初三英语,我们老师讲动词不定式,听不懂,谁能解释下动词不定式怎么用?

如题所述

1.作主语
作主语用的动词不定式常常用it替代,动词不定式(或短语)放在后面。例如:
It's easy to get lost in a big city like Tokyo.在东京这样的大城市容易迷路。
It is terrible to see the ship sinking into the sea.目睹轮船沉入大海,真是太可怕了。
2.作宾语
Indians like to eat hot food.印度人喜欢吃辣味食品。
They need to look at a map.他们需要查看地图。
有的动词不定式在作带有补足语的宾语时,前面往往带有形式宾语it。例如:
Do you think it necessary for us to learn to wait?你认为学会等待对我们来说很必要吗?
They improved the software to make it easier for people to use computers.他们改进了软件,使人们使用计算机更简便了。
3.作表语
It seems to be an interesting book.它看起来是本有趣的书。
The old man's job is to take care of the flowers in the garden.这位老人的工作是照料花园里的花。
4.作宾语补足语
He told me not to bring you anything.他叫我不要给你带任何东西。
Who taught you to play the music?谁教你弹这支曲子的?
5.作定语
动词不定式作定语时,要放在它所修饰的名词或代词后面。例如:
In my dreams I always have very difficult jobs to do.我在梦里总是做一些艰难的工作。
Every day he made one of the smaller animals bring him something to eat.他每天叫一个小动物给他带来吃的东西。
6.作状语
(1)表示目的
You can hide under my seat when the conductor comes to check the tickets.当列车员来查票时,你可以藏在我的座位下面。
In his third year,he left Harvard to work for a company called Microsoft.在三年级时,他为了去微软公司工作而离开了哈佛大学。
(2)表示结果
动词不定式作状语表示结果时常与副词too或enough连用。例如:
It's too heavy to carry.太重了搬不动。
The Californian ship arrived too late to save more people.加利福尼亚号来得太晚,没能挽救更多的人。
7.和某些形容词连用
和动词不定式经常连用的形容词有sure,ready,happy,sorry,afraid等。例如:
He's very happy to see his wife.他见到妻子非常高兴。
I'm sorry to trouble you.很抱歉打扰你了。
8.和疑问词who,what,when,where,which,how构成不定式短语作宾语。例如:
I don ... >

动词不定式除了谓语不能做,其他成分都可以。如:我想学好英语。I want to learn English well.
to learn 就是动词不定式做宾语。我有很多作业要做。I have a lot of homework to do. to do 就是动词不定式做定语。To say is easy, to do is hard.
to say, to do 就是动词不定式做主语。My job is to clean the street. to clean 就是动词不定式做表语。(如果我的回答对您有有用,请选择“对我有用”或“好评”,谢谢您对我回答的采纳)

可以表目的,比如:I work hard in order to catch up with you
可以在不定式之前加动词构成固定短语,比如:want to do,wish to do 等
基本上,初中阶段这两种用法就够了
