Unit 2 Be sporty, be healthy Grammar and Usage 教案 高中英语译林版(2020)必修2

一、教学基本信息 二、教学目标 学完本课后，学生能够 掌握 现在进行时被动语态（am/is/are being done）与现在完成时被动语态（have/has been done）的结构、含义、时间标志词；能区分两种被动语态用法，完成句型转换、短文填空、单选等习题；掌握核心词汇及搭配。 依托体育场馆、运动会主题开展双人角色扮演采访；能在口语对话、简短写作中灵活选用两种被动语态描述正在施工和已完工的运动设施。 遵循 “图片观察 — 文本找句 — 自主归纳规则 — 分层练习 — 交际运用” 语法学习路径，提升自主观察、归纳语法规则的探究能力；借助小组对话互助巩固语法结构。 结合社区体育中心、校园运动会场景体会公共健身设施建设的意义；区分两种被动语态表达逻辑，培养严谨时态辨析思维，养成规范英文句式表达习惯。 三、教学重难点 教学重点 现在进行时被动、现在完成时被动的肯定 / 否定 / 一般疑问 / 特殊疑问完整句式结构。 两种被动语态核心语义区分：前者强调现阶段正在进行的动作；后者强调动作完成、对现在造成影响。 教学难点 根据时间提示（now/these days /so far/recently）准确选用对应被动语态。 特殊疑问句中被动结构语序不混淆；写作中自然交替使用两种被动，不重复句式。 四、教学方法 1. 交际教学法：设置运动会记者采访双人角色扮演任务，在真实问答交际中内化被动语态结构。 2. 归纳教学法：先出示例句与语篇，引导学生自主观察、找出被动句子，自行总结两种被动语态结构与含义，教师再补充梳理。 3. 讲授法：针对两种被动语态的区分、易错变形进行精讲点拨，梳理对比易混时态。 五、教学准备 1. 教师准备：体育馆新旧对比图、社区体育中心宣传单原文、语法分层练习题单、运动会采访任务清单、核心词汇讲义。 2. 学生准备：预习运动设施相关词汇；提前通读体育中心宣传单；准备笔记本分类记录两种被动语态结构。 六、教学过程 StepⅠ Lead-in Activity 1: Free talk with pictures Show two pictures: gym under construction & finished gym. Two discussion questions in pairs: What can you see in the first picture What are workers doing What changes can you see in the second finished gym Offer sample sentences for reference: The gym is being decorated these days. The gym has been completely renovated. （设计意图：借助施工、完工对比图片创设直观情景，双人口语交流初步感知两种被动语态语义差异，自然引出本课语法主题。） Step Ⅱ Presentation Activity 1 Read the leaflet & find passive sentences Read Frances’s sports centre leaflet, students underline all passive sentences and classify them into two groups: present continuous passive / present perfect passive, fill in the table.
