问题补充：

My father live in the country. But now he living in the city.

A used to, is used to B is used to , used to

C use, used to D used to , is used to

答案：

解析：A 考查used to 的用法。used to do sth.“过去常常做某事”；be used to doing sth.“习惯于......”；be used to do sth.“（某物）被用做......”。“我的父亲过去住在乡村，但是现在他习惯于生活在城市了。”故选A。
