Gulf Wracked By Katrina's Latest Legacy-Disease, Poisons, MoldA month after Hurricane Katrina tore through the U.S. Gulf Coast, medical experts are now struggling with the latest crisis in the region; contamination(污染). Katrina left New Orleans and other communities tainted with oil, sewage, and Protection Agency (EPA) s ays.The pollution, combined with the lack of regular medical services in the region, has raised serious questions about the safety of New Orleans and other coastal towns as people longing for home begin to go back.I don't think New Orleans is safe for people to return to, from a public health and environmental health standpoint, said Miriam Aschkenasy, an environmental health expert working with Oxfam America in the region.Much of the contamination rests in the brown, filmy sediment(沉淀物) left behind by Katrina's polluted floodwaters.Recent EPA tests of the sediment confirmed high levels of E. coli bacteria, oil andgas chemicals, and lead, as well as varying quantities of arsenic.The health risks posed by the sediment are immediate, experts say, because the sludge(淤泥) is nearly impossible for returning residents to avoid. In New Orleans, it covers e very s urface that was flooded, from cars a nd n ow-dead lawns to t he e ntire contents of flooded homes, stores, hospitals, and schools.When p eople c ome b ack, t hey a re e xposed t o t he s ediment, s aid W ilma S ubra, a chemist from New Iberia, Louisiana, who is analyzing the sediment. It's in their yards and h ouses. Old Pollution ResurfacingPlaquemines Parish, a rural county on the peninsula south of New Orleans, is now covered with even more toxic sediment than it was two weeks ago, thanks to Hurricane R ita. Six inches up to one foot (15 to 30 centimeters) of sludge, Subra2021级大学英语四级模拟试卷reported.1Much o f t he s ludge i n P laquemines i s t he p roduct o f n earby b ayous a nd b ay bottoms, where sediment was lifted up by Katrina's and Rita's storm surges.The sediment has been polluted over the years with industrial chemicals and heavy metals, said Subra, who tested the sediment for the Southern Mutual Help Association, a nonprofit organization in New Iberia, Louisiana.These water bodies have received industrial wastes for decades, she said. This material h as t oxic c hemicals, metals, and o rganic p etrochemicals(石化产品). Matters have only been made worse by multiple oil spills caused by Katrina and Rita. According to the U.S. Coast Guard, 11 oil spills have occurred in southern Louisiana, t otaling 7.4 m illion g allons (28 m illion l iters) o f o il, m ost o f w hich h as b een contained.Bacteria levels are also especially high in the Plaquemines sludge, said Rodney Mallett, spokesperson for the Louisiana Department of Environmental Quality.The sewage treatment plants were underwater, he explained. Between the animal waste and the human waste, you've got a lot of bacteria.Protection KitsHealth a nd e nvironmental a gencies a re a dvising p eople t o a void c ontact w ith t he sludge. They recommend that people wear gloves, goggles, and dust masks, and that they wash promptly if exposure occurs.EPA officials are directing people to its Web site () to inform themselves ofthe contamination risks.But most people returning to the area don't have computers to get that information, said Erik Olson, an attorney for the Natural Resources Defense Council,an environmental a dvocacy group. If you [do] read the Web site, he added, you practically have to have a degree in chemistry to understand it.To b etter i nform p eople o f h ealth r isks, t he S outhern M utual H elp A ssociation a nd Oxfam America are developing a program to give every returning resident a protective kit.Each kit would contain waterproof suits, goggles(风镜), shoe covers, and masks, along with i nformation about potential h azards, Volunteers would g ive out t he kits a tthe security checkpoints that now stand at the major entrances to affected cities.The groups have made a hundred demonstration kits, which cost about $100 (U.S.) each to produce, and have shown them to state leaders in Louisiana.The g overnor i s r eally i n f avor o f t his, S ubra s aid.

