托福阅读推理题技巧

托福阅读推理题技巧

托福阅读备考我们必须要掌握大量的词汇以及长难句的理解和一些背景材料，如果勤学习真题加上方法技巧，相信大家会有不错的收获。下面是我整理的托福阅读推理题解题技巧，供同学们参照!

一、推理题的标志

推理题的题干中一般含有infer, imply, most likely, least likely, probably等词，分为有共性的推理题和无共性的推理题两大类。

二、推理题的做法

关于无共性的推理题，也就是题干中无线索的，一般使用排除法，即依据各个选项的关键词回原文定位，通过排除法得出正确答案。

关于有共性的推理题，也就是题干中有线索的，建议考生可以先圈定题干中的关键词，依据关键词回原文定位，然后进行推理。推理题主要有以下思路：

1. 一般对比推理

ETS制定推理题的手段不多，依据两个事物的对比特征出题是

其中之一。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. 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. 时间对比推理

这种思路常被考到。在这种推理中，一般有两个形成对比的时

间段，它们所具有的特征一般相反。当题干问一个时间段的特征

时，只要将与之相反的时间段的特征否定掉就可以了。

例：

Basic to any understanding of Canada in the 20 years after the Second World War is the countrys 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

4新托福阅读背景知识分享

托福阅读中，影响大家阅读速度的，其实还是对文章的理解，关于一些专业性比较强或者偏门的文章，会大大影响我们的速度和做题的时间的。因此在备考的过程中，大家可以多了解一些相关的背景知识，供大家参照。

Lava

Lava is magma that breaks the surface and erupts from a volcano. If the magma is very fluid, it flows rapidly down the volcanos slopes. Lava that is stickier and less fluid moves slower. Lava flows that have a continuous, smooth, ropy, or billowy surface are called pahoehoe (pronounced path HOH eel hob eel) flows; while a (pronounced ah ah) flows

have a jagged surface composed of loose, irregularly shaped lava chunks. Once cooled, pahoehoe forms smooth rocks, while a a forms jagged rocks. The words pahoehoe and a are Hawaiian terms that describe the texture of the lava. Lava may also be described in terms of its composition and the type of rock it forms. Basalt, andesitic, decides, and hyalite is all different kinds of rock that form from lava. Each type of rock, and the lava from which it forms, contains a different amount of the compound silicon dioxide. Basaltic lava has the least amount of silicon dioxide, andesitic and deictic lava have medium levels of silicon dioxide, while holistic lava has the most.
