accustomed to do，这个用法是不正确的
be accustomed to 是固定词组，后面连结doing，be accustomed to 后不能接动词不定式
be accustomed to sth习惯于…… （接名词）
例句：It will not take you very long to be accustomed to the way we do it. 你不必花很长的时间就能习惯我们做事的方法.
be accustomed to doing sth习惯于做…… （接动名词）
例句：I am accustomed to eating five meals a day. 我习惯一天吃五餐。
动名词和动词不定式一样，其否定形式也是直接在它前面加not.如：
I get up early in order not to be late for school.
I decided not to do the homework.
I feel like not being disturbed.
I prefer not doing the experiment.
