1、GMAT逻辑技巧——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?所以在解题的时候要格外小心。)
2、GMAT逻辑技巧——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)
3、第二种文章：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 forA; credit A to B.问题中的标志词：explanation; interpretation; hypothesis。
4、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。从题型上看，第一类文章的线索显然多于后两类，也就是说解题上较为方便，幸运的是第一类题目一般占去了考题的绝大部分，所以说还是有技巧可寻的。
