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 phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels,
which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,
which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,
题目分析:
本题的划线部分是global warming的同位语或者定语,它的变化并不影响整个句子主干的表达。
选项分析:
A选项:首先我们需要先把这个句型看懂,由于先行词a phenomenon在其身后的定语从句中充当宾语,所以这里省略了引导词that,补全则有:
a phenomenon that most scientists agree to be caused by human beings in burning fossil fuels
在定语从句中,若将先行词代入位置,则有:
most scientists agree a phenomenon to be caused by human beings in burning fossil fuels
在本选项中,引起这个现象的是human beings in burning fossil fuels,这个名词短语中的核心词是human beings。但在逻辑上,真正引起气候变暖的应该是人类焚烧化石能源这个行为,而不是人类本身。
另外,agree A to be B不是正确的表达,应该用agree that A do B。(考查“不定式和从句的区别”,由于agree的约束力较弱,所以必须用宾语从句)
B选项:本选项中先行词a phenomenon实际上是做agree的宾语从句中的主语,即:
most scientists agree that a phenomenon is caused by fossil fuels burned by human beings
同(A)理,正引起气候变暖的应该是人类焚烧化石能源这个行为,而不是化石燃料本身。
C选项:Correct. 本选项在语法和逻辑上均是正确。本选项a phenomenon身后的定语从句学名叫嵌入式关系分句。
D选项:cause逻辑主语的核心词错误同(A)。
E选项:cause逻辑主语的核心词错误同(B)。
B答案感觉agree that缺少主语?或者that指代phenomenon?
不少。注意解析中的关键字“嵌套式关系分句”。
同问 B 选项,除了核心词错误外,是否that 的位置并没有构成嵌入式关系分句?
C 选项是很明确的嵌入式关系分句,能明白:
a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels
=a phenomenon that (先行词,在后文做主语) most scientists agree (that) is caused by human beings' burning of fossil fuels
因此 B 选项that 的位置就错了。老师,是么?还是说 B 选项本身的嵌入式关系分句并没有错误?
a phenomenon most scientists agree that (宾语从句的 that)is caused by fossil fuels burned by human beings (没有先行词?)
同问,B是不是嵌入式
感觉是倒装而已

对,agree A to be B不是正确的表达,应该用agree that A do B
