过去完成时练习题(含答案)一、初中英语过去完成时1．She said when she got to the cinema, the film ________ for 5 minutes.A. has begunB. had begunC. has been onD. had been on【答案】 D【解析】【分析】句意：她说当她到达电影院的时候，电影已经开始五分钟了。
根据got 可知，电影开始五分钟属于在过去某时间前已经存在的状态，应该用过去完成时，所以排除A和C。

【点评】此题考查动词的时态问题以及瞬间动词和延续性动词的区别。
2．When I got to school, I realized I ______ my backpack at home.A. leftB. had leftC. forgotD. had forgotten【答案】 B【解析】【分析】句意：当我到学校时，我才意识到我把双肩包落在家里了。
