2021年1月大学英语六级阅读理解真题及答案Questions 11 to 15 are based on the following passage:Birds that are literally half-asleep—with one brain hemisphere alert and the other sleeping—control which side of the brain remains awake, according to a new study of sleeping ducks.Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.Decades of studies of bird flocks led researchers to predictextra alertness in the more vulnerable, end-of-the-row sleepers, Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.Also, birds dozing（打盹）at the end of the line resorted to single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Rotating 16 birds through the positions in a four-duck row, the researchers found outer birds half-asleep during some 32 percent of dozing time versus about 12 percent for birds in internal spots.“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness simultaneously in different regions of the brain,” the researchers say.The results provide the best evidence for a long-standing supposition that single-hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He’s seen it in a pair of birds dozing side-by-side in the zoo and in a single pet bird sleeping by mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open. Useful as half-sleeping might be, it’s only been found in birds and such water mammals（哺乳动物）as dolphins, whales, and seals.Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UGLA says he wonders if birds’ half-brain sleep “is just the tip of the iceberg（冰山）”. He speculates that more examples may turn up when we take a closer look at other species.11. A new study on birds’ sleep has revealed that ____________.A) birds can control their half-brain sleep consciouslyB) birds seldom sleep with the whole of their brain at restC) half-brain sleep is found in a wide variety of birdsD) half-brain sleep is characterized by slow brain waves12. According to the passage, birds often half sleep because ______________.A) they have to constantly keep an eye on their companionsB) the two halves of their brain are differently structuredC) they have to watch out for possible attacksD) their brain hemisphere take turns to rest13. The example of a bird sleeping in front of a mirror indicates that _____________.A) birds prefer to sleep in pairs for the sake of securityB) the phenomenon of birds dozing in pairs is widespreadC) a single pet bird enjoys seeing its own reflection in the mirrorD) even an imagined companion gives the bird a sense of security14. While sleeping, some water mammals tend to keep half awake in order to __________.A) avoid being swept away by rapid currentsB) emerge from water now and then to breatheC) alert themselves to the approaching enemyD) be sensitive to the ever-changing environment15. By “just the tip of the iceberg” (Line 2, Para.8), Siegel suggests that ____________.A) half-brain sleep is a phenomenon that could exist among other speciesB) most birds living in cold regions tend to be half sleepersC) the mystery of half-brain sleep is close to being solvedD) half-brain sleep has something to do with icy weatherQuestions 16 to 20 are based on the following passage:A nine-year-old schoolgirl single-handedly cooks up a science-fair experiment that ends up debunking（揭穿．．．的真相）a widely practiced medical treatment. Emily Rosa’s targetwas a practice known as therapeutic（治疗）touch (TT for short), whose advocates manipulate patients’“energy field” to make them feel better and even, say some, to cure them of various ills. Yet Emily’s test shows that these energy fields can’t be detected, even by trained TT practitioners（行医者）. Obviously mindful of the publicity value of the situation, Journal editor George Lundberg appeared on TV to declare, “Age doesn’t matter. It’s good science that matters, and this is good science.”Emily’s mother Linda Rosa, a registered nurse, has been campaigning against TT for nearly a decade. Linda first thought about TT in the late ’80s, when she learned it was on the approved list for continuing nursing education in Colorado. Its 100,000 trained practitioners (48,000 in the U.S.) don’t even touch their patients. Instead, they waved their hands a few inches from the patient’s body, pushing energy fields around until they’re in “balance.”TT advocates say these manipulations can help heal wounds, relieve pain and reduce fever. The claims are taken seriously enough that TT therapists are frequently hired by leading hospitals, at up to $70 an hour, the smooth patients’ energy, sometimes during surgery.Yet Rosa could not find any evidence that it works. To providesuch proof, TT therapists would have to sit down for independent testing—something they haven’t been eager to do, even though James Randi has offered more than $1 million to anyone who can demonstrate the existence of a human energy field. (He’s had one taker so far. She failed.) A skeptic might conclude that TT practitioners are afraid to lay their beliefs on the line. But who could turn down an innocent fourth-grader? Says Emily: “I think they didn’t take me very seriously because I’m a kid.”The experiment was straightforward: 21 TT therapists stuck their hands, palms up, through a screen. Emily held her own hand over one of theirs—left or right—and the practitioners had to say which hand it was. When the results were recorded, they’d done no better than they would have by simply guessing. if there was an energy field, they couldn’t feel it.16. Which of the following is evidence that TT is widely practiced?A) TT has been in existence for decades.B) Many patients were cured by therapeutic touch.C) TT therapists are often employed by leading hospitals.D) More than 100,000 people are undergoing TT treatment.17. Very few TT practitioners responded to the $1 million offerbecause ____________.A) they didn’t take the offer seriouslyB) they didn’t want to risk their careerC) they were unwilling to reveal their secretD) they thought it was not in line with their practice18. The purpose of Emily Rosa’s experiment was ____________.A) to see why TT could work the way it didB) to find out how TT cured patient’s illnessC) to test whether she could sense the human energy fieldD) to test whether a human energy field really existed19. Why did some TT practitioners agree to be the subjects of Emily’s experiment?A) It involved nothing more than mere guessing.B) They thought it was going to be a lot of fun.C) It was more straightforward than other experiments.D) They sensed no harm in a little girl’s experiment.20. What can we learn from the passage?A) Some widely accepted beliefs can be deceiving.B) Solid evidence weighs more than pure theories.C) Little children can be as clever as trained TT practitioners.D) The principle of TT is too profound to understand.Questions 31 to 35 are based on the following passage:What might driving on an automated highway be like? The answer depends on what kind of system is ultimately adopted. Two distinct types are on the drawing board. The first is a special —purpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system: fully automated vehicles would share the road with partially automated or manually driven cars. A special-purpose land system would require more extensive physical modifications to existing highways, but it promises the greatest gains in freeway（高速公路）capacity.Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching the automated highway. If a mixed traffic system was in place, automated driving could begin whenever the driver was on suitably equipped roads. If special-purpose lanes were available, the car could enter them and join existing traffic in two different ways. One method would use a special onramp （入口引道）. As the driver approached the point of entry for the highway, devices installed on the roadside would electronically check the vehicle to determine its destinationand to ascertain that it had the proper automation equipment in good working order. Assuming it passed such tests, the driver would then be guided through a gate and toward an automated lane. In this case, the transition from manual to automated control would take place on the entrance ramp. An alternative technique could employ conventional lanes, which would be shared by automated and regular vehicles. The driver would steer onto the highway and move in normal fashion to a “transition” lane. The vehicle would then shift under computer control onto a lane reserved for automated traffic. (The limitation of these lanes to automated traffic would, presumably, be well respected, because all trespassers（非法进入者）could be swiftly identified by authorities.)Either approach to joining, a lane of automated traffic would harmonize the movement of newly entering vehicles with those already traveling. Automatic control here should allow for smooth merging, without the usual uncertainties and potential for accidents. and once a vehicle had settled into automated travel, the drive would be free to release the wheel, open the morning paper or just relax.21. We learn from the first paragraph that two systems of automated highways __________.A) are being plannedB) are being modifiedC) are now in wide useD) are under construction22. A special-purpose lane system is probably advantageous in that ________________.A) it would require only minor changes to existing highwaysB) it would achieve the greatest highway traffic efficiencyC) it has a lane for both automated and partially automated vehiclesD) it offers more lanes for automated vehicles23. Which of the following is true about driving on an automated highway?A) Vehicles traveling on it are assigned different lanes according to their destinations.B) A car can join existing traffic any time in a mixed lane system.C) The driver should inform his car computer of his destination before driving onto it.D) The driver should share the automated lane with those of regular vehicles.24. We know form the passage that a car can enter aspecial-purpose lane __________.A) by smoothly merging with cars on the conventional laneB) by way of a ramp with electronic control devicesC) through a specially guarded gateD) after all trespassers are identified and removed25. When driving in an automated lane, the driver ___________.A) should harmonize with newly entering carsB) doesn’t have to rely on his computer systemC) should watch out for potential accidentsD) doesn’t have to hold not to the steering wheelQuestions 26 to 30 are based on the following passage:Taking charge of yourself involves putting to rest some very prevalent myths. At the top of the list is the notion that intelligence is measured by your ability to solve complex problems; to read, write and compute at certain levels, and to resolve abstract equations quickly. This vision of intelligence asserts formal education and bookish excellence as the true measures of self-fulfillment. It encourages a kind of intellectual prejudice that has brought with it some discouraging results. We have come to believe that someone who has more educational merit badges, who is very good at some formof school discipline is “intelligent.” Yet mental hospitals are filled with patients who have all of the properly lettered certificates. A truer indicator of intelligence is an effective, happy life lived each day and each present moment of every day. If you are happy, if you live each moment for everything it’s worth, then you are an intelligent person. Problem solving is a useful help to your happiness, but if you know that given your inability to resolve a particular concern you can still choose happiness for yourself, or at a minimum refuse to choose unhappiness, then you are intelligent. You are intelligent because you have the ultimate weapon against the big N. B. D —Nervous Break Down.“Intelligent” people do not have N. B. D.’s because they are in charge of themselves. They know how to choose happiness over depression, because they know how to deal with the problems of their lives. You can begin to think of yourself as truly intelligent on the basis of how you choose to feel in the face of trying circumstances. The life struggles are pretty much the same for each of us. Everyone who is involved with other human beings in any social context has similar difficulties. Disagreements, conflicts and compromises are a part of what it means to be human. Similarly, money, growing old, sickness,deaths, natural disasters and accidents are all events which present problems to virtually all human beings. But some people are able to make it, to avoid immobilizing depression and unhappiness despite such occurrences, while others collapse or have an N. B. D. Those who recognize problems as a human condition and don’t measure happiness by an absence of problems are the most intelligent kind of humans we know; also, the most rare.26. According to the author, the conventional notion of intelligence measured in terms of one’s ability to read, write and compute _____________.A) is a widely held but wrong conceptB) will help eliminate intellectual prejudiceC) is the root of all mental distressD) will contribute to one’s self-fulfillment27. It is implied in the passage that holding a university degree _____________.A) may result in one’s inability to solve complex real-life problemsB) does not indicate one’s ability to write properly worded documentsC) may make one mentally sick and physically weakD) does not mean that one is highly intelligent28. The author thinks that an intelligent person knows _____________.A) how to put up with some very prevalent mythsB) how to find the best way to achieve success in lifeC) how to avoid depression and make his life worthwhileD) how to persuade others to compromise29. In the last paragraph, the author tells us that _____________.A) difficulties are but part of everyone’s lifeB) depression and unhappiness are unavoidable in lifeC) everybody should learn to avoid trying circumstancesD) good feelings can contribute to eventual academic excellence30. According to the passage, what kind of people are rare?A) Those who don’t emphasize bookish excellence in their pursuit of happiness.B) Those who are aware of difficulties in life but know how to avoid unhappiness.C) Those who measure happiness by an absence of problems but seldom suffer form N. B. D.’s.D) Those who are able to secure happiness though having tostruggle against trying circumstances.11. A 12. C 13. D 14. B 15. A 16. D 17. B 18. B 19. C 20. C 21. D 22. D 23. B 24. A 25. B 26.

