22. 动词不定式是非谓语动词的一种。所谓非谓语动词就 是不作谓语，没有人称和数的变化的动词。不定式是由“to+动词原形”构成。
语法：动词不定式，基本构成形式是“ to + 动词原形”，有时可以不带to ，否定形式为 not to do 。动词不定式没有人称和数的变化，在句中不能单独做谓语 用法：在句中可以做主语，宾语，表语，状语，和宾语补足语
① 做主语：相当于名词或代词的作用，不定式做主语往往用形式主语it 替代，而将不定式置于句尾t eg：
To learn an art is very difficult.=It is very difficult to learn an art. 学习一门艺术很难。
②做宾语：一般跟在谓语动词后
面。 begin, try, need, plan, forget, decide, agree, like 等后面常接动词不定式做宾语。
③ 做表语：常用来表示预定要发生的动作，一般跟在be 动词之后 eg: Your task is to find out the cost by bus
④ 做定语：可以用来修饰人和物，放在被修饰词后面。
eg: The best way to get there is by bus. She wants a big house to live in.
⑤ 做状语：多表目的，结果，原因
eg: They organized a show to raise money.(目的状语) I’m very pleased to hear the good news.(原因状语) He returned home to find his wife waiting for him.(结果状语) ⑥做宾语补足语：“动词+宾语+ to do” 动词
ask, tell, invite, allow, wish等后面多接不定式做宾语补足语，其中make, let, have等使役动词和see, watch, notice, feel, hear等感官动词后面接不带to 的不定式做宾语补足语 eg：I hear him sing in the next room. He asked me to help him. ⑦动词不定式可与疑问词how, what, which, where, when等连用 eg: I don’t know what to do.
⑧动词不定式的复合结构：即不定式用of或for 引出逻辑主语
当形容词表示客观情况，描述不定式的特征性质时常用for引出不定式的逻辑主语
此结构为：it is +adj+ for sb. to do sth., 此类形容词有easy, hard, difficult, interesting等 eg: It’s easy for us to complete the task.
当形容词表示人的性格、品德或主观态度时，用of 引出不定式的逻辑主语 此结构为：it is +adj.+of sb. to do sth, 此类
形容词有nice，kind，good，wise，clever等 eg: It is very kind of you to help me.
