Question

When my sister was at the train station, her bag ________．

A. stole    B. was stealing    C. was stolen

Answer

C

【解析】

句意：当我姐姐在火车站的时候，她的包被偷了。考查一般过去时的被动语态。A. stole动词过去式；B. was stealing过去进行时；C. was stolen一般过去时的被动语态。根据题干可知主语her bag是动词steal的承受者，所以应用被动语态；结合When my sister was at the train station,可知用一般过去时的被动语态，其结构为was/were+动词过去分词，主语是单数，所以用was，steal的过去分词是stolen；故答案选C。