You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the center. Passage OneQuestion 57 to 61 are based on the following passage.Among all the animals, the ape is most like human beings. Both people and apes have the similar brain structure, the similar nerve system, and the similar kind of blood.There are four kinds of apes: the chimpanzee(黑猩猩), the orangutan(猩猩), the gorilla(大猩4猩), and the gibbon(长臂猿). They live in the deep forests and warm tropical regions of Africa and of Southeast Asia, including Indonesia.All apes are covered with brown, reddish-brown, or black hair everywhere on their bodies e xcept t heir f aces, f eet, a nd h ands. T heir h ands e ach h ave f our f ingers a nd a thumb that helps them grip things the way our thumbs help us. But they also have a thumb on each foot instead of a big toe. Thus they can hold things with their feet also. Having short, weak legs, apes do not walk on the ground very much. However, their arms are very strong. This enables them to swing from branches and travel very quickly from tree to tree.These a nimals l ive i n s mall f amily g roups t hat m ove f rom p lace t o p lace i n s earch o f vegetables and fruits. They also eat eggs, small animals, nuts, and insects. When they are tired, they build nests in the trees. But they rarely sleep there for more than a night or two. Then they move on to look for more food.There are some differences among the following three kids of apes. The gibbon is never m ore t han t hree f eet h igh and w eight o nly about f ourteen p ounds. The g orilla grows to be six feet tall and weigh up to 600 pounds.

Almost eleven percent of the students aged 3~21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one or more of the following ways: mentally retarded(进展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, or other health impairments. The education of these handicapped children is rewarding but challenging.A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, and indefatigable(孜孜不倦的) consistency o n t he p art o f t he t eacher i s f requently n ecessary.

Repetition of any videodisc lesson can continue endlessly, and designers can assure absolute consistency within a program. Most important, according to special educator William Healey of the University of Arizona, is that videodisc adds an extradimension of realism for children who need graphic representations.Healey explained that deaf and mentally retarded children especially have difficulty grasping figurative(比方的)language and higher-order language concepts. He believes that for special education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken for granted bynon-handicapped persons. Complex figurative language forms such as idioms and metaphors come most readily to mind as being difficult for handicapped learners. 62. The special education mentioned in the text is mainly concerned with.[A] genius students from day-care centers to colleges[B] students who are fond of computer video games[C] teachers of language in the University of Arizona[D] students who are either mentally or physically disabled63. A videodisc courseware is beneficial to those who have study difficulties because .[A] its fancy design is very attractive[B] it allows the user to go back to where he wants to restudy[C] the content of it is healthy and promising[D] it is developed by university professors64. According to Professor Healey, we may infer that mentally retarded children perhaps .[A] need graphic representations in order to understand higher-order language concepts[B] are g ood a t s tudying E nglish i dioms b ut o ften f ail t o g rasp h igher-orderlanguage concepts[C] are not very patient with videodisc which helps them to understand the world concepts[D] tend t o b e deaf a s well and have difficulty learning the simple concept b eforeand after65.

The following two situations can enable us to clearly see how a positive attitude helps us cope with unpleasant things. Take English learning for example. In our effort to grasp English, mistakes are unavoidable.

In1911he had made the longest flight to date,and that over open sea90miles from Key West to Havana.He won the first cross country race in Canada40miles from Hamilton to Toronto—and he transmitted the first radio message from aircraft.When World WarⅡcame,McCurdy took on board supervisory authority for Canadian aircraft production by serving with the government in various senior positions.Following World WarⅡ,McCurdy was honored by being made lieutenant governorof Nova Scotia where he made Canada’s first historic flight.He now lives in Montreal with a summer home in Baddeck,site of his first flight.31.According to the pasage,which of the following statements is NOT true about McCurdy?A.He was a Canadian.B.He is regarded as the symbol of Canadian aviation and aircraft industry.C.He is the first man to finish a figure eight in the air.D.He now lives in Baddeck.32.The“Silver Dart”is____.A.the name of a weaponB.a plane bought by McCurdyC.the nickname of a famous Canadian pilotD.a plane designed by McCurdy33.McCurdy is NOT the first one to____.A.fly in CanadaB.pilot a flying boatC.fly from Key West to TorontoD.fly to Mexico34.Nowadays,McCurdy____.A.lives in Montreal in summerB.is the lieutenant governor of Nova ScotiaC.is still very active and energeticD.is the government’s counsellor35.The best title for this passage is____.A.How McCurdy Became a Famous Canadian PilotB.McCurdy’s Legendary ExperienceC.McCurdy and the Canandian AviationD.McCurdy—the Symbol of American Aviation and the Aircraft IndustryQuestions36to40are based on the following passage:The oldest and simplest method,then of describing differences in personality was to classify people according to types,and such a system is called a Typology.A