仁爱版九年级上册英语教学案Unit4Topic3SectionD
2020年精编仁爱版英语资料
SectionD
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。

尽管学生没学过“warn”，但通过英语解释，能知道第一个单词的意思是“警告”，然后再回到短文去寻找哪个单词可能是这个意思。
这就是要培养学生“用英语学英语”的能力。
老师可以利用这个环节来让学生学习新词:
warn,certain,servant。

让学生在重读1a之前，先读1c的问题，带着问题去阅读，有利于提高学生的阅读效率。
老师要在学生回答第4个问题时，顺势点明：
文章所讲的只是可能性。
并指出本话题的目的之一就是要谈论可能性。
通常用这些词来表达可能性：
perhaps,probably,maybe,may,might。

S3:
从句中的谓语动词要和先行词的数保持一致。

其余也要张贴到“英语角”，这样每个小组都会认真对待这个任务。
