11. Scientific research at a certain university was supported in part by an annual grant from a major foundation. When the university' s physics department embarked on weapons-related research, the foundation, which has a purely humanitarian mission, threatened to cancel its grant. The university then promised that none of the foundation' s money would be used for the weapons research, whereupon the foundation withdrew its threat, concluding that the weapons research would not benefit from the foundation' s grants.

Which one of the following describes a flaw in the reasoning underlying the foundation's conclusion?

(A) It overlooks the possibility that the availability of the foundation's money for humanitarian uses will allow the university to redirect other funds from humanitarian uses to weapons research.

(B) It overlooks the possibility that the physics department' s weapons research is not he only one of the university's  research activities with other than purely humanitarian purposes.

(C) It overlooks the possibility that the university made its promise specifically in order to induce the foundation to withdraw its threat.

(D) It confuses the intention of not using a sum of money for a particular purpose with the intention of not using that sum of money at all.

(E) It assumes that if the means to achieve an objective are humanitarian in character, then the objective is also humanitarian in character.

答案:A,A不是与原文矛盾吗?这种题我做得经常错,不知有什么好办法?

17. Since the introduction of the Impanian National Health Scheme, Impanians (or their private insurance companies) have had to pay only for the more unusual and sophisticated medical procedures. When the scheme was introduced, it was hoped that private insurance to pay for these procedures would be available at modest cost, since the insurers would no longer be paying for the bulk of health care costs, as they had done previously. Paradoxically, however, the cost of private health insurance did not decrease but has instead increased dramatically in the years since the scheme抯 introduction.

Which one of the following, if true, does most to explain the apparently paradoxical outcome?

(A) The National Health scheme has greatly reduced the number of medical claims handled annually by Impania's  private insurers, enabling these firms to reduce overhead costs substantially.

(B) Before the National Health scheme was introduced, more than 80 percent of all Impanian medical costs were associated with procedures that are now covered by the scheme.

(C) Impanians who previously were unable to afford regular medical treatment now use the National Health scheme, but the number of Impanians with private health insurance has not increased.

(D) Impanians now buy private medical insurance only at times when they expect that they will need care of kinds not available in the National Health scheme.

(E) The proportion of total expenditures within Impania that is spent on health care has declined since the introduction of the National Health scheme.

答案

我选A,D怎么能解释这个现象呢?I 只在需要的时候买保险,并不能解释为什么个人费用并没有减少,而是大量地增加啊?

19,19. It takes 365.25 days for the Earth to make one complete revolution around the sun. Long ?standing convention makes a year 365 days long, with an extra day added every fourth year, and the year is divided into 52 seven-day weeks. But since 52 times 7 is only 364, anniversaries do not fall on the same day of the week each year. Many scheduling problems could be avoided if the last day of each year and an additional day every fourth year belonged to no week, so that January 1 would be a Sunday every year.

The proposal above, once put into effect, would be most likely to result in continued scheduling conflicts for which one of the following groups?

(A) people who have birthdays or other anniversaries on December 30 or 31

(B) employed people whose strict religious observances require that they refrain from working every seventh day

(C) school systems that require students to attend classes a specific number of days each year

(D) employed people who have three-day breaks from work when holidays are celebrated on Mondays or Fridays

(E) people who have to plan events several years before those events occur

答案:B,我选了E

谢谢.

11) 我觉得这种题最关键找出其推理过程。foundation 因为该部门保证不用foundation's money 在武器研究上就断定其不能从中受益（忽略了本来应该用在人道主义的钱被分配过来做研究，而把foundation's money 用到人道主义。也就是说还是可以受益的。其实很简单，钱都是有用的！哈哈）。
17）我觉得A首先可以排除。D只是提供一种解释，不能保证。D说Impanians要买National Health schemeScheme所不能提供的kinds。也就是把Health schemeScheme所不能提供的kinds都归于private insurance.范围扩大了，因此可以解释为什么private insurance显著增加。
19）E是个无关选项。只是说几年前做了计划在一个事件发生之前。首先固定时间应该排除。
B是说employed people 被限制在每隔7天做一件事情。假如从January 1 Sunday 开始，一年后应该是星期1（364+1）。但按照新的方法，又是Sunday，明显冲突（）。简单可以这样想。新的方法不是按7循环（7循环*52再做一个1天的调整），而B要求按7循环

买SCHEME 没有的保险，就能解释私人保险费用提高，而且得显著提高？

T11，你的解释是什么意思啊？

谢谢perfection。

17题E的意思是：买保险的人只有知道自己要得的重病的人才跟私人保险公司买保险。。而原来买保险的人不管有无病都买保险。。相比之下，私人保险的PROFIT肯定下降

天啊，第17题是这个意思，我终于明白了。谢谢albert!

大律师，请帮欧分析一下为什么D 对。 按照Albert 的说法，D的意思是：买保险的人只有知道自己要得的重病的人才跟私人保险公司买保险。。而原来买保险的人不管有无病都买保险。。相比之下，私人保险的PROFIT肯定下降

此选项怎可以这样翻译？或者说为什么 national scheme 提供的保险都是不痛不痒险，文中何处有暗示？谢！

原文意思为引进某个保险计划，该计划保险公司支付异常的医疗费，不像以前异常还是不异常都付。本来这样会使保险金（买某个保险的价格，这和利润挂钩）下降，但矛盾的是保险金反而增加。D提出解释说引入该计划后，人们只在有需要时才买保险。这样保险公司付医疗费的几率就增加，羊毛出在羊身上，这样保险金当然也随之上涨。

NATIONAL SCHEM提供的事普通医疗。西方国家有政府买单。但特殊的医疗费需个人买保险，因为医疗费贵得你付不起。

原来这里有个common sense... 藕真是没文化。

现在还有一个问题：选项D 中的主语Impanians 指什么？ 保险公司还是人？