Words: 1,372Higher Grades Challenge College Application ProcessA) Josh Zalasky should be the kind of college applicant with little to worry about. The high school senior is taking three Advanced Placement courses. Outside the classroom, he，s involved in mock trial, two Jewish youth groups and has a job with a restaurant chain. He，s a National Merit semifinalist and scored in the top ? percent of all students who take the ACT.B) But in the increasingly frenzied world of college admissions, even Zalasky is nervous about his prospects. He doubts he#ll get into the University of Wisconsin, a top choice. The reason: his grades. It$s not that they%re bad. It&s that so many of his classmates are so good. Zalasky’s GPA is nearly an A minus, and yet he ranks only about in the middle of his senior class of 543 at Edina High School outside Minneapolis, Minnesota. That means he will have to find other ways to stand out.C) “It’s extremely difficult,” he said. “I spent all summer writing my essay. We even hired a private tutor to make sure that essay was the best it can be. But even with that, it’s like I*m just kind of leveling the playing field.” Last year, he even considered transferring out of his highly competitive public school, to some place where his grades would look better.D) Some call the phenomenon th at Zalasky’s fighting “grade inflation”—implying the boost is undeserved. Others say students are truly earning their better marks. Regardless, it’s a trend that’s been building for years and may only be accelerating: many students are getting very good grades. So many, in fact, it is getting harder and harder for colleges to use grades as a measuring stick for applicants.E) Extra credit for AP courses, parental lobbying and genuine hard work by the most competitive students have combined to shatter any semblance of a Bell curve, one in which A，s are reserved only for the very best. For example, of the 47,317 applications the University of California, Los Angeles, received for this fall’s freshman class, nearly 23,000 had GPAs of 4.0 or above.F) That’s als o making it harder for the most selective colleges—who often call grades the single most important factor in admissions—to join in a growing movement to lessen the influence of standardized tests.G) “We，re seeing 30, 40 valedictorians at a high school because they don，t want to create these distinctions between students,” said Jess Lord, dean of admission and financial aid at Haverford College in Pennsylvania. “ If we don’t have enough information, there’s a chance we’ll become more heavily reliant on test scores, and that’s a real negative to me.”H) Standardized tests have endured a heap of bad publicity lately, with the SAT raising anger about its expanded length and recent scoring problems. A number of schools have stopped requiring test scores, to much fanfare.I) But lost in the developments is the fact that none of the most selective colleges have dropped the tests. In fact, a national survey shows overall reliance on test scores is higher inadmissions than it was a decade ago. “It’s the only thing w e have to evaluate students that will help us tell how they compare to each other,” said Lee Stetson, dean of admissions at the University of Pennsylvania.J) Grade inflation is hard to measure, and experts，caution numbers are often misleading because standards and scales vary so widely. Different practices of “weighting” GPAs for AP work also play havoc. Still, the trend seems to be showing itself in a variety of ways.K) The average high school GPA increased from 2.68 to 2.94 between 1990 and 2000, according to a federal study. Almost 23 percent of college freshmen in 2005 reported their average grade in high school was an A or better, according to a national survey by UCLA’s Higher Education Research Institute. In 1975, the percentage was about half that.L) GPAs reported by students on surveys when they take the SAT and ACT exams have also risen—and faster than their scores on those tests. That suggests their classroom grades aren’t rising just because students are getting smarter. Not surprisingly, the test-owners say grade inflation shows why testing should be kept: it gives all students an equal chance to shine.M) The problems associated with grade inflation aren’t limited to elite college applicants. More than 70 percent of schools and districts analyzed by an education audit company called SchoolMatch had average GPAs significantly higher than they should have been based on their standardized test scores—including the school systems in Chicago, Illinois, Pittsburgh, Pennsylvania, Denver, Colorado, San Bernardino, California, and Columbus, Ohio. That raises concerns about students graduating from those schools unprepared for college. “They get mixed inwith students from more rigorous schools and they just get blown away,” said SchoolMatch CEO William B ainbridge.N) In Georgia, high school grades rose after the state began awarding HOPE scholarships to students with a 3.0 high school GPA. But the scholarship requires students to keep a 3.0 GPA in college, too, and more than half who received the HOPE in the fall of 1998 and entered the University of Georgia system lost eligibility before earning 30 credits. Next year, Georgia is taking a range of steps to tighten eligibility, including calculating GPA itself rather than relying on schools, and no longer giving extra GPA weight to vaguely labeled “honors” classes.O) Among those who work with students gunning for the more selective colleges, opinions differ as to why there seem to be so many straight-A students. “I think there are more pressures now than there used to be, because 20 or 30 years ago kids with a B plus average got into some of the best colleges in the country,” said William Shain, dean of admissions and financial aid at Bowdoin College in Maine. “It didn，t matter if you had a 3.9 instead of a 3.95. I don，t know if it matters now either, but people are more likely to think it does.”P) Lord, the Haverford dean, sees grade inflation as the outcome of an irrational fear among students to show any slip up—in grades or discipline. In fact, colleges like his are often more interested in students who have overcome failure and challenge than robots who have never been anything less than perfect. “There，s a protection and encouragement of self-esteem that I don’t agree with, but I think it’s a lot of what’s going on here,” he said. “And the college admissions process feeds into that.”Q) Back in Minnesota, Edina may join a growing number ofschools that no longer officially rank students—a move that could help students like Zalasky, who says he was told by Wisconsin his class rank makes him a longshot. “They feel they’re being left behind or not getting into the schools that they’re applying to because of a particular class rank,” says Edina counselor Bill Hicks. “And there is some validity with re spect to some certain schools that use certain formulas.”R) But the colleges most popular with Edina students already know how strong the school is: students’ median verbal and math SAT scores are 1170 out of 1600. Hicks isn’t willing to blame the concentration grades at the top on spineless teachers, or on grade-grubbing by parents and students. Expectations are high, and grades are based on student mastery of the material, not a curve. Wherever teachers place the bar for an A, the students clear it.S) “Everyone here is like, ‘ if I can get a 98 why would I get a 93? said Lavanya Srinivasan, who was ranked third in her Edina class last year. Far from being pushovers, she says, Edina teachers are tougher than those in a course she took at Harvard last summer. Zalasky agrees the students work hard for their high grades. “The mentality of this school is, if you’re not getting straight A，s you’re not doing well,” he said. “There’s just so much pressure on us day in and day out to get straight A’s that everybod y does.” Hicks compares the atmosphere at Edina to the World Series expectations that always surround the superstar lineup of the New York Yankees. “If they don’t win it,” he said, “then it’s failure.”1. Nearly half of the applications that the University of California received this autumn had GPAs of 4.0 or above.2. It，s also harder for the most selective colleges to lessenthe effect of standardized tests.3. More than 30 years ago, about 11.5 percent of college freshmen reported their average grade in high school was an A or better.4. Because of the negative effects of standardized tests recently, a lot of universities have no longer required test scores.5. Some think Zalasky’s improvement unworthy, while others think his high grades win the praise for him.6. Because many of his classmates are so outstanding, Zalasky is nervous about his college application.7. Some colleges would like to admit students who have conquered failure and challenge rather than those who have never been anything less than perfect.8. In the next year, Georgia is taking a series of measures to tighten qualification, including calculating GPA itself and avoiding paying too much attention to vaguely labeled “honors” classes.9. In Zalasky，s opinion, students are put under great pressure to work hard to get straight A"s, or they will be regarded as losers.10. More and more schools no longer officially rank students by grade, which can help students like Zalasky.。

英语六级阅读理解练习和参考答案

英语六级阅读理解练习和参考答案英语六级阅读理解练习和参考答案：Homing pigeons are placed in a training program from about the time they are twenty-eight days of age. They are taught to enter the cage through a trap and to exercise above and around the loft(鸽棚) , and gradually they are taken away for short distances in willow baskets and released. They are then expected to find their way home in the shortest possible time.In their training flights or in actual races, the birds are taken to prearranged distant points and released to find their way back to their own lofts. Once the birds are liberated, their owners, who are standing by at the home lofts, anxiously watch the sky for the return of their entries. Since time is of the essence, the speed with which the birds can be induced to enter the loft trap may make the difference between gaining a win or a second place.The head of a homing pigeon is comparatively small, but its brain is one quarter larger than that of the ordinary pigeon. The homing pigeon is very intelligent and will persevere to the point of stubbornness; some have been known to fly a hundred miles off course to avoid a storm.Some homing pigeon experts claim that this bird is gifted with a form of built-in radar that helps it find its own loft after hours of flight,for hidden under the head feathers are two very sensitive ears, while the sharp, prominent eyes can see great distances in daytime.Why do homing pigeons fly home? They are not unique in this inherent skill; it is found in most migratory birds, in bees, ants, toads, and even turtles, which have been known to travel hundreds of miles to return to their homes. But in the animal world, the homing pigeon alone can be trusted with its freedom and trained to carry out the missions that people demand.21. This passage is mainly about_______.A. homing pigeons and their trainingB. how to buy a homing pigeonC. protection of homing pigeons against the threat of extinctionD. liberation of homing pigeons22. According to the passage, what happens to homing pigeons when they are about a month old?A. They are kept in a trap.B. They enter their first race.C. They begin a training program.D. They get their wings clipped and marked.23. According to the passage, the difference between a homing pigeon and an ordinary one is_______.A. the span of the wingsB. the shape of the eyesC. the texture of the feathersD. the size of the brain24. The author mentions all of the following attributes that enablea homing pigeon toreturn home EXCEPT_______.A. instinctB. air sacsC. sensitive earsD. good eyes25. Why does the author mention bees, ants, toads, and turtles in the last paragraph?A. To describe some unusual kinds of pets.B. To measure distances traveled by various animals.C. To compare their home-finding abilities with those of homing pigeons.D. To interest the reader in learning about other animals.21. A 22. C 23. D 24. B 25. C英语六级阅读理解练习和参考答案：Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some extent our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a persons intelligence are fixed at birth, but whether or not he reachesthose limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(任意的) from the population,it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical (完全相同的) twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth playsa part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.26. Which of these sentences best describes the writers point in Paragraph 1?A. To some extent, intelligence is given at birth.B. Intelligence is developed by the environment.C. Some people are born clever and others born stupid.D. Intelligence is fixed at birth, but is developed by the environment.27. It is suggested in this passage that_______.A. unrelated people are not likely to have different intelligenceB. close relations usually have similar intelligenceC. the closer the blood relationship between people, the more different they are likely to be in intelligenceD. people who live in close contact with each other are not likely to have similar degrees of intelligence28. Brothers and sisters are likely to_______.A. have similar intelligenceB. have different intelligenceC. go to the same universityD. go to the same factory29. In Paragraph 1, the word "surroundings" means_______.A. intelligenceB. lifeC. environmentsD. housing30. The best title for this article would be_______.A. On IntelligenceB. What Intelligence MeansC. We Are Born with IntelligenceD. Environment Plays a Part in Developing Intelligence26. D 27. B 28. A 29. C 30. A。

