英语四级阅读理解精选练习及答案
英语四级阅读理解精选练习及答案英语四级阅读理解练习一:Personality is , to large extent, inherent --A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is improtant to the parents, it is likely to become a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences:remember that Pheidippides ,the first marathon runner, dropped dead seconds after saying:"Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations . It is a rare school that allows pupils to concentrate on those things they do well.The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into Bs. The would needs types, and schools have an important dutyto try to fit a childs personality to his possible future employment. It is top management.1.

Indeed(当然), three out of four sales today are used cars, and theyre not cheap junkers (废物)either—the average price now is $ 5500, about half what a new car costs. Make the wrong selection and a major investment (投资)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 (仔细检查) the car, how to conduct (进行) your own road test, and how to bargain over (讲价)the price.When to buyShop during the day. Lighting makes cars gleam (V 闪光)like jewels (宝石)at night. In daylight they look dull (黯淡的), but realistic.Dont shop in the rain. It can mask(掩盖) liquids (液体) that might be leaking (泄漏). If possible, shop in the winter when supplies are high and demand (需求)is low.Where to buyShop the suburbs. In more affluent (富有的)neighborhoods cars are more likely to have been well cared for.A private owner normally sells a car for less than a dealer(商人) does, but almost always "as is," with no guarantee(质量保证). Thats an acceptable risk if what youre 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 (一段时间)that may range from 30 days to a year. Ask the dealer about the availability of an optional(可选择的) service policy.Used-car dealers often claim (声称)to have gone over (仔细查看)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 youre laying out a large sum (一笔金钱) for a late model. Some of these dealers offer extensive (广阔的)guarantees, such as one on the "drive train," which covers any problems with engine (发动机), transmission(变速器) , drive shaft and differential (差速器 ). Expect to pay for this, as well as for the markup (标高的价格). 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 examination (视觉上的检查)Youve found your dream car, and can hardly wait to get in and roar away. Wait.First, look for any flaws (瑕疵)or ripples(划痕) in the body that might indicate a past accident (暗示曾经出过事故). To see if a car has been repainted(重新漆过), look under the rubber seals around the door or under the chrome trim. Repainting may mask deep flaws (重新上漆可能隐藏深层的瑕疵).Check the odometer (计程器) for total mileage (英里数), and then compare that figure (数字)with any stickers still attached to door posts. Its 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 drivers 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 mightmean a complete engine overhaul (大修) , black a maladjusted carburetor (化油器). 2White 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 its not too hot). The residue should be whitish-gay. If you get a black, oily mark, refuse the car—its 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 drive The 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 isnt happy with this look elsewhere.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, dont 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 should not labor. 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 bargainUse what youve 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 for a car of poor quality.4. Refuse the car if you find any signs of a past accident in the visual examination.5. Dont 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______.答案:1. Y 2. N 3. Y 4. NG 5. N 6. Y 7. N 8. to bargain over the price 9. brake and transmission 10. a new-car dealer。
4级24篇阅读模拟题及答案
一.Baekeland and Hartmann report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.In general, these “short sleeps” appeared ambitious, active, energetic, cheerful, conformist(不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear “normal” or “acceptable” to their friends and associates.When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.The sleep patterns of the “short sleepers” were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic(疯人).The “long sleepers” were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the “short sleepers.”Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep wasan escape from their daily problems.1. According to the report,______.A) many short sleepers need less sleep by natureB) many short sleepers are obliged to reduce their nightly sleep time because they are busy with their workC) long sleepers sleep a longer period of time during the dayD) many long sleepers preserve their sleeping habit formed during their childhood2. Many “short sleepers” are likely to hold the view that _____.A) sleep is a withdrawal from the realityB) sleep interferes with their sound judgementC) sleep is the least expensive item on their routine programD) sleep is the best way to deal with psychological troubles3. It is stated in the third paragraph that short sleepers _____.A) are ideally vigorous even under the pressures of lifeB) often neglect the consequences of inadequate sleepC) do not know how to relax properlyD) are more unlikely to run into mental problems4. When sometimes they cannot enjoy adequate sleep, the long sleepers might ____.A) appear disturbedB) become energeticC) feel dissatisfiedD) be extremely depressed5. Which of the following is Not included in the passage?A) If one sleeps inadequately, his performance suffers and his memory is weakenedB) The sleep patterns of short sleepers are exactly the sane as those shown by many mental patientsC) Long and short sleepers differ in their attitudes towards sleepD) Short sleepers would be better off with more rest答案:DCBAB贝克尔和哈特曼报道说,“睡眠少的人”在未进入少年期之前,其正常睡眠时间大致与所需要的时间差不多。
专业英语四级(阅读)模拟试卷120(题后含答案及解析)
专业英语四级(阅读)模拟试卷120(题后含答案及解析)题型有:1. 2.SECTION AIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked [A], [B], [C] and [D]. Choose the one that you think is the best answer.(1)Job stress and worrying about job security can both take a toll on a woman’s body, although the two issues affect female health differently, according to research presented last month at the American Heart Association’s Annual Meeting in Chicago. But whether chronic work-related stress is eating at your nerves or ballooning your waistline, there are natural solutions with no toxic side effects that you can use to relax the pressure. (2)In a recent study looking at work stress and women, researchers from Harvard and Brigham and Women’s Hospital studied more than 17,000 otherwise healthy women, generally in their 50s, enrolled in the Women’s Health Study for 10 years. Women who reported work-related strain, such as having little or no authority over decisions or being unable to contribute creativity and skills to the job, were up to 88 percent more likely to experience a heart attack than women who reported no work strain. Overall, working women reporting high job strain faced a 40 percent higher rate of cardiovascular(心血管的)disease, too. (3)Worrying about losing a job did not appear to increase heart attack risk, but it was linked to obesity, high blood pressure, and high cholesterol(胆固醇), all of which can eventually lead to cardiovascular disease. (4)Whether it’s a nightmarish cubicle neighbor, an unrelenting workload, or an ornery boss that has your stress meter ready to pop at any second, you can get a grip: It’s all about mind over matter. An August study published in the Proceedings of the National Academy of Sciences found that students taking part in Integrative Body-Mind Training(IBMT)enjoyed changes in white brain matter(within 11 hours of practice)that seemed connected to better regulation of emotions and behavior. (5)Although not very common in the U.S. yet, IBMT involves the practice of maintaining a state of restful alertness to tap into body-mind awareness while a trained coach guides your breathing and mental imagery. It’s somewhat similar to more widely available mindfulness based stress reduction(MBSR), which involves focusing on your present-moment draughts and feelings in a non-judgmental way. MBSR has been shown to help people make clearer decisions in times of crisis, which could help when all health breaks loose at the office.(6)Previous research out of the University of Oregon has found that you could adopt stress-zapping properties of Integrative Body-Mind Training(IBMT)before the workweek’s out. After practicing it for 20 minutes a day for five days in a row, participants reported reduced stress and increased energy. Prevention suggests this intro IBMT exercise: Sit quietly in a comfortable position. Close your eyes and think of your mind as a full cup; as thoughts come and go, keep returning to an image of the cup becoming empty. Repeat for five minutes. (7)Regardless of your meditationstyle, know this: Compared to non-meditators, women who practice meditation enjoy up to a 66 percent drop in stress hormone levels, which can dramatically improve heart health. (8)If you’re in need of an emergency quick freak-out fix, reach for a piece of gum.(Avoid artificial sweetened gum, though—some are linked to health issues.)One study found that chewing gum boosts blood flow to the brain by up to 40 percent, helping you stay calm and in the present. This prevents you from pondering over some aggravating office event. (9)You don’t need to be a monk to enjoy the benefits of meditation. In fact, more and more Western integrative medicine practitioners are using it as a nontoxic health improver.1.According to the passage, which of the following can probably lead to women’s work-related strain?A.They are not creative enough in their work.B.They could not afford to lose their job.C.They have no say in decision-making.D.They are underpaid compared with men.正确答案:C解析:根据work—related strain定位到第2段。

