2020年12月英语四级试题一仔细阅读真题答案(网友版)Everybody sleeps—so goes theSesame Street song meant for obstinately awakechildren. That may be true, but what people stay up late tocatch—or wake up early in order not to miss—varies byculture.Around the world, people changed sleep patterns thanks to the startor end of daylight savings time. Russians, for example, began towake up about a half-hour later each day after President VladimirPutin shifted the country permanently to “winter time”star ting on October 26.Russia’s other latenights and early mornings generally coincided with public holidays.One such spike was on New Year’s Eve, which Russians tend to ringin with unusual fervor, as well as on World War II Victory Day.According to another Jawbonefinding,Russians have the world's latest bedtime on December 31, hittingthe hay at around 3:30 a.m.Russians also got upan hour later on International Women’s Day, the day for coddlingand celebrating female relatives.Similarly, Americans’late nights, late mornings, and longest sleeps coincided withthree-day weekends.Canada got the leastsleep of the year the night it beat Sweden in the Olympic hockeyfinal.The World Cup wasalso a major sleep-deprivation culprit. The worst night for sleepin the U.K. was the night of theEngland-Italy match on June 14.Brits stayed up a half-hour later to watch it, and then they wokeup earlier than usualthe next morning thanks to summer nights, thephenomenon in which the sun barely sets in northern countries inthe summertime. That was nothing, though, compared toGermans,Italians, and the French, who stayed up around anhour and a halflater on various days throughout the summer to watch theCup.It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it’s likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that’s the case, though, the above findings are still striking. If the most healthconscious among us have such deep swings in our shuteye levels throughout the year, how much sleep are the rest of us losing?参考答案及解析61题,定位到第一段最后一句“varies byculture”,所以答案选A——They areculture-related.62题,由题干的大写名词Russian定位到第二段和第三段。

大学英语四级仔细阅读专项练习20篇(附答案)