英语六级考试阅读练习和答案

英语六级考试阅读练习和答案英语六级考试阅读练习和答案:Water problems in the future will become more intense and more complex. Our increasing population will tremendously increase urban wastes, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are poisonous. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever-increasing quantities of agriculture chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.There are two ways by which this pollution problem can be lessened. The first relates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes, or effluents (废料) , to permit the reuse of the water or best reduce pollution upon final disposal.A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient (养料 ) or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents fromother processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste production into marketable byproducts. Other industries have potential economic uses for their waste products.1. The purpose of this passage is_______.A. to warn the reader of the dwindling water supplyB. to explain industrial uses of waterC. to acquaint the reader with water pollution problemsD. to demonstrate various measures to solve the pollution problem2. Which of the following points is not included in the passage?A. Industrial development includes the simplification of complex chemical processes.B. Diluting wastes needs certain amount of water.C. Demands for water will go up along with the expanding population.D. Intensive cultivation of land requires more and more chemicals.3.The reader can conclude that_______.A. countries of the world will work together on pollution problemsB. byproducts from wastes lead to a more prosperous marketplaceC. science is making great progress on increasing water suppliesD. some industries are now making economic use of wastes4.The author gives substance to the passage through the use of_______.A. interviews with authorities in the field of water controlsB. opinion and personal observationsC. definitions which clarify important termsD. strong argument and persuasions5.The words "prior to" (Para. 2) probably mean_______.A. afterB. duringC. beforeD. beyond参考答案：1. C2. A3. D4. B5. C英语六级考试阅读练习和答案:If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on earth will make it necessary for us to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan.Sagan believes that before the earths resources are completely exhausted it will be possible to change the atmosphere of Venus (金星)and so create a new world almost as large as earth itself. The difficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae (藻类) organisms, which can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be bred in conditions similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the carbon dioxide into oxygen and carbon.When the algae have done their work, the atmosphere will become cooler, but before man can set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for men to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.

大学英语六级阅读理解练习与参考答案大学英语六级阅读理解练习与参考答案：As a company executive(总经理) who spent ten years in federal service, I am often asked what I regard as the biggest difference between working for the government and working for a private company. My invariable response is to say that I look back on my time in government as one of the most exciting and challenging experiences of my life. Furthermore, I never worked as hard as when I was a public servant.When I worked for the government, I worked with some of the finest, most competent and most committed people I have ever met.

Good people who leave career government service are striving for highly paid positions in private enterprises.We depend on government to keep this country safe in an uncertain world, to secure justice and domestic order and to solve a host of pressing problems. We need the best possible people performing and overseeing these vital tasks. A high-quality, professional federal service has been a source of national pride for more than a century. But what we have builtup during a hundred years can be lost in less time than we imagine. We cant afford to let this happen.

Charles Deschanel was then the financial minister. He stressed that workmanship and quality were more important than quantity for industrial production. It would be necessary to produce quality goods for the international markets to compete with those produced in other countries. The French economy needed a larger share of international market to balance its import and export trade.French industrial and agricultural production was still inadequate to meet the immediate needs of the people, let alone long-rangeddevelopments. Essential imports had stretched the national credit to the breaking point. Rents were tightly controlled, but the extreme inflation affected general population most severely through the cost of food. Food costs took as much as 80 percent of the workers income. Wages, it is true, had risen. Extensive family allowances and benefits were paid by the state, and there was fulltime and overtime employment. Taken together, these factors enabled the working class to exist but allowed them no sense of security. In this discouraging situation, workmen were willing to work overseas for higher wages.The government was unwilling to let workers leave the country. It was feared that migration of workers would reduce the labor force. The lack of qualified workers might hinder the improvement in the quality of industrial products produced. Qualified workers employed abroad would only increase the quantity of quality goods produced in foreign countries. Also the quantity of quality goods produced in France would not be able to increase as part of its ualified labor force moved to other countries.26. The purpose of the passage is to_______.A. explain the French governments emphasis on quality productsB. discuss Charles Deschanels contribution to the French industrial developmentC. compare the quality of French goods with that of foreign goodsD. show French workmens enthusiasm to seek well-paid jobs in foreign countries27. It can be inferred from the passage that at the time of Rene Coty .A. France was still at the first stage of industrial developmentB. French workers were better paid than the workers in any other European countriesC. the unemployment rate in France was comparatively higher than that in other European countriesD. French workers were able to live better with the increase in their wages28. It is implied in the passage that at that time_______.A. France had a very large share of international marketB. the import and export trade in France was making a successful advanceC. demand and supply in France was barely balancedD. France was experiencing economic depression29. Which of the following is the best indicator of the extreme inflation in France?A. Eighty percent increase in the prices of consumer goods.B. High cost of food.C. High rents for houses.D. Lack of agricultural products.30. Which of the following is NOT mentioned in the passage?A. Rents in France were tightly controlled.B. France was flooding the international market with inferior products.C. French workers were prohibited from going abroad to find jobs.D. The migration of French workers would hinder the improvement of quality in industrial production.26. A 27. A 28. D 29. B 30. B。

2021年6月大学英语六级阅读理解真题及答案_7

2021年6月大学英语六级阅读理解真题及答案Questions 11 to 15 are based on the following passage.We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could mot. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don’t develop sleepdisturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists’ suspicions that the experience or perception of helplessness is one of the most harmful factors in depression. One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the University of Rochester School of Medicine conditioned (使形成条件反射) mice to avoid saccharin (糖精) by simultaneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier conditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.11. Laudenslager’s experiment showed that the immune system of those rats who could turn off the electricity ________.A) was strengthenedB) was not affectedC) was alteredD) was weakened12. According to the passage, the experience of helplessness causes rats to ________.A) try to control unpleasant stimuliB) turn off the electricityC) behave passively in controllable situationsD) become abnormally suspicious13. The reason why the mice in Ader’s experiment avoided saccharin was that ________.A) they disliked its tasteB) it affected their immune systemsC) it led to stomach painsD) they associated it with stomachaches14. The passage tells us that the most probable reason for the death of the mice in Ader’s experiment was that ________.A) they had been weakened psychologically by the saccharinB) the sweetener was poisonous to themC) their immune systems had been altered by the mindD) they had taken too much sweetener during earlier conditioning15. It can be concluded from the passage that the immune systems of animals ________.A) can be weakened by conditioningB) can be suppressed by drug injectionsC) can be affected by frequent doses of saccharinD) can be altered by electric shocksQuestions 16 to 20 are based on the following passage.The destruction of our natural resources and contamination of our food supply continue occur, largely because of the extreme difficulty in affixing (把…固定) legal responsibility on those who continue to treat our environment with reckless abandon (放任). Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been net by lawsuits, personal and industrial denial and long delays—not only in accepting responsibility, but more importantly, in doing something about it.It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative forchange. Where is industry’s and our recognition that protecting mankind’s great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now. We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge. We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion.I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we mustinvestigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.16. We can infer from the first two paragraphs that the industrialists disregard environmental protection chiefly because ________.A) they are unaware of the consequences of what they are doingB) they are reluctant to sacrifice their own economic interestsC) time has not yet come for them to put due emphasis on itD) it is difficult for them to take effective measures17. The main task now facing ecologists, environmental activists and conservationists is ________.A) to prevent pollution by legislation, economic incentives and persuasionB) to arouse public awareness of the importance of environmental protectionC) to take radical measures to control environmental pollutionD) to improve the quality of life by enforcing environmentalstandards18. The word “tunnel-visioned (Line 2, Para. 4) most probably means “________”.A) narrow-mindedB) blind to the factsC) short-sightedD) able to see only one aspect19. Which of the following, according to the author, should play the leading role in the solution of environmental problems?A) Legislation and government intervention.B) The industry’s understanding and support.C) The efforts of environmental health professionals.D) The cooperation of ecologists, environmental activists and conservationists.20. Which of the following is true according to the last paragraph?A) Efforts should be exerted on pollution prevention instead of on remedial measures.B) More money should be spent in order to stop pollution.C) Ordinary citizens have no access to technical information on pollution.D) Environmental degradation will be stopped by the end of thisdecade.Questions 21 to 25 are based on the following passage. British universities, groaning under the burden of a huge increase in student numbers, are warning that the tradition of a free education is at risk. The universities have threatened to impose an admission fee on students to plug a gap in revenue if the government does not act to improve their finances and scrap some public spending cutbacks.The government responded to the universities’threat by setting up the most fundamental review of higher education for a generation, under a non-party troubleshooter (调停人)，Sir Ron Dearing.One in three school-leavers enters higher education, five times the number when the last review took place thirty years ago. Everyone agrees a system that is feeling the strain after rapid expansion needs a lot more money-but there is little hope of getting it from the taxpayer and not much scope for attracting more finance from business.Most colleges believe students should contribute to tuition costs, something that is common elsewhere in the world but would mark a revolutionary change in Britain. Universities want thegovernment to introduce a loan scheme for tuition fees and have suspended their own threatened action for now. They await Dearing’s advice, hoping it will not be too late-some are already reported to be in financial difficulty.As the century nears its end, the whole concept of what a university should be is under the microscope. Experts ponder how much they can use computers instead of classrooms, talk of the need for lifelong learning and refer to students as “consumers.”The Confederation (联盟) of British Industry, the key employers’ organization, wants even more expansion in higher education to help fight competition on world markets from booming Asian economies. But the government has doubts about more expansion. The Times newspaper egress, complaining that quality has suffered as student numbers soared, with close tutorial supervision giving way to “mass production methods more typical of European universities.”21. The chief concern of British universities is ________.A) how to tackle their present financial difficultyB) how to expand the enrollment to meet the needs of enterprisesC) how to improve their educational technologyD) how to put an end to the current tendency of qualitydeterioration22. We can learn from the passage that in Britain ________.A) the government pays dearly for its financial policyB) universities are mainly funded by businessesC) higher education is provided free of chargeD) students are ready to accept loan schemes for tuition23. What was the percentage of high school graduates admitted to universities in Britain thirty years ago?A) 20% or so.B) About 15%.C) Above 30%.D) Below 10%.24. It can be inferred from the passage that ________.A) the British government will be forced to increase its spending on higher educationB) British employers demand an expansion in enrollment at the expense of qualityC) the best way out for British universities is to follow their European counterpartsD) British students will probably have to pay for their higher education in the near future25. Which of the following is the viewpoint of the Timesnewspaper?A) Expansion in enrollment is bound to affect the quality of British higher education.B) British universities should expand their enrollment to meet the needs of industry.C) European universities can better meet the needs of the modern world.D) British universities should help fight competition on world markets.Questions 26 to 30 are based on the following passage: There’s simple premise behind what Larry Myers does for a living: If you can smell it, you can find it.Myers is the founder of Auburn University’s Institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devices—an artificial nose.For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging from the belts of police, arson (纵火) investigators and food-safety inspectors.The technology that they are working in would suggest quite reasonably that, within three to five years, we’ll have someworkable sensors ready to use. Such devices might find wide use in places that attract terrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination.The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too, are the possibilities for abuse; Such machines could determine whether a woman is ovulating (排卵), without a physical exam-or even her knowledge.One of the traditional protectors of American liberty is that is has been impossible to search everyone. That’s getting not to be the case.Artificial biosensors created at Auburn work totally differently from anything ever seen before. Aroma Scan, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those current changes are logged into a computer that sorts out odors based on their electrical signatures. Myers says they expect to load a single fingernail-size chip with thousands of odor receptors (感受器)， enough to createa sensor that’s nearly as sensitive as a dog’s nose.26. Which of the following is within the capacity of the artificial nose being developed?A) Performing physical examinations.B) Locating places which attract terrorists.C) Detecting drugs and water contamination.D) Monitoring food processing.27. A potential problem which might be caused by the use of an artificial nose is ________.A) negligence of public safetyB) an abuse of personal freedomC) a hazard to physical healthD) a threat to individual privacy28. The word “logged“ (Line 5, Para. 7) most probably means”________ “.A) presetB) enteredC) processedD) simulated29. To produce artificial noses for practical use, it is essential ________.A) to develop microchips with thousands of odor receptorsB) to invent chips sensitive to various chemicalsC) to design a computer program to sort out smellsD) to find chemicals that can alter the electrical current passing through30. The author’s attitude towards Larry Myers’ works is ________.A) cautiousB) approvingC) suspiciousD) overenthusiastic11. B12. C13. D14. C15. A16. B17. B18. D19. C20. C21. A22. C23. D24. D25. A26. C27.