英语四级阅读理解模拟试题及答案Our quarrel with efficiency is not that it gets things done,but that it is a thief of time when it leaves us no leisure to enjoy ourselves, and that it strains our nerves when we try toget things done perfectly. In building bridges, American engineers calculate so finely and exactly as to make the twoends come together within one-tenth of an inch. But when twoChinese begin to dig a tunnel from both sides of a mountainboth come out on the other side. --The Chinese’s firm belief is that it doesn ’t matter so long as a tunnel is dug through, and ifwe have two instead of one, why, we have a double track toboot.The pace of modern industrial life forbids this kind of glorious and magnificent idling. But, worse than that, it imposes upon us a different conception of time as measuredby the clock and eventually turns the human being into a clock himself. (This sort of thing is bound to come to China, as is evident, for instance, in the case of a factory of twenty thousand worker. The luxurious prospect of twenty thousandworkers coming in at their own sweet pleasure at all hours is,of course, somewhat terrifying.)Nevertheless, such efficiency iswhat makes life so hard and full of excitement. A man who hasto be punctually at a certain place at five o ’clock has the whole afternoon from one to five ruined for him already. Every American adult is arranging his time on the pattern of the schoolboy - three o ’clock for this, five o ’ clock for that, six-thirty for change of dress, six-fifty for entering the taxi, andseven o ’clock for arriving at the destination. It just makes lifenot worth living.1.The writer objects to efficiency mainly on thegrounds that it ____.A) entitles us to too much leisure time B)urges us to get things done punctually C)deprives us of leisure timeD) imposes on us a perfect concept of time2.In the eyes of the author, the introduction ofindustrial life gives rise to ____.A) the excitement of lifeB) magnificent idling of timeC) more emphasis on efficiencyD) terrifying schoolboy3.The passage tells us ____.A)Chinese workers come to work when it is convenientB)all Americans are forced to be efficient against their willC)Chinese engineers are on better terms with the managementD)Americans ought not to work so hard for efficiency4.The author believes that relaxing the rule ofpunctuality in factories would lead to ____.A) great confusionB) increased production C)a hard and exciting lifeD) successful completion of a tunnel5.What is implied but NOT stated by the author is that____.A) every American is arranging his time in the pattern of a schoolboyB) every American is reluctant to be efficientC)every one should have some time to spend as he pleasesD) being punctual is an undesirable habit which should not be formed答案:1.C)deprives us of leisure time 对应原文第一句 but that it is a thief of time when it leaves us no leisure to enjoy ourselves.选项 A 是与作者想法完整相反的; 选项 B 虽有章可循 , 但要注意原文是it strains our nerves when we try to get things done perfectly, 而非it 直接 urges us to get things done punctually;选项 D 要看清 , 原文是 a different conception of time而非 a perfect concept of time.The2.C)more emphasis on efficiency 对应原文第二段第一句pace of modern industrial life forbids this kind of glorious and magnificent i dling.经过第一段能够看出,与efficiency对峙的是this kind of glorious and magnificent idling, 而 industrial life 又forbids, 自然说明 industrial life gives rise to more emphasis on efficiency.3.D)Americans ought not to work so hard for efficiency. 排除法 : A)Chinese workers come to work when it is convenient 不切合原文()中的内容 ; B)all Americans are forced to be efficient against their will 语气太重, 不是被逼迫讲究效率 , 也不是违反自己意向 , 不过为了适应工业社会; C)Chinese engineers are on better terms with the management不属于本文议论范围。

英语四级阅读匹配题模拟练习及答案
20XX年英语四级阅读匹配题模拟练习及答案四级阅读匹配题模拟练习:Definitions of ObesityA) How does one define when a person is considered to be obese and not just somewhat overweight? Height-weight tables give an approximate guideline as to whether one is simply overweight or has passed into the obese stage.B) The World Health Organization recommends using a formula that takes into account a persons height and weight. The "Body Mass Index" (BMI) is calculated by dividing the persons weight in kilograms by the square of their height in meters, and is thus given in units of kg/m2. A BMI of 18.5-24.9 is considered to be the healthiest. A BMI of between 25 and 29.9 is considered to be overweight, while a BMI of over 30 is considered to be obese.C) However, it is recognized that this definition is limited as it does not take into account such variables as age, gender and ethnic origin, the latter being important as different ethnic groups have very different fat distributions. Another shortcoming is that it is not applicable to certain very muscular people such as athletes and bodybuilders, who can also have artificially high BMIs. Agencies such as the National Cholesterol Education Program (NCEP) in the USA and the International Diabetes Foundation (IDF) are starting to define obesity in adults simply in terms of waist circumference.Health Effects of ObesityD) Over 2000 years ago, the Greek physician Hippocrates wrote that "persons who are naturally very fat are apt to die earlier than those who are slender". This observation remains very true today. Obesity has a major impact on a persons physical, social and emotional well-being. It increases the risk of developing diabetes mellitus type 2 ("mature onset diabetes") and also makes Type 2 diabetes more difficult to control. Thus weight loss improves the levels of blood glucose and blood fats, and reduces blood pressure. The association between obesity and coronary heart disease is also well-known.CancerE) Furthermore, in 2001 medical researchers established a link between being overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer as a result of being overweight. This figure was made up of 5,893 women and 3,220 men, with the strongest associations being with breast and colon cancers. However, it is thought that being overweight may also increase the risk of cancer in the reproductive organs for women and in the prostate gland for men.F) The link between breast cancer and nutritional status is thought to be due to thesteroid hormones oestrogen and progesterone, which are produced by the ovaries, and govern a womans menstrual cycle. Researchers have found that the more a woman eats, or the more sedentary her lifestyle, the higher are the concentrations of progesterone. This link could explain why women from less affluent countries have lower rates of breast cancer. Women from less affluent nations tend to eat less food and to leadlifestyles which involve more daily movement. This lowers their progesterone level, resulting in lower predisposition to breast cancer.G) The Times newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world!AgingH) Research published by St Thomas Hospital, London, UK in 2005 showed a correlation between body fat and aging, to the extent that being obese added 8.8 years to a womans biological age. The effect was exacerbated by smoking, and a non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The combination of being obese and a smoker added at least ten years to a womans biological age, and although the study only involved women, the lead researcher Professor Tim Spector believes the finding would also apply to men.I) The aging effect was determined by measuring the length of telomeres, tiny "caps" on the ends of chromosomes, which help protect the DNA from the ageing process. Indeed, telomeres have been dubbed the "chromosomal clock" because, as an organism ages, they become progressively shorter, and can be used to determine the age of the organism. Beyond a certain point, the telomere becomes so short that it is no longer able to prevent the DNA of the chromosome from falling apart. It is believed that excess body fat, and the chemicals present in tobacco smoke release free radicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres.DementiaJ) Recent research (2005) conducted in the USA shows that obesity in middle age is linked to an increased risk of dementia, with obese people in their 40s being 74% more likely to develop dementia compared to those of normal weight. For those who are merely overweight, the lifetime risk of dementia risk was 35% higher.K) Scientists from the Aging Research Centre at the Karolinska Institute in Sweden have been able to take information such as age, number of years in education, gender, body mass index, blood pressure level, physical activity and genetic factors, assigning each a risk score. They then used this information to devise a predictive test for dementia. This test will enable people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk of contracting dementia.Other ProblemsL) The world-wide upsurge in obesity, particularly in children, is of major economic concern, liable to drain economies. Of further concern is that research conducted in Australia and published in 2006, shows that up to one third of breech pregnancies were undetected by the traditional "palpation" examination, the danger being greatest for those women who are overweight or obese—a growing proportion of mothers. This means that such women are not getting the treatment required to turn the baby around in time for the birth, and in many cases require an emergency Caesarean section.M) This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome (SARS) and ultimately, even bigger than AIDS.对应题目:1. You can judge whether one is simply overweight or has passed into the obese stage according to the height-weight table.2. Using the "Body Mass Index"to define a persons weight ideal is limited, because it does not takes into account many variables such as age, gender and ethnic origin.3. A persons emotional well-being would be affected by obesity.4. Obesity has something to do with cancer in the prostate gland for man.5. Women from less affluent nations tend to have much less breast cancer.6. A non-overweight woman who smokes 20 cigarettes a day for 20 years added7.4 years to her biological age.7. The excess body fat, like the chemicals present in tobacco smoke, can lead to inflammation.8. Obese people in middle age run an increased risk of dementia .9. The predictive test for dementia will help people to affect lifestyle changes that will reduce their risk of contracting dementia.10. The world-wide upsurge in obesity, particularly in children, will possibly drain economies.参考答案:1. A2. C3. D4. E5. F6. H7. I8. J9. K10. L。

