大学英语四级(阅读)模拟试卷3(题后含答案及解析) 题型有: 4. Reading Comprehension (Reading in Depth)Part IV Reading Comprehension (Reading in Depth) (25 minutes)Section BDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.1.Normally a student would attend at least______classes each week.A.36B.20C.12D.15正确答案:C解析:由文章第1段可知,每个学生每学期要上4到5门课,每门课每周有3节,由此可知学生每周要上12一15节课,因此一个学生每个星期至少要上12节课.故选C。
四级考试英语阅读模拟题及答案
四级考试英语阅读模拟题及答案四级考试英语阅读模拟题(一)Newspapers often tell us of floods in some parts of the United States.Nearly every year on the great central drainages heavy rains and melting snow cause the waters to pour out the mountains and plains, to turn brooks into torrents, and to swell quiet streams into wild uncontrolled rivers. From Cairo to New Orleans, and from Pittsburgh to Paducah, the cry "River rising!" is a familiar yet fearful voice. . . When the rivers sometimes become too high or too swift to be controlled communities are flooded, families flee from their homes, croplands are washed out, and transportation comes to a halt. Hunger, disease, and death follow the wild waters.Although given less publicity, the agricultural damage done by the many smaller, more frequent floods usually far e某ceeds the losses caused by the very grand ones. In the Central States, ditches and drains cause the flows from spring rains and melting snow to run far more rapidly than in the days before white men settled on the land. Once, e某cess spring flood waters emptied into lakes and swampy lands, there to be detained for slow release into stream and rivers. Now, systematic drainage has actually eliminated these natural reservoirs.In the more rolling sections of the East, spring runoff was formerly absorbed and held temporarily in the porous soils beneath the unbroken e某panse of forest. When large areas were converted to farm use, removal of the forest and the practice of up-and-down hill plowing deprived the soils of much of their ability to catch and store water.The effects of eliminating the natural forest cover are shown in the gullied farm lands and widened stream channels found in some densely settled areas. Partly because the stream channels are more or less filled with material washed down from the uplands, and partly because storm runoff has increased, the channels are today no longer able to carry all the flow from heavy rains. This e某plains why the streams overtop banks far more often than in the days before settlement.26. The best title for the selection would be______.A. River Rising! River Rising!B. Forests and FloodsC. Flooding in the U. S.D. The Results of Flooding27. All of the following cause floods E某CEPT______.A. heavy rainB. melting snowC. increasing storm runoffD. porous soil28. The author states that______.A. lakes and swamps once acted like natural reservoirsB. up-and-down hill plowing catches and stores waterC. stream channels are the best carriers of waterD. floods are easily prevented and controlled29. According to the selection, streams overtop their bankspartly because______.A. material from higher land is washed into themB. ditches and drains lead into themC. rivers become too swiftD. snow melts more rapidly nowadays30. The floods which are given most publicity______.A. cause no damageB. cause the most damageC. cause less agricultural damage than the many smaller, more frequent floodsD. far e某ceed the smaller, more frequent floods in agricultural loss四级考试英语阅读模拟题答案26.

C四级考试英语阅读模拟题(二)When companies consider their benefits mi某.coverage for medical care is often top.of-mind.Yet there may be another,even more powerful concern driving employee coverage preferences:vision care.Roughly 75%of adults in the United States require some type of vision correction.and 84 percent of adults believe that vision benefits are somewhat or very important to them.As a result.vision assistance is moving higher and higher on the list of sought.after employee benefits.What’s driving the trend?One factor is the increasing power of eye e某aminations to detect systemic illness.In addition to identifying nearsightedness,farsightedness and astigmatism,routine eye e某anls now play a role in diagnosing conditions such as diabetes,brain aneurysms(脑动脉瘤),liver disease and stroke risk. Early identification,in turn,translates into markedly lower e某penditures for employers.In 2022,eye problems will cost companies an estimated$8 billion in reduced productivity.Making sure employees get the right eye care helps employers reduce these losses.At the same time,it boosts their ability to retain loyal workers.So what’s the best way to get patients into the e某am chair?One way is to provide a vision plan that lowers out-of-pocket(自已付费的)e某penses.Indeed,research shows that out-of-pocket e某pense--not premiums--is the number-one factor employees consider when choosing a-vision plan.“And that’s just smart.〞says independent insurance broker Shannon Enders. “Premiums make up only about 30 percent of total out.of-pocket e某penses.So it pays to100k beyond the premium and see the real cost of a plan.〞A study conducted by Service E某cellence Group Inc.,a leading market research company,shows how the right vision insurance plan can result in across—the-board(全面的)savings for employees.The study compared the prices customers with different insurance plans paid for the same popular pair of eyeglasses at independent doctors and retail chains.It found that customers with insurance plans that were most successful at keeping out-of-pocket e某penses low saved hundreds of dollars.With eyeglasses becoming as much of a fashion accessory(装饰品)as a vision aid,forward-thinking companies are beginning to takenote.Enders says more of his clients are saying yes to vision care plans.“Employees care about their eyes,〞he says.“And offering benefits packages with the features employees care most about will become an even more important corporate strategy going forward.〞61.What is the meaning of the last sentence of paragraph one?A.Vision assistance is listed on the list of popular worker interests.B.Vision assistance is becoming more and more popular among employees。

"They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table.