大学英语六级阅读理解辅导练习含答案

大学英语六级阅读理解辅导练习含答案The Present Is the Most ImportantShams and delusions are esteemed for soundest truths, while reality is fabulous. If men would steadily observe realities only, and not allow themselves to be deluded, life, to compare it with such things as we know, would be like a fairy tale and the Arabian Nights’ Entertainments. If we respected only what is inevitable and has a right to be , music and poetry would resound along the streets. When we are unhurried and wise, we perceive that only great and worthy things have any permanent and absolute existence, --that petty fears and petty pleasure are but the shadow of reality. This is always exhilarating and sublime. By closing the eyes and slumbering, by consenting to be deceived by shows, men establish and confirm their daily life of routine and habit everywhere, which still is built on purely illusory foundation. Children, who play life, discern its true law and relations more clearly than men, who fail to live worthily, but who think that they are wiserby experience, that is, by failure. I have read in a Hindoo book, that “there was a king’s son, who, being expelled in infancy from hisnative city, was brought up by a forester, and, growing up to maturityin that state, imagined himself to belong to the barbarous race with which be lived. One of his father’s ministers having discovered him, revealed to him what he was, and the misconception of his character was removed, and he knew himself to be a prince. So soul, from the circumstances in which it is placed, mistakes its own character, until the truth is revealed to it by some holy teacher, and then it knowsitself to be Brahme.” We think that that is which appears to be. If a man should give us an account of the realities he beheld, we should not recognize the place in his description. Look at a meeting-house, or a court-house, or a jail, or a shop. Or a dwelling-house, and say whatthat thing really is before a true gaze, and they would all go to pieces in your account of them. Men esteem truth remote, in the outskirts ofthe system, behind the farthest star, before Adam and after the last man. In eternity there is indeed something true and sublime. But all these times and places and occasions are now and here. God himself culminates in the present moment, and will never be more divine in the lapse of all ages. And we are enabled to apprehend at all what is sublime and nobleonly by the perpetual instilling and drenching of the reality that surrounds us. The universe constantly and obediently answers to our conceptions; whether we travel fast or slow, the track is laid for us. Let us spend our lives in conceiving then. The poet or the artist never yet had as fair and noble a design but some of his posterity at least could accomplish it.1. The writ er’s attitude toward the arts is one of[A]. admiration. [B]. indifference. [C]. suspicion. [D]. repulsion2. The author believes that a child.[A]. should practice what the Hindoos preach. [B]. frequently faces vital problems better than grownups do.[C]. hardly ever knows his true origin. [D]. is incapable of appreciating the arts.3. The author is primarily concerned with urging the reader to[A]. look to the future for enlightenment. [B]. appraise the present for its true value.[C]. honor the wisdom of the past ages. [D]. spend more time in leisure activities.4. The passage is primarily concerned with problem of[A]. history and economics. [B]. society and population. [C]. biology and physics. [D]. theology and philosophy.答案ABBD43The statistics I’ve cited and the living examples are all too familiar to you. But what may not be so familiar will be the increasing number of women who are looking actively for advancement of for a new job in your offices. This woman may be equipped with professional skills and perhaps valuable experience, She will not be content to be Executive Assistant to Mr. Seldom Seen of the Assistant Vice President’s Girl Friday, who is the only one who comes in on Saturday.She is the symbol of what I call the Second Wave of Feminism. She is the modern woman who is determined to be.Her forerunner was the radical feminist who interpreted her trapped position as a female as oppression by the master class of men. Men, she believed, had created a domestic, servile role for women in order that men could have the career and the opportunity to participate in making the great decisions of society. Thus the radical feminist held that women through history had been oppressed and dehumanized, mainly because man chose to exploit his wife and the mother of his children. Sometimes it was deliberate exploitation and sometimes it was the innocence of never looking beneath the pretensions of life.The radical feminists found strength in banding together. Coming to recognize each other for the first time, they could explore their own identities, realize their own power, and view the male and his system as the common enemy. The first phases of feminism in the last five years often took on this militant, class-warfare tone. Betty Friedan, Gloria Steinem, Germaine Greer, and many others hammered home their ideas with a persistence that aroused and intrigued many of the brightest and most able women in the country. Consciousness-raising groups allowed women to explore both their identities and their dreams—and the two were often found in direct conflict.What is the stereotyped role of American women? Marriage. A son. Two daughters. Breakfast. Ironing. Lunch. Bowling, maybe a garden club of for the very daring, non-credit courses in ceramics. Perhaps an occasional cocktail party. Dinner. Football or baseball on TV. Each day the same. Never any growth in expectations—unless it is growth because the husband has succeeded. The inevitable question: “Is that all there is to life?”The rapid growth of many feminist organizations attests to the fact that these radical feminists had touched some vital nerves. The magazine “Ms.” was born in the year of the death of the magazine “Life.” But too often the consciousness-raising sessions became endsin themselves. Too often sexism reversed itself and man-hating was encouraged. Many had been with the male chauvinist.It is not difficult, therefore, to detect a trend toward moderation. Consciousness-raising increasingly is regarded as a means to independence and fulfillment, rather than a ceremony of fulfillmentitself. Genuine independence can be realized through competence, through finding a career, through the use of education. Remember that for many decades the education of women was not supposed to be useful.1. What was the main idea of this passage?[A]. The Second Wave of Feminist. [B]. Women’s Independent Spirits. [C]. The Unity of Women. [D]. The Action of Union.2. What was the author’s attitude toward the radical?[A]. He supported it wholeheartedly. [B]. He opposed it strongly.[C]. He disapproved to some extent. [D]. He ignored it completely.3. What does the word “militant” mean?[A]. Aggressive. [B]. Ambitions. [C]. Progressive. [D]. Independent.4, What was t he radical feminist’s view point about the male?[A]. Women were exploited by the male. [B]. Women were independent of the male.[C]. Women’s lives were deprived by the male.[D]. The male were their common enemy.答案ACAD。

大学英语六级阅读理解练习和参考答案

大学英语六级阅读理解练习和参考答案大学英语六级阅读理解练习和参考答案：Once youre prepared for a situation, youre 50 percent of the way toward overcoming nervousness. The other 50 percent is the physical and mental control of nervousness; adjusting your attitude so you have confidence, and control of yourself and your audience.I was in the theater for many years and always went to work with terrible stage fright—until I was in "The King and I". While waiting offstage one night, I saw Yul Brynner, the shows star, pushing in a lunging position against a wall. It looked as though he wanted to knock it down. "This helps me control my nervousness," he explained.I tried it and, sure enough, freed myself from stage fright. Not only that, but pushing the wall seemed to give me a whole new kind of physical energy. Later I discovered that when you push against a wall you contract the muscles that lie just below where your ribs begin to splay (展开).I call this area the "vital triangle".To understand how these muscles work, try this: sit in astraight-backed chair and lean slightly forward. Put your palms together in front of you, your elbows pointing out the sides, your fingertips pointing upward, and push so that you feel pressure in the heels of your palms and under your arms.Say ssssssss, like a hiss. As youre exhaling the s, contract those muscles in the vital triangle as though you were rowing a boat, pulling the oars back and up. The vital triangle should tighten. Relax the muscles at the end of your exhalation, then inhale gently.You can also adjust your attitude to prevent nervousness. What you say to yourself sends a message to your audience. If you tell yourself youre afraid, thats the message your listener receives. So select the attitude you want to communicate. Attitude adjusting is your mental suit of armor against nervousness. If you entertain only positive thoughts, you will be giving out these words: joy and ease, enthusiasm, sincerity and concern, and authority.21. To overcome nervousness, one should_______.A. adjust his attitude as well as make preparation for a gatheringB. ask the audience to give him confidenceC. try not to be knocked down by stage frightD. wait offstage22. "The King and I" should be_______.A. a filmB. a novelC. a playD. a song23.