famous example of this method was set forth in Greece about the year400BC.A physician named Hippocrates theorized that there were four fluids,or humors,in the body. Corresponding to each humor,he believed,there existed a definite type of personality.The four humors were blood,yellow bile,black bile,and phlegm.A person in whom all four humors were in perfect balance had a harmonious personality.If a person had too much blood,he was called sanguine(血红色),or cheerful and optimistic.Someone with too much yellow bile was choleric, or irritable and easily angered.Too much black bile made a person melancholy,or depressed and pessimistic.An oversupply of phlegm caused a human being to be phlegmatic,or slow and unfeeling. Scientists have long since discarded Hippocrates’fluid theory.But the names of the humors, corresponding to these temperaments,have survived and are still useful,to some extent,in describing personality.Other features of people,such as their faces and physics,have also been used to classify personality.Today,however,personality theories and classifications may also include factors such as heredity(遗传特征),the environment,intelligence,and emotional needs.Psychology, biology,and sociology are involved in these theories.Because of the complexity of human personality,present day theories are often very different from one another.Psychologists vary in their ideas about what is most important in determining personality.36.According to Hippocrates’fluid theory,a man with too much phlegm will be____.A.optimisticB.easily angeredC.unexcitableD.pessimistic37.The main idea of this passage is about____.A.the complicated factors in determining one’s personalityB.Hippocrates’fluid theory and its developmentC.the past and today of personality classifications and theoriesD.different personalities and their details38.At present,psychologists____.A.have common opinion about personality theories

personalities39.The third paragraph mainly talks about____.A.Hippocrates’fluid theoryB.scientists’points of view on Hippocrutes’fluid theoryC.Hippocrates’fluid theory and its fateD.defects in

大学英语四级备考模拟题及答案

大学英语四级备考模拟题及答案2016年大学英语四级备考模拟题及答案Part II Reading Comprehension (35 minutes)Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage OneQuestions 21 to 25 are based on the following passage.There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the finding of science.Another distinction between science and technology has to do with the progress in each.Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people's likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or anger people-as did Darwin's theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But hardly so with technology; we do not have the choice of refusing to hearthe sonic boom produced by a supersonic aircraft flying overhead; we do not have the option of refusing to breathe polluted air; and we do not have the option of living in a non-atomic age. Unlike science progress, technology must be measured in terms of the human factor. The legitimate purpose of technology is to serve people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves. Technology must be humanistic if it is to lead to a better world.21. The difference between science and technology lies in that _____.A) the former provides answers to theoretical questions while the latter to practical problemsB) the former seeks to comprehend the universe while the latter helps change the material worldC) the former aims to discover the inter-connections of facts and the rules that explain them while the latter, to discover new designs and ways of making the things we use in our daily lifeD) all of the above22. Which of the following may be representative of science?A) The improvement of people's life.B) The theory of people's life.C) Farming tools.D) Mass production.23. According to the author, scientific theories _____.A) must be strictly objectiveB) usually take into consideration people's likes and dislikesC) should conform to popular opinionsD) always appear in perfect and finished forms24. The author states that technology itself _____.A) is responsible for widespread pollution and resource exhaustionB) should serve those who wish to gain advantage for themselvesC) will lead to a better world if put to wise useD) will inevitably be for bad purpose25. The tone of the author in this passage is _____.A) positive B) negative C) factual D) critical Passage TwoQuestions 26 to 30 are based on the following passage.Americans have always been ambivalent in their attitudes toward education. On the one hand, free and universal public education was seen as necessary in a democracy, for how else would citizens learn how to govern themselves in a responsible way? On the other hand, America was always a country that offered financial opportunities for which education was not needed: on the road from rags to riches, schooling-beyond the basics of reading, writing, and arithmetic-was an unnecessary detour.Even today, it is still possible for people to achieve financial success without much education, but the number of situations in which this is possible is decreasing. In today's more complex world, the opportunities for financial success is closely related to the need for education, especially higher education.Our society is rapidly becoming one whose chief product is information, and dealing with this information requires more and more specialized education. In other words, we grow up learning more and more about fewer and fewer subjects.In the future, this trend is likely to continue. Tomorrow's world will be even more complex than today's world, and, to manage this complexity, even more specialized education will beneeded.26. The topic treated in this passage is _____.A) education in