Question

—Did you notice ________in her office?

—Yes, she was going over our writing.

A.what is Ms. Liu doing B.what Ms. Liu is doing

C.what was Ms. Liu doing D.what Ms. Liu was doing

Answer

D

【解析】

句意：——你注意到刘老师在办公室里干什么了吗?——是的，她在检查我们的写作。

考查宾语从句。what is Ms. Liu doing刘老师在干什么，现在进行时；what Ms. Liu is doing刘老师在干什么，现在进行时；what was Ms. Liu doing刘老师在干什么，过去进行时；what Ms. Liu was doing刘老师在干什么，过去进行时；英语中宾语从句要用陈述句语序，即“引导词+主语+谓语+……”，所以排除A/ C选项，而由主句中的Did可知，主句是过去时，以及回答中的was going over可知，从句也用过去的时态，故选D。
