Technically,“quicksand” is the term for sand that is so saturated with water as to acquire a liquid’s character.
that is so saturated with water as to acquire a liquid’s character
that is so saturated with water that it acquires the character of a liquid
that is saturated with water enough to acquire liquid characteristics
saturated enough with water so as to acquire the character of a liquid
saturated with water so much as to acquire a liquid character
题目分析：略。
选项分析：
A选项：首先要明确的是，so...as to...与so...that...表达的意思一样，均为“太…以至于…”，一种因果关系。他们的区别在于，so...as to...用于主语和to后面的动作的发出者一致时，而so...that...中，主语与that之后的主语不需要一致。
那相比之下，A B两个选项间没有成分差异，只剩下 of 和 ‘s 的区别。此时，我们需要考虑，liquid作为一个无生命物体，需要用of。
B选项：正确。
C选项：enough需要置于water前面。因为，沙子是和“足够的水”饱和，所以才获得了液体的属性，而不仅仅是“和水饱和”，所以足以获得液体的属性。
D选项：enough不能和so as to 混着用。
E选项：表达“太…以至于…”中没有so much as to的用法。
There are several reasons to eliminate A and choose B.
so X as to Y implies that Y SEEMS TO BE TRUE.
Official examples:
Climatic shifts are so gradual as to be indistinguishable from ordinary fluctuations in the weather.
The features of the idealized sculpture portrait are so unrealistic as to constitute what one scholar calls an "artificial face."
In each case, the blue portion is something that SEEMS TO BE TRUE about the preceding subject in red.
so X that Y implies that Y ACTUALLY HAPPENS.
An official example:
Everyday life is so brisk that it hampers the ability of some children to distinguishing discrete sounds.
Here, the blue portion is something that ACTUALLY HAPPENS -- an action that is actually performed by the preceding subject in red.
A key difference between the two idioms:
Whereas in the second idiom Y can serve to express an actual action, in the first idiom it cannot.
In the first idiom, Y must serve to express not an actual action but merely something that SEEMS TO BE TRUE about the preceding subject.
A: so saturated with water as to acquire a liquid's character
Here, so X as to Y incorrectly serves to express the action in red.
As noted above, Y in this idiom must serve to express not an actual action but merely something that seems to be true about the preceding subject.
Moreover, the usage of so X as to Y implies that the portion in red does not actually happen.
Not the intended meaning.
A person can DROWN in quicksand.
Thus, quicksand actually DOES acquire the character of a liquid.
To express this meaning, we should use so X that Y, as in the OA:
"Quicksand"...is so saturated with water that it acquires the character of a liquid.
Another issue:
A dog's eyes can reveal much about its temperament.
Here, the phrase in blue implies that every dog has UNIQUE eyes -- eyes that can reveal much about the dog's temperament.
A: a liquid's character
This phrase seems to imply that every liquid has a UNIQUE character.
Not the intended meaning.
The intention here is to discuss the general nature of any given liquid.
The OA correctly expresses this meaning:
"Quicksand"... is so saturated with water that it acquires the character of a liquid.
Here, THE CHARACTER of a liquid = the general nature of any given liquid.
For all these reasons, eliminate A.
