1. used to的一般疑问句有两种构成方法: 1)将used提前至句首,结构为:Used + 主语 + to do sth...? 2)将did提前至句首,结构为:Did + 主语 + use to do sth...? 2. 同样,其否定句也有两种构成方式: 1)直接在used后面加上not,也可一起缩写成usedn't. 结构为:主语 + used not to do sth... 或 主语 + usedn't to do sth... 2)借助于助动词didn't,其结构为: 主语 + didn't use to do sth.... 3. 如: 1)Used he to get up early? = Did he use to get up early? 2) He used not to get up early. = He usedn't to get up early. = He didn't use to get up early.
