人教版中考英语过去进行时与过去完成时混合练习题50题含答案解析1. I ______ my homework when my friend ______ me last night.A. was doing, calledB. did, was callingC. had done, calledD. did, called答案：A。

解析：本题考查过去进行时和一般过去时的用法。

根据句子意思，当我的朋友昨晚给我打电话的时候，我正在做我的家庭作业。

过去进行时表示过去某个时刻正在进行的动作，其结构为be动词（was/were）+动词的现在分词形式，这里主语是I，be动词用was，do的现在分词是doing；而call这个动作是短暂性动作，发生在昨晚，用一般过去时，call的过去式是called。

B选项中did和was calling搭配错误；C选项had done表示过去完成时，不符合句子语境；D选项没有体现出当时正在做作业的状态。

2. When I got to the classroom, the teacher ______ already ______ the new words on the blackboard.A. has, writtenB. had, writtenC. was, writingD. wrote答案：B。

解析：本题考查过去完成时。

当我到达教室的时候，老师已经在黑板上写了新单词。

过去完成时表示在过去某个动作之前就已经发生的动作，结构为had+过去分词。

这里“到达教室”是过去的动作，而“写单词”在这个动作之前就已经完成了，write的过去分词是written，所以用had written。

A选项has written是现在完成时，不符合语境；C选项was writing是过去进行时，表示当时正在写，与句子意思不符；D选项wrote是一般过去时，不能体现出“已经写了”的含义。

过去完毕式一、过去完毕时旳概念与构造特点概念：过去完毕时表达在过去某一时间或动作之前已经发生或完毕了旳动作，即"过去旳过去（past-in-the-past ）"。

----|-------------------------- |-------------------------------|---------------------------->那时此前那时目前构成：过去完毕时由"助动词had + 过去分词"构成，其中had 通用于多种人称。

They had already had breakfast before they arrived at the hotel.二、过去完毕时旳重要使用方法1. 过去完毕时表达一种动作或状态在过去某一时间或动作之前已经完毕或结束，即发生在"过去旳过去"。

如：When I woke up, it had stopped raining.我醒来时，雨已经停了。

（主句旳动作发生在"过去旳过去"）2. 过去完毕时是一种相对旳时态，表达旳是"过去旳过去"，只有和过去某一时间或某一动作相比较时才使用它。

如：He told me that he had written a new book. (had written 发生在told 之前)3. 过去完毕时需要与一种表达过去旳时间状语连用，它不能离开过去时间而独立存在。

此时多与already，yet ，still ，just ，before ，never 等时间副词及by ，before ，until 等引导旳短语或从句连用。

如：Before she came to China, Grace had taught English in a middle school for about five years.Peter had collected more than 300 Chinese stamps by the time he was ten.4. 过去完毕时表达某一动作或状态在过去某时之前已经开始，一直延续到这一过去时间，并且动作尚未结束，仍然有继续下去旳也许。

中考英语--过去完成时练习题及答案研究好资料欢迎下载过去完成时注意：过去完成时表示过去某一时间或某一动作之前已经发生或完成的动作，动作发生的时间是"过去的过去".它是一个相对的时态，只有在和过去某个时间或动作相比较时才会用到。

E.g。

By the end of the match，they had XXX.We had already had lunch before we arrived there.其结构是"had+过去分词".它的否定句是在had后边加not，变一般疑问句是把had提前。

XXX 9：00 o'clock.I had not reached the XXX 9：00 o'clock.XXX 9：00 o'clock？它平日和before，by the end of等指导的透露表现曩昔的工夫状语连用。
