used to作为情态动词,可直接在used后加not构成否定式,直接将used置于句首构成疑问式,但与一般的情态动词不同的,它也可像普通动词那样借助助动词did构成否定式和疑问式:
He usedn’t 〔didn’t use〕 to come.他过去不常来.
You used to go there,usedn’t 〔didn’t〕 you?你过去常到那儿去,是吗?
Where did you use to live?你过去是住哪儿的?
【注】在现代英语中,used to的否定式和疑问式通常借助助动词did构成(特别是在口语和非正式文体中),而直接将used作为助动词用通常被认为是非常正统或过时的用法.然而有趣的是,有时还可见到以下这种混合形式:
Did you used to be a teacher?你过去是当老师的吗?
They didn’t used to live here.他们过去没住在这儿.
