Unit4Topic3SectionD教学设计Ⅰ.Materialanalysis本课是九年级第四单元第三话题的第四课时。主活动是1a和Project。1a通过介绍机器人的迅猛发展，提出一个引人深思的问题：将来机器人还会像人类的仆人一样为人类服务吗？这个看似滑稽的问题其实蕴含了一

语，1b则体现了课程标准所提倡的“用英语学英语”。1c所设置的问题部分与1a有联系，又有一部分需要学生发表自己的观点，也就是要学生有自己的科学观。Project通过让学生“在做中学，在做中用”的方式，来整合本话题的相关知识。但是这个活动需要学

生先收集资料、准备材料，只能在课后完成，故留作家庭作业。Ⅱ.Teachingaims1.Knowledgeaims：掌握本课的重点词汇和短语，归纳总结定语从句。2.Skillaims:能够总结定语从句的用法。能够

谈论可能要发生的事情。能够通过1b,学会“用英语学英语”。3.Emotionalaims:(optional)培养辩证的科学价值观。4.Cultureawareness:(optional)Ⅲ.Thekeypoint

。通过Project,在合作的过程中学习制作英语墙报。Ⅴ.Teachingaids各种机器人的图片/做墙报用的8开的纸/彩笔/一本英英词典/ppt等。Ⅵ.TeachingproceduresStage(timeperiod)InteractionpatternsTeacheracti

thegrammar.Ss:定语从句。S1:还有谈论可能性。S2:定语从句常用的关系代词有：who,which,that.Who用于指人，which用于指物，that既可以指人，也可以指物。S3:从句中的谓语动词要和先行词的数保持一致。

S4：常用maybe,may,might,perhaps,probably来谈论可能性。学生喜欢竞争，渴望得到认可。所以老师要强调：墙报做得好的小组将得到礼物。其余也要张贴到“英语角”，这样每个小组都youaregooda
