四、逻辑判断。每题给出一段陈述,这段陈述被假设是正确的,不容置疑的。要求你根据这段陈述,选择一个答案。注意:正确的答案应与所给的陈述相符合,不需要任何附加说明即可以从陈述中直接推出。
请开始答题:


研究人员分析了美国南加州将近4000名亚裔和非亚裔胃癌患者的病例资料,他们发现亚洲人的存活率远高于其他种族患者。一般而言,5年期的存活率,亚裔有20%的比例,拉丁裔是12%,而白人和黑人则是10%。一些研究人员推测,这可能是由于生物学上的差异导致亚裔人体内肿瘤较不具有侵害性。
下列哪项对这个观点不构成质疑( )

A.亚裔人的饮食习惯和其他种族不同,而饮食习惯对胃癌影响很大
B.亚裔人普遍重视体检,可以早期发现胃癌
C.亚裔肿瘤患者除接受西医治疗外,还常常接受中医疗法
D.亚裔人胃癌发病率比其他种族低

答案

参考答案:D

解析: 本题属于削弱论证题。题干所要削弱的观点是生物学上的差异导致亚裔人体内肿瘤较不具有侵害性,得出这一结论的前提是胃癌患者亚洲人的存活率远高于其他种族患者。选项A、B、C三项分别从“饮食习惯”、“体检”和“中医治疗”三方面进行他因削弱。选项D不存在削弱作用。所以选择D选项。

Animal testing

“It is always my ambition to be a research analyst studying amphibian anatomy(两栖动物解剖学 )for the benefit of mankind.” said Dr. Cull to the high school students touring the laboratory. “My ancestors were all scientists and my father taught   1  that it is simply amazing to appreciate the details in each creature. I also hope that my research can help us to understand   2  humans influences these creatures so that we can know how to improve   3 (environment) problems and correct our wrongs.”

“You are very ambitious, Dr. Cull.” a bright, amber-haired girl said. “So you are looking for similarities between animals and humans?”

“Yes, and there are already enough findings. We know much about how anesthetics(麻醉药) work, for example,   4 (base) on clinical trials with rats.” “But I disagree with using animals for tests!” another student suddenly said. “  5  is often discussed whether using animals for testing is moral. But the knowledge we have collected about health, vaccines, antibiotics   6 (be) incredible. We have benefited a lot  7   animal research.”replied the Doctor.

  8  I've seen videos of animals for research put in bad conditions.”Another student broke in.  “Oh, it seems that we've hit on   9  interesting topic.What about stepping into this conference room and discussing it   10 (far)?”
