Unit 5 Nature’s Temper 第3课时 语法课教学设计
教材分析
【What】本课时语篇主题为人与自然——Nature’s Temper（自然的脾气），核心语法板块为Grammar Focus，聚焦过去进行时（Past Continuous Tense）的用法，以及when/while引导时间状语从句的区别与运用。4a环节：通过问答句呈现过去进行时的语境，要求学生划出表示过去持续动作的动词，直观感知“过去某一时刻/时间段正在进行的动作”这一语法概念；4b环节：通过句子合并练习，强化when/while在时间状语从句中的用法差异；4c环节：通过语篇填空，在完整语境中综合运用was/were、when/while，实现语法知识的语用落地；4d环节：通过角色扮演采访，创设真实交际场景，让学生在口语输出中内化语法结构，实现语言运用。 【Why】语篇旨在帮助学生掌握过去进行时的核心用法，理解“过去持续动作”与“过去短暂动作”的时间逻辑，提升在真实语境中描述过去事件的语言能力；引导学生认识极端天气的特点，了解灾害中的应对方式，培养安全意识、应急素养，同时通过“龙卷风拉近邻里距离”的语篇内容，传递“困境中互助、共渡难关”的人文精神，落实人与自然、人与社会的核心素养。 【How】本课时语篇以板块遵循“感知-操练-运用-产出”的语法教学逻辑：以问答句呈现语法结构，让学生在语境中识别过去进行时；通过句子合并、语篇填空，强化语法形式与规则；交际产出（4d）：创设采访情境，实现语法知识的真实运用。语法点聚焦于用过去进行时结构 was/were + doing ，描述过去某一时刻/时间段正在发生的动作；以及 when （接短暂性动作，一般过去时）、 while （接持续性动作，过去进行时）的用法区别；用when/while连接两个过去发生的动作，清晰表达动作的时间先后与伴随关系；在真实场景中（如采访、分享经历）运用语法结构进行口语交际。所有例句、语篇均围绕“极端天气”主题，语言真实、贴合生活，符合初中学生的认知水平；句式丰富：涵盖特殊疑问句、陈述句、时间状语从句等多种句式，覆盖听说读写多维度训练。

It was raining hard while we were driving back.
教学重难点
教学重点：掌握过去进行时的结构、含义及基本用法，能正确使用 was/were + doing 描述过去的持续动作；掌握 when 与 while 引导时间状语从句的用法区别，能正确运用when/while连接句子、完成语篇填空；能在真实语境中运用目标语法进行口语交际，描述极端天气中的经历。 教学难点：准确区分过去进行时与一般过去时，理解“持续动作”与“短暂动作”的时间逻辑，在语境中正确选择时态；灵活运用 when 与 while ，根据动作的持续性/短暂性正确选择引导词，避免时态与引导词的误用；在真实交际场景中，自然、准确地运用过去进行时进行口语输出，实现语法知识的语用落地。
教学过程
