Unit4AmazingScienceTopic1Whenwasitinvented?SectionAⅠ.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Kangk

ang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.Teachingaims1.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.Emotion

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bemadeof和bemadefrom。在交流中，重在表意，不要担心出错。Ⅴ.Teach

要补充。老师在此过程中，顺便解释lock。为了简单明了，老师可以用汉语解释，因为涉及到不少术语，学生难以听withyournakedeyes.But,asforthepaper,youcan’tsee
