PREP-75, 很简单的结构题,我越想不明白

75.  A recent poll indicates that many people in the United States hold a combination of conservative and liberal political views; i.e., they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting many specific government programs for health car, education, and environment.

A. they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting

B. they denounce big government—they say that government is doing too much and has become too powerful—but supporting at the same time

C. they denounce big government, they say that government is doing too much and it has become too powerful, while they support at the same time

D. while they denounce big government, saying that government is doing too much and has become too powerful, at the same time supporting

E. while they are denouncing big government—they say that government is doing too much and it has become too powerful—supporting at the same time

答案是:A, 可我觉得while at the same time supporting此处的SUPPORTING 也应该与DENOUNCE平行呀, 为何非得理解为跟SAYING...平行呢? 同理, D为何就错呢? 谢谢大家!!!!

d中while是连词，所以主句的主谓都不能够省略，然而d没有主语，没有谓语，所以是不完整的

而a中，while是介词，可以加ing结构，我记得以前的初中课本上还背过这种结构，可以查字典。所以a的主语，谓语结构是完整的。

同意楼上

WHILE在A D两项中磁性其实不同。

做题的时候主要还是看结构不对就立刻pass吧. D 明显没有主语了。

while 这里应该不是介词，表示时间状语，省略了主谓了，见GWD6-1