大学英语四级仔细阅读专项练习20篇(附答案)练习一(2010年12月大学英语四级考试真题)Passage OneQuestions 57 to 61 are based on the following passage.It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial considerations.Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee's is one of them.The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制药的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities.Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates willcontinue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”57. By “a one-way street” (Line 1, Para. 1), the author means ________.[A] university researchers know little about the commercial world[B] there is little exchange between industry and academia[C] few industrial scientists would quit to work in a university[D] few university professors are willing to do industrial research58. The word “deterrent” (Line 2, Para. 1) most probably refers to something that ________.[A] keeps someone from taking action [C] attracts people's attention[B] helps to move the traffic [D] brings someone a financial burden59. What was Helen Lee's major consideration when she changed her job in the middle of her career?[A] Flexible work hours. [C] Her preference for the lifestyle on campus.[B] Her research interests. [D] Prospects of academic accomplishments.60. Guy Grant chose to work as a researcher at Cambridge in order to ________.[A] do financially more rewarding work[B] raise his status in the academic world[C] enrich his experience in medical research[D] exploit better intellectual opportunities61. What contribution can industrial scientists make when they come to teach in a university?[A] Increase its graduates' competitiveness in the job market.[B] Develop its students' potential in research.[C] Help it to obtain financial support from industry.[D] Gear its research towards practical applications.Passage TwoQuestions 62 to 66 are based on the following passage.Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all do the trick, but the biggest longevity (长寿) boost seems to come from marriage or an equivalent relationship. The effect was first noted in 1858 by William Farr, who wrote that widows and widowers (鳏夫) were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's. The effect holds for all causes of death, whether illness, accident or self-harm.Even if the odds are stacked against you, marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a flip side, however, as partners are more likely to become ill or die in the couple of years following their spouse's death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.So how does it work? The effects are complex, affected by socio-economic factors, health-service provision, emotional support and other more physiological (生理的) mechanisms. For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.A life partner, children and good friends are all recommended if you aim to live to 100. The ultimate social network is still being mapped out, but Christakis says: “People are interconnected, so their health is interconnected.”62. William Farr's study and other studies show that _________.[A] social life provides an effective cure for illness[B] being sociable helps improve one's quality of life[C] women benefit more than men from marriage[D] marriage contributes a great deal to longevity63. Linda Waite's studies support the idea that _________.[A] older men should quit smoking to stay healthy[B] marriage can help make up for ill health[C] the married are happier than the unmarried[D] unmarried people are likely to suffer in later life64. It can be inferred from the context that the “flip side” (Line 4, Para. 2) refers to _________.[A] the disadvantages of being married[B] the emotional problems arising from marriage[C] the responsibility of taking care of one's family[D] the consequence of a broken marriage65. What does the author say about social networks?[A] They have effects similar to those of a marriage.[B] They help develop people's community spirit.[C] They provide timely support for those in need.[D] They help relieve people of their life's burdens.66. What can be inferred from the last paragraph?[A] It's important that we develop a social network when young.[B] To stay healthy, one should have a proper social network.[C] Getting a divorce means risking a reduced life span.[D] We should share our social networks with each other.练习二(2010年6月英语四级考试真题)Passage OneQuestions 57 to 61 are based on the following passage.You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India Ocean, June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.57. What does the author say about the black box?A) It ensures the normal functioning of an airplane.B) The idea for its design comes from a comic book.C) Its ability to ward off disasters is incredible.D) It is an indispensable device on an airplane.58. What information could be found from the black box on the Yemeni airliner?A) Data for analyzing the cause of the crash.B) The total number of passengers on board.C) The scene of the crash and extent of the damage.D) Homing signals sent by the pilot before the crash.59. Why was the black box redesigned in 1965?A) New materials became available by that time.B) Too much space was needed for its installation.C) The early models often got damaged in the crash.D) The early models didn't provide the needed data.60. Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?A) To distinguish them from the colour of the plane.B) To caution people to handle them with care.C) To make them easily identifiable.D) To conform to international standards.61. What do we know about the black boxes from Air France Flight 447?A) There is still a good chance of their being recovered.B) There is an urgent need for them to be reconstructed.C) They have stopped sending homing signals.D) They were destroyed somewhere near Brazil.Passage TwoQuestions 62 to 66 are based on the following passage.The $11 billion self-help industry is built on the idea that you should turn negative thoughts like “I never do anything right” into positive ones like “I can succeed.” Butwas positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better. If you tell your dim friend that he has the potential of an Einstein, you're just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays opposing funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written.In this experiment, Wood, Lee and Perunovic measured 68 students' self-esteem. The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, “I am lovable.”Those with low self-esteem didn't feel better after the forced self-affirmation. In fact, their moods turned significantly darker than those of members of the control group, who weren't urged to think positive thoughts.The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation (静思) techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic perspective. Call it the power of negative thinking.62. What do we learn from the first paragraph about the self-help industry?A) It is a highly profitable industry.B) It is based on the concept of positive thinking.C) It was established by Norman Vincent Peale.D) It has yielded positive results.63. What is the finding of the Canadian researchers?A) Encouraging positive thinking many do more harm than good.B) There can be no simple therapy for psychological problems.C) Unhappy people cannot think positively.D) The power of positive thinking is limited.64. What does the author mean by “… you're just underlining his faults” (Line 4, Para.3)?A) You are not taking his mistakes seriously enough.B) You are pointing out the errors he has committed.C) You are emphasizing the fact that he is not intelligent.D) You are trying to make him feel better about his faults.65. What do we learn from the experiment of Wood, Lee and Perunovic?A) It is important for people to continually boost their self-esteem.B) Self-affirmation can bring a positive change to one's mood.C) Forcing a person to think positive thoughts may lower their self-esteem.D) People with low self-esteem seldom write down their true feelings.66. What do we learn from the last paragraph?A) The effects of positive thinking vary from person to person.B) Meditation may prove to be a good form of psychotherapy.C) Different people tend to have different ways of thinking.D) People can avoid making mistakes through meditation.练习三(2013年6月大学英语四级考试真题)Passage OneQuestions 57 to 61 are based on the following passage.Junk food is everywhere. We're eating too much of it. Most of us know what we're doing and yet we do it anyway.So here's a suggestion offered by two researchers at the Rand Corporation: Why not take a lesson from alcohol control policies and apply them to where food is soldand how it's displayed?“Many policy measures to control obesity(肥胖症)assume that people consciously and rationally choose what and how much they eat and therefore focus on providing information and more access to healthier foods,” note the two researchers.“In contrast,” the researchers continue, “many regulations that don't assume people make rational choices have been successfully applied to control alcohol, a substance — like food — of which immoderate consumption leads to serious health problems.”The research references studies of people's behavior with food and alcohol and results of alcohol restrictions, and then lists five regulations that the researchers think might be promising if applied to junk foods. Among them:Density restrictions: licenses to sell alcohol aren't handed out unplanned to all comers but are allotted(分配)based on the number of places in an area that already sell alcohol. These make alcohol less easy to get and reduce the number of psychological cues to drink.Similarly, the researchers say, being presented with junk food stimulates our desire to eat it. So why not limit the density of food outlets, particularly ones that sell food rich in empty calories? And why not limit sale of food in places that aren't primarily food stores?Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can't buy alcohol at drive-through facilities. At supermarkets, food companies pay to have their wares in places where they're easily seen. One could remove junk food to the back of the store and ban them from the shelves at checkout lines. The other measures include restricting portion sizes, taxing and prohibiting special price deals for junk foods, and placing warning labels on the products.57. What does the author say about junk food?A) People should be educated not to eat too much.B) It is widely consumed despite its ill reputation.C) Its temptation is too strong for people to resist.D) It causes more harm than is generally realized.58. What do the Rand researchers think of many of the policy measures to control obesity?A) They should be implemented effectively.B) They provide misleading information.C) They are based on wrong assumptions.D) They help people make rational choices.59. Why do policymakers of alcohol control place density restrictions?A) Few people are able to resist alcohol's temptations.B) There are already too many stores selling alcohol.C) Drinking strong alcohol can cause social problems.D) Easy access leads to customers' over-consumption.60. What is the purpose of California's rule about alcohol display in gas stations?A) To effectively limit the density of alcohol outlets.B) To help drivers to give up the habit of drinking.C) To prevent possible traffic jams in nearby areas.D) To get alcohol out of drivers' immediate sight.61. What is the general guideline the Rand researchers suggest about junk food control?A) Guiding people to make rational choices about food.B) Enhancing people's awareness of their own health.C) Borrowing ideas from alcohol control measures.D) Resorting to economic, legal and psychological means.Passage TwoQuestions 62 to 66 are based on the following passage.Kodak's decision to file for bankruptcy(破产)protection is a sad, though not unexpected, turning point for a leading American corporation that pioneered consumer photography and dominated the film market for decades, but ultimatelyfailed to adapt to the digital revolution.Although many attribute Kodak's downfall to “complacency(自满)”, that explanation doesn't acknowledge the lengths to which the company went to reinvent itself. Decades ago, Kodak anticipated that digital photography would overtake film — and in fact, Kodak invented the first digital camera in 1975 — but in a fateful decision, the company chose to shelf its new discovery to focus on its traditional film business.It wasn't that Kodak was blind to the future, said Rebecca Henderson, a professor at Harvard Business School, but rather that it failed to execute on a strategy to confront it. By the time the company realized its mistake, it was too late.Kodak is an example of a firm that was very much aware that they had to adapt, and spent a lot of money trying to do so, but ultimately failed. Large companies have a difficult time switching into new markets because there is a temptation to put existing assets into the new businesses.Although Kodak anticipated the inevitable rise of digital photography, its corporate(企业的)culture was too rooted in the successes of the past for it to make the clean break necessary to fully embrace the future. They were a company stuck in time. Their history was so important to them. Now their history has become a liability.Kodak's downfall over the last several decades was dramatic. In 1976, the company commanded 90% of the market for photographic film and 85% of the market for cameras. But the 1980s brought new competition from Japanese film company Fuji Photo, which undermined Kodak by offering lower prices for film and photo supplies. Kodak's decision not to pursue the role of official film for the 1984 Los Angeles Olympics was a major miscalculation. The bid went instead to Fuji, which exploited its sponsorship to win a permanent foothold in the marketplace.62. What do we learn about Kodak?A) It went bankrupt all of a sudden.B) It is approaching its downfall.C) It initiated the digital revolution in the film industry.D) It is playing a dominant role in the film market.63. Why does the author mention Kodak's invention of the first digital camera?A) To show its early attempt to reinvent itself.B) To show its effort to overcome complacency.C) To show its quick adaptation to the digital revolution.D) To show its will to compete with Japan's Fuji photo.64. Why do large companies have difficulty switching to new markets?A) They find it costly to give up their existing assets.B) They tend to be slow in confronting new challenges.C) They are unwilling to invest in new technology.D) They are deeply stuck in their glorious past.65. What does the author say Kodak's history has become?A) A burden.B) A mirror.C) A joke.D) A challenge.66. What was Kodak's fatal mistake?A) Its blind faith in traditional photography.B) Its failure to see Fuji photo's emergence.C) Its refusal to sponsor the 1984 Olympics.D) Its overconfidence in its corporate culture.练习四(2014年6月英语四级考试真题)Passage OneQuestions 56 to 60are based on the following passage.The question of whether our government should promote science and technology or the liberal arts in higher education isn't an either/or proposition(命题),although the current emphasis on preparing young Americans for STEM (science, technology, engineering, maths)----related fields can make it seem that way.The latest congressional report acknowledges the critical importance of technicaltraining, but also asserts that the study of the humanities (人文学科)and social sciences must remain central components of America's educational system at all levels. Both are critical to producing citizens who can participate effectively in our democratic society, become innovative (创新的) leaders, and benefit from the spiritual enrichment that the reflection on the great ideas of mankind over time provides.Parents and students who have invested heavily in higher education worry about graduates' job prospects as technological advances and changes in domestic and global markets transform professions in ways that reduce wages and cut jobs. Under these circumstances, it's natural to look for what may appear to be the most “practical” way out of the problem “Major in a subject designed to get you a job” seems the obvious answer to some, though this ignores the fact that many disciplines in the humanities characterized as “soft” often, in fact, lead to employment and success in the long run. Indeed, according to surveys, employers have expressed a preference for students who have received a broadly-based education that has taught them to write well, think critically, research creatively, and communicate easily.Moreover, students should be prepared not just for their first job, but for their 4th and 5th jobs, as there's little reason to doubt that people entering the workforce today will be called upon to play many different roles over the course of their careers. The ones who will do the best in this new environment will be those whose educations have prepared them to be flexible. The ability to draw upon every available tool and insight----picked up from science, arts, and technology—to solve the problems of the future, and take advantage of the opportunities that present themselves, will be helpful to them and the United States.56. What does the latest congressional report suggest?A) STEM-related subjects help students find jobs in the information society.B) The humanities and STEM subjects should be given equal importance.C) The liberal arts in higher education help enrich students' spiritual life.D) Higher education should be adjusted to the practical needs of society.57. What is the main concern of students when they choose a major?A) Their interest in relevant subjects.B) The academic value of the courses.C) The quality of education to receive.D) Their chances of getting a good job.58. What does the author say about the so called soft subjects?A) They benefit students in their future life.B) They broaden students' range of interests.C) They improve students' communication skills.D) They are essential to students' healthy growth.59. What kind of job applicants do employers look for?A) Those who have a strong sense of responsibility.B) Those who are good at solving practical problems.C) Those who are likely to become innovative leaders.D) Those who have received a well-rounded education.60. What advice does the author give to college students?A) Seize opportunities to tap their potential.B) Try to take a variety of practical courses.C) Prepare themselves for different job options.D) Adopt a flexible approach to solving problems.Passage TwoQuestions 61 to 65 are based on the following passage.Energy independence. It has a nice ring to it. Doesn't it? If you think so, you're not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession.“Energy independence” and its rhetorical (修辞的) companion “energy security” are, however, slippery concepts that are rarely though through. What is it we want independence from, exactly?Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that old from elsewhere.The first reason is that we need it to keep our economy running. Yes, there is a trickle(涓涓细流)of biofuel(生物燃料)available, and more may become available, but most biofuels cause economic waste and environmental destruction.Second, Americans have basically decided that they don't really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don't read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices, At the same time, we derive massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.61. What does the author say about energy independence for America?A) It sounds very attractive.B) It ensures national security.C) It will bring oil prices downD) It has long been everyone's dream.62. What does the author think of biofuels?A) They keep America's economy running healthily.B) They prove to be a good alternative to petroleum.。

Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3. It can be inferred the national from the passage that most people in the United States in 1955 viewed the national economy with an air of _________.a. confidenceb. confusionc. disappointmentd. suspicion4. Which of the following were LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Frmaersc. Politiciansd. Steelworkers5. The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案:cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案:ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案:bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案:cacbd六As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案:dadbc七In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing."A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案:abdcb八There are two factors which determine an individual's 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 reared. If an individual is handicapped envionmentally ,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 individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. 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 homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe 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 enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than 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.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案:bcbcc九As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "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. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry答案:dbdcd十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 lus 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 American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案:cabdd阅读理解限时训练与解析A(5minutes)I found out one time that doing a favor for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed(解散). As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized(强调)the fact that when people do something dishonest, they are really cheating(欺骗)themselves. She made me promise that I would think seriously(认真地)about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued(继续)to believe that I had cheated on the test.1. The story took place(发生)exactly ____ .A. in the teacher’s officeB. in an exam roomC. in the schoolD. in the language lab2. The girl wanted to borrow a pen, because ____ .A. she had not brought a pen with herB. she had lost her own on her way to schoolC. there was something wrong with her ownD. her own had been taken away by someone3. The teacher saw all this, so she asked the boy ____ .A. to go on writing his paperB. to stop whisperingC. to leave the room immediatelyD. to stay behind after the exam4. The thing(s) emphasized in her talk was(were) ____ .A. honestyB. sense of dutyC. seriousnessD. all of the above5. The boy knew everything ____ .A. the moment he was asked to stay behindB. when the teacher started talking about honestyC. only some time laterD. when he was walking out of the roomB(7minutes)Some kids start to drink alcohol (酒精) at a young age. They think it is part of becoming an adult. They also think drinking is not that bad because so many people do it. They feel it is not as bad as taking drugs (毒品). It is easy for kids to get liquor (酒精饮料)by using fake identification (伪造证件).Parents may start to notice a change in their child’s behavior if the child starts drinking. Kids who drink sometimes stop doing things they normally liked to do. They may keep telephone calls and meetings a secret and not want anybody to touch their things. They act moody (喜怒无常) and do not have the same eating and sleeping habits.Parents need to stay involved (牵涉) in their kids’lives. They should talk to their children about their problems to be aware of any changes.Parents can be the best protection. Children who get a lot of love can feel good about themselves. It helps them resist(抵抗)doing bad things even when other kids are doing them. Parents can also help set a good example by not drinking and driving. They can have firm rules in the home that everyone follows.Give the children good ideas on how to say “no”to drinking, even when they are at a party. Try not to overreact or panic (惊慌) if the child tries alcohol. How you handle it can affect their attitude. It may be helpful to talk to other parents about setting up curfews (宵禁令) and rules about parties or other events.1. Which of the following is NOT the reason why some kids have an early start of drinking?A. They want to show their maturity (成熟) by drinking alcohol.B. Drinking alcohol is much cooler than taking drugs.C. They are affected by many other people around them.D.

