一、推理題的標(biāo)志

推理題的題干中一般含有infer， imply， most likely， least likely， probably等詞，分為有共性的推理題和無共性的推理題兩大類。

二、推理題的做法

對于無共性的推理題，也就是題干中無線索的，一般使用排除法，即根據(jù)各個選項的關(guān)鍵詞回原文定位，通過排除法得出正確答案。

對于有共性的推理題，也就是題干中有線索的，可以先圈定題干中的關(guān)鍵詞，根據(jù)關(guān)鍵詞回原文定位，然后進(jìn)行推理。推理題主要有下列思路：

1.一般對比推理

ETS設(shè)計推理題的手段不多，根據(jù)兩個事物的對比特征出題是其中之一。問其中一個事物的特征時，只要將與之形成對比的另一個事物的特征否定掉就可以了。例如：

It should be obvious that cetaceans–whales， porpoises， and dolphins–are mammals. They breathe through lungs， not through gills， and give birth to live young. Their streamlined bodies， the absence of hind legs， and the presence of a fluke and blowhole cannot disguise their affinities with land-dwelling mammals. However， unlike the cases of sea otters and pinnipeds (seals， sea lions， and walruses whose limbs are functional both on land and at sea)， it is not easy to envision what the first whales looked like.

2. Which of the following can be inferred from paragraph 1 about early sea otters?

?It is not difficult to imagine what they looked like.

?There were great numbers of them.

?They lived in the sea only.

?They did not leave many fossil remains.

根據(jù)關(guān)鍵詞sea otters定位第四句：However， unlike the cases of sea otters and pinnipeds…，由原文的unlike可知sea otters和pinnipeds兩種動物與whales形成對比，而且很難想象原始的whales的樣子;根據(jù)“一般對比推理”思路， 可以推出“原始的sea otters的樣子不難想象”。第一個選項表達(dá)了此意，為正確答案。
