【RSB学案8】人教版高中英语必修第一册 Unit1 Teenage Life 第3课时学案（语法专项课 动名词作主语&表语）
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：背诵动名词作主语、表语的核心规则口诀：动词不能直接当主表，加ing变名词性；作主语谓动用单数，作表语说明主语事。
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：Choosing courses is a big challenge. / My hobby is reading novels.
二、真悟阶段·规律内化（课中探究）
语法本质真悟
动名词核心属性：动词加ing后具备名词性质，因此可充当主语、表语、宾语等名词性成分，本质是“把动作转化为一件事”。
1.作主语
￮位置：句首，谓语动词用单数
￮同义结构：It is + adj./n. + doing sth（it作形式主语）
￮特殊情况：两个并列动名词作主语，谓语动词用复数
2.作表语
￮位置：系动词（be, seem等）之后，解释主语的内容、性质
￮区分：动名词作表语=主语的内容；现在分词作表语=主语的特征（如the book is interesting）
3.高频易错陷阱理性归纳❌ 动词原形直接放句首作主语❌ 动名词作主语，谓语动词用复数❌ 介词后接动词原形（本单元get used to中to为介词，后接doing）❌ 动名词与不定式作主语混淆
课堂实操：口头快速判断句子正误并说明原因，完成规则内化。
