在知道如何解題之前，首先咱們得先知道什么樣的叫做推斷題，如果題目問(wèn)“ 從這段話可以推斷出什么”或者“根據(jù)某一段話下列哪一個(gè)描述是正確的”，類似于這種問(wèn)法的題目就是推斷題了，那么如何解這種題呢?我們一起看一道題：

　　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.(2005年 text 1)

　　25. What can we infer from the last paragraph?

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

　　[B] Human feelings of fairness 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.

　　解題的第一步，得先判斷題型，這道題其實(shí)就是比較典型的推斷題問(wèn)法，“根據(jù)某一段話下列哪個(gè)描述正確”。那么下面在解題之前，咱們先弄清楚這種題型的考察本質(zhì)，事實(shí)上段落推斷題其實(shí)考察的就是這段話的段落論點(diǎn)，那么問(wèn)題來(lái)了，段落論點(diǎn)去哪里找呢?根據(jù)學(xué)術(shù)性議論文的特點(diǎn)以及我們研發(fā)老師多年來(lái)對(duì)于題的研究發(fā)現(xiàn)，考研英語(yǔ)閱讀中的學(xué)術(shù)性議論文的段落論點(diǎn)往往在段中轉(zhuǎn)折，段首或者段末，所以我們解推斷題就重點(diǎn)看看那這三處，找到段落論點(diǎn)即可。

　　像咱們上面這道題，咱們找到的段落論點(diǎn)就是轉(zhuǎn)折however處，并且也是我們的段末句，所以很大可能它就是段落論點(diǎn)。下面咱們只需要拿著這個(gè)論點(diǎn)句去對(duì)比選項(xiàng)就可以了，不在定位句或者把幾句話中的細(xì)節(jié)信息拼湊雜糅的選項(xiàng)咱們可以直接排除，這道題我們就可以先排除CD，因?yàn)檫@兩個(gè)選項(xiàng)都是屬于信息的雜糅。那為什么A選項(xiàng)不排除呢，因?yàn)锳中的信息出現(xiàn)在了段首句，我們不能武斷地就認(rèn)為段末句就一定是論點(diǎn)，因?yàn)槎问拙湟彩怯锌赡艹蔀檎擖c(diǎn)句的。所以下面咱們仔細(xì)對(duì)比AB兩個(gè)選項(xiàng)就可以了，最后不管是對(duì)詞，還是對(duì)比意思，發(fā)現(xiàn)A與原文不符，屬于信息錯(cuò)誤，B才是更符合原文的。B選項(xiàng)中的Human feelings of fairness和原文論點(diǎn)句中a sense of fairness 同義替換，evolved原詞復(fù)現(xiàn)，an uncertain source和an unanswered question.同義替換，所以最終鎖定答案B。

　　因此，通過(guò)這道題，我們來(lái)總結(jié)一下推斷題的解題步驟，首先要先識(shí)別，然后找到段落論點(diǎn)，再去對(duì)比選項(xiàng)就可以了，在對(duì)比選項(xiàng)的過(guò)程中我們也可以把不在定位句或者信息雜糅的干擾項(xiàng)排除掉，以后見(jiàn)到這類題目大家就可以快速而準(zhǔn)確地解出來(lái)了。
