白勇语法上反复强调：宾语从句的that不能省略，但是请看下面这道GMATprep题（正确答案是A），saying后面不就省略了that吗？大家看这是怎么一回事？

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

有that更好。但是其他选项更不好，B,but后一般加句子； C，两个句子不能就用，连接； 而且SAY后面的句子意思上不能和前面并列； D，E， 没主句了。

还没看过白勇语法，有错请大家纠正。

明白了。谢谢！！！！！！！
