Material analysis本课是九年级第四单元第一话题的第三课时。主活动是1a。1a 通过介绍发明是什么来继续学习一般过去时的被动语态。学生通过完成1a的任务型阅读，知道发明创造并非遥不可及。1b让学生学习归纳中心句。1c把发明创造的步骤进行整合，让学生更加清楚怎样去发明创造。2是个开放性的讨论，让学生在讨论的过程中知道发明无论大小都对我们的生活产生了巨大的影响。3倡导学生自己去发明创造，并通过介绍自己的发明来巩固英语知识。学生学习了本课之后，对发明创造不再感到神秘莫测，从而萌发自己动手的愿望，有利于激发学生的创造精神。3这个写作任务，需要学生独立思考，并运用所介绍的写作小窍门。学生在短时间内难以很好地完成，故留作家庭作业。.
