在面对GMAT逻辑题目的时候,第一步就是看准问题,明确题目类型,从而运用不同的技巧解题。下面我们就对各种题型的关键词做一个总结,希望可以帮助你在考场上从容面对各种问题。
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。
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。
