过去进行时 语法讲解和语法练习- 2025-2026学年译林版（2024）八年级英语上册

译林版八上必考语法 过去进行时 · 语法讲解 一、概念 过去进行时主要表示过去某一特定时刻正在进行的动作，或过去某一阶段内持续进行的动作。其核心是强调动作在过去的 “持续性” 或 “正在进行中”，而非动作的完成结果。 二、用法 1. 表示过去某一时刻正在进行的动作 句中常含具体时间状语，如at this time yesterday（昨天这个时候）、at 8 p.m. last night（昨晚 8 点）、when/while引导的时间状语从句等，明确动作发生的时间背景。 例句：I was doing homework when the phone rang.（电话响时，我正在做作业。） 2. 表示过去某一阶段持续进行的动作 强调动作在过去一段时间内持续发生，未明确终止时间。 例句：They were building the bridge all last winter.（去年整个冬天他们都在修桥。） 3. 表示过去的计划或将来安排 用于arrive, come, go, leave等表 “移动” 的动词时，可表示过去计划中即将发生的动作，常搭配将来时间状语（如next week）。 例句：She said she was leaving for Paris the next day.（她说她第二天要去巴黎。） 4. 表示委婉语气 动词hope, wonder等的过去进行时（如was hoping, was wondering）可用于提出请求，语气比一般现在时更委婉。 例句：I was wondering if you could help me.（不知您能否帮我个忙。） 5. 表示重复的动作（含感情色彩） 与always, constantly, forever等副词连用，强调动作反复发生，常带有赞扬、不满等情绪。 例句：He was always helping others when he was young.（他年轻时总爱帮助别人。） 三、与其他时态的区别 1. 与一般过去时的区别 维度 一般过去时 过去进行时 动作性质 表示动作已完成（强调结果） 表示动作正在进行（强调过程，未完成） 时间状语 多为笼统时间（如yesterday, last week） 多为具体时刻或阶段（如at 3 p.m. yesterday） 重复动作 表示一次性动作 与always等连用时表示反复发生的动作 例句 She wrote a letter.（信已写完） She was writing a letter.（信可能没写完） 2. 与现在进行时的区别 时间维度不同：过去进行时聚焦 “过去” 的动作，现在进行时聚焦 “现在” 的动作。 例句： 过去进行时：I was reading at 8 p.m. last night.（昨晚 8 点我在看书。） 现在进行时：I am reading now.（我现在在看书。） 3. 与过去完成时的区别 过去完成时强调 “过去的过去”（动作发生在另一个过去动作之前），而过去进行时仅强调 “过去某时正在进行”。 例句： 过去进行时：When he arrived, I was cooking.（他到的时候，我正在做饭。） 过去完成时：When he arrived, I had cooked.（他到的时候，我已经做好饭了。） 四、句式结构 肯定句：主语 + was/were + 现在分词（doing） 例：They were playing football then. 否定句：主语 + was/were + not + 现在分词 例：She wasn't listening to music. 一般疑问句：Was/Were + 主语 + 现在分词？ 例：Were you watching TV at that time? 特殊疑问句：疑问词 + was/were + 主语 + 现在分词？ 例：What were you doing at 9 p.m. yesterday? 五、常见考点提示 语境中时态判断：当句中出现when（此时另一个动作突然发生）或while（两个动作同时进行）时，需结合动作的 “持续性” 判断是否用过去进行时。 典型错误：误将瞬间动词（如die, finish）用于过去进行时（此类动词通常不表持续，需用一般过去时）。 例：错误：He was dying at 5 p.m.（应为He died at 5 p.m.） · 语法练习 一、选词填空 从方框中选择合适的单词，并用其正确形式填空（每词限用一次） watch run rain cook read sleep talk clean play wait 1.
