UNIT 4　Living with technology 背话题金句，写高分文章 1．Mobile phones are everywhere，which sometimes can be very annoying. 到处都是手机，有时它们会很烦人。 2．It is universally acknowledged that sharenting is becoming more and more popular. 众所周知，网上“晒娃”越来越流行。 3．With the development of the Internet，shopping online is becoming more and more popular. 随着因特网的发展，网上购物越来越流行。 4．On arriving there，we set out to clean their houses，play games and teach them how to use apps on smartphones. 一到那里，我们就开始打扫他们的房子，玩游戏，并教他们如何使用智能手机上的应用程序。 5．There is no doubt that modern technology brings us convenience and comfort in life. 毫无疑问，现代科技给我们的生活带来方便和舒适。 单元话题导入 This Is What an AI-powered Future Looks Like A child born in the year 2030 will not understand why his or her parents once had to manually① turn on the lights in the living room.In the future, the smart home will know people's needs, wants and habits before they take any action. Amazon, Apple, Google and to some extent②Microsoft understand that the future of computing is voice input，powered③ by artificial④ intelligence (AI).Children of the future will grow up in a world powered by AI. The design of this child's world will be different from our world today，as the child will learn how to communicate with a machine by the time they're two years old. As a child's vocabulary grows into full sentences，their personal AI engine⑤will grow up with them. These children will grow up in a world of AI where they will interact with⑥everything using their voice. 单元话题导入 The popularity of the garage⑦in the United States started around 1925. Today, the necessity to design a garage for the smart home of the future is lessened as a majority⑧ of individuals⑨ will make use of⑩an autonomous vehicle⑪ brand⑫ instead of owning a vehicle. When you make use of a vehicle，95 percent of the time you will not need to garage the vehicle when it is not in use.The autonomous vehicle will drop you off at your front door. Upon entry⑬，the house will be set the way you prefer with lighting，temperature and music depending on the time of day you arrive. The AI that powers your smart home will understand the quirks⑭ that make you uniquely you and will ensure that the house operates in an efficient⑮manner. The home will always be listening and waiting for voice commands to complete tasks. When the home becomes a smart home and society is connected with AI, our habits and lives will change. Will you be ready for the change？ 单元话题导入 语篇导读： 　　人工智能在未来能为我们的生活提供极大的便利，改变我们生活的方方面面。 阅读助手： ①manually adv.手动地 ②extent n. 程度；限度；大小；范围 to... extent 到……程度；在……程度上 ③power vt. 以动力驱动，推动(机器或车辆)；(使)迅猛移动，快速前进 n. 电力供应；能量；力量；控制力 ④artificial adj. 人工的；人造的；假的 artificial intelligence (AI) 人工智能 ⑤engine n．引擎；发动机；火车头 ⑥interact with 与……互动 单元话题导入 ⑦garage n. 车库，停车房；汽车修理厂 vt. 将(汽车)开进/停放在车库 ⑧majority n. 大部分；大多数 ⑨individual adj.单独的；个别的 n. 个人 ⑩make use of 利用；使用 ⑪vehicle n. 交通工具；车辆 ⑫brand n. 品牌；类型；烙印 ⑬entry n．加入；进入；参与 ⑭quirk n. 怪癖 ⑮efficient adj. 效率高的；有功效的 Section Ⅰ　Welcome to the unit & Reading 内容索引 整体预习 1 语篇理解 2 课时精练 5 夯实双基 3 互动探究 4 整体预习 返回 ①option n．可选择的事物 ②press a button 按一下按钮 ③castle n. 城堡 ④given prep. 鉴于，考虑到 ⑤come true 实现 原文呈现 名师圈点 Artificial intelligence：friendly or frightening? 　　Imagine waking up one morning with the option① of staying in bed and pressing a button② to send a robot to do all the work for you.How cool that would be！【1】It may seem like building castles③ in the air，but given④ the rate at which artificial intelligence，or AI，is being developed，【2】in the future such dreams may actually come true⑤. 【1】画线部分为how引导的感叹句。 【2】画线部分为“介词＋关系代词”引导的定语从句，修饰先行词the rate。 ⑥input n. 输入的信息；投入 vt. 输入(信息) ⑦put forward 提出 ⑧capacity n. 领悟(或理解、办事)能力；容量，容积；职位，职责；生产量 ⑨analyse vt. 