general B) Americans' attitudesC) higher education D) American education27. Americans' attitudes toward education have always been _____.A) certain B) contradictory C) ambitious D) unclear28. Today, financial success is closely related to the need for _____.A) higher education B) public education C) responsible citizens D) learning the basics29. It can be inferred from the third paragraph that _____.A) information is our only productB) education in the future will be specializedC) we are entering an age of informationD) we are living in an age of information30. Which of the following is the best title for the passage?A) The History of American Education.B) The Need for Specialized Education.C) The Future of the American Educational System.D) Attitudes toward American Education. Passage ThreeQuestions 31 to 35 are based on the following passage.A growing world population and the discoveries of science may alter this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in consequence the population of the world is steadily increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.When numbers rise the extra mouths must be fed. New landsmust be brought under cultivation, or land already farmed made to yield larger crops. In some areas the accessible land is so intensively cultivated that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too tiny to allow for much improvement in farming methods. Were a large part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods. There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New strains of crops are being developed which will thrive in unfavorable climates: there are now farms beyond the Arctic Circle in Siberia and North America; irrigation and dry-farming methods bring arid lands under the plough, dams hold back the waters of great rivers to ensure water for the fields in all seasons and to provide electric power for new industries; industrial chemistry provides fertilizers to suit particular soils; aeroplanes spray crops to destroy locusts and many plant diseases. Every year some new means is devised to increase or to protect the food of the world.31. The author says that the world population is growing because _____.A) there are many rich valleys and fertile plainsB) the pattern of distribution is being alteredC) people are living longerD) new land is being brought under cultivation32. The author says that in densely populated areas the land might be more productively farmed if _____.A) the plots were subdividedB) a large part of the people moved to a different part of the countryC) industrial methods were used in farmingD) the units of land were made much larger33. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.A) producing new strains of cropsB) irrigation and dry-farming methodsC) providing fertilizersD) destroying pests and disease34. Which of these words is nearest in meaning to the word "strains"?A) types B) sizes C) seeds D) harvests35. The author's main purpose is to _____.A) argue for a belief B) describe a phenomenonC) entertain D) propose a conclusion Passage FourQuestions 36 to 40 are based on the following passage.For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to "rewards"; and there 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 in the world 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 drinkwould refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's 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.Papousek's 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.36. According to the author, babies learn to do things which .A) are directly related to pleasure B) will meet their physical needsC) will bring them a feeling of success D) will satisfy their curiosity37. 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 drink38. In Papousek's experiment babies make learned movements of the head in order to .A) have the lights turned onB) be rewarded with milkC) please their parentsD) be praised39. 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 lights40. 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。

First, a human “guinea pig”is tested using a regular tool. Measurements are taken of the amount of work done, and the buildup of heat in the body. Twisted joints and stretched muscles can not perform as well, it has been found, as joints and muscles in their normal positions. The same person is then tested again, using a tool designed according to the suggestions made by Dr. Tichauer. All these tests have shown the great improvement of the new designs over the old.One of the electronic instruments used by Dr. Tichauer, the myograph （肌动记器）, makes visible through electrical signals the work done by human muscle.Another machine measures any dangerous features of tools, thus proving information upon which to base a new design. One conclusion of tests made with this machine is that a tripod stepladder is more stable and safer to use than one with four legs. This work has attracted the attention of efficiency experts and time-and-motion-study engineer, but its value goes far beyond that. Dr. Tichauer’s first thought is for the health of the tool user. With the repeated use of the same tool all day long on production lines and in other jobs, even light manual work can put a heavy stress on one small area of the body. In time, such stress can cause a disabling disease. Furthermore, muscle fatigue is a serious safety hazard.Efficiency is the by-product of comfort, Dr. Tichauer believes, and his new designs for traditional tools have proved his point.21. What are involved in the design of a new tool according to the passage?A) Electronic instruments and a regular tool.B) A human “guinea pig”and a regular tool.C) Electronic instruments and a human “guinea pig”.D) Electronic instruments, a