C

試題分析：根據(jù)語境可知此句的含義我現(xiàn)在是走著去上學，而以前是騎自行車去上學�？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�，F(xiàn)在經(jīng)常做的事情要用一般現(xiàn)在時，故選C。
點評：固定句型結(jié)構(gòu)be used to doing sth、used to do sth 、be used as和be used for doing sth是四個容易混淆的知識點。要注意他們的區(qū)別和意義。be used to doing sth是習慣做某事，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。
