more stamina and can even begin to reverse heart disease.6. What we do eat is at least as important as what we don’t eat. There are at least a thousand substances that have anticancer, anti-heart-disease and anti-aging properties. Fruits, vegetables, whole grains, legumes, soy products and fish are rich in good carbohydrates, good fats, good proteins and other protective substances , leading to feelings of abundance rather than deprivation.7. It’s important to address the deeper issues that underlie our behaviors. Information is not usually enough to motivate lasting changes. If it were, no one would smoke. We need to work at a deeper level. In our studies, I asked people, “Why do you smoke? Overeat? Drink too much? Work too hard? Abuse substances? Watch too much television? These behaviors seem so maladaptive to me. “They would reply, “ You just don’t get it. These behaviors are very adaptive because they help us get through the day. “As I wrote in an earlier column, loneliness and depression are epidemic in our culture. If we address these deeper issues, then it becomes easier for people to make lasting changes in their behaviors.11.The author has proved the power of changes in diet and lifestyle by______.A.the most advanced technologyB.some simple measuresC.data collected all over the U. S.D.theoretical analysis正确答案:A解析:第一段末讲他们的研究表明“饮食和生活方式的变化对人的影响巨大”,第二段介绍了他们证明(prove how powerful…)这种“干预”(interventions)的威力的手段——最新的科技手段(the latest high technical measures)。
英语六级阅读理解模拟练习附答案六级阅读理解模拟练习一:Which is safer-staying at home, traveling towork on public transport,or working in the office?Surprisingly, each of these carries the same risk,which is very low. However, what about flyingcompared to working in the chemical industry?Unfortunately, the former is 65 times riskier thanthe latter! In fact, the accident rate of workers inthe chemical industry is less than that of almost anyof human activity, and almost as safe as staying at home.The trouble with the chemical industry is that when things go wrong they often cause deathto those living nearby. It is this which makes chemical accidents so newsworthy. Fortunately,they are extremely rare. The most famous ones happened at Texas City (1947),Flixborough(1974),Seveso (1976), Pemex (1984) and Bhopal (1984)。
Some of these are always in the minds of the people even though the loss of life was small.No one died at Seveso, and only 28 workers at Flixborough. The worst accident of all wasBhopal, where up to 3,000 were killed. The Texas City explosion of fertilizer killed 552. ThePemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives, justa month before the unfortunate event at Bhopal.Some experts have discussed these accidents and used each accident to illustrate aparticular danger. Thus the Texas City explosion was caused by tons of ammonium nitrate(硝酸铵),which is safe unless stored in great quantity. The Flixborough fireball was the fault ofmanagement, which tookrisks to keep production going during essential repairs. The Sevesoaccident shows what happens if the local authorities lack knowledge of the danger on theirdoorstep. When the poisonous gas drifted over the town, local leaders were incapable oftaking effective action. The Pemex fire was made worse by an overloaded site in anovercrowded suburb. The fire set off a chain reaction os exploding storage tanks. Yet, by amiracle, the two largest tanks did not explode. Had these caught fire,then 3,000 strongrescue team and fire fighters would all have died.1.Which of the following statements is true?A.Working at the office is safer than staying at home.B.Traverlling to work on public transport is safer than working at the office.C.Staying at home is safer than working in the chemical industry.D.Working in the chemical industry is safer than traveling by air.2.Chemical accidents are usually important enough to be reported as news because ____.A.they are very rareB.they often cause loss of lifeC.they always occur in big citiesD.they arouse the interest of all the readers3.According to passage, the chemical accident that caused by the fault of managementhappened at ____.A.Texas cityB.FlixboroughC.SevesoD.Mexico City4.From the passage we know that ammonium nitrate is a kind of ____.A.natural gas, which can easily catch fireB.fertilizer, which cant be stored in a great quantityC.poisonous substance, which cant be used in overcrowded areasD.fuel, which is stored in large tanks5.From the discussion among some experts we may coclude that ____.A.to avoid any accidents we should not repair the facilities in chemical industryB.the local authorities should not be concerned with the production of the chemicalindustryC.all these accidents could have been avoided or controlled if effective measure hadbeen takenD.natural gas stored in very large tanks is always safe参考答案:DBABC六级阅读理解模拟练习二:40 years ago the idea of disabled people doingsport was never heard of. But when the annualgames for the disabled were started atStokeMandeville, England in 1948 by Sir LudwigGuttmann, the situation began to change.Sir Ludwig Guttmann, who had been driven toEngland in 1939 from Nazi Germany, had been askedby the British government to set up an injuriescenter at Stoke Mandeville Hospital near London. His ideas about treating injuries includedsport for the disabled.In the first games just two teams of injured soldiers took part. The next year, 1949, fiveteams took part. From those beginnings, things have developed fast. Teams now come fromabroad to Stoke Mandeville every year. In 1960 the first Olympics for the Disabled were held inRome, in the same place as the normal Olympic Games. Now, every four years the OlympicGames for the Disabled are held, if possible, in the same place as the normal Olympic Games,although they are organized separately. In other years Games for the Disabled are still held atStoke Mandeville. In the 1984 wheelchair Olympic Games, 1064 wheelchair athletes from about40 countries took part. Unfortunately, they were held at Stoke Mandeville and not in LosAngeles, along with the other Olympics.The Games have been a great success in promoting international friendship andunderstanding, and in proving that being disabled does not mean you cant enjoy sport. Onesmall source of disappointment for those who organize and take part in the games,however, has been the unwillingness of the International Olympic Committee to includedisabled events at Olympic Games for the able-bodied. Perhaps a few more years are stillneeded to convince those fortunate enough not to be disabled that their disabled fellowathletes should not be excluded.21. The first games for the disabled were held______after Sir Ludwig Guttmann arrived inEngland.A. 40 yearsB. 21 yearsC. 10 yearsD. 9 years22. Besides Stoke Mandeville, surely the games for the disabled were once held in______.A. New YorkB. LondonC. RomeD. Los Angeles23. In Paragraph 3, the word "athletes" means______.A. people who support the gamesB. people who watch the gamesC. people who organize the gamesD. people who compete in the games24. Which of the following statements is NOT true?A. Sir Ludwig Guttmann is an early organizer of the games for the disabled.B. Sir Ludwig Guttmann is an injured soldier.C. Sir Ludwig Guttmann is from Germany.D. Sir Ludwig Guttmann is welcomed by the British government.25. From the passage, we may conclude that the writer is ______.A. one of the organizers of the game for the disabledB. a disabled person who once took part in the gamesC. against holding the games for the disabledD. in favor of holding the games for the disabled 参考答案:21.

