[face=Georgia]1. Some people believe that witnessing violence in movies will discharge aggressive energy. Does watching someone else eat fill one’s own stomach?

In which one of the following does the reasoning most closely parallel that employed in the passage?

(A) Some people think appropriating supplies at work for their won personal use is morally wrong. Isn’t shoplifting morally wrong?

(B) Some people think nationalism is defensible. Hasn’t nationalism been the excuse for committing abominable crimes?

(C) Some people that boxing is fixed just because wrestling usually is. Are the two sports managed by the same sort of people?

(D) Some people think that economists can control inflation. Can meteorologists make the sun shine?

(E) Some people think workaholics are compensating for a lack of interpersonal skills. However, aren’t most doctors workaholics?

这个题目原文读懂了,但是提取什么信息导致原文选D呢?



11. “If the forest continues to disappear at its present pace, the koala will approach extinction,” said the biologist.

“So all that is needed to save the koala is to stop deforestation,” said the politician.

Which one of the following statements is consistent with the biologist’s claim but not with the politician’s claim?

(A) Deforestation continues and the koala becomes extinct.

(B) Deforestation is stopped and the koala becomes extinct.

(C) Reforestation begins and the koala survives.

(D) Deforestation is slowed and the koala survives.

(E) Deforestation is slowed and the koala approaches extinction.

这个题目答案是B,让我的确有些不明白.请解释一下B为什么正确?

没有问题啊. 从逻辑关系的角度分析:
Biologist: forest disappear (A)--> extinction (B)
Politician: stop deforestation (非A)--> no extinction (非B)
两个论题是不同的, 相当与互为否命题.
B对. stop deforestation, extinction. 按politician的逻辑是不可能发生的, 因为非A-->非B. 但biologist的逻辑依然可以成立. 当A-->B, 非A might or might not lead to 非B

这位大牛的解释我看了,但是我还是没有明白,请再次解释!



14. The “suicide wave” that followed the United States stock market crash of October 1929 is more legend than fact. Careful examination of the monthly figures on the causes of death in 1929 shows that the number of suicides in October and in November was comparatively low. In only three other months were the monthly figures lower. During the summer months, when the stock market was flourishing, the number of suicides was substantially higher.

Which one of the following, if true, would best challenge the conclusion of the passage?

(A) The suicide rate is influenced by many psychological, interpersonal, and societal factors during any given historical period.

(B) October and November have almost always had relatively high suicide rates, even during the 1920s and 1930s.

(C) The suicide rate in October and November of 1929 was considerably higher than the average for those months during several preceding and following years.

(D) During the years surrounding the stock market crash, suicide rates were typically lower at the beginning of any calendar year than toward the end of that year.

(E) Because of seasonal differences, the number of suicides in October and November of 1929 would not be expected to be the same as those for other months.

(1)这个题目的答案选C,我觉得C就是无关的.uring several preceding and following years怎么可以对1929年的高或产生影响呢?

(2)原文的"In only three other months were the monthly figures lower."是什么意思?[/face]

1，类比是两个逻辑上类似的东西的比较，不是自己和自己比较

其它的好象花梨鼠与mindfree两位讲过

再顶，贴海茫茫，我的确没有找到花梨鼠与mindfree的解答！请高手解答

ding,逻辑牛牛们来看看

1）类比的相似性。
14） 作者根据根据 1992 October， November 自杀率低，得出结论。
C说其实在1992 October， November 自杀率还是比前几年或者后几年高。也就是说有可能是这次1992 October 的stock market crash 产生的作用。也就是weaken这个推理

这个14题我还是没有搞懂，请再次讲解一下好吗？原文的结论是The “suicide wave” that followed the United States stock market crash of October 1929 is more legend than fact。C是如何削弱的呢？可以讲细一些吗？

ding,帮我看看14题，我还是没有搞懂

作者的结论是：The “suicide wave” that followed the United States stock market crash of October 1929 is more legend  than fact.也就是说The “suicide wave”  其实没有什么特别的是正常的。他的理由是：在那一年的October， November 的自杀率很低（从整体上作比较）。C的意思是说其实在1992 October， November 自杀率还是比前几年或者后几年的October， November 高（从相应10，11月来比较）。也就是提供一种解释：有可能是这次1992 October 的stock market crash 产生的作用，才使1992 October， November 自杀率还是比前几年或者后几年的October， November 高。
也就是说明了，The “suicide wave” that followed the United States stock market crash of October 1929 是有可能不正常的。

(1)这个题目的答案选C,我觉得C就是无关的.uring several preceding and following years怎么可以对1929年的高或产生影响呢?
答：原文提供的是横比，也就是在全年中10,11月份不高，但C项给的是竖比，讲在1929年，10,11两月的自杀率高于前后几年的（一般年份）的自杀率，反驳原文论据：1929年10,11月自然率不高，从而weaken原文的结论。


(2)原文的"In only three other months were the monthly figures lower."是什么意思?

答：这是一个倒装句，正装为the monthly figures were lower in only three other months.
说的是全年只有三个月的自杀率比10,11月份低，也就是说10,11月份的自杀率不高。
