2014年高二英语（人教版选修7）教学精品课件：Unit 2 Period Ⅰ.ppt

Although robots have been developed mainly for military(军用的)applications，civilian uses for the technology are growing，according to Michael Toscano，president of the Association for Unmanned(自控的)Vehicles International. “Unmanned systems allow human beings to do their task with an extension of their hands，their eyes and their ears.” “We can put them in the ocean and theyll swim for eight or nine months，collecting data and monitoring ocean pollution，”says Hudson of IRobot. Recently the US Governments Defense Advanced Research Projects Agency(DARPA)displayed a“robotic man”． Instead of depending on remote-control，DARPAs“robotic man”can actually look at some blocks，find one with a special pattern，and move it to a new location.Mandelbaum，DARPAs project manager，says more challenging tasks lie ahead. Some day，a DARPA robot might find a hidden bomb or help a disabled person select a shirt and button it. To advance the technology，DARPA plans to let members of the public write software for the“robotic man”，then sign onto the Internet and watch a model of“robotic man”perform the task. Its one of the ways that robots will help humankind to extend its reach. 教师用书独具演示 ●教学目标 初步掌握本课文中的词汇，浅层次理解课文，了解相关的背景知识。 本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，对下一堂课对课文的全面理解起到一个铺垫作用。 ●教学地位 本单元话题是“机器人”、 “科幻文学作品”、 “科幻小说作家”。内容主要涉及著名的科幻小说作家艾萨克－阿西莫夫的生平简介和他所创作的有关机器人的科幻小说。可以向学生介绍机器人的制造、种类、功能等，再让学生分组列表，把自己所熟悉的科幻文艺形式(科幻故事、电影、电脑游戏、电视剧、卡通)写出来，并进行简单交流。目的在于让他们了解科幻文学作品的一些基本特征和写作方法，自己尝试写简单的科幻小说，并学会欣赏这些优美的文学作品。 ●新课导入建议 首先让学生列举机器人与我们日常生活之间的联系和它给我们带来的便利和不利处。然后通过分组讨论教材第10页的三幅图画，回答图画下面的三个问题，为下面的阅读做好铺垫。 老师要尽量给学生自主学习的时间和空间，通过自学、自做、自悟、自助等方式，让学生更好地体会和理解文章的内容。 演示结束 Ⅰ.篇章结构 阅读文章，然后完成下面表格(每空不超过3词) Title Satisfaction Guaranteed Event A household robot was going to be 1. by Claire.
