120. 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,
答案解析如下：
(A)a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
【错误】 固定搭配：“agree to do sth.”表意为“同意做某事”，因此根据语法，“most scientists agree to be caused……”应翻译为“大多数科学家同意被引起……”，表意不合理。
(B)a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
【错误】 句子意思：“that is caused by”中的“that”实际上是“a phenomenon”的定语从句的引导词，而“most scientists agree”本意上应是定语从句的一部分内容，因此应放在“that”的后方。
(C)a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels,
【正确】 本选项转化为正常的语序后为“most scientists agree (that) the phenomenon(global warming)is caused by human beings' burning of fossil fuels”。而本选项将“phenomenon”前置作为定语从句的修饰对象(即先行词)，用另一个“that”引导定语从句“most scientists agree(that) is caused by……”对“phenomenon”进行修饰，并将“agree”后的“that”省略，于是产生了本选项的结构。“human beings' burning of fossil fuels”正确地表述了“人类燃烧化石燃料”这件事，含
义的重心既不在“human beings”和不在“fossil fuels”而是在“burning”这件事上。
【大意】 WWF宣布，全球变暖，一个多数科学家同意是由人类燃烧化石燃料引起的现象，会通过改变候鸟栖息地环境对候鸟造成巨大伤害。
(D)which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,
【错误】 固定搭配：不存在“agree on as”的用法。
(E)which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,
【错误】 固定搭配：见(A)。
【最优解题思路推荐】
结合固定搭配的用法和语义分析可以排除(C)以外的选项，因此选择(C)。
