说实在的，ＧＭＡＴ逻辑推理方法，真的不知道怎么使用，请进

以下题为例

19. How do the airlines expect to prevent commercial plane crashes? Studies have shown that pilot error contributes to two-thirds of all such crashes. To address this problem, the airlines have upgraded their training programs by increasing the hours of classroom instruction and emphasizing communication skills in the cockpit. But it is unrealistic to expect such measures to compensate for pilots’ lack of actual flying time. Therefore, the airlines should rethink their training approach to reducing commercial crashes.
Which one of the following is an assumption upon which the argument depends?
(A) Training programs can eliminate pilot errors.
(B) Commercial pilots routinely undergo additional training throughout their careers.
(C) The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.
(D) Lack of actual flying time is an important contributor to pilot error in commercial plane crashes.（D）
(E) Communication skills are not important to pilot training programs.

分清＂Ｂ，Ａ＂模式，不是＂Ａ，Ｂ＂模式真的那么重要吗？

读完题后，去掉了A,B,E三项．对C,D两项，有方法说只要加入NOT，看看段落推理是否仍成立，用这种方法C,D两项可以去掉一项，敢问not应该怎么加？各位高手，是按什么样的策略来解决这种题的？

顶．
逻辑的解决方法看来是不能拘泥于某一方面了

原文讨论的是：即使是培训，也不可替代   实际飞行时间

读了原文，应该想这实际飞行时间和飞行员出错有什么关系，而不是想怎么完善培训计划可以减少出错。

C说 靠培训来增加实际飞行时间可以降低坠机率。

其巧妙之处在于道理很对，但是把原文讨论的两个对象合并为一个了，所以不是原文在说的东西。

GMAT的CR题，在完全读懂题目意思后基本上就能直接选出来了。
真的吗？请问你曾经是进行CR的专项训练的？

书店里的有关GMAT的逻辑推理的书（作者陈向东）是否偏难了？厚厚的一本．它把Lsat,gre的推理都放进来了．

我担心的就是复习资料会误人子弟，是否我中招了．我

我没经过什么训练，目前就是做了OG12和PERP里的CR而已，

发现截止目前CR做错的原因基本都是阅读功底差没能读懂题意所致。

所以我想只要读懂，作对应该不是难事。

我觉得考场上比较紧张，1道CR也就1分半左右的时间，

有时候要彻底读懂题干和5个选择项的意思，就要1分多的时间了，

哪里还有时间让你去做什么推理分析呢。

所以我觉得复习CR还是要以提高快速阅读能力为主，并多做一些真题以熟悉出题人的套路。

当然，不排除有牛人在不需要完全看懂题意的情况下就能直接判断出正确答案的办法，

这个，我井底之蛙就不知道了

题目说：去年以来，整个电话机行业都卖的很好。为了利用这大好机遇，
MI公司计划扩大再生产，同时继续加大对广告的投入。
问：下面哪种情况，如果是真的话，最能否定MI公司的计划？
A：MI公司的市场份额下降了（那正好要扩大再生产啊！！）
B：MI的平均存货下降了（存货下降，这是好事啊）
C：广告使得MI的电话机家喻户晓，但没人知道MI有这个品牌(能卖得出就行了，谁管你消费者知道不知道是我生产的啊）
D：MI的电话机是去年增幅最大的3家之一（好事啊，刚好趁热打铁啊！）
E：MI的电话机销量下降了（整个行业都增长了，就你还下降了，那不正说明你的产品实在是太烂了，就别折腾啦）

38. Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth Industries (MI) plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.

Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above?

a) Although it sells all of the telephones that it produces, Mammoth Industries’ share of all telephone sales has declined over the last year.
b) MI’s average inventory of telephones awaiting shipment to retailers has declined slightly over the last year.
c) Advertising has made the brand name of MI’s telephones widely known, but few consumers know that MI owns this brand.
d) MI’s telephone is one of three brands of telephone that have together accounted for the bulk of the last year’s increase in sales.
e) Despite a slight decline in the retail price, sale of MI’s telephones have fallen in the last year

晕倒，看完以后，俺想不出除了e，您还能有什么其他选择。。。

俺看完就觉得D最像，呵呵。

别搞什么推理分析了，纯粹浪费时间。。。
