Passage Three
Most growing plants contain much more water than all other materials combined. (73) C. R. Barnes has suggested that it is as proper to term the plant a water structure as to call a house composed mainly of brick a brick building. Certain it is that all essential processes of plant growth and development occur in water. The mineral elements from the soil that are usable by the plant must be dissolved in the soil solution before they can be taken into to the root. They are carried to all parts of the growing plant and are built into essential plant material while in a dissolved state. The carbon dioxide(二氧化碳）from the air may enter the leaf as a gas but is dissolved in water in the leaf before it is combined with a part of the water to from simple sugars- the base material from which the plant body is mainly built. Actively growing plant parts are generally 75 to 90 percent water. Structural parts of plants, such as woody stems, due to longer actively growing, may have much less water than growing tissues.
The actual amount of water in the plant at any one time, however, is only a very small part of what passage through it during its development, The processes of photosynthesis (光合作用), by which carbon dioxide and water are combined-in the presence of chlorophyll (叶绿素）and with energy derived from light-to from sugars, require that carbon dioxide from the air enter the plant. This occurs mainly in the leaves. The leaf surface is not solid but contains great numbers of minute openings, through which the carbon dioxide enters. The same structure that permits the one gas to enter the leaf, however, permits another gas-water vapor-to be lost from it. Since carbon dioxide is present in the air only in trace quantities (3 to 4 parts in 10,000 parts of air) and water vapor is near saturation in the air only in the air spaces within the leaf at 80°H, saturated air would contain about 186 parts of water vapor in 10,000 parts of air), the total amount of water vapor lost is many times the carbon dioxide intake. Actually, because of wind and other factors, the loss of water in proportion to carbon dioxide intake may be even greater than the relative concentrations of the two gases. Also, not all of the carbon dioxide that enters the leaf is synthesized into carbohydrates (碳水化合物).
31. A growing plant needs water for all of the following except _____.
A. forming sugars
B. sustaining woody stems
C. keeping green
D. producing carbon dioxide
32. The essential function of photosynthesis in terms of plant needs is _____.
A. to from sugars
B. to derive energy from light
C. to preserve water
D. to combine carbon dioxide with water
33. The second paragraph use facts to develop the essential idea that _____.
A. a plant efficiently utilizes most of the water it absorbs
B. carbon dioxide is the essential substance needed for plant development
C. a plant needs more water than is found in its composition
D. the stronger the wind, the more the water vapor loss
34. According to the passage, which of the following statement is TRUE?
A. The mineral elements will not be absorbed by the plant unless they are dissolved in its root.
B. The woody stems contain more water than the leaves.
C. Air existing around the leaf is found to be saturated.
D. Only part of the carbon dioxide in the plant is synthesized.
35. This passage is mainly about _____.
A. the functions of carbon dioxide and water
B. the role of water in a growing plant
C. the process of simple sugar formation
D. the synthesis of water with carbon dioxide

2020 年大学英语六级考试阅读冲刺模拟训练 (3) Scholars and students have always been great travelers. The official case for “academic mobility ” is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold. Mobility of this kind meant also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have no interest in being credited with a starling discovery, or a new technique. It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect. In the twentieth century, and particularly in the last 20 years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aeroplane, making contact between scholars even in the most distant places immediately feasible, and providing for the very rapid transmission of knowledge.
