译林版 中考英语语法详解-时间状语从句 时间状语从句在复合句中充当时间状语,用来说明主句动作发生的时间。引导时间状语从句的词称为从属连词。 一、 常见引导词及其用法辨析 1. when, while, as (当...时) 这是最核心的考点,需要仔细区分。 引导词 含义侧重 从句动词特点 例句 when 1. 从句动作与主句动作同时发生。 2. 从句动作发生在主句动作之前或之后。 (用法最广泛) 延续性或非延续性动词均可 1. I was reading when he came in. (同时,came是非延续性动词) 2. When the work was done, we went home. (之后) while 1. 强调主句和从句动作同时发生,且持续一段时间。 2. 表示对比,“然而”。 必须是延续性动词 1. Please don't talk while I am speaking. (同时进行) 2. I like coffee while he prefers tea. (对比) as 1. 强调主句和从句动作相伴发生,“一边...一边...”。 2. 表示变化,“随着”。 延续性动词 1. He sang as he walked. (一边走一边唱) 2. As time went on, she became more confident. (随着时间推移) 简单总结: 能用 when 的情况大多能用 when。 当从句动词是延续性动词(如work, study, live, read, write等)且强调“在...期间”时,常用 while。 当表示“随着”或“一边...一边...”时,常用 as。 2. before (在...之前) & after (在...之后) before: 主句动作发生在从句动作之前。 Before he went to bed, he finished his homework. (他睡觉前完成了作业。) after: 主句动作发生在从句动作之后。 After the rain stopped, we went out. (雨停后我们出去了。) 3. since (自从...以来) 主句通常用现在完成时,从句用一般过去时。 I have lived here since I was born. (我自从出生就住在这里。) 4. until / till (直到...为止) 主句动词是延续性动词(如wait, stay, work, live等),表示动作持续到某个时间点。 I waited until the rain stopped. (我一直等到雨停。) not...until... (直到...才...) 主句动词是非延续性动词(如leave, go, start, finish等),表示动作直到某个时间点才发生。 I did not go to bed until my father came back. (直到我爸爸回来我才睡觉。) 5. as soon as (一...就...) 表示主句动作紧接着从句动作发生。 I will call you as soon as I arrive in Beijing. (我一到北京就给你打电话。) 二、 中考核心考点:“主将从现”原则 这是时间状语从句最最重要的规则,也是中考必考点。 规则: 当主句是将来时(或含有将来的意味)时,时间状语从句必须用一般现在时来代替一般将来时。 结构: 主句 (will/shall/be going to do...) + 时间状语从句 (一般现在时) 示例: I will call you when I arrive at the airport. (正确) I will call you when I will arrive at the airport. (错误) If it rains tomorrow, we will stay at home. (条件状语从句也遵守此规则) He won't go to bed until he finishes his homework. 特别注意: “主将从现”中的“现”指的是一般现在时,还包括现在完成时(强调动作完成)。 I will go to the cinema after I have finished my homework. 三、 中考经典例题分析 1. ( )I'll send you an email as soon as I _ in London. A. arrive B. will arrive C. arrived D. am arriving 答案:A。解析:as soon as引导时间状语从句,遵守“主将从现”原则。主句是将来时(I'll send),从句用一般现在时(arrive)代替将来时。 2. ( )— What were you doing _ your mother was cooking? — I was doing my homework. A. when B. while C. because D. until 答案:B。解析:问句问“当你妈妈做饭时,你在做什么?”,强调两个动作同时持续进行。从句动词was cooking是延续性动词,故用while。 3. ( )Don't talk loudly _ you are in the reading room. A. after B. because C. while D. until 答案:C。解析:句意为“当你在阅览室时,不要大声说话。”表示“在...期间”,且从句动词are是状态延续,用while。 4. ( )We have been good friends _ we joined the same ping-pong team. A. until B. since C. while D. when 答案:B。解析:主句是现在完成时(have been),根据“since+过去时间点”的用法,空格处应填since,表示“自从我们加入同一个乒乓球队以来”。 5. ( )He _ home until he finished his homework. A. didn't go B. went C. doesn't go D. goes 答案:A。解析:考查not...until...结构,意为“直到...才...”。根据从句时态(finished)判断,主句也应用一般过去时,故填didn't go。 学科网(北京)股份有限公司 $$
