重问mindfree已经回答的两个逻辑!
[face=Georgia]6. Chronic fatigue syndrome is characterized by prolonged fatigue, muscular pain, and neurological problems. It is not know whether these symptoms are all caused by a single virus or whether each symptom is the result of a separate viral infection. A newly synthesized drug has been tested on those who suffer from chronic fatigue syndrome. Although the specific antiviral effects of this drug are unknown. It has lessened the severity of all of the symptoms of chronic fatigue syndrome. Thus there is evidence that chronic fatigue syndrome is, in fact, caused by one virus.
The argument assumes which one of following?
(A) All those who suffer from prolonged fatigue also suffer from neurological problems.
(B) It is more likely that the new drug counteracts one virus than that it counteracts several viruses.
(C) The symptoms of chronic fatigue syndrome are dissimilar to those of any other syndrome.
(D) Most syndromes that are characterized by related symptoms are each caused by a single viral infection.
(E) An antiviral medication that eliminates the most severe symptoms of chronic fatigue syndrome thereby cures chronic fatigue syndrome.
有是一个假设,我选的是C答案是B. mindfree的回答:2. B是正确答案. 原文的逻辑关系是:因为一种药可以缓解所有的症状, 所以这些症状是一种病毒造成的. 这里一种药和一种病毒就是assumption. 我不知道你选C的原因, 因为C是out of scope, 其它综合症的症状在此题中没有讨论
当时我排除了其他的答案留下了B/C.我并不认为C是无关的.C说 c的s和其他的s.是不同的,就是说那种药缓解的就是C的S,而不是其他的S,是和原文一致的。当时我的感觉是象排除他因。所以,就选C
请在解释一下?
Household indebtedness, which some theorists regard as causing recession, was high preceding the recent recession, but so was the value of assets owned by households. Admittedly, if most of the assets were owned by quite affluent households, and most of the debt was owed by low-income households, high household debt levels could have been the cause of the recession despite high asset values: low-income households might have decreased spending in order to pay off debts while the quite affluent ones might simply have failed to increase spending. But, in fact, quite affluent people must have owed most of the household debt, since money is not lent to those without assets. Therefore, the real cause must lie elsewhere. 11. Which one of the following, if true, casts the most doubt on the argument?
(A) Prior to the recent recession, middle-income households owed enough debt that they had begun to decrease spending.
(B) The total value of the economy’s household debt is exceeded by the total value of assets held by households.
(C) Low-income households somewhat decreased their spending during the recent recession.
(D) During a recession the affluent usually borrow money only in order to purchase assets.
(E) Household debt is the category of debt least likely to affect the economy.
这个题目大牛们给我解答的时候,我想问这样几个问题:(1)原文你读完后记下了什么?我总是读的很晕?(2)答案是A是如何削弱的。
mindfree的解释:. 读完原文应该对文中的逻辑关系和经济现象之间的关系有个认识. 原文提出造成recession的一个现象, 然后解释了为什么这个现象不是造成recession的原因,然后说应该是其它原因造成了recession. 这道题完全可以扩展为一到阅读题目, 原文的结构很典型, 指出现象, 提出一中解释, 然后否定这个解释, 提出是其它原因.
A是对的. 原文通过对low-income和affluent两种人进行了分析, 进而否定了indebtedness是原因, 但是漏掉了middle-income, 而A指出正是middle-income的indebtedness造成了decreased spending-->recession.
原文的结论是Therefore, the real cause must lie elsewhere,当时我的理解是A 是解释性的加强。正好是说明了原因所在。
请解释?[/face]
