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：B
看了OG上的解释很混乱啊，说什么用平行结构not just because of x, but because of y, 然后又说为了简洁不重复，要删掉because of. 我选了C，我觉得C也很平行啊，not just because of,,, but because of,,, Og上非要说C选项中drugs that are becoming... 是awkward, 可是B选项里也是drugs that are becoming ...啊！！！它怎么就不awkward了呢？ OG出题者喝多了吧。。。。。。

我觉得是having also written这里很awkard 没有见到过用完成时态ING的 形式 做名词短语放在because of之后的作者: Abigale213 时间: 2011-8-23 19:12
你指出的C选项的那里确实读起来很怪，因为如果我想表达because of drugs that are becoming more expensive 这个意思的时候，我肯定会说because drugs are becoming more expensive. 肯定不会用because of的结构。我真的觉得很难用言语表达该怎么解释，但我觉得你多读一读就能读出区别了。