Early in the 1900s most American towns and cities had a Main Street. Main Street was always in the 1 of a town. This street was lined on the both sides with 2 businesses. Here, shoppers walked into stores to look at all sorts of merchandise: clothing, furniture, hardware, groceries. In addition, some shops offered 3 . These shops included drugstores, restaurants, shoe repair stores, and barber or hairdressing shops. But in the 1950s, a change began to 4 place. Too many automobiles had crowded into Main Street while too few parking places were 5 to shoppers. Because the streets were crowded, merchants began to look with interest at the open spaces outside the city limits. Open space is what their car driving customers 6 . And open space is what they got when the first shopping center was built. Shopping centers, or rather malls, 7 as a collection of small new stores away from crowded city centers. Attracted by hundreds of free parking space, customers were drawn away from 8 areas to outlying malls. And the growing 9 of shopping centers led in turn to the building of bigger and better stocked stores, By the late 1970s, many shopping malls had almost developed into small cities themselves. In addition to providing the 10 of one-stop shopping, malls were transformed into landscaped parks, with benches, fountains, and outdoor entertainment.A.designed B.take C.heart D.ne ededE.though F.convenience G.services H.fame I.various J.popularity K.cosmetics L.started M.downtown N.available O.cheapnessIn science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists envision the way an observed event could be 11 . A good example of this is found in the kinetic molecular theory (分子运动论), in which gases are pictured as being made up of many small 12 that are in constant motion. A 13 theory, in addition to explaining past observations, helps to predict events that have not as yet been observed. After a theory has been 14 , scientists design experiments to test the theory. If observations do not 15 the predictions, the scientists must search 16 . There may be a fault in the experiment, or the theory may have to be revised or rejected. Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves are notscience. As the mathematician Jules Henry Poincare said: "Science is 17 with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house." Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been 18 , the scientist comes to the part of the investigation that requires 19 imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses.In a way, any hypothesis is a leap into the unknown. It extends the scientist's thinking beyond the 20 facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When confirmed, they are incorporated into theories.A.nearly B.useful C.considerable D .considerateE.published F.publicized G.gathered H .producedI.built J.made K.known L.confirmM.particles N.parts O.furtherSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter.Preparing For Computer DisastersA.Fires, power surges, and floods, they're all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate (怜悯,同情) over their bad luck. We also shake our heads at the digital consequences—melted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra (祷文) of denial: "It won't happen to me." Well, the truth is, at some point you'll probably have to deal with at least one disaster. That's just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason, computer disaster recovery is a blind spot for many of us. It shouldn't be.B.Home computers contain some of our most important information, both business and personal, and making certain our data survives a disaster should be a priority. Moreover, even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and they're even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a good offsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a majorcalamity strike, you can rest assured your data is safe.Offsite Storage: Major DisastersC.House fires and floods are among the most devastating causes of personal computer destruction. That's why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their house flood or burn. That's because they keep their backups relatively close to their computers. Their backup disks might not be in the same room as their computers—tucked away in a closet or even the garage—but they're not nearly far enough away should a serious disaster strike. So, it's important to back up your system to a removable medium and to store it elsewhere.D.There are many ways to approach offsite storage. It starts with a choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldn't add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in a pinch. They must also be compatible with your choice of backup medium. Depending on your tools, you can back up to a variety of durable disk types—from CDs to Jazz drives to remote network servers. Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.E.Once you select your tools and a suitable medium, you need to find a remote place to store your backups. The options are endless. However, no matter where you choose, be sure the site is secure, easily accessible, and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractive alternative to conventional offsite storage. Of course, before using one of these services, make certain you completely trust the service provider and its security methods. Whatever you do, schedule backups regularly and store them far away from your home.Come What May: Handling the Garden Variety Computer CrisisF.Not all home computer damage results from physical disaster. Many less menacing problems can also hobble your PC or destroy your information. Systems crash, kids "rearrange" data, adults inadvertently delete files. Although these events might not seem calamitous, they can have serious implications. So, once again, it's important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a response that's more nuanced (有细微差别的) than wholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and agile (敏捷的). For example, when a small number of files are compromised, you may want to retrieve those files alone. Meanwhile, if just your settings are affected, you'll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, you'll need a way to boot your computer and perform large-scale recovery. Computer crises come in all shapes and sizes, and your backup and recovery tools must be flexible enough to meet each challenge.The Right Tools for the Right Job: Gearing up for DisasterG.When disaster strikes, the quality of your backup tools can make the difference between utter frustration and peace of mind. Symantec understands this and offers a range of top quality backup and recovery solutions. Norton GoBack is the perfect tool for random system crashes, failed installations, and inadvertent deletions. With this powerful and convenient solution, it's simple to retrieve overwritten files or to bring your system back to its pre-crash state. Norton Ghost is a time-tested home office solution. Equipped to handle full-scale backups, it's also handy for cloning hard drives and facilitating system upgrades. A favorite choice for IT professionals, it's the ideal tool for the burgeoning home office. You can buy Norton Ghost and Norton GoBack separately, or get them both when you purchase Norton System Works.H.Life's disasters, large and small, often catch us by surprise. However, with a little planning and the right tools, you can reduce those disasters to bumps in the road. So, don't wait another day. Buy a good set of disaster recovery tools, set up an automatic backup schedule, and perform a dry run every now and again. Then, rest easy.21、You should prepare for your computer disasters now and again.22、The backup and recovery tools must be flexible enough to deal with various computer crises.23、For some reason, computer disaster recovery is always ignored by many of us.24、The most devastating causes of personal computer destruction includes house fires and floods.25、You should find a distant place to store your backups after selecting your tools and a suitable medium.26、You can bounce back quickly and easily minor computer disasters with the help of a good offsite storage plan and the right tools.27、Not only physical disaster can damage your computer.28、It's necessary for us to back up our systems to some transferable medium and to put it somewhere else.29、The quality of your backup tools determines whether you are frustrated or have a peaceful mind when disaster strikes.30、You should take steps to recover from computer disasters so as to minimize their effects.Paper—More Than Meets The EyeA.We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far more difficult to spot the grades. It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst the corn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It is also much cheaper to manufacture than high grade card.B.Paper can be made from an almost endless variety of cellulose (纤维)-based material which will include many woods, cottons and grasses, of whichpapyrus is an example and from where we get the word "paper". Many of these are very specialized, but the preponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based.Paper from WoodC.In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalies (碱) such as caustic soda, until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell is the essence of paper making from wood. However, the reality is rather more complicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals.D.A further problem with wood is that it contains a material that is not cellulose, something called lignin (木质素). This is essential for the tree since it holds the cellulose fibers together, but if it is incorporated into the manufactured paper it presents archivists (档案员) with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. We have all seen this in old newspapers and cheap paperback books. It has been estimated that most paper back books will have a life of not greater than fifty years. Not what we need for our archives.E.Since the lignin can be removed from the paper pulp during manufacture, the obvious question is "why is it left in the paper?" The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly uneconomic to remove the lignin for many paper and card applications.F.It also means, of course, that lignin-free paper is going to be more expensive, but that is nevertheless what the archivist must look for in his supplies. There is no point whatsoever in carefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid (酸) is particularly harmful to photographic materials, causing them to fade and in some cases simply vanish!G.So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the right conditions it will speed up enormously.H.Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on, the correct material then this is probably the only way. Incidentally, acids can migrate from material to material. Lining oldshoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end.Paper from RagI.Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to purchase from a reliable source though, since even rag paper and card can contain undesirable additives. A reliable source for quality rag papers is a recognized art stockist. Many water color artists insist on using only fine quality rag paper and board.J.The main lesson to learn from this information is that you cannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.31、During the whole manufacturing process, the final product is made from a pulp of cellulose fibers.32、The corn-flake packet is cheaper than high grade card.33、There are a lot of materials which can be used for making paper, but the superiority ones are soft wood, cotton and rags.34、Although free of lignin, paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less cotton and rag than trees.35、Lignin is essential for the tree but it will make paper easy to break.36、Many paper producers will preserve lignin during manufacture, because leaving the lignin will make more paper from a tree.37、In order to make white paper and card, the makers will add bleach.38、Acid is particularly harmful to photographic materials.39、What we can learn from "Paper from Rag" is that you had better buy archival materials from specialist suppliers.40、The lignin is commonly not removed from the paper, as the ligin-free paper will be more expensive.Section CDirections: There are 2 passages in this section. 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 Answer Sheet 2 with a single line through the centre.Passage OneThe fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label: "store in the refrigerator."In my fridgeless fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes. Nothing was wasted, and we were nevertroubled by rotten food. Thirty years on, food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well-tried techniques already existed—natural cooling, drying, smoking, salting, sugaring, bottling. What refrigeration did promote was marketing—marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the globe in search of a good price.Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house—while outside, nature provides the desired temperature free of charge.The fridge's effect upon the environment has been evident, while its contribution to human happiness has been insignificant. If you don't believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburger, but at least you'll get rid of that terrible hum.41、The statement "In my fridgeless fifties childhood, I was fed well and healthily." (Para. 2) suggests that ______.A.the author was well-fed and healthy even without a fridge in his fiftiesB.the author was not accustomed to using fridges even in his fiftiesC.the fridge was in its early stage of development in the 1950sD.there was no fridge in the author's home in the 1950s42、Why does the author say that nothing was wasted before the invention of fridges?A.People would not buy more food than was necessary.B.Food was delivered to people two or three times a week.C.People had effective ways to preserve their food.D.Food was sold fresh and did not get rotten easily.43、Who benefited the least from fridges according to the author?A.Inventors. B.Manufacturers.C.Consumers. D.Traveling salesmen.44、Which of the following phrases in the fourth paragraph indicates the fridge's negative effect on the environment?A.With mild temperatures. B.Climatically almost unnecessary.C.Artificially-cooled space. D.Hum away continuously.45、What is the author's overall attitude toward fridges?A.Critical. B.Objective.C.Neutral. D.Compromising.I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded thattoday's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.Why are America's kids so stressed? The report cites two main causes: increasing physical isolation—brought on by high divorce rates and less involvement in community, among other things—and a growing perception that the world is a more dangerous place.Given that we can't turn the clock back, adults can still do plenty to help the next generation cope.At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.Limit the amount of virtual (虚拟的) violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news.Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have to ruin your life.46、The author thinks that the conclusions of any research about people's state of mind are ______.A.surprising B.confusingC.illogical D.questionable47、What does the author mean when he says, "we can't turn the clock back" (Para. 3)?A.It's impossible to slow down the pace of change.B.The social reality children are facing cannot be changed.C.Lessons learned from the past should not be forgotten.D.It's impossible to forget the past.48、According to an analysis, compared with normal children today, children treated as mentally ill 50 years ago ______.A.were less isolated physically B.were probably less serf-centeredC.probably suffered less from anxiety D.were considered less individualistic49、The first and most important thing parents should do to help their children is ______.A.to provide them with a safer environmentB.to lower their expectations for themC.to get them more involved sociallyD.to set a good model for them to follow50、What conclusion can be drawn from the passage?A.Anxiety, though unavoidable, can be coped with.B.Children's anxiety has been enormously exaggerated.C.Children's anxiety can be eliminated with more parental care.D.Anxiety, if properly controlled, may help children become mature.Passage TwoFood can be divided into two basic categories: real food and pleasure food. Real food is fuel for the body's needs, while pleasure food, which is high in fat and sugar, is primarily for taste satisfaction. The categories are pretty obvious. Broccoli (西兰花) is real food. Cookies are in the pleasure group.When you are hungry, you are faced with choices. If you aren't suffering from excessive hunger, you can be rational about them. Go to the refrigerator. What looks good? If you have chosen a real food, say, a turkey sandwich, you can be certain your body can use it for fuel. Eat it and enjoy.Two hours later you are hungry again. Back to the refrigerator. What looks good? Ice cream. Stop! Employ your will power just a little. Ice cream is not what your body needs. Does something else look good? Yes, a piece of toast with peanut butter and a glass of milk sound good too. Okay, go ahead, remembering that high-fat real foods should be eaten in moderation.One trick is to eliminate pleasure foods from your kitchen. Instead, keep a variety of high-quality foods available at all times. In short, buy lots of delicious real food, food you really like, and get rid of the junk.But what if you have ice cream on hand and nothing sounds good? Although you don't want to eat pleasure food whenever the urge strikes, there is a legitimate place for them in your diet. If you have analyzed your feelings and there are no other needs imitating hunger, eat the ice cream. You have not failed. On the contrary, you have accepted your natural appetite, but not blindly.Surprisingly, when you know you can eat anything you want, and that you never have to put up with unsatisfied hunger again, it takes a lot of pressure off. You will begin to want to eat what your body needs, and your body will begin to need foods that will lead to slimness.51、Which of the following statements is NOT true?A.The author is against getting rid of pleasure food altogether.B.One can eat the high-fat real foods heartily since it is fuel for the body.C.Make sure to keep pleasure food such as ice cream in your diet.D.Of course you can sometimes have ice cream if you really want to.52、What would be the best title for this passage?A.Real Food And Pleasure Food.B.Reducing Weight.C.Limit Your Consumption Of Pleasure Food.D.How To Choose Food When You Are Hungry.53、What can you assume from the last paragraph?A.Being able to eat anything doesn't necessarily imply pleasure.B.Real foods may lead to slimness.C.Eat only what your body needs.D.Be sure to satisfy your hunger whenever it strikes you.54、What can real food be except ______.A.ice cream B.cauliflowerC.a turkey sandwich D.a piece of toast55、Judging from the fourth paragraph, what does "junk" mean?A.Food like ice cream. B.Food you do not like.C.Pleasure foods. D.Low-quality foods.Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age.People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. "The idea is not necessarily to learn to memorize enormous amounts of information," says James Fozard, associate director of the National Institute on Aging. "Most of us don't need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness." Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. "The point is, you need to do both," Cohen says. "Intellectual activity actually influences brain-cell health and size."56、People who are cognitively healthy are those ______.A.whose minds are alert and receptiveB.who are highly intelligentC.who can remember large amounts of informationD.who are good at recognizing different sounds57、According to Fozard's argument, people can make their brains work more efficiently by ______.A.constantly doing memory workB.making frequent adjustmentsC.going through specific trainingD.taking part in various mental activities58、The findings of James Fozard and other scientists in their work ______.A.remain a theory to be further proved。
大学英语四级阅读模拟题及答案(3篇)