2019 年 6 月大学英语四级仔细阅读练习题三篇英语四级仔细阅读练习题(1)Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark-alive and conscious after trading his diseased heart for a metal-and-plastic pump-convinced the press, the public and many doctors that the future had arrived. It hadn 't. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them. Last week the agency cancelled its earlier approval, effectively banning ( 禁止) the device.The recall may hurt Symbion Inc., maker of the Jarvik-7, but it won 't end the request for an artificia l heart. One problem with the banned mode is that the tubes connecting it to an external power source createda passage for infection. Inventors are now working on new devices that would be fully placed, along with atiny power pack, in the patient 's chest. The first sample products aren 't expected for another 10 or20 years. But some people are already worrying that they 'll work—and that America 's overextended health —care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. If such expenditures ( 开支) cut into funding for more basic care, thenet effect could actually be a decline in the nation 's health.练习题:Choose correct answers to the question :1. According to the passage, the Jarvik-7 artificial heart proved to be .A. a technical failureB. a technical wonderC. a good life-saverD. an effective means to treat heart disease2. From the passage we know that Symbion Inc. ___ .A. has been banned by the government from producing artificial heartsB. will review the effects of artificial hearts before designing new modelsC. may continue to work on new models of reliable artificial heartsD. can make new models of artificial hearts available on the market in 10 to 20 years3. The new models of artificial hearts are expectedA. to have a working life of 10 or 20 yearsB. to be set fully in the patients chestC. to be equipped with an external power sourceD. to create a new passage for infection4. The word "them" in Line 7, Para. 2 refers to ___ .A. doctors who treat heart diseasesB. makers of artificial heartsC. America 's health -care programsD. New model of artificial hearts5. Some people feel that ____ .A. artificial hearts are seldom effectiveB. the country should not spend so much money on artificial heartsC. the country is not spending enough money on artificial heartsD. America 's health -care programs are not doing enough for the nation ' s health1. [A] 文章一开头说Jarvik-7 以前被认为是一大技术成就,但文章第1段倒数第2句中提到,美国食品与药品管理局得出结论, 认为这种仪器与其说是挽救生命, 不如说是将生命置于更加危险的境地。

Many even argue that each incoming freshman should have permanent access to his or hcr own microcomputer. What advantages do computers offer the college students?Any student who has used a word processor will know one compelling reason to use a computer: to write papers. Although not all students feel comfortable composing on a word processor, most find revising and editing much easier on it. One can alter, insert, or delete just by pressing a few keys, thus eliminating the need to rewrite or re-type. Furthermore, since the revision process is less burdensome, students are more likely to revise as often as is necessary to end up with the best paper possible. For these reasons, many freshmanEnglish courses require the use of a word processor.Computers are also useful in the context of language courses, where they are used to drill students in basic skills. Software programs reinforce ESL(English as a Second Language ) instruction, as well as instruction in French, German, Spanish, and other languages. By using these programs on a regular basis, students can improve their proficiency in a language while proceeding at their own pace.Science students take advantage of computers in many ways. Using computer graphic capabilities, for example, botany students can represent and analyze different plant growth patterns. Medical students can learn to interpret computerized images of internal body structures. Physics students can complete complex calculations far more quickly than they could without the use of computer.Similarly, business and accounting students find that computer spreadsheet programs are all but indispensable to many aspects of their work, while students pursuing careers in graphic arts. marketing, and public relations find that knowledge of computer graphic is important. Education majors learn to develop grading systems using computers, while social science students use computers for analyzing and graphically displacing their research results.It is no wonder, then, that educators support the purchase and use of microcomputers by students. A versatile tool, the computer can help students learn. And that is, after all, the reason for going to college.56. The word "literacy" (Line 1, Paragraph 1) means__________.A. the ability to read and writeB. the ability to useC. literatureD. the knowledge of language57. The main purpose of this passage is to __________.A. persuade the educators to increase computer use in their own classroomB. analyze advantages and disadvantages of computer use among college studentsC. identify some of the ways that computers benefit college studentsD. describe how computers can be used to teach foreign languages58. According to the author, a word processor can be used to __________.A. revise papersB. retype papersC. reduce the psychological burden of writing papersD. improve the writing skills of a student59.

