Question

【题目】Peter _________ swim, but now he likes it.

A. wasn’t used to B. didn’t use to C. am not used to

Answer 1

【答案】B

【解析】句意：彼得过去常常不游泳，但是现在他喜欢它。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 可知此处表示转折关系，根

据but now he likes it.可知前半句表示过去不喜欢它，故用didn’t used to，故选B。
