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:)
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"
