到底有没有so .. as to这种结构？是不是只有so as to？？？？

绝对有ＯＧ上有例子

我也很疑惑!!这里是og11-33的例子:

Although schistosomiasis is not often fatal,it is so delibitatiing that it has become an economic drain on many developing countries.

A.it is so delibitating that it has become an economic(right answer)

...

c.so deblibitating it is as to become an economic

答案对于c的分析:the construction "so x as to y"is not a correct idiom

划线考点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

The verbs are and calls indicate that the sculpture is being viewed and judged in the present. Thus, neither the past tense verb constituted (in B) nor the present perfect verb have constituted (in C) is correct; both suggest that the statue's features once constituted an artificial face but no longer do so. Also, B would be better if that were inserted after so unrealistic, although the omission of that is not ungrammatical. Choices D and E use unidiomatic construc­tions with enough: unrealistic enough to constitute would be idiomatic, but the use of enough is imprecise and awkward in this context. Choice A, which uses the clear, concise, and idiomatic construction so unrealistic as to constitute, is best

啊哦~~~找到反例啦!!!看来og也会强词夺理~~~~55555

4楼好厉害。

so..as to 应该是有的吧。

so + adj/adv + as to, do sth to the extent that one does sth

eg. She was so kind as to phone for a taxi for me.

How could you be so stupid as to believe him?

Would you be so good as to lock the door when you leave?

OG说the construction so x as to y is not a correct idiom是针对so..as to 这个结构吗？
