内容分析
本篇文章是一篇网络论坛专题讨论，是新媒体语篇，反映了单元主题。文章介绍了三位发帖人分别就“迄今为止，人工智能是人类最伟大的成就还是最大的威胁”发表了不同的看法。Millenniumbutterfly认为人工智能的发展会使日常生活变得更加便利，而在Ppkid看来，能够独立思考的高级人工智能固然能够帮助人类解决许多难题，但也可能对人类的生存构成威胁；Pink_haze则认为我们不应阻止人工智能技术的发展，而是要在发展的同时去规范它。
读前的导入活动以时间轴的形式回顾了人工智能的发展史，为学生提供背景知识，并引导学生初步思考人工智能“是福还是祸”，为课文学习做铺垫。读中活动请学生阅读全文，归纳文中观点，并与自己之前的观点进行对比。读后活动通过细节理解、观点判断、开放性问题等活动，帮助学生深入理解课文，探究主题意义，促进学生知识和思维能力的拓展与迁移。。
