2020年英语六级阅读理解预测题及答案(4)

We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could mot. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.

Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don’t develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists’ suspici ons that the experience or perception of helplessness is one of the most harmful factors in depression.

One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the University of Rochester

School of Medicine conditioned (使形成条件反射) mice to avoid saccharin (糖精) by simultaneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier conditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.

11. Laudenslager’s experiment showed that the immune system of those rats who could turn off the electricity

________.

A) was strengthened

B) was not affected

C) was altered

D) was weakened

12. According to the passage, the experience of helplessness causes rats to ________.

A) try to control unpleasant stimuli

B) turn off the electricity

C) behave passively in controllable situations

D) become abnormally suspicious

13. The reason why the mice in Ader’s experiment avoided saccharin was that ________.

A) they disliked its taste

B) it affected their immune systems

C) it led to stomach pains

D) they associated it with stomachaches

14. The passage tells us that the most probable reason

for the death of the mice in Ader’s experiment was that

________.

A) they had been weakened psychologically by the saccharin

B) the sweetener was poisonous to them

C) their immune systems had been altered by the mind

D) they had taken too much sweetener during earlier conditioning

15. It can be concluded from the passage that the immune systems of animals ________.

A) can be weakened by conditioning

B) can be suppressed by drug injections

C) can be affected by frequent doses of saccharin

D) can be altered by electric shocks

2017年6月英语六级阅读真题及答案第1套选词填空 After becoming president of Purdue University in2013, Mitch Daniels asked the faculty to prove that their students have actually achieved one of higher education’s most important goals: critical thinking skills. Two years before, a nationwide study of college graduates had shown that more than a third had made no 26 gains in such mental abilities during their school years. Mr. Daniels needed to__27__ the high cost of attending Purdue to its students and their families. After all, the percentage of Americans who say a college degree is "very important" has fallen 28 in the last 5-6 years. Purdue now has a pilot test to assess students' critical thinking skills. Yet like many college " such as a graduate's ability to investigate and reason. However, the professors need not worry so much. The results of a recent experiment showed that professors can use __31__ metrics to measure how well students do in three key areas: critical thinking, written communication, and quantitative literacy. Despite the success of the experiment, the actual results are worrisome, and mostly __32__ earlier studies. The organizers of the experiment concluded that far fewer students were achieving high levels on critical thinking than they were doing for written communication or quantitative literacy. And that conclusion is based only on students nearing graduation.

Although many researchers broadly agree that public access to raw data would accelerate science, most are reluctant to post the results of their own labors online. Some communities have agreed to share online—geneticists, for example, post DNA sequence sat the GenBank repository (库) , and astronomers are accustomed to accessing images of galaxies and stars from, say, the Sloan Digital Sky Survey, a telescope that has observed some500 million objects—but these remain the excepti on, not the rule. Historically, scientists have objected to sharing for many reasons: it is a lot of work; until recently, good databases did not

We say we want only the best, but we strangely enjoy junk food. We’re 2 with health and weight loss but face an unprecedented epidemic of obesity(肥胖). Perhaps the 3 to this ambivalence(矛盾情结) lies in our history. The first Europeans came to this continent searching for new spices but went in vain. The first cash crop(经济作物) wasn’t eaten but smoked. Then there was Prohibition, intended to prohibit drinking but actually encouraging more 4 ways of doing it. The immigrant experience, too, has been one of inharmony. Do as Romans do means eating what “real Americans” eat, but our nation’s food has come to be 5 by imports—pizza, say, or hot dogs. And some of the country’s most treasured cooking comes from people who arrived here in shackles. Perhaps it should come as no surprise then that food has been a medium for the nation’s defining struggles, whether at the Boston Tea Party or the sit ins at southern lunch counters. It is integral to our concepts of health and even morality whether one refrains from alcohol for religious reasons or evades meat for political 6 . But strong opinions have not brought 7 . Americans are ambivalent about what they put in their mouths. We have become 8 of our foods, especially as we learn more about what they contain.