Man-lifting kites were developed in ancient times,again by the Chinese, for getting information from walled cities and army camps.In fact,as recently as world2,German U-boats flew kites from their towers to lift people into the air to watch the lanD.These kites,which are no longer in existence,were made of light-weight cloth.They were much larger and stronger than the Chinese ones.Their design,however,was simply that of the cutter kite.Smaller in size,this type of kite is still very popular as a toy for children,being easy to make with a diamond-shapedframe,no wings and brown-paper covering.Box-kites are another type of kite found in toy shops today.The first box-kite,named for its box-like body,was developed in the nineteenth century to test theories of flight and this type of cotton-covered kite greatly assisted the success of early aeroplane.These kites are the ancestors of a heavier version of the box-kite,which consists of two main sections,placed side by side. Developed for the peacetime purpose of fishing in strong sea wind,it is the only modern kite described which has practical value.A long-lasting plastic material has to be used for this kite,which carries fishing lines.1.The ancient Chinese bird-kites were usually made of light frames covered with_____.A.silkB.paperC.clothD.plastic2.The kites used by German U-boats in would war2for the military purpose were made of_____.A.brown paperB.plastic materialC.light-weight clothD.traditional silk3.The ancient Chinese man-lifting kites were used_____.A.to carry ropes across rivers and valleysB.for the military purposeC.as toy for childrenD.for fishing in strong sea wind4.Which of the following statements is not ture?A.The frame of a kite is attached to long string held in the hand or woundon drum.B.The ancestor of the double box-kite.C.The cutter kite has a diamond-shaped body but no wings.D.The current folding kite is developed to test theories of flight.5.The best title for this may be______.A.The ancestors of modern kitesB.The history of the chinese kitesC.different types and uses of kitesD.the different between ancient and modern kites.二、完型填空完型填空(一)Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil andwater do.He finally concluded that the constituent 1must exist in the form of2particles or atoms andthat these3be completely mixed together in the4.This threw a new light in5laws of definiteproportions.It was6necessary to suppose that the atoms7 combinesintossmall groups of uniform8andso form more complex substance;

大学英语四级阅读习题及答案

大学英语四级阅读习题及答案

大学英语四级阅读习题(一)Acculturation, which begins at birth, is the process of teaching new generations of children the customs and values of the parents' culture. How people treat newborns, for example, can be indicative of cultural values. In the United States it is not uncommon for parents to put a newborn in a separate room that belongs only to the child. This helps to preserve parents' privacy and allows the child to get used to having his or her own room, which is seen as a first step toward personal independence. Americans traditionally have held independence and a closely related value, individualism, in high esteem. Parents try to instill these prevailing values in their children. American English expresses these value preferences: children should "cut the (umbilical) cord" and are encouraged not to be "tied to their mothers' apron strings." In the process of their socialization children learn to "look out for number one" and to "stand on their own two feet".Many children are taught at a very early age to make decisions and be responsible for their actions. Often children work for money outside the home as a first step to establishing autonomy. Nine-or ten-year-old children may deliver newspapers in their neighborhoods and save or spend their earnings. Teenagers (13 to 18 years) may baby-sit neighbors' homes in order to earn a few dollar a week. Receiving a weekly allowance at an early age teaches children to budget their money, preparing them for future financial independence. Many parents believe that managing money helps children learn responsibility as well as appreciate the value of money.21. According to this passage, the way people treat newborns_____.A) is a sign of their customsB) is an indication of their level of knowledgeC) symbolizes their social systemD) varies from culture to culture22. The expression, "to cut the cord", is used to show that_____.A) children don't like their parentsB) parents don't feel close to their childrenC) parents would not like to live together with their childrenD) independence from one's family is an important personal goal in USA23. Children who are "tied to the apron strings" _____.A) are caught in their mothers' apronsB) must always wear an apron when they eatC) are very dependent on their mothersD) are independent from their parents24. American people often let their children work for money outside the home at a very early age because _____.A) children have to earn money to help the familyB) they need more moneyC) they want them to begin establishing autonomyD) children have to save money for future use25. It can be inferred from this passage that _____.A) Americans are money loversB) Americans admire independenceC) Americans are good at decision-makingD) Americans are all responsible大学英语四级阅读习题答案1、A2、D3、C4、C5、B大学英语四级阅读习题(二)Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees.The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge.Observers noted down the referees’ errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number.The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的) distance is about 20 meters.There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second.If FIFA, football’s international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues.He also says that FIFA’s insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.21. The experiment conducted by the researcher was meant to________.A) review the decisions of referees at the 1998 World CupB) analyse the causes of errors made by football refereesC) set a standard for football refereeingD) reexamine the rules for football refereeing22. The number of refereeing errors in the experimental matches was ________.A) slightly above averageB) higher than in the 1998 World CupC) quite unexpectedD) as high as in a standard match23. The findings of the experiment show that ________.A) errors are more likely when a referee keeps close to the ballB) the farther the referee is from the incident, the fewer the errorsC) the more slowly the referee runs, the more likely will errors occurD) errors are less likely when a referee stays in one spot24. The word “officials” (Line 2, Para. 4) most probablyrefers to ________.A) the researchers involved in the experimentB) the inspectors of the football tournamentC) the referees of the football tournamentD) the observers at the site of the experiment25. What is one of the possible conclusions of the experiment?A) The ideal retirement age for an experienced football referee is 45.B) Age should not be the chief consideration in choosing a football referee.C) A football referee should be as young and energetic as possible.D) An experienced football referee can do well even when in poor physical condition.大学英语四级阅读习题答案21.

