标题: 问一道prep 45题关于while 和 at the same time

45。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 care, education, and the 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

※句子结构：A recent poll indicates that …，they denounce…，saying…，while supporting…

i.e.。插入语现在分词结构saying…作denounce的伴随副词，while +现在分词结构表示“与…同时”的含义（与

they denounce平行）。

【考点】※句子结构

1) ※句子结构

2) while+doing现在分词表达时间形容词的方式；

3)如果动词在不同选项之间分别是子句与主句的动词，要注意※句子结构是否完整，选项是否有主句。

(A)正确，while doing的特殊用法（详见P1-131补充说明），此处受词子句的引导词that省略了。

(B) but连接对象不平衡，they denounce but supporting。

(D) while引导子句，没有主句；supporting…修饰对象不清楚，有与saying…平行的歧义。

(E)没有主句；it多余。

问我知道A是对的但是why while and at the same time can be used at the same time?

while in this place acts as but ````

but前后动词形式是要严格对称的

B选项but后面要么是和denounce平行的动词support，要么加SVO一个完整的句子

作者: LaDuDu 时间: 2017-5-2 15:49
A 这里的while是用作转折词而不是时间状语引导词，SVO，ing，while at the same time +ing，后面的两个ing的动作发出者都是同一个主语they，并且完全满足伴随状语的同时且真实条件。的确语感读一遍确实是support要和denounce平行，但是排除之后这个是唯一没有问题的选项了
