Unit4Topic1SectionA教学设计Ⅰ.Materialanalysis本课是九年级第四单元第一话题的第一课时。主活动是1a和2。1a通过Kangkang和Jane谈论火箭模型，引入本课的语法：一般过去时的被动语态。1b是检查学生听1a的效果，1c则是检查学生阅读理解的

能力。2重点操练bemadeof，bemadefrom和beusedfor。3a以听的形式让学生加深对2a的句型和1a的语法的理解。3b让学生能够把本课的句型和语法正确地说出来。总之，本课把句型和语法充分地融合到听、读、说当中。Ⅱ.Tea

chingaims1.Knowledgeaims：掌握本课的重点词汇和短语，初步学习一般过去时的被动语态。2.Skillaims:能够在听、说、读、写中正确运用一般过去时的被动语态。3.Emotionalaims:(optional

)鼓励学生要勤思考、有理想、争做未来的发明家。4.Cultureawareness:(optional)了解其他国家的科技发明。Ⅲ.Thekeypointsanddifficultpoints1.Keypoints:Wordsa

m的用法辨析。IwishIcouldgointospacesomeday.It’susedforwritingon.Ⅳ.Learningstrategies通过温习一般现在时的被动语态知一般过去时的被动语态，实现从一般现在时的被动语态到一般过去时的被动语态的转换。通过联系生活实践，来区分bemad

eof和bemadefrom。在交流中，重在表意，不要担心出错。Ⅴ.Teachingaids有关新词的图片/实物（如：数码相机,锁）/录音机/小黑板/PPT。Ⅵ.TeachingproceduresStage(timeperiod)Interacti
