Answer 1

A
試題分析：根據(jù)語境可知此句的含義是過去你經(jīng)常乘車去上學(xué)嗎�？疾榈氖枪潭ň湫徒Y(jié)構(gòu)used to do sth表示過去常常做某事，現(xiàn)在不做了。其一般疑問句的結(jié)構(gòu)要借助助動詞did的形式，構(gòu)成did sb use to do sth故選A。
考點(diǎn)：used to do sth
點(diǎn)評：注意區(qū)分be used to doing sth、used to do sth 、be used as和be used for doing sth四個(gè)個(gè)句型結(jié)構(gòu)的區(qū)別和意義。be used to doing sth是習(xí)慣做某事，used to do sth表示過去常常做某事，現(xiàn)在不做了。be used as是把…用作…be used for doing sth表示被用來做某事。
