1、U4T3SDSection D. Material analysis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个科学价值观：科技发展使人类成为主宰地球的王者，然而这是否又是葬送人类的最终利器呢？因为一切都要等到将来才能知道答案，所以现在所谈论的都只是可能性。这样，本课的功能也就自然而然地呈现了：谈论可能性。中国学生习惯通过汉语学英语，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
2、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。.Teaching aims1. Knowledge aims： 掌握本课的重点词汇和短语，归纳总结定语从句。2.
