单选题 To paraphrase 18th-century statesman Edmund Burke, "all that is needed for the triumph of a misguided cause is that good people do nothing". One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond force-fully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. 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 comes from or is tested in animals—no meat, no fur, no medicines. Asked if she 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 terms, 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.

单选题 The author begins his article with Edmund Burke"s words to

【正确答案】 A

【答案解析】[解析] 推断题。本题关键词为Edmund Burke"s words，通读全文发现篇首的话在篇尾得到了呼应：If good people do nothing, there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress. 一首一尾的呼应突出了这篇文章的中心：呼唤科学家们采取行动，切勿让人们的无知阻碍了医学的发展。所以应该选A项。B项错误的原因在于没有抓住文章的中心要义。C、D项无中生有。

单选题 Misled people tend to think that using an animal in research is

【正确答案】 B

【答案解析】[解析] 细节题。本题关键词为Misled people, using an animal in research。从前两段和第三段的最后一句中，可知受到误导的人们认为用动物做研究是残酷的、不可思议的。所以B项最符合原文。A项cruel(残忍的)正确，但是natural(自然的)不对，正相反，人们认为那是非常不合情理的。C项inevitable but vicious(不可避免的，但含有恶意的)也不正确。D项pointless and wasteful(毫无意义的，且浪费的)，实际上，人们的反对态度很强烈。D项虽无原则上的错误，但是不如B项更贴近原文意思。

单选题 The example of the grandmotherly woman is used to show the public"s

【正确答案】 B

【答案解析】[解析] 例证题。根据关键词grandmotherly woman、show the public"s定位至第二段。这个例子说的是一位老太太向大家散发传单，号召大家不要用任何来自于动物或在动物身上试验过的东西。当问及是否反对使用疫苗时，老太太并不知道疫苗是从动物研究中得来的。她认为，若疫苗也来源于动物，那么就不应使用疫苗，流行病自有科学家们用计算机来解决。可见老太太对科学的无知。而她的这种无知是很普遍的。第二段最后一句话感叹：Such well-meaning people just don"t understand. (这些好心人压根就不明白)。所以答案为B项。A项表述与主题不符，C项表述错误，D项无中生有。