英语六级阅读理解全真模拟练习英语六级阅读理解全真模拟练习二: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 dont always say what we mean or mean what we say. Sometimes our words dont mean anything except “ Im letting off some steam. I dont really want you to pay close attention to what Im saying. Just pay attention to what Im 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 Ill buy.” The owner says, “ Its been like that for years.” Actually, the step hasnt been like that for years, but the unspoken message is: “ I dont want to fix it. We put up with it. Why cant you?” The search for a more expansive view of meaning can be developed of examining a message in terms 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 dealmore than the frequency of the behavior. A friends 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 “Youre dumb,”“Youre lazy,” and “Youre dishonest,” may also say “No!” and try to justify his or her response if the next statement is “And youre 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 others ideas beyond words.D.they are capable of associating meaning with their words.2.“Im letting off some steam” in paragraph 1 means___.A.Im just calling your attention.B.Im just kidding.C.Im just saying the opposite.D.Im just giving off some sound.3.The house-owners example shows that he actually means___.A.the step has been like that for years.B.he doesnt 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 ones 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.答案:DBABC。

Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.?Passage 1Questions 11 to 15 are based on the following passage:?In a sense, the new protectionism is not protectionism at all, at least not in the traditional sense of the term. The old protectionism referred only to trade restricting and trade expanding devices, such as the tariff or export subsidy. The new protectionism is much broader than this: it includes interventions into foreign trade but is not limited to them. The new protectionism, in fact, refers to how the whole of government intervention into the private economy affects international trade. The emphasis on trade is still there, thus came the term “protection.” But what is new is the realization that virtually all government activities can affect international economic relations.?The emergence of the new protectionism in the Western world reflects the victory of the interventionist, or welfare economy over the market economy. Jab Tumiler writes,“The old protectionism…coexisted, without any apparent intellectual difficulty with the acceptance of the market as a national as well as an international economic distribution mechanism — indeed,protectionists as well as (if not more than) free traders stood for laissez faire(放任政策). Now, as in the 1930s, protectionism is an expression of a profound skepticism as to the ability of the market to distribute resources and incomes to societies sat。

大学英语六级改革适用(长篇阅读)模拟试卷2(题后含答案及解析) 题型有: 4. Reading ComprehensionPart III Reading ComprehensionSection BThe Happiness Effect[A]The next time you get the flu, there will almost certainly be someone you can blame for your pain. There’s the inconsiderate co-worker who decided to drag himself to the office and spent the day sniffling, sneezing and shivering in the cubicle next to yours. Or your child’s best friend, the one who showed up for a playdate with a runny nose and a short supply of tissues. Then there’s the guy at the gym who spent more time sneezing than sweating on the treadmill before you used it.[B]You’re right to pass the blame. Pathogens(致病菌)like the influenza virus pass like a holiday fruitcake from person to person, but you probably don’t think much past the one who gave it directly to you. An infectious-disease expert, on the other hand, would not be satisfied to stop there. What about the person who passed the virus on to your colleague, the one before him and others earlier still? Contagious(传染性的)diseases operate like a giant infectious network, spreading like the latest YouTube clip among friends of friends online. We’re social animals; we share.[C]So public-health experts are beginning to wonder whether certain health-related behaviors are just as contagious as microbes. If you’re struggling with your weight, did you in effect catch a case of fat by learning poor eating and exercise habits from a friend or family member who was similarly infected by someone else? If you smoke, do you light up because you were behaviorally contaminated by smokers who convinced you of the coolness of the habit? Even more important, if such unhealthy behaviors are contagious, are healthy ones —like quitting smoking or exercising —equally so? And what if not only behaviors but also moods and mental states work the same way? Can you catch a case of happy?[D]Increasingly, the answer seems to be yes. That’s the intriguing conclusion from a body of work by Harvard social scientist Dr. Nicholas Christakis and his political-science colleague James Fowler at the University of California at San Diego. The pair created a sensation with their announcement earlier this month of a 20-year study showing that emotions can pass among a network of people up to three degrees of separation away, so your joy may, to a larger extent than you realize, be determined by how cheerful your friends’ friends’ friends are, even if some of the people in this chain are total strangers to you.[E]If that’s so, it creates a whole new paradigm for the way people get sick and, more important, how to get them healthy. It may mean that an individual’s well-being is the product not just of his behaviors and emotions but more of the way they feed into a larger social network. Think of it as health Facebook-style. “We have a collective identity as a population that transcends individual identity,”says Christakis. “This superorganism has an anatomy(解剖学),physiology, structure and function that we are trying to understand.”[F]In their most recent paper, published in the British Medical Journal, Christakis and Fowler explored the emotional state of nearly 5,000 people and the more than 50,000 social ties they shared. At three points during the long study, all the participants answered a standard questionnaire to determine their happiness level, so that the scientists could track changes in emotional state.[G]That led to their intriguing finding of just how contagious happiness can be: if a subject’s friend was happy, that subject was 15% more likely to be happy too; if that friend’s friend was happy, the original subject was 10% more likely to be so. Even if the subject’s friend’s friend’s friend —entirely unknown to the subject —was happy, the subject still got a 5.6% boost. The happiness chain also worked in the other direction, radiating from the subject out to his friends.[H]The happiness dividend is more powerful if two people not only know each other but also are equally fond of each other. Happiness is more infectious in mutual relationships(in which both people name the other as a friend)than in unreciprocated ones(in which only one is named).[I]And it’s not just in sterile(枯燥乏味的)study settings that the contagion of happiness is spreading. Christakis and Fowler noticed that people who are smiling on their Facebook pages tend to cluster together, forming an online social circle like a delirious flock of cyberbirds. And while some of this joy can certainly be traced to the copycat effect —if your friends post smiling pictures, you might feel like a grouch(不高兴的人)if you don’t too —Christakis and Fowler are analyzing the clusters to see if something more infectious might be at work.[J]Skeptics raise other concerns, ones that go beyond the copycat effect. Couldn’t happy people simply be exposed to similar lifestyles or social factors that explain their shared joy, such as favorable weather, low unemployment rates or a winning baseball team? If that were the case, argue the authors, then happiness would spread more uniformly among all the relationships; instead, it varied depending on whether the friendship was mutual or merely one-sided. As the investigators teased out these factors, they found that environment didn’t have nearly the power that relationships did.[K]The infectiousness of happiness is only the latest in a series of similar phenomena Christakis and Fowler have stud-ied. In 2007 they published a paper showing that obesity travels across webs in a similar way, with individuals having a 57% greater risk of being overweight if they have an obese friend. The same holds true for quitting smoking, with success 30% more common among friends of quitters than among friends of smokers.[L]In all these cases, there’s a predictable topography(地形)to how people influence one another, one that can be reduced to a sort of social map. People who are central to their networks —who in effect are the hub through which most of the other relationships or information flows —may have the most influence on others and in turn are the most influenced by them. But just because you start off at the center of your web does not guarantee that you’ll stay there. In the 1970s, smokers were more likely to occupy that focal position in their network of friends and family. Look at a similar social map today, and you’ll see that the smokers have drifted to the periphery(外围).[M]The better this kind of mapping becomes, the more value it has.[N]Officials at the Centers for Disease Control and Prevention(CDC)are exploiting the connectedness of youngsters in online socialnetworks, for example, to improve flu-vaccination rates, not just among those under age 18 but among all the people to whom these children have ties. “Because of their social and peer networks, children have a higher likelihood of sharing information with the most people,”says Jay Bernhardt of the CDC. By targeting youngsters on these sites with information about the importance of annual flu shots, health officials hope to trigger a literal and figurative viral wave of vaccination among the kids’ peers, their peers’ peers, and even those peers’ parents and grandparents.[O]”We are always looking for exciting new areas of research that will help people live healthier,” says Richard Suzman, director of the division of behavioral and social research at the National Institute on Aging. “Without a doubt, I see this as a very promising area.”And with the health community a web like any other, expect that idea to spread further and further.1.Environmental factors couldn’t explain people’s shared joy, because the spreading of happiness varied among different relationships.正确答案:J解析:根据题干中的explain people’s shared joy,varied将本题出处定位于[J]段第2、3句。

2018年12月英语六级阅读模拟试题及详解答案(二)Questions 56 to 60 are based on the followingpassage.There is a certain inevitability that ebook saleshave now overtaken paperback sales on Amazon’sUS site. Amazon’s Kindle 2 is so light and so cheapthat it’s easy to se e why people have rushed to buyit. Though I’m still not keen on the design of the Kindle, it is a vast improvement on itspredecessor and certainly tolerable. Beyond the device itself, Amazon has done a great jobof rolling out Kindle apps, ensuring that people like me-who have an iPad but not a Kindle-canstill join in the fun. Once you’re into the Kindle ecosystem, Amazon locks you in tightly-just asApple does with its iTunes/ iPod ecosystem. It’s so easy to buy from Amazon’s store and thebooks are so cheap that it’s not worth the effort of going elsewhere.While I remain opposed to Amazon’s DRM (数字版权管理)-indeed, I’m opposed to DRM onany ebooks-I have to admit that the implementation is so smooth that most Kindle userswon’t care at all that their ebooks ca n’t be moved to other devices.The ebook trend is nowhere near peaking. Over the next five years we can expect to seemore and more readers move away from printed books and pick up ebooks instead. But I don’tthink that will mean the death of the printed book.There are some who prefer printed books. They like having shelves filled with books they’veread and books they plan to read; they like the feel of the book in their hands and the differentweights and typefaces and layouts of different titles. In other words, they like the physical formof the book almost as much as the words it contains.I can sympathise with those people. As I wrote earlier this week, my ideal situation would befor publishers to bundle ebooks with printed ones-in much the same way that film studiosbtmdie DVDs with digital copies of films. There’s no reason to think that lovers of printed bookswill change their minds. There will undoubtedly be fewer of them as time goes by because morepeople will grow up with ebooks and spend little time with printed ones. However, just as thereare people who love vinyl records(黑胶唱片), even if they were born well into the CD era, therewill still be a dedicated minority who love physical books.Since there are fewer of these people, that will mean fewer bookshops and higher prices forprinted books but I don’t think the picture is entirely bleak.

