D．Did, used to

Answer 1

A

解析试题分析：根据语境可知此句的含义是过去你经常乘车去上学吗。考查的是固定句型结构used to do sth表示过去常常做某事，现在不做了。其一般疑问句的结构要借助助动词did的形式，构成did sb use to do sth故选A。
考点：used to do sth
点评：注意区分be used to doing sth、used to do sth 、be used as和be used for doing sth四个个句型结构的区别和意义。be used to doing sth是习惯做某事，used to do sth表示过去常常做某事，现在不做了。be used as是把…用作…be used for doing sth表示被用来做某事。