2018年12月英语六级阅读练习题及答案（五） Everyone has a moment in history, which belongs particularly to him. It is the moment when his emotions achieve their most powerful sway over him, and afterward when you say to this person ―the world today‖ or ―life‖ or ―reality‖ he will assume that you mean this moment, even if it is fifty years past. The world, through his unleashed(释放的)emotions, imprinted itself upon him, and he carries the stamp of that passing moment forever. For me, this momentfour years in a moment in historywas the war. The war was and is reality for me. I still instinctively live and think in its atmosphere. These are some of its characteristics: Franklin Delano Roosevelt is the president of the United States, and he always has been. The other two eternal world leaders are Winston Churchill and Joseph Stalin. America is not, never has been, and never will be what the song and poems call it, a land of plenty. Nylon, meat, gasoline, and steel are rare. There are too many jobs and not enough workers. Money is very easy to earn but rather hard to spend, because there isnt very much to buy. Trains are always late and always crowded with ―service men‖. The war will always be fought very far from America, and it will never end. Nothing in America stands still for very long, including the people who are

Passage One Questions 52 to 56 are based on the following passage. The 35 percent of African-American youth living in poverty are the most visible victims of what is often called the achievement gap. But black children of all socioeconomic levels perform worse on national tests and graduate in fewer numbers than their white middle-class peers. A study by the U.S. Department of Education’s National Center for Education Statistics found that African-American students scored, on average, 26 points lower than white students on their reading and math tests. Some say, as Harvard psychologist Richard J. Herrnstein and American Enterprise Institute political scientist Charles Murray did in their 1994 book, The Bell Curve, that the cause is genetic. And though The Bell Curve has been discredited in scientific circles, the idea that IQ is somehow linked to race has been slow to retreat. Others, like Cornell University researchers Gary Evans and Michelle Schamberg, believe that “physiological stress is a plausible model for how poverty could get into the brain and eventually interfere with achievement,” as they wrote in Proceedings of the National Academy of Sciences. Our best efforts at narrowing the gap nationally — think No Child Left Behind —haven’t worked. But locally, there are now signs of hope. At the Harlem

大学英语六级阅读模拟试题及答案 第一篇 A scientific panel convened by the World Health Organization recommended guidelines on Friday for doctors conducting clinical studies of SARS patients. The panel urged doctors to apply the guidelines in analyzing the masses of potentially useful information about various therapies that were collected in this year’s epidemic. Much of that information has not been published or analyzed. “It is a matter of urgency to get better analysis and review,” said Dr. Simon Mardel, a WHO official who led the two-day meeting that ended on Friday. He said thousands of potential therapies and compounds had been tested so far as researchers try to determine treatments for SARS, or severe acute respiratory syndrome. “We recognize that having no treatment for SARS is hindering our ability to control an epidemic in so many ways.” He said. In the epidemic earlier this year, various treatments, like drugs to fight the virus or strengthen the immune system, as well as traditional Chinese medicine, were delivered under emergency conditions, in widely different settings and countries to patients suffering from varying stages of the illness. Those conditions—generally without standardized measurements or controlled situations—have made it hard to interpret results. Standard supportive therapy like nursing, and in severe cases the use of mechanical respirators（呼吸器）to help patients breathe, is the mainstay（主要支持）of SARS care, and helped many patients survive. But doctors still do not know how best to treat SARS patients who have breathing difficulties. Dr. Mardel said. One method is invasive ventilation. A second method involves blowing oxygen into the lungs through a mask. Both carry the risk of transmitting the virus to hospital employees. Without proper analysis, the panel was unable to say definitively which treatment worked best, or which caused the most harm. “There is a lack of shared information,” Dr. Mardel said, noting that a lot of data have not been published. The panel also agreed on guidelines that would allow doctors to conduct quick and safe clinical trials, a process that generally takes years to complete. The world Health Organization, a United Nations agency did not release the guidelines. Dr. Mardel said they were flexible because no one knew where, when and in what setting SARS would return. Experts in many countries have already listed the treatments they want to test, and the health agency is leaving these decisions to individual nations. 1. Guidelines recommended by the scientific panel can be used for _____. A. gathering potentially useful information about various therapies collected B. conducting clinical studies of SARS patients C. determining treatment for SARS D. publishing all the information about SARS

