be accustomed to中的to个介词,后面如接动词,动词要加ing改成动名词.
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.

,doing 什么时候用? 如 need to do sth 用作介词的to to 有两种构成否定句,例如: I do not want to be criticized. 我不想挨批评。
