Question

A.use to , used to take B.use to , is use to take

C.used to , is used to taking D.used to , is use to taking

Answer

C

【解析】

句意：——那位老人过去常常晚饭后吸烟，但是现在他习惯于散步。

考查动词短语。used to过去常常做……；use to错误结构；is use to take错误结构；is used to taking习惯于做……；is use to taking错误结构；根据句意理解可知，第一空表达的是“过去常常做某事”，英语是used to do sth，所以排除A/ B选项；而第二空表达的是“习惯于做某事”，D选项的结构是错误的，所以应该选择be used to doing，故选C。