六级阅读理解模拟练习附答案六级阅读理解模拟练习1:Recent research has claimed that an excess of positive ions in the air can have an ill effect on peoples 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 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 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.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.earthquake答案:BCDAA六级阅读理解模拟练习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, mens and womens 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 sharechild-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 theirfamilies. 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 womens 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 womens 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 womens roles were easily exchanged in the past.C.Mens roles at home were more firmly fixed than womens.D.Men and womens 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.答案:DCBCB。
英语六级阅读理解练习6篇(附答案)二第一篇Pronouncing a language is a skill. Every normal person is expert in the skill of pronouncing his own language; but few people are even moderately proficient at pronouncing foreign languages. Now there are many reasons for this, some obvious, some perhaps not so obvious. But I suggest that the fundamental reason why people in general do not speak foreign languages very much better than they do is that they fail to grasp the true nature of the problem of learning to pronounce, and consequently never set about tackling it in the right way. Far too many people fail to realize that pronouncing a foreign language is a skill—one that needs careful training of a special kind, and one that cannot be acquired by just leaving it to take care of itself. I think even teachers of language, while recognizing the importance of a good accent, tend to neglect, in their practical teaching, the branch of study concerned with speaking the language. So the first point I want to make is that English pronunciation must be taught; the teacher should be prepared to devote some of the lesson time to this, and should get the student to feel that here is a matter worthy of receiving his close attention. So, there should be occasions when other aspects of English, such as grammar or spelling, are allowed for the moment to take second place.Apart from this question of the time given to pronunciation, there are two other requirements for the teacher: the first, knowledge; the second, technique.It is important that the teacher should be in possession of the necessary information. This can generally be obtained from books. It is possible to get from books some idea of the mechanics of speech, and of what we call general phonetic theory. It is also possible in this way to get a clear mental picture of the relationship between the sounds of different languages, between the speech habits of English people and those, say, of your students. Unless the teacher has such a picture, any comments he may make on his students' pronunciation are unlikely to be of much use, and lesson time spent on pronunciation may well be time wasted.1. What does the writer actually say about pronouncing foreign languages?A. Only a few people are really proficient.B. No one is really an expert in the skill.C. There aren't many people who are even fairly good.D. There are even some people who are moderately proficient.2. The writer argues that going about the problem of pronunciation in the wrong way isA. an obvious cause of not grasping the problem correctlyB. a fundamental consequence of not speaking wellC. a consequence of not grasping the problem correctlyD. not an obvious cause of speaking poorly3. The best way of learning to speak a foreign language, he suggests, is by_______.A. picking it up naturally as a childB. learning from a native speakerC. not concentrating on pronunciation as suchD. undertaking systematic work4. The value the student puts on correct speech habits depends upon_______.A. how closely he attends to the matterB. whether it is English that is being taughtC. his teacher's approach to pronunciationD. the importance normally given to grammar and spelling5. How might the teacher find himself wasting lesson time?A. By spending lesson time on pronunciation.B. By making ill-informed comments upon pronunciation.C. By not using books on phonetics in the classroom.D. By not giving students a clear mental picture of the difference between sounds.第二篇An industrial society, especially one as centralized and concentrated as that of Britain, is heavily dependant on certain essential services: for instance, electricity supply, water, rail and road transport, the harbors. The area of dependency has widened to include removing rubbish, hospital and ambulance services, and, as the economy develops, central computer and information services as well. If any of these services ceases to operate, the whole economic system is in danger.It is this interdependency of the economic system that makes the power of trade unions such an important issue. Single trade unions have the ability to cut off many economic blood supplies. This can happen more easily in Britain than in some other countries, in part because the labor force is highly organized. About 55 per cent of British workers belong to unions, compared to under a quarter in the United States. For historical reasons, Britain's unions have tended to develop along trade and occupational lines, rather than on an industry-by-industry basis, which makes wage policy, democracy in industry and the improvement of procedures for fixing wage levels difficult to achieve.There are considerable strains and tensions in the trade union movement, some of them arising from their outdated and inefficient structure. Some unions have lost many members because of industrial changes. Others are involved in arguments about who should represent workers in new trades. Unions for skilled trades are separate from general unions, which means that different levels of wages for certain jobs areoften a source of bad feeling between unions. In traditional trades which are being pushed out of existence by advancing technologies, unions can fight for their members' disappearing jobs to the point where the jobs of other union's members are threatened or destroyed. The printing of newspapers both in the United States and in Britain has frequently been halted by the efforts of printers to hold on to their traditional highly-paid jobs.1. Why is the question of trade union power important in Britain?A. The economy is very much interdependent.B. Unions have been established a long time.C. There are more unions in Britain than elsewhere.D. There are many essential services.2. Because of their out-of-date organization some unions find it difficult to______.A. change as industries changeB. get new members to join themC. learn new technologiesD. bargain for high enough wages3. Disagreements arise between unions because some of themA. try to win over members of other unionsB. ignore agreementsC. protect their own members at the expense of othersD. take over other union's jobs4. It is difficult to improve the procedures for fixing wage levels because______.A. some industries have no unionsB. unions are not organized according to industriesC. only 55 per cent of workers belong to unionsD. some unions are too powerful5. Which of the following is NOT TRUE?A. There are strains and tensions in the trade union movement.B. Some unions have lost many members.C. Some unions exist in the outdated structure.D. A higher percentage of American workers belong to unions than that of British workers.第三篇Although credit cards are becoming a more acceptable part of the financial scene, they are still regarded with suspicion 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 suchpeople 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 the card 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 potential goldmine 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.1. 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.2. The foolhardy are people who_______.A. spend more money than they haveB. spend less money than other peopleC. save moneyD. make money3. 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 difficulty4. According to the passage, credit cards are made of_______.A. paperB. goldC. plasticD. tin5. Deciding on a particular credit, you do not have to consider______.A. the amount of credit grantedB. the number and range of outletsC. the possibility of loss of moneyD. the department stores where you are going to use your credit cards第四篇More attention was paid to the quality of production in France at the time of Rene Coty. Charles Deschanel was then the financial minister. He stressed that workmanship and quality were more important than quantity for industrial production. It would be necessary to produce quality goods for the international markets tocompete with those produced in other countries. The French economy needed a larger share of international market to balance its import and export trade.French industrial and agricultural production was still inadequate to meet the immediate needs of the people, let alone long-ranged developments. Essential imports had stretched the national credit to the breaking point. Rents were tightly controlled, but the extreme inflation affected general population most severely through the cost of food. Food costs took as much as 80 percent of the worker's income. Wages, it is true, had risen. Extensive family allowances and benefits were paid by the state, and there was fulltime and overtime employment. Taken together, these factors enabled the working class to exist but allowed them no sense of security. In this discouraging situation, workmen were willing to work overseas for higher wages.The government