Yul Brynner pushed the wall in order to_______.A. show the writer how to overcome nervousnessB. pull down the wallC. get physical energyD. overcome his own nervousness25.

One night after a match, he was offered a whisky bottle on the ride home. Tod felt he had to accept,or he would seem like a sissy. He took a swallow, and every time the bottle was passed back to him, he took another swallow. After seven swallows, he passed out. His terrified teammates carried him into his home, and his mother then rushed to the hospital. After his stomach was pumped, Tod learned that his blood alcohol level had been so high that he was lucky not to be in a coma or dead.Although alcohol sometimes causes rapid poisoning, frequently leads to long-term addiction, and always threatens self-control, our society encourages drinking. Many parents, by their example, give children the impression that alcohol is an essential ingredient of social gatherings. Peer pressure turns bachelor parties, fraternity initiations (同仁联谊会入会) , and spring-semester beach vacations into competitions in "getting trashed. " In soap operas, charming characters pour Scotch whiskey from crystal bottle as readily as most people turn on the faucet for tap water. In films and rock videos, trend-setters party in nightclubs and bars. And who can recall a televised baseball or basketball game without a beer commercial? By the age of 21, the average American has been drinking on TV about 75, 000 times. Alcohol ads appear with pounding frequency—in magazines, on billboards, in college newspapers—contributing to a harmful myth about drinking.Part of the myth is that liquor signals professional success. In a mens magazine, one full-page ad for Scotch whiskey shows two men seated in an elegant restaurant. Both are in their thirties, perfectly groomed, and wearing expensive grey suits. The windowsare draped (悬挂) with velvet (天鹅绒) the table with spotless white linen. Each place-setting consists of a long-stemmed water goblet, silver utensils and thick silver plates. On each plate is half-empty cocktail glass. The two men are grinning andshaking hands, as if theyve just concluded a business deal. The caption reads, "The taste of success. "Contrary to what the liquor company would have us believe, drinking is more closely related to lack of success than to achievement. Among students, the heaviest drinkers have the lowest grades. In the work force, alcoholics are frequently late or absent, tend to perform poorly, and often get fired. Although, alcohol abuse occurs in all economic classes, it remains most severe among the poor.Another part of the alcohol myth is that drinking makes you more attractive to the opposite sex. "Hot, hot, hot," one commercials soundtrack(电影配乐) begins, as the camera scans a crowd of college-age beachgoers. Next it follows the curve of a womans leg up to her bare hip and lingers there. She is young, beautiful, wearing a bikini. A young guy, carrying an ice chest (箱子), positions himself near to where she sits. He is tan, muscular. She doesnt show much interest—until he opens the chest and takes out a beer. Now she smiles over at him. He raises his eyebrows and, invitingly, holds up another can. She joins him. This beer, the song concludes, "attracts like no other. "Beer doesnt make anyone sexier. Like all alcohol, it lowers the levels of male hormones in men and of female hormones in women—even when taken in small amounts. In substantial amounts, alcohol can causeinfertility(不生育) in women and impotence (阳萎|) in men. Some alcoholic men develop enlarged breasts, from their increased female hormones.The alcohol myth also creates the illusion that beer and athletics are a perfect combination. One billboard features three high-action images: a baseball player running at top speed, a surfer riding a wave,and a basketball player leaping to make a dunk shot. A particular light beer, the billboard promises, "wont slow you down. "。

英语六级考试阅读练习题和答案

英语六级考试阅读练习题和答案英语六级考试阅读练习题和答案:At some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you dont act on your impulse, but let it pass instead. You know that to commit the action is wrong in some way and that other people will not accept your behavior.Perhaps the most interesting thing about the phenomenon of taboo(禁忌的) behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject.One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is a topic that Americans talk about constantly. Its not taboo to talk about fat; its taboo to be fat. The "in" look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor,and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In animage-conscious society like the U. S. , thin is "in", fat is "out".Its not surprising, then, that millions of Americans have become obsessed (着迷) with staying slim and "in shape". The pursuit of a youthful physical appearance is not, however, the sole reason for Americas obsession with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, peoples bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising every day.1. From the passage we can infer taboo is .A. a strong desire to do something strange or terribleB. a crime committed on impulseC. behavior considered unacceptable in societys eyesD. an unfavorable impression left on other people2.Based on the ideas presented in the passage we can conclude "being fat"_______.A. will always remain a tabooB. is not considered a taboo by most peopleC. has long been a tabooD. may no longer be a taboo some day3.The topic of fat is_______many other taboo subjects.A. the same asB. different fromC. more popular thanD. less often talked about than4.In the U. S. , thin is "in", fat is "out", this means_______.A. thin is "inside", fat is "outside"B. thin is "diligent", fat is "lazy"C. thin is "youthful", fat is "spiritless"D. thin is "fashionable", fat is "unfashionable"5.The main reason the passage gives for why so many Americans are exercising regularly is_______.A. their changed life-styleB. their eagerness to stay thin and youthfulC. their appreciation of the importance of exerciseD. the encouragement they have received from their companies参考答案：1. C2. D3. B4. D5. B英语六级考试阅读练习题和答案:For some time past it has been widely accepted that babies and other creatures learn to do things because certain acts lead to "rewards"; andthere is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological(生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results with no reward except the successful outcome.Papousek began his studies by using milk in the normal way to "reward" the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the childrens responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights—and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many.as three turns to one side.Papouseks light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would " smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.21. According to the author, babies learn to do things which______.A. are directly related to pleasureB. will meet their physical needsC. will bring them a feeling of successD. will satisfy their curiosity22. Papousek noticed in his studies that a baby______.A. would make learned responses when it saw the milkB. would carry out learned movements when it had enough to drinkC. would continue the simple movements without being given milkD. would turn its head to right or left when it had enough to drink23. In Papouseks experiment babies make learned movements of the head in order toA. have the lights turned onB. be rewarded with milkC. please their parentsD. be praised24. The babies would "smile and bubble" at the lights because______.A. the lights were directly related to some basic "drives"B. the sight of the lights was interestingC. they need not turn back to watch the lightsD. they succeeded in "switching on" the lights25. According to Papousek, the pleasure babies get in achieving something is a reflection of______.A. a basic human desire to understand and control the worldB. the satisfaction of certain physiological needsC. their strong desire to solve complex problemsD. a fundamental human urge to display their learned skills 参考答案：21. C 22. C 23. A 24. D 25. A。

Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward.B: Fires, power surges, and floods, theyre 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 over their bad luck. We also shake our heads at the digital consequencesmelted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra of denial: It wont happen to me. Well, the truth is, at some point youll probably have to deal with at least one disaster. Thats 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 shouldnt be. Home computers contain some of our most important information, both business and personal, and making certain ourdata 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 theyre 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 major calamity 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. Thats 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 our burn. Thats because they keep their backups in relatively close to their computers. Their backup disks might not be in the same room as their computerstucked away in a closet or even the garagebut theyre not nearly far enough away should a serious disaster strike. So, its 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 choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldnt add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files ina 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 typesfrom CDs to Jaz 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, its important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a response thats more nuanced thanwholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and agile. 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, youll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, youll 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, its 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 handlefull-scale backups, its also handy for cloning hard drives and facilitating system upgrades. A favorite choice for IT professionals, its 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: Lifes 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, dontwait 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.1. You should take steps to recover from computer disasters so as to minimize their effects.2. For some reason, computer disaster recovery is always ignored by many of us.3. You can bounce back quickly and easily minor computer disasters with the help of a good offsite storage plan and the right tools.4. The most devastating causes of personal computer destruction includes house fires and floods.5. Its necessary for us to back up our systems to some transferable medium and to put it somewhere else.6. You should find a distant place to store your backups after selecting your tools and a suitable medium.7. Not only physical disaster can damage your computer.8. The backup and recovery tools must be flexible enough to deal with various computer crises.9. The quality of your backup tools determines whether you are frustrated or have a peaceful mind when disaster strikes.10. You should prepare for your computer disasters now and again.答案解析1.

