Question

Mr. Wang _______drive to work, but now he _______there by bike to keep healthy.

A．used to; is used to going	B．used to; is used to go
C．was used to; is used to going	D．was used to; is used to go

Answer 1

A

试题分析：be used to do表示“ 被用来做某事”，be used to doing表示“习惯于做某事”，used to表示“过去常常”。根据题干，本句的意思是“王先生过去常常开车上班，但是现在为了保持健康，他习惯了骑自行车去上班。”所以本题选A。
点评：对于本题很容易受到to后面跟动词原形的影响，要记住be used to doing是固定用法。
