人教英语八下Unit5语法讲解及习题 过去进行时（Past continuous tense） 一、语法概念与用法详解 过去进行时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“未完成性”。 1. 基本结构 肯定句：主语 + was/were + 动词的现在分词（v.-ing） 否定句：主语 + was/were + not + 动词的现在分词 一般疑问句：Was/Were + 主语 + 动词的现在分词 + ...？ 特殊疑问句：疑问词 + was/were + 主语 + 动词的现在分词 + ...？ 用法示例 肯定：I was travelling on the train then.（那时我正在火车上旅行。） 否定：We were not driving fast when the storm came.（暴风雨来临时我们没开快车。） 疑问：Were you reading when the typhoon hit?（台风来袭时你在看书吗？） 特殊：What were you doing while it was snowing?（下雪时你在做什么？） 2. 核心用法 ① 表示过去某一时刻正在进行的动作 常与时间点标志词连用：at 8:00 yesterday, at this time last night, when 引导的时间状语从句等。 例：When my neighbour called, my family were having dinner.（邻居打电话时，我们一家正在吃晚饭。） ② 表示过去某一时间段内持续进行的动作 常与时间段标志词连用：from 7:00 to 9:00 yesterday morning, while 引导的时间状语从句等。 例：While we were driving home, the strong winds started.（我们正开车回家时，强风刮了起来。） ③ 两个过去动作同时进行 用 while 连接，两个动作都用过去进行时，强调“对比”或“同时持续”。 例：It was raining hard while we were driving back.（我们开车返回时，雨下得很大。） 3. 过去进行时与一般过去时的区别 时态 核心含义 动作特点 常用时间标志 过去进行时 过去某时正在进行的动作 持续、未完成 while, at this time yesterday, when（从句用一般过去时） 一般过去时 过去某时发生并完成的动作 短暂、已完成 yesterday, last week, when（主句用过去进行时） 对比示例 When the typhoon hit（一般过去时，短暂动作）, my family were reading（过去进行时，持续动作）together. We were driving home（过去进行时，持续动作）when the strong winds started（一般过去时，短暂动作）. 4. when vs while 用法对比 连词 引导从句的时态 动作特点 when 常接一般过去时（短暂动作） 也可接过去进行时（持续动作） 可指“时间点”或“时间段”，强调动作的“先后”或“突然发生” while 常接过去进行时（持续动作） 只指“时间段”，强调动作的“同时进行” 例句 When the power went out（短暂动作）, we were making dinner（持续动作）. While we were waiting（持续动作）, Jenny’s sister started to cry（短暂动作）. 二、练习题 基础巩固 一、用所给动词的正确形式填空 1. I ___________ (do) my homework when the typhoon landed. 2.
