被彻底打击了。第二个test错了6个!!! 下面把我对第21题的分析贴出来: 21. Historian: We can learn about the medical history of individuals through chemical analysis of their hair. It is likely, for example, that Isaac Newton’s psychological problems were due to mercury poisoning; traces of mercury were found in his hair. Analysis is now being done on a lock of Beethoven’s hair. Although no convincing argument has shown that Beethoven ever had a venereal disease, some people hypothesize that venereal disease caused his deafness. Since mercury was commonly ingested in Beethoven’s time to treat venereal disease, if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct. Which one of the following is an assumption on which the historian’s argument depends? (A) None of the mercury introduced into the body can be eliminated. (所有身体摄入的水银都不能被抹去-太大了,与本论题无关) (B) Some people in Beethoven’s time did not ingest mercury. (在贝多芬时代有人不摄入水银)-这个是必须的,因为如果这个成立的话,那么人们均摄入水银,故不能证明贝多芬摄入水银与他有染性病有直接的关联!!) (C) Mercury is an effective treatment for venereal disease. (水银是治疗性病的有效手段,文中已经明确,不需再重提) (D) Mercury poisoning can cause deafness in people with venereal disease. (水银中毒可以导致感染性病的人耳聋,完全将几个不同的要素扯在一起) (E) Beethoven suffered from psychological problems of the same severity as Newton’s. (不相关) 逻辑推理过程: 历史学家认为,我们可以通过对人头发的化学分析来了解个人的医疗病史。比如说,很可能牛顿的心理疾病是由于水银中毒引起的。因为水银的微量元素在它的头发里面被找到。现在人们正在对贝多芬的头发进行分析。尽管现在还不能得出让人信服的结论说贝多芬曾经得过性病,但是有人假设说性病导致了贝多芬的耳聋。由于在贝多芬时代人们广泛地摄取水银用于治疗性病,所以如果可以在他的头发里面发现水银,那么我们可以得出以上的结论。 这段话的内容:1. 水银中毒导致了牛顿的心理疾病。2. 贝多芬是由于得性病而导致的耳聋(结论)。3. 贝多芬时代,如果患性病那么人们普遍使用水银进行治疗。4. 如果在贝多芬的头发里面发现水银,那么可以证明贝多芬患过性病。 这些点之间,需要一些论据来支撑。 |
