求大牛解答so as to的问题，谢谢。

OG12版P702 37题答案解释C项说 The construction so x as to y is not a correct idiom.

但是在GMAT网络课堂的语法课说，赵丽老师还说了so that 和 so as to 都有的时候选 so as to! 因为 so as to 更简洁！ 请问这是怎么回事啊？

askkoo老师说so as to是一个整体，不能用作so x as to y
so as to 是一个短语，so that 后要用从句。

但是赵丽老师的课堂是不是这么讲的。
她有用例句：Monkey King is so handsome as to be attractive. 显然按照赵丽老师的说法so x as to y 是可以用的。

如果以OG为准，是否以后我看见so...as to 的结构都可以判断是错呢？

额，没人解答么？

so as to be （这个结构出现过在官方材料：prep08的正确句子）

so as to be indistinguishable


so as to +working verb（没有出现过在GMAT的正确答案中）

so....as to 可用于简单主系表结构，to后面可接be动词，也可接实意动词。
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."

Climatic shifts are so gradual as to be indistinguishable at first from ordinary fluctuations in the weather.
都是正确的GMAT句型。

please refer to PREP 2008 GRAMMAR Notes (P18):
738.  The Emperor Augustus, it appears, commissioned an idealized sculptured 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
Key: A


If "so as to" cannot be followed by an action verb, why "constitute" is OK in this case?
And I am wondering why B and C are improper.
