GMAT考试中逻辑推理题所占比重较大,考查范围也早已超过英语语言本身,在平时与考生接触中,普遍的反映就是这部分题型比较难,在进行选择时往往顾此失彼,理不清头绪。我们给考生的建议是先去适应出题者思路,也就是我们不需要先拿着大量的题目去做,而要先看翻译好的题。其实对于逻辑推理题来说,总结出来的方法和步骤都是人为限定的,而我们的最终目的就是以自己的方法去快速地选对答案。
逻辑推理题本身并不难,但是在有限的时间内平静心情去解题并不是谁都能做到的。一般情况下,出题者会把正确答案局限在两个选项中,而其他的一般在读懂题目后比较容易排除,怎么样选出credited response就是我们要经过反复的比较和总结,对于那些ridiculously easy的题目,我们大可不必再看,而对于容易出错受迷惑的来说,就值得仔细斟酌一番了。
以下这个例题选自GMAT考生易错题之一,具有很高的借鉴价值,千万别错过哦~
A recent survey of all auto accident victims inDoleCountyfound that, of the severely injured drivers and front-seat passengers, 80 percent were not wearing seat belts at the time of their accidents. This indicates that, by wearing seat belts, drivers and front-seat passengers can greatly reduce their risk of being severely injured if they are in an auto accident.
The conclusion above is not properly drawn unless which of the following is true?
(A) Of all the drivers and front-seat passengers in the survey, more than 20 percent were wearing seat belts at the time of their accidents.
(B)Considerably more than 20 percent of drivers and front-seat passengers inDoleCountyalways wear seat belts when traveling by car.
(C) More drivers and front-seat passengers in the survey than rear-seat passengers were very severely injured.
(D) More than half of the drivers and front-seat passengers in the survey were not wearing seat belts at the time of their accidents.
(E) Most of the auto accidents reported to police inDoleCountydo not involve any serious injury.
这道题容易出错的原因在于distractors迷惑性大,中断思路,最后只能糊里糊涂地随便选一个完事,但恰恰就中了出题者的招。下面我们通过详细的解析来分析一下出题者的意图和相应对策。
大多数人没受重伤并没有说明是因为大多数人戴着安全带才伤得不重,E对观点支持并没起到作用。而D的半数概念并没有任何依据,注意这一类与题目无关的选项也是出题者比较喜欢设置的。A中说所有的被调查人中,多于20%的人都系了安全带,而严重受伤的人中只有20%系了安全带,这就说明系安全带所受的危险要小一些,对论断进行了支持。C说的前座与后坐相比重伤人员更多,对是否佩带安全带也无影响。B说的20%值得引起我们注意,可是他们在平时开车系安全带与坐飞机受伤其实也够不上什么关系,那么正确答案就是A了。
经过这样的分析以后,可能您觉得这道题并没有想象的那么难解。其实正因为逻辑推理题不涉及语言本身,所以它更具有客观性。解题的时候切忌模棱两可、凭感觉。对于绕弯较多的,一定要绕到底才行。
