托福阅读推理题是托福阅读题型中稍有难度的题型，它需要大家在读懂文章的基础上看到一些文章内容“背后”的隐含义。也许大家会因此对自己失去信心。但是，不得不说，只要对这种题目有足够的认识，它并不难。接下来前程百利小编为大家带来托福阅读推理题出题点之一般对比推理的相关分析。
托福阅读题型中推理题的题干中一般含有infer, imply, most likely, least likely, probably等词，这是大家区分题型的依据。
ETS设计推理题的手段不多，一般对比推理就是根据两个事物的对比特征来出题。问其中一个事物的特征时，只要将与之形成对比的另一个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?
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.
根据关键词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两种动物与whales形成对比，而且很难想象原始的whales的样子;根据“一般对比推理”思路，可以推出“原始的 sea otters的样子不难想象”。第一个选项表达了此意，为正确答案。
以上就是前程百利小编带来的托福阅读推理题出题点之一般对比推理。大家只要明确了出题点，就知道该如何答题了。预祝大家托福考试取得好成绩!
