标题: OG 12 118题 定语从句 [打印本页] 作者: zhongyaya 时间: 2010-8-29 09:24 标题: OG 12 118题 定语从句
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？作者: quellekind 时间: 2010-8-29 21:33
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。作者: zhongyaya 时间: 2010-8-30 06:30
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。作者: shaoyipeng 时间: 2010-8-31 06:32
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。。。作者: chakaji0130 时间: 2010-12-15 16:45
