【中考英语--过去完成时练习题及答案】在英语语法中，过去完成时是一个非常重要的时态，常用于描述在过去某一时间或动作之前已经发生的事情。它由“had + 过去分词”构成，通常用于叙述两个过去的动作，其中一个是另一个的先决条件。
掌握过去完成时对于中考英语考试来说至关重要，因为它不仅出现在单项选择题中，也常出现在完形填空、阅读理解甚至作文中。因此，熟练掌握这一时态的用法和结构，是提高英语成绩的关键。
一、过去完成时的基本结构
肯定句：
主语 + had + 过去分词（V-ed / V3）
例如：I had finished my homework before I went to bed.
否定句：
主语 + had not (hadn't) + 过去分词
例如：She hadn't eaten breakfast when her mother called.
疑问句：
Had + 主语 + 过去分词？
例如：Had they arrived before the meeting started?
二、过去完成时的常见使用场景
1. 表示在过去某个时间点之前已经完成的动作
常与“by the time”、“before”、“when”等引导的时间状语连用。
例句：By the time we got to the station, the train had left.
2. 叙述过去发生的两个事件，强调先后顺序
第一个动作发生在第二个动作之前。
例句：He had already left when I arrived.
3. 在间接引语中
当主句是过去时，从句中的动作发生在主句动作之前时，需用过去完成时。
例句：She said she had finished her work.

四、练习题解析
题目1：
By the time we reached the cinema, the movie ______.
分析：本题考查的是过去完成时的使用。因为“we reached the cinema”是过去的一个时间点，而“the movie”在我们到达之前就已经开始，所以要用过去完成时。正确答案是 A. had started。
题目3：
When I got home, my sister ______.
分析：“got home”是过去时，“my sister”在“我回家”之前已经离开，所以应该用过去完成时。正确答案是 A. had already left。
五、小结
过去完成时虽然结构简单，但在实际应用中需要结合上下文来判断动作的先后顺序。中考英语中对这一时态的考察主要集中在句子的时态搭配、时间状语的使用以及逻辑关系的判断上。
建议同学们多做相关练习题，通过反复训练来加深对过去完成时的理解和运用。同时，注意积累常见的搭配和固定表达，如“by the time”、“before”、“after”等，有助于提高解题效率和准确性。
