We asked the professor about the criteria by which he classifies the animal species.A:divides
B:categorizes
C:groups
D:defines答案：B解析：本句意思是：我们询问教授是以何标准给动物种群分类的。classi行意为 “分类，归类”，如：Men in the post office classify mnail according to places it is to go.邮局里的人员将信件按寄送地点分类。divide意为“分离”，如：Divide the cauliflower into fiorets and wash them thoroughly.把菜花拼成小块，然后仔细把它们洗干净。categorize意为“把······归类”，如： Categorize the plants into four groups.把这些植物分成四类。group作为动词意为“分组”，并不一定是一根据对象的某种特性而分组，如：The fact sheets are grouped into seven sections.这些资料被分成了七部分：define意为“给······下定义”，如：He was asked to define his concept of cool.他被要求说明自己关于“酷”的定义。只有选项B同句中画线单词含义接近。 -

Animal Testing Controversy
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 forcefully 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 animals一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一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 nee-- ded 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 re-search.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.The example of the grandmotherly woman is used to show the public's________
A:discontent with animal research
B:ignorance about medical science
C:indifference to epidemics
D:anxiety about animal rights答案：B解析：第一段中间提到“Scientists need to respond forcefully to animal rights advocates...”意思是科学家们需要采取行动回应这些动物权利的鼓吹者。这实际上就是一个呼吁，所以答案应该是A。
第一段最后一句说，被误导的人们“听到医学实验残忍对待动物的指控时，许多人都不明白为什么有人会故意伤害动物”。第二段举了被误导女士的例子，她反对用动物来做研究。第三段最后一句，这些人认为“动物实验说得好是浪费，说得不好是残忍”。A 内容不完整。inevitable：不可避免的；vicious：危险的，所以选项B正确。
该例子中，慈祥的妇人“encouraged readers not to use anything that comes from or is animals”，至于疫苗，如果来自动物她也抵制，认为流行病自有科学家们用计算机来解决。由此可见老人对科学的无知。第二段最后一句感叹“这些好心人根本就不明白”，所以答案为B。
根据关键词“challenge from animal rights advocates”以及“scientists should”, 可以在最后两段中找出作者向科学家们提出的建议都有助于他们与公众更好的交流。很明显选项A合理，选项B、C、D在文中没有提到，不正确。
最后一段“Finally,because the ultimate stakeholders are patients...Stephen Cooper, who has made courageous statements about the value of animal research”。从这句话我们知道，Cooper是个名人，也是患者，他曾经高度赞扬过动物研究的价值。由此可以推断他是支持动物研究的，正确答案是D。 -
