Unit 20 Lesson 2 Artificial Intelligence
教材分析
本课是有关人工智能的听力课。学生将要听到三篇有关人工智能的听力材料,分别是:人对“机器人”的访谈, 介绍一不科幻电影《2001:太空漫游》的专题小报告,及电影《2001:太空漫游》的对白节选。学生将通过听力材料了解人工智和机器人,并能用本文将要学习的有关澄清事实和提问题的功能句型来谈论这个话题。也将要练习通过听力材料的关键词来识别说话人,或通过捕捉语言的风格分辨说话人间的关系;学习利用语境预测听力内容和缺失的信息,并复习 note taking的听力学习策略和提高对听力学习策略使用的意识。
本课计划按两课时完成,第一课时重点是通过听力材料掌握澄清事实和提问的功能句型,并能落实到口语当中。第二课时通过听电影《2001:太空漫游》的相关介绍及电影对白节选来学习练习听力策略,主要是在听力前预测相关信息,并在听力过程中写下关键信息;并掌握一些固定搭配的用法。
