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。

Classification Listing category, classification, group, parts, types, characteristics, elements, kinds, sorts, ways, classes, features, numbers, 1,2,3,4, moreover, next, also, then, furthermore, etc. Sequence of Process first, now, later, second, after, stages, third, before, steps, next, finally, then, most, important, furthermore, when, last, etc. Example for example, for instance, to illustrate, such as, notably, to describe, specifically, perhaps the most, etc. Definition define, known as, we mean, is, that is, we can state, is defined as, the term means, etc. Cause Effect because, for this reason, since, cause, on account of, why, contribute to, due to, as a result, in effect, therefore, consequently, result in, thus, hence, the outcome is, accordingly Comparison Contrast compare, like/alike, resembles, likewise, similar, parallels, in comparison, in the same way/manner, although, however, on the other hand, as opposed to, but, instead, etc.

　　通过上面的例子和表格，我们对SAT常见词汇结构指示词进行了深入地学习。结构指示词是进行SAT语法学习的基础，也可以帮助理解阅读句子，希望引起大家的重视。
