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。

老师在解释含情态动词的被动语态时，最好用汉语，言简意赅。
不要讲太多，点明即可。
对于本课的定语从句，不要重点讲，让学生知道这种语法现象就行了。
最好用汉语解释。