大学英语六级考试标准阅读附答案

大学英语六级考试标准阅读附答案Sugar—Friend VS EnemyA) Sugar is everywhere. Its in our drinks, its in our foods, and its hidden in places we neverwould think of. Many would call sugar their friend in time of need, but in fact their so-called “goodfriend” could turn out to be their worst enemy in disguise. Sugar for many is something they mayhave been battling with for a long time. Heres a simple three-step process to help you start to winback the battle for your health.B) The first step is to be aware of what sugar really does to your body. Most people will saythey “know” that they shouldnt have sugar, but they really cant help it. To me that is a lack of trueawareness of what sugar does to oneself. I don+t think many people will say that they want tohurt their body on purpose, but unless they know its really happening they will continue down thatroad. Sugar is slower to impact our health, and it，s that slow destructive process that is themost dangerous. Unfortunately, most people dont know the damage until it has already been done.C) Sugar increases fat storing. Possibly the most important hormone in the body is insulin (胰岛素)，when it comes to weight loss and health. Insulin is the main hormone that we have fullcontrol over daily through our diet and lifestyle. When we eat sugar and it enters into ourbloodstream too quickly, we have a spike in blood sugar levels. Now in times of highactivity we areable to burn it off, but if we are sitting around this is not a good thing. So in response to that highlevel of blood sugar, the body will release more insulin into the bloodstream. Insulin will then takethe excess glucose (葡萄糖)and try to find a place to store it. If your muscles are all full or haveinsulin resistance) then the best place to put the excess glucose is fat cells. When insulin is high,the fat cells are told to shut down any process of releasing stored fat into the blood for burning.With chronic high insulin spikes comes a resistance to it by your cells, leading to more insulinproduction, leading to more fat storing, and more resistance, eventually going down a road ofdiabetes and ill health for the whole body.D) Sugar also disrupts normal brain function. I think most people can relate to mood swingsand energy highs/lows that come after a high sugar meal. Sugar can also be the source of manypeoples increased anxiety and depression. Let us not also forget the kids with ever-increasingattention “disorders” and behavioral issues. Sugar is not helping with that, either. In fact, there havebeen many studies that show when taking sugar out of a kids diet and increasing fat intake, theirattention ability increases, their behavior changes for the better.E) Sugar decreases your overall health and makes you age quicker. Too much sugar will loweryour overall immune system increase destructive inflammation, lead to essential mineraldeficiencies in the body, feed bad bacteria growth in your gut and other wonderful stuff. Aging isjust a fancy word for the body breaking down quicker than it can repair itself, as that is whathappens when we get older. Aging also is accelerated by the increasing risks of all degenerativediseases such as diabetes,osteoporosis, heart disease and cancers. We are all going to get older,but it doesnt mean that we have to “age” quicker.F) The second step is to realize you are in 100% control of your actions. This could be themost underrated yet the most important step, as we are the only person who controls what we putinto our body. Everything starts in what we choose to put in our mouths. Some people may saythey cant control their sugar cravings, but that is already admitting defeat and giving up power tosome “cosmic sugar influence” out there. We can pass on dessert, we dont need to buy a candybar, we can drink water instead of soda, but the choice is ours to make.G) Also many like to call it an “addiction”. This is just another way to give up your own personalpower of choice. While sugar can have “addictive like” qualities, its not something that you own or isa part of you. Fight the battle and you will get over the addictive feelings, they will go away. But ifyou call it an addiction and make it part of you, then it is yours to keep forever. Be free from it, letgo. Take back control and anything is possible.H) The third step is to just live the daily journey one choice at a time. Life is just a series ofpresent moments, and the choices we make in those moments. So let，s just focus on what wecan do right now instead of worrying about what has happened in the past or may or may nothappen in the future. “Now” is all we have and all we need to focus on.I) Choose to eat more natural foods. Choose whole food proteins, healthy fats and naturalsources of carbohydrates. If it wasnt around a thousand years ago or is made by man (and notnature), chances are you dont need it. Note how it says “Choose” above, as it is your choice. Findthehidden sources of sugars and remove them. Sugar is hidden in places such as sauces, ketchup,soups, processed foods, drinks, so called health bars, and more. Become a label reader and seehow much sugar you are consistently putting into your body. Dont fall for the marketing trickeither of “low fat”, because that usually means “more sugar”.1. We are able to lower blood sugar levels by taking part in intense activities.2. If you consider sugar as an addiction and call it something that you own, you won"t get ridof it forever.3. In the authors opinion, the reason why many people can$t help having sugar is that they areunaware of its danger.4. When insulin in the bloodstream is high, fat cells will stop releasing stored fat.5. The author believes that sugar which we called “good friend” in time of need in fact is a hiddenenemy.6. Many studies show that sugar-free diets with more fat can improve childrens attention ability.7. The truth that we get older is that our body breaks down faster than it can be selfrepaired.8. You yield to your addictive feelings, which means you give up your own personal power ofchoice.9. The author believes that taking high sugar meals may result in mood fluctuation.10. To be healthy, what we should do now is to eat natural foods and get rid of the hiddensources of sugars.内容概要糖类食品无处不在，影响了人们的健康。

大学英语六级考试阅读模拟试题Passage OneMedia摘要：本文作者在给出对大众传媒持否定态度的人的意见后，立刻表明了自己的观点，传媒的益处比缺点要多得多。

Every day we are all influenced by the mass media (television, movies, radio, magazines, newspapers and the like). Although some critics of the media claim that these means of communication are used primarily to control our thinking and get us to buy products that we don’t need, the media also contribute to keeping people informed. In other words, while dangers to exist, the benefits of the media far outweigh the disadvantages. Most of the messages brought to viewers, listeners, and readers are designed either to inform or to entertain---and neither of these goals can be considered dangerous or harmful.If consumers of the media could be taught at an early age to examine messages critically---i.e., to think carefully about what is being communicated --- they would be able to take advantage of the information and enjoy the entertainment without being hurt by it. The key to critical thinking is recognizing the purposes of the news or script writers, the advisors, and so on. Are both sides of an issue being presented? Is the amount of the violence and killing shown necessary to the point of a story? Have enough facts about a product being advertised been presented?Furthermore, in a country with a democratic form of government, the people can be kept informed by the mass media. To be able to express their views and vote intelligently, citizens need the opportunity to hear news, opinions, and public affairs programming. Information about current events is presented in depth on publicly funded TV channels and radio stations as well as in newspapers. In addition, the public broadcasting media can help viewers and listeners to complete or further their education. Recent immigrants, for example, can improve their command of English through TV. and radio, and, in addition, some college courses are taught on educational television. Another recognized advantage of the media is that it gives the people the information they need in their daily lives: weather and traffic reports are good examples. While commercials and advertising do not necessarily present accurate information, they do make people aware of the availability of products that could improve their lives. In addition, they create a larger demand for some items, which may lead to a reduction in their price.While the media can be a valuable means of educating the public, when most people turn on the TV set or the radio, they want to be entertained. As a result, most programming consists of movies, plays, music, comedies, game shows, and sports events. Some of these offerings are of low quality, but, on the other hand, many are fun to watch and interesting, written and presented well.Even though the mass media can be misused, most of effects are positive. We are all influenced by television, movies, radio, magazines, and newspapers, and---if we are careful to examine their massages critically--- these can all be of benefit to our lives.Notes:1. 1.script n. 手稿，剧本2. 2.availability n. 可用性，有效性1.1.The main point the author tries to make in this passage is most probably that _______.A)A)advertising is harmful when it presents inaccurate informationB)B)the positive effects of the mass media outweigh the negative onesC)C)people should learn to take advantage of the media’s benefitsD)D)Television is more useful as a means of entertainment than as a means of providinginformation2.2.According to the author, the two main purposes of the mass media are to ______.A)A)control our thinking and get us to buy useless productsB)B)provide people with information and entertainmentC)C)making people aware of the availability of products and create a large demand for someitemsD)D)express the views of t he public and help improve recent immigrants’ English3.3.The author feels that consumers of the mass media should be taught at an early age to ____.A)A)bring their imagination into full play when watching programmes of low qualityB)B)buy products advertised in commercials so that the demand increaseC)C)turn off the TV set when ridiculous program comes onD)D)think critically about the messages brought to them4.4.It can be learned from paragraph 3 that citizens will be in a better position to express theirviews and make their choices if they are _____.A)A)highly educated through TV and radioB)B)well protected by the governmentC)C)highly paid by the employersD)D)well informed by the mass media5.5.Which of the following statements is true according to the passage?A)A)the mass media offers information needed in our daily lives.B)B)Publicly funded broadcasting does not present information about current wents in depth.C)C)Information provided by commercials and advertising is always accurate.D)D)Many TV and radio programmes are not interesting.答案：Passage One:1．1． B. 参照短文第一段，作者在给出对大众传媒持否定态度的人的意见后，立刻表明了自己的观点，传媒的益处比缺点要多得多。

大学英语六级考试阅读题及答案大学英语六级考试阅读精选题及答案通过考级能培养英语学习者的学习兴趣与语言的实际应用能力，建立完整的教学评价与检验体系，下面是小编为大家搜索整理的英语六级辅导练习，希望能给大家带来帮助!Work is a very important part of life in the United States. When the early Protestant immigrants came to this country, they brought the idea that work was the way to God and heaven. This attitude, the Protestant work ethic, still influences America today. Work is not only important for economic benefits, the salary, but also for social and psychological needs, the feeling of doing something for the good of the society. Americans spend most of their lives working, being productive. For most Americans, their work defines them; they are what they do. What happens, then when a person can no longer work?Most Americans stop working at age sixty-five or seventy and retire. Because work is such an important part of life in this culture, retirement can be very difficult. Retirees often feel that they are useless and unproductive. Of course, some people are happy to retire; but leaving one’s job, whatever it is a difficult change, even for those who look forward to retiring. Many retirees do not know how to use their time or they feel lost without jobs.Retirement can also bring financial problems. Many people rely on Social Security checks every month. During their working years, employees contribute a certain percentage of their salaries to the government. When people retire, they receive this money as income. These checks do not provide enough money to live on, however, because prices are increasing very rapidly. Seniorcitizens, those over sixty-five, have to have savings in the bank or other retirement plans to make ends meet. The rate of inflation is forcing prices higher each year; Social Security checks alone cannot cover Medicare (health care) and welfare (general assistance) but many senior citizens have to change their lifestyles after retirement. They have to spend carefully to be sure that they can afford to but food, fuel, and other necessities.Of course, many senior citizens are happy with retirement. They have time to spend with their families or to enjoy their hobbies. Some continue to work part time; others do volunteer work. Some, like those in the Retired Business Executives Association, even help young people to get started in new business. Many retired citizens also belong to “Golden Age” groups. These organizations plan trips and social events. There are many opportunities for retirees.Americans society is only beginning to be concerned about the special physical and emotional needs of its senior citizens. The government is taking steps to ease the problem of limited income. They are building new housing, offering discounts in stores and museums and on buses, and providing other services, such as free courses, food service, and help with housework. Retired citizens are a rapidly growing percentage of the population. This part of the population is very important and we must respond to their needs.

