83. In 2000, a mere two dozen products accounted for
half the increase in spending on prescription drugs,
a phenomenon that is explained not just because of
more expensive drugs but by the fact that doctors are
writing many more prescriptions for higher-cost drugs.

(A) a phenomenon that is explained not just because
of more expensive drugs but by the fact that
doctors are writing
(B) a phenomenon that is explained not just by the
fact that drugs are becoming more expensive
but also by the fact that doctors are writing
(C) a phenomenon occurring not just because of
drugs that are becoming more expensive but
because of doctors having also written
(D) which occurred not just because drugs are
becoming more expensive but doctors are also
writing
(E) which occurred not just because of more
expensive drugs but because doctors have also
written

答案是B。我想请问下，这个句子的结构是什么呀？第二个分句是同位语从句。在整个句子中充当什么成分呢？状语？修饰前面一个分句的同位语从句？

修饰前一个的同位语从句

a phenomenon修饰的是the increase ...

LZ还可以看看104那道

我怎么感觉phenomenon修饰的是前面整个句子呢？

cllcchocolat · 发表于 2011-4-27 03:55:26

修饰整个句子吧...
which只能指代前面最近的名词drugs, 逻辑不对。剩下abc, explained by

同意LS

来翻过去的回复~~~

更正。。。修饰前面整个句子。。。泪奔。。。当时怎么会写成修饰increase。。。

不是同位语从句，就是定语从句指代一个现象。属于大师句型。

同位语的that 不做任何成分

所以说which用在这里是不对的？which在从句中只能修饰离他最近的那个名词，而不能修饰整个句子？为什么og没有指出呢？