human “guinea pig”and a regular tool.22. From the passage we know that joints and muscles perform best when __________________.A) they are twisted and stretchedB) they are in their normal positionsC) they are tested with a human “guinea pig”D) they are tested with electronic instruments23. A “myograph”(Para. 2, Line 1) is an electronic instrument that ________________.A) is able to design new toolsB) measures the amount of energy usedC) enable people to see the muscular movementsD) visualizes electrical signals24. It can be inferred from the passage that ________________.A) a stepladder used to have four legs.B) it is dangerous to use toolsC) a tripod is safer in a tool designD) workers are safer on production lines25. Dr. Tichauer started his experiments initially to _________________.A) improve efficiencyB) increase productionC) reduce work loadD) improve comfortQuestions 26 to 30 are based on the following passage:More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can reap big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment.It’s easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers.Of course, we have no statistics on crimes that go undetected. But it’s disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck.Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met.Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled (诈骗) the most confidential （保密）records right under the noses of the company’s executives, accountants, and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.26. It can be concluded from the passage that _______________.A) it is still impossible to detect computer crimes todayB) people commit computer crimes at the request of their companyC) computer criminals escape punishment because they can’t be detectedD) computer crimes are the most serious problem in the operation of financial institutions27. It is implied in the third paragraph that _________________.A) most computer criminals who are caught blame their bad luckB) the rapid increase of computer crimes is a troublesome problemC) most computer criminals are smart enough to cover up their crimesD) many more computer crimes go undetected that are discovered28. Which of the following statements is mentioned in the passage?A) A strict law against computer crimes must be enforcedB) Companies usually hesitate to uncover computer crimes to protect their reputationC) Companies will guard against computer crimes to protect their reputationD) Companies need to impose restrictions on confidential information29. What may happen to computer criminals once they are caught?A) With a bad reputation they can hardly find another job.B) They may walk away and easily find another job.C) They will be denied access to confidential recordsD) They must leave the country to go to jail.30. The passage is mainly about _________________.A) why computer criminals are often able to escape punishmentB) why computer crimes are difficult to detect by systematic inspectionsC) how computer criminals mange to get good recommendations from their former employersD) why computer crimes can’t be eliminatedQuestions 31 to 35 are based on the following passage.In a family where the roles of men and women are not sharply separated and where many household tasks are shared to a greater or lesser extent, notions of male superiority are hard to maintain. The pattern of sharing in tasks and indecision makes for equality and this in turn leads to further sharing. In such a home, the growing boy and girl learn to accept equality more easily than did their parents and to prepare more fully for participation in a world characterized by cooperation rather than by the “battle of the sexes”.If the process goes too far and man’s role is regarded as less important –and that has happened in some cases – we are as badly off as before, only in reverse.It is time to reassess the role of the man in the American family. We are getting a little tired of “Momism”– but we don’t want to exchange it for a “neo-Popism”. What we need, rather, is the recognition that bringing up children involves a partnership of equals. There are signs that psychiatrists, psychologists, social workers, and specialists on the family are becoming more aware of the part men play and that they have decided that women should not receive all the credit – nor the blame. We have almost given up saying that a woman’s place is in the home. We are beginning, however, to analyse man’s place in the home and to insist that he does have a place in it. Nor is that place irrelevant to the healthy development of the child.The family is a co-operative enterprise for which it is difficult to lay down rules, because each family needs to work out itsown ways for solving its own problems.Excessive authoritarianism（命令主义）has unhappy consequences, whether it wears skirts or trousers, and the ideal of equal rights and equal responsibilities is pertinent （相关的，切题的）not only to a healthy democracy, but also to a healthy family.31. The ideal of equal rights and equal responsibilities is _________________.A) fundamental to a sound democracyB) not pertinent to healthy family lifeC) responsible for MomismD) what we have almost given up32. The danger in the sharing of household tasks by the mother and the father is that ___________.A) the role of the father may become an inferior one’B) the role of the mother may become an inferior oneC) C) the children will grow up believing that life is a battle of sexesD) sharing leads to constant arguing33. The author states that bringing up children ________________.A) is mainly the mother’s jobB) belongs among the duties of the fatherC) is the job of schools and churchesD) involves a partnership of equals34. According to the author, the father’s role in the home