中考英语过去完成时练习题50题(答案解析)1. By the time he got to the cinema, the movie _____.A. has startedB. had startedC. startsD. started答案解析：B。
本题考查过去完成时的用法。
过去完成时表示在过去某个时间或动作之前已经发生的动作。
句中“by the time he got to the cinema（当他到达电影院的时候）”是一个过去的时间点，电影开始这个动作发生在他到达电影院之前，所以要用过去完成时，即had+过去分词的形式，start的过去分词是started，A选项has started是现在完成时，C选项starts是一般现在时，D选项started是一般过去时，均不符合语境。
2. She told me that she _____ her homework.A. has finishedB. had finishedC. finishesD. finished答案解析：B。
这里考查过去完成时。
“She told me（ 她告诉我）”是过去的动作，而她完成作业这个动作是在她告诉我之前就已经发生了，所以要用过去完成时，结构为had+过去分词，finish的过去分词是finished，A选项has finished是现在完成时，C选项finishes是一般现在时，D选项finished是一般过去时，都不符合此处的语境要求。
3. When I arrived at the party, most of the guests _____.A. have leftB. had leftC. leaveD. left答案解析：B。
这题重点在过去完成时的判断。
“When I arrived at the party（当我到达聚会的时候）”是过去的时间，而大部分客人离开这个动作是在我到达之前就发生了，所以要用过去完成时，即had+过去分词，leave的过去分词是left，A选项has left是现在完成时，C选项leave是一般现在时，D选项left是一般过去时，不符合题意。
