Answer 1

A
試題分析：根據(jù)語(yǔ)境可知此句的含義是過(guò)去你經(jīng)常乘車去上學(xué)嗎。考查的是固定句型結(jié)構(gòu)used to do sth表示過(guò)去常常做某事，現(xiàn)在不做了。其一般疑問(wèn)句的結(jié)構(gòu)要借助助動(dòng)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(píng)：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(guò)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(lái)做某事。
