首先看几道题 prep174. Often major economic shifts areso gradual as to be indistinguishableat first from ordinary fluctuations in the financial markets.
A.so gradual as to be indistinguishable B.so gradual so that they can be indistinguishable C.so gradual that they are unable to be distinguished D.gradual enough not to be distinguishable E.gradual enough so that one cannot distinguish them
答案选A 笔记的解释： so …that V.S. so … as to be/do的用法： so … that可以用作多个主语时，so前面的主语和that后面的主语可以不一样； so … as to be/do一般用于单一主语，但是不能相隔太远，否则可以视为错误 原理：so … as to事实上是三个结构的结合，so引出的是状语，as指代句子前面的核心含义，to是不定式引导状语结构(adverbial structure)，此不定式修饰的正是前面的核心动词以及该动词的逻辑主语，所以只有当前面只有一个核心动词而且很明确的时候才能够用so…as to，也正因为修饰成分离被修饰词过远会造成修饰不清，所以to be/do结构不能与前面动词不能太远。
再来看OG 37 37.Although schistosomiasis is not often fatal, it is so debilitating that it has become an economic drain on many developing countries.
(A)it is so debilitating that it has become an economic (B)it is of such debilitation, it has become an economical (C)so debilitating is it as to become an economic (D)such is its debilitation, it becomes an economical (E)there is so much debilitation that it has become an economical 答案选A，对于C的解释是so x as to y的用法是错误的
接着是og 39题 39.In 1527 King Henry VIII sought to have his marriage to Queen Catherine annulled so as to marry Anne Boleyn.
(A)so as to marry (B)and so could be married to (C)to be married to (D)so that he could marry (E)in order that he would marry
答案选D，答案中说so as to是idiomatically correct；没有指出who will marry
我的问题是，根据高中学的知识so...that和so...as to的意思是如此。。。以至于 so that 和 so as to是为了。。。 不知道这种说法在GMAT中是否适用 按照OG的理解是不是so。。。as to和 so as to都是错误的？ 但是prep上又说so。。。as to是正确的 我查了下manhattan，上面说so。。。as to在og第十版里是对的，在12版里就是错的了，他们也不知道为什么
到底so as to和 so。。。as to能不能选？？求大牛指导

我做这类题有两个个原则： 1.当so .... that.... 和so ....as to 都正确时优选so...as to....因为so as to 较so that来的简洁 2.那什么时候so as to不正确的呢？ 1）把so as to句型改成so that 句型如果主句和that引导的从句时态不一致则不能用so as to 改变 Although schistosomiasis is not often fatal, it is so一般现在时 debilitating that it has完成时 become an economic drain on many developing countries. (A)it is so debilitating that it has become an economic (B)it is of such debilitation, it has become an economical (C)so debilitating is it as to become an economic (D)such is its debilitation, it becomes an economical (E)there is so much debilitation that it has become an economical 2）so as to前面一定只能加单一的主谓结构，否则不能用so as to ,会引起歧义的 In 1527 King Henry VIII sought to have his marriage to Queen Catherine annulled 不是单一的主谓结构so as to marry Anne Boleyn.
(A)so as to marry (B)and so could be married to (C)to be married to (D)so that he could marry (E)in order that he would marry 运用这两个原则应该就不会错了的
你上面列举的37题解释C是so...as to 的用法错误，而不是这个结构本身错误不能用。如果用成it is so debilitating as to become an economic drain... 就是没问题的。

我当时也是根据多了个 is it来排除C选项的，但是在OG的解释中 明确说了so x as to y 是not a correct idiom，manhattan上说的是10版OG说so x as to y 是对的，但是12版说它又是错的了，所以很纠结，我就是想知道，如果考试真遇到了，只能通过so。。。that和so。。。as to来判断的时候算so x as to y错还是对
