2026年中考英语语法专题讲义：状语从句

中考英语语法专题讲义：状语从句 一、状语从句的定义与时间状语从句 1. 定义 状语从句是在主从复合句中作状语的从句，用于修饰主句中的动词、形容词或副词，说明动作发生的时间、条件、原因、目的、结果、让步等。中考重点考查时间状语从句和条件状语从句。 2. 时间状语从句的常见引导词 连词 含义 例句 when 当……时候 I was reading when the phone rang. while 在……期间（常接进行时） While she was cooking, I was cleaning. as 当……时候；一边……一边 As he walked, he sang a song. before 在……之前 Finish your homework before you go out. after 在……之后 After he locked the door, he left. until / till 直到…… Wait here until I come back. since 自从……以来 I have lived here since I was born. as soon as 一……就 I will call you as soon as I arrive. 3. 主将从现 时间状语从句和条件状语从句中，用一般现在时表示将来，主句用一般将来时。 连词 例句 when I will tell him when he comes. as soon as He will call you as soon as he gets home. until She won’t go to bed until her mother returns. 口诀：主将从现记心中，从句用现在，主句用将来。 4. not…until 句型（直到……才） 1. I didn’t know the truth until yesterday. （直到昨天我才知道真相） 1. He won’t leave until you arrive. （直到你来他才会走） 【随堂即时练 1】—— 时间状语从句 1. My father was watching TV ______ my mother was cooking in the kitchen.

The little girl didn’t go to bed ______ her mother came back. A. until B. when C. while D. since 二、条件状语从句 1. 常见引导词 if (如果)、unless (除非，如果不)、as long as (只要)。 连词 含义 例句 if 如果 If it rains, we will stay at home. unless 除非；如果不 (= if…not) You won’t pass the exam unless you study hard. as long as 只要 You can go out as long as you finish your work. 2. 主将从现（条件状语从句同理） 条件状语从句同样遵循主将从现原则。 例句： 1. If he comes, I will let you know. 1. Unless you work hard, you won’t pass the exam. 3. unless = if…not 的转换 unless 句型 if…not 句型 I won’t go unless he invites me. I won’t go if he doesn’t invite me. You’ll be late unless you hurry up. You’ll be late if you don’t hurry up. 4. 祈使句 + and / or + 陈述句（条件句的替代结构） 1. Work hard, and you will succeed. = If you work hard, you will succeed. 1. Hurry up, or you will be late. = If you don’t hurry up, you will be late. 【随堂即时练 2】—— 条件状语从句 1. If it ______ tomorrow, we will stay at home. A. rain B. rains C. will rain D. is raining 1.

He got up early so that he could catch the first bus. 1. She studies hard in order that she may go to a good university. 3. 结果状语从句 so…that…, such…that… 表示“如此……以至于……”。 结构 例句 so + 形容词/副词 + that He runs so fast that no one can catch him. so + 形容词 + a/an + 可数单数 + that She is so clever a girl that everyone likes her. such + a/an + 形容词 + 可数单数 + that She is such a clever girl that everyone likes her. such + 形容词 + 可数复数/不可数 + that They are such good books that I can’t put them down. 转换公式：so + 形 + a/an + 名 = such + a/an + 形 + 名 【随堂即时练 3】—— 原因、目的、结果状语从句 1. ______ he was very tired, he went to bed early.

(同时发生) 2. because / since / as 的区别 连词 语气 用法 because 最强 回答 why，表示直接原因 since 较弱 已知的、显而易见的原因 as 最弱 附带说明原因，多置于句首 3. so…that 与 too…to 的转换 so…that 句型 too…to 句型 He is so young that he can’t go to school. He is too young to go to school. The box was so heavy that I couldn’t carry it. The box was too heavy for me to carry. 【随堂即时练 5】—— 易混连词与句型转换 1.