英语四级阅读理解模拟练习及答案详解
英语四级阅读理解模拟练习及答案详解Passage OneQuestions 57 to 61 are based on the following passage.There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among “situations vacant”, although it does not offer anyone a job, and sometimes it appears among “situations wanted”, although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job.“Contact us before writing your application”, or “Make use of our long experience in preparing your curriculum vitae or job history”, is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right.There was a time when job seekers simply wrote letters of application. “Just put down your name, address, age and whether you have passed any exams”, was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. “Your search is over. I am the person you are looking for”, was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job interview.There is no doubt, however, that it is increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.57. The new type of advertisement which is appearing in newspaper columns .A) informs job hunters of the opportunities availableB) promises to offer useful advice to those looking for employmentC) divides available jobs into various typesD) informs employers of the people available for work58. Nowadays a demand for this specialized type of service has been created because .A) there is a lack of jobs available for artistic peopleB) there are so many top?level jobs availableC) there are so many people out of workD) the job history is considered to be a work of art59. In the past it was expected that first job hunters would .A) write an initial letter giving their life historyB) pass some exams before applying for a jobC) have no qualifications other than being able to read and writeD) keep any detailed information until they obtained an interview60. Later, as one went on to apply for more important jobs, one was advised to include in the letter .A) something that would distinguish one from other applicantsB) hinted information about the personality of the applicantC) ones advantages over others in applying for the jobD) an occasional trick with the aggressive approach61. The curriculum vitae has become such an important document because .A) there has been an increase in the number of jobs advertisedB) there has been an increase in the number of applicants with degreesC) jobs are becoming much more complicated nowadaysD) the other processes of applying for jobs are more complicatedPassage TwoQuestions 62 to 66 are based on the following passage.In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent —controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low—paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.62. There is the possibility that setting maximum rent may .A) cause a shortage of apartmentsB) worry those who rent apartments as homesC) increase the profits of landlordsD) encourage landlords to invest in building apartment63. According to the critics, rent control .A) will always benefit those who rent apartmentsB) is unnecessaryC) will bring negative effects in the long runD) is necessary under all circumstances64. The problem of unemployment will arise .A) if the minimum wage is set too highB) if the minimum wage is set too lowC) if the workers are unskilledD) if the maximum wage is set65. The passage tells us .A) the relationship between supply and demandB) the possible results of government controlsC) the necessity of government controlD) the urgency of getting rid of government controls66. Which of the following statements is NOT true?A) The results of economic decisions can not always be predicted.B) Minimum wage can not always protect employees.C) Economic theory can predict the results of economic decisions if other factors are not changing.D) Economic decisions should not be based on economic theory.答案详解:57.

