(二)-ing形式:动词的-ing形式也是一种非谓语动词。-ing形式仍保留有动词的特征,可以带有其所需要的宾语或状语而构成-ing短语。
1、-ing的形式:-ing有一般式和完成式。及物动词的-ing还有主动语态和被动语态,而不及物动词的-ing则没有被动语态。现在以及物动词make 和不及物动词go为例,将其-ing各种形式列表如下:
动词 语态
形式 及物动词make 不及物动词go
主动语态 被动语态 主动语态
一般式 making being made going
完成式 having made having been made having gone
2、-ing形式的基本用法。
(1)作主语:Seeing is believing.百闻不如一见。Talking is easier than doing. –ing作主语时,如果其结构较长,可用it作形式主语,而将作主语的-ing后置。如:It isn’t much good writing to them again. It’s no use waiting here.
(2)作表语:Her job is washing and cooking. My hobby is collecting stamps.
(3)作宾语:①作及物动词的宾语。She likes drawing very much.;②作某些短语动词的宾语。 Mary is thinking of going back to New York.;③ do+限定词(my, some, any, the等)+ -ing,表示“做…事”之意,如:We often do our cleaning on Saturday afternoon. Will you do any shopping on Saturday this afternoon? ④作介词的宾语:Her sister is good at learning physics.;⑤作形容词worth, busy等的宾语:This book is well worth reading. –ing作宾语带有宾语补足语时,要用it作为形式宾语,而将作宾语的-ing后置,如:We found it no good talking like that. Do you think it necessary trying again?
(4)作定语:The sleeping child is only five years old. Do you know the man standing at the gate? 注:-ing形式作定语用时,如果-ing只是一个单词,就位于其修饰的名词之前,如果是-ing短语,就位于其修饰的名词之后,-ing作定语时,被-ing所修饰的名词就是该-ing的逻辑主语。另外,-ing作定语用时,其动作和句子谓语动词所表示的动作是同时进行的,如果不是同时进行的,就不能用-ing作定语,要使用定语从句,如:The girl who wrote a letter there yesterday can speak English very well.
(5)作宾语补足语:We can see steam rising from the wet clothes. 注:当-ing在复合宾语中作宾语补足语用时,句中宾语就是这个-ing的逻辑主语,可以带有这种复合宾语的动词有see, watch, hear, observe, feel, find, have, keep等。
(6)作状语:①时间状语:Seeing Tom, I couldn’t help thinking of his brother. 分词在句中作时间状语时,其前一般可加when或while,如:When crossing street, you must be careful. ②原因状语:Being ill, he didn’t go to school yesterday. ③方式或伴随状语:Mary stood at the school gate waiting for Betty.
3、主动语态-ing完成式的基本用法。主动语态-ing完成式所表示的动作发生在句中谓语动词所表示的动作之前,一般在句中作时间或原因状语用。句中的主语是它的逻辑主语,并且是它所表示的动作的执行者,如:Having answered the letter, she went on to read an English novel.
4、被动语态-ing一般式的基本用法。被动语态-ing一般式所表示的动作是一个正在进行中的被动动作,而且这个被动动作也是和句中谓语所表示的动作同时发生的。它一般在句中作定语或状语用。如:The truck being repaired there is ours.
5、被动语态-ing完成式的基本用法。被动语态-ing完成式所表示的动作发生在谓语动词所表示的动作之前,在句中一般作状语用。如:Having been shown the lab, we were taken to see the library.