is ____________________.A) minor because he is an ineffectual parentB) irrelevant to the healthy development of the childC) pertinent to the healthy development of the childD) identical to the role of the child’s mother35. With which of the following statements would the author be most likely to agree?A) A healthy, co-operative family is a basic ingredient of a healthy society.B) Men are basically opposed to sharing household chores.C) Division of household responsibilities is workable only in theory.D) A woman’s place in the home – now as always.Questions 36 to 40 are based on the following passage:Teaching children to read well from the start is the most important task of elementary schools. But relying on educators to approach this task correctly can be a great mistake. Many schools continue to employ instructional methods that have been proven ineffective. The staying power of the “look-say” or “whole-word” method of teaching beginning reading is perhaps the most flagrant example of this failure to instruct effectively.The whole-word approach to reading stresses the meaning of words over the meaning of letters, thinking over decoding, developing a sight vocabulary of familiar words over developing the ability to unlock the pronunciation of unfamiliar words. It fits in with the self-directed, “learning how to learn”activities recommended by advocates （倡导者）of “open”classrooms and with the concept that children have to be developmentally ready to begin reading. Before 1963, no major publisher put out anything but these “Run-Spot-Run” readers.However, in 1955, Rudolf Flesch touched off what has been called “the great debate”in beginning reading. In his best-seller Why Johnny Can’t Read, Flesch indicted（控诉）the nation’s public schools for miseducating students by using the look-say method. He said – andmore scholarly studies by Jeane Chall and Rovert Dykstra later confirmed –that another approach to beginning reading, founded on phonics（语⾳学）, is far superior.Systematic phonics first teachers children to associate letters and letter combinations with sounds; it then teaches them how to blend these sounds together to make words. Rather than building up a relatively limited vocabulary of memorized words, it imparts a code by which the pronunciations of the vast majority of the most common words in the English language can be learned. Phonics does not devalue the importance of thinking about the meaning of words and sentences; it simply recognizes that decoding is the logical and necessary first step.36. The author feels that counting on educators to teach reading correctly is _____________.A) only logical and natural B) the expected positionC) probably a mistake D) merely effective instruction37. The author indicts the look-say reading approach because _________________.A) it overlooks decoding B) Rudolf Flesch agrees with himC) he says it is boring D) many schools continue to use this method38. One major difference between the look-say method of learning reading and the phonics method is _______________.A) look-say is simpler B) Phonics takes longer to learnC) look-say is easier to teach D) phonics gives readers access to far more words39. The phrase “touch-off”(Para 3, Line 1) most probably means _____________.A) talk about shortly B) start or causeC) compare with D) oppose40. According to the author, which of the following statements is true?A) Phonics approach regards whole-word method as unimportant.B) The whole-word approach emphasizes decoding.C) In phonics approach, it is necessary and logical to employ decoding.D) Phonics is superior because it stresses the meaning of words thus the vast majority of mostcommon words can be learned.Part Three Vocabulary and StructureDirections: There are 30 incomplete sentences in this part.

2019 年 12 月大学英语四级考试模拟试卷及答案(21)PartⅡ Reading Comprehension (35 minutes)Directions ： There are 4 passages in this part.Eachpassage is followed by some questions or unfinishedstatements.For each of them there are four choices markedA),B),C) and D).You should decide on the best choice and markthe corresponding letter on the Answer Sheet with a single linethrough the center.Questions 21 to 25 are based on the following passage：Some radio singals were heard in 1967.They were comingfrom a point in the sky where there was unknown star.Theywere coming very regularly,too ：about once a second,if theywere controlled by clock.The scientists who heard the signals did not tellanybody else.They were rather afraid to tell in case theyfrightened people.The signals were coming from a very smallbody—no bigger,perhaps than the earth.Was that why no lightcould be seen from it?Or were the signals coming from aplanet that belonged to some other star?There was no end tothe questions,but the scientists kept the newssecret. “Perhaps there are intelligent beings outthere. ”they thought, “who are trying to send messages toother planets,or to us?So the news was not given to thenewspaper.Instead,the scientists studied the signals andsearched for others like them...Well,all that happened in1967 and 1968.Since then scientists have learnt more aboutthose strange,regular,radio signals.And they have toldthe story,of course.The signals do not come from a planet;they come from anew kind of star called a “pulsar ”” .About a hundred other pulsars have now been found,and most of them are very like the first one.Pulsars are strong radio stars.They are the smallest butthe heaviest stars we know at present.A handful of pulsarwould weigh a few thousand tons.Their light —if they give muchlight —is too small for us to see.But we can be sure of this,no intelligent beings are living on them.21.The radio signals discussed in this passage____.A.were regularB.were controlled by a clock答案1短文大意1967 年人收到了一些太空信号。
