OG12-118求助！！

jingjane

118. The World Wildlife Fund has declared that global
warming, a phenomenon most scientists agree to be
caused by human beings in burning fossil fuels, will
create havoc among migratory birds by altering the
environment in ways harmful to their habitats.
(A) a phenomenon most scientists agree to be
caused by human beings in burning fossil fuels,
(B) a phenomenon most scientists agree that is
caused by fossil fuels burned by human beings,
(C) a phenomenon that most scientists agree is
caused by human beings’ burning of fossil fuels,
(D) which most scientists agree on as a phenomenon
caused by human beings who burn fossil fuels,
(E) which most scientists agree to be a
phenomenon caused by fossil fuels burned by
human beings,

我的疑问是：答案c选项的所有格+-ing形式不简洁啊。如OG12-24题所说：

the -ing form of a verb can be used as a noun
(e.g., running is her favorite sport), but it is often
awkward, particularly when used with a
possessive, as in this case.

请NN帮我解释一下。谢谢啦~

我的理解是：C: is caused by human beings’ burning of fossil fuels 原因是burnin这样一个过程。B： that is caused by fossil fuels burned by human beings 原因是fuels这样东西，意思与原文不同。burned by human beings修饰fuels。

thx a lot~我想知道-ing作为n.是否不简洁，还有所有格是否不简洁？遇到这两种情况怎么办~貌似没有相关讨论，所以就开贴发问，望高手指点啊！！！！

human beings’ burning of fossil fuels

做所有格后的宾语，优先使用名词，所有格后的-ing都是动名词。和所有

格这个规律相同的还有谓语、介词后的宾语。
这是xdf讲课时老师总结的规律，看过的句子多一点就会有点感觉了

我的疑惑是这样的：E中有说caused by fossil fuels burned by

human beings,也就是说fossil fuels burned by human beings 导致了

global warming，当然有一些牵强似乎用human being's burning of

fossil fuels这个过程更加好一点；还有就是同谓语和从句的区别。。。

我都要晕倒了

我说的同谓语和从句的区别在这道题里我是这样迷惑的：我觉得都可以用，当然E是要排除的，但是我排除的原因是因为实在是太罗嗦了！！！！！

嗯，我的意見是，首先DE兩個是非限定性定語從句，在有同位語可以解釋a phenomenon的時候，優先考慮同位語。GMAC是不喜歡非限定性定語從句的，所以在有更優選擇的時候就放棄非限定性定語從句。
其次，B選項 a phenomenon most scientists agree that is caused by fossil fuels burned by human beings，裏面that
放在agree後面有修飾歧義，可能說的是科學家同意的內容，也可能是修飾phenomenon
最後看A ，和B選項類似 to be 之後的東西修飾有歧義
關於caused by fossil fuels burned by human beings和human being's burning of fossil fuels的問題，有兩個by，GMAC一般情況下是優先使用主動語態的，這裡的都是被動語態，而且兩個by連用，句子就顯得非常的wordy。

個人意見，請多多指教

依旧不懂，sb's doing这个用法不是OG明明白白说了不好的么？？？

Manhattan 说GMAT在大多数情况下认为复数不能有所有格，但是不能因为这个去排除一个选项，只有在时间不够的情况下才能去猜不是复数所有格的那一个！
