一、归纳题

标志词：conclusion;inferred;implied;supported;if above true, then it is also true。(注：support不仅仅用于归纳法。举例来说，归纳法的表达应为：Which of the following are supported by the argument above?如果换个说法就可以变成加强题型的表述：Which of the following support the argument above?所以在GMAT逻辑解题的时候要格外小心。)

二、演绎题

1.第一种文章：前提推结论型

A.假设题：

标志词：assume;assumption;presuppose (特指对于前提的假设);additional premise;not true unless;depend on;rely on.

B.加强题：

标志词：support(注意和归纳题目的区分);strengthen, conclusion can be drawn if it were true that.

C.削弱题：

标志词：weaken;cast doubt;argue against;damage;counter;challenge;flaw;refute;jeopardize;criticism;undermine;drawback;reasoning error;weakness. (其中flaw，criticism，reasoning error和weakness属于名词性的削弱)。

D.评价题：

标志词：evaluate，appraisal(根据加强题做)

2.第二种GMAT考试文章：因果结构

文章内部标志词：A is due to B;A is attribute to B;A is result of B;blame B on/for A;B is responsible for

A;credit A to B.

问题中的标志词：explanation;interpretation;hypothesis.

3.第三种文章：“变态结构”(表面上仍然是前提推出结论的结构，实质为因果结构，即结论是前提的解释)。此类文章没有与众不同的标志词，需要考生在实战时分析判断，希望GMAT入门考生能掌握
