1. Unlike a hurricane, which can be observed from within, a tornado is so small that such a study has not been practical.

(A) that such a study has not been practical

(B) that studying it that way has not been impractical

(C) for such studies as this to have been impractical

(D) as to not make such a study practical(A)

(E) as to be impractical of study

为什么不能选D呢?  so + n+as to do sth  不是也可以吗?

非nn, 个人观点

so...that,   so as to,,  so...as to 有好多讨论帖子.

一般so... that 正确,

金山词霸上解释:

so as to
adv.
使得, 以致
如此...以致于

so ...as to
这(那)样...以致

但是og11-33 , 对C 的分析中提到,  so x as to y is not a correct idiom

og11-36  提到 A 中so as to marry is not a idiomatically correct,  没有提出谁结婚.

以前的帖子,认为区分so as to 正确与否要根据时态 和 逻辑判断

此处, E, 有个错误, impractical 是 adj, 后直接加 study ,

应该是 an impractical study 吧? 不用of

G中没有so +adj+as to的

只有连着用

应该是吧, og11-33  C 中说so .. . as to...不是idiom
