[讨论]so as to是必错吗？对比OG10与OG11解释

在OG11上面，好多题只要出现了so as to，官方就说so as to is not a correct idiom；而OG10，却有含有so as to的正确选项。

一直不明白，想是不是gmat现在转变了观点，认为so as to必错了呢？

例证：

OG11-33、OG10-136.

 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

OG10的解释：Choice A is best:C uses an awkward and wordy construction in place of a that... clause.

OG11的解释：C       The construction so x as toy is not a correct idiom

OG11-36、OG10-171

(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

OG10的解释：C lacks an appropriate conjunction, and the infinitive clause to be married to ... makes this choice awkward and unidiomatic.

OG11的解释：A So as to marry is not idiomatically correct; it does not identify who will marry

OG11-33、OG10-136.

 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

这个题先不说is it多余，so as to 表达的意思没有so that 准确，so as to 如此...以至于能... ,so.. that 表达的比较灵活，比如说这里的完成时只能用so that表示出来 用so as to意思变了，但并不是说出现 so as to 就错，而是用在这里不好

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

讨论这个的帖子也很热...  这里用so as to 同样有歧义，因为前面必须要有个动作发出，so as to 才能继续，比如我 execise, so as to become healtheir,

那么这个题是想说sought...so as to,还是have...annulled so as to, 呢？不清楚...因为他没表达清楚，原因是前面有两个动作，不知道到底是那个动作导致了 marry AB,这个体会一下

OG10-88. The Emperor Augustus, it appears, commissioned an idealized sculpture portrait, the features of which are so unrealistic as to constitute what one scholar calls an "artificial face."

(A)  so unrealistic as to constitute
(B)  so unrealistic they constituted
(C)  so unrealistic that they have constituted
(D)  unrealistic enough so that they constitute
(E)  unrealistic enough so as to constitute
至于这个题，so as to就是一个so that 得简化版本，没有任何歧义，用so that反而显得冗余。

非常感谢LS的回复，谢谢你详细的解释。

你的解释比较靠近OG10的解释，简单的说就是so as to在极少的情况下也成立。

但是OG11里，只要提到了so as to，他就说是错误的idiom。我认为OG11的意思是说在ETS的思维里，so as to已经变成了绝对错误了~~~~~

请问是不是这样呢？

so as to在判断的时候要分清楚 to后面的这个动作是不是逻辑主语的动作 so...that...就不一样 可以是不同主语

其实未必有OG10和OG11倾向谁 而是要看有没有逻辑主语的变动或者不妥引起的歧义 没有歧义就都是可以用的

众多的语法点都是殊途同归 句子的逻辑意思是否清楚而没有歧义