[外语类试卷]大学英语六级改革适用（阅读）模拟试卷22 Section B 0 Graying Population Stays in the Pink A)Elderly people are growing healthier, happier and more independent, say American scientists. The results of a 14-year study to be announced later this month reveal that the diseases associated with old age are afflicting fewer and fewer people and when they do strike, it is much later in life. B)In the last 14 years, the National Long-term Health Care Survey has gathered data on the health and lifestyles of more than 20,000 men and women over 65. Researchers, now analysing the results of data gathered in 1994, say arthritis, high blood pressure and circulation problems—the major medical complaints in this age group are troubling a smaller proportion every year. And the data confirms that the rate at which these diseases are declining continues to accelerate. Other diseases of old age— dementia, stroke, arteriosclerosis and emphysema—are also troubling fewer and fewer people. C)"It really raises the question of what should he considered normal ageing", says Kenneth Manton, a demographer from Duke University in North Carolina. He says the problems doctors accepted as normal in a 65-year-old in 1982 are often not appearing until people are 70 or 75. D)Clearly, certain diseases are beating a retreat in the face of medical advances. But there may be other contributing factors. Improvements in childhood nutrition in the first quarter of the twentieth century, for example, gave today's elderly people a better start in life than their predecessors. E)On the downside, the data also reveals failures in public health that have caused surges in some illnesses. An increase in some cancers and bronchitis may reflect changing smoking habits and poorer air quality, say the researchers. "These may be subtle influences", says Manton, "but our subjects have been exposed to worse and worse pollution for over 60 years. It' s not surprising we see some effect". F)One interesting correlation Manton uncovered is that better-educated people are likely to live longer. For example, 65-year-old women with fewer than eight years of schooling are expected, on average, to live to 82. Those who continued their education live an extra seven years. Although some of this can be attributed to a higher income, Manton believes it is mainly because educated people seek more medical attention. G)The survey also assessed how independent people over 65 were, and again found a striking trend. Almost 80% of those in the 1994 survey could complete everyday activities ranging from eating and dressing unaided to complex tasks such as cooking and managing their finances.