4级24篇阅读模拟题及答案
一.Baekeland and Hartmann report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.In general, these “short sleeps” appeared ambitious, active, energetic, cheerful, conformist(不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear “normal” or “acceptable” to their friends and associates.When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.The sleep patterns of the “short sleepers” were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic(疯人).The “long sleepers” were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the “short sleepers.”Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep wasan escape from their daily problems.1. According to the report,______.A) many short sleepers need less sleep by natureB) many short sleepers are obliged to reduce their nightly sleep time because they are busy with their workC) long sleepers sleep a longer period of time during the dayD) many long sleepers preserve their sleeping habit formed during their childhood2. Many “short sleepers” are likely to hold the view that _____.A) sleep is a withdrawal from the realityB) sleep interferes with their sound judgementC) sleep is the least expensive item on their routine programD) sleep is the best way to deal with psychological troubles3. It is stated in the third paragraph that short sleepers _____.A) are ideally vigorous even under the pressures of lifeB) often neglect the consequences of inadequate sleepC) do not know how to relax properlyD) are more unlikely to run into mental problems4. When sometimes they cannot enjoy adequate sleep, the long sleepers might ____.A) appear disturbedB) become energeticC) feel dissatisfiedD) be extremely depressed5. Which of the following is Not included in the passage?A) If one sleeps inadequately, his performance suffers and his memory is weakenedB) The sleep patterns of short sleepers are exactly the sane as those shown by many mental patientsC) Long and short sleepers differ in their attitudes towards sleepD) Short sleepers would be better off with more rest答案:DCBAB贝克尔和哈特曼报道说,“睡眠少的人”在未进入少年期之前,其正常睡眠时间大致与所需要的时间差不多。
全国英语四级阅读模拟习题附答案
全国英语四级阅读模拟习题附答案全国英语四级阅读模拟习题附答案在当今这个学习英语风潮盛行的社会,英语似乎已经成为了我们生活中不可或缺的一局部,下面是为大家搜索的英语四级辅导练习,希望能给大家带来帮助!I’m usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today’s children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.Why are America’s kids so stressed? The report cites two main causes: increasing physical isolation—brought on by high divorce rates and less involvement in munity, among other things—and a growing perception that the world is a more dangerous place.Given that we can’t turn the clock back, adults can still do plenty to help the next generation cope.At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is anisland. Strengthening social ties helps build munities and protect individuals against stress.To help kids build stronger connections with others, you can pull the plug on TVs and puters. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.Limit the amount of virtual (虚拟的) violence your children are exposed to. It’s not just video games andmovies; children see a lot of murder and crime on the local news.Keep your expectations for your children reasonable. Many highly suessful people never attended Harvard or Yale.Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a goodmodelfor your kids. Sometimes anxiety is unavoidable. But it doesn’t have to ruin your life.1.The author thinks that the conclusions of any research about people’s state of mind are .A. surprisingB. confusingC. illogicalD. questionable2. What does the author mean when he says, “we can’t turn the clock back” (Line 1, Para. 3)?A. It’s impossible to slow down the pace of change.B. The social reality children are facing cannot be changed.C. Lessons learned from the past should not be forgotten.D. It’s impossible to forget the past.3.Aording to an analysis, pared with normal children today, children treated as mentallyill 50 years ago .A. were less isolated physicallyB. were probably less self-centeredC. probably suffered less from anxietyD. were considered less individualistic4.The first and most important thing parents should do to help their children isA. to provide them with a safer environmentB. to lower their expectations for themC. to get them more involved sociallyD. to set a good model for them to follow5.What conclusion can be drawn from the passage?A. Anxiety, though unavoidable, can be coped with.B. Children’s anxiety has been enormously exaggerated.C. Children’s anxiety can be eliminated with more parental care.D. Anxiety, if properly controlled, may help children bee mature.1.[D] 题目中的`people’s state of mind就是本文第1句中either happier or unhappier or more or less certain of themselves。
(完整word版)英语四级阅读理解模拟试题及答案
英语四级阅读理解模拟试题及答案Our quarrel with efficiency is not that it gets things done,but that it is a thief of time when it leaves us no leisure to enjoy ourselves, and that it strains our nerves when we try toget things done perfectly. In building bridges, American engineers calculate so finely and exactly as to make the twoends come together within one-tenth of an inch. But when twoChinese begin to dig a tunnel from both sides of a mountainboth come out on the other side. --The Chinese’s firm belief is that it doesn ’t matter so long as a tunnel is dug through, and ifwe have two instead of one, why, we have a double track toboot.The pace of modern industrial life forbids this kind of glorious and magnificent idling. But, worse than that, it imposes upon us a different conception of time as measuredby the clock and eventually turns the human being into a clock himself. (This sort of thing is bound to come to China, as is evident, for instance, in the case of a factory of twenty thousand worker. The luxurious prospect of twenty thousandworkers coming in at their own sweet pleasure at all hours is,of course, somewhat terrifying.)Nevertheless, such efficiency iswhat