Unit4Topic1SectionD教学设计Ⅰ.Materialanalysis本课是九年级第四单元第一话题的第四课时。主活动是1a和Project。1a通过介绍古今人们如何定位来继续学习一般过去时

的被动语态，同时让学生初步接触并理解现在完成时的被动语态和含情态动词的被动语态。语法和功能部分则让学生通过填空来归纳总结过去时的被动语态和一些常用的功能句。Project部分则体现了“在做中学”的理念。让学

生用英语来介绍自己的发明，无疑会巩固本话题的语言知识并进一步培养和提高学生“用英语做事情”的能力。Ⅱ.Teachingaims1.Knowledgeaims：掌握本课的重点词汇和短语，归纳总结一般过去时的被动语态。2.Skillaims:能够理解

其他形式的被动语态。如:现在完成时的被动语态和情态动词的被动语态。能够在听、说、读、写活动中正确地运用被动语态。Ⅲ.Thekeypointsanddifficultpoints1.Keypoints:W
