37.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

关于这个问题一小点疑惑，B项OG解释的是debilitation的意思和愿意不同，是不是因为是名词不好的原因。

B中说的是这种病是debilitation（无力、乏力）。肯定不对塞
而应该是debilitating 使人乏力的

2楼说的，好像有点道理~

小可认为，应该关注最后一个词：economical和economic的区别，前者为经济的，节约的。后者为经济上的，或者是经济，这样B,D,E应该可以排除，A和C就不清楚了···求指导

C项： so …A…as to B 做了A，为了达到B。
肯定和愿意不符。

(C)so debilitating is it as to become an economic

这个读起来好别扭，而且找不到主语谓语啊。

先用economic和economical排除，然后是
B选项中, it is........我觉得首先可能是句子有两个谓语动词is，不对，然后是(个人认为)It is of such debilitation是倒装，such后应该加adj，请问lz正确答案是？

求A和C间怎么做选择

so … as to be/do一般用于单一主语，但是不能相隔太远，否则可以视为错误。而且不可以倒桩。
这里应该用强调句型，所以第一个it是形式主语，而后边那个it是schistosomiasis
