Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal.For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that opposed immunizations; she wanted to know if vaccines come from animal research. When assured that they do, she replied, “Then I would have to say yes.” Asked what will happen when epidemics return, she said, “Don’t worry, scientists will find some way of using computers.” Such well-meaning people just don’t understand.Scientists must communicate their message to the public in a compassionate, understandable way-in human term, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother’s hip replacement, a father’s bypass operation a baby’s vaccinations, and even a pet’s shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst.Much can be done. Scientists could “adopt” middle School classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care.Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.1.

也就是说他们认为是可以避免的，用别的方法代替的，而并不是不可避免的，该选项属于反向干扰；D选项“毫无意义的和浪费的”，文中并没有提到毫无意义的是他们的看法，该选项属于曲解原文3. 【选项释义】The example of the grandmotherly woman is used to show the public’s ____. 这位老奶奶的例子被用来展示公众____A. discontent with animal research A. 对动物研究的不满B. ignorance about medical science B. 对医学的无知C. indifference to epidemics C. 对流行病漠不关心D. anxiety about animal rights D. 对动物权利的担忧【答案】B【考查点】事实细节题解题思路】根据题干信息可定位到第三段“当被问及传染病卷土重来时会发生什么时，她说：‘不要担心，科学家会找到使用计算机解决问题的方法’这些好心的人就是不明白由此可知用这个老年的例子说明他们对医学的无知因此选B干扰项排除】A选项“对动物研究的不满”，用该例子强调公众对医学的无知而不是对动物研究的不满，该选项属于曲解原文；C选项“对流行病漠不关心”，文中提到“当被问及传染病卷土重来时会发生什么时，她说：‘不要担心，科学家会找到使用计算机解决问题的方法。
’”可知这个老奶奶只是认为可以用计算机方法代替动物研究，而不是对流行病漠不关心，该选项属于过度推断；D选项“对动物权利的担忧”，文中没有体现，该选项属于无中生有4. 【选项释义】The author believes that, in face of the challenge from animal rights advocates, scientists should ____. 作者认为，面对来自动物权利倡导者的挑战，科学家应该____A. communicate more with the public A. 多与公众沟通B. employ hi-tech means in research B. 运用高科技手段进行研究C. feel no shame for their cause C. 不要为他们的事业感到羞耻D. strive to develop new cures D. 努力开发新的治疗方法【答案】A【考查点】推理判断题解题思路】根据题干信息可定位到第四段“科学家必须以一种富有同情心、易于理解的方式向公众传达他们的信息——用人性化的语言，而不是用分子生物学的语言以及倒数第二段“研究机构可以向游客开放，向他们展示实验室的动物得到了人道的照顾。
由此可推断，作者认为科学家应该多与公众沟通因此选A干扰项排除】B选项“运用高科技手段进行研究”，文中没有体现，该选项属于无中生有；C选项“不要为他们的事业感到羞耻”，文中没有体现，该选项属于无中生有；D选项“努力开发新的治疗方法”，文中没有提及，该选项属于无中生有5. 【选项释义】From the text we learn that Stephen Cooper is ____. 从课文中我们知道史蒂芬•库珀是____A. a well-known humanist A. 一个著名的人道主义者B. a medical practitioner B. 一个医疗从业人员C. an enthusiast in animal rights C. 一个动物权利的狂热者D. a supporter of animal research D. 一个动物研究的支持者【答案】D【考查点】事实细节题解题思路】根据题干信息可定位到最后一段“健康研究界不仅应该积极地招募史蒂芬•库珀这样的知名人士（他曾勇敢地声明动物研究的价值）”由此可知史蒂芬•库珀是动物研究的支持者因此选D干扰项排除】A选项“一个著名的人道主义者”，文中没有提及，该选项属于无中生有；B选项“一个医疗从业人员”，文中没有提及，该选项属于无中生有；C选项“一个动物权利的狂热者”，文中说到“健康研究界不仅应该积极地招募史蒂芬•库珀这样的知名人士（他曾勇敢地声明动物研究的价值）”可知他是动物研究的支持者而不是动物权利的狂热者，该选项与原文意思相反，该选项属于反向干扰。

How difficult is clarity of thought, and yet it is only as thought becomes clear that simplicity is possible. When we see a writer belaboring and idea we may be sure that the idea is belaboring him. This is proved by the general fact that the lectures of a young college assistant instructor, freshly graduated with high honors, are generally abstruse and involved, and the true simplicity of thought and ease of expression are to be found only in the words of the older professors.Simplicity presupposes digestion and also maturity: as we grow older, our thoughts become clearer, insignificant and perhaps false aspects of a question are cut off and cease to disturb us, ideas take on more definite shapes and long trains of thought gradually shape themselves into a convenient formula which suggests itself to us one fine morning, and we arrive at that true luminosity of knowledge which is called wisdom. There is no longer sense of effort, and truth becomes simple to understand because it becomes clear.【答案】简朴是思想深度的外在标志和象征。