was unwilling to let workers leave the country. It was feared that migration of workers would reduce the labor force. The lack of qualified workers might hinder the improvement in the quality of industrial products produced. Qualified workers employed abroad would only increase the quantity of quality goods produced in foreign countries. Also the quantity of quality goods produced in France would not be able to increase as part of its ualified labor force moved to other countries.1. The purpose of the passage is to_______.A. explain the French government's emphasis on quality productsB. discuss Charles Deschanel's contribution to the French industrial developmentC. compare the quality of French goods with that of foreign goodsD. show French workmen's enthusiasm to seek well-paid jobs in foreign countries2. It can be inferred from the passage that at the time of Rene Coty .A. France was still at the first stage of industrial developmentB. French workers were better paid than the workers in any other European countriesC. the unemployment rate in France was comparatively higher than that in other European countriesD. French workers were able to live better with the increase in their wages3. It is implied in the passage that at that time_______.A. France had a very large share of international marketB. the import and export trade in France was making a successful advanceC. demand and supply in France was barely balancedD. France was experiencing economic depression4. Which of the following is the best indicator of the extreme inflation in France?A. Eighty percent increase in the prices of consumer goods.B. High cost of food.C. High rents for houses.D. Lack of agricultural products.5. Which of the following is NOT mentioned in the passage?A. Rents in France were tightly controlled.B. France was flooding the international market with inferior products.C. French workers were prohibited from going abroad to find jobs.D. The migration of French workers would hinder the improvement of quality in industrial production.第五篇As a company executive(总经理) who spent ten years in federal service, I am often asked what I regard as the biggest difference between working for the government and working for a private company. My invariable response is to say that I look back on my time in government as one of the most exciting and challenging experiences of my life. Furthermore, I never worked as hard as when I was a public servant.When I worked for the government, I worked with some of the finest, most competent and most committed people I have ever met. I was impressed by the overall quality of our career civil servants then, and I still am. But one of my greatest concerns now is that I will not be able to hold this same high opinion in the future.Career public servants are leaving government in alarming numbers, and qualified replacements are becoming harder and harder to find. Good people who leave career government service are striving for highly paid positions in private enterprises.We depend on government to keep this country safe in an uncertain world, to secure justice and domestic order and to solve a host of pressing problems. We need the best possible people performing and overseeing these vital tasks. A high-quality, professional federal service has been a source of national pride for more than a century. But what we have built up during a hundred years can be lost in less time than we imagine. We can't afford to let this happen. We must act now if this country is to be assured of the quality public service it deserves.1. Career public servants are leaving government in alarming numbers. One of thereasons may be that______.A. they received lower payB. they deserved no fame and gloryC. they performed poorlyD. they worked harder than anyone else2. According to the author, _______, so I will not be able to hold this same high opiniontoward the public servants in the future.A. I never worked as hard as when I was a public servantB. I have become a company executiveC. there will not be so many competent and qualified servants in the government as we had beforeD. my time in government was not the most exciting experience in my life3. We depend on government to keep this country safe in an uncertain world, therefore,A. we should make greater contributions to the countryB. the best possible people are urgently needed to do important tasksC. we should show deep concern about the nation's futureD. we should become public servants4. If we neglect the serious problem and make no efforts, we will lose_______.A. national prideB. high-quality professional federal serviceC. good peopleD. private enterprise5. Which of the following is NOT TRUE?A. Those who work for companies are highly paid.B. More and more public servants have left the government.C. Career public servants are qualified.D. Many people of high qualities want to work in the government.According to the latest research in the' United States of America, men and women talk such different languages that it is like people from two different cultures trying to communicate. Professor Deborah Tannen of Georgetown University, has noticed the difference in the style of boy's and girl's conversations from an early age. She says that little girls' conversation is less definite than boys' and expresses more doubts. Little boys use conversation to establish status with their listeners.These differences continue into adult life, she says. In public conversations, men talk most and interrupt other speakers more. In private conversations, men and women speak in equal amounts—although they say things in a different style. Professor Tannen believes that, for woman, private talking is a way to establish and test intimacy. For men, private talking is a way to explore the power structure of a relationship.第六篇Teaching is one job where the differences between men's and women's ways of talking show. When a man teaches a woman, says Professor Tannen, he wants to show that he has more knowledge, and hence more power in conversation. When a woman teaches another woman, however, she is more likely to take a sharing approach and to encourage her student to join in.But Professor Tannen does not believe that women are naturally more helpful. She says women feel they achieve power by being able to help others. Although the research suggests men talk and interrupt people more than women, Professor Tannen says, women actually encourage this to happen because they believe it will lead to more intimacy and help to establish a relationship.Some scientists who are studying speech think that the brain is pre¬programmedfor language. As we are usually taught to speak by women, it seems likely that the brain must have a sexual bias(倾向性) in its programming,otherwise male speech patterns would not arise at all.1. In the opinion of the writer, women encourage men to talk becauseA. it will lead to more intimacy and help to establish a relationshipB. it will help to establish status with their listenersC. it will help to express more clearlyD. it will help to communicate better2. There are_______in little girls' conversation than in boys'.A. fewer doubtsB. more demandsC. more doubtsD. fewer uncertainties3. Some scientists believe that brain is pre-programmed for language. The word "pre programmed" means_______.A. programmed alreadyB. programmed before one is bornC. programmed earlyD. programmed by women4. In private conversation, women speakA. the same things as menB. less than menC. more than menD. as much as men5. The theme of this article is _______.A. women are naturally more helpfulB. men and women talk different languagesC. men talk most and interrupt other speakers moreD. little girls' conversation is less definite第一篇答案、1.

6月英语六级考试阅读模拟题及答案(二)Part II Reading Comprehension (35 minutes)Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage OneQuestions 21 to 25 are based on the following passage.There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the finding of science.Another distinction between science and technology has to do with the progress in each.Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people's likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or anger people-as did Darwin's theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But hardly so with technology; we do not have the choice of refusing to hear the sonic boom produced by a supersonic aircraft flying overhead; we do not have the option of refusing to breathe polluted air; and we do not have the option of living in a non-atomic age. Unlike science progress, technology must be measured in terms of the human factor. The legitimate purpose of technology is to serve people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves. Technology must be humanistic if it is to lead to a better world.21. The difference between science and technology lies in that _____.A) the former provides answers to theoretical questions while the latter to practical problemsB) the former seeks to comprehend the universe while the latter helps changethe material worldC) the former aims to discover the inter-connections of facts and the rules that explain them while the latter, to discover new designs and ways of making the things we use in our daily lifeD) all of the above22.

According to the author, scientific theories _____.A) must be strictly objectiveB) usually take into consideration people's likes and dislikesC) should conform to popular opinionsD) always appear in perfect and finished forms24. The author states that technology itself _____.A) is responsible for widespread pollution and resource exhaustionB) should serve those who wish to gain advantage for themselvesC) will lead to a better world if put to wise useD) will inevitably be for bad purpose25.