洛基英语，中国在线英语教育领导品牌 There are spectacular differences between financial markets on the Continent of Europe on the one hand，and in Britain on the other hand. In Britain，the market is really the City of London. It is a free market，and it controls most of the flow of savings to investment. On the Continent，either a few banks or government officials direct the flow of funds to suit their economic plans. In Germany the flow is directed by all-powerful banks. In Britain there is more free interplay of market forces and far fewer regulations，rules and “red tape”。A French banker summed it up this way：“On the Continent you can‘t do anything unless you’re been told you can；in England on the other hand you can do everything as long as you haven‘t been told not to.” There are many basic reasons for these differences. One is that Continental savers tend to prefer gold，cash or short-term assets. They invest only 10% of their savings in institutions like pension funds or insurance companies. But in Britain 50% of savings goes to them，and they，in turn，invest directly in equity market. A far lower proportion of savings is put in the banks in the form of liquid assets than on the Continent. Continental governments intervene directly or through the banks to collect savings together and transform them into medium or long-term loans for investment. The equity market is largely bypassed. On the Continent economic planning tends to be far more centralized than in Britain. In Britain it is possible to influence decisions affecting the country‘s economy from within the City. It attracts a skilled and highly qualified work force. In France，on the other hand，an intelligent young man who wants a career in finance would probably find the civil service more attractive. In Britain the market，or more accurately，money tends to be regarded as an end in itself. On the Continent it is regarded as a means to an end：investment in the economy. To British eyes continental systems with possible exception of the Dutch seem slow and inefficient. But there is one outstanding fact the City should not overlook. Britain‘s growth rates and levels of investment over the last ten years have been much lower than on the Continent. There are many reasons for this，but the City must take part of the blame. If it is accepted that the basic function of a financial market is to supply industry and commerce with finance in order to achieve desired rates of growth，it can be said that by concentrating on the market for its own sake the City has tended to forget that basic function. 1.What is the best title of the passage？ A.Savings and the Growth Rate. B.Banking and Finance：Two Different Realities. C.Monetary Policy in Britain. D.The European Continent and Britain. 2.What seems to be the most fundamental reason for this difference？ A.The British tend to regard money as an end，whereas Continental European

2018年6月大学英语六级考试仔细阅读真题解析（卷二） Section C Directions:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage One Questions 46 to 50 are based on the following passage. Economically speaking, are we better off than we were ten years ago? Twenty years ago? In their thirst for evidence on this issue, commentators seized on the recent report by the Census Bureau, which found that average household income rose by 5.2% in 2015. Unfortunately, that conclusion puts too much weight on a useful, but flawed and incomplete, statistic. Among the more significant problems with the Census’s measure are that: 1) it excludes taxes, transfers, and compensation like employer-provided health insurance; and 2) it is based on surveys rather than data. Even if precisely measured, income data exclude important determinants of economic well-being, such as the hours of work needed to earn that income. While thinking about the question, we came across a recently published article by Charles Jones and Peter Klenow, which proposes an interesting new measure of economic welfare. While by no means perfect, it is considerably more comprehensive than average income, taking into account not only growth in consumption per person but also changes in working time, life expectancy, and inequality. Moreover, it can be used to assess economic performance both across countries and over time. The Jones-Klenow method can be illustrated by a cross-country example. Suppose we want to compare the economic welfare of citizens of the U.S. and France in 2005. In 2005, as the authors observe, real consumption per person in France was only 60% as high as the U.S., making it appear that Americans were economically much better off than the French on average. However, that comparison omits other relevant factors: leisure time, life expectancy, and economic inequality. The French take longer vacations and retire earlier, so typically work fewer hours; they enjoy a higher life expectancy, presumably reflecting advantages with respect to health care, diet, lifestyle, and the like; and income and consumption are somewhat more equally distributed there than in the U.S. Because of these differences, comparing France’s consumption with the U.S.’s overstates

