Question

Diana used to _________ to work, but now she is used to ________ because the road is crowded and she wants to keep fit.

A.drive; walk B.drive; walking C.driving; walk

Answer

B

【解析】

句意：戴安娜过去常常开车去上班，但现在她习惯步行，因为道路很拥挤，且她想保持健康。
考查非谓语动词。drive开车，驾驶；walk步行。根据第一空前“used to”可知此处用used to do sth.表示“过去常常做某事”，第一空用动词原形drive；根据第二空前“is used to”可知此处用be used to doing sth.表示“习惯于做某事”，第二空用动名词walking。故选B。