在我看来，简朴是在学术和写作中最难做到的事情思想清晰是很难的，然而只有当思想变得清晰时，简朴才会实现当我们看到一个作家绞尽脑汁的时候，或许这个想法正在折磨他这一观点通常被如下事实所证明：一个刚毕业的高材生做了学校的助教，他写出的文章通常深奥难懂，而只有老教授才能有简明的思想和简易的表达简朴意味着领悟和成熟随着年龄的增长，我们的思想会变得更清晰，无用或者错误的东西将不会困扰我们思想更明确，而且经过长期的训练，我们的思想逐渐形成了它自己简明的模式，这暗示了思想清晰的开始届时，我们的思想达到了真正的高度，这就叫“智慧”于是，真理变得简单，而且理解不费力，因为它变得更清晰了17. 单选题If you cannot attend the meeting, please find someone to ____ for you.问题1选项A.replaceB.substituteC.displaceD.misplace【答案】B【解析】【选项释义】A. replace 取代 B. substitute 代替C. displace 取代；替代 D. misplace 随意搁置；乱放【答案】B【考查点】固定搭配。
解题思路】substitute for意为“代替；取代”由句意“如果你不能参加会议，请找人……你可知该搭配符合句意，意为“如果你不能参加会议，请找人代替你因此选A干扰项排除】A选项replace“取代”，replace for意为“将……取代成……”，不符合语境；C选项displace“取代；替代”，不与for搭配；D选项misplace“随意搁置；乱放”不符合语境句意】如果你不能参加会议，请找人代替你18. 单选题There are some earth phenomena you can count on, but the magnetic field, someday is not of them. It fluctuates in strength, drifts from its axis, and every few 100,000 years undergo, dramatic polarity reversal—a period when north pole becomes south pole and south pole becomes north pole. But how is the field generated, and why is it so unstable?Groundbreaking research by two French geophysicists promises to shed some light on the mystery. Using 80 meters of deep sea sediment (沉淀物) core, they have obtained measurements of magnetic-field intensity that span 11 polarity reversals and four million years. The analysis reveals that intensity appears to fluctuate with a clear, well-defined rhythm. Although the strength of the magnetic field varies irregularly during the short term, there seems to be an inevitable long term decline preceding each polarity reversal. When the poles flip—a process that takes several hundred thousand years—the magnetic field rapidly regains its strength and the cycle is repeated.The results have caused a stir among geophysicists. The magnetic field is thought to originate from molten (熔化的) iron in the outer core, 3,000 kilometers beneath the earth’s surface. By studying mineral grains found in material ranging from rocks to clay articles, previous researchers have already been able to identify reversals dating back 170 million years, including the most recent switch 730,000 years ago. How and why they occur, however, has been widely debated. Several theories link polarity flips to external disasters such as meteor impacts. But Peter Olson, a geophysicist at the Johns Hopkins University in Baltimore, says this is unlikely if the French researchers are right. In fact, Olson says intensity that predictably declines from one reversal to the next contradicts 90 percent of the models currently under study. If the results prove to be valid, geophysicists will have a new theory to guide them in their quest to understand the earth’s inner physics. It certainly points the direction for future research.1. Which of the following titles is most appropriate to the passage?2. The word “flip” (Para. 2) most probably means ____.3. What have the two French geophysicists discovered in their research?4. The French geophysicists’ study is different from currently prevailing theories in ____.5.
