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。

Ⅱ.Teachingaims

1.Knowledgeaims：

2.Skillaims:

Ⅳ.Learningstrategies

在“语法和功能”部分，通过和老师同学一起总结定语从句的用法，来整理本话题的语法。

通过讨论pre-reading的问题，预测文章的内容。

在1b,尝试用英语释义来学习英语单词。

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。

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。

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”，这样每个小组都会认真对待这个任务。
