今天我在做OG 12第37题是注意到

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

Idiom

This sentence correctly uses the idiomatic construction so x thaty 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.

ACorrect. In this sentence, the pronoun
reference is clear, and the so x thaty
construction is concise.
C The construction so x as toy is not a correct
idiom.

The correct answer is A.

但是!
174. (28920-!-item-!-188;#058&003515)
Often major economic shifts are so gradual as to be indistinguishable at first from ordinary
fluctuations in the financial markets.
A. so gradual as to be indistinguishable
B. so gradual so that they can be indistinguishable
C. so gradual that they are unable to be distinguished
D. gradual enough not to be distinguishable
E. gradual enough so that one cannot distinguish them
却选的是A
有没有人能帮我解释一下到底能不能用
so...as to...  !!!thx!!

招招舟子

这题可拉倒吧，曼哈顿ron都说A和C都看不出错误...我们这水平就都别扯淡了

首先需要说明是：so that 和so as to是都存在的而且是idiom这点事没错的。但是so...as to的使用条件比起so  ...

C的逻辑主语怎么会是人呢？明明就是it 嘛，it 代之s-word

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
我也认为指代是一致的，但是C选项的倒装结构用错了，应该是so debilitating it is as to become an economic...
所以，so...as to在主语一致的时候优于so...that应该是一条通用规则。但是主语不一致的时候只能用so...that了

ainiAnnie

首先需要说明是：so that 和so as to是都存在的而且是idiom这点事没错的。但是so...as to的使用条件比起so that 更为严格。即so...as to...两个连接部分的逻辑主句一致才可以使用，一旦满足so...as to的使用条件，so...as to就优于so that 句式。否则so...as to只能是not idiom（说明逻辑主语不一致而不是so as to本身不存在）
接下来我们可以看到：
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
debilitating:a debilitating disease or condition makes your body or mind weak.使（身体或精神）虚弱。或使（组织机构）削减
C项中 debilitating的逻辑主句一定不是schistosomiasis(这个词我没有查到。。。）意思大概是是说，schistosomiasis虽然不致命，但是使人虚弱。逻辑主语是这个“人”而as to后面这个become 的逻辑主语很明显是schistosomiasis所以not a idiom.
so that 句式则表达的更为清楚。

174. (28920-!-item-!-188;#058&003515)
Often major economic shifts are so gradual as to be indistinguishable at first from ordinary
fluctuations in the financial markets.
A. so gradual as to be indistinguishable
B. so gradual so that they can be indistinguishable
C. so gradual that they are unable to be distinguished
D. gradual enough not to be distinguishable
E. gradual enough so that one cannot distinguish them

so 之后的gradual的逻辑主语为major economic shifts
as to之后的 be indistinguishable的逻辑主语为major economic shifts
二者一致。所以so as to不仅仅是idiom还是最优的结构，优于so that 句式（c选项)
而且，be able to do 是不能用被动的，can才可以用被动。（白勇语法）

以上个人意见，欢迎指正。

37题逻辑主语时一致的。debilitating 使...虚弱的，schistosomiasis 使人虚弱，主语均为 schistosomiasis.

lindasmile

自己也在纠结这道题，后来从manhattan上面看到的解释觉得挺对的:主要是so debilitating is it 的顺序不好，本身so...as to 这个短语可以使用。解释见下文

Saurabh, Here answer choice C is written: Although schistosomiasis is not often fatal, so debilitating is it as to become an economic drain on many developing countries. The OG explanation then says that so x as to y is not a correct idiom. However, in my view answer choice C could have been written correctly as: it is so debilitating as to become an economic drain on many developing countries. In my view, the GMAT recognized that this answer choice, as re-written above, would have been correct. Thus, it reordered the words in this answer choice to make this incorrect. In my opinion, the answer choice explanation is incorrect as to rule out the possibility of so X as to Y as an idiom, and this answer choice is wrong largely because of poor word order. I would not rule out an answer choice that uses this idiom, and regard is as an appropriate possibility. I hope that this is helpful. - Andrew

逻辑主语是一致的，就是schistosomiasis，怎么会有歧义？下面是OG上的解释：


This  is 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 modi?  ed by
the adjective debilitating.

白勇P246页38题中的E选项：these drugs caused such sever stomach disorders asto be banned by food and drug adminstration为什么不对呀？

白勇的说法是such/so...as to后边一般不加被动语态

比较这个正确的：Climatic shifts are so gradual asto be indistinguishable at first from ordinary... 大全214

yougushizi

这两个不确定，lzm上面说的：
1、so as to be还有点强调目的的意思
2、so +adj +as to be的前面需要有系动词或者be动词构成系表结构

首先需要说明是：so that 和so as to是都存在的而且是idiom这点事没错的。但是so...as to的使用条件比起so that 更为严格。即so...as to...两个连接部分的逻辑主句一致才可以使用，一旦满足so...as to的使用条件，so...as to就优于so that 句式。否则so...as to只能是not idiom（说明逻辑主语不一致而不是so as to本身不存在）