makes life so hard and full of excitement. A man who hasto be punctually at a certain place at five o ’clock has the whole afternoon from one to five ruined for him already. Every American adult is arranging his time on the pattern of the schoolboy - three o ’clock for this, five o ’ clock for that, six-thirty for change of dress, six-fifty for entering the taxi, andseven o ’clock for arriving at the destination. It just makes lifenot worth living.1.The writer objects to efficiency mainly on thegrounds that it ____.A) entitles us to too much leisure time B)urges us to get things done punctually C)deprives us of leisure timeD) imposes on us a perfect concept of time2.In the eyes of the author, the introduction ofindustrial life gives rise to ____.A) the excitement of lifeB) magnificent idling of timeC) more emphasis on efficiencyD) terrifying schoolboy3.The passage tells us ____.A)Chinese workers come to work when it is convenientB)all Americans are forced to be efficient against their willC)Chinese engineers are on better terms with the managementD)Americans ought not to work so hard for efficiency4.The author believes that relaxing the rule ofpunctuality in factories would lead to ____.A) great confusionB) increased production C)a hard and exciting lifeD) successful completion of a tunnel5.What is implied but NOT stated by the author is that____.A) every American is arranging his time in the pattern of a schoolboyB) every American is reluctant to be efficientC)every one should have some time to spend as he pleasesD) being punctual is an undesirable habit which should not be formed答案:1.C)deprives us of leisure time 对应原文第一句 but that it is a thief of time when it leaves us no leisure to enjoy ourselves.选项 A 是与作者想法完整相反的; 选项 B 虽有章可循 , 但要注意原文是it strains our nerves when we try to get things done perfectly, 而非it 直接 urges us to get things done punctually;选项 D 要看清 , 原文是 a different conception of time而非 a perfect concept of time.The2.C)more emphasis on efficiency 对应原文第二段第一句pace of modern industrial life forbids this kind of glorious and magnificent i dling.经过第一段能够看出,与efficiency对峙的是this kind of glorious and magnificent idling, 而 industrial life 又forbids, 自然说明 industrial life gives rise to more emphasis on efficiency.3.D)Americans ought not to work so hard for efficiency. 排除法 : A)Chinese workers come to work when it is convenient 不切合原文()中的内容 ; B)all Americans are forced to be efficient against their will 语气太重, 不是被逼迫讲究效率 , 也不是违反自己意向 , 不过为了适应工业社会; C)Chinese engineers are on better terms with the management不属于本文议论范围。

大学英语四级阅读模拟题及答案(3篇)
大学英语四级阅读模拟题及答案阅读1空调的危害Although many of us may feel air-conditioners bring relief from hot,humid or polluted outside air,they pose many potential health hazards.Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.One of the more widely publicized dangers is that of Legionnaire’s disease,which was first recognized inthe1970s.This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’cooling towers was somehow sucked back into the air intake(通风口),in mostcases due to poor design.The warm air,filled with bacteria,was combined with cooled,conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.Large air-conditioning systems add water to the air they circulate by means of humidifiers(湿度调节器).Inolder systems,the water used for this process is kept in special reservoirs,the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通风)system.The risk to human health from this situation has been highlighted by the fact that the immune systems(免疫系统)of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called“biocides”are added to reservoirs to make them germ-free,and they are dangerous in their own right in sufficient quantities,as they often contain compounds strongly linked to cancers.Finally,it should be pointed out that the artificial climatic environment created byair-conditioners canalso affect us.In a natural environment,whether indoor or outdoor,there are small variations in temperature and humidity.Indeed,the human body has long been accustomed to these normal changes.In an air-conditioned living or working environment,however,body temperatures remain well under37℃,our normal temperature.This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.练习题:Choose correct answers to the question:1.What do we know about Legionnaire's disease from the passage?A.It was the most widely concerned office hazard.B.It can affect people both inside and outside the building.C.It happens only in air-conditioned office buildings.D.It does not develop in well-designed buildings.2.In the old air-conditioned systems,bacteria first develop______.A.in the reservoirsB.in the ventilation systemc.in the humidifiersD.in the air intake3.The fact that about half of workers developed the ability to fight off the bacteria may__.A.relieve people’s worry about the danger caused by the bacteriaB.help people find an effective way to get rid of the bacteriaC.reflect the serious danger brought by the bacteriaD.cause serious disease such as cancers to people4.The author most probably wants the readers to treat biocides with an attitude of_.A.cautionB.trustC.enthusiasmD.criticism5.The last paragraph implies that our immune system can be weakened when_•A.we live in an artificial climatic environmentB.there are variations in temperature and humidityC.our body temperatures often remain not high enoughD.we are often exposed to diseases such as colds and flu答案解析:1.[B]事实细节题。

英语四级考试阅读模拟题(一)Where do pesticides fit into the picture of environmental disease? We have seen that they now pollute soil,water and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world: We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farmworkers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time, and that the danger to individual may depend on the sum of the exposures received throughout his lifetime. For these veryreasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster.

