accustomed to do和doing的区别
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.