If you think a high-factor -sunscree(防晒霜)keeps you safe from harmful rays, you may be wrong.如果你认为防晒指数高的防晒霜能够使你免遭有害射线的辐射,那你可能就错了。

Research in this week’s Natureshows that while factor 50 reduces the number of melanomas(黑瘤)and delays their occurrence, it can’t prevent them.本周《自然》杂志的一项研究显示,尽管防晒指数为50的防晒霜能够减少黑瘤的数量,并延缓其出现,但是并不能阻止其产生。

Melanomas are the most aggressive skin cancers.黑瘤是最具侵犯性的皮肤癌。

You have a higher risk if you have red or blond hair, fair skin, blue or green eyes, or sunburn easily, or if a close relative has had one.如果你拥有红发或金发,浅色皮肤,蓝色或绿色眼睛,或者容易晒伤,又或者有近亲患此疾病,那么你患此病的风险就会相对较高。

Melanomas are more common if you have periodic intense exposure to the sun. Other skin cancers are increasingly likely with long term exposure.如果你周期性高强度地暴露于太阳下,黑瘤则会更为常见。

长期暴露于太阳下,患其他皮肤癌的可能性也会逐渐增加。

There is continuing debate as to how effective sunscreen is in reducing melanomas—the evidence is weaker than it is for preventing other typesof skin cancer.关于防晒霜在减少黑瘤方面的有效性的争论一直不断,相比防晒霜对于其他种类皮肤癌的预防作用,其对黑瘤的预防作用不太显著。

As you complete each step,you will enforce the belief in your ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.Long-range goals may be related to our dreams of the future.

Despit occasional alarms, the country escaped any postwar depression and livedin a state of boom. A n economic survey of the year 1955, a typical ye ar of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The productionof manufacturers was about 40 percent more than it had averaged in the years immediatelypent about 30billion dollars for new factories and following World War 2. The country’s business smachinery. National income available for spending was almost a third greater than it had been ithad been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars aday ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million peopleheld jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominousecho of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to theoppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3. It can be inferred the national from the passage that most people in the United States in1955 viewed the national economy with an air of _________.a. confidenceb. confusionc. disappointmentd. suspicion4. Which of the following were LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Frmaersc. Politiciansd. Steelworkers5. The passage states that incom available for spending in the U.S. was greater in 1955 thanin 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案:cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案:ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among femaleby nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) beganits current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案:bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to dietand forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillinto beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案:cacbdWhat is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be anoptimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greysand blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon asyou opened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge overthe Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up." "Among other facts" means______.a.besides other factsb.in regard to other factsc.not considering other factsd.according to other facts4.Which of the following is facts?a.People's preference of one colour to another is instinctb.People's preference of one colour to another is acquired as they grow up.c.More people happen to love brown because they saw something brown when they were bornd.Colours have little influence on our moods5.Those who committed suicide preferred the bridge over the Thames River near london to others because of _______.a.its shapeb.its structurec.its colourd.its building materials答案:bcaac十二Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands when you are eating? Should leave one in your lap,or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a wonman or offer their seat to a woman , and so will most Americans. Promptness is important both in England and in America. That is , if a dinner invitation is for 7 o'clock , the dinner guest either arrives closeto that time or calls up to explain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable-----especially if they are your guests. When the food was served , one of the guests strated to eat his peas with a knife . The other guests were amused or shocked , but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.1.If one has accepted a dinner invitation ,what should he do if he is tobe late for the dinner?a.He should find an excuseb.He should adk for excuse.c.He should say sorryd.He should telephone to explain his being late.2."It would have been bad manners to make his guests feel foolish or uncomfortable." "Bad manners " means ________.a.uglyb.dishonestc.impolited.shameful3.which of the following do you think is the best tiltle for this passage?a.Social Customs and Customsb.Social Lifec.American and British Customsd.Promptness Is Important4.According to the text, the best host_______.a.tries his best to make his guests feel comfortableb.makes his guests feel excitedc.tries to avoid being naughty to his guestsd.tries to avoid being foolish5.The author of this article may agree with which of the following?a.The guest who ate his peas with a knifeb.The other guests who were amused or shockedc.The host who picked up his knife and began eating in the same wayd.None of the above答案:dcaac十三New Orleans, Louisiana, was established as part of the French Empire in 1718.Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France,and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it , and the Americans under General And rew Jackson.The riverbed of the Mississippi is constantly silting and the river is now actually higher thanthe city. Levees hold back the river and giant pumps are used to move water from the city into the river.Although New Orleans haas beena part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which,form many years,was its only law.New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting facade of yesteryear, is a busy industrial and port city. Grain and coal come from the Midwest and foreigh cargoes are unloaded here. New Orleans is no longer a sleepy Southern town----but it's still fun to visit.1.What accounts for the levees and pumps in New Orleans?a.The Mississippi frequently floods the city.b.The riverbed has raised inthe past 200 years.c.The torrential rains flood the city frequently.d.The high humidity cannot otherwise be comtrolled.2.The battle of New Orleans was fought by jackson against______.a.Franceb.Britainc.Spaind.The North3.The Code Napoleon was _______.a.an agreement to sell Louisianab.a body of lawsc.a city pland.a military code for the army4.Which of the following elements does not apply to the attiude of the inhabitants of New Orleans?a.Pride in their French heritage.b.A desire to retain picturesque colonial buildings.c.A refusal to engage in trade and commerced.A praising of Dixieland Jazz.5.Tourists visiting New Orleans are surprised to encounter_____.a.Creole foodb.Dixieland jazzc.bustling cityd.authentic colonial homes答案:bbbcc十四The United States is on the verge of losing its leading place in the world's technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S. scientists and engineers.Since 1976,employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-olds--the near term source of future PH.D.s-is declining. Further adding to the problem is the increased competition for these candidates from other fields-law,medicine,business,etc. While the number of U.S. PH.D.s in science and engineering declines,the award of PH.D.s to foreign nationals is increasing rapidly.Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor's and Master's degree holders. Too often, promising PH.D.candidates, confronting the cost and financial sacrifice of pursuing their education,find the attraction of industry irresistible.1.The U.S.will come to lose its leading place in technology probably because ________.a. the number of PH.D. degree holders is decliningb. the number of scientists and engineers is decreasingc. the number of 22-year-ilds is decliningd. scientists and engineers are not employed2.The field of science and engineering is facing a competition from ________ .a. technologyb. foreign nationalsc. such fields as law, medicine and businessd. postgraduatesrge-scale enterprises now need _______.a. bright graduates and postgraduatesb. new inventionsc. advanced technologyd. engineers4.Many promising postgraduates are unwilling to pursue a PH.D. degree because _________.a. they are not encouraged to be engaged in scienceb. industry does not require PH.D. holdersc. they have financial difficultiesd. they will spend much time and energy completing PH.D.5.PH.D. candidates "find the attraction of industry irresistible" means that _________.a. they find industry is attracting more and more college studentsb. they don't think they can prevent themselves from working for industryc. they cannot resist any attraction from all sidesd. they cannot work for industry any longer答案:bcadb十五Newdays,a standard for measuring power has changed.These changes foretell a new standard for measuring power.No longer will a nation's political influence be based solely on the strength ofits military forces. Of course, military effectiveness will remain a primary primary measure of power.But political influence is also closely tied to industrial competitiveness. It's often said that without its military the Soviet Union would really be a third-world nation. The new standard ofopwer and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.America must recognize this new course of events. Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Our industrial prowess over most of this period was unchallenged. It is ironic that it is just this prowess that has enabled other countries to prosper and in turn to threaten our industrial leadership.The competitiveness of America's industrial base is an issue bigger than the Department of Defense and is going to require the efforts of the major institutional forces in our society-government,industry,and education. That is not to say that the Defense Department will not be a strong force in the process because we will. But we simply cannot be, nor should we be, looked upon by others as the savior of American industry.1. Now a nation's political influence depends on _________.a. the strength of its military forcesb. its ability to compete in industryc. economic marketsd. both a and b2. The Soviet Union was not listed as a third-world nation just because of _________.a. its powerful military forcesb. its vast landc. its industrial competitivenessd. its contributions to world peace3. The author indicates that ______ is threatening American political power.a. other countriesb. the declining U.S. industrial basec. a new standard for measuring powerd. less advanced technology4. America succeeded in shaping world events over past 40 years probably because of ___________.a. its ability to adapt technologyb. its ability to take advantage of the capabilities of its peoplec. its ability to compete in the world marketsd. both a and b5. The purpose of writing this article is __________.a. to draw the readers' attention to a new standard for measuring powerb. to demonstrate American political influence in the worldc. to emphasize that efforts must be made to strengthen the declining U.S. industrial based. to show American industrial prowess答案:dabdc。

