Question

Last night, I          computer games when my mother came into my bedroom. You can't imagine how embarrassed I was then!                       
A. played                   B. was playing              C. have played

Answer 1

B

考查動詞的時態用法。根據句意，母親進入我房間時，我在玩電腦游戲。后面的動作持續時間長，強調正在進行，用過去進行時：was playing。
