Question

—Did you know ________ at this time last night?

—Yes. She was drawing pictures in her room.

A.what was Kate doing B.what Kate was doing

C.what did Kate do D.what Kate did

Answer

B

【解析】

句意：——你知道凯特昨晚这个时候在做什么吗？——是的。她在房间里画画。

考查宾语从句。根据句意理解及句中的时间状语at this time last night可知，这里问的是过去某个时刻正在进行的动作，所以这里应该用过去进行时，所以排除C/ D选项，而宾语从句要用陈述句语序，所以这里B选项是合适的，故选B。