You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage OneQuestions 21 to 25 are based on the following passage.Acculturation, which begins at birth, is the process of teaching new generations of children the customs and values of the parents culture. How people treat newborns, for example, can be indicative of cultural values. In the United States it is not uncommon for parents to put a newborn in a separate room that belongs only to the child. This helps to preserve parents privacy and allows the child to get used to having his or her own room, which is seen as a first step toward personal independence. Americans traditionally have held independence and a closely related value, individualism, in high esteem. Parents try to instill theseprevailing values in their children. American English expresses these value preferences: children should cut the (umbilical) cord and are encouraged not to be tied to their mothers apron strings. In the process of their socialization children learn to look out for number one and to stand on their own two feet。

英语六级模拟卷二(附答案)Part ⅡReading Comprehension(35 minutes)Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.Passage OneQuestions 21 to 25 are based on the following passage.Perhaps all criminals should be required to carry cards which read : “F ragile : handle with care.” It will never do, theses days, to go around referring to criminal as violent thugs.You must refer to them politely as “social misfits” ( 不能适应社会的人).The professional killer who wouldn’t think twice about using his club or knife to batter some harmless old lady to death in order to rob her of her meager life savings must never be given a dose of his own medicine. He is in need of “hospital treatment”. According to his misguided defenders, society is to blame.A wicked society breeds evil or so the argument goes. When you listen to this kind of talk, it makes you wonder why we aren’t all criminals. We have done away with the absurdly harsh laws of the nineteenth century and this is only right. But surely enough is enough. The most senseless piece of criminal legislation in Britain and a number of other countries has been the suspension of capital punishment.The violent criminal has become a kind of hero-figure in our time. He is glorified on the screen ; he is pursued by the press and paid vast sum of money for his “memories”. Newspapers which specialize in crime reporting enjoy enormous circulations and the publishers of trashy cops and robbers stories or “murder mysteries” have never had it so good. When you read about the achieveme nts of the great train robbers, it makes you wonder whether you are reading about some glorious resistance movement. The hardened criminal is cuddled and cosseted by the sociologists on the one hand and adored as a hero by the masses on the other. It’s no wonder he is a privileged person who expects and receives VIP treatment wherever he goes.Capital punishment used to be a major deterrent. It made the violent robber think twice before pulling the trigger. It gave the cold blooded poisoner something to ponder about while he was shaking up or serving his arsenic cocktail. It prevented unarmed policemen from being killed while pursuing their duty by killers armed with automatic weapons. Above all, it protected the most vulnerable members of society, young children, from brutal violence.It is horrifying to think that the criminal can literally get away with murder. We all know that “life sentence” does not meanwhat it says. After ten years or so of good conduct, the most desperate villain is free to return to society where he will live very comfortably, thank you, on the proceeds of his crime, or he will go on committing offences until he is caught again. People are always willing to hold liberal views at the expense of others. It’s always fashionable to pose as the defender of the under-dog, so long as you, personally, remain unaffected. Did the defenders of crime, one wonders, in their desire for fair play, consult the victims before they suspended capital punishment? Hardly, you see, they couldn’t, because all the victims were dead.21. According to the passage, which of the following is the author’s opinion?A) All criminals should be required to carry cards read : “Fragile : Handle with Care.”B) Capital punishment is the only way to deter criminals.C) Society is to blame.D) All criminals need hospital treatment.22. The tone taken by the author towards these defenders of crime in the passage is .A) ironicalB) criticalC) agitatedD) controversial23. “Capital punishment” most probably means .A) life sentenceB) severe punishmentC) fineD) sentence of death24. Which of the following is true according to the passage?A) There has been a marked trend in society towards the humane treatment of less fortunate members.B) Everyone in society thinks it reasonable that all criminals should be punished.C) The author sympathizes with all criminals.D) Robbers usually think twice before shooting.25. What conclusion can be drawn from the passage?A) Professional killers should not be treated with humane treatment.B) The violent robbers should think twice before pulling the trigger.C) We should give the poisoner time to ponder about while he is shaking up or serving his arsenic cocktail.D) Severe punishment,even death penalty, should be given to criminals.Passage TwoQuestions 26 to 30 are based on the following passage.For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization. Every dispensable item of contemporary technology, from canal locks to dial telephones to penicillin, was pieced together from the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human interliving, long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go on with it or not. There is an argument.Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets any day these days on the issue of nuclear energy. Give it back, say some of the voices, it doesn’t really work, we’ve tried it and it doesn’t work, go back three hundred years and start again on something else less chancy for the race of man.The principle discoveries in this century, taking all in all, are the glimpses of the depth of our ignorance about nature. Things that used to seem clear and rational, matters of absolute certainty—Newtonian mechanics, for example—have slipped through our fingers, and we are left with a new set of gigantic puzzles, cosmic uncertainties, ambiguities; some of the laws of physics are amended every few years, some are canceled outright, some undergo revised versions of legislative intent as if they were acts of Congress.Just thirty years ago we call it a biological revolution when the fantastic geometry of the DNA molecule was exposed to public view and the linear language of genetics was decoded. For a while, things seemed simple and clear, the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch. But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today’s imagining.It is not just that there is more to do, there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology or the cultivation of nutrients in the sea. As we learn more about fundamental processes of living things in general we will learn more about ourselves.26. What can’t be inferred from the 1st paragraph?A) Scientific experiments in the past three hundred years have produced many valuable items.B) For three hundred years there have been people holding hostile attitude toward science.C) Modern civilization depends on science so man supports scientific progress unanimously.D) Three hundred years is not long enough to settle back critical appraisal of scientific method.27. The principle discovery in this century shows .A) man has overthrown Newton’s laws of physicsB) man has solved a new set of gigantic puzzlesC) man has lost many scientific discoveriesD) man has given up some of the once accepted theories28. Now scientists have found in the past few years .A) the exposure of DNA to the public is unnecessaryB) the tiny cell in DNA is a neat little machineC) man knows nothing about DNAD) man has much to learn about DNA29. The writer’s main purpose in writing the passage is to say that .A) science is just at its beg inning B) science has greatly improved man’s lifeC) science has made profound progress D) science has done too little to human beings30. The writer’s attitude towards science is .A) criticalB) approvingC) neutralD) regretfulPassage ThreeQuestions 31 to 35 are based on the following passage.The desire for achievement is one of life’s great mysteries. Social scientists have devoted lifetimes to studying the drives that spur us out of bed in the morning,compel us to work or study hard and spark all manner of human endeavor.Indeed, a 1992 textbook actually documents 32 distinct theories of human motivation.Given this diversity of thought,it’s easy to forget that for a half century,American society has been dominated by the psychological school known as behaviorism, or Skinnerian psychology. Although behaviorism and its fundamental principle of “positive reinforcement” have long since lost their sway in academic circles, the Skinnerian legacy remains powerful in every realm of trash out. Do it, and you can go to the movies Friday night.Not in the mood for work? Keep plugging away,and you might get a bonus. Not interest in calculus? Strive for an A in the class, and you will make the honor roll. The theory may be bankrupt, but incentives and rew ards are so much a part of American culture that it’s hard to imagine life without them.Yet that’s exactly what a growing group of researchers are advocating today.A steady stream of research has found that rather than encouraging and diminishing perfo rmance, “our society is caught in a whopping paradox,” asserts Alfie Kohn, author of the new book published by Rewards (Houghton Mifflin), which surveys recent research on the effectiveness of rewards. “We complain loudly about declining productivity, the crisis of our school and the distorted values of our children. But the very strategy we use to solve those problems damaging rewards like incentive plans and grade and candy bars in front of people is partly responsible for the fix we’re in.”It’s a tough argument to make in a culture that celebrates the spoils of success. Yet study after study shows that people tend to perform worse, to give up more easily and to lose interest more quickly when a reward is involved. Children who are given tr eats for doing artwork, for example, lose for tutoring youngsters don’t teach as enthusiastically as tutors offered nothing. And chief executive officers who have been awarded long term incentive plans have often steered their companies toward lower returns.31.According to behaviorism, all human actions .A) are based on stimulus and responseB) have no bearing on human drivesC) are supposed to be highly motivatedD) are of a great mystery32.Behaviorism basically believes in .A) motivationB) performanceC) rewardsD) human factors33. From the passage, it can be inferred that .A) rewards are highly effective in AmericaB) rewards are not much sought after in academic circlesC) rewards have long lost their appeal in American societyD) Americans are addicted to rewards34. The children’s behavior in the last paragraph .A) can be best explained be behaviorismB) can be linked to Pavlov’s dogsC) shows that rewards may well kill desireD) serve to provided evidence to behaviorism35. Which of the following in support of the finding that “people tend to perform worse,…when a reward is involved”( last paragraph )?A) People are not used to being conditioned by prizes.B) Rewards, like punishments, are attempts to control behavior.C) Rewards are so indispensable to American cultures.D) The principle of “positive reinforcement” in not fully enforced.Passage FourQuestions 36 to 40 are based on the following passage.In general, our society is becoming one of giant enterprises directed by a bureaucratic (官僚主义的) management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, well-ventilated factories and piped music, and by psychologists and “human-relations” experts; yet all this oiling does not alter the fact that man has become power-less, that he does not wholeheartedly participate in his work and that he is bored with it. In fact, theblue and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management.The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction or interest in life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings.Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self respect. When they apply for their first job, they are tested for intelligence as well as for the tight mixture of submissiveness and independence. From that moment on they are tested again and again by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one’s fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness.Am I suggesting that we should return to the preindustrial mode of production or to nineteenth-century “free enterprise capitalism”? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social from a bureaucratically managed industrialism in which maximal production and consumption are ends in themselves into a humanist industrialism in which man and full development of his potentialities—those of and of reason—are the aims of all social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.36. By “a well-oiled cog in the machinery” the author intends to render the idea that man is .A) a necessary part of the society though each individual s function is negligibleB) working in complete harmony with the rest of the societyC) an unimportant part in comparison with the rest of the society, though functioning smoothlyD) a humble component of the society, especially when working smoothly37. The real cause of the anxiety of the workers and employees is that .A) they are likely to lose their jobsB) they have no genuine satisfaction or interest in lifeC) they are faced with the fundamental realities of human existenceD) they are deprived of their individuality and independence38. From the passage we can infer that real happiness of life belongs to those .A) who are at the bottom of the societyB) who are higher up in their social statusC) who prove better than their fellow-competitorsD) who could keep far away from this competitive world39. To solve the present social problems the author suggests that we should .A) resort to the production mode of our ancestorsB) offer higher wages to the workers and employeesC) enable man to fully develop his potentialitiesD) take the fundamental realities for granted40. The author’s attitude towards industrialism might best be summarized as one of .A) approval B) dissatisfaction C) suspicion D) tolerancePart ⅢVocabulary (20 minutes)Directions: There are 30 incomplete sentences in this part.

