OG12-83 选项C的疑问

innerwarrior

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

请教下为什么C不对？除了explain和becasue of重复概念以外，because of doctors having also written可以吗？这样的话因为药和医生这样理解是不是有偏差呀？
谢谢啦：）

~~~不可以

一般不优先用because of 来表达原因，因为会让句子focus在了of 后面的名词上，而不是某件事情上，不能很好的解释为什么

另外C选项里，but alos 拆开是不对的

时态的问题也给讲讲呗~

为什么要用现在进行时呢，其实becomes，writes不也行么

答案是B，偶基本明白了
毛毛说的木有错～

我也想顺便问下版主，not just...but also 是不是完全等于not only..but also啊？而且这两个词组中的also是都可以省略吗，还是说必须完整出现？

同问啊 我觉得这里是not... but平行也对啊。。。   also单独用？ 继续求C选项详解（其它选项都明白啦）

1. 原文说的是两个可能的原因，not...but...改变了语义。
2. 支持毛毛的看法，because of 强调后面的名词，不能很好的表达原因。
C项表达确实confusing， 两个原因是："rising drugs price" and "more prescriptions for higher-cost drugs", 而不是C项简单的"drugs and doctors"

欢迎拍砖

baby 一般来说because of 后面 一般是跟名词的，如果要吧sb do sth 作为名词的话至少也应该是sb‘s doing sth

谢谢毛毛：）那时态你觉得有关系吗？是不是在这里完成时现在进行其实都可以啊？