2010 年6 月六级真题 Passage One 发达国家中只有两个国家不能保证提供用于照料新生儿的带薪休假。去年春天，这两个国家中的一个——澳大利亚——放弃了这种令人质疑的殊荣，建立了自2011 年起开始实施的带薪家庭休假制。在美国这并没有成为新闻，我并不感到意外——现在我们是唯一没有这项政策的富有国家。 美国确实有一个明确的家庭政策，这就是于1993 年通过的《家庭和医疗休假法》。它规定要照料新生儿或处理家庭医疗问题的工人有资格享受时间长达12 个星期的不带薪休假。尽管此法案带来的利益不明显，但当时商务部和其他一些商业团体都极力反对，称其为“政府负责的人事管理”和“危险的先例”。事实上，民主党领袖一直都致力于将能促进工作与家庭关系平衡的措施形成法律条文，但每一次的努力都遭到了商业团体的强烈反对。 正如耶鲁大学法学教授Anne Alstott 所辩解的那样，要肯定父母关爱的作用就要将家庭定义为一种社会商品，从某种意义上讲，社会要为此埋单。在她的书《无路可走：父母对孩子的亏欠以及社会对家长的亏欠》中，她认为父母在生活的多个方面都肩负重担：在谈到孩子的话题时，父母们“无路可走”：“社会希望也需要家长们能不间断地照看好他们的孩子，而且是人类用以开发智力、培养情感和树立道德的那种深度的、亲密无间的照看。社会还希望并需要父母们能坚守这一角色，18 年如一日，如有必要，甚至还可以更长。” 大部分父母出于爱都会照顾孩子，不照顾孩子的父母则会受到公众的处罚。换句话说，父母们所做的一切都是这个国家所密切关注的问题，原因很明显，照顾孩子不仅从道德上来说是迫切的而且对这个社会的未来至关重要。国家在大多数保障儿童福利的家庭法律中都认可了这一点，而父母们在履行社会所强加给他们的、会改变其命运的义务时得到的帮助却甚少。把养育孩子视为个人选择、集体没有责任的做法不仅仅忽视了良好家庭教育所产生的社会效益，而且会抹杀这部分社会效益，因为当今天的孩子成为明天的具有生产力的公民时这部分社会效益会属于整个社会。实际上，据估计父母对孩子投入的价值，包括时间和金钱的投入（包括失去的薪水）相当于国内生产总值的20%—30%。如果这些投入能够产生巨大的社会效益——很明显能产生——那么为家庭提供更多的社会支持所带来的效益将会更加显而易见。 Passage Two 塔夫茨大学公民学习和参与信息研究中心(CIRCLE)一份新的调查显示，现在有比以前更多的年轻人参与投票选举，美国发展中心2008 年的一份调查也表明越来越多的年轻选民和活动家开始支持传统的自由事业。但要看出这些调查数字在现实生活中的意义并非易事。在总统竞选期间，巴拉克·奥巴马以希望和改变为宣传口号组成了不同种族之间和不同意识形态之间人们的联盟。当新一届政府执政下的现实生活步入正轨的时候，有些支持者可能会大失所望。随着国家进一步走入奥巴马执政时代，参与政治的年轻人是会继续支持奥巴马及其施政议程还是会渐行渐远？ “O（奥巴马的简称）一代”是《新闻周刊》新开的一个博客，致力于记录那些支持奥巴马的年轻人的生活。“O 一代”的作者们想就上面的问题做出回答。未来的三个月，Michelle Kremer 和其他11 位年龄从19 岁到34 岁不等的奥巴马支持者将会用博客来记录美国社会的主流生活，一个不同之处在于：通过将他们所有的观点和经历与新任总统及其领导下的政府紧密结合，这些博客作者试图开启一场对话，探讨在当今美国，年轻并且在政治方面活跃到底意味着什么。24 岁的Malena Amusa 是该博客的一位作者，也是来自圣路易斯的一位舞者，她将这一项目看做是即时记录历史的一种方式。Amusa 今年春天为了完成其著作前往印度，后来又去塞内加尔教授英语，她和她的朋友一直在谈论奥巴马当政会如何改变他们的日常生活，她希望把其中的一些观点和她的全球性视角写到帖子里。她很兴奋，要看清楚世界，“我不必等上15 年”，她这样解释说。 Henry Flores 是圣玛丽大学的政治学教授，他将年轻一代的政治力量归因于他们对科技的拥护。“网络使他们接触到更多的思想，”他说，“不同地区想法相同的人们就会聚到一起。”这正是“O 一代”博主们所期待的事情。结果可能会出现一群年轻人，就像他们在二战后生育高峰期出生的父母一样，伴随一种强烈的目的感而成长，他们也会改变此前从“X 一代”人身上所继承下来的冷漠形象。由一群普通但有抱负的年轻人来管理博客是个不小的挑战，但“O 一代”的成员能胜任这项任务。

