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

解析試題分析：句意：-我昨天下午六點給你打電話，但是沒人接。-哦，我那時正在和我的父母在河邊散步。昨天六點正在做某事，過去某一時刻正在做某事，要用過去進行時態，主語是I，所以系動詞用was。故選B.
考點：考查過去進行時態的用法。
