题目内容：

there used to be a hospital here,________?
A isn't there
B wasn't it
C didn't it
D wasn't there

优质解答

选C.
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...
例如：
Used he to get up early?
= Did he use to get up early?
回答：Yes,he used to./No,he usedn't to.
Yes,he did./No,he doesn't.
