一、推理题的标示
推理题的题干中一般带有infer, imply, most likely, least likely, probably等词，分成有共性的推理题和无共性的推理题两类。
二、推理题的作法
针对无共性的推理题，也就是题干中无案件线索的，一般应用枚举法，即依据每个选择项的关键字回原文精准定位，根据枚举法得到标准答案。
针对有共性的推理题，也就是题干中有案件线索的，能够先选定题干中的关键字，依据关键字回原文精准定位，随后开展推理。推理题关键有下述思路：
1.一般比照推理
ETS设计方案推理题的方式很少，依据2个事情的比照特征出卷是在其中之一。问在其中一个事情的特征时，要是将与之产生比照的另一个事情的特征否认掉就可以了。比如：
It should be obvious that cetaceans�Cwhales, porpoises, and dolphins�Care 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.
依据关键字sea otters精准定位第四句：However, unlike the cases of sea otters and pinnipeds…，由原文的unlike得知sea otters和pinnipeds二种小动物与whales产生比照，并且难以想像初始的whales的模样;依据“一般比照推理”思路， 能够*“初始的sea otters的模样不难想象”。*个选择项表述了此意，为标准答案。
2.時间比照推理
这类思路常被考得。在这类推理中，一般有两个产生比照的时间范围，他们所具备的特征一般反过来。当题干问一个时间范围的特征时，要是将与之反过来的时间范围的特征否认掉就可以了。
例一：
Basic to any understanding of Canada in the 20 years after the Second World War is the country’s impressive population growth….
…It appeared that Canada was once more falling in step with the trend toward smaller families that had occurred all through the Western world since the time of the Industrial Revolution.
…
It can be inferred from the passage that before the Industrial Revolution
(A)families were larger.
(B)population statistics were unreliable.
(C)the population grew steadily.
(D)economic conditions were bad.
工业革命以后与工业革命以前2个時间产生比照。即然工业革命以后西方4的家中缩小了，那麼工业革命以前的家中一定较为大。因而(A)为标准答案。
