--- How does Jack usually go to work? --- He ______ drive a car, but now he ______ there to lose weight.
A．used to, is used to walk
B．was used to, is used to walking
C．was used to, is used to walk
D．used to, is used to walking
答案：D
试题分析：句意：——杰克经常如何去上班？——他过去常常开车去，但是现在他为了减肥习惯步行去那儿。used to do sth“过去常常做某事”，be used to doing sth“习惯做某事”，be used to do sth“被用于做某事”。根据but,可知此处用与now相反的动词used to。第二空根据now可知表示现在习惯步行，故选D。 考点：考查动词短语词义辨析。
