托福句子插入题是托福阅读中最容易出错的题型之一，今天长沙澳际教育的老师将给大家揭秘句子插入题的解题技巧，有了这些就再也不用担心插入题了!在线咨询

　　其实每个要被插入的句子都有提示信息供参考，分为以下几类：

　　1.指示代词：this, these their, it, such, another等(这些通常是上文提到过的，所以可以采用就近原则来做)

　　2.逻辑衔接词：therefore, so, however, as a result, consequently, on the contrary, however 等

　　3.递进扩展词：furthermore, also, as well, too, in addition, moreover, besides, even, additionally等;

　　4.结构配对词：on the one hand…. on the other hand，some…others

　　5.序数词：first ,second ,third等。

　　我们来具体来一个例子：

　　Above the tree line there is a zone that is generally called alpine tundra. █Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. █Some plants can even survive in favorable microhabitats above the snow line. The highest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. █At this great height, rocks, warmed by the sun, melt small snowdrifts. █

　　13. Look at the four squares [█] that indicate where the following sentence could be added to the passage.(4)

　　This explains how, for example, alpine cushion plants have been found growing at an altitude of 6,180 meters.

　　具体的解题步骤：

　　1. 理解要插入的句子

　　2. 寻找衔接词：这个句子的衔接词为This explain，这也就是说这个句子之前应该是理论或观点性的内容，再加上插入句中有6,180出现，说明是跟高度有关，所以可以排除A,B空，C和D只能选D，因为两个举例不会连着，而且举例之前需要有理论支撑，只有D符合。

　　3. 把句子代入并检查。

　　总之，理解需要插入句子的结构，找出衔接词和关键词是解答托福阅读题关键。同时要注意整个段落的结构以及上下文逻辑关系。
