掌握衔接词对解答这类问题非常重要，因为它是理解上下文和这个句子的逻辑关系的核心。

衔接词语主要包括代词(指示代词，例如this, these their, it, such, another ，这些通常是上文提到过的，所以可以采用就近原则来做。);关键同义词，重复出现的形容词，副词和名词;表示因果，转折等关系的过渡词语：如，therefore, so, however, as a result, consequently, on the contrary, however 等;递进扩展词：如，furthermore, also, as well, too, in addition, moreover, besides, even, additionally等;结构配对词：如，on the one hand…. on the other hand，some…others，同时还要注意一些表示顺序的词，如first ,second ,third等。

我们来具体来一个例子：

1. But there is also another special kind of conversational flow among Southern women that contributed to their writing. 2. Some of their talk took the form of tales and vignettes told for their own sake.3. Sometimes humorous, sometimes sad; all were as bright as the figures in the fine needlepoint. 4.

Look at the four positions that indicate where the following sentences can be added to the …paragraph of the passage.

These tales included grotesque, comic, and poetic descriptions, character sketches, narratives, gusts of feeling, delicate ironies, and astute observations.

Click on a position to add the sentence to the passage.

A: position 1 B: Position 2 C: Position 3 D: Position 4

具体的解题步骤：

1. 理解要插入的句子：These tales included grotesque, comic, and poetic descriptions, character sketches, and narratives, gusts of feeling, delicate ironies, and astute observations. 我们看这个句子是主、谓、宾结构，其中宾语为一些列的并列名词和短语。

2. 寻找衔接词：这个句子的衔接词为：These tales

3. 分析这个句子和上下文的关系：位置1 不可能，因为它后面的句子是一个主题型句子，即，提出论点，而我们要插入的句子为一个小点，属于论据。然后看位置2，这里出现了和我们要加入句子一样的信息点Some of their talk took the form of tales and vignettes told for their own sake。显然句子放在位置2是不行的;位置3后面的句子是对其前面句子for their own sake的进一步解释。所以最后只能是位置4了。

4. 把这个句带入各个位置。

5. 检查每个位置，位置4是最恰当的。

总之，把握这五大步骤是我们解决插入句子题的一个便利小窍门，具体的应用方法因人而议。理解需要插入句子的结构，找出衔接词是解题关键。同时要注意整个段落的结构以及上下文逻辑关系。

理解插入语在托福阅读考试中的作用是非常重要的，大家可以在备考的过程中根据自己的实际情况，从语法的角度入手，加入阅读方面的准备，这样才能更加容易的解答有关插入语的内容和题目。
