Question

— I went to your home yesterday afternoon, but nobody was in.

— Sorry. We________basketball in the gym at that time.

A.play B.will play C.were playing D.have played

Answer

C

【解析】

句意：——我昨天下午去了你家，但没人在家。——对不起。 当时我们在健身房打篮球。

考查时态。play一般现在时；will play一般将来时；were playing过去进行时；have played现在完成时，根据I went to your home yesterday afternoon,可知at that time“当时”指的是“yesterday afternoon昨天下午”，此处指“我昨天下午去你家时，没人在家，当时你们在干什么？”所以用过去进行时表示过去某个时间点正在进行的动作，故选C。
