Question

That’s our new teaching building. But there     old houses here.

A. used to have              B. used to be

C. was used to be           D. was used to have

Answer

B

【解析】

试题分析：句意：那是我们的新教学楼。但是这里过去曾经有老房子。本题前后两句新旧进行对比，现在和过去进行对比，故空缺处是过去有的意思。There be表示存在，“有”，used to过去常常，be used to do sth被用于做某事，故选B。

考点：考查动词短语辨析的用法。
