问题描述:

she used to live alone.but now she _____living alone because she feel lonely
空格处填doesn't used 还是填IS NOT USED TO.

is not used to不习惯
is not used to 的意思是不习惯,还是不习惯这么用?标准答案是doesn't used to,是标准答案错了吗?不可能是doen't used to ( 这种写法本身就错,助动词DOESN‘T后要接动词原形)


注:used to do sth 过去常常做某事。

be /get used to doing sth 习惯于做某事
