(D) in support of the theory that global forest fires were ignited by a meteorite impact and that（B）

这道题答案我选对了，但是我的想法和白勇讲的不一样，就是关于 contributed…… 这个分词短语修饰谁的问题。我觉得 contributed to the extinction of the dinosaurs and……是就近修饰 a meteorite impact 的，而白勇说是修饰 global forest fires 的。他说是全球的森林大火导致 the extinction of the dinosaurs，而不是 meteorite impact导致恐龙灭绝。但是按照分词短语就近修饰原则，难道不是 meteorite impact 导致 the extinction of the dinosaurs 吗？ 请牛牛们指点一下！[em11]

global forest fires ignited by a meteorite impact是主语，ignitedby是过去分词作定语，contributed to是谓语。你可能把contributed to理解成过去分词了。fficeffice" />

1，vi:contribute to sth:导致，促成，使发生。

2，vt:contribute sth t给...,捐sth，贡献sth。 所以sth contributed to sth/sb很容易被理解成 2的被动形式，但这样句子就没有谓语了。
