Question

--- I phoned you at six yesterday afternoon, but nobody answered.
--- Oh, I __________a walk with my parents near the river.

A．am taking

B．was taking

C．took

D．will take

Answer 1

B

解析试题分析：句意：-我昨天下午六点给你打电话，但是没人接。-哦，我那时正在和我的父母在河边散步。昨天六点正在做某事，过去某一时刻正在做某事，要用过去进行时态，主语是I，所以系动词用was。故选B.
考点：考查过去进行时态的用法。