大学英语四级阅读模拟题及答案阅读1空调的危害Although many of us may feel air-conditioners bring relief from hot,humid or polluted outside air,they pose many potential health hazards.Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.One of the more widely publicized dangers is that of Legionnaire’s disease,which was first recognized inthe1970s.This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’cooling towers was somehow sucked back into the air intake(通风口),in mostcases due to poor design.The warm air,filled with bacteria,was combined with cooled,conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.Large air-conditioning systems add water to the air they circulate by means of humidifiers(湿度调节器).Inolder systems,the water used for this process is kept in special reservoirs,the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通风)system.The risk to human health from this situation has been highlighted by the fact that the immune systems(免疫系统)of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called“biocides”are added to reservoirs to make them germ-free,and they are dangerous in their own right in sufficient quantities,as they often contain compounds strongly linked to cancers.Finally,it should be pointed out that the artificial climatic environment created byair-conditioners canalso affect us.In a natural environment,whether indoor or outdoor,there are small variations in temperature and humidity.Indeed,the human body has long been accustomed to these normal changes.In an air-conditioned living or working environment,however,body temperatures remain well under37℃,our normal temperature.This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.练习题:Choose correct answers to the question:1.What do we know about Legionnaire's disease from the passage?A.It was the most widely concerned office hazard.B.It can affect people both inside and outside the building.C.It happens only in air-conditioned office buildings.D.It does not develop in well-designed buildings.2.In the old air-conditioned systems,bacteria first develop______.A.in the reservoirsB.in the ventilation systemc.in the humidifiersD.in the air intake3.The fact that about half of workers developed the ability to fight off the bacteria may__.A.relieve people’s worry about the danger caused by the bacteriaB.help people find an effective way to get rid of the bacteriaC.reflect the serious danger brought by the bacteriaD.cause serious disease such as cancers to people4.The author most probably wants the readers to treat biocides with an attitude of_.A.cautionB.trustC.enthusiasmD.criticism5.The last paragraph implies that our immune system can be weakened when_•A.we live in an artificial climatic environmentB.there are variations in temperature and humidityC.our body temperatures often remain not high enoughD.we are often exposed to diseases such as colds and flu答案解析:1.[B]事实细节题。

英语四级考试阅读模拟题(一)Where do pesticides fit into the picture of environmental disease? We have seen that they now pollute soil,water and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world: We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farmworkers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time, and that the danger to individual may depend on the sum of the exposures received throughout his lifetime. For these veryreasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. Men are naturally most impressed by diseases which have obvious signs, says a wise physician, Dr Rene Dubos, yet some of their worst enemies slowly approach them unnoticed.练习题:Choose correct answers to the question:1.Which of the following is closest in meaning to the sentence Manis part of nature (Para. 1, Lines 3-4)?A. Man appears indifferent to what happens in nature.B. Man acts as if he does not belong to nature.C. Man can avoid the effects of environmental pollution.D. Man can escape his responsibilities for environmental effects of pesticides?2. What is the authors attitude toward the environmental effects of pesticides?A. PessimisticB. IndifferentC. DefensiveD. Concerned3. In the authors view, the sudden death caused by exposure to large amounts of pesticides _____.A. is not the worst of the negative consequences resulting from the use of pesticidesB. now occurs most frequently among all accidental deathsC. has sharply increased so as to become the center of public attentionD. is unavoidable because people cant do without pesticides in farming4. People tend to ignore the delayed effects of exposure to chemical because _____.A. limited exposure to them does little harm to peoples healthB. the present is more important for them than the futureC. the danger does not become apparent immediatelyD. humans are capable of withstanding small amounts of poisoning5. It can be concluded from Dr. Dubos remarks that _____.A. people find invisible diseases difficult to deal withB. attacks by hidden enemies tend to be fatalC. diseases with obvious signs are easy to cureD. people tend to overlook hidden dangers caused by pesticides英语四级考试阅读模拟题答案1.[B] 题干的句子是文章第1段第3句,这是一个带有插入语的简洁句,contrary在此表示跟part of nature相反,因此答案为B。
英语四级阅读理解模拟试题附答案
英语四级阅读理解模拟试题附答案英语四级阅读理解模拟试题:【原文】There are two factors which determine an individuals intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individuals intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(抚养) homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Marks I. Q. was 125, twenty-five points higherthan the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.英语四级阅读理解模拟试题:【题目】21. This selection can best be titled____________.A.

PART V READING COMPREHENSION [25 MIN]In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.TEXT AWe can begin our discussion of "population as global issue" with what most persons mean when they discuss "the population problem": too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to "a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes."To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world's population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.1.Which of the following demographic growth pattern is most suitable for the long thin powder fuse analogy?A.A virtually stable or slightly decreasing period and then a sudden explosion of population.B.A slow growth for a long time and then a period of rapid, dramatic increase.C.Too many people on earth and a few rapid increase in the number added each year.D.A long period when death rates exceeds birthrates and then a short period with higher fertility and lowermortality.2.During the first period of demographic history, societies were often in danger of extinction because___.A.only one in ten persons could live past 40.B.there was higher mortality than fertility in most places.C.it was too dangerous to have babies due to the poor conditions.D.our ancestors had little enthusiasm for more children.3.Which statement is true about population increase?A.There might be an increase of 2.2 billion persons from now to the year 2000.B.About 50,000 babies are born every six hours at present.C.Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.D.The population increased faster between 8000BC and 1650 than between 1650 and the present.4.The author of the passage intends to___.A.warn people against the population explosion in the near future.pare the demographic growth pattern in the past with that after 1650.C.find out the cause for rapid increase in population in recent years.D.present us a clear and complete picture of the demographic growth.5.The word "demographic" in the first paragraph means___.A.statistics of human.B.surroundings study.C.accumulation of human.D.development of human.TEXT BChinese Americans today have higher incomes than Americans in general and higher occupational status. The Chinese have risen to this position despite some of the harshest discrimination and violence faced by any immigrants to the United States in the history of this country. Long confined to a narrow range of occupations they succeeded in those occupations and then spread out into other areas in later years, when opportunities finally opened up for them. Today much of the Chinese prosperity is due to the simple fact that they work more and have more (usually better) education than others. Almost one out of five Chinese families has three or more income earners compared to one out of thirteen for Puerto Ricans, one out of ten among American Indians, and one out of eight among Whites. When the Chinese advantages in working and educational are held constant, they have no advantage over other Americans. That is in a Chinese Family with a given number of people working and with a given amount of education by the head of the family, the income is not only about average for such families, and offer a little less than average.While Chinese Americans as a group are prosperous and well-educated Chinatowns are pockets of poverty, and illiteracy is much higher among the Chinese than among Americans in general. Those paradoxes are due to sharp internal differences. Descendants of the Chinese Americans who emigrated long ago from Toishan Province have maintained Chinese values and have added acculturation to American society with remarkable success. More recent Hong Kong Chinese are from more diverse cultural origins, and acquired western values and styles in Hong Kong, without having acquired the skills to proper and support those aspirations in the American economy. Foreign-born Chinese men in the United States are one-fourth lower incomes than native-born Chinese even though the foreign-born have been in the United States an average of seventeen years. While the older Hong Kong Chinese work tenaciously to sustain and advance themselves, the Hong Kong Chinese youths often react with resentment and antisocial behavior, including terrorism and murder. The need to maintain tourism in Chinatown causes the Chinese leaders to mute or downplay these problems as much as possible.6.According to the passage, today, Chinese Americans owe their prosperity to___.A.their diligence and better education than others.B.their support of American government.C.their fight against discriminations.D.advantages in working only.7.The passage is mainly concerned with___.A.chinese Americans today.B.social status of Chinese Americans today.C.incomes and occupational status of Chinese Americans today.D.problems of Chinese Americans today.8.Chinatowns are pockets of poverty, as is probably associated with___.A.most descendants of Chinese Americans are rebelling.B.most descendants of Chinese Americans are illiterate.C.sharp internal difference between Chinese coming from different cultural backgrounds.D.only a few Chinese Americans are rich.9.Which of the following statements is not true according to this articleA.As part of the minority, Chinese Americans are still experiencing discrimination in American today.B.Nowadays, Chinese Americans are working in wider fields.C.Foreign-born Chinese earn lower income than native-born Chinese Americans with the similar advantagesin the U.S.D.None of the above.10.According to the author, which of the following can best describe the older Hong Kong Chinese and theyoungerA.Tenacious; rebellion.B.Conservative; open-minded.C.Out-of-date; fashionable.D.Obedient; disobedient.TEXT CA controversy erupted in the scientific community in early 1998 over the use of DNA (deoxyribonucleic acid ) fingerprinting in criminal investigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA, the molecule of which genes are made. DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. However, it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to trove guilt, not just establish innocence. When used in criminal investigations, a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime. A match between the two DNA samples can be used as evidence to convict a suspect.The controversy in 1998 stemmed form a report published in December 1991 by population geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass., and Daniel L. Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone. In particular, they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNA patterns methods are adequate.In response to their criticisms, population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven, Conn., argued that enough data are already available to show that the methods currently being used are adequate. In January 1998, however, the federal Bureau of Investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples form various ethnic groups in an attempt to resolve some of these questions. And, in April, a National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.11.efore DNA fingerprinting is used, suspects____.A.would have to leave their fingerprints for further investigationsB.would have to submit evidence for their innocenceC.could easily escape conviction of guiltD.cold be convicted of guilt as well12.DNA fingerprinting can be unreliable when ____.A.the methods used for blood- cell calculation are not accurateB.two different individuals of the same ethnic group may have the same DNA fingerprinting patternC.a match is by chance left with fingerprints that happen to belong to two different individualsD.two different individuals leave two DNA samples.13.To geneticists like Lewontin and Hartl, the current method ____.A.is not so convincing as to exclude the likelihood that two DNA samples can never come from twoindividualsB.is arguable because two individuals of the same ethnic group are likely to have the same DNA pattern.C.Is not based on adequate scientific theory of geneticsD.Is theoretically contradictory to what they have been studying14.The attitude of the Federal Bereau of Investigation shows that ____.A.enough data are yet to be collected form various ethnic groups to confirm the unlikelihood of two DNAsamples coming from two individual membersB.enough data of DNA samples should be collected to confirm that only DNA samples form the same personcan matchC.enough data are yet to be collected from various ethnic groups to determine the likelihood of two differentDNA samples coming form the same personD.additional samples from various ethnic groups should be collected to determine that two DNA samples areunlikely to come from the same person15.National Academy of Sciences holds the stance that ____.A.DNA testing should be systematizedB.Only authorized laboratories can conduct DNA testingC.The academy only is authorized to work out standards for testingD.The academy has the right to accredit laboratories for DNA testingTEXT DMost of us are taught to pay attention to what is said—the words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiveness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We don't always say what we mean or mean what we say. Sometimes our words don't mean anything except " I'm letting off some steam. I don't really want you to pay close attention to what I'm saying. Just pay attention to what I'm feeling." Mostly we mean several things at once. A person wanting to purchase a house says to the current owner, "This step has to be fixed before I'll buy." The owner says, " It's been like that for years." Actually, the step hasn't been like that for years, but the unspoken message is: " I don't want to fix it. We put up with it. Why can't you?" The search for a more expansive view of meaning can be developed of examining a message 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 deal more than the frequency of the behavior.A friend's unusually docile behavior may only be understood by noting that it was preceded by situations that required an abnormal amount of assertiveness. Some responses may be directly linked to a developing pattern of responses and defy logic. For example, a person who says "No!" to a serials of charges like "You're dumb," "You're lazy," and "You're dishonest," may also say "No!" and try to justify his or her response if the next statement is "And you're good looking."We would do well to listen for how messages are presented. The words, "If sure has been nice to have you over," can be said with emphasis and excitement or ritualistically. The phrase can be said once or repeated several times. And the meanings we associate with the phrase will change accordingly. Sometimes if we say something infrequently it assumes more importance; sometimes the more we say something the less importance it assumes.16.Effective communication is rendered possible between two conversing partners, if ___.A.they use proper words to carry their ideas.B.they both speak truly of their own feelings.C.they try to understand each other's ideas beyond words.D.they are capable of associating meaning with their words.17."I'm letting off some steam" in paragraph 1 means___.A.I'm just calling your attention.B.I'm just kidding.C.I'm just saying the opposite.D.I'm just giving off some sound.18.The house-owner's example shows that he actually means___.A.the step has been like that for years.B.he doesn't think it necessary to fix the step.C.the condition of the step is only a minor fault.D.the cost involved in the fixing should be shared.19.Some responses and behaviors may appear very illogical, but are justifiable if___.A.linked to an abnormal amount of assertiveness.B.seen as one's habitual pattern of behavior.C.taken as part of an ordering sequence.D.expressed to a series of charges.20.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: 1-5 ABADA 6-10 ACCCA 11-15 CBABB 16-20 DBABC。

For each question, there are four suggested answers marked [A], [B], [C] and [D]. Choose the one that you think is the best answer.(1) The schoolmaster was leaving the village, and everybody seemed sorry. The miller at Cresscombe lent him the small white tilted cart and horse to carry his goods to the city of his destination, about twenty miles off, such a vehicle proving of quite sufficient size for the departing teacher’s effects. For the schoolhouse had been partly furnished by the managers, and the only cumbersome article possessed by the master, in addition to the packing-case of books, was a cottage piano. (2)The blacksmith, the farm bailiff, and the schoolmaster himself were standing in perplexed attitudes in the parlour before the instrument. The master had remarked that even if he got it into the cart he should not know what to do with it on his arrival at Christminster, the city he was bound for, since he was only going into temporary lodgings just at first. (3) A little boy of eleven, who had been thoughtfully assisting in the packing, joined the group of men, and as they rubbed their chins he spoke up, blushing at the sound of his own voice: “Aunt have got a great fuel-house, and it could be put there, perhaps, till you’ve found a place to settle in, sir.”(4) “A proper good notion,” said the blacksmith. (5) “Sorry I am going, Jude?” asked the master kindly. (6) Tears rose into the boy’s eyes, for he was not among the regular day scholars, who came unromantically close to the schoolmaster’s life, but one who had attended the night school only during the present teacher’s term of office. The regular scholars, if the truth must be told, stood at the present moment afar off, like certain historic disciples, indisposed to any enthusiastic volunteering of aid.(7) The boy awkwardly opened the book he held in his hand, which Mr. Phillotson had bestowed on him as a parting gift, and admitted that he was sorry. (8) “So am I,” said Mr. Phillotson. (9) “Why do you go, sir?” asked the boy. (10) “Ah—that would be a long story. You wouldn’t understand my reasons, Jude. You will, perhaps, when you are older.”(11) “I think I should now, sir.”(12) “Well—don’t speak of this everywhere. YoUKnow what a university is, and a university degree? It is the necessary hallmark of a man who wants to do anything in teaching. My scheme, or dream, is to be a university graduate, and then to be ordained. By going to live at Christminster, or near it, I shall be at headquarters, so to speak, and if my scheme is practicable at all, I consider that being on the spot will afford me a better chance of carrying it out than I should have elsewhere.”(13) The boy Jude assisted in loading some small articles, and at nine o’clock Mr. Phillotson mounted beside his box of books and other IMPEDIMENTA, and bade his friends good-bye.(14) “I shan’t forget you, Jude,” he said, smiling, as the cart moved off. “Be a good boy, remember; and be kind to animals and birds, and read all you can. And if ever you come to Christminster remember you hunt me out for old acquaintance’ sake.”(15) The cart creaked across the green, and disappeared round the corner by the rectory-house. The boy returned to the draw-well at the edge of the greensward, where he had left his buckets when he went to help his patron and teacher in the loading. There was a quiver in his lip now and after opening the well-cover to begin lowering the bucket he paused and leant with his forehead and arms against the framework, his face wearing the fixity of a thoughtful child’s who has felt the pricks of life somewhat before his time. The well into which he was looking was as ancient as the village itself, and from his present position appeared as a long circular perspective ending in a shining disk of quivering water at a distance of a hundred feet down. There was a lining of green moss near the top, and nearer still the hart’s-tongue fern. (16) He said to himself, in the melodramatic tones of a whimsical boy, that the schoolmaster had drawn at that well scores of times on a morning like this, and would never draw there any more. “I’ve seen him look down into it, when he was tired with his drawing, just as I do now, and when he rested a bit before carrying the buckets home! But he was too clever to bide here any longer—a small sleepy place like this!”1.The schoolmaster held a perplexed attitude towards his piano, because it became a ______ under his current condition.A.white elephantB.black sheepC.dark horseD.busy bee正确答案:A解析:原文第一段和第二段提到小学老师要离开的时候,最为笨重的物件就是一架竖式钢琴,而老师表示这件东西即使弄上车,他刚到目的地的时候也没有地方安顿它,所以大家都感到有些一筹莫展。

