12、t 3Discussion1.Do you know anything about Isaac Asimov and his famous Three Laws of Robotics?2.What do you think of these laws？They are not actual scientific laws but rather guidelines for their human programmers to follow to keep our world safe at first glance.The rules seem logical and reasonable,

13、but they also seem outdated.The main benefits are that they can do some kinds of work more quickly,better and cheaper than humans,and that they can do some risky and dangerous jobs for humans.However,they can cause problems.For example,what happens if they no longer serve people or stop following or

26、rakes.如何写科幻故事【写作任务】某科幻文学杂志的TimeTravel栏目正在面向中学生征稿，请你写一篇英文科幻故事投稿。注意：1.词数120左右；2.可以适当增加细节，以使行文连贯。_Writingtask3科幻故事科幻故事写作属于想象性作文。这类题目要求学生创造出从未接触甚至根本不存在的新形象。允许自由想象、自主发挥的空间较大,因此需要灵活的思维和丰富的想象力。科幻故事是用幻想的形式,表现人类在未来世界的物质精神文化生活和科学技术远景,其内容交织着科学事实和预见、想象。特点是内容丰富、奇特,并且情节合理。科幻类作文包括两个主要因素：科学、幻想。科学既要有科学依据，要遵循科学原理。幻想是

27、指对现实中不可能或者目前不可能发生的事情的奇特想象。能够展示科学世界的无限奥秘和神奇，启迪智慧，激励人们不断探索求知，但不是无限制地夸张与虚构。因此在写作时要注意：可以有新奇大胆的想象但要有一定的科学知识作基础，要科学幻想而不是胡思乱想。可以从自己的生活出发进行幻想，寻找题材，可以就如何解决现实或者未来世界中会出现的问题进行合理想象。一、审题定调本写作任务要求写一篇关于时间旅行的英文科幻故事，此类写作需要大胆发挥想象力。本文可首先介绍时间机器的外形和工作原理，其次讲述时间旅行的经历，最后谈谈你的感受。二、谋篇布局本写作任务可分为三部分：第一部分：介绍时间机器的外形和工作原理；第二部分：讲述时间
