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.