高校英语四级阅读理解试题是试卷中分值最重的题型,为了提高大家的阅读水平,下面是我为大家带来英语四级阅读理解模拟练习及答案详解,盼望对大家的学习有所关心!Directions:There are 2 passages in this section.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 Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among "situations vacant', although it does not offer anyone a job, and sometimes it appears among "situations wanted', although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job."Contact us before writing your application', or "Make use of our long experience in preparing your curriculum vitae or job history', is how it is usually expressed. The growth and apparentsuccess of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right.There was a time when job seekers simply wrote letters of application. "Just put down your name, address, age and whether you have passed any exams', was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. "Your search is over. I am the person you are looking for', was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job interview.There is no doubt, however, that it is increasing number ofapplicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.57. The new type of advertisement which is appearing in newspaper columns .A) informs job hunters of the opportunities availableB) promises to offer useful advice to those looking for employmentC) divides available jobs into various typesD) informs employers of the people available for work58. Nowadays a demand for this specialized type of service has been created because .A) there is a lack of jobs available for artistic peopleB) there are so many top?level jobs availableC) there are so many people out of workD) the job history is considered to be a work of art59. In the past it was expected that first job hunters would .A) write an initial letter giving their life historyB) pass some exams before applying for a jobC) have no qualifications other than being able to read and writeD) keep any detailed information until they obtained aninterview60. Later, as one went on to apply for more important jobs, one was advised to include in the letter .A) something that would distinguish one from other applicantsB) hinted information about the personality of the applicantC) ones advantages over others in applying for the jobD) an occasional trick with the aggressive approach61. The curriculum vitae has become such an important document because .A) there has been an increase in the number of jobs advertisedB) there has been an increase in the number of applicants with degreesC) jobs are becoming much more complicated nowadaysD) the other processes of applying for jobs are more complicatedPassage TwoQuestions 62 to 66 are based on the following passage.In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that aftera long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rentcontrolled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, lowpaying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if "other things are equal'. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.62. There is the possibility that setting maximum rent may .A) cause a shortage of apartmentsB) worry those who rent apartments as homesC) increase the profits of landlordsD) encourage landlords to invest in building apartment63. According to the critics, rent control .A) will always benefit those who rent apartmentsB) is unnecessaryC) will bring negative effects in the long runD) is necessary under all circumstances64. The problem of unemployment will arise .A) if the minimum wage is set too highB) if the minimum wage is set too lowC) if the workers are unskilledD) if the maximum wage is set65. The passage tells us .A) the relationship between supply and demandB) the possible results of government controlsC) the necessity of government controlD) the urgency of getting rid of government controls66. Which of the following statements is NOT true?A) The results of economic decisions can not always be predicted.B) Minimum wage can not always protect employees.C) Economic theory can predict the results of economic decisions if other factors are not changing.D) Economic decisions should not be based on economic theory.答案详解:57.

At 12.6 percent, it is now higher than at any point since the mid1920s.We are not about to go back to the days when Congress openly worried about inferior races polluting America’s bloodstream. But once again we are wondering whether we have too many of the wrong sort newcomers. Their loudest critics argue that the new wave of immigrants cannot, and indeed do not want to, fit in as previous generations did.We now know that these racist views were wrong. In time, Italians, Romanians and members of other so-called inferior races became exemplary Americans and contributed greatly, in ways too numerous to detail, to the building of this magnificent nation. There is no reason why these new immigrants should not have the same success.Although children of Mexican immigrants do better, in terms of educational and professional attainment, than their parents U CLA sociologist Edward Telles has found that the gains don’t continue. Indeed, the fouth generation is marginally worse off than the third James Jackson, of the University of Michigan, has found a similar trend among black Caribbean immigrants, Tells fears that Mexican-Americans may be fated to follow in the footsteps of American blacks-that large parts of the community may become mired(陷入)in a seemingly permanent state of poverty and Underachievement. Like African-Americans, Mexican-Americans are increasingly relegated to (降入)segregated, substandard schools, and their dropout rate is the highest for any ethnic group in the country.We have learned much about the foolish idea of excluding people on the presumption of the ethnic/racial inferiority. But what we have not yet learned is how to make the process of Americanization work for all. I am not talking about requiring people to learn English or to adopt American ways; those things happen pretty much on their own, but as arguments about immigration hear up the campaign trail, we also ought to ask some broader question about assimilation, about how to ensure that people , once outsiders , don’t forever remain marginalized within these shores.That is a much larger question than what should happen with undocumented workers, or how best to secure the border, and it is one that affects not only newcomers but groups that have been here for generations. It will have more impact on our future than where we decide to set the admissions bar for the latest ware of would-be Americans. And it would be nice if we finallygot the answer right.1. How were immigrants viewed by U.S. Congress in early days?A) They were of inferior races.B) They were a Source of political corruption.C) The y were a threat to the nation’s security.D) They were part of the nation’s bloodstream.2. What does the author think of the new immigrants?A) They will be a dynamic work force in the U.S.B) They can do just as well as their predecessors.C) They will be very disappointed on the new land.D) They may find it hard to fit into the mainstream.3. What does Edward Telles’ research say aboutMexican-Americans?A) They may slowly improve from generation to generation.B) They will do better in terms of educational attainment.C) They will melt into the African-American community.D) They may forever remain poor and underachieving.4. What should be done to help the new immigrants?A) Rid them of their inferiority complex.B) Urge them to adopt American customs.C) Prevent them from being marginalized.D) Teach them standard American English.5. According to the author, the burning issue concerning immigration is_______.A) How to deal with people entering the U.S. without documentsB) How to help immigrants to better fit into American societyC) How to stop illegal immigrants from crossing the borderD) How to limit the number of immigrants to enter the U.S.参考答案:ABDCB文档内容到此结束,欢迎大家下载、修改、丰富并分享给更多有需要的人。
英语四级仔细阅读模拟试题附答案
英语四级仔细阅读模拟试题附答案英语四级仔细阅读模拟试题1:Fried foods have long been frowned upon. Nevertheless, the skillet (长柄平底煎锅) is about our handiest and most useful piece of kitchen equipment. Strong woodcutters and others engaged in active labor requiring 4,000calories per day or more will take approximately one-third of their rations prepared in this fashion. Meat, eggs, and French toast cooked in this way are served in millions of homes daily. Apparently the consumers are not beset with more signs of indigestion than afflicted by those who insist upon broiling, roasting, or boiling. Some years ago one of our most eminent physiologists investigated the digestibility of fried potatoes. He found that the pan variety was more easily broken down for assimilation than when deep fat was employed. The latter, however, dissolved within the alimentary tract ( 消化道 ) more readily than the boiled type. Furthermore, he learned, by watching the progress of the contents of the stomach by means of the fluoroscope (荧光检查仪), that fat actually accelerated the rate of digestion. Now all this is quite in contrast with "authority". Volumes have been written on nutrition, and everywhere the dictum ( 权威意见) has been accepted--no fried edibles of any sort for children. A few will go so tar as to forbid this style of cooking wholly. Now and then an expert will be bold enough to admit that he uses them himself, the absence of discomfort being explained on the ground that he possesses a powerful gastric ( 胃的 )apparatus. We can ofcourse sizzle perfectly good articles to death so that they will be leathery and tough. But thorough heating, in the presence of shortening, is not the awful crime that it has been labeled. Such dishes stimulate rather than retard contractions of the gall bladder. Thus it is that bile ( 胆汁 ) mixes with the nutriment shortly after it leaves the stomach.We dont need to allow our foodstuffs to become oil soaked, but other than that, there seems to be no basis for the widely heralded prohibition against this method. But notions become fixed. The first condemnation probably rose because an "oracle" ( 圣贤) suffered from dyspepsia (消化不良) which he ascribed to some fried item on the menu. The theory spread. Others agreed with him, and after a time the doctrine became incorporated in our textbooks. The belief is now tradition rather than proved fact. It should have been refuted long since, as experience has demonstrated its falsity.56. This passage focuses on__________.A. why the skillet is a handy piece of kitchen equipmentB. the digestibility of fried foodsC. how the experts can mislead the public in the area of food preparationD. why fried foods have long been frowned upon57.

