非谓语动词的主要句法功能是修饰,作定语、状语、补语(动名词和不定式可以作主语、宾语)。
作状语:
主要依附在谓语动词上,表达另外一层动作含义。根据非谓语动词和谓语动词的先后关系:
主动:
doing(动作与谓语动作同时发生或在谓语动词之后发生,表伴随或结果);
having done(动作发生在谓语动词动作之前,先发生);
to do(表目的、将来)。
被动:
done(被动、完成)
being done(进行、被动)
to be done(将来、被动)
作定语:
修饰限定名词(having done不作后置定语):
the boy sitting under the tree
I have a lot of work to do.
the work being done by John
the work done by John
the work to be done by John
作补语:在复合结构中。
ask sb to do sth
have sb do sth
with a lot of work to do
with the bird flying in the sky
with the work finished
keep the boy waiting
