【题目】There ______ a supermarket across the street but now it has been pulled down.
A. used to be B. used to have
C. was used to be D. used to being
在线课程【答案】A
【解析】考查情态动词。句意：过去在街道对面有一个超级市场，但是现在被拆除了。used to do sth.表示“过去常常”；be used to do sth.表示“被用来做某事”；there be句型不能与实意动词have连用，there used to be…表示“过去有……”。故选A。
