og 136, 谢谢

136. 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

答案A是标准的正确。 但我还是不明白C。 看过以前的贴子，说C改变了时态。而OG的解释是：C uses an awkward and wordy construction in place of a that... clause. 看OG的意思是不满意SO AS TO。用SO AS TO 的时候要前后逻辑主语一致， 还不能用在复杂结构中。C没有逻辑主语不一致的问题。是不是因为C用了到装句， 只能用SO THAT表达？如果不用到装，改成 it is so debilitating as to has become an economic 和语法吗？

谁帮我解释以下， 谢谢了。

renprince

it is so debilitating as to has become an economic 是没有问题的，我想
重要的还是所谓的时态变动的问题，所以无法选择c

I am confusing.to后面可以加has ? 应该用原型吧？

merlion

是呀是呀， 忘了， to 后应是 have。 只顾copy了。

我有异议，我认为so adj. as to v的结构中，to后面只能跟动词原形，不可能用完成时态(has become/have become都是完成时态呀)。也就是在这里so adj. as to的结构本身就是不妥当的，而不在于它的具体的形式。下面是我把所有阅读中（GMAT、GRE、LAST）中的so adj. as to结构一个不漏(还包括SUCH)的摘录，TO后面一律跟原形！
The first theory attributes a relatively constant population to periodic climatic catastrophes that decimate populations with such frequency as to prevent them from exceeding some particular limit.
Like other nineteenth-century Russian writers he is “impressive” because he “means what he says,” but he stands apart from all others and from most Western writers in his identity with life, which is so complete as to make us forget he is an artist. He is the center of his work, but his egocentricity is of a special kind.
(B) mesoscale phenomena are so large as to be easily detectable
One type of violation of the antitrust laws is the abuse of monopoly power. Monopoly power is the ability of a firm to raise its prices above the competitive level—that is, above the level that would exist naturally if several firms had to compete—without driving away so many customers as to make the price increase unprofitable.
This is why practitioners of law-and-literature end up discussing the law itself far less than one might suppose. Movement leader James White, for example, in his discussion of arguments in the Iliad, barely touches on law, and then so generally as to render himself vulnerable to Posner’s devastating remark that “any argument can be analogized to a legal dispute.”
Indeed, Temperley concedes that their “variety may be so great as to cast doubt on the notion of a ‘school.’”
(D) indicate that the idea of twentieth-century ecological reformers are often so theoretical as to be difficult to understand

GEMJ，强！！！GMAT都学到这儿份儿上了。

我的感觉对于so that和so... as to，GMAT明显倾向于用前者，除非在简单的助威结构中，尤其是在出现复杂的形式主语或者复杂的介词短语的时候，so that的确比其要清晰。至于时态的问题，今天又学到一招，不错。

谢谢，我跟安哥哥还有很多的高手相差太远。

有劳几位了， 谢谢

一点点想法
Conj. + S + V, S + V. 所以选A应该是最简洁明了了,
我觉得C没什么错,就是拐了个弯,不够坦荡.

so adj. as to v的结构中，to后面只能跟动词原形