分析 ⑩massive adj. 巨大的，大而重的；非常严重的 ⑪multiple adj. 多个的，多种的 原文呈现 名师圈点 　　At the basic level，artificial intelligence is a branch of computer science that aims to create intelligent machines【3】．One of the essential aims of AI is to develop computer intelligence capable of learning from experience，adjusting to new inputs⑥ and performing tasks like humans.To achieve this aim，many approaches to creating true AI have been put forward⑦，including“deep learning”，which enables a machine to improve its own performance by learning from the results of its previous actions【4】．Deep-learning AI has the capacity⑧ to analyse⑨ massive⑩ amounts of data through multiple⑪ layers，imitating the complex networks of the human brain. 【3】画线部分为that引导的定语从句，修饰先行词a branch。 【4】画线部分为which引导的非限制性定语从句，修饰先行词deep learning。 ⑫coin vt. 创造(新词语) ⑬pioneer n. 拓荒者；先锋vt. 做先锋，倡导；开辟(道路) ⑭in the field of 在……领域 ⑮breakthrough n. 重大进展，突破adj. 突破性的 ⑯arguably adv. 可论证地，按理 ⑰demonstrate vt. 证明；示范，演示；表露 原文呈现 名师圈点 　　The dream of AI has been around for centuries，and 【5】 the development of computers since the 1940s has finally made it a reality.

It is clear that we are at a turning point㉓ in history.【7】With machines like AlphaGo now capable of thinking and learning from their mistakes，we are getting closer to the dividing line between humans and machines.The question is，where will all this lead？While AI enthusiasts promise us a bright future where intelligent robots will be working to our advantage㉔，these undoubted benefits also bring concerns and fears.【8】Could machines really develop human-like intelligence？And what would happen if they did? Would thinking machines work alongside humans or threaten㉕ the existence of humans？How would they be punished if they committed crimes㉖ or even murdered humans？As we become more and more dependent on computers，some scientists are urging㉗ us to think about the dangers posed㉘ by the advances in AI. Stephen Hawking，for example，warned，“The development of full artificial intelligence could spell the end of the human race.” 【7】it作形式主语，that引导真正的主语从句。 【8】while引导让步状语从句，意为“虽然，但是”；where引导定语从句，修饰先行词a bright future。 ㉙apparently adv.显然，可见 ㉚warning n. 警告，先兆；警戒 ㉛victim n. 受害者，牺牲品；受骗者；祭品 fall victim to 受伤，受损，被害 原文呈现 名师圈点 　　Apparently㉙，such warnings㉚ demand our attention. We need to make sure that we will not fall victim㉛ to AI.We may still think it would be fantastic to relax all day and allow autonomous machines to do all the work for us－but perhaps we should not be too greedy and rather be careful what we wish for! 译文参考 人工智能：是敌是友？ 想象一下，某天早上你醒来，可以选择继续躺在床上，按下一个按钮，就能招来一台机器人为你处理所有的工作，那该有多酷啊！这听起来可能像是在建空中楼阁，但鉴于人工智能(AI)目前的发展速度，这样的梦想在将来也许真的可以实现。 从基础层面上讲，人工智能是计算机科学的一个分支学科，其目标是研发智能机器。AI的基本目标之一是开发能够学习过往经验，适应新的输入内容并且能够像人类一样执行任务的计算机智能。为了实现这个目标，人们提出过许多创造真正的AI的方法，其中包括“深度学习”——这种方法可以让机器通过学习自己先前的行为结果，来提升自身性能。深度学习AI拥有从多个层次分析海量信息的能力，它模拟的是人脑的复杂网络结构。 AI的梦想已经存在了几个世纪，而20世纪40年代以来计算机的发展，终于让这个梦想成为现实。“人工智能”这个术语是在20世纪50年代中期被创造出来的，而在好几年前，这一理论就被计算机科学领域的先驱之一艾伦·图灵探索过。然而在很长一段时间里，AI技术发展得相当缓慢。1997年，AI发展有了一个重大突破，当时一台名叫深蓝的国际象棋计算机打败了国际象棋世界冠军加里·卡斯帕罗夫。之后在2017年，一个叫阿尔法围棋的计算机程序下赢了可谓人类最强的围棋棋手柯洁，这说明了深度学习AI系统的一大显著进展。 如今，AI已经应用于许多领域，如金融、医疗保健、机器翻译和艺术等，不一而足。从自动驾驶车辆到家用机器人，从推荐系统到撰写小说的电脑，AI有着不计其数的应用。普通人现在能够使用AI获取外语文本的即时翻译，机器也已经能够识别人们的指纹甚至面容。 简而言之，这项技术正在改变我们的生活方式。显然，我们正处于历史的转折点。有了阿尔法围棋这种能够思考并从自身错误中学习的机器，我们正在向人类与机器的界限越靠越近。问题在于，这一切将会导致什么？AI的热烈支持者向我们承诺未来会是美好的，到那时智能机器人将为人类谋利；但这些毋庸置疑的好处也带来了忧虑和恐惧。机器真的能够发展出像人类一样的智能吗？如果真的可以，又会发生什么？能够思考的机器是会与人类并肩工作，还是会威胁人类的生存？如果它们犯了罪甚至谋杀了人类，又该如何惩罚？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进步所带来的危险。例如，斯蒂芬·霍金就曾警告说：“完全人工智能的发展可能意味着人类的终结。” 　　显然，这样的警告需要得到我们的重视。我们需要确保自己不会沦为AI的受害者。我们可能还是会认为，可以整天放松，让自动化机器为我们完成所有工作，这样的生活很美妙——但也许我们不该太过贪婪，而应对我们的期待保持谨慎！ 返回 语篇理解 返回 第一步　文本整体理解：理清文章架构 1．What does the text mainly talk about?

