有个问题 虽然ron大神说 最好不要修正错误的句子

但我还是想问问 如果继续用each of which的话，后面的 ...

contributes，因为each 是单数啊

详情可见Ron大神在这里的回复https://www.beatthegmat.com/in-his-experiments-with-gravity-t80376.html

Student：
thanks Ron,
so if C was each of which contributes XXXX - it would have been a correct option then?
as it contains a verb now?

Ron：
yes.

来源：https://www.beatthegmat.com/in-his-experiments-with-gravity-t80376.html贴一下Ron在beatthegmat讲的：

modifiers that start with the relative pronouns “who”, “which”, “that” must actually be CLAUSES. in other words, the modifier must actually contain a VERB whose subject is who/which/that.
this doesn't happen in choice (c); there is no verb present in the modifier. (note that -ing constructions are not verbs!)

the modifier in choice (d) is in a different class of modifiers altogether; you may want to search the forum for “absolute phrase” if you want more information on how this type of modifier works. these kinds of modifiers DON'T involve verbs; they generally have the form COMMA + (PRO)NOUN + ADJ, where ADJ could be either an actual adjective or a modifier that plays the role of an adjective (such as an -ing modifier).
choice (d) uses the absolute phrase modifier correctly: the pronoun is followed by “contributing”, which is an adjective-type modifier.

note that these absolute phrases CANNOT contain verbs; if you put a verb into an absolute phrase, it becomes a run-on.
总结起来就是

• who,which, that关系代词等后面要加从句，从句要包括一个谓语动词
• 而each+V-ing 是一个叫做absolute phrase的东东，通常结构为 Comma+(pro)noun+adj.,这里的adj.可以是一个形容词，也可以是可作为形容词的成分（如V-ing ）
• absolute phrases里面不能有谓语动词
  

翻译如有错误，欢迎指正

D从each的代词用its 一下就排除其他选项了， LSmm 这里的确是独立主格结构。GMAT中看到EACH就要想到3个考点 ...

all和each的用法xdf总结的经验是：句子前半段用all，句子后半段用each。简单粗暴，但是挺管用的，还没有发 ...
