And what would happen if they did? Would thinking machines work alongside humans or threaten the existence of humans? How would they be punished if they committed crimes or even murdered humans? 写法领悟：本段连续使用了四个疑问句，层层发问，引人深思，既突出了文章的主题，又增强了文章的气势，用在演讲稿中可以调动听众的热情，引起共鸣。 2．赏用词与结构之美 It really boils down to three things — time, cost and technical limitations.We will need time to develop and fine-tune the hardware and software.The initial cost will discourage most people in the beginning but that should be fixed over time. 写法领悟：第一句是本段的中心句，起到提纲挈领的作用。boil down to意为“归结为，基本问题是”，不用于进行时，常用于主题句的写作中。第三句为but连接的并列分句，后面的分句中使用了被动语态，突出强调了动作的承受者(that，指代第一分句的主语)。被动语态的使用使得上下文衔接更顺畅，语意表达更流畅。 ①What do you mean? ______________________________________ ___________________？(疑问句) 你是什么意思？你打算退出吗？你想违背自己的诺言吗？ 针对练笔 (根据提示完成句子) Are you going to drop out? Do you want to break your promise ②__________________________________________— to people's health and the safety of our society. (造成的)损害实际上可以归结为两件事——对人们的健康和对我们的社会安全。 The damage really boils down to two things 命题热点•追根教材 主题写作 本单元主题是“科技发展”，属于“人与社会”的主题语境。针对此类主题，高考在设题时有时会以活动报道、演讲稿、产品介绍等作为载体介绍新型科技产品或前沿科技的新动态等，旨在帮助学生了解科技发展的最新成果和趋势，感受科技改变世界的深远影响，学会更好地融入当下和未来的高科技生活。　　 命题导向 (一)前沿科技 1．have the capacity to analyse massive amounts of data 拥有分析海量信息的能力 2．imitate the complex networks of the human brain 模拟的是人脑的复杂网络结构 3．a major breakthrough　　 一个重大突破 构建语义场 4．a significant advance 一个显著进步 5．develop human-like intelligence发展出像人类一样的智能 6．the forefront of developments in virtual reality 虚拟现实的开发前沿 7．Facial recognition technology with its capacity to analyse a huge amount of data, has come into widespread use. 面部识别技术有着分析大量数据的能力，现在已经得到广泛应用。 (二)科技对生活的影响 1．be applied in many fields 应用于许多领域 2．have a lot of constructive applications 拥有许多建设性的应用 3．give some examples of the practical applications 举几个应用的实例 4．engage students' interest and enhance learning efficiency 吸引学生的兴趣并且提高学习效率 5．allow autonomous machines to do all the work for us 让自动化机器为我们完成所有工作 6．As we become more and more dependent on computers, some scientists are urging us to think about the dangers posed by the advances in AI. 随着我们对电脑的依赖越来越深，一些科学家正敦促我们思考AI的进步所带来的危险。 写作任务——基础写作的建模训练 [题目]　假定你是李华，下个月是你们学校的“科技月”，为此学校将举办一场主题为“科技与生活”的英语演讲比赛。请你写一篇短文参赛，内容包括： 1．科技在生活中的应用；　2.你的感想。 注意：1.写作词数应为80左右； 2．可以适当增加细节，以使行文连贯。 平时勤练笔 [构思与要点表达] 第一部分　描述现象，导入主题 [从教材中学]　In short, this technology is transforming the way we live.

Sergio's parents had trained him to use his left hand from an early age.As he grew up, he was used to not using his right hand.He could write with his left one and do some things with special tricks or techniques.Despite this, in the first days of new school, Sergio always felt like hiding his underdeveloped right hand in his sleeve as if nobody would ever find out if he did so. It didn't take long for someone to learn Sergio's secret.Jeff Wilkins, the teacher of Sergio's engineering class, figured out that Sergio was missing part of his hand and decided to do something for the new student.Jeff had been leading a robotics project in the school and expert in 3D printing technology.Besides, he hoped to take advantage of this hands-on chance to help his robotics students learn more about engineering and how building a robotic hand worked. So in his class, Jeff announced with great enthusiasm, “You're supposed to be engineering, coming up with new ideas and solving issues.Now Sergio needs a new hand, so we'll work together to build Sergio a robotic hand.” His words fueled everyone's curiosity and creativity. For the next four weeks, Jeff and his class including Sergio worked on the project.After some precise measurements and researches, the class put forward a design draft.Jeff made a few adjustments and gave them some practical suggestions.With access to online models and a 3D printer, they eventually created a robotic hand, which was intended to look good and work well, like catching something. 注意：1.续写词数应为150左右； 2．请按如下格式作答。 Then came the final testing day.　 The life-changing gift for Sergio drew huge attention.　 参考范文： Then came the final testing day.The whole class gathered in the science classroom, watching breathlessly as Jeff carefully loaded their self-made robotic hand onto Sergio's right arm.It fitted quite well! So excited was Sergio that his arm trembled slightly.Having put a baseball on the desk, Jeff signed to Sergio to pick it up.Slowly, Sergio extended his right hand and reached for the ball.Successfully he caught hold of it and everyone present broke into cheers! Holding the ball, Sergio couldn't contain his tears.Never in his life did he expect to catch something with his right hand! The life-changing gift for Sergio drew huge attention.Jeff and his students became an instant hit and various media competed to cover the news.When interviewed about the intention of the project, Jeff said, “I intended Sergio's robotic hand to show our support for him.Meanwhile, I hope to foster students' scientific spirit through this hands-on operation.” His students stated that Jeff challenged them to transform abstract concepts into reality, from which they benefited greatly. Soon voluntary donations poured in, which would go to the school's scientific research and help students develop better.   $$
