【RSB学案23】人教版高中英语必修第一册Unit4 Natural Disasters 第3课时学案（语法专项课 定语从句 关系副词）
作者：Risibo
本套学案遵循日思搏英语学习法（Reasonable English）“背、悟、用”模式，构建实用高效的特色课堂。RSB即Recite（背诵）、Study（领悟）、Build（运用）。
一、狂背阶段·素材输入（课前预习）
1.规则狂背：背诵定语从句关系副词核心规则口诀：关系副词有三个，when where和why；先行表时用when，表地点用where，原因就用why；从句不缺主宾语，缺状就把副词用。
2.例句狂背：背诵5个课本原句+拓展典型句，做到脱口而出，以句带法。例：I will never forget the day when the earthquake happened. / This is the city where the disaster took place.
二、真悟阶段·规律内化（课中探究）
语法本质真悟
关系副词在定语从句中作状语，分别表示时间、地点、原因；本质上都可以替换为“介词+which”结构。
1.关系副词用法梳理
￮when：先行词为时间名词，从句作时间状语 = 介词+which
￮where：先行词为地点名词，从句作地点状语 = 介词+which
￮why：先行词为reason，从句作原因状语 = for which
2.关系代词与关系副词的判断方法核心方法：分析从句内部成分。从句缺主语/宾语，用关系代词；从句不缺主宾，缺状语，用关系副词。❌ This is the village where we visited last year.✅ This is the village which/that we visited last year.（visit缺宾语）
3.高频易错陷阱理性归纳❌ 看到时间名词就用when，看到地点名词就用where（必须分析从句成分）❌ 关系副词在从句中作宾语❌ why的先行词不是reason
课堂实操：口头快速判断用关系代词还是关系副词并说明原因，完成规则内化。
三、神用阶段·输出落地
