高中英语（上外版）选择性必修第三册 Unit 2 Cherishing Friendship课时：第三课时 教学内容：Grammar in Use： Complex infinitive一、教学设计与说明1. 教学目标课型： 语法课 本课为本单元的第三课时，核心目标为帮助学生在语篇中识别动词不定式的多种复合结构，理解其意表功能；并能根据表达的需要恰当运用动词不定式的复合结构。2. 设计思路本课为本单元的第三课时，旨在引导学生通过语境的分析，恰当地使用动词不定式的三种时态，主动、被动形式及其否定式。首先通过句型转换的形式，让学生从已有的知识储备引出动词不定式的复合结构，并理解其代表的语义。在该活动之后引导学生完成动词不定式的复合结构的表格填空，再次巩固其时态和语态的表达形式与表意功能。然后，先让学生进行动词不定式的单句填空练习，操练动词不定式的复合结构的表达形式。在此基础上，再设计动词不定式复合结构在语篇中的练习。此环节设计两个练习：练习一让学生阅读一个语篇，根据上下文进行动词不定式复合结构的填空。练习二为小组操练，要求学生借助图片并结合生活实际运用动词不定式，谈谈自己平时在与父母相处中遇到的问题及想法。该活动既操练巩固了语法结构，也让学生了解父母的苦心，实现在真实语境中使用动词不定式的复合结构，让学生体验其表达某种意愿或要求的语用功能。最后为综合运用操练。学生运用已经学过的所有非谓语动词的表达方式，对语篇“表达单一性问题”进行修改，夯实学生的语言综合运用能力。回家作业：1.完成书本 P25 Exercise II。2.完成练习册中的 Grammar In Use 的练习。3. 重点难点动词不定式完成式的被动语态的正确表达及其在真实语境中的使用。Lesson Plan1By the end of this period, students will be able to:1. identify the structures of complex infinitives and understand their meanings in the context;2. properly use complex infinitives in situational context.Procedures:I.