For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions--and vocal green lobbies--the idea seems against nature.[B] In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the U. S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U. S. this year. The genetic is out of the bottle.[C] Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from--and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks?[D] The statistics on population growth and hunger aredisturbing. Last year the world's population reached 6 billion. And by 2050, the UN estimates, it will be probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the world's available cultivable land per person is declining. Arable land has declined steadily since 1960 and will decrease by half over the next 50 years, according to the International Service for the Acquisition of Agri-Biotech Applications ( ISAAA).How can biotech help?[E] Biotechnologists have developed genetically modified rice that is fortified with beta-carotene(胡萝卜素)--which the body converts into vitamin A--and additional iron, and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attribution to pests, drought, poor soil and crop viruses, bacteria or fungi ( 真菌 ).[F] Damage caused by pests is incredible. The European corn borer, for example, destroys 40 million tons of the-world's corn crops annually, about 7% of the total. Incorporating pest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa, yields have increased significantly. So far, fears that genetically modified, pest-resistant crops might kill good insects as well as bad appear unfounded.[G] Viruses often cause massive failure in staple crops in developing countries. Two years ago, Africa lost more than half its cassava (树薯) crop--a key source of calories-to the mosaic virus (花叶病毒).Genetically modified, virus-resistant crops can reduce that damage, as can drought-tolerant seeds in regions where water shortages limit the amount of land under cultivation. Biotech can also help solve the problem of soil that containsexcess aluminum, which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity (毒性) in rice has been identified. Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and help prevent the loss of those crops after they are harvested.[H]Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause ofhunger. Poverty plays the largest role. Today more than 1 billion people around the globe live on less than 1 dollar a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to grow them or if the local population cannot afford to buy the food those farmers produce.[I] Biotech has its own "distribution" problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products won't even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companies are responding to needs of poor countries.[J] More and more biotech research is being carried out in developing countries. But to increase the impact of genetic research on the food production of those countries, there is a need for better collaboration between government agencies--both local and in developed countries--and private biotech firms. The ISAAA, for example, is successfully partnering with the U. S. Agency for International Development, local researches andprivate biotech companies to find and deliver biotech solutions for farmers in developing countries.Will "Franken-foods" feed the world?[K]Biotech is not a panacea ( 治百病的药), but it does promise to transform agriculture in many developing countries. If that promise is not fulfilled, the real losers will be their people, who could suffer for years to come.[L] The world seems increasingly to have been divided into those who favor genetically modified foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering--which can induce plants to grow in poor soils or to produce more nutritious foods―will soon be come an essential tool for helping to feed the world's burgeoning( 迅速发展的) population. Skeptics contend that genetically modified crops could pose unique risks to the environment and to health--risks too troubling to accept placidly. Taking that view, many European countries are restricting the cultivation and importation of genetically modified agricultural products. Much of the debate are concerned about of safety. But what exactly does recent scientific research say about the hazards?[M] Two years ago in Edinburgh, Scotland, eco-vandals stormed a field, crushing canola plants. Last year in Maine, midnight raiders hacked down more than 3,000 experimental poplar trees. And in San Diego, protesters smashed sorghum and sprayed paint over greenhouse walls. This far-flung outrage took aim at genetically modified crops. But the protests backfired: all the destroyed plants were conventionally bred. In each case, activists mistook ordinary plants for genetically modifiedvarieties.[N] It's easy to understand why. In a way, genetically modified crops--now on some 109 million acres of farmland worldwide--are invisible. You can't see, taste or touch a gene inserted into a plant or sense its effects on the environment. You can't tell, just by looking, whether pollen containing a foreign gene can poison butterflies or fertilize plants miles away. That invisibility is precisely what worries people. How, exactly, will genetically modified crops affect the environment--and when will we notice?[O] Advocates of genetically modified or transgenic crops say the plants will benefit the environment by requiring fewer toxic pesticides than conventional crops. But critics fear the potential risks and wonder how big the benefits really are. "We have so many questions about these plants," remarks Guenther Stotzky, a soft microbiologist at New York University. "There's a lot we don't know and need to find out. "As genetically modified crops multiply in the landscape, unprecedented numbers of researchers have started fanning into the fields to get the missing information. Some of their recent findings are reassuring; others suggest a need for vigilance.46. According to the UN's prediction, the population growth from now to 2050 is nearly all in developing countries 译文根据联合国的预测，从现在到2050年的人口增长几乎都集中在发展中家。

大学英语六级考试阅读练习及答案：Of all the continents, the most drastic reduction in wildlife has occurred in North America, where the transition from a rural to a highly industrialized society has been most rapid. Among the victims are birds, mammals, and fish. We will never again see the passenger pigeon or the eastern elk. They have been wiped out. Of many other species, only a few representatives still survive in the wild. The U. S. Department of the Interior has put no fewer than 109 species on the endangered species list. (An endangered species is one with poor prospects for survival and in need of protection. ) This list includes everything from the timber wolf to the whooping crane. Even the bald eagle, our national symbol, is threatened.Animals that kill other game for food are called predators. The predators include the wolf, mountain lion, fox, bobcat, and bear. Attack against these animals began with the arrival of the first European settlers, who wished to protect their livestock. Eventually, a reward was offered to hunters for every predator that was killed. This reward is called a bounty. Ironically, the Federal government is the chief founder of predator-control programs.The settlers also brought in their Old World fears and superstitions concerning predators. Whether preying (捕食) on livestock or not, predators were shot on sight. This attitude continues to this day for coyotes, eagles, foxes, mountain lions, and bobcats, and is largely responsible for placing the eastern timber wolf, grizzly bear, and bald eagle on the endangered species list.Yet every animal, including the predator, has its place in natures grand design. Predators help maintain the health of their prey species by eliminating the diseased, young, old and injured. Predators like the mountain lion and the wolf help to keep the deer herds healthy. Occasional loss of livestock must be weighed against the good these animals do in maintaining the balance of nature.1. In North America, the number of wild animals has reduced most greatly mainly 112because_______.A. the birds, mammals and fish there are most predatorsB. the development there has been at the highest paceC. only a few species still live in the worldD. many species have been put on the endangered species list2. The first European settlers killed predators chiefly in order to_______.A. eat their meatB. protect themselvesC. please the Federal governmentD. protect their livestock3. Some animal species are in danger of disappearing altogether from the earth as a result of_______.A. peoples superstitious attitudeB. peoples dislike of some animals, such as bald eagleC. peoples hunting gamesD. the self-killing of the predators4. Bounty hunters are people who_______.A. take care of wilderness areasB. preserve our wildlifeC. kill meat-eating animals for moneyD. work in the fund of predator-control programs5. According to the writer, even if the meat-eating animals sometimes caused losses of livestock, man should_______.A. estimate the value of predatorsB. compare the losses with the benefits of predatorsC. keep the balance of natureD. raise more livestock1. B2. D3. A4. C5. B大学英语六级考试阅读练习及答案：The greatest recent social changes have been in the lives of women. During the twentieth century there has been a remarkable shortening of the proportion of a womans life spent in caring for the children. A woman marrying at the end of the nineteenth century would probably have been in her middle twenties ? and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, opportunity and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a womans youngest child will be fifteen when she is forty-five years and is likely to take paid work until retirement at sixty. Even while she has the care of children, her work is lightened by household appliances and convenience foods.This important change in womens life-pattern has only recently begun to have its full effect on womens economic position. Even a few years ago most girls left school at the first opportunity, and most of them took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school leaving age is sixteen, many girls stay at school after that age, and though women tend to marry younger, more married women stay at work at least until shortly before their first child is born. Very many more afterwards return to full-or-part-time work. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life, and with both husband and wife sharing more equally in providing the money, and running the home, according to the abilities and interests of each of them.1. According to the passage, it is now quite usual for women to_______.A. stay at home after leaving schoolB. marry men younger than themselvesC. start working again later in lifeD. marry while still at school2. We are told that in an average family about 1900_______.A. many children died before they lived to more than five1. C2. A3. D4. A5. BB. seven or eight children lived to be more than fiveC. the youngest child would be fifteenD. four or five children died when they were five3. Many girls, the passage claims, are now likely to_______.A. give up their jobs for good after they are marriedB. leave school as soon as they canC. marry so that they can get a jobD. continue working until they are going to have a baby4. One reason why a woman today may take a job is that she_______.A. is younger when her children are old enough to look after .themselvesB. does not like children herselfC. need not worry about food for her childrenD. can retire from family responsibilities when she reaches sixty5. Nowadays, a husband tends to_______.A. play a greater part in looking after the childrenB. help his wife by doing much of the houseworkC. feel dissatisfied with his role in the familyD. take a part-time job so that he can help in the home。

英语六级阅读理解练习题和参考答案：Art is considered by many people to be little more than a decorative means of giving pleasure. This is not always the case, however; at times, art may be seen to have a purely functional side as well. Such could be said of the sandpaintings of the Navaho Indians of the American Southwest; these have a medicinal as well as an artistic purpose.According to Navaho traditions, one who suffers from either a mental or a physical illness has in come way disturbed or come in contact with the supernatural—perhaps a certain animal, a ghost, or the dead. To counteract this evil contact, the ill person or one of his relatives will employ a medicine man called a “singer” to perform a healing ceremony which will attract a powerful supernatural being.During the ceremony, which may last from 2 to 9 days, the “singer” will produce a sandpainting on the floor of the Navaho hogan. On the last day of the ceremony, the patient will sit on this sandpainting and the “singer” will rub the ailing parts of the patient’s body with sand from a specific figure in the sandpainting. In this way the patient absorbs the power of that particular supernatural being and becomes strong like it. After the ceremony, the sandpainting is then destroyed and disposed of so its power will not harm anyone.The art of sandpainting is handed down from old “singer” to their students. The material used are easily found in the areas the Navaho inhabit; brown, red, yellow, and white sandstone,which is pulverized by being crushed between 2 stones much as corns is ground into flour. The “singer” holds a small amount of this sand in his hand and lets it flow between his thumb and fore-finger onto a clean, flat surface on the floor. With a steady hand and great patience, he is thus able to create designs of stylized people, snakes and other creatures that have power in the Navaho belief system. The traditional Navaho does not allow reproduction of sandpaintings, since he believes the supernatural powers that taught him the craft have forbidden this; however, such reproductions can in fact be purchased today in tourist shops in Arizona and New Mexico. These are done by either Navaho Indians or by other people who wish to preserve this craft.1.The purpose of the passage is to ___.A.discuss the medical uses of sandpaintings in medieval Europe.B.study the ways Navaho Indians handed down their painting art.C.consider how Navaho “singer” treat their ailments with sandpaintings.D.tell how Navaho Indians apply sandpainting for medical purposes.2.The purpose of a healing ceremony lies in ___.A.pleasing the ghostsB.attracting supernatural powersC.attracting the ghostsD.creating a sandpainting3.The “singer” rubs sand on the patient because ___.A.the patient receives strength from the sandB.it has pharmaceutical valueC.it decorates the patientD.none of the above4.What is used to produce a sandpainting?A.PaintB.Beach sandC.Crushed sandstoneD.Flour5.Which of the following titles will be best suit the passage?A.A New Direction for Medical ResearchB.The Navaho Indians’ SandpaintingC.The Process of Sandpainting CreationD.The Navaho Indians’ Medical History答案：DBACB英语六级阅读理解练习题和参考答案：You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward.These optical illusions occur because the brain is constantly matching its model of reality to signals from the body’s sensors and interpreting what must be happening—that your brain must have moved, not the other; that downward motions is now normal, so a change from it must now be perceived as upward motion.The sensors that make this magic are of two kinds. Each eye contains about 120 million rods, which provide somewhat blurry black and white vision. These are the windows of night vision;once adapted to the dark, they can detect a candle burning ten miles away.Color vision in each eye comes from six to seven million structures called cones. Under ideal conditions, every cone can “see” the entire rainbow spectrum of visible colors, but one type of cone is most sensitive to red, another to green, a third to blue.Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes into seeing a continuous moving picture.Like apparent motion, color vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called “the violet hour.” A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden’s blue flowers.However, look at a white shirt during the reddish light of sunset, and you’ll still see it in its “true” color—white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color of illuminating on both, and adjust accordingly.The eyes can distinguish several million graduations of light and shade of color. Each waking second they flash tens of millions of pieces of information to the brain, which weaves them incessantly into a picture of the world around us.Yet all this is done at the back of each eye by a fabric of sensors, called the retina, about as wide and as thick as a postagestamp. As the Renaissance inventor and artist Leonardo da Vinci wrote in wonder, “Who would believe that so small a space could contain the images of all the universe?”1.Visual illusions often take place when the image of reality is ___.A.matched to six to seven million structures called cones.B.confused in the body’s sensors of both rods and cones.C.interpreted in the brain as what must be the case.D.signaled by about 120 million rods in the eye.2.The visual sensor that is capable of distinguishing shades of color is called ___.A.conesB.color visionC.rodsD.spectrum3.The retina send pulses to the brain ___.A.in short wavelengthsB.as color picturesC.by a ganglion cellD.along the optic nerve.4.Twenty-four still photographs are made into a continuous moving picture just because ___.A.the image we see usually stays longer than it actually appears.B.we see an object in comparison with its surroundings.C.the eyes catch million pieces of information continuously.D.rods and cones send messages 20 to 25 times a second.5.The author’s purpose in writing the passage lies in ___.A.showing that we sometimes are deceived by our own eyes.rming us about the different functions of the eyeorgans.C.regretting that we are too slow in the study of eyes.D.marveling at the great work done by the retina.答案：CADAB。

