【易错考点回顾】动词不定式
【易错点睛】
不定式的基本形式为：to+动词原形，有时to也可省略。动词不定式可以充当的成分有：主语，表语，宾语，宾补，定语，状语。
作主语时，常用在it作形式主语引导的句型中。
It+ be + adj. +（for/ofsb.）todo sth.
作宾语时，常跟在动词want,hope, decide, plan, expect, would like等词的后面，而find,think, make等动词通常用在it作形式宾语的句型中，结构为“主语+动词+it+宾补+不定式”。
作宾补时，常用在tell,ask, allow, want, wish, would like, invite, encourage等词后面；而使役动词make,let, have和感官动词feel,hear, listen to, see, watch, notice等后用不带to的不定式作宾补。

作状语时，可表目的，结果，原因等。
Iwent to the library to study English.我去图书馆学英语了。（表目的）
I’msorry to trouble you.我很抱歉给你添麻烦了。（表原因）
