　　GMAT考试有很多规律可循，如果能够找到其中的规律将会使备考达到事半功倍的效果，下面是本文为大家整理的GMAT逻辑套路，给大家参考。

　　GMAT逻辑套路，下面我们用两道削弱题让大家体会一下什么叫GMAT逻辑题的套路。

　　The ice on the front windshield of the car had formed when moisture condensed during the night. The ice melted quickly after the car was warmed up the next morning because the drosting vent, which blows only on the front windshield, was turned on full force.

　　Which of the following, if true, most seriously jeopardizes the validity of the explanation for the speed with which the ice melted?

　　A. The side windows had no ice condensation on them.

　　B. Even though no attempt was made to drost the back window, the ice there melted at the same rate as did the ice on the front windshield.

　　C. The speed at which ice on a window melts increases as the temperature of the air blown on the window increases.

　　D. The warm air from the drosting vent for the front windshield cools rapidly as it dissipates throughout the rest of the car.

　　E. The drosting vent operates ficiently even when the heater, which blows warm air toward the feet or faces of the driver and passengers, is on.

　　这道题的推理精华是“冰融化得快是因为空调开最大”，按照我们解题的套路是先判断它的假设，再进行反对。对于这一类典型的“现象解释型“文章，其假设的套路是“空调开最大是导致冰融化得快的唯一原因”，而我们要对此进行反对，当然是“空调开最大不是导致冰融化得快的唯一原因”或“还有其他原因导致冰融化得快”，我们可以把以上这句削弱的套路称为特征甲。当大家读完这道题的选项后会发现，没有与特征甲直接吻合的选项，但你会发现B选项其实表达的意思是一样的。

　　我们再来体会一下这一道题：

　　A conservation group in the United States is trying to change the long-standing image of bats as frightening creatures. The group contends that bats are feared and persecuted solely because they are shy animals that are active only at night.

　　Which of the following, if true, would cast the most serious doubt on the accuracy of the group’s contention?

　　A. Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roosting.

　　B. Bats are the chi consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humans.

　　C. Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South America.

　　D. Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted.

　　E. People know more about the behavior of other greatly feared animal species, such as lions, alligators, and snakes, than they do about the behavior of bats.

　　同样是一篇典型的“现象解释型”文章，其推理精华是“人们害怕并迫害蝙蝠仅仅因为它们是夜间活动的害羞动物”，而其假设的套路仍是“夜间活动的害羞动物是导致蝙蝠被人害怕并迫害的唯一原因”。现在我们做的是削弱，看看能不能找到“夜间活动的害羞动物不是导致蝙蝠被人害怕并迫害的唯一原因”这个选项呢? 乍一看上去没有完全吻合的，但仔细阅读和思考各个选项后你会发现，D选项讲的是不是也是一个道理呢?

　　上述就是有关GMAT逻辑套路归纳介绍，从上述的例子我们可以看到很多讨论都是换汤不换药，只要大家在平时多加练习相信是可以轻松突突破。最后预祝大家在GMAT考试中取得佳绩。
