Question

【题目】一Can you tell me at the time of the rainstorm?

一Sorry, I don't know. I wasn't with him at that time.

A. what your brother is doing

D. what was your brother doing

Answer 1

【答案】C

【解析】句意：-你能告诉我你哥哥暴风雨时在干什么吗？-对不起，我不知道。那时我没有和他在一起。本题是宾语从句，应用陈述句语序，所以排除选项B、D。根据答语at the time of the rainstorm以及后文“wasn’t”可知，宾语从句使用过去进行时态。故选：C。
