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词回原文精准定位，根据枚举法算出标准答案。
针对有共性的推理题，也就是题干中有案件线索的，环球教育海外考试研究所提议学生能够先选定题干中的关键词，依据关键词回原文精准定位，随后开展推理。推理题关键有以下思路：
1. 一般比照推理
ETS设计方案推理题的方式很少，依据2个事物的比照特征出卷是在其中之一。问在其中一个事物的特征时，要是将与之产生比照的另一个事物的特征否认掉就可以了。比如：
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.
Which of the following can be inferred from paragraph 1 about early sea otters?
A. It is not difficult to imagine what they looked like.
B. There were great numbers of them.
C. They lived in the sea only.
D. They did not leave many fossil remains.
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段，他们所具备的特征一般反过来。当题干问一个时间段的特征时，要是将与之反过来的时间段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.
