标题: OG12 037 三点疑问
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
A中,第一个it是形式主语第二个是指代，含义不同。同一句中，同一代词可以起不同作用吗？
B中，OG说意思改变了。。。没看出来哪里不一样了。。。
C中，it指代schistosomiasis ，so...as to结构，schistosomiasis 也为become的动作发出者，没问题，哪里错了？
A是答案
谢谢~

首先，A中第一个it不是形式主语，就是指代的 schistosomiasis ，第二个也是的。表示它能使人变得很虚弱，所以成为了很多发展中国家财政支出的大头。也就是schistosomiasis is so debilitating that it has become an economic drain on many developing countries.
如果是形式主语的话，it is ....that是可以去掉而不影响句子意思的。在这里显然不是。

第二，B中economical表示经济的，节约的，节俭的，与economic意思不同。要说经济发展之类的用economic，说“买这辆车很经济很实惠之类的用economical。

第三点，我查了下manhattan老师的回答，他说这里不能用倒装，句子顺序很poor

首先，谢谢你的回答~
可能是我没说清楚，OG说的是B中debilitation改变了句子意思。economical属于另一个错误

第一点我明白啦
第三点，你的意思说只是不能倒装，而短语本身没有错是吧？最近见过好几个so...as to结构，对这个结构很迷茫。。

第二点中 it is so debilitating 是它能使（人）虚弱
而 it is of such debilitation 的意思是：它是如此虚弱
be+of+名词修饰某个词等于该名词的形容词形式修饰某个词
for example, "the flower is of such beauty" is equal to "the flower is very beautiful". in this case, "beautiful" modifies "flower".
that is to say, in the " it is of such debilitation " case, the quoted part means "it is debilitated", and "debilitated" is different from "debilitating", because the former one means "weak" while the latter one means "weakening" .

虽然OG 12 的解释说so...as to是一个错误的结构，但是我查了manhattan老师的帖子，他说在这题里主要是倒桩的问题，句子语序很poor，so....as to应该还是可以作为一个idiom。但是前提是绝对不能在逻辑主语的定位上引起歧义，结构要非常清晰。

我明白你的意思~但是，debilitation的形容词到底是debilited还是debilitating呢？我查了，后者也是。。。这里该如何选择。。。

作者: sandychen168 时间: 2011-8-17 23:58
be of加抽象名词表性质，而debilitation的意思是衰竭，不是使衰竭，所以of debilitation是它衰竭了的意思。
举个例子
it is of exhaustion 意思就是it is exhausted而不是it is exhausting

我的疑惑是E选项 so much deblitation结构正确吗
