OG 12 118题 定语从句

zhongyaya

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,  正确答案
(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,

Logical predication; Rhetorical construction

Th e underlined portion of the sentence is an
appositive defi ning global warming as a
phenomenon caused by the burning of fossil fuels
by humans. Because this appositive intervenes
between the subject (global warming) and verb
(will create) of a clause, it should be expressed as
clearly and economically as possible so as not to
confuse the meaning of the sentence as a whole.

A To be caused and in burning are wordy,
awkward, and indirect.
B Th at is should immediately follow
phenomenon, not agree.
C Correct. Th e phrase human beings’ burning
is more economical than constructions with
prepositional phrases or relative clauses.
D Th e phrasing is wordy and indirect.
E Th e phrasing is wordy and the meaning is
imprecise; it is not fossil fuels that cause
global warming—it is the burning of fossil
fuels by humans.

Th e correct answer is C.
在C选项中是一个定语从句 a phenomenen是做的定语从句中is的主语吗？那most scientists agree是做的什么成分？

1. 在C选项中是一个定语从句 a phenomenen是做的定语从句中is的主语吗？
    回答：  phenomenen是 is 的主语， 但是并不是定语从句，而是global warming 的同位语。 注意GMAT中大量使用的是同位语。同位语紧跟被修饰的词，意义明确，无歧义。


2. 那most scientists agree是做的什么成分？
    that most scientists agree 是修饰 phenomenen这个同位语的定语从句。

非常感谢，一下子醍醐灌顶阿。。。

我突然产生了疑问，这么说就是phenomenon后面两个定语从句修饰他，后面有一题说两个定语从句叠加在一起一般是不合适的。这里怎么解释。既然是两个定语从句同时修饰phenomenon，那一定省略了一个关系代词，省略了哪个？

zhongyaya

结合逻辑题的解释里出现的一个同结构的话：The only point the lawmaker raises that is not strictly economic is about the health consequences。这句话结构和B选项类似，把THAT放到了后面，那么说明B选项是可以当正确选项的。所以我更不明白了。

再看OG，这道题目很搞不懂，那个scientists短语到底是什么？插入语吗？如果是为什么B不可以？ 如果是定语从句为什么 有事Agree， 又是is? 我觉得这道题目OG解释很不清楚，
请大牛来看看啊！

我没看懂LS的B选项对在哪里~
但是我分析的C选项是
a phenomenon that most scientists agree is caused by human beings’ burning of fossil fuels （C）

a phenomenon...是修饰global warming的同位语没有错
其中that most scientists agree是修饰phenomenon的定语从句
结构如下，a phenomenon (that most scientists agree 定从，可以略去，不影响意思) is cause by human...
要不然agree is 连在一起当然奇怪了。。。

若(C)為答案，則完整詞句如下   
The world wildlife fund... ,a phenomenon... is caused..., will create... .

這一題我的疑惑是，兩個逗點之間的同位語，可以為完整子句嗎？
一般我所認知的同位語用法如下
Michael Jordan, a super star of NBA, was retired.

再請各位高手給我意見了，非常感謝！
