Albert，恭喜！我还以为你考得不理想，730应该够申请牛校了吧？
你这个成绩对我们几个还未考的组员可是造成很大的压力啊！革命尚未成功，我们千万不能松懈的！
你考的AWA是哪两题呢？碰到的JJ多不多？比如阅读？
先好好休息一下！Good luck to you!

数学碰到了2-3到JJ，可惜都不是难题。。VERBAL我没看JJ，所以不知道。。
ISSUE：跨国公司让世界越来越同一化了。。
ARGUMENT：某城市建立一个SHOPPING MALL，产生了一系列后果。。所以是SHOPPING MALL导致的。。建议另一城市不要效仿。

请教两个削弱:

If the public library shared by the adjacent towns of Redville and Glenwood were relocated from the library’s current, overcrowded building in central Redville to a larger, available building in central Glenwood, the library would then be within walking distance of a larger number of library users. That is because there are  many more people living in central Glenwood than in central Redville, and people generally will walk to the library only if it is located close to their homes.
11. Which one of the following, if true, most seriously weakens the argument?
(A) Many more people who currently walk to the library live in central Redville than in central Glenwood.
(B) The number of people living in central Glenwood who would use the library if it were located there is  smaller than the number of people living in central Redville who currently use the library.
(C) The number of people using the public library would continue to increase steadily if the library were moved to Glenwood.
(D) Most of the people who currently either drive to the library or take public transportation to reach it would continue to do so if the library were moved to central Glenwood.
(E) Most of the people who currently walk to the library would remain library users if the library were relocated to central Glenwood.

我在A,B中拿不定,最后我选了A,答案:B]

The dean of computing must be respected by the academic staff and be competent to oversee the use of computers on campus. The only deans whom academics respect are those who hold doctoral degrees, and only someone who really knows about computers can competently oversee the use of computers on campus. Furthermore, the board of trustees has decided that the dean of computing must be selected from among this university’s staff. Therefore, the dean of computing must be a professor from this university’s computer science  department.
14. Which one of the following statements, if true, would weaken the argument?
(A) There are members of this university’s staff who hold doctoral degrees and who are not professors but who really know about computers.
(B) There are members of this university’s philosophy department who do not hold doctoral degrees but who really know about computers.
(C) Computer science professors who hold doctoral degrees but who are not members of this university’s staff have applied for the position of dean of computing.
(D) Several members of the board of trustees of this university do not hold doctoral degrees.
(E) Some members of the computer science department at this university are not respected by academics in莱坞other departments.

答案:A,我晕了.做了三分钟,没出来.
我的想法如下:
P: doctor degree+ computer+university staff, C: computer science+professor
A为何削弱啊?也不太行.如果A说:计算机系的教授不精通计算机,是削弱.

可是A说的是太泛,也是削弱吗?
谢谢.

1. A不是WEAKEN。
A说现在去图书馆的人中，住central Redville的人比住Glenwood 的人多。。和原文信息并不矛盾。。。原文比较的是：如果搬到Glenwood后，去图书馆的人会比现在去图书馆的人多多。。。注意：比较对象发生了改变。A是当前图书馆的两地方人比较。。原文是搬家前后总人数比较

2. 纯逻辑题目：
EVIDENCE:
1. dean 的必要条件： be respected, ability to over see ...
2. be respected 必要条件：doctoral degrees
3. ability to over see必要条件： really know computers
4. dean的必要条件补充： staff in this university
结论：the dean must be professor from this university's computer science department
看到结论，提出了一个DEAN的新必要条件：professor from .....
weaken方向：不一定需要结论的这个条件。。即举个反例子：不是professor from this computer science department 的人，但却满足前提给出的必要条件（其实也就3个：doctoral degree,really know computer and staff)

(A) There are members of this university’s staff who hold doctoral degrees and who are not professors but who really know about computers.
A满足了条件。。

(B) There are members of this university’s philosophy department who do not hold doctoral degrees but who really know about computers.
注意：选项应该是象这样子的： 某个满足前提必要条件的可不满足结论给出的条件。。
这里B，前提必要条件都不满足了。。看到do not hold doctor degrees，就排除掉了。

(C) Computer science professors who hold doctoral degrees but who are not members of this university’s staff have applied for the position of dean of computing.

