Unit2语法(时间/地点状语从句)导学案--2026-2027学年教科版五四学制英语九年级上册

Unit2 Everything changes语法讲解与练习 语法：时间状语从句&地点状语从句 （一）时间状语从句 定义：在复合句中作时间状语,用来修饰主句谓语动词,说明主句动作发生、进行、结束的时间。 1. 常用引导词及核心用法（必考） when（当……时候）：可指瞬间动作或持续动作，适用范围最广。 例句1：When he was young, he lived abroad.（他小时候在国外生活。） 例句2：I will call you when I finish my homework.（我写完作业就给你打电话。） while（当……时候）：仅接延续性动作，从句常用进行时态。 例句1：While she was reading, I was cleaning the room.（她看书的时候，我在打扫房间。） 例句2：Don’t make noise while others are studying.（别人学习时不要吵闹。） since（自从……）：主句常用现在完成时，从句用一般过去时。 例句1：He has changed a lot since he settled down here.（自从在这里定居，他变了很多。） 例句2：We have been friends since we met ten years ago.（自从十年前相识，我们一直是朋友。） until/till（直到……）：主句延续动作用肯定，瞬间动作用否定（not...until）。 例句1：I will wait until you come back.（我会一直等你回来。） 例句2：He didn’t go to bed until he finished his work.（他直到完成工作才睡觉。） as soon as（一……就……）：主从句动作紧密衔接，遵循“主将从现”。 例句1：As soon as he arrives, we will start the discussion.（他一到，我们就开始讨论。） 例句2：I will tell you the news as soon as I hear it.（我一听到消息就告诉你。） 2. 核心考点与易错点 主将从现原则：when/while/as soon as/until 引导时间状语从句，主句为一般将来时，从句用一般现在时表将来。 例句1：He will go abroad when he graduates.（他毕业后将要出国。） 例句2：I won’t leave until he comes.（他不来我就不走。） while 特殊用法：从句必须用延续性动词，不可接瞬间动词（come/start/finish）。 例句1：While we were chatting, the rain stopped.（我们聊天时，雨停了。） 例句2：误：While he arrived... 正：When he arrived... since 固定句型：It is + 时间段 + since + 一般过去时。 例句1：It is five years since he studied abroad.（他出国留学已经五年了。） 例句2：It is a decade since we met last time.（我们上次见面已经过去十年了。） （二）地点状语从句 定义：在复合句中作地点状语，修饰主句动词，说明主句动作发生的地点、场所。 1. 核心引导词及用法 where（在……地方）：最核心引导词，泛指任意地点。 例句1：Put the book where it belongs.（把书放回原处。） 例句2：We will camp where there is clean water.（我们将在有干净水源的地方露营。） wherever（无论哪里）：强调无条件，相当于 no matter where。 例句1：Wherever you go, I will follow you.（无论你去哪里，我都跟着你。） 例句2：Wherever he studies, he always works hard.（无论在哪里学习，他都很努力。） 2. 核心考点与易错点 区分定语从句与地点状语从句：地点状语从句 where 前无地点名词，直接修饰动词。 例句1：We live where the air is fresh. （状语从句，where前无先行词，我们住在空气清新的地方。） 例句2：This is the village where we live.（定语从句，where修饰先行词village。） wherever 让步含义：引导让步状语，表“无论何地”，可替换 no matter where。 例句1：Wherever you travel, you should keep polite.（无论你去哪里旅行，都要保持礼貌。） 例句2：Wherever the exchange students go, they learn new culture. （交换生无论去哪，都能学习新文化。） （三）重难点总结 1.时间状语从句重点掌握：主将从现、since时态、while延续性用法、not...until； 2.地点状语从句重点掌握：where/wherever用法、与定语从句的区分； 3.所有状语从句：从句语序一律陈述语序，不倒装。 【配套练习】 大题一：单项选择 ( )1.
