【RSB学案3】人教版高中英语必修第一册 Welcome Unit 第3课时学案（词汇短语专项课）
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.词形狂背：听单元单词录音，跟读核心词汇，同步记忆词性、名词/形容词/动词变形，做到“说一词，牵一串”。核心词清单：impression, challenge, concentrate, strategy, organise, effective, exchange, advantage
2.搭配狂背：每个单词配套2-3个固定短语，边读边写，建立词与搭配的绑定记忆。核心短语：leave an impression on, concentrate on, work out, set a goal, make use of, exchange...with..., be good at, take advantage of
3.例句狂背：每个搭配背诵1个课本原句/简易例句，避免孤立记短语。
二、真悟阶段·规律内化（课中探究）
本阶段核心：理性辨析易混点，归纳考试命题规律，标注高频失分陷阱。
1.impress 词族深度真悟词形链：impress v. → impression n. → impressive adj.搭配：impress sb with sth / leave an impression on sb / be impressive⚠️ 命题陷阱：词性转换题需判断句子成分，名词作主语/宾语，形容词作表语/定语。
2.易混动词辨析真悟
•concentrate on：侧重“全神贯注于（具体任务）”，宾语多为学习、工作
•focus on：侧重“聚焦于（中心话题）”，可接抽象或具体事物
•pay attention to：侧重“注意（细节）”，强调不忽视理性归纳：完形填空语境辨析题，重点看动作的专注程度和宾语类型。
3.名词变形规律真悟动词→名词规则总结：
•impress→impression（动词+ion变名词，表行为/结果）
•organise→organisation（动词+ation变名词）
•challenge→challenger/challenge（兼类词）⚠️ 语法填空考点：词性转换题，需先判断空格在句中所作成分，再变形。
4.短语多义真悟work out 三层含义：① 计算出；② 制定出（计划）；③ 锻炼，需结合语境判断。make use of 被动形式：use be made of，为改错题和语法填空高频考点。
课堂实操：每个考点口头造1个句子，即时验证是否真的吃透用法。