Whether the realityof life in the family house is sweet or no sweet. The S1cherished ideal of home has great importance for manypeople.This ideal is a vital part of the American dream. Thisdream, dramatized in the history of nineteenth-centuryEuropean settlers of the American west, was to finda piece of place, build a house for one’s family, and S2started a farm. These small households were portraits of S3independence : the entire family—mother, father, and children.Even grandparents—live in a small house and working S4together to support each other. Anyone understood the life S5and death importance of family corporation and hard work.Although most people in the United states no longerlive on farms, but the ideal of home ownership is just as S6strong in the twentieth century, as it was in the nineteenth.When U.S. soldiers came home before World War II for S7example, they dreamed of buying houses and startingfamilies. But there was a tremendous boom in the home S8building. The new house, typically in the suburbs,wereoften small and more or less identical, but it satisfied S9a deep need. Many regarded the single-familyhouse the basis of their way of life.

大学英语六级模拟考试卷及答案(3)PartⅡReading Comprehension(35minutes)Directions:There are four passages in this part.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.Questions21to23are based on the following passage:The Caledonian Market in London is a clearing house of the junk(旧货、废弃物)of the universe. Here,rubbish is a commodity and rubbish picking is a sport.Somebody,somewhere,wanted these things,perhaps just to look at.You learn here the incredible obscurity of human needs and desires. People grope(摸索),with fascinated curiosity,among the turned out debris(废墟)of thousands of attic rooms.Junk pours in twice a week,year in and year out.The Market is the penultimate (倒数第二的)resting place of banished vases,musical instruments that will not play,sewing machines that will not sew,paralyzed perambulator,epileptic bicycles and numerous other articles from which all morale and hope have long departed.There are stories of fortunes being picked up in the Market.Once seven hundred gold sovereigns were found in a secret drawer of a crazy old bureau.And book buyers have discovered valuable editions of Milton and Dickens and Carlyla. There is nothing one can not buy in the Market.21.The title below that best expresses the idea of this passage is____.A)Why People Buy What They DoB)Reflections on A Famous Junk MarketC)The Cause for Fascinated CuriosityD)What Happens to Attic Debris22.The articles for sale in the Caledonian Market____.A)are wanted to look atB)are collected100times a yearC)reveal obscure needs and desiresD)bring fortune to the buyers23.From the style of this passage one might assume that it was taken from____.A)a report on marketingB)a guide bookC)directions for a stage settingD)an information essayQuestions24to30are based on the following passage:Allelomimetic behavior may be defined as behavior in which two or more individual animals do the same thing,with some degree of mutual simulation and coordination.It can only involve in species with sense organs that are well enough developed so that continuous sensory contact can be maintained.It is found primarily in vertebrates(脊椎动物),in those species that are diurnal, and usually in those that spend much of their lives in the air,in open water or on open plains. In birds,allelomimetic behavior is the rule rather than the exception,though it may occasionally be limited to particular seasons of the year as it is in the redwing blackbird.Its principal function is that of providing safety from predators(掠食者),partly because the flock can rely on many pairs of eyes to watch for enemies,and partly because if one bird reacts to danger,the whole flock is warned.Among mammals,allelomimetic behavior is very rare in rodents(啮齿动物), which almost never move in flocks or herds.Even when they are artificially crowded together, they do not conform in their movements.On the other hand,such behavior is a major system among large hoofed mammals,such as sheep.In the pack hunting carnivores(食肉类飞禽),allelomimetic behavior has another function of cooperative hunting for large prey(被捕食者)animals,such as moose.Wolves also defend their dens as a group against larger predators,such as bears.Finally, allelomimetic behavior is highly developed among most primate groups,where it has the principal function of providing warning against predators,as though combined defensive behavior is also seen in troops of baboons(狒狒).24.The main topic of the passage is the____.A)value of allelomimetic behavior in vertebrate and invertebrate speciesB)definition and distribution of allelomimetic behaviorC)relationship of allelomimetic behavior to the survival of the fittest D)personality factors that determine when an individual animal will show allelomimetic behavior25.Which of the following places is the most likely setting for allelomimetic behavior?A)A lake.B)A cave.C)An underground tunnel.D)A thick forest.26.The author implies that allelomimetic behavior occurs most often among a nimals that____.A)prey on other animalsB)are less intelligent than their enemiesC)move in groupsD)have one sense organ that dominates perception27.Which of the following is the most clear example of allelomimetic?A)Bears hunting for carnivores.B)Cattle fleeing from a fire.C)Horses running at a racetrack.D)Dogs working with police officers.28.According to the passage the primary function of allelomimetic behavior in bird is to____.A)defend nests against predatorsB)look at each otherC)locate preyD)warn against predators29.According to the passage,what happens to the behavior of rodents when they are artificially crowded together?A)Their allelomimetic behavior increases.B)Continuous cooperation between them is maintained.C)They become aggressive and attack each other.D)They show little allelomimetic behavior.30.Which of the following groups of human beings would probably show the greatest amount of allelomimetic behavior?A)A group of students taking a test.B)Tennis players competing in a tournament.C)A patrol of soldiers scouting for the enemy.D)Drivers waiting for a traffic light to change.Questions31to35are based on the following passage:The American Heart Association and other groups have said for many years that people could reduce the chance of suffering a heart attack by eating less of the foods rich in cholesterol(胆固醇). These include such foods as meats,milk products and eggs.The Heart Association noted a number of studies which show that nations where people eat a lot of high cholesterol foods have a higher number of deaths from heart disease.However,the new report disagrees.It was made by the Food and Nutrition Board of the United States National Academy of Sciences.The new report by a team of15scientists said there is no evidence to link cholesterol in food directly to heart disease. It noted seven major studies involving people whose diet was changed to include only foods low in cholesterol.The studies found only a very small reduction in the number of heart attacks and there was no reduction in the number of heart attack deaths.Other studies have shown similar results.They found that a change to low cholesterol foods will have only a minor effect on the amount of cholesterol in a person's blood and only a minor effect on the number of deaths.Medical scientists hope that two huge new studies may settle the cholesterol dispute.The tests are designed to learn if low cholesterol foods or anticholesterol drugs,or both,can reduce the amount of the substance in the blood and reduce the chance of a heart attack.The two new studies will be finished in the next year or two.The new Academy of Sciences report also discussed other possible links between food and disease.The scientists,in general,they are deeply concerned about some of the recent advice given about food.They noted that a number of private groups,government agencies and several popular books have advised that people can prevent heart disease,cancer and other sicknesses by changing the kinds of foods they eat.The new report said there is often no good scientific evidence to support such advice.In fact,the scientists said such ideas often produce only false hopes or unnecessary fears.31.According to the passage,people could reduce the chance of suffering he art attack by____.A)eating less foods with a lot of cholesterolB)eating less of low cholesterol foodsC)eating a lot of high cholesterol foodsD)eating drugs32.High cholesterol foods include____.A)eggs,meats and milk productsB)potatoes,green vegetables and tomatoesC)corn,wheat and beefD)sugar,rice and butter33.Some scientists believe that there is no evidence that cholestrol in food is directly linked to____.A)blood diseaseB)heart diseaseC)infectious diseaseD)mental disorder34.Medical scientists believe that____.A)tests have been designed to settle the cholesterol disputeB)drugs have been tested to reduce the amount of the substance in bloodC)low cholesterol foods or anti cholesterol drugs or both can reduce the chance of a heart attackD)none of the statements mentioned above is correct35.Which of the following statements in NOT true?A)One can avoid a heart disease by eating less foods with little cholesterol.B)One can avoid a heart disease by taking the doctor's advice to eat low cholesterol foods and anti cholesterol drugs or both.C)There has been good scientific evidence that cholesterol foods can produce the chance of suffering a heart disease.D)People usually believe that cholesterol foods are directly linked to heart