2011年6月大学英语六级真题及答案 Part IV Reading Comprehension (Reading in Depth) (25 minutes) Section A Directions: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2. Questions 47 to 51 are based on the following passage. How good are you at saying "no"? For many, it's surprisingly difficult. This is especially true of editors, who by nature tend to be eager and engaged participants in everything they do. Consider these scenarios: It's late in the day. That front-page package you've been working on is nearly complete; one last edit and it's finished. Enter the executive editor, who makes a suggestion requiring a more-than-modest rearrangement of the design and the addition of an information box. You want to scream: "No! It's done!" What do you do? The first rule of saying no to the boss is don't say no. She probably has something in mind when she makes suggestions, and it's up to you to find out what. The second rule is don't raise the stakes by challenging her authority. That issue is already decided. The third rule is to be ready to cite options and consequences. The boss's suggestions might be appropriate, but there are always consequences. She might not know about the pages backing up that need attention, or about the designer who had to go home sick. Tell her she can have what she wants, but explain the consequences. Understand what she's trying to accomplish and propose a Plan B that will make it happen without destroying what you've done so far. Here's another case. Your least-favorite reporter suggests a dumb story idea. This one should be easy, but it's not. If you say no, even politely, you risk inhibiting further ideas, not just from that reporter, but from others who heard that you turned down the idea. This scenario is common in newsrooms that lack a systematic way to filter story suggestions. Two steps are necessary. First, you need a system for how stories are proposed and reviewed. Reporters can tolerate rejection of their ideas if they believe they were given a fair hearing. Your gut reaction (本能反应) and dismissive rejection, even of a worthless idea, might not qualify as systematic or fair. Second, the people you work with need to negotiate a "What if ...?" agreement covering "What if my idea is turned down?" How are people expected to react? Is there an appeal process? Can they refine the idea and resubmit it? By anticipating "What if...?" situations before they happen, you can reach understanding that will help ease you out of confrontations. 47. Instead of directly saying no to your boss, you should find out __________. 48. The author's second warning is that we should avoid running a greater risk by __________. 49. One way of responding to your boss's suggestion is to explain the __________ to her and offer an alternative solution. 50. To ensure fairness to reporters, it is important to set up a system for stories to __________. 51. People who learn to anticipate "What if...?" situations will be able to reach understanding and avoid __________. Section B Directions:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage One Questions 52 to 56 are based on the following passage. At the heart of the debate over illegal immigration lies one key question: are immigrants good or bad for the economy? The American public overwhelmingly thinks they're bad. Yet the consensus among most economists is
