开始看GMAT大全上的逻辑了．时间不是问题，可总觉得选项的干扰怪怪的．好象不象LSAT看完后的答案很确定．请高手指点

9. Reva: Using extraneous incentives to get teenagers to change their attitude toward school and schoolwork won’t work. Take the program in West Virginia, for instance, where they tried to reduce their dropout rate by revoking the driving licenses of kids who left school. The program failed miserably.

R的观点： extraneous incentives 不管用。论据：west virginia 的program 就不成功。

Anne: It’s true that the West Virginia program failed, but many schools have devised incentive programs that have been very successful in improving attendance and reducing discipline problems.

A的反驳：virginia的program 是不成功。但是有很多成功的例子。A的暗示是，R的论据不具有代表性，不能说明问题。

According to Anne, the weak point in Reva’s claim is that it

(A) fails to consider the possibility that the majority of potential dropouts in West Virginia do not have driving licenses
(B) doesn’t provide any exact figures for the dropout rate in West Virginia before and during the program
(C) ignores a substantial body of evidence showing that parents and employers have been using extrinsic incentives with positive results for years

因为R根本没有提到除了该program 之外，父母和雇主使用外部激励的情况，而A也没提到这一点，故无干项。

(D) assumes that a positive incentive—a prize or a reward—will be no more effective than a negative incentive, like the revoking of a driving license（E）

这里也不是涉及到postive incentive 和negative incentive 的对比效果问题。因为A的反驳中举的例子并没有说明其他的成功的例子是采用negative incentive 还是postive incentive。故也是无干项。

(E) is based on a single example, the incentive program in West Virginia, which may not be typical

我居然2次都选了D．而且都是在D,E中比较的结果．不知道思维怎么出毛病了？？？？

LSAT跟GMAT思路其实有不小的区别。我其实不太同意做完LSAT再做GMAT逻辑会有居高临下的感觉。LSAT会sharpen your reasoning skill. 但是，对GMAT CR帮助并不如大多数人希望的那么大。打个比方，你居高临下时，你看到的景色其实是不一样的。你花了很多的力气搞明白的东西，大部分是GMAT中不作要求的。

LSAT更注重逻辑的严密性，而GMAT比较偏重理解方面和对细微点的把握。相对而言，你会觉得GMAT很含糊，难以把握。

时间紧的话，直接看GMAT. 其实OG很不错。但是我感觉很多人有点过于偏重LSAT对GMAT的作用了。

以上是我做完LSAT上下两册全部后，幡然省悟的心得。当然每个人的感悟不一样。

当然如果你考LSAT那就是另一回事了。
