          試題分析:be used to sth習(xí)慣于某事;used to do sth過去常常做某事. sth be used to do sth某物被用來做某事。句意:你過去常常乘公交去學(xué)校,是嗎?——是的。然而,我現(xiàn)在習(xí)慣了步行去學(xué)校。結(jié)合語境可知選B。
          點評:used to的用法比較固定,需要注意的是used to do表示過去常常做某事,be used to表示習(xí)慣于某事。前者to是不定式符號,后接動詞原形。后者to是介詞,后接名詞或者名詞性短語。Used to do結(jié)構(gòu)中use相當于行為動詞,有詞形變化。Be used to中used相當于形容詞,無詞形變化。
