SAT常见词汇复习 结构指示词

　　在今天的SAT常见词汇复习中，我们要给大家介绍的是结构指示词，即Direction Words。结构指示词在SAT词汇学习中的作用体现在三个方面：帮助我们预判focus或topic，帮助我们预判细节关系或者说是细节结构，帮助我们确定阅读速度的快慢。下面我们来进行SAT常见词汇结构指示词的复习，来看下面的例子：

　　Reports on an organizations projects may fill several major functions at the same time. A report can be used to educate and gain support from key people and groups, to facilitate and inform decision-making about current and future projects, and to provide documentation for the organizations records.

　　上面文字中的several是一个不定数词，它属于Classification Listing这一类Direction Words，当它出现在观点句中或者结论句中的时候，它表明紧跟在它后面的名词或者名词短语就是下面文字的topic or focus，在这里我们知道下面文字的中心是报告的主要功能。其次通过several这一结构指示词，我们还可以判定下面的细节部分不是分类讨论结构就是列举结构。最后我们既然已经能够预判下文的中心和结构，也就自然能够加快阅读速度了，毕竟已知大意和目的的内容可以加快阅读。

　　下面是六类SAT常见词汇结构指示词。
