考点一 动词不定式
1. 动词不定式的形式
基本形式：①to＋动词原形； ②省略to的不定式
否定形式：not to do sth.
动词不定式的句法功能
(1)作主语
It is adj for/of sb to do sth
如：It is important for us to study English.
It is kind of you to help me.
(2)作宾语
①及物动词＋动词不定式，
如：She promised to come at nine o'clock. 她答应九点来的。
②宾语后有宾语补足语，常用it作形式宾语，而将真正的宾语后置，如：I found it important to get up early in the morning.
我发现早上早起很重要。

(3)作宾语补足语

【注意】有一些感官动词和实义动词也用不定式作宾补，这时不定式要省略to。三让(let, make, have)
如：The boss made them work the whole day.
老板让他们工作了一整天。

①作目的状语
常用结构：only to do(仅仅为了), in order to do, so as to do。
如：He ran fast so as to catch the first bus.
他跑得很快，为的是赶上第一趟公共汽车。
(5)作定语。不定式作定语时，要置于被修饰的名词之后，作后置定语。
