　　10. 还有一个居然考了so as to!prep上有一个题讲解了so as to的用法 By Vivian0606

　　虎摸下狗主，这个本来就是个很重要的短语，还经常和so that一起拿来糊弄人

　　考点：so…as to…

　　so as to:

　　so as to连用的情况在GMAT里非常罕见，根据RON的原话翻译，“GMAC不太喜欢这个表达，正确选项从没见过”，“表示indirect intention”即非直接的目的

　　i.e. Joe bought a gym membership so as to become more attractive to women.

　　正确的常见的表达：So + ADJECTIVE + as to + VERB

　　使用事项：

　　1. 鉴于prep并未给出具体的so adj as to verb含义，我搜了一下RON的解释：

　　“in general, you don't use so ADJ as to VERB unless the VERB describes some sort of state/condition. i.e., if the verb is an action verb, this construction generally isn't used.”

　　RIGHT: i am so ugly as to be viscerally repulsive to women.

　　WRONG: i am so ugly as to repel women on sight.

　　第二句话错在“repel”是个动词上-应该为用”so…that”：

　　i am so ugly that i repel women on sight.

　　顺便吐槽一下写这句话的什么心态

　　总体来说， AS TO后面的VERB描述某种状态, 关于Ron说的最好不是动作名词，请注意一下“最好”，也可以是动作名词

　　比如： …demonstrably weak, it was not so weak as to require the recall of the automobile

　　(来自语法笔记)

　　2. prep给出的So…as to…与so…that的比较：

　　a. 主语连贯区别：

　　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。

　　练习题：来自prep2008语法笔记

　　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 (A)

　　E. gradual enough so that one cannot distinguish them

　　选项分析：

　　A. Correct. 主句为简单主系表结构

　　B. so...so that搭配错误(Incorrect Idiom)

　　C. able/unable to be done的结构错误

　　D. 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

　　E. enough so that错误搭配(Incorrect Idiom)

　　补充：关于so that/ such that用法

　　1. so that...

　　manhattan中关于so that...的用法举例：

　　RIGHT: She gave money SO THAT the school could offer scholarships. (= purpose)

　　SUSPECT: She gave money, SO the school was grateful. (= result)

　　WRONG: She gave money SO the school could offer scholarships.

　　下面看看Ron大神在manhattan论坛上的讲解：

　　-"so that..." the construction is placed in front of a clause that describes the intention or goal of some action. ("X ... so that Y..."就理解为Y是X这个action的intention or goal!)

　　e.g., James started weight training so that he could become stronger. (James的goal是become stronger, 他的action是started weight training.)

　　2. so... that...

　　manhattan中关于so... that...的用法举例(See also ENOUGH) ：

　　RIGHT: The book was SO SHORT THAT I could read it in one night.

　　The book was SHORT ENOUGH FOR me TO READ in one night.

　　Note: These two expressions have slightly different emphases, but it is unlikely that you will need to choose an answer solely on this basis. (第一句说是这本书很短，是不针对于哪个人的，但是后一句所这本书对于我来说很短，但是对于其他人不一定。微小区别，不作为split)

　　SUSPECT: The book was SO SHORT I could read it. (THAT is preferred.)

　　The book was OF SUCH SHORTNESS THAT I could read it.

　　The book had SO MUCH SHORTNESS THAT I could read it.

　　SUCH was the SHORTNESS of the book THAT I could read it.

　　WRONG: The book was OF SUCH SHORTNESS, I could read it. (run-on sentence)

　　The book was SHORT TO SUCH A DEGREE AS TO ALLOW me to read it.

　　下面看看Ron大神在manhattan论坛上的讲解：

　　-"so ADJ/ADV that ..." is used to emphasize the extreme quality of ADJ/ADV, and followed by some consequence of that extreme quality.

　　e.g.

　　Don is so tall that he can reach the top shelf without any effort. (Right)

　　I study so hard that I can get a good grade. (Wrong, 如果说get a good grade是study hard这么一个extreme quality的结果那就有点牵强了。如果能说明某个学科非常的难，过关率很低，然后我通过非常努力地学习取得一个好成绩，就可以说我”非常努力地学习“这个extreme quality的consequence是get a good grade.

　　3. such...that...

　　manhattan没有such...that...的list举例(可能在GMAT真题中出现很少或者就没出现过，这里当补充知识学习一下)

　　看看Ron大神在manhattan论坛上的讲解：

　　- "such + adj + noun + that", unlike "so adj that...", this one put emphasis not on an adj. We use this construction if the quality itself is embodied by a noun rather than by an adjective.

　　e.g. Tom is such a hermit that he hasn't left his house in two years. (Correct, hermit itself is a quality)

　　Don is such a tall boy that he can reach the top shelf without any effort. (Wrong, 这里换做用so... that...就会更好)
