外研版（2024）八年级下册（2024））Understanding ideas教学ppt课件

这是一份外研版（2024）八年级下册（2024））Understanding ideas教学ppt课件，共33页。PPT课件主要包含了教学目标，学情分析，核心语言，主动语态，被动语态，is spoken，are sent，is cleaned，Version 1，Version 2等内容，欢迎下载使用。
通过本课时学习，学生能够：1. 通过观察，总结一般现在时与一般将来时的被动语态的结构特点;2. 借助句子改写和语篇填空形式，正确使用一般现在时与一般将来时的被动语态;3. 通过双人合作，合理使用一般现在时与一般将来时的被动语态口头讨论所选职业的乐趣与挑战。
已学已会：1. 学生已学习并掌握一般现在时和一般将来时的主动语态基本结构和对应时态时间状语；2. 学生能理解并运用常见动词的过去分词形式，如：cleaned, played, watched。已学没会：1. 在语言运用中，学生多使用主动语态表达，但未掌握语态的意义；对此，可通过句子分析进一步讲解并明确语态的意义；2. 学生对于不同职业有一定了解，但是不能准确用英语表述不同职业的挑战和乐趣；教师在授课过程中，可以适度引导学生对课文语篇相关描述的语言表达进行关注和评价。
未学不难：1. 通过例句对比主动和被动语态应用，学生能够理解被动语态的语用功能；2. 学生能通过归纳结构（am/is/are + dne; will be + dne），掌握被动语态的形式规则，并完成句子改写、填空等练习，如：将主动句改为被动句。未学不易：1. 在口语交际或篇章写作中，如何准确恰当地使用被动语态，对于学生来说有一定挑战；为了解决此类问题，教师在课堂活动设置过程中，可以设计由易到难的练习，辅助学生逐步熟练掌握不同时态被动语态的用法。2. 部分学生不能准确将被动语态与一般现在时和一般将来时等时态结合使用；基于此，可复现不同时态时间状语，助力学生理解和应用。
