SAT考试十分看重考生的SAT语法基础和使用能力的考察，有些语法点虽然简单，但如果考生没有将其“吃透”就很容易造成失分的现象。

　　以单词“so”为例，这个单词虽短，也很常见，但要真正掌握它的用法，还着实不易，因为它词意丰富，搭配众多，且词性诡异，在SAT语法考试部分，其出镜率很高，澳际上海学校VIP学习中心SAT团队的老师提醒各位考生千万不能小觑它，一定要掌握好每一个含义和搭配的用法，在考试中才不会被“陷阱” 迷惑。

　　一、“so”作为连词

　　1. 释义：for that reason;and therore

　　例句：There are no more chairs available, so you&aposll have to stand.

　　1. The problem of copyright violation, frequently compounded in certain countries because the sale and use of copyrighted materials are not tightly controlled. (OG：第八套题)

　　A. violation, frequently compounded in certain countries because

　　B. violation, frequently compounded in certain countries and

　　C. violation, frequently compounded in certain countries when

　　D. violation is frequently compounded in certain countries where

　　E. violation is frequently compounded in certain countries so

　　此题的考点是不完整句，谓语动词部分缺少了用于构成被动语态的助动词is，当答案范围圈定D和E时，就需要从where和so来下手了。通读题干，我们知道这里应该是因果关系，所以选择E。

　　2. 释义：used to say the reason for something

　　例句：Please be quiet so I can study.

　　此时也可以使用so that：I&aposll get a map so that we can plan where to go.

　　2. My mother always gave my sister and I (A) the same treats when we were little so that (B) neither of us would be (C) jealous of the other (D) . No error (E) (真题：09年10月)

　　此题的考点是代词的格，答案为A。在这道题目中，so that是一个从属连词，表示“以便”。

　　二、“so”作为副词

　　1. 释义：used when you are emphasizing a fact by saying what the result of it is

　　例句：She was so tired that she almost fell asleep at the dinner table.

　　这就是大名鼎鼎的so...that句型，在SAT语法考试中屡屡出现哦!

　　3. The new regulations have so complicated the process of formulating a school budget to where no one on the Board of Education is eager to undertake the task. (真题：06年10月)

　　A. budget to where

　　B. budget, therore

　　C. budget, even

　　D. budget as

　　E. budget that

　　此题答案为E，so...that表达了正确的语义逻辑。

　　2. 释义：and so=and therore

　　例句：Madeira has an ideal climate, and so it is not surprising that it has become a tourist paradise.

　　有的同学只知道so是连词，因此看到and so的时候，会觉得是两个连词一起使用，任务是错误用法。其实在and so这个搭配中，and是连词，so是副词。请看题：

　　4. Fabric was very expensive in the United States bore the Industrial Revolution, this is why scraps were saved and recycled into such items as patchwork quilts and doll clothes. (真题：09年1月)

　　A. Revolution, this is why

　　B. Revolution, this explains why

　　C. Revolution, and so

　　D. Revolution and so that

　　E. Revolution; resulting in

　　此题答案为C，and so改正了原文连写句的错误。

　　3. so...as to：used when you are emphasizing a fact by saying what the result of it is

　　这个结构也表示“如此...以至于”，只不过后面要加动词原形。请看题：

　　5. Cuban music was so popular in (A) the Colombian city of Cali thus becoming (B) the basis for (C) the dance scene that predominated (D) there during the 1940s. No error (E) (真题：10年1月)

　　此题答案为B，应该为as to become，以与前面的so构成搭配。

　　4. 同级比较的否定结构中：not so...as

　　大家都知道，as...as...表示是同级比较的肯定形式，在否定句中，前一个as可以换成so，这一点在SAT语法考试中也经常考察。请看题：

　　6. The director valued the actor not so much for his broad commercial appeal but because he approached every role with passion and intelligence. (真题：08年5月)

　　(A) but because he approached every role with passion and intelligence

　　(B) but because of his approaching every role with passion and intelligence

　　(D) but for being passionate and intelligent in approaching every role

　　(D) as for him approaching every role passionately and intelligently

　　(E) as for his passionate and intelligent approach to every role

　　此题答案为E，as与句中的not so构成比较结构，as后的for与not so后面的for构成平行。

　　5. (just) as ... so ...：formal used to compare two people or things, when they are similar

　　例句：Just as the French love their wine, so the English love their beer.

　　这个结构在SAT语法考试中出现了多次，如下面这道题：

　　7. Just as Ireland has produced many famous writers and the Netherlands on abundance of famous painters, so Finland has provided a large number of famous architects. (OG：第七套题)

　　(A) so Finland has provided a large number of famous architects

　　(B) Finland provides famous architects, and by large numbers

　　(C) Finland’s contribution is to provided famous architects in a large number

　　(D) and so then, for Finland, a large number of famous architects is provided

　　(E) and like them Finland has provided a large number of famous architects

　　此题答案为A。很多人以为just as是一个连词，so也是连词，不能在一起使用，其实是可以的。

　　2016年SAT考试将实行全面改革，改革后整体更为友好，减少对艰涩单词的直接考查，更为贴近学生的实际生活，但题目对于学生综合能力的要求更高。
