标题: [讨论]新PREP1-174

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

答案是A

C是不是错在了表达复杂？

因为A项的 so ... as to 不存在主语不一致的问题？

p.s想问一下，这个最新破解的语法题是从下面链接里的最新PREP软件里破解的么？

OG 11 SC94中的D选项中的 are be able to be trained同理错误，要被更简洁的can代替，修改为 can be trained。

A. so gradual as to be indistinguishable
Generally in Idiom "X...so ...as to be Y", Y refers to X, Which is true in this case. So its not ambiguous. I did not find any other problem so i moved forward.

B. so gradual so that they can be indistinguishable

So...so that.... : Incorrect Idiom : OUT

C. so gradual that they are unable to be distinguished

i found "be" is not required here, If it were 'so gradual that they are unable to distinguish", I would have choosen this, as it is more clear, But again Here it seems like economic shifts are doing some kind of action. Which is awkward.
editor: no. "they are unable to distinguish" is wrong for at least two MAJOR reasons.
first, it would mean that the economic shifts themselves are able to distinguish between things. this is clearly not the meaning of the sentence, nor is it at all reasonable.
second, you'd be left with just "distinguish from X", which is unidiomatic.

D. gradual enough not to be distinguishable
Correct idiom : enough..to.., usage is right here but "not to be distinguishable" is more wordy than indistinguishable. But still I will keep this in my pocket.
editor: i'm not sure whether "enough not to..." is idiomatic. see below.

E. gradual enough so that one cannot distinguish them
Incorrect Idiom : enough...to ?, so Out.

Out of A and D, I found A is more clear, using less Pronoun/Noun than D.
So I choose A.

真牛。。。要是每道题都这样说该多好啊

考点：
so …that V.S. so … as to be/do的用法：
    so … that可以用作多个主语时，so前面的主语和that后面的主语可以不一样；
    so … as to be/do一般用于单一主语，但是不能相隔太远，否则可以视为错误
原理：so … as to事实上是三个结构的结合，so引出的是状语，as指代句子前面的核心含义，to是不定式引导状语结构(adverbial structure)，此不定式修饰的正是前面的核心动词以及该动词的逻辑主语，所以只有当前面只有一个核心动词而且很明确的时候才能够用so…as to，也正因为修饰成分离被修饰词过远会造成修饰不清，所以to be/do结构不能与前面动词不能太远。
关于enough：
enough的固定搭配：
    enough for sb. 对某人来说足够了
    enough to do something  足够做某事
    错误搭配：(X) enough + ”that / so as to / so to / so that”。
(参考prep语法笔记2-94)enough to, so/such…that…, so/such…as to三者都表示结果,区别在于:enough to表示主观满足,在标准书面语中很少使用; so/such...that不用考虑逻辑主语问题; so/such...as to逻辑主语等于句子主语,即句子主语可以执行as to后面动词所表达的作用
选项分析：
Correct. 主句为简单主系表结构
so...so that搭配错误(Incorrect Idiom)
able/unable to be done的结构错误
enough偏向于主观判断，不符合逻辑语境；not to be distinguishable不如to be indistinguishable简洁
enough so that错误搭配(Incorrect Idiom)

able/unable to be done结构错误,既然是be able to...表示有能力，不能用被动？

able/unable to be done结构错误,既然是be able to...表示有能力，不能用被动？

嗯，其实这个从某个角度来看，是meaning的错误，而不是结构的错误

因为be able to 表示的是一种主动的能力
而被动表示的是非主动的能力
这显然是存在一种矛盾的，这是第一层次的meaning错误，也是general的

其次，第二层的meaning错误是本题的，也就是naturalwater所说的
这一句话中，distinguish的发出者是人，而非shifts，所以用be able to是错误的
