这些题型解题要点只提炼了一些比较实用的技巧，这些技巧简单来看并没有什么，但是在解题的过程中却能够体会到它们融入其中，，下面大家就通过两道例题体会一下吧。
一、GMAT逻辑加强题的解题步骤
1、看原文：找出结论和推出该结论的前提。特别注意结论的特殊性和具体性。
2、找答案：用结论的具体性去区分有关无关，并结合TEST。对于特殊类，先预测出答案，用此预测去找答案。
3、检正答案：问自己，选项是否在某方面帮助了作者。

二、GMAT逻辑加强题几种特殊类型
1、原文前提和结论关系不密切：正确选项直接支持结论。
2、因果型结论。
即原文给出两件事，然后得出结论说是一件事(因)导致另一件事(果)。SUPPORT该结论的方法包括：
A、没有其他原因或可能导致该结果。
B、结合因果：或有因有果或无果无因。
C、因果不颠倒了。
D、显示因果关系的资料是准确。
3、原文是类比：SUPPORT方式为两者本质相同。
4、调查：有效性不受怀疑(被调查的有代表性等)。
5、假设类支持。
将原文的推理中的GAP填补。消除原文的推理缺陷。因果型结论。条件型结论常以假设的形式出现。

三、GMAT逻辑取非例题分析
例一：
A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color. The inventor of the machine claims that it will reduce labor costs by virtually eliminating the need for manual weeding.
Which of the following is a consideration in favor of the company’s implementing its plan to develop the prototype?
A. There is a considerable degree of variation in shade of color between weeds of different species.
B. The shade of color of some plants tends to change appreciably over the course of their growing season.
C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds. (weakens)
D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.
E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.
1、正确答案：D。
2、例题分析：
situation: 通过differences in shade of color 来除草。
conclusion: 这种机器会减少人力成本，因为它最终减少了人为除草的需求。
support: 有方法能使各种作物有不同的颜色，而不改变其本身的属性。
其中B、C两选项者卢来weakens作用。A、E两选项与原文无关。
例二：
Capuchin monkeys often rub their bodies with a certain type of millipede. Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins. Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.
Which of the following, if true, provides the most support for the scientists’ hypothesis?
A. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it.
B. The two chemicals that repel mosquitoes also repel several other varieties of insects.
C. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak.
D. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub their bodies.
E. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins.
1、正确答案：C。
2、例题分析：
situation: 猴子常用m擦身子。
reason: m能分泌防蚊子的化学物质，而蚊子会传染猴子。
conclusion: 猴子常用m擦身子是为了防蚊子。
support: 在没有蚊子的季节， 猴子就很少用m擦身子。