2014年6月英语四级仔细阅读真题(总三套题)及答案

2014年6月英语四级仔细阅读真题(总三套题)及答案

2014年6月英语四级仔细阅读真题(第一套)及答案Passage OneQuestions 56 to 60 are based on the following passage.When young women were found to make only 82 percent of what their male peers do just one year out of college,many were at a loss to explain it。

All the traditional reasons put forward to interpret the pay gap-that women fall behind when they leave the workforce to raise kids,for example, or that they don’t seek as many m anagement roles—failed to justify this one. These young women didn’t have kids yet. And because they were just one year removed from their undergraduate degrees,few of these women yet had the chance to go after (much less decline)leadership roles。

But there are other reasons why the pay gap remains so persistent。

The first is that no matter how many women may be getting college degrees,the university experience is still an unequal one. The second is that our higher education system is not designed to focus on the economic consequences of our students' years on campus.Now that women are the majority of college students and surpass men in both the number of undergraduate and advanced degrees awarded, one might think the college campus is a pretty equal place。

CET4 阅读(一)Passage 1Oceanography has been defined as 'The application of all sciences to the study of the sea'.Before the nineteenth century, scientists with an interest in the sea were few and far between. Certainly Newton considered some theoretical aspects of it in-his writings, but he was reluctant (不愿意) to go to sea to further his work.For most people the sea was remote, and with the exception of early intercontinental travellers or others who earned a living from the sea, there was little reason to ask many questions about it, 1et alone to ask what lay beneath the surface. The first time that the question 'What is at the bottom of the oceans?' had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed.The engineers had to know the depth profile (起伏形状)of the mute to estimate the length of cable that had to be manufactured.It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s,Maury had been responsible for encouraging voyages during which soundings(测深) were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea. The cable was laid, but not until 1866was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts ofthe sea. Within a few years oceanography was under way. In 1872Thomson led a scientific expedition (考察), which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.1. The passage implies that the telegraph cable was built mainly_____A)for oceanographic studies C)for business considerationsB)for military purposes D)for investigating the depths of the oceans2.It was_____ that asked Maury for help in oceanographic studies.A)the American Navy B)some early intercontinental travellersC)those who earned a living from the seaD)the company which proposed to lay an undersea cable3.The aim of voyages Maury encouraged in the 1840s was____A)to make some sound experiments in the oceansB)to collect samples of sea plants and animalsC)to estimate the length of cable that was to be madeD)to measure the depths of two oceans4.'Defied' in the 5th paragraph probably means_____A)'doubted' C)'challenged' B)'gave proof to' D)'agreed to'5.This passage is mainly about________A)the beginnings of oceanographyB)the laying of the first undersea cableC)the investigation of ocean depthsD)the early intercontinental communications6.The author's attitude in this passage is _____A)critical B)objective C)warmhearted D)sadPassage 2The speaker, a teacher from a community college, addressed a sympathetic audience. Heads nodded in agreement when he said, "High school English teachers are not doing their jobs." He described the inadequacies of his students, all high school graduates who can use language only at a grade 9 level. I was unable to determine from his answers to my questions how this grade 9 level had been established.My topic is not standards nor its decline (降低).What the speaker was really saying is that he is no longer young; he has been teaching for sixteen years, and is able to think and speak like a mature adult.My point is that the frequent complaint of one generation about the one immediately following it is inevitable. It is also human nature to l∞k for the reasons for our dissatisfaction. Before English became a school subject in the late nineteenth century, it was difficult to find the target of the blame for language deficiencies(缺陷).But since then, English teachers have been under constant attack.The complainers think they have hit upon an original idea. As their own command of the language improves, they notice that young people do not have this same ability. Unaware that their own ability has developed through the years, they assume the new generation of young people must be hopeless in this respect. To the eyes and ears of sensitive adults. The language of the young always seems inadequate.Since this concern about the decline and fall of the English language is not perceived as a generational phenomenon but rather as something new and peculiar to today's young people, it naturally follows that today 's English teachers cannot be doing their jobs. Otherwise, young people would not commit offenses against the language.1.The speaker the author mentioned in the passage believed thatA) the language of the younger generation is usually inferior to that of the older generationB) the students had a poor command of English because they didn't work hard enoughC) he was an excellent language teacher because he had been teaching English for sixteen yearsD) English teachers should be held responsible for the students, poor command of English2.In the author's opinion, the speakerA) gave a correct judgement of the English level of the studentsB) had exaggerated the language problems of the studentsC) was right in saying that English teachers were not doing their jobsD) could think and speak intelligently3.The author's attitude towards the speaker's remarks is________ .A) neutral C) critical B) positive D)compromising4.It can be concluded from the passage thatA) it b justifiable to include English as a school subjectB) the author disagrees with the speaker over the standard of English at Grade9levelC) English language teaching is by no means an easy jobD) Language improvement needs time and effort5.In the passage the author argues thatA) it is unfair to blame the English teachers for the language deficiencies of the studentsB) young people would not commit offences against the language if the teachers did their jobs properlyC) to eliminate language deficiencies one must have sensitive eyes and earsD) to improve the standard of English requires the effort of several generations 答案:Passage 1: CDDCABPassage 2: DBCDA。