大学英语四级阅读理解模拟试题及答案
大学英语四级阅读理解模拟试题及答案大学英语四级阅读理解模拟试题及答案「篇一」1. C 细节题。
因为Leadville可以为Tabor带来巨富。
这一点不是Leadville得名的原因,因为在文章第二段中,讲到这一点时,提及三个原因:A.因为Tabor成为当地的居民代表人物,B.因为在Leadville有丰富的铅的储藏量。
D.因为Leadville是因为Tabor重要而起的名。
2. D 词汇题。
第二段中grubstake的词义与D所述内容是相同的,即“供给探矿者资金,衣物,食品以及其他物品”。
3. A 细节题。
Tabor第一次真正发财是他为两名矿工提供资助,为此他获得他们矿资源三分之一的股份。
见文章第三段4-9行内容:两名开矿者从Tabor那儿借走价值17美元的物品,作为回报,Tabor获得他们矿资源三分之一股份。
于是两位开矿者在一座山旁的不毛之地开始挖掘,九天之后,发现了银的富矿,于是Tabor又将两人的.股份全买下,这样,银矿属于Tabor一个人所有,这个矿就是后来著名的“匹兹堡”矿。
Tabor用17美元的投资换来了130万美元的收获。
4. B 推断题。
由原文可知泰勃的财产来源是有一定偶然性的,但是毕竟也是基于他开创“grubstake”模式,因为A、D都不对,C更是没有根据,因为他还没有娶第二位夫人这一切就发生了。
分析泰勃的做法,会得出B选项所示的结论。
5. B 推断题。
如果本文是一篇文章的第一部分,那么在文章的第二部分将介绍谁呢?可以从文章第一句分析出来,在Leadville的黄金年代,其多彩的特点当中,Tabor及其第二任妻子Elizabeth McCourt是值得大书特书的,接着,文章都在讲述有关H.A.W.Tabor发家致富的历史,如先买下匹兹堡矿,后又买下Matchless矿,最后成为市长,代理州长,等等,所以涉及到的全是男主人公,因此下边再讲的话,应成为女主人公即Elizabeth McCourt的天地了,她是Tabor的第二任妻子。

While still in its early stages, welfare reform has already been judged a great success in many states—at least in getting people off welfare. Its estimated that more than 2 million people have left the rolls since 1994.In the past four years, welfare rolls in Athens Country have been cut in half. But 70 percent of the people who left in the past tow years took jobs that paid less than $6 an hour. The result: The Athens County poverty rate still remains at more than 30 percent—twice the national average.For advocates (代言人) for the poor, thats an indication much more needs to be done."More people are getting jobs, but its not making their lives any better," says Kathy Lairn, a policy analyst at the Center on Budget and Policy Priorities in Washington.A center analysis of US Census data nationwide found that between 1995 and 1996, a greater percentage of single, female-headedhouseholds were earning money on their own, but that average income for these households actually went down.But for many, the fact that poor people are able to support themselves almost as well without government aid as they did with it is in itself a huge victory."Welfare was a poison. It was a toxin (毒素) that was poisoning the family," says Robert Rector, a welfare-reform policy analyst. "The reform in changing the moral climate in low-income communities. Its beginning to rebuild the work ethic (道德观), which is much more important."Mr. Rector and others argued that once "the habit of dependency is cracked," then the country can make other policy changes aimed at improving living standards.26. From the passage, it can be seen that the author ________.A) believes the reform has reduced the governments burdenB) insists that welfare reform is doing little good for the poorC) is overenthusiastic about the success of welfare reformD) considers welfare reform to be fundamentally successful27. Why arent people enjoying better lives when they have jobs?A) Because many families are divorced.B) Because government aid is now rare.C) Because their wages are low.D) Because the cost of living is rising.28. What is worth noting from the example of Athens County is that ________.A) greater efforts should be made to improve peoples living standardsB) 70 percent of the people there have been employed for two yearsC) 50 percent of the population no longer relies on welfareD) the living standards of most people are going down29. From the passage we know that welfare reform aims at ________.A) saving welfare fundsB) rebuilding the work ethicC) providing more jobsD) cutting government expenses30. According to the passage before the welfare reform was carried out, ________.A) the poverty rate was loverB) average living standards were higherC) the average worker was paid higher wagesD) the poor used to rely on government aid26. D 27. C 28. A 29.B 30. DLong after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decisions that deniedvictory to their team. A researcher was appointed to study the performance of some top referees.The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge.Observers noted down the referees errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的) distance is about 20 meters.There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second.If FIFA, footballs international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues.He also says that FIFAs insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.21. The experiment conducted by the researcher was meant to________.A) review the decisions of referees at the 1998 World CupB) analyse the causes of errors made by football refereesC) set a standard for football refereeingD) reexamine the rules for football refereeing22. The number of refereeing errors in the experimental matches was ________.A) slightly above averageB) higher than in the 1998 World CupC) quite unexpectedD) as high as in a standard match23. The findings of the experiment show that ________.A) errors are more likely when a referee keeps close to the ballB) the farther the referee is from the incident, the fewer the errorsC) the more slowly the referee runs, the more likely will errors occurD) errors are less likely when a referee stays in one spot24. The word "officials" (Line 2, Para. 4) most probably refers to ________.A) the researchers involved in the experimentB) the inspectors of the football tournamentC) the referees of the football tournamentD) the observers at the site of the experiment25. What is one of the possible conclusions of the experiment?A) The ideal retirement age for an experienced football referee is 45.B) Age should not be the chief consideration in choosing a football referee.C) A football referee should be as young and energetic as possible.D) An experienced football referee can do well even when in poor physical condition.21. B 22. C 23. A 24.C 25. B。
