第一部分 教案
一、基本信息
1.课题:Unit 3 Sea Exploration Learning About Language——非谓语动词综合运用
2.课时:1课时(45分钟)
3.授课年级:高二
4.学科:高中英语
5.教材内容:本课为单元第3课时(Learning About Language),是单元词汇语法专项课。词汇部分围绕海洋探索主题,学习和巩固核心词汇与固定搭配(exploration, voyage, navigation, submarine, marine, ecosystem, biodiversity, breakthrough, set sail, dive into, make discoveries, push the boundaries等)。语法部分系统复习非谓语动词(动词-ing形式与动词不定式)的综合运用,涵盖作主语、宾语、表语、定语、状语、宾语补足语等多种成分的用法辨析。本课以海洋探索主题语境为载体,遵循"观察—对比—归纳—操练—应用"的语法学习路径,通过分层任务帮助学生系统掌握非谓语动词的用法,提升语言运用能力,落实学科核心素养。
6.学情分析
高二学生在必修和选择性必修前期学习中已陆续接触过动词-ing形式和动词不定式的各种用法,对非谓语动词有一定基础。但学生对两种非谓语形式的用法区别掌握不够系统,在复杂语境中容易混淆,综合运用能力有待提高。学生仍存在以下短板:不能准确区分动词-ing形式与不定式作同一句子成分时的差异;在语篇中灵活运用非谓语动词的能力不足;长难句中非谓语动词的分析理解有困难;部分固定搭配和特殊用法记忆不牢固。本课以海洋探索为主题语境,系统梳理非谓语动词的综合用法,落实"教—学—评"一体化闭环教学模式,通过分层操练和语境应用帮助学生巩固提升。

四、教后反思
本课以海洋探索为主题语境,以非谓语动词综合运用为核心语法内容,严格落实"教—学—评"一体化理念。教学流程遵循"导入—观察发现—归纳总结—分层操练—小结—检测—作业"的闭环模式。通过观察发现、对比辨析、系统梳理和分层操练,帮助学生构建完整的非谓语动词知识体系,提升语法运用能力。
现存不足:语法知识点较多,一节课时间偏紧,部分难点讲解不够深入;基础薄弱学生对特殊动词的意义差异掌握不够牢固;语篇操练环节时间较短,学生综合运用能力提升有限;部分学生仍停留在机械记忆层面,语境应用能力有待提高。
后续改进:适当调整教学内容,突出重点难点,必要时分为两课时;设计更多梯度的对比练习,帮助学生突破易混淆点;增加语篇应用操练的比重,在语境中巩固语法知识;设计更多主题相关的写作任务,以用促学,提升综合运用能力;补充更多海洋探索主题的阅读材料,实现语法学习与主题意义探究的融合。
