我们都知道GMAT是一门偏重逻辑的考试，这个思想在各科里面都有体现，在阅读当中的推理题就非常需要大家能够运用逻辑思维来推理并解题，今天我们就带大家通过推理题常见的三种套路来带领大家充分的认知GAMT阅读当中的推理题
套路一：直接反推
规则：文章中提到了某件事情的情况是“1”，那么与这件事情对立的情况就是“-1”。
例文：
……
beyond that maximum, tunneling time stays the same regardless of barrier thickness. This would imply that once maximum tunneling time is reached, tunneling speed will increase without limit as barrier thickness increases.
……
题目：
The passage implies that if tunneling time reached no maximum in increasing with barrier thickness, then
A. tunneling speed would increase with barrier thickness
B. tunneling speed would decline with barrier thickness
C. tunneling speed would vary with barrier thickness
D. tunneling speed would not be expected to increase without limit
E. successful tunneling would occur even less frequently than it does
解析：
问题问当tunneling time没有达到最大值的情况，我们发现原文说的是达到了最大值得时候的情况是tunneling speed will increase without limit as barrier thickness increases，那么没有达到最大值的情况就是它的对立面，所以答案就是D. tunneling speed would not be expected to increase without limit
套路二：AB反推
规则：文章中提到了A和B两个相互对立的事物，且A的情况是“1”。问题让你推理B的情况，而文章对B的描述无法选择答案，那么答案极有可能需要用A来反推，也就可以根据A的情况推出B是“-1”。
例文：
……
The broader, classical definition is that a service is an intangible something that cannot be touched or stored. Yet electric utilities can store energy, and computer programmers save information electronically. Thus, the classical definition is hard to sustain.
The United States government’s definition is more practical
……
题目：
2. In comparing the United States government’s definition of services with the classical definition, the author suggests that the classical definition is
A. more pragmatic
B. more difficult to apply
C. less ambiguous
D. more widely used
E. more arbitrary
解析：
问题要推理researchers的观点，文中说了researchers认为pheromones是odorant（A推出了B），且文中给了一个事实是odorant等价于conscious（B等价于C）。所以我们可以得出答案A. pheromones are perceived consciously. （A推出了C）
希望对阅读当中推理题的讲解能够提升大家的逻辑思维，并帮大家做题阅读当中的推理题。
