Q30:

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.

 

1. a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing
2. 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
3. a phenomenon occurring not just because of drugs that are becoming more expensive but because of doctors having also written
4. which occurred not just because drugs are becoming more expensive but doctors are also writing
5. which occurred not just because of more expensive drugs but because doctors have also written

答案是B。我选的是C，仔细一想，C中的because of太过复杂。但我觉得A和B同时存在的问题是用一个that引导的定语从句修饰phenomenon，不如过去分词作后置定语来的简单。

这道题主要考虑的是平行结构。

平行结构，在SC中要优先考虑。

A和C没有平心，犯了大忌。

A沒有平行
C 句子變成沒有verb