disease.Questions36to40are based on the following passage:The most interesting architectural phenomenon of the1970's was the enthusiasm for refurbishing old buildings.Obviously,this was not an entirely new phenomenon.What is new is the wholesale interest in reusing the past,in recycling,in adaptive rehabilitation.A few trial efforts,such as Ghirardelli Square in San Francisco,proved their financial viability in the1960's,but it was in the1970's,with strong government support through tax incentives and rapid depreciation, as well as growing interest in ecology issues,that recycling became a major factor on the urban scene.One of the most comprehensive ventures was the restoration and transformation of Boston's eighteenth century Faneuil Hall and the Quincy Market,designed in1824.This section had fallen on hard times,but beginning with the construction of a new city hall immediately adjacent,it has returned to life with the intelligent reuse of these fine old buildings under the design leadership of Benjamin Thompson.He has provided a marvelous setting for dining,shopping, professional offices,and simply walking.Butler Square,in Minneapolis,examplifies major changes in its complex of offices,commercial space,and public amenities carved out of a massive pile designed in1906as a hardware warehouse.The exciting interior timber structure of the building was highlighted by cutting light courts through the interior and adding large skylights.San Antonio,Texas,offers an object lesson for numerous other cities combating urban decay.Rather than bringing in the bulldozers,San Antonio's leaders rehabilitated existing structures,while simultaneously cleaning up the San Antonio River,which meanders through the business district.36.What is the main idea of the passage?A)During the1970's,old buildings in many cities were recycled for modern use.B)Recent interest in ecology issues has led to the cleaning up of many rivers.C)The San Antonio example shows that bulldozers are not the way to fight u rban decay.D)Strong government support has made adaptive rehabilitation a reality in Boston.37.What is the space at Quincy Market now used for?A)Boston's new city hall.B)Sports and recreational facilities.C)Commercial and industrial warehouses.D)Restaurants,offices,and stores.38.According to the passage,Benjamin Thompson was the designer for a proje ct in____.A)San FranciscoB)BostonC)MinneapolisD)San Antonio39.When was the Butler Square building originally built?A)In the eighteenth century.B)In the early nineteenth century.C)In the late nineteenth century.D)In

Despite of these two disadvantages,there is a stronger argument in favor of living with Americans. By living in an American home,the student has an opportunity to become familiar with American customs and culture.For instance,he will learn the importance of family closeness.He can see how the children communicate with their parents and how the parents educate their children.He will not feel like a stranger because the American family will help him adjusting to a new life. In an American home,he can learn English fast.Family members can help him with his homeworks. When he speaks English,they can point out his errors.In this way,he can learn English naturally. Although there are some disadvantage to live with an American family,there are heavier benefits. If the foreign student at first realizes the value of learning about a new culture and improving his English at the same time,he will find studying there a very big experience.PartⅤWriting(30minutes)Directions:For this part,you are allowed thirty minutes to write a composition on the topic “The1998Summer Flood”.You should write at least150words and you should base your composition on the outline(given in Chinese)below:答案PartⅡ21.答案B。
2021年6月英语六级阅读理解模拟题附答案(2)Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this passage, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1.How to Buy a Used CarNearly everybody buys a used car sooner or later, as a primary vehicle or as a second car. Indeed, three out of four sales today are used cars, and they're not cheap junkers either —the average price now is $ 5500, about half what a new car costs. Make the wrong selection and a major investment can be lost the moment you drive off the lot.There is far less chance of this happening to you if you know: when to buy, where to buy, how to examine the car, how to conduct your own road test, and how to bargain over the price.When to buyShop during the day. Lighting makes cars gleam like jewels at night. In daylight they look dull, but realistic.Don't shop in the rain. It can mask liquids that might be leaking. If possible, shop in the winter when supplies are highand demand is low.Where to buyShop the suburbs. In more affluent neighbourhoods cars are more likely to have been well cared for.A private owner normally sells a car for less than a dealer does, but almost always "as is," with no guarantee. That's an acceptable risk if what you're looking for is a cheap second car to "drive to the station. "Even though a used-car dealer generally charges more, you can often get some type of limited guarantee. This is often a 50-50 plan, in which you each pay half on repairs for a period that may range from 30 days to a year. Ask the dealer about the availability of an optional service policy.Used-car dealers often claim to have gone over the car, and many have. But remember that small dealers often buy cars that are auctioned (拍卖 ) because nobody else wants them.Some experts feel that a new-car dealer is the best place to buy a secondhand car, especially if you're laying out a large sum for a late model. Some of these dealers offer extensive guarantees, such as one on the "drive train," which covers any problems with engine, transmission(变速器) , drive shaft and differential (差速器 ). Expect to pay for this, as well as forthe markup. But if you shop soon after the new models have arrived, when a dealer has a lot of trade-ins tying up his profits, he might deal. The visual examinationYou've found your dream car, and can hardly wait to get in and roar away. Wait.First, look for any flaws or ripples(划痕) in the body that might indicate a past accident. To see if a car has been repainted, look under the rubber seals around the door or under the chrome trim. Repainting may mask deep flaws.Check the odometer (计程器) for total mileage, and then compare that figure with any stickers still attached to door posts. It's illegal to change odometer readings, but it happens. If there are no stickers, be a little suspicious. Check pedals and controls: wear on these parts should agree with the mileage. If they are brand new, be suspicious. If they are worn out, beware.Check that the doors, hood and trunk all open smoothly and close with solid sound. Sight along the sides of the car from 30 feet away to be sure that the rear and front wheels line up.Look under the car for fluid leaks. Except for condensation from a working air conditioner on a hot day, no car should ever drip anything, any time.Now sit in the driver's seat and try the controls. The car should fit you—it should be comfortable. Check seat adjustment, door locks, window-raising mechanisms, horn, lights, directional signals, radio—all accessories.Start the engine. It should turn over quickly and then settle down to a rather fast idle. Give the engine a moment or two before you press the accelerator a bit. Watch for smoke from the rear. Blue smoke might mean a complete engine overhaul (大修) , black a maladjusted carburettor (化油器). ? 2 ?White smoke can be.ignored if the engine is cold, but once it is warmed up, white smoke can mean a leaking head gasket (垫圈) : expensive. Reject this car.After the engine has warmed, shut it off, and then go wipe your finger inside the tailpipe (making sure it's not too hot). The residue should be whitish-gay. If you get a black, oily mark, refuse the car—it's probably an oil burner.Restart the engine and check the oil in an automatic transmission. It should be clean and clear, with no burned odor. The test driveThe salesman may try to convince you that a short drive around the block is enough. Wrong. Make it clear that you plan to road test the car, and if he isn't happy with this lookelsewhere.The test route you have mapped out should include dry city streets, a freeway, a hill, a bumpy road and an empty parking lot. All gauges(计量器) should read steady and normal throughout the test, especially oil pressure and engine heat. If not, don't buy the car.Drive to a traffic-free city street on your predetermined route and then accelerate smoothly to about 35 miles per hour. The automatic transmission should shift without jerking and with no noise.Slow to about 7 m. p. h. by gently applying the brakes. There should be no noise, no sharp sound or grinding. The car should slow in a straight line, with no pulling to the right or left.Pick up speed to about 15; then making certain nobody is behind you, hit the brakes hard! The car should come to an immediate stop without making noise or swerving.In an empty, level parking lot, brake to a complete stop. Shift into reverse and back up at about 4 m. p. h. , brake to a halt, shift into forward, etc. Do this four or five times to test the transmission. All shifting should be smooth, with no noise or hesitation.Accelerate up a hill to about 40 m. p. h. The car shouldnot labour. If it does, you could have a rotten transmission. Go back down the hill. Stop halfway, shift into neutral and set the parking brake. The car should remain stationary when you take your foot off the brake pedal.Drive