四级考试英语阅读模拟题(一)Asked to name their favorite city, many Amerians would select San Francisco which began as a small Spanish outpost located on a magnificent bay.The town was little more than a village serving ranchers when the United States took possession of it in 1846 during the war with Mexico.San Francisco sprang into a city overnight because of the nearby discovery of gold in 1848. A great rush to California took place. Wagon trains plodded their dangerous way across 2000 miles of prairie and mountains, while hundreds of sailing vessels made the equally hazardous trip around the Horn. The vessels disgorged thousands of passengers -- then the crews deserted their ship and hundreds of vessels were left to rot in the bay. Within two years, California had enough population to become a state and San Francisco was for many years the hub of that newly-arrived population.The city's present popularity is due to an excellent climate, an easy style of living , good food, and numerous tourist attractions. The city is famous for its cable cars which "clang and bang" up the steep hills, and for its excellent seafood stals along the wharf. Most visitors arriving from nations in the Pacific Basin spend several days getting to know the town.1.According to this article, who were the first Californians?A. deserters from sailing ships b. Spanish ranchersc. gold minersd. tourists2. San Francisco's appeal includes all of the following factors____.a.attractive lifestyle, good seafood, desirable weatherb.tourist attactions, extreme seasons, cable carsc.wagon trains, gold mining, good climated.cable cars, pleasant climate, flat terrain3.San Francisco today is a thriving city because of ____.A. heavy industry b. governmental headquartersc. Gold miningd. trade and tourism4. In which year did California become an American state?a.1850b.1852c.1846d.1848四级考试英语阅读模拟题答案bada四级考试英语阅读模拟题(二)Personality is , to large extent, inherent --A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is improtant to the parents, it is likely to become a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. T oo many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences:remember that Pheidippides ,the first marathon runner, dropped dead seconds after saying:"Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations . It is a rare school that allows pupils to concentrate on those things they do well.The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into 'B's. The would needs types, and schools have an important duty to try to fit a child's personality to his possible future employment. It is top management.1. According to the author, what factors contribute to the building of personality?A. inheritanceb. inheritance, competition and environmentc. competitiond. environment2.Which of the following statements is not true according to the author of the passage?A. Schools usually adopt severe competitive policies.B. Students are often divided by competition results.C. School is place where children cultivate their characteristics.D.

Schools abolish all forms of examinations.四级考试英语阅读模拟题答案bdccb。
英语四级阅读理解模拟试题附答案
英语四级阅读理解模拟试题附答案英语四级阅读理解模拟试题:【原文】There are two factors which determine an individuals intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individuals intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(抚养) homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Marks I. Q. was 125, twenty-five points higherthan the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.英语四级阅读理解模拟试题:【题目】21. This selection can best be titled____________.A.

According to the passage, the average I. Q. is_______.A. 85 .B. 100C. 110D. 12524. The case history of the twins appears to support the conclusion that_______.A. individuals with identical brains seldom test at the same levelB. an individuals intelligence is determined only by his environmentC. lack of opportunity blocks the growth of intelligenceD. changes of environment produce changes in the structure of the brain25.

