The development of high­tech is both a blessing and a curse. 高科技的发展又确实是一柄双刃剑。 主题语境——人与社会。在计算机科学中，“人工智能”一词用来描述模仿人类与其他人类思维相关联的“认知”功能的机器。 Artificial intelligence Artificial intelligence (AI)① is the ability of a computer program or a machine to think and learn. It is also a field of study that tries to make computers “smart”. John McCarthy, a scientist, came up with the name “artificial intelligence” in 1955.Many things such as learning and problem solving can be done by computers, though not in the same way as we do. An unusual goal of AI research is to create computer programs that can learn, solve problems, and think logically②. At present we use the term AI for successfully understanding human speech, recognizing human faces, operating self­driving cars and competing in some game systems like Chess and AlphaGo③. Some people also consider AI a danger to humans if it develops too quickly. Professor Stephen Hawking, a well­known British scientist, was not for this kind of technology. Math is the basic language of AI. If we raise the standard in the learning of math, our students will be more likely to become successful AI designers in the future. We not only want bright students, but also need to attract average students and give them the math skills which are needed to change them into AI designers. Besides, a good knowledge of computer science is also necessary for AI designing. Scientists hope to create creative and emotional④ AI which can possibly understand human feelings or create art. Many ways and tools have been tried to discover this fascinating⑤ field. ①Artificial intelligence (AI)人工智能 ②logically adv.合乎逻辑地 ③AlphaGo阿尔法围棋 ④emotional adj.感情的；情绪的 ⑤fascinating adj.迷人的 Section Ⅰ　Welcome to the unit and Reading—Preview [对应学生用书P80] 1．castle n．城堡 2．input n．输入的信息；投入vt.输入(信息) 3．capacity n．领悟(或理解、办事)能力；容量，容积；职位，职责；生产量 4．analyse (AmE analyze) vt.分析 5．massive adj.巨大的，大而重的；非常严重的 6．coin vt.创造(新词语) 7．finance n．财政，金融；资金；财力，财务管理 vt.提供资金 8．autonomous adj.自主的，有自主权的；自治的 9．domestic adj.家庭的，家用的；本国的，国内的 10．threaten vt.危及，对……构成威胁；威胁，恐吓 11．crime n．罪，罪行；犯罪活动 12．urge vt.敦促，催促；大力推荐，竭力主张；驱赶，鞭策n.冲动，强烈的欲望 13．pose vt.造成，产生；提问，质询 vi.摆好姿势 n．姿势 14．demand vt.需要；强烈要求 n．要求，所需之物；需求，需要 15．victim n．受害者，牺牲品；受骗者；祭品 Step 1　Fast reading Check yourself to what degree you have remembered the text by filling in the blanks in the following passage.

As a branch of computer science, artificial intelligence (AI) aims 1.to create (create) intelligent machines. To achieve this aim, many approaches to 2.creating (create) true AI have been put forward. Although AI technology developed very slowly for a long time, a major breakthrough in AI came in 1997，3.when Deep Blue beat the world chess champion Garry Kasparov. Twenty years later, a computer program 4.named (name) AlphaGo defeated Ke Jie, which demonstrated a significant advance in deep­learning AI systems. Nowadays，AI 5.is being applied (apply) in many fields: finance, health care, natural language processing and art, to name but 6.a few. In short, this technology is transforming the way we live. While AI enthusiasts promise intelligent robots 7.will be working (work) to our advantage, these undoubted benefits also bring concerns and fears. As we become more and more 8.dependent (depend) on computers，9.warnings (warn) of the dangers posed by the advances in AI demand our attention. We need to be careful what we wish for and make sure we will not fall victim 10.to AI! 学科网（北京）股份有限公司 $$
