这种题，可能最好的方法还是集合法了吧，并且最好还是要用图哦，要不错了就很可惜了，因为这种题，花点时间，应该不会错的：）因为信息都很清楚了：P

谢谢zyh79的鼓励：））
两年前，上了趟薪东方，后来工作就忘了，现在我才检起gmat不久，然后听了那管大侃的录音。觉得还行，就琢磨着用了。
方法，还是交融一些吧：）我这还是头会上网和大家交流呢，多多包含：）

你说得很对，对信息的提炼对快速准确的解体至关重要，但这又要基于对文章，问题，悬项的准确理解（cr,rc）。并且对于rc，还不仅仅是读的问题，可能更重要的是记的问题，如果不能有连贯的简洁结构的记忆，我项细节定位很成问题。那可能有会涉及哪些内容该记，哪些内容不该记——载我们的记忆水平还不能全部记忆的情况下。所以“提炼”的另一层意思应该是“舍取”了。

对于cr莱是，我总觉得，选项中的状语从句并不重要，提炼方面可以忽略它。
也许我们在这里讨论问题可以用很多时间，但是真正考试的时候，就只能剩下最简洁的方法的，甚至方法都没有了，只剩下感觉——据说这是最高境界，但据一些大牛说，很多题也是按它自己的方法答了，对了也不知道为什么对的，错了也不知道为什么错的——载练习中，lsat逻辑有起给我这样的感觉（今晚菜做了2个section,远远落后你们了）。

我觉得，用适合自己的方法，按着简洁化原则，因为会有帮助的。

谢谢z_weining，以后只要是lsat，大家就一起上，把它搞定；
咳，连我自己都不知道为什么这么恨ets

test2-section2-19,

我觉得C如果改成否定,结论同样不成立: focus on increasing actual flying time=>crash will increase,  so the airline need not to rethink the training program,

如果这样考虑,E似乎也可以算assumption,
但光从意思上理解,C、E又是strengthen
到底应该怎样判断阿？？？ zyh79和各位高手能否帮忙看看！！谢谢

另外 第11题我觉得没有正确答案！ A is consistent with both biologist and politician， B is consistent with neither of them

test2-section2-19
   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.
(E) Communication skills are not important to pilot training programs.
这题我是这样理解的:
原文说：公司进行课堂训练，但不能弥补实际训练，所要重新考虑
但课堂训练是不是重要，文章没提，也许是两个都重要，缺一不可的情况，所以c,e不对。
当然，作为加强，C、E都可，不过加强与假设不同啊

test2-section2-11.
“If the forest continues to disappear at its present pace, the koala will approach extinction,” said the biologist.
“So all that is needed to save the koala is to stop deforestation,” said the politician.
Which one of the following statements is consistent with the biologist’s claim but not with the politician’s claim?

(A) Deforestation continues and the koala becomes extinct.
(B) Deforestation is stopped and the koala becomes extinct.
(C) Reforestation begins and the koala survives.
(D) Deforestation is slowed and the koala survives.
(E) Deforestation is slowed and the koala approaches extinction.
biologist：如果森林继续恶化，koala将消失
politivian：所以我们只需阻止森林恶化，就能防止koala消失
B:森林不恶化，koala消失
与biologist不矛盾：因为原文只说如果森林继续恶化，koala将消失
                   但没说如果森林不恶化，koala就不消失     

哦，对了，下次有可能的话，把原题也粘上来呀，可供大家看啊！

zyh79:  谢谢! 我下次一定贴原题!

11题我明白了,
第19题,我凭理解C、D、E的意思，觉得应该选D，但是如果用我题的那种“取非则结论不成立”就有点确定不了，不过想想也对，如果原来是strengthen的，取非后就有可能影响结论的成立，但我觉得这题的直接结论应该是such measures do not compensate for pilots’lack of actual flying time，而therefore 后的内容是间接结论。

感谢zyh79和我一起探讨！

Join this discussion:
19. Need a bridge: 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 . That is :

pilots’lack of actual flying time is one of the reasons of commercial crash.
==> D  correct?
11: zhy79 's explaination is good.
biologist：如果森林继续恶化，koala将消失 ( D--> E)
politivian：所以我们只需阻止森林恶化，就能防止koala消失( ~D --> ~E)
according to logical structure, we know there are different.
Question: Which one of the following statements is (consistent with the biologist’s claim but not with the politician’s claim?)
So: B:如果森林(delete继续)恶化stop ，koala(delete将)消失.Not comsistent with Politivian's claim.

决战金秋

楼上朋友，这种题请用数的集合论，最好解决。
ALL、NONE、NEVER等用大园表示，
MANY、SOME、等用小园表示（当然MANY要大一些）
但是偶也被此类题+双重否定等搞得头大，所幸GMAT不会考的

请教一道LSAT难题
9-IV-17.
Certain items—those with that hard-to-define quality called exclusivity—have the odd property, when they become available for sale, of selling rapidly even though they are extremely expensive. In fact, trying to sell such an item fast by asking too low a price is a serious error, since it calls into question the very thing---exclusivity---that is supposed to be the item’s chief appeal. Therefore, given that a price that will prove to be right is virtually impossible for the seller to gauge in advance, the seller should make sure that any error in the initial asking price is in the direction of setting the price too high.
The argument recommends a certain pricing strategy on the grounds that
(A) this strategy lacks a counterproductive feature of the rejected alternative
(B) this strategy has all of advantages of the rejected alternative, but fewer of its disadvantages
(C) experience has proven this strategy to be superior, even though the reasons for this superiority elude analysis
(D) this strategy does not rely on prospective buyers estimates of value
(E) the error associated with this strategy, unlike the error associated with the rejected alternative, is likely to go unnoticed
这题真得用难题猜A了