Conducting those strategies needs to consider both personal and official will.C.Carrying out those strategies needs both individual and govemmental support.D.Either individual or government can carry out those strategies.57.What have high.income countries done to smoking?A. Banned smoking in the public and reduced tobacco taxes.B.Banned public smoking and established tobacco taxes.C. Dropped smoking rates and banned smoking in public.D. Dropped smoking rates and lowered tobacco taxes.58.What is the authors suggestion to sodium consumption?A.Eat lemons instead of excessive salt to cut down sodium consumption.B.Take in as less salt as possible for the sake of health.C. Take in at least 800mg of salt every day.D.Never take in salt but citric acid to keep fit.59.What carl you learn about hypertension from the passage?A. Moderate amount of alcoholis good for blood pressure contr01.B.American people have a less opportunity to develop hypertension.C.Regular blood pressure monitoring can reduce the risk of diabetes.D.Controlling blood pressure properly can reduce the risk of stroke and heart disease.60.What should we do to address diabetes?A.Keep a low.sugar diet.B.Take physical exercise.C.

大学英语四级仔细阅读专项强化真题试卷1(题后含答案及解析)

大学英语四级仔细阅读专项强化真题试卷1(题后含答案及解析) 题型有:1.The latest in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect. According to a newly published study, cats seem to be able to predict the location of hiding prey (猎物) using both their ears and an inborn (天生的) understanding of how the physical world works. In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a team member shook. Some containers rattled (发出响声) : others did not. When the container was tipped over, sometimes an object fell out and sometimes it didn’ t. It turns out that the cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected. “Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects,”lead researcher Saho Takagi says in a press release. The researchers conclude that cats’ hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing. Scientists have explored this idea with other endearing creatures: babies. Like cats, babies appear to engage in what’s called “preferential looking”—looking longer at things that are interesting or unusual than things they perceive as normal. When babies’expectations are violated in experiments like the ones performed with the cats, they react much like their animal friends. Psychologists have shown that babies apparently expect their world to comply with the laws of physics and cause and effect as early as two months of age. Does the study mean that cats will soon grasp the ins and outs of cause and effect? Maybe. Okay, so cats may not be the next physics faculty members at America’ s most important research universities. But by demonstrating their common sense, they’ ve shown that the divide between cats and humans may not be that great after all.1.What do we learn from a newly published study about cats?A.They can be trained to understand the physical world.B.They know what kind of prey might be easier to hunt.C.They have a natural ability to locate animals they hunt.D.They are capable of telling which way their prey flees.正确答案:C解析:细节题。

2023上半年英语四级仔细阅读模拟题及答案1

2023上半年英语四级仔细阅读模拟题及答案12023上半年英语四级仔细阅读模拟题及答案(1)There is evidence that the usual variety of high blood pressure is, in part, a familial disease. Since families have similar genes as well as similar environments, familial diseases could be due to shared genetic influences, to shared environmental factors, or to both. For some years, the role of oneenvironment factor commonly shared by families, namely dietary salt (i.e., sodium chloride), has been studied at Brookhaven National Laboratory. These studies suggest that long excess salt intake can lead to high blood pressure in man and animals. Some individuals, however, and some rats consume large amounts of salt without developing high blood pressure. No matter how strictly all environmental factors were controlled in these experiments, some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death. These marked variations were interpreted to result from differences in genetic constitution.By mating long successive generations of those animals that failed to develop hypertension from salt intake, a resistant strain (the " R" strain) has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly. In contrast, by mating only animals that quickly develop hypertension from salt, sensitive strain (the "S" strain) has also been developed.The availability of these two strains permits investigations possible. They provide a plausible laboratory model on which to investigate some clinical aspects of the human hypertension. More important, there might be the possibility of developing methods by which genetic susceptibility (敏感性) of human beings to high blood pressure can be defined without waiting for its appearance. Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.21. The study of the effects of salt on high blood pressure was carried out_______.A. as members of the same family tend to use similar amounts of saltB. to explore the long-term use of a sodium based substanceC. because it was proven that salt caused high blood pressureD. because of the availability of chemically pure salt and its derivatives22. The main difference between "S" and "R" rats is their_______.A. need for sodium 22B. rate of matingC. reaction to saltD. type of blood23. We can infer from the article that sodium 22 can be used to_______.A. control high blood pressureB. cure high blood pressure caused by saltC. tell the "S" rats from the "R" ratsD. determine what a sodium chloride metabolism is like24. The most beneficial results of the research might be_______.A. development of diets free of saltB. an early cure for high blood pressureC. control of genetic agents that cause high blood pressureD. the early identification of potential high blood pressure victims25. Which of the statements best relates the main idea of this article?A. When salt is added rats and human beings react similarly.B. The near future will see a cure for high blood pressure.C. The medical field is desperately in need of research.D. A tendency toward high blood pressure may be a hereditary factor.答案21. A 22. C 23. D 24. D 25. D。
