这句话语法对么?
Did you used to borrow books from the school library? 或是应该 Do you used to borrow books from the school library?

Answer 1

呃 全错.
这句的陈述句是 You used to borrow books from the school library.
句中第一个动词是used 转化成一般疑问句应该就used 提问.由于used是过去式,所以一般疑问句应该以助动词Did开头.在一般疑问句中,由于有助动词,其对应的动词应该变为原型.
例:
My father gets up early.转化为一般疑问句为：
Does your father get up early
由于gets是单数形式 一般疑问句的助动词也要是单数形式 所以是does
而gets变为原型get.
所以 正确的应该是Did you use to borrow books from the school library
以下补充摘自我的英语课本：
used to 构成疑问时可借助助动词did或直接将uesd移至主语之前,但后者不常用.例如：
Did you use to see each other?=Used you to see each other?你们过去常见面吗.
