英语语法精讲:不定式

不定式既具有动词的一些特征,又具有名词,形容词和副词的句法功能

否定式:not +不定式

不定式的时态

一般说来,不定式一般式表示的动作有时与限定动词表示的动作同时发生,也有时发生在限定动词表示的动作之后。如:

Who heard him say that?

He seems to know this.

I hope to see you again.

不定式进行式表示动作正在进行,通常与限定动词表示的动作同时发生,如: They are said to be building another bridge across the river.

I happened to be going that way too.

不定式完成式表示的动作发生在限定动词表示的动作之前,如:

I am sorry to have given you so much trouble.

I am glad to have seen your mother.

不定式的句法功能

(1)作主语

To talk with him is a great pleasure.

不定式短语作主语时,为了保持句子的平衡,往往以it作形式主语,而把不定式短语置于谓语动词之后,如:

It’s nice to hear your voice.

(2)作表语

Her wish is to become an artist.

(3)作宾语
