Question

【题目】_____ Amy met Peter， she with her mum _______ for the bus at the bus station.

A. When; were waiting B. When; was waiting

C. While; were waiting D. While; was waiting

Answer 1

【答案】B

【解析】

试题分析：句意：当艾米遇到彼得时，她跟妈妈正在车站等公交车。非延续性动词与when连用，延续性动词与while连用。Meet是非延续性动词，用when。后句中with是介词，句子的主语是she，with her mom是其定语，因此谓语用单数。故选B。
