  【—:动词不定式的形式】对于英语的学习中,关于动词不定式的形式的内容,我们做下面的讲解学习哦。

  动词不定式的形式

  1.作主语。 如:

  To learn English is very important.

  但实际上不定式作主语常用 it来作形式主语,而将不定式移至谓语动词后作真正的主语。

  如上句可表达为:

  It's very important to learn English.

  2.作表语。 如:

  My idea is to ring him up at once.

  3.作宾语。 如:

  I have decided to go to Binjiang Primary School.

  4.作宾语补足语。

  a. ask, want, teach, tell, know, would like, allow等动词后面接动词不定式作宾语补足语。

  如: The policemen asked him to get off the bus.

  b. hear, see, look at, feel, watch, notice, listen to等动词后接不带to的动词不定式作宾语补足语。

  如: We often see Miss Li clean the classroom.

  c. let, make, have这些使役动词后接不带to的动词不定式作宾语补足语。但在被动语态中这些不带to的都须带上to。

  如: In those days the bosses often made the workers work day and night.

  d.动词help接动词不定式作宾语补足语,可带to也可不带to。

  如: Can you help me (to) carry the heavy bag?

  5.作定语。

  a.与被修饰词有动宾关系。如:I have something important to tell you.但如果不定式动词为不及物动词,后面的介词千万不要省略。

  如: Maybe they have three rooms to live in.

  b.与被修饰词有主谓关系。

  如: Mr Liang is always the first to come and the last to leave.

  c.与被修饰之间只有修饰关系。

  如: I have no time to play cards.

  6.作状语,表示目的、原因、方法、方向、结果等。

  如: I'll go to meet my friend at the railway station.

  7.不定式复合结构"for sb. to do sth" 作主语时,常用"It is +adj+ for

  of sb. to do sth"的句式。形容词good, bad, polite, unkind, kind, ice, clever,

  right, wrong, careful等用"It is +adj +of sb. to do sth."

  其他形容词用 for。