英语四级阅读模拟题及答案(2021年-2022年)
英语四级阅读模拟题及答案大学英语四级阅读模拟题及答案,祝同学们考试顺利!The world has become a world of cities. With the present rate of urban growth(3. 8% in the Third World) , the majority of the population of the world will be living in cities by the year 2000. This will transform the rural-urban equation which has marked the history of mankind up to now and will call for new example and a great deal of innovation to face this phenomenon.This being so, one must accept the fact that for some years to come, no policy will be capable of stopping or reversing the present migratory trend from the rural areas to the cities in the Third World. In Africa, the urban population will reach 330 million people by the end of the century as against 150 million in 1995.The number of people living in shanty-towns (贫富窟) will inevitably increase in spite of the efforts to improve housing conditions. Africa alone needs to build 12 million housing units between now and the year 2000 to meet its most basic needs. In an ILO study, M. S. V. Sethuraman estimates that in 70 Third "World cities the proportion of people living in shanty-towns varies from 15% to 70% and that about US $ 116 billion is required to giveminimum comfort to these people by the turn of the century—less than US $ 10 billion per year.The world population is growing at a rate of about 90 million people per year, with the Third World accounting for 80 million of them. The pressure on cities can only go on increasing. The urban population of the developing countries will exceed 2 billion people by the year 2000 and since the main reason for the high demographic (人口统计的) growth is poverty, the additional population will be mostly made of people of very limited means.21. If the urban population of the developing countries exceeds 2 billion people by the year 2000, the main problem the additional people will face is______.A. housingB. foodC. povertyD. limited land22. According to the passage, "about US $116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year. " Do you think which year was the article written by saying "less than $ 10 billion per year" by the turn of the century?A. 1985.B. 1990.C. 1988.D. 2000.23. The mankind should face the phenomenon that the world has become a world of cities with______.A. a lot of difficultiesB. efforts to improve housing conditionC. pressure of the basic needsD. new models and a great deal of transformation of ideas and methods24. In Africa, people in cities will be______by the end of the century.A. almost twice as much as in 1985B. doubled than that in 1985C. over twice as much as in 1985D. 300 million25. In spite of the efforts to improve housing condition, the number of people living in shanty-towns will increasebecause______.A. houses in shanty-towns are cheapB. shanty-towns could provide people with minimum comfortC. no policy will be capable of stopping or changing the present immigrant tendency from the rural areas to the cities in the Third WorldD. the Third Word population is growing at a rate of about 80 million people per year答案:21.

英语四级仔细阅读模拟试题附答案
英语四级仔细阅读模拟试题附答案英语四级仔细阅读模拟试题1:Fried foods have long been frowned upon. Nevertheless, the skillet (长柄平底煎锅) is about our handiest and most useful piece of kitchen equipment. Strong woodcutters and others engaged in active labor requiring 4,000calories per day or more will take approximately one-third of their rations prepared in this fashion. Meat, eggs, and French toast cooked in this way are served in millions of homes daily. Apparently the consumers are not beset with more signs of indigestion than afflicted by those who insist upon broiling, roasting, or boiling. Some years ago one of our most eminent physiologists investigated the digestibility of fried potatoes. He found that the pan variety was more easily broken down for assimilation than when deep fat was employed. The latter, however, dissolved within the alimentary tract ( 消化道 ) more readily than the boiled type. Furthermore, he learned, by watching the progress of the contents of the stomach by means of the fluoroscope (荧光检查仪), that fat actually accelerated the rate of digestion. Now all this is quite in contrast with "authority". Volumes have been written on nutrition, and everywhere the dictum ( 权威意见) has been accepted--no fried edibles of any sort for children. A few will go so tar as to forbid this style of cooking wholly. Now and then an expert will be bold enough to admit that he uses them himself, the absence of discomfort being explained on the ground that he possesses a powerful gastric ( 胃的 )apparatus. We can ofcourse sizzle perfectly good articles to death so that they will be leathery and tough. But thorough heating, in the presence of shortening, is not the awful crime that it has been labeled. Such dishes stimulate rather than retard contractions of the gall bladder. Thus it is that bile ( 胆汁 ) mixes with the nutriment shortly after it leaves the stomach.We dont need to allow our foodstuffs to become oil soaked, but other than that, there seems to be no basis for the widely heralded prohibition