C和B类似，看到not staff,排除。

(D) Several members of the board of trustees of this university do not hold doctoral degrees.
do not hold, 类似排除

(E) Some members of the computer science department at this university are not respected by academics in莱坞other departments.
not respected,类似排除。

所以，BCDE都是类似的错误。。明白了原文的关系，都是看一眼就可以排除掉的错误。。

关键：搞清楚差异。。。这里的差异在提了一系列必要条件后，结论却出了一个新的必要条件。。

JOYWZY, 第2题好象是从LSAT来的。。是个纯粹逻辑题目。。如果你时间不够，碰到这类题目可以不用做了。。

albert,第2题是LSAT的，可是削弱啊要，是GMAT要考的。

XDJM，帮我看看这几题吧，我的逻辑太差了。

LSAT－18－II

7. All psychiatrists are doctors. Only psychiatrists were invited to the conference. All who were invited to the conference stayed at the Hefford Hotel. Therefore, only psychiatrists stayed at the Hefford Hotel.

Which one of the following statements, if added as a premise to the argument, would make the conclusion valid?

(A) Only those who were invited to the conference stayed at the Hefford Hotel.

(B) All who were invited to the conference were psychiatrists.

(C) All psychiatrists were invited to the conference.

(D) No one who was invited to the conference failed to stay at the Hefford Hotel.

(E) Only doctors stayed at the Hefford Hotel.

答案：A，我选了D，好几个选项都可以啊。

这要是让mindfree知道了，非说我不可。

Questions 8-9

A thing is "nauseous" if it makes one sick to the stomach; the unfortunate victim of this malaise is "nauseated" . the common misuse of "nauseous" can be illustrated with the following sentence: "When he sits too long, turns his head too abruptly, or walks any distance, he gets dizzy, loses balance, and becomes nauseous." He doesn't become nauseous unless he turns other people's stomachs; he becomes nauseated. A person who is nauseated is no more nauseous than a person who has been poisoned is poisonous.

8. Based on the passage above, which phrase does NOT provide a logical completion to the following sentence? A person who is nauseated is no more nauseous than a person who has been_______.

(A) murdered is murderous

(B) corrupted is corruptible

(C) awed is awesome

(D) irritated is irritating

(E) scared is scary

答案：D，搞不明白。

10. Therapy, whether physical or social, is a counterirritant that aids in that equilibrium of the physical organs that protects the central nervous system. Whereas pleasure is a counterirritant (for example, sports, entertainment, and alcohol), comfort is the removal of irritants. Both pleasure and comfort are strategies of equilibrium for the central nervous system.

It can be concluded from the statements above that the exile of a deviant member of a group can be

(A) therapeutic for the rest of the group

(B) irritating for the rest of the group

(C) pleasurable for the rest of the group

(D) comforting for the rest of the group

(E) counter irritating for the rest of the group

答案：D，不明白怎么做的。

18. If there is a decrease in the number of homeless families, then either the number of available jobs has increased or else the cost of renting or purchasing housing has decreased. If the cost of renting or purchasing housing has decreased, then the supply of housing must be greater than the demand. Assume that there is a decrease in the number of homeless families.

According to the passage, which one of the following statements. CANNOT be true?

(A) The number of jobs has been decreasing.

(B) The cost of renting or purchasing housing has been decreasing, and housing has been decreasing, and housing supply exceeds demand.

(C) The number of jobs has been increasing, and the cost of renting or purchasing housing has been stable.

(D) The number of jobs has been decreasing, the cost of renting or purchasing housing has been decreasing, and housing demand exceeds supply.

(E) The number of jobs has been increasing, the cost of renting or purchasing housing has been increasing, and housing supply exceeds demand.

答案：D，我选了E，我觉得D和E都不对。

不好意思，太多了，谢谢。

谢谢Sunder, 我的思路一下子开了！

joy,
1、A排除了其他可能stay hotel的人，所以对；
2、前一个词表某人被怎么样了，后面的表示之后此人具有的特性；所以d;
3、pleasure-->counter irritants, comfort-->removal;
     题目说的是exile=removal, 所以d对；
4、题目说decrease of cost of renting house  or increase of jobs,因此2者相互排斥；
    所以d对，e前后矛盾：housing supply exceeds demand了，cost怎么会上升呢？

1. 结论讲的是酒店里只有某些人。。而EVIDENCE没有提到酒店是否只有某些人，只提到某些人去了酒店。。需要一个BRIDRAGE：去了酒店的人是唯一在酒店的人。
D我猜你选是因为否定词。。可是，D只讲了被邀请的人都去酒店。。而酒店是否只有这些人无从可知。
