Section 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 aims 1.

The key points and difficult points 1. Key points: Words and phrases: certain, for certain, on ones own, warn, might, housework, so far, be surprised at, no longer Sentences: No one knows for certain, but most people think that robots will be part of our lives. In a few years, perhaps robots will think on their own, just as people use their brains and act for themselves. One scientist warns that if robots start to think for themselves, they will no longer want to be our servants, but our masters. Grammar: summarize the attributive clause, talk about possibilities 2. Difficult points： The scientist also warns that if we are lucky, they might treat us as we now treat our pets. Perhaps there will be a war between human beings and robots. In a few years, perhaps robots will think on their own, just as people use their brains and act for themselves. However, once robots can think for themselves, problems may appear. .