英语快速阅读：英语六级考试中的如何提高阅读效率在继“出国考托福需要的三种快速阅读（按住ctrl键，鼠标点击可做具体了解）技巧”和“出国考雅思需要快速阅读”等英语快速阅读文章外，精英特速读记忆训练网再推出“英语六级考试中的如何提高阅读效率”以供大家作英语快速阅读技巧及训练的参考。 大学英语六级考试大纲（2006年修订版）明确指出：快速阅读部分采用1~2篇较长篇幅的文章或多篇短文，总长度约为1200词。要求考生运用略读（skimming）和查读（scanning）的技能从篇章中获取信息。略读考核考生通过快速阅读获取文章主旨大意或中心思想的能力，阅读速度约为每分钟120词；查读考核学生利用各种提示，如数字、大写单词、段首或句首词等，快速查找特定信息的能力。 其中“每分钟120词”的“高速度”通常会让大多数考生感到无从下手。其实不必如此，下面介绍三招来实现快速阅读真正的又快又好！ 第一招：明确试题特点，做到有的放矢 从近几年的真题来看，快速阅读理解部分采用的题型有是非判断题、句子填空题和选择题等。 1. 是非判断题 是非判断题要求我们根据原文信息判断题目中各个句子的描述是“对（Yes）”、“错（No）”还是“未提及（Not Given）”。判断的原则是确定题干与原文语句之间的关系，基本标准是：如果题干与原文意思一致，就是“对（Y）”； 如果题干与原文意思不一致，就是“错（N）”； 如果题干与原文既不一致也不矛盾，则说明原文对题干表述的事物不曾提及，或未作判断，即为“未提及（NG）”。 2. 句子填空题 句子填空题主要通过改变原文句子结构，或者变换其中的连接词，或缺省其中的某个句子成分，让考生补充所需内容。这类题目要先分析所缺的部分，是一个词、短语、还是从句等，是名词性、动词性还是形容词性等，填的时候要“对症下药”；最后分析原文相关语句，尽量用原文词语填空，但要做到简练，以保证所填内容的准确性。 3. 选择题 选择题是快速阅读的一个备选题型，四个选项就意味着关键词出现的高频率，也相对降低了解题难度。快速阅读的选择题一般很少有需要推理或综合判断的题目，只需根据题干的关键词定位到文中相关语句，答案即一目了然。 第二招：掌握阅读方法，以求成竹在胸 快速阅读题目考查的阅读方法是略读（skimming）和查读（scanning），强调的是考生在实践语言环境中查询有效信息的能力，其中略读（skimming）的重点在于快速了解文章的中心思想，查读（scanning）的重点在于有目标地找出文中某些特定的信息。
距离大学英语六级考试还有不足一个月的时间，笔者给临战的考生朋友们一些建议。希望能通过本文帮大家梳理一个头绪，在最后的备战中尽量做到有的放矢，弹无虚发。 一、快速阅读。 大学六级中的第一道阅读题目是快速阅读，很多考生朋友都向笔者反映：快速阅读怎么做啊？拿到题目是先看文章还是先看题目啊？怎么我总是做不完题啊？有什么方法可以提高阅读速度啊？等等等等……这几个问题相信也是大家最关心的，那接下来，笔者将从六级快速阅读的命题特征，做题步骤，解题方法几个角度来谈谈如何攻克快速阅读。 1.六级快速阅读的命题特征。 六级快速阅读的文章篇幅约为1200单词，通常是略多一些的，整个题目的给定时间为15分钟。文章之后是十道题目，这十题可以会出现两种组合：一种为4道是非判断题(也就是大家所熟悉的Y/N/NG题)加上6道句子填空题(也可称补全句子)；另一种为7道选择题加上3道句子填空题。 至于考试最终会以哪种形式出题，在考纲中是没有明确说明的，从改革之后的几次实考情况来看，06年12月六级开始使用新题型，到09年6月的六级考试中，第一种题目组合形式考了两次，分别是06年12月和07年6月；第二种题目组合形式考了之后的四次。大家可以从以上的信息中来分配自己对于每种题型的复习时间。 2.六级快速阅读的做题步骤。 由于整个快速阅读部分总体时间为15分钟，如果不进行合理的规划，这样的时间是绝对不够用的。很多考生朋友会问到底应该以一种什么样的顺序来做题？我们先来了解一下在考试大纲中的说法： “要求考生运用略读和查读的技能从篇章中获取信息。略读考核学生通过快速阅读获取文章主旨大意或中心思想的能力，阅读速度约为每分钟120词。查读考核学生利用各种提示，如数字、大字单词、段首或句首词等，快速查找特定信息的能力。” 从考纲中我们发现，这里有三个重点信息：略读、查读、速度为120词/分钟。从这三点上我们基本上可以确实整体的步骤了，那就是选定信息+回到文章查找信息+对比解题。而且我们应该是看一题，做一题。这就是所谓的略读、查读。其实这正是我们平时所使用的从题干中找关键词，回文章定位的办法。快速阅读其实就是考定位。 而另外一个信息，阅读速度问题，表面上看到这个120词/分钟，很考生都望而却步，这绝对是一个无法企及的速度，但笔者提醒大家看它前面的文字，这样读的目的是为了获取文章主旨大意，而不是精细分析，于是结合大家以往所掌握的英语阅读知识应该知道，在英语中主旨的位置往往是相对固定的，想要把握1200个单词的文章的主旨根本不需要全文阅读，只需要看几个位置就可以了，如标题、首段、小标题。所以说这里的阅读速度应该更确切的讲是平均速度。

We live in a consumer society where there is an enormous demand for commercial products of all kinds. Moreover. an increase in industrial production is considered to be one solution to the problem of mass unemployment. Such an increase presumes an abundant and cheap energy supply. Many people believe that nuclear energy provides an inexhaustible and economical source of power and chat it is therefore essential for an industrially developing society. There are a number of other advantages in the use of nuclear energy.
