2. For the past 13 years, high school guidance counselors nationwide have implemented an aggressive program to convince high school students to select careers requiring college degrees. The government reported that the percentage of last year’s high school graduates who went on to college was 15 percent greater than the percentage of those who graduated 10 years ago and did so. The counselors concluded from this report that the program had been successful.

The guidance counselors’ reasoning depends on which one of the following assumptions about high school graduates?

(A) The number of graduates who went on to college remained constant each year during the 10-year period.

(B) Any college courses that the graduates take will improve their career prospects.

(C) Some of the graduates who went on to college never received guidance from a high school counselor.

(D) There has been a decrease in the number of graduates who go on to college without career plans.

(E) Many of last year’s graduates who went on to college did so in order to prepare for careers requiring college degrees.

这个题目a/e我没有分清楚，答案是E.

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.

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。

1，只就AE吧。A说10年来上大学的人数没变，结合文章，这个表述不能说明任何问题，比如毕业的人数增加，上大学的人数没变，说明比例减少了呢。E是说去年许多上大学的人正是为了给将来的职业打基础。而文中的gap(MINDFREE 偶剽窃你的说法了)就存在于，上大学的人数和选择需要大学学历的职业之间的关系，既然许多人是为了职业选择了大学，说明校方的方法有效。

1. 同意canberry的意见. 原文将上大学比例的增加归功于这个program. E就是将这两个现象联系起来.举个例子:有个program教育人们多吃菜,少吃肉, 因为吃肉不能去西方极了世界. 在实施了这个program后, 吃肉的人少了, 所以说这个program是成功的. assumption就是:那些改不吃肉的人是为了去XFJLSJ. 其它答案也可以是:肉都是疯牛疯猪; 吃肉的chlesterol高, 一个program教育人们不要吃肉以降低C, 避免心脏病; 等等

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.

3. 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.

3,我读到middle-income就认为是新概念，把这个选项扔了，考试时碰到这种情况可就惨了。
