想要搞定GRE阅读逻辑题，掌握方法很重要，好的方法能帮助你快速准确地解决题目，比如本文就会提到的三步解题法。今天小编就给大家介绍下GRE阅读逻辑题的三步解题技巧。

真题：

Exterminator: Using poisoned food is the most effective tactic for combating a mouse infestation. The mouse will carry the food back to the nest, causing all of the mice to die, while a trap will kill only the one mouse that falls into it. If all signs of the mice disappear for three consecutive weeks after poisoned food is used, the homeowner can be sure that the poison was successful in eradicating the mice.

Which of the following, if true, most seriously calls into question the exterminator’s claim that the absence of signs for three weeks means the mice have been eradicated by the poison?

(A) Because mice hide whenever they sense humans, it is very difficult to see or hear mice even when there is an active infestation.

(B) It is more humane to use live-catch traps that allow homeowners to release the still-living mice outside.

(C) In the spring, many mice that nest in houses begin foraging for food outside and do not return to the comfort of the house until the fall or winter.

(D) There are several different kinds of poison that could be used, some of which are more effective than others.

(E) It sometimes takes longer than three weeks for all of the mice to ingest and die from the poison.

想要快速解决逻辑题，有几个重要步骤必须做到。由于这些阅读题往往是短篇ARGU类文章的形式。所以通常都是某人想要总结某个观点，或者双方就一个观点进行争论的提问方式。

搞定阅读逻辑题第一步：确认问题类型

看文章前先看问题，问题会告诉你需要那种逻辑思维方式来解题，有时候还会包含文章的结论。而仔细阅读问题题干可能会帮助我们加强或者削弱结论、找出假设部分、进行推理、解决矛盾、分析文章结构。本题的问题，就是让我们去削弱结论。

搞定阅读逻辑题第二步：分解文章论点

一般文章的论点会由这几个部分组成。分别是：前提、结论、假设和反对前提。当阅读文章论点时，我们要学会分辨其中的这些部分，分解论点进行解析。

搞定阅读逻辑题第三步：排除答案选项

把答案的每个选项都检查一遍，首先，排除那些明显错误的选项，然后把剩下的选项进行对比。

选项A与结论的所有记号都消失矛盾，所以很明显是错误的，可以直接排除。

选项B没有谈到我们需要削弱的观点：3周没迹象=老鼠全被毒死了。所以排除。

选项C比较对路。假设正好这个计划在春季开展，有毒食物被放置好，而且3周没有老鼠的迹象，但也许并不是老鼠被消灭了，只是所有老鼠都正好离开了，靠着春季的充足野外食物生存，到了九十月份又会回来。这样就正好削弱了结论。所以这个答案比较正确。
