托福听力地质类的文章内容比较多，难度也比较大，通常地质类的文章语速还比较快。为此，特别为大家总结了一下地质类题目的主要考点，一起来看看吧。

moving stone, dating ,glaciers, desert lake, geologic epoch,cave等

考核的方面主要有：

1. 某个理论的内容

content(scientist theorized that…

2.教授对某理论的态度，是赞成还是否定还是中立

attitude (geologist/people/profess think…. I am sure……most of us thought …. I will predict that…..)

3.这个理论如何得出的

4.这个理论或者现象如何普及的

5.这个理论或者现象的因果关系

Cause and effect (某一个现象)

There are a couple of the factors that affects……

6.某个地质现象的形成过程

例题：

举例一篇关于讲Kettle lakes 的文章

文章内容是这样的：

Uh, Other things that glaciers can do is ,uh, as they retreat, instead of deposting some till ,uh, scraped up soil, in the area, they might leave a big ice block and it breaks off and as the ice block melts it leaves it leaves a depression which can become a lake,. These are called kettle lakes. These are very critical ecosystems in this region, um because they support some unique biological diversity, these kettle lakes do.

The Great Lakes are like this, they were left over from the Pleist -from the Pleistocene glaciers , the Great Lakes used to be a lot bigger as the glaciers were retreating , some of the lakes were as much as a hundered feet higher in elevation. The beach of a former higher stage of Lake Erie was about fifty miles away from where the beach -the current beach of Lake Erie is right now. So I just wanted to tell you a litle bit more about glaciers and some positive things that we get from climate change. Like the ecosystems that develop in these kettle lakes, and how we can look at them in an enviromental perspective

题目如下：

一． What are kettle lakes?

A. Lakes that form in the center of a volcano

B. Lakes that have been damaged by the greenhouse effect

C. Lakes formed by unusually large amounts of precipitation

D. Lakes formed when pieces of glaciers melt

这个题目属于名词解释题，答案跟glaciers 有关系。原文说they might leave a big ice block and it breaks off and as the ice block melts it leaves it leaves a depression which can become a lake,. These are called kettle lakes.答案为Lakes formed when pieces of glaciers melt. 冰川这个词应该是托福学生都熟悉的，再起次就是Retreat 跟 melt 有同义替换。

二． How did the glaciers affect the Great Lakes?

A. they made the great lakes smaller

B. They made the greate lakes deeper

C. They reduced the biodiversity of the great lakes

D. They widened the beaches around the great lakes

原文提到Great lakes 这个专有名词时就要注意做好笔记，原文说The Great Lakes are like this, they were left over from the Pleist -from the Pleistocene glaciers , the Great Lakes used to be a lot bigger as the glaciers were retreating , some of the lakes were as much as a hundered feet higher in elevation.

Great Lakes like this　这句话是个提示词，其次就是used to be,这个词也很关键，听到这两个词，基本上定位就有了，根据文章: 过去Great lakes 比较大因为冰川溶解了所以海拔高了。海拔这个次托福学生必须要知道 elevation所以题目答案为they made the great lakes deeper.
