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)。
D：agree on as a... VS agree(that) is
同时C的burning of fossil fuels 没有human beings burn fossil fuels好，但选项中无。再次说明了相对性错误不能作为eliminate的原则。
可以理解为：a phenomenon that （most scientists agree） is caused by human beings' burning of fossil fuels.
仔细一看，这并不是preposition+noun+verbing的结构。。。这就是介词+名词的结构。。。human beings' burning， 这里是human beings' 是所有格，形容词性，跟Burning连在一起构成一个名词。所以下次还是要看仔细呀
Ron对此反复举例说明，怎么用名词性结构来形容一个动作？要用“所有格”结构。即“sb\'s doing/done”。例如: People laughed at my walking to the classroom, 人们笑的既不是我也不是教室，而是我走向教室的这个动作。
Ron不是这样说的。他的意思大概是有些情况当成没’来看登录 或 注册 后可以参加讨论
A选项：'to be caused' , 'in burning' are wordy, awkward and indirect;
B选项：'that s' should be followed immediately by 'a phenomenon', 中间不要夹着most scientists agree; caused by ‘the burning of fossil fuels'这件事，而不是fossil fuels
C选项：human beings' burning of fossil fuels比介词＋fossil fuels强多了；
D选项：caused by ‘the burning of fossil fuels'这件事，而不是human beings’
E选项：caused by ‘the burning of fossil fuels'这件事，而不是fossil fuels
同问
我感觉约束力这种东西太玄了，好多感觉是知道答案之后硬套进去的登录 或 注册 后可以参加讨论
就是定语从句里又一个从句，先行词在第二个从句中做成分，这句话展开就是a phenomenon that most scientists agree that (a phenemonon) is caused by human being's burning of fossils. a phenonemon在第二层中的宾语从句里做主语登录 或 注册 后可以参加讨论
是啊，你看，你在中文里也说煤的“燃烧”。所以，必须让burn当核心词呀。登录 或 注册 后可以参加讨论
