56.        Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxides with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

(A) with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

(B) with atmospheric water vapor producing highly corrosive sulfuric and nitric acids

(C) and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids

(D) and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive（E）

(E) and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

为什么是E不是C啊？

which不能紧跟在n后，要用“," 隔开。 vapor：n.水汽, 水蒸气, 无实质之物
vi.蒸发, 自夸
vt.使蒸发
n.自夸者

那为什么不能 a b 呢，

那个 between 是跟哪个 and 的，怎么知道

dtstruggle

 dioxide and nitrogen oxides ，从词义（如果不认识单词，也可以从构词法看出）他们都是emissions的例子。所以他们之间的and并不是between后面要跟的那个and

15.   Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxides with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

(A) with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

(B) with atmospheric water vapor producing highly corrosive sulfuric and nitric acids

(C) and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids

(D) and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive（E）

(E) and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

Choice A and B are faulty because the idiomatic form of expression is between X and Y, not between X with Y. Also, in choice B producing…modifies the nearest noun, water vapor, rather than chemical reactions and thereby seems to say that the water vapor alone produced the corrosive acids. Choices C and D are clumsy, and both misuse which: in C which has… illogically modifies water vapor, and in D it is unclear whether which have modifies reactions or sulfur dioxide, nitrogen oxides, and water vapor taken together. E is the best choice for this very difficult question.

2楼错了吧，which不可以做非限定修饰吧？也就是前面不可以有，号。which可以做限定修饰，但前面只能是名词或词组（prep里面还是有几题which限定修饰）如果我没记错的话"，which"在prep里面是全错的。这里是错误是which的限定修饰了water vapor而不是Chemical reactions.
欢迎指正