Repurposing drugs is legal and not unusual. When doctors prescribe(开处方)drugs that have been approved by the Food and Drug Administration (FDA)for purposes different from what is printed on the labels，the drugs are being used “off-label”. Just because a drug is FDA-approved for a specific type of disease does not prevent it from having possible benefits for other purposes. For example，Metformin，a drug that is FDA-approved for treating type 2 diabetes，is also used to treat PCOS(a disease of women)，and other diseases. Trazodone，an anti-depressant with FDA-approval to treat depression，is also prescribed by doctors to help treat patients with sleep issues. The Ohio State University research team created an AI deep learning model for predicting treatment probability with patient data including the treatment，outcomes，and potential confounders(干扰因素). Confounders are related to the exposure and outcome.For example，a connection is identified between music festivals and increases in skin rashes(红疹). Music festivals do not directly cause skin rashes. In this case，one possible confounding factor between the two may be outdoor heat，as music festivals tend to run outdoors when the temperature is high，and heat is a known cause for rashes. When working with real-world data，confounders could number in the thousands. AI deep learning is well-suited to find patterns in the complexity of potentially thousands of confounders. 　　The researcher team used confounders including population data and co-prescribed drugs. With this proof-of-concept，now clinicians have a powerful AI tool to rapidly discover new treatments by repurposing existing medications. 语篇解读　本文是一篇说明文。文章主要介绍了在《自然机器智能》杂志上发表的一项研究中，俄亥俄州立大学的研究人员展示了人工智能(AI)如何能够跟踪临床试验，识别药物标示外的用途，这一解决方案有助于推动创新治疗。 1．What do we know about a drug used off-label? A．It is sold without a label. B．It is available at a low price. C．Its uses extend beyond the original ones. D．Its clinical trials are rejected by doctors. 推理判断题。根据文章第二段“When doctors prescribe drugs... from having possible benefits for other purposes.”可知，“标示外”药物的用途超出了原来的用途。故选C。 √ 2. Metformin and Trazodone are similar as both of them____________． A．are used off-label B．treat rare diseases C．result in sleep issues D．are medical breakthroughs 细节理解题。根据文章第二段“the drugs are being used... having possible benefits for other purposes.”和文章第三段“For example，Metformin，...help treat patients with sleep issues.”可知，二甲双胍和曲唑酮的相似之处是这两种药物都在适应症外使用。 故选A。 √ 3．What can be inferred about “confounders”？ A．They are possible treatments. B．They are environmental factors. C．They can be easily recognized in real-world data. D．They should be taken into serious consideration. 推理判断题。根据文章第五段的“When working with real-world data，...of potentially thousands of confounders.”可知，干扰因素应该被认真地考虑。故选D。 √ 4．What is the main idea of the text? A．AI examines benefits of existing drugs. B．AI identifies off-label uses for drugs. C．AI finds new drugs for common diseases. D．AI proves the power of drug research. 主旨大意题。根据文章第一段“In a study published in Nature Machine Intelligence，...can help advance innovative treatments.”再结合下文内容可知，文章主要讲述人工智能识别药物标示外用途。故选B。 √ B Technology is supposed to make our lives easier，allowing us to do things more quickly and efficiently. But too often it seems to make things harder. This increase in complexity，often called “feature creep，” costs consumers time，but it also costs business money. Product returns in the U．