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

試題分析：be used to do表示“ 被用來做某事”，be used to doing表示“習慣于做某事”，used to表示“過去常常”。根據題干，本句的意思是“王先生過去常常開車上班，但是現在為了保持健康，他習慣了騎自行車去上班。”所以本題選A。
點評：對于本題很容易受到to后面跟動詞原形的影響，要記住be used to doing是固定用法。
