标题: OG13 SC39 [打印本页] 作者: VINDAX 时间: 2016-6-17 15:54 标题: OG13 SC39 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
OG的解释是：
This sentence correctly uses the idiomatic construction so x that y where y is a subordinate clause that explains or describes x: So debilitating that it has become. ...It clearly refers to schistosomiasis, which is correctly modified by the adjective debilitating.
A Correct. In this sentence, the pronoun reference is clear, and the so x that y construction is concise.
B The noun debilitation creates an awkward, wordy alternative and a slight change in meaning; the subordinate clause is not introduced by that; economical does not have the same meaning as economic.
C The construction so x as to y is not a correct idiom.
D The construction introduced by such is awkward and wordy; ebilitation is also awkward and slightly different in meaning; that is omitted; economical does not have the same meaning as economic.
E The noun debilitation creates an awkward, wordy alternative and a slight change in meaning; economical does not have the same meaning as economic.
其他我都理解，但我觉得C项的 so as to 没有语法问题，Manhattan也说没有语法问题

so+adj.+that这是个标准用法，C的那个我完全没看出来哪里对了，整个读下来支离破碎的感觉，不知道为啥Manhattan说C没有语法问题作者: 请救非洲大象 时间: 2016-6-20 10:58
是这样的
这点我之前也纠结过：后来遇到一位大神的解释我豁然开朗～
在选择so that 与so as to的时候，
so... as to要求是比较高的：不仅要求这句话只有一个动词无歧义，还要满足当这句话改成 so...that 句型的时候，主从从句时态必须一致的。
c选项不能选主要就是因为第二条要求：so debilitating is it as to become an economic drain.
－－－－－－－so debilitating is it that it becomes an economic drain.
