【RSB学案38】人教版高中英语必修第二册 Unit2 Wildlife Protection 第3课时学案（语法专项课现在进行时的被动语态）

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：背诵现在进行时被动语态核心规则口诀：现在进行被动态，am/is/are加being done；表正在被进行，动作正在发生中；疑问be提主语前，否定be后not添。

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：The antelopes are being protected by the government. / A new reserve is being built in the area.

二、真悟阶段·规律内化（课中探究）

语法本质真悟

现在进行时的被动语态，表示"某事正在被做"，强调动作正在进行且主语是动作的承受者。

1.基本结构肯定式：am/is/are + being + 过去分词否定式：am/is/are + not + being + 过去分词疑问式：Am/Is/Are + 主语 + being + 过去分词？

2.基本用法① 表示此时此刻正在进行的被动动作例：The wounded animal is being treated by the vet.② 表示现阶段正在进行的被动动作（但此时此刻不一定在进行）例：A new nature reserve is being built in this area.③ 与always, constantly等连用，表感情色彩（被动）例：The rare birds are always being protected by the volunteers.

3.高频易错陷阱理性归纳❌ 漏掉being，直接用am/is/are + 过去分词（变成一般现在时被动）❌ being后接动词原形，不接过去分词❌ 不及物动词用于被动语态（不及物动词无被动）❌ 现在进行时被动与一般现在时被动混淆（前者强调正在进行，后者强调经常性、习惯性）

课堂实操：口头快速把主动句改为被动句，完成规则内化。

三、神用阶段·输出落地
