译林新版九年级上册 Unit 3 时间状语从句 语法精讲+精练 · 【语法精讲】 在复合句中充当时间状语的从句叫做时间状语从句，用于说明主句动作发生的时间。本单元核心学习三组引导词，考点集中在引导词辨析与时态呼应规则。 一、before /after/when /while 1. before：意为 “在…… 之前”，表示主句动作发生在从句动作之前。 例：Think twice before you make a decision. 2. after：意为 “在…… 之后”，表示主句动作发生在从句动作之后。 例：After he graduated from university, he went abroad for further study. 3. when：意为 “当…… 时”，从句谓语既可以是延续性动词，也可以是瞬间性动词；主从句动作可同时发生，也可先后发生。 例：When I got home, my family were having dinner. 4. while：意为 “当…… 时；在…… 期间”，从句谓语必须是延续性动词，常用进行时态，强调两个动作同时发生。 例：While we were waiting for the bus, it began to rain heavily. 引导词 从句动词类型 时态特点 强调重点 when 延续 / 瞬间均可 各种时态 动作的时间点或时间段 while 仅延续性动词 多用进行时 动作同时发生的过程 二、since /till/until 1. since：意为 “自从…… 以来”。通常从句用一般过去时，主句用现在完成时。 例：I have made many friends since I came to this school. 2. till / until：意为 “直到…… 为止”，多数情况可互换；句首通常用 until，till 更口语化。 肯定句：主句动词为延续性动词，表示动作持续到从句时间为止。 例：I will stay here till/until you come back. 否定句：构成 not...till/until 结构，意为 “直到…… 才……”，主句动词为瞬间性动词。 例：She didn't leave until she finished all the work. 三、as soon as /whenever 1. as soon as：意为 “一…… 就……”，强调两个动作紧接着发生，遵循 “主将从现” 原则。 例：As soon as I receive his letter, I will tell you. 2. whenever：意为 “每当；无论何时”，相当于 every time。 例：Whenever I read this poem, I think of my hometown. 四、核心规则 1. 时态呼应 主句为一般将来时，时间状语从句用一般现在时表将来（主将从现）。 主句为一般过去时，从句用对应的过去时态。 2. 省略结构：当从句主语与主句主语一致，且从句含 be 动词时，可省略从句的主语和 be 动词，构成 “when/while + 动词 - ing” 结构。 例：When (you are) crossing the road, you should be careful. · 【语法精练】（共75题） （一）单项选择（15 题） 1.