S. cost a hundred billion dollars a year，and a recent study by Elke den Ouden，of Philips Electronics，found that at least half of returned products have nothing wrong with them. Consumers just couldn't figure out how to use them. Companies now know a great deal about problems of usability and consumer behavior，so why is it that feature creep proves unstoppable? In part，feature creep is the product of the so-called internal-audience problem: the people who design and sell product are not the ones who buy and use them，and what engineers and marketers think is important is not necessarily what's best for consumers. The engineers tend not to notice when more options make a product less usable.And marketing and sales departments see each additional feature as a new selling point，and a new way to attract customers. You might think，then，that companies could avoid feature creep by just paying attention to what customers really want. But that's where the trouble begins，because although consumers find overloaded gadgets( 配件)unmanageable，they also find them attractive.It turns out that when we look at a new product in a store we tend to think that the more features there are，the better. It is only once we get the product home and try to use it that we realize the virtues of simplicity. 　　It seems strange that we don't expect feature tiredness and thus avoid it. But，as numerous studies have shown，people are not，in general，good at predicting what will make them happy in the future.As a result，we will pay more for more features because we systematically overestimate how often we'll use them. We also overestimate our ability to figure out how a complicated product works. 　　The fact that buyers want bells and whistles but users want something clear and simple creates an unusual problem for companies. A product that doesn't have enough features may fail to catch our eye in the store.But a product with too many features is likely to annoy consumers. 语篇解读　本文是一篇说明文。文章主要介绍了科技的“功能蔓延”是不可阻挡的，拒绝“功能蔓延”不是一件容易的事情。 5．What does the first paragraph mainly discuss? A．The benefits brought by the advanced technology. B．The recent study conducted by Elke den Ouden. C．The loss caused by the feature creep of technology. D．Many problems of usability known by the consumers. 段落大意题。根据第一段内容，特别是“This increase in complexity，often called ‘feature creep，’ costs consumers time，but it also costs business money.”可知，本段主要讲的是技术的“功能蔓延”造成的损失，故C项正确。 √ 6．Which of the following is TRUE according to the second paragraph? A．It is the audience problem that leads to feature creep. B．What matters to designers and marketers is not good for consumers. C．Feature creep brings blessings to the people in marketing and sales. D．The engineers will not pay attention to the quality of the product. 细节理解题。根据第二段中的“And marketing and sales departments see each additional feature as a new selling point，and a new way to attract customers.”可知，“功能蔓延”给营销和销售人员带来福音，故C项正确。 √ 7．What do we know about the buyers in Paragraph 4? A．They are deeply convinced that all the products work in simple way. B．They are fed up with the more and more features of the products. C．They are too confident of their ability to use the complicated products. D．They are quite clear about the products which will make them happy. 细节理解题。根据第四段中的“We also overestimate our ability to figure out how a complicated product works.”可知，购买者高估了自己理解复杂产品工作原理的能力，也就是说他们对自己使用复杂产品的能力过于自信，故C项正确。 √ 8．What can be a suitable title for the text? A．Saying No to Feature Creep is No Easy Thing B．Feature-heavy Products in Demand C．The More Features，the Better D．Simplicity Outweighs Complexity 标题归纳题。通读全文，特别是根据第一段中的“so why is it that feature creep proves unstoppable？”可知，本文从设计者和消费者的角度介绍了科技的“功能蔓延”是不可阻挡的，拒绝“功能蔓延”不是一件容易的事情，故A项正确。 √ Ⅱ.阅读七选五(每小题2.5分，共12.5分) 　　Robots have been taking our jobs since the 1960s.
