非谓语动词考点易混点讲述
动词不定式
动名词
分词
。
一 .不定式
构成: to+动词原形
在句中作用:除谓语动词外的任何成分
It‘s useful to learn English well=To learn English well is useful.
句型 it+be+ adj+ of/for sb+to do sth.
It is important for us to protect the environment.
不定式作主语
不定式作主语,常用it替代,而将真正主语放在末尾
注意:在kind, good, nice, clever等修饰人品质的时候介词用of
It is kind of you to help me.
一些谓语动词后只能跟不定式,这类词表命令,打算或者希望的
如:would like, like, want, wish, hope, plan, expect.
Would you like to see a film this evening?
不定式作宾语
在find,think后跟不定式作宾语,常用it替代,而将真正宾语放于句末。
I find it easy to learn English everyday.
常见的不带to的不定式
Why not do…,why don’t you do, had better (not) do
Would rather do, could/would/will you (not) do
注意:一些使役动词和感官动词也用动词不定式作宾补,这时要
省略to. 这些动词有:一感(feel)、二听(hear, listen to)、三让
(let, make, have)、四看(look at, watch, see, notice) 。但变
为被动语态时要加上to.
常跟不定式作宾语补足语的有ask, want, help, wish, teach,
encourage, invite, warn, allow等。
eg: My mother encourages me to learn Japanese.
不定式作宾语补足语(与宾语有逻辑上的主谓关系)
eg: Lucy asked him to turn down the radio.
不定式作宾语补足语
eg: The teacher was saw to enter the office
作定语 (与宾语有逻辑上动宾关系):
eg: There is nothing to worry about.
作状语(目的,结果,原因):
eg: He opened the door for her to come in.
作表语(常在be动词后,可与主语互换):
eg: His task is to learn hard = To learn hard is his task.
不定式作其他成分
疑问词+不定式(作主语或者宾语(可转化为宾语从句))
eg: can you tell me when to leave?
= can you tell me when you will leave?
