如何在sat閱讀考試中提高速度，取得高分是每個考生都想了解的問題。今天小編為大家整理了關于SAT閱讀考試中長劍的結構性指示詞的資料，希望對大家把握文章結構有所幫助。
結構指示詞，即Direction Words，在SAT閱讀考試中的作用體現在三個方面：幫助預判focus或topic，幫助預判細節關系或者說是細節結構，幫助確定閱讀速度的快慢。來看下面的例子：
Reports on an organization’s 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 organization’s records.
上面文字中的several是一個不定數詞，它屬于Classification & Listing這一類Direction Words，當它出現在觀點句中或者結論句中的時候，它表明緊跟在它后面的名詞或者名詞短語就是下面文字的topic or focus，在這里我們知道下面文字的中心是報告的主要功能(major functions)。
其次通過several這一結構指示詞，我們還可以判定下面的細節部分不是分類討論結構就是列舉結構。最后我們既然已經能夠預判下文的中心和結構，也就自然能夠加快閱讀速度了，畢竟已知大意和目的的內容可以加快閱讀。
下面是六類SAT閱讀常見的結構指示詞：
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.
通過上面的介紹，我們就可以看到SAT閱讀結構性指示詞的內容和大家以前掌握的一些連接詞非常相似，但是范圍要更加廣一些。大家可以在備考SAT閱讀考試之前就對這些詞匯進行熟悉和記憶，在備考中經過一段時間的練習之后就會有更好的掌握了。
