八下英语 Unit5 Nature’s Temper 语法精讲精练 一、核心语法：过去进行时（单元必考） （一）概念 表示过去某一具体时刻 / 某一时间段正在进行或持续发生的动作，常用来描述自然灾害发生时人们正在做的事。 （二）基本结构 · 肯定句：主语 + was/were + 动词 - ing + 其他 单数主语（I/he/she/it/ 单数名词）→ was 复数主语（we/you/they/ 复数名词）→ were · 否定句：主语 + wasn’t/weren’t + 动词 - ing + 其他 · 一般疑问句：Was/Were + 主语 + 动词 - ing + 其他？ 肯定：Yes, 主语 + was/were. 否定：No, 主语 + wasn’t/weren’t. · 特殊疑问句：疑问词 + was/were + 主语 + 动词 - ing + 其他？ （三）时间标志词 · at…yesterday（at 8:00 last night） · at this time yesterday/last week · at that time/moment · when/while 引导的时间状语从句 · the whole morning/afternoon/all day yesterday （四）三大核心用法 1. 过去某一具体时刻正在进行 What were you doing at the time of the rainstorm? 2. 过去某一时间段持续进行 We were waiting for the bus from 7:00 to 7:30 yesterday. 3. 与 when/while 连用（背景动作 + 突发动作） 4. when + 短暂动作（一般过去时），主句 + 过去进行时 When the storm came, I was reading at home. 5. while + 持续动作（过去进行时），主句 + 一般过去时 While I was reading, the storm came suddenly. 二、when 与 while 用法辨析（必考点） 连词 后接动词特点 时态常用搭配 例句 when 可短暂 / 可延续 从句一般过去时，主句过去进行时 When I got home, it was raining. while 只能延续性动词 从句过去进行时，主句一般过去时 While it was raining, I stayed home. 三、过去进行时 vs 一般过去时（易错点） · 过去进行时：强调过去正在做、持续做（动作未完成 / 在进行） · 一般过去时：强调过去做过、已完成 He wrote a letter last night.（昨晚写了信，完成） He was writing a letter at 8 last night.（昨晚 8 点正在写信） 四、单元高频固定搭配（本单元重点） 1. 灾害场景常用短语 · at the time of the rainstorm 在暴风雨来临之时 · wait for the bus 等公交车 · walk home 步行回家 · go off （闹钟）发出响声 · take a hot shower 洗热水澡 · miss the bus 错过公交车 · pick up 接电话；捡起 · make one’s way to 前往；费力地前进 · hear clearly 听清楚 · fall asleep 进入梦乡；睡着 · die down 逐渐变弱；逐渐消失 · wake up 醒来 · in a mess 凌乱；一团糟 · break…apart 使…… 分离 · bring…closer together 使…… 更亲密 2. 本单元重点句型 · What were you doing when…? · I was…when… · While…, …was/were doing… 五、助记口诀 过去进行时很好记，was/were 加 ing；具体时刻在进行，一段时间持续行；when 接短暂 while 接长，背景突发要分清。 · 第一句“过去进行时很好记，was/were 加 ing”：核心对应过去进行时的基本结构，单数主语（I/he/she/it等）用was，复数主语（we/you/they等）用were，后面跟动词的-ing形式，是最基础的记忆要点，贯穿本单元所有句式。 · 第二句“具体时刻在进行，一段时间持续行”：对应过去进行时的两大核心用法—— 1 具体时刻（如at 8 last night、at this time yesterday）正在发生的动作； ② 某一时间段（如from 7:00 to 7:30 yesterday、the whole morning）持续发生的动作，贴合本单元灾害场景中“某一时刻/时段人们正在做的事”的语境。 · 第三句“when 接短暂 while 接长，背景突发要分清”：对应本单元必考点—— when和while的用法辨析，以及过去进行时与一般过去时的连用。 “短暂”指when后可接短暂性动词（如came、arrived），对应突发动作； “长”指while后只能接延续性动词（如reading、cooking），对应背景持续动作，轻松区分“背景动作+突发动作”的句式结构。 六、实战演练 一、用所给动词的适当形式填空 1.