Cisco, anAmerican network-equipment giant, has invested over many years in the technology needed togenerate such data .Frank Caideroni, the firm's CFO, says that every day its senior executivescan track exactly what orders are coming in from sales teams around the world, and identifyemerging trends in each region and market segment. And at the end of each month, the firmcan get reliable financial results within four hours of closing its books. Most firms have to waitdays or even weeks for such certainty.Admittedly, Cisco's financial results have not made happy reading recently because, incommon with many other large technology companies, it has seen demand for its productsdecline in the downturn. In early February it announced that its fiscal second-quarterrevenues of $ 9.1 billion were 7.5% lower than the same period in 2008 and that its profit hadfallen by 27%, to $1.5 billion.In response to hard times, Cisco plans to cut $1 billion of costs this year by, among otherthings, making use of its own video-conferencing and other communications technologiestoreduce the amount its executives travel. It is also using these facilities to relay information fromemployees on the ground to its senior managers, and to get instructions from Cisco's leadersback out to its 67,000 staff. A rapid exchange of information and instructions is especiallyvaluable if the company wants to alter course in stormy times.If everybody in a company can rapidly grasp what they have to do and how it is changing,they are more likely to get the job done. But some firms are reluctant to share their goals withthe wider world. Unilever, a big Anglo-Dutch consumer-goods group, has decided againstissuing a 2009 financial forecast to investors, arguing that it is difficult to predict what is goingto happen, given the dangerous state of the world economy. "We're not just going to providenumbers for the sake of it," explains James Allison, the company's head of investor relations.Other companies that have decided not to provide annual earnings estimates for 2009include Costco, a big American retailer, and Union Pacific, an American railway company.Some firms, such as Intel, seem to have chosen to take things quarter by quarter. Thegiant chipmaker(芯片制造商) said in January that it would not issue an official forecast for thefirst quarter of 2009 after its fourth-quarter 2008 profit decreased by 90%. Several retailchains have also stopped providing monthly sales estimates because they cannot see what thefuture holds. Retailers, chipmakers and firms in many other industries may have a long waitbefore the economic fog finally lifts.61. What can we learn about Cisco from the passage?A) It will keep a record of the orders from sales teams.B) It cuts $1 billion cost by solely relying on its own technologies.C) Unlike other technology companies, its financial reports are encouraging.D) Only employees can use the video-conferencing to pass information.62. According to the author, the staff can perform better by__________.A) getting instructions from their senior managersB) seizing what to do at hand and what to do nextC) having a financial forecast as a goalD) sharing their goals with others63. What is important in the unstable time ff a company wants to change strategies?A) To issue company's financial reports faster.B) To obtain the up-to-date information of company's business.C) To predict what is going to happen in the future.D) To wait until the economic fog finally lifts.64. The reason Unilever plans not to issue financial forecast in 2009 lies in__________.A) its reluctance to share its goal with othersB) its rapid grasp of changes in the marketsC) the unstable economic situationD) its reduction in the cost of prediction65. What can we know about the giant chipmaker, Intel in the passage?A) It did not issue first-quarter forecast for great decrease in January.B) Inters chain store used to report sales estimates by year.C) Only retailers and chipmakers are greatly influenced.D) Intel's profit was greatly decreased in 2008's last quarter.参考答案：61.A)。

2021年12月六级新题型-长篇阅读理解( 七套)

2021年12月六级新题型-长篇阅读理解（七套）英语六级新题型长篇阅读模拟题一Daylight Saving Time (DST)How and When Did Daylight Saving Time Start?[A] Benjamin Franklin―of “early to bed and early to rise” fame―was apparently the first person to suggest the concept of daylight savings. While serving as U.S. ambassador to France in Paris, Franklin wrote of beingawakened at 6 a.m. and realizing, to his surprise, that the sun would rise far earlier than he usually did. Imaginethe resources that might be saved if he and others rose before noon and burned less midnight oil, Franklin, tongue half in cheek, wrote to a newspaper.[B] It wasn’t until World War I that daylight savings were realized on a grand scale. Germany was the first state to adopt the time changes, to reduce artificial lighting and thereby save coal for the war effort. Friends and foes soon followed suit. In the U.S. a federal law standardized the yearly start and end of daylight saving time in 1918―for the states that chose to observe it.[C ] During World War II the U.S. made daylight saving time mandatory^ 强制的)for the whole country, as a way to save wartime resources. Between February 9, 1942, and September 30, 1945, the government took it a step further. During this period daylight saving time was observed year-round, essentially making it the new standard time, if only for a few years. Many years later, the Energy Policy Act of 2021 was enacted, mandating a controversial month-long extension of daylight saving time, starting in 2021.Daylight Saving Time: Energy Saver or Just Time Suck?[D ] In recent years several studies have suggested that daylight savingt ime doesn’t actually save energy―and might even result in a net loss. Environmental economist Hendrik Wolff, of the University of Washington, co-authored a paper that studied Australian power-use data when parts of the country extended daylight saving time for the 2000 Sydney Olympics and others did not. The researchers found that the practice reduced lighting andelectricity consumption in the evening but increased energy use in the now dark mornings―wiping out the evening gains. That’s because the extra h ourthat daylight saving time adds in the evening is a hotter hour. “So if people get home an hour earlier in a warmer house, they turn on their air conditioning,” the University of Washington’s Wolff said.[ E] But other studies do show energy gains. In an October 2021 daylight saving time report to Congress, mandated by the same 2021 energy act that extended daylight saving time, the U.S. Department of Energy asserted that springing forward does save energy. Extended daylight saving time saved 1.3 terawatt (太瓦)hours of electricity. That figure suggests that daylight saving time reduces annual U.S. electricity consumption by 0.03 percent and overall energy consumption by 0.02 percent. While those percentages seem small, they could represent significant savings because of the nation’s enormous total energy use.[F] What*s more, savings in some regions are apparently greater than in others. California, for instance, appears to benefit most from daylight saving time―perhaps1because its relatively mild weather encourages people to stay outdoors later. The Energy Department report found that daylight saving time resultedin an energy savings of one percent daily in the state.[G] But Wolff, one of many scholars who contributed to the federal report, suggested that the numbers were subject to statistical variability (变化)and shouldn’t be taken as hard facts. And daylight savings, energy gains in the U.S. largely depend on your location in relation to the Mason-Dixon Line, Wolff said. “The North might be a slight winner, because the North doesn’t have as much air conditioning,” he said. “But the South is a definite loser in terms of energy consumption. The South has more energy consumption under daylight saving.” Daylight Saving Time: Healt hy or Harmful?[ H] For decades advocates of daylight savings have argued that, energy savings or no, daylight saving time boosts health by encouraging active lifestyles―a claim Wolff and colleagues are currently putting to the test. “In a nationwide A merican time-use study, we’re clearly seeing that, at the time of daylight saving time extension inthe spring, television watching is substantially reduced and outdoor behaviors like jogging, walking, or going tothe park are substantially increas ed,” Wolff said. “That’s remarkable, because of course the total amount of daylight in a given day is the same. ”[I] But others warn of ill effects. Till Roenneberg, a university professor in Munich (慕尼,黑),Germany, said his studies show that our circadian (生理节奏的)body clocks―set by light and darkness―never adjust to gaining an “extra” hour of sunlight to the end of the day during daylight saving time.[J ] One reason so many people in the developed world are chronically (长期地）overtired, he said, is t hat they suffer from “social jet lag. ” In other words, their optimal circadian sleep periods don\accord with their actual sleep schedules. Shifting daylight from morning to evening only increases this lag, he said. “Light doesn’t do the same things to the body in the morning and the evening. More light in the morning would advance the body clock, and that would be good. But more light in the evening would even further delay the body clock. ”[K] Other research hints at even more serious health risks. A 2021 study concluded that, at least in Sweden, heart attack risks go up in the days just after the spring time change. “The most likely explanation to our findings is disturbed sleep and disruption of biological rhythms,” One expert told National Geographic News via email.Daylight Savings! Lovers and Haters[L] With verdicts (定论)on the benefits, or costs, of daylight savings so split, it may be no surprise that the yearly time changes inspire polarized reactions. In the U.K., for instance, the Lig hter Later movement―part of10:10, a group advocating cutting carbon emissions―argues for a sort of extreme daylight savings. First, they say, move standard time forward an hour, then keep observing daylight saving time as usual―adding two hours of evening daylight to what we currently consider standard time. The folks behind Standardtime .com, on the other hand, want to abolish daylight2saving time altogether, calling energy-efficiency claims “unproven. ”[M] National telephone surveys by Rasmussen Reports from spring 2021 and fall 2021 deliver the same answer. Most people just “don’t think the time change is worth the hassle (麻烦洽勺事）.” Forty-seven percent agreed with that statement, while only 40 percent disagreed. But Seize the Daylight author David Prerau said his research on daylight saving time suggests most people are fond of it. “I think if you ask most people if they enjoy having an extra hour of daylight in the evening eight months a year, the response would be pretty positive.”46. Daylight savings，energy gains might be various due to different climates. 47. Disturbed sleep and disruption of biological rhythms may be the best explanation to higher heart attack risks in the days after the spring time change.48. A research indicated that DST might not save energy by increasing energy use in the dark mornings, though it reduced lighting and electricity consumption in the evening.49. Germany took the lead to save wartime resources by adopting the time changes and reducing artificial lighting.50.
