Grammar 动词-ing形式作主语

2

1 动词-ing形式可直接置于句首作主语。

百闻不如一见。

Seeing is believing.= To see is to believe. 2 为了保持句子平衡，通常用先行词it作形式主语，而把真正的主语放在句末。

争论这事是浪费时间。

It's a waste of time arguing about it. 3 ①在It is no use/no good/useless/worthwhile/dangerous/a wase of time/fun等后需用动名词做真正的主语。例如：

It is no use waiting for him any longer. It's a waste of time arguing about it. ②当句型“There is no ..."表示

“不允许，禁止某种行为的发生或存在”时，需用动名词做主语。

There is no joking about such thing.

动词-ing形式作宾语

动词-ing形式既可作及物动词的宾语，也可作介词的宾语。

1 能用动词-ing形式作宾语的及物动词可分两类，一类是只能用动词-ing形式作宾语，另一类是既可用动词-ing形式作宾语，也可用不定式作宾语。
