一、核心考点（中考必背）
1. 基本定义
表示过去某一时刻或某一段时间内正在进行的动作，强调动作的持续性和进行状态。
2. 基本结构
- 肯定：主语 + was/were + doing
- 单数/不可数/I/he/she/it → was
- 复数/you/we/they → were
- 否定：主语 + was/were + not + doing（wasn't/weren't）
- 一般疑问：Was/Were + 主语 + doing?
- 肯定回答：Yes, 主语+was/were.
- 否定回答：No, 主语+wasn't/weren't.
3. 中考必考时间标志词（看到直接锁定时态）
- 过去具体时刻：at 8:00 last night, at this time yesterday, at that moment
- 过去时间段：from 7:00 to 9:00 yesterday, the whole morning
- 引导时间状语从句：when/while（当……时候）
4. 核心用法（中考3大考点）
考点1：过去某一具体时刻正在做某事
例：I was reading a book at this time yesterday.
（昨天这个时候我正在看书。）
考点2：过去某一段时间内持续进行的动作
例：They were watching TV the whole evening yesterday.
（昨天一整晚他们都在看电视。）
考点3：when/while 引导的时间状语从句（中考最高频）
- while + 过去进行时（延续性动作），主句用一般过去时/过去进行时
- when + 一般过去时（短暂性动作），主句用过去进行时
例：
1. My mother was cooking while I was doing my homework.
2. I was walking in the street when it began to rain.
5. 易混区分：过去进行时 vs 一般过去时（中考必辨）
时态 核心含义 关键词
过去进行时 过去正在进行，强调动作过程 at this time yesterday, while
一般过去时 过去完成，强调动作结果/事实 yesterday, last week, just now
例：
- He wrote a letter last night.（昨晚写了信，动作完成）
- He was writing a letter at 8:00 last night.（昨晚8点正在写信，强调过程）
二、中考解题技巧（直接套用）
1. 找时间标志词：看到 at this time yesterday/while ，优先选过去进行时
2. 看从句引导词：
- while 后接延续性动词，多用过去进行时
- when 后接短暂性动词，主句多用过去进行时
3. 辨动作状态：题目强调“过去正在做”，用过去进行时；强调“做过了”，用一般过去时
4. 主谓一致检查：单数用was，复数用were，避免结构错误
