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

(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