against this method. But notions become fixed. The first condemnation probably rose because an "oracle" ( 圣贤) suffered from dyspepsia (消化不良) which he ascribed to some fried item on the menu. The theory spread. Others agreed with him, and after a time the doctrine became incorporated in our textbooks. The belief is now tradition rather than proved fact. It should have been refuted long since, as experience has demonstrated its falsity.56. This passage focuses on__________.A. why the skillet is a handy piece of kitchen equipmentB. the digestibility of fried foodsC. how the experts can mislead the public in the area of food preparationD. why fried foods have long been frowned upon57. People engaged in active labor eat fried foods because __________.A. they are healthfulB. they are much cheaperC. they can be easily digestedD. they can provide the calories the workers need58. The author implies that the public should__________.A. prepare some foods by fryingB. avoid fried foods if possibleC. fry foods for adults but not for childrenD. prepare all foods by frying59. When the author says that "an oracle suffered from dyspepsia which he ascribed to some fried item on the menu" he is being__________.A. gratefulB. factualC. sarcasticD. humorous60. The passage was probably taken from__________.A. a medical journalB. a publication addressed to the general publicC. a speech at a medical conventionD. an advertisement for cooking oil英语四级仔细阅读模拟试题答案:56.B定位:根据题干信息this passage focuses on可知解答本题需通观全文。

今天,店铺准备了大学英语四级阅读理解模拟题,以供考生练习。
大学英语四级阅读理解模拟题:【原文】According to a survey, which was based on the responses of over 188,000 students, today’s traditional-agecollege freshmen are ”more materialistic and less altruistic (利他主义的)” than at any time in the 17 years of the poll.Not surprising in these hard times, the student’s major objective “is to be financially well off. Less important than ever is developing a meaningful philosophy of life.” It follows then that today the most popular course is not literature or history but accounting.Interest in teaching, social service and the“altruistic”fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up.That’s no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job-even before she completed her two-yearassociate degree.While it’s true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions m be they scientific or artistic. It is equally true that, in studying thediverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs.Weekly we read of unions who went on strike for higherwages, only to drive their employer out of business.No company; no job. How shortsighted in the long run!But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机): “Miss Baxter,”he says, “could you pl ease send in someone who can distinguish right from wrong?”From the long-term point of view, that’s what education really ought to be about.大学英语四级阅读理解模拟题:【题目】Choose correct answers to the question:1. According to the author’s observation, college stude nts _______.A. have never been so materialistic as todayB. have never been so interested in the artsC. have never been so financially well off as todayD. have never attached so much importance to moral sense2. The students’ criteria for selecting majors today have much to do with _______.A. the influences of their instructorsB. the financial goals they seek in lifeC. their own interpretations of the coursesD. their understanding of the contributions of others3. By saying “While it’s true that ... be they scientific or artistic” (Lines 1-3, Para. 5), the author means that _______.A. business management should be included in educational programsB. human wisdom has accumulated at an extraordinarily highspeedC. human intellectual development has reached new heightsD. the importance of a broad education should not be overlooked4. Studying the diverse wisdom of others can ________.A. create varying artistic interestsB. help people see things in their right perspectiveC. help improve connections among peopleD. regulate the behavior of modern people5. Which of the following statements is true according to the passage?A. Businessmen absorbed in their career are narrow-minded.B. Managers often find it hard to tell right from wrong.C. People engaged in technical jobs lead a more rewarding life.D. Career seekers should not focus on immediate interests only.大学英语四级阅读理解模拟题:【答案】1.[A]事实细节题。
英语四级阅读理解模拟练习及参考答案
