该题型可以说是细节题的升级版，难度也要高于一般的细节题，在每年的考研英语真题当中会出现2-4个，而且近两年还有增加的趋势，所以必须高度总是推断题的训练。通常，推断题的题干中会出现infer或suggest这种词眼，比如From paragraph four we can infer that ____. It is implied in paragraph 2 that the current immigration system in the US_______. 我们以2005年的真题为例：

　　The researchers suggest that capuchin monkeys, like humans, are guided by social emotions. In the wild, they are a cooperative, group-living species. Such cooperation is likely to be stable only when each animal feels it is not being cheated. Feelings of righteous indignation, it seems, are not the preserve of people alone. Refusing a lesser reward completely makes these feelings abundantly clear to other members of the group. However, whether such a sense of fairness evolved independently in capuchins and humans, or whether it stems from the common ancestor that the species had 35 million years ago, is, as yet, an unanswered question.

　　题干：What can we infer from the last paragraph?

　　[A] Monkeys can be trained to develop social emotions.

　　[B] Human indignation evolved from an uncertain source.

　　[C] Animals usually show their feelings openly as humans do.

　　[D] Cooperation among monkeys remains stable only in the wild.

　　解析：题干中出现infer属于典型的推断题。其中除了定位段落，没有给出具体的定位信息。所以此时我们应该先从定位段落出发，分析其中出现了哪些重点信息。段落当中的首句和转折句是重点信息的出处，因此可以优先匹配首句和转折句的意思，以节省时间。
首句The researchers suggest that capuchin monkeys, like humans, are guided by social emotions.讲猴子也受社会情感的引导，A选项的内容同样是讲情感，但是却说猴子可以被训练出情感，所以动词含义和原文不符，属于偷换概念。
然后我们读取转折句的意思However, whether such a sense of fairness evolved independently in capuchins and humans, or whether it stems from the common ancestor that the species had 35 million years ago, is, as yet, an unanswered question.这个种公平的感觉是在猴子和人身上独立的演化，还是源于共同的祖先，至今还是一个未解之谜。该句正好匹配[B] Human indignation evolved from an uncertain source.人类的愤怒情感来源是不确定的，符合原文信息。

　　推断题是考研英语阅读复习的重难点，需要考生多做真题，勤加练习，熟练掌握。
