问题 His father______smoke in the past, so he is in good health now.

选项 A、not used to
B、used not to
C、used to
D、used to not

答案B

解析 句意:他的父亲过去不常抽烟,所以现在身体很健康。一般句中含有“used to+动词原形”结构的,变否定句时,有两种方法:一是在used to的中间直接加否定词not,可缩写为usedn’t;二是借助助动词did,在did后加否定词not(可缩写成didn’t)放于use to之前,used还原成use。此题根据后一句的意思可知,他的父亲应该是过去不常抽烟,所以身体很好。所以本题的答案选B。