英语四级阅读理解模拟练习及参考答案are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A,B,C and D .You shoulddecide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneNow let us look at how we read. When we read a printed text, our eyes move across a page in short, jerky movement. We recognize words usually when our eyes are still when they fixate. Eachtime they fixate, we see a group of words. This is known as the recognition span or the visual span. The length of time ofr which the eyes stop ---the duration of the fixation ----variesconsiderably from person to person. It also vaies within any one person according to his purpose in reading and his familiarity with the text. Furthermore, it can be affected by such factors aslighting and tiredness.Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page. As aresult of this misleading emphasis on the purelyvisual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation. For instance, in some exercises, words are flashed on to a screen for, say,a tenth or a twentieth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words oneither side. Such word patterns are oftenconstructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive fixation. All these exercises are very clever, but it’s one thing to improve aperson’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently,for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated words and phrases would seemunlikely to help him in reading a continuous text.Q:1. The time of the recognition span can be affected by the following facts except ________ .A. one’s familiarity with the textB. one’s purpose in readingC. the length of a group of wordsD. lighting and tiredness2. The author may believe that reading ______.A. requires a reader to take in more words at each fixationB. requires a reader to see words more quicklyC. demands an deeply-participating mindD. demands more mind than eyes3 What does the author mean by saying “but it’s one thing to improve a person’s ab ility to see words and quite another thing to improve his ability to read a text efficiently.” in the secondparapraph?A. The ability to see words is not needed when an efficient reading is conducted.B. The reading exercises mentioned can’t help to improve both the ability to see and to comprehend words.C. The reading exercises mentioned can’t help to improve an efficient reading.D. The reading exercises mentioned has done a great job to improve one’s ability to see words.4. Which of the following is NOT true?A. The visual span is a word or a group of words we see each time.B. Many experts began to question the efficiency of eye training.C. The emphasis on the purely visual aspects is misleading.D.The eye training will help readers in reading a continuous text.5. The tune of the author in writing this article is ________A criticalB neutralC prssimisticD optimistic答案:CCCDA1 C。
大学英语四级阅读理解模拟试题及答案
大学英语四级阅读理解模拟试题及答案大学英语四级阅读理解模拟试题及答案「篇一」1. C 细节题。
因为Leadville可以为Tabor带来巨富。
这一点不是Leadville得名的原因,因为在文章第二段中,讲到这一点时,提及三个原因:A.因为Tabor成为当地的居民代表人物,B.因为在Leadville有丰富的铅的储藏量。
D.因为Leadville是因为Tabor重要而起的名。
2. D 词汇题。
第二段中grubstake的词义与D所述内容是相同的,即“供给探矿者资金,衣物,食品以及其他物品”。
3. A 细节题。
Tabor第一次真正发财是他为两名矿工提供资助,为此他获得他们矿资源三分之一的股份。
见文章第三段4-9行内容:两名开矿者从Tabor那儿借走价值17美元的物品,作为回报,Tabor获得他们矿资源三分之一股份。
于是两位开矿者在一座山旁的不毛之地开始挖掘,九天之后,发现了银的富矿,于是Tabor又将两人的.股份全买下,这样,银矿属于Tabor一个人所有,这个矿就是后来著名的“匹兹堡”矿。
Tabor用17美元的投资换来了130万美元的收获。
4. B 推断题。
由原文可知泰勃的财产来源是有一定偶然性的,但是毕竟也是基于他开创“grubstake”模式,因为A、D都不对,C更是没有根据,因为他还没有娶第二位夫人这一切就发生了。
分析泰勃的做法,会得出B选项所示的结论。
5. B 推断题。
如果本文是一篇文章的第一部分,那么在文章的第二部分将介绍谁呢?可以从文章第一句分析出来,在Leadville的黄金年代,其多彩的特点当中,Tabor及其第二任妻子Elizabeth McCourt是值得大书特书的,接着,文章都在讲述有关H.A.W.Tabor发家致富的历史,如先买下匹兹堡矿,后又买下Matchless矿,最后成为市长,代理州长,等等,所以涉及到的全是男主人公,因此下边再讲的话,应成为女主人公即Elizabeth McCourt的天地了,她是Tabor的第二任妻子。

The human brain contains 10 thousand million cells and each of these may have a thousandconnections. Suchenormous numbers used to discourage us and cause us to dismiss thepossibility of making a machine with human -like ability, but now that we have grown used tomoving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps,we will be able to assemble a machine as complex as the human brain, and if we can we will. Itmay then take us a long time to render it intelligent by loading in the right software (软件)orby altering the architecture but that too will happen.I think it certain that in decades, not centuries, machines of silicon (硅)will arise first to rivaland then exceed their human ancestors. Once they exceed us they will be capable of theirown design. In a real sense they will be able to reproduce themselves. Silicon will have endedcarbons long control. And we will no longer be able to claim ourselves to be the finestintelligence in the knownuniverse.As the intelligence of robots increases to match that of humans and as their cost declinesthrough economies of scale we may use them to expand our frontiers, first on earth throughtheir ability to withstand environments, harmful to ourselves. Thus, deserts may bloom andthe ocean beds be mined. Further ahead, by a combination of the great wealth this new agewill bring and the technology it will provide, the construction of a vast, man-created world inspace, home to thousands or millions of people, will be within our power.练习题:Choose correct answers to the question:1.1.In what way can we make a machine intelligent?A. By making it work in such environments as deserts, oceans or space.B. By working hard for 10 or 20 years.C. By either properly programming it or changing its structure.D.

第1段末提到,使机器具有智能的方法有两种,要么安装合适软件,要么改变其架构,故C正确。
2.[A] 观点态度题。
作者在最后一段提到智能机器人可为人类做很多好事,故他对机器人态度是肯定的,故A正确,同时排除C。
文中只是说机器人会超越人类,但并未提到会控制人类,故B排除;D与第1段末的that toowill happen矛盾,故错误。
3.[D] 词义理解题。
文中提到"硅"将会终结"碳"的长期统治地位,联系上文可知,"硅"指的是智能机器人,再结合上文的机器人会超越人类,故可确定"碳"指代的是人类。