the car over the bumpy road, up a hill, and on the highway. Rarely will a car be perfect. However by now you should have a pretty good idea what needs to be done. How to bargain Use what you've learned from the visual exam, test drive and outside mechanic to get the price down. Have a maximum figure in mind, based on your inspection and on current prices from a used-car guide. Start your bidding lower than that. When you have nearly arrived at a price, get the seller to throw in certain repairs. It may be cheaper for him than further price cuts.1. Following the instructions here will help you make a good selection when buying a used car.2. Winter is a good time for purchasing a car because there is little rain in winter.3. You are more likely to pay less to a private owner fora car of poor quality.4. Refuse the car if you find any signs of a past accident in the visual examination.5. Don't buy the car if there is white smoke coming out of the rear because it is probably an oil burner.6. At certain speeds in the tests, a good car should not make any noise when the driver brakes either hard or gently.7. If you are patient and careful enough, you will certainly find a perfect used car.8. The last step before you make a decision to buy a car is______.9. Besides all gauges, the two very important systems mainly examined in the test drive are______.10. According to some experts, the best place to buy a second-hand car is______.参考答案:I. Y 2. N 3. Y 4. NG 5. N 6. Y 7. N8. to bargain over the price 9. brake and transmission 10.a new-car dealer。

Today, tropical rainforests cover only 6 percent of the Earth’s ground surface,but they are home to over half of the planet’s plant and animal species.What Is a Rainforest?Generally speaking,a rainforest is an receives high rainfall and is dominated by tall trees. A wide range of ecosystems fall into this category, of course. But most of the time when people talk about rainforests, they mean the tropical rainforests located near the equator.These forests receive between 160 and 400 inches of rain per year. The total annual rainfall is spread pretty evenly throughout the year, and the temperature rarely dips below 60 degrees Fahrenheit.This steady climate is due to the position of rainforests on the globe. Because of the orientation of the Earth’s axis, the Northern and Southern hemispheres each spend part of the year tilted away from the sun. Since rainforests are at the middle of the globe, located near the equator, they are not especially affected by this change. They receive nearly the same amount of sunlight,and therefore heat, all year. Consequently, the weather remains fairly constant.The consistently wet, warm weather and ample sunlight give plant life everything it needs to thrive. Trees have the resources to grow to tremendous heights. and they live for hundreds, even thousands, of years. These giants,which reach 60 to 150 ft in the air, form the basic structure of the rainforest. Their top branches spread wide in order to capture maximum sunlight. This creates a thick canopy(树冠)level at the top of the forest, with thinner greenery levels underneath. Some large trees grow so tall that they even tower over the canopy layer.As you go lower, down into the rainforest, you find less and less greenery. The forest floor is made up of moss,fungi,and decaying plant matter that has fallen from the upper layers. The reason for this decrease in greenery is very simple:The overabundance of plants gathering sunlight at the top of the forest blocks most sunlight from reaching the bottom of the forest,making it difficult for robust plants to thrive.The Forest for the TreesThe ample sunlight and extremely wet climate of many tropical areas encourage the growth of towering trees with wide canopies. This thick top layer of the rainforest dictates the lives of all other plants in the forest. New tree seedlings rarely survive to make it to the top unless some older trees die, creating a“hole”in the canopy. When this happens,all of the seedlings on the ground level compete intensely to reach the sunlight.Many plant species reach the top of the forest by climbing the tall trees. It is much easier to ascend this way, because the plant doesn’t have to form its own supportingstructure.Some plant species,called epiphytes, grow directly on the surface of the giant trees. These plants,which include a variety of orchids and ferns,make up much of the understory, the layer of the rainforest right below the canopy. Epiphytes are close enough to the top to receive adequate light,and the runoff from the canopy layer provides all the water and nutrients(养分)they need, which is important since they don’t have access to the nutrients in the ground.Stranglers and ButtressesSome epiphytes eventually develop into stranglers. They grow long, thick roots that extend down the tree trunk into the ground. As they continue to grow, the roots form a sort of web structure all around the tree. At the same time, the strangler plant’s branches extend upward,spreading out into the canopy. Eventually, the strangler may block so much light from above,and absorb such a high percentage of nutrients from the ground below, that the host tree dies.Competition over nutrients is almost as intense as competition for light. The excessive rainfall rapidly dissolves nutrients in the soil, making it relatively infertile except at the top layers. For this reason,rainforest tree roots grow outward to cover a wider area, rather than downward to lower levels. This makes rainforest trees somewhat unstable, since they don’t have very strong anchors in the ground. Some trees compensate for this by growing natural buttresses. These buttresses are basically tree trunks that extend out from the side of the tree and down to the ground, giving the tree additional support.Rainforest trees are dependent on bacteria that are continually producing nutrients in the ground. Rainforest bacteria and trees have a very close,symbiotic(共生的) relationship. The trees provide the bacteria with food, in the form of fallen leaves and other material, and the bacteria break this material down into the nutrients that the trees need to survive.One of the most remarkable things about rainforest plant life is its diversity. The temperate rainforests of the Pacific Northwest are mainly composed of a dozen or so tree species. A tropical rainforest, on the other hand, might have 300 distinct tree species.All Creatures, Great and SmallRainforests are home to the majority of animal species in the world. And a great number of species who now live in other environments, including humans, originally inhabited the rainforests. Researchers estimate that in a large rainforest area, there may be more than 10 million different animal species.Most of these species have adapted for life in the upper levels of the rainforest, where food is most plentiful. Insects, which can easily climb or fly from tree to tree, make up the largest group(ants are the most abundant animal in the rainforest).Insect species have a highly symbiotic relationship with the plant life in a rainforest. The insects move from plant to plant, enjoying the wealth of food provided there. As they travel, the insects may pick up the plants’ seeds, dropping them some distance away. This helps to disperse the population of the plant species over a larger area. The numerous birds of the rainforest also play a major part in seed dispersal. Whenthey eat fruit from a plant, the seeds pass through their digestive system. By the time they excrete(排泄)the seeds, the birds may have flown many miles away from the fruit-bearing tree.There are also a large number of reptiles and mammals in the rainforest. Since the weather is so hot and humid during the day, most rainforest mammals are active only at night,dusk or dawn. The many rainforest bat species are especially well adapted for this lifestyle. Using their sonar, bats navigate easily through the mass of trees in the rainforest, feeding on insects and fruit.While most rainforest species spend their lives in the trees,there is also a lot of life on the forest floor. Great apes, wild pigs, big cats and even elephants can all be found in rainforests. There are a number of people who live in the rainforests, as well. These tribes—which, up until recently, numbered in the thousands—are being forced out of the rainforests at an alarming rate because of deforestation.DeforestationIn the past hundred years,humans have begun destroying rainforests at an alarming rate. Today, roughly 1.5 acres of rainforest are destroyed every second. People are cutting down the rainforests in pursuit of three major resources:Land for crops?Lumber for paper and other wood products?Land for livestock pastures?In the current economy, people obviously have a need for all of these resources. But almost all experts agree that, over time, we will suffer much more from the destruction of the rainforests than we will benefit.The world’s rainforests are an extremely valuable natural resource,to be sure, but not for their lumber or their land. They are the main cradle of life on Earth,and they hold millions of unique life forms that we have yet to discover. Destroying the rainforests is comparable to destroying an unknown planet—we have no idea what we’re losing. If deforestation continues at its current rate,the world’s tropical rainforests will be wiped out within 40 years.1. Virtually all plant and animal species on Earth can be found in tropical rainforests.2. There is not much change in the weather in the tropical rainforests all the year round.3.
