Question

【题目】-- I came to your home yesterday afternoon, but nobody was in.

--Oh, we some shopping in the supermarket.

A. have done B. did C. were doing D. are doing

Answer 1

【答案】C

【解析】句意：——昨天下午我来你家，但是没有人。——噢，那时我们正在超市里购物。根据语境理解可知，答语中的动作发生在昨天下午到家那一时刻，强调正在超市购物，故用过去进行时态，过去进行时的构成：主语+was/were+动词的ing+…，句中主语是we，因此该用were，故答案选C。
