求教39. 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
我根据economic和economical可以排除掉BDE, 剩下AC, 想问的是对于代词一般一句话中出现的单复数一致的代词代指的内容应该是一样的。那么A选项中第一个IT是指代that从句,第二个it指代的是 schistosomiasis 这不是明显不一致么?为什么还是对的呢?
好像不是吧,A选项的句型应该是so that 的结果状语从句,不是强调句,强调句把 it is ...that ...省略后还是一个完整的句子,可是这里省略后就变成了so debilitating it has become an economic drain on many developing countries.所以应该不是强调句。另外两个it 都是指代schistosomiasis的,个人见解,欢迎拍砖!
in general, you don't use so ADJ as to VERB unless the VERB describes some sort of state/condition. i.e., if the verb is an action verb, this construction generally isn't used.
for instance,
i am so ugly as to be viscerally repulsive to women. --> this works, because the verb “to be” describes a state/condition.
i am so ugly as to repel women on sight. --> you generally wouldn't see this in good writing, as “repel” is an action verb; the sentence would probably be written as i am so ugly that i repel women on sight.
