2. B.
   used to; is used to go
3. C.
   was used to; is used to going
4. 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。
考点：本题考查use的用法
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。