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

1.Why Integrity Matters What Is Integrity? The key to integrity is consistency- not only setting high personal standards for oneself (honesty, responsibility, respect for others, fairness) but also living up to those standards each and every day. One who has integrity is bound by and follows moral and ethical (道德上的) standards even when making life's hard choices, choices which may be clouded by stress, pressure to succeed, or temptation. What happens if we lie, cheat, steal, or violate other ethical standards? We feel disappointed in ourselves and ashamed. But a lapse (缺失) of integrity also affects our relationships with others. Trust is essential in any important relationship, whether personal or professional. Who can trust someone who is dishonest or unfair? Thus integrity must be one of our most important goals. Risky Business We are each responsible for our own decisions, even if the decision, making process has been undermined by stress or peer pressure. The real test of character is whether we can learn from our mistake, by understanding why we acted as we did and then exploring ways to avoid similar problems in the future. Making ethical decisions is a critical part of avoiding future problems. We must learn to recognize risks, because if we can't see the risks we're taking, we can't make responsible choices. To identify risks, we need to know the rules and be aware of the facts. For example, one who doesn't know the rules a about plagiarism (剽窃) may accidentally use words or ideas without giving proper credit or one who fails to keep careful research notes may unintentionally fail to quote and cite sources as required. But the fact that such a violation is "unintentional" does not excuse the misconduct, Ignorance is not a defense. "But Everybody Does It" Most people who get in trouble do know the rules and facts but manage to fool themselves about the risks they're taking by using excuses: "Everyone else does it." "I'm not hurting anyone", or "I really need this grade." Excuses can get very elaborate: "I know I'm look at another's exam, even though I'm supposed to keep my eyes on my own paper, but that's not cheating because I’m just checking my answers, not copying." We must be honest about our actions and avoid excuses, if we fool ourselves into believing we're not doing anything wrong, we can't see the real choice we're making - and that leads to bad decisions. To avoid fooling yourself, watch out for excuses and try this test: Ask how you would feel if your actions were public and anyone could be watching over yore shoulder. If you'd rather hide your actions, that's an indication that you're taking a risk and rationalizing it to yourself. Evaluating Risks To decide whether a risk is worth taking, you must examine the consequences, in the future as well as right now, negative as well as positive, and to others as well as to yourself. Those who take risks they later regret usually focus on immolate benefits and simply haven't considered what might go wrong. The consequences of getting caught are serious and may include a "O" on a test or assignment, an "F" in the class, suspension (暂令停学) or dismissal from school and a ruined reputation. In fact, when you break a role or law, you lose control over your life and give others the power to impose punishment that you have no control over. This is an extremely vulnerable (脆弱的) position. There may be some matters of life and death or highest principle, which might justify such a risk, but there aren't many things that fall in this category. Getting Away with it - Or Not Those who don't get caught pay an even higher price. A cheater doesn't learn from the test, which deprives (剥夺) him her of an education. Cheating undermines confidence and independence: the cheater is a fraud, and knows that without dishonesty, he/she would have failed. Cheating destroys self-respect and integrity, leaving the cheater ashamed, guilty and afraid of getting caught. Worst of all, a cheater who doesn't get caught the first time usually cheats again, not only because he/she is farther behind, but also because it seems "easier." This slippery slope of eroding ethics and bigger risks leads only to disaster. Eventually, the cheater gets caught, and the later he/she gets caught, the worse the consequences. Cheating Hurts Other, Too Cheaters often feel invisible, as if their actions "don't count" and don't really hurt anyone. But individual choices have an intense cumulative (累积的) effect. Cheating can spread like a disease. Recent statistics suggest 30％or more of college students cheat. If a class is graded on a curve, cheating hurts others' grades. Even if there is no curve, cheating "poisons" the classroom, and others may feel pressured to join in. ("If I don't cheat I can't compete with those who do") Cheating also has a destructive impact on teachers. The real reward of goof teaching is seeing students learn. But a cheater says. "I'm not interested in what you're trying to teach, all I care about is stealing a grade, regardless of the effect on others." The end result is a destructive attack on the quality of your education. Finally, cheating can hurt the reputation of the university and harm those who worked hard for their degree.
2019 英语六级阅读模拟试题及答案（ 3 ）Passage One Questions 56 to 60 are based on the following passage. Caught in a squeeze between the health needs of aging populations on one hand and the financial crisis on the other, governments everywhere are looking for ways to slow the growth in health-care spending. Increasingly, they are looking to the generic-drugs ( 普通药物 ) industry as a savior. In November Japan's finance ministry issued a report complaining that the country's use of generics was less than a third of that in America or Britain. In the same month Canada's competition watchdog criticized the country's pharmacies for failing to pass on the savings made possible by the use of generic drugs. That greed, it reckoned, costs taxpayers nearly C$1 billion a year. Then on November 28th the European Commission issued the preliminary results of its year-long probe into drug giants in the European Union. The report reached a damning~, though provisional, conclusion：the drugs firms use a variety of unfair strategies to protect their expensive drugs by delaying the entry of cheaper generic opponents. Though this initial report does not carry the force of law (a final report is due early next year), it has caused much controversy. Neelie Kroes, the EU's competition commissioner, says she is ready to take legal action if the evidence allows. One strategy the investigators criticize is the use of the "patent duster( 专利群 )". A firm keen to defend its drug due to go off-patent may file dozens or hundreds of new
