Fast-reading 1 Read the passage quickly and answer questions. 1. What is the text mainly about? A. Self-driving cars. B. The biggest threat. C. Three views on AI. D. The greatest human achievement. 2. Where does the passage probably come form? A. Newspaper B. Online forum C. Magazine D. Research paper In the words of (用......的话来说，根据......的说法）Professor Stephen Hawking, artificial intelligence will be “either the best, or the worst thing, ever to happen to humanity”. Technology of Tomorrow Forum wants to hear your thoughts on AI. Is it our greatest human achievement so far? Or is it the biggest threat to our existence? What’s the function of the words of Stephen Hawking? A．To give the background. B．To put forward/raise the question. C．To introduce the topic. D．To express the purpose. √ Is AI our biggest achievement or threat? Let’s go on reading with this question. Activity 2: Careful-reading for details sth happen to sb 某事发生在某人身上 1 Thanks to Al, I've got my own supersmart personal assistant built （植入）into my phone. She always has an immediate answer for any question I put （提问）to her, and even uses my answers to learn more about my preferences（偏好）. It used to feel like 50 per cent of my time was spent researching new restaurants. In contrast（相反地）, my PA only needs a few seconds to find the right place. Every recommendation she gives me is great since/as/because she can predict if I will like a particular(特定的） restaurant. in contrast = by contrast 相反地 recommendationv.recommend 推荐 2 And speaking of (说到) hanging out(闲逛), I'm hoping that self-driving cars (自动驾驶汽车) are available(可获得的，可利用的) soon. I've been taking driving lessons for over a year, and still haven't got my licence(执照，许可证). Self-driving cars can learn to drive in the same way that we do, and can make judgements based on information. And as/since/because they won’t be susceptible to(=be influenced by) human error, they'll certainly be a lot safer. The only thing is that there might be a few machine-learning problems when the first cars hit the market, so perhaps I’d better learn to drive first. Still, I do think that developments in Al will on the whole make doing day-to-day things a lot easier. hit 到达，进入（市场） on the whole 总体而言 day-to-day 日常的，例行的 hit 各项词义拓展 1. The boxer hit his opponent hard in the face. 2. The car hit a tree on the side of the road. 3. We hit the city at dusk. 4. A hurricane hit the coastal area last week. 5. It hit her that she had made a big mistake. 袭击 碰撞 到达 突然想到 打击，击中 1. Find details about Millenniumbutterfly’s views： Read Paras. 1-2 and do the following exercises. • getting my own __________________________ • When researching new restaurants: super-smart personal assistant before:_______________________ now:_____________________ 50% of my time was spent a few seconds AI can _________ save time • hoping that self-driving cars are available soon. Why? ① Self-driving cars can learn to drive in the same way that human do, and can make judgements based on information. ②They won’t be susceptible to human error. AI can make driving ______ safer AI can make _______________________ easier doing day-to-day things achievement 2.What rhetorical device/figure of speech does the author use in this sentence? A．Metaphor(隐喻)． B．Personification． C．Hyperbole(夸张)． D．Antithesis(对比)． Every recommendation she gives me is great since she can predict if I will like a particular restaurant. √ 3. What’s Millenniumbutterfly’s attitude to AI? A．Negative. B．Critical. C．Objective. D．Positive. √ 1.approving 2.optimistic 3.favourable be capable of 能够 capability n. 能力 keep around 将……保留身边 wipe out 清除干净 3 The technology you're using and enjoying today is a basic form of Al which can’t think independently without programming编辑程序. Of course, it could be very useful to have a more advanced form of Al-a truly independent form of artificial intelligence, capable of exercising(运用，行使某种能力) its own judgement, could help us solve many of the world's problems. But have you ever thought about the risks? After all, why would an independent form of Al need to consider the opinions and desires of humans? We could be seen as a"small"inconvenience that’s in the way of a solution to a bigger problem. If we’re lucky, Al might think we’re valuable enough to keep around. If not, it might wipe us all out! 4 Even if that doesn't happen, there are other risks. Millenniumbutterfly, you say how great it would be to have self-driving cars, but what about all the taxi drivers who would lose their jobs? They would just be among the first victims of Al.Nearly every job is potentially at risk in the long run. Even journalists are now being replaced with technology that can write basic news reports. As it is（事实上，实际上）, almost 50 per cent of US jobs are at risk from automation in the next 20 years. 5 The truth is that none of us is prepared for the challenges of Al. Read Paras. 3-5 and do the following exercises. 1. Find details about Popkid’s views： • It might ________________________. wipe all human beings out • Nearly every job ________________________. is at risk in the long run • Conclusion: ___________________________________________. We’re not prepared for the challenges of AI threat 2.What’s Popkid’s attitude to AI? A．Negative. B．Critical. C．Objective. D．Positive. √ 1pessimistic 2.disapproving 3.doubtful 4.indifferent 5.unconcerned 3. Which one is right according to Popkid’s opinion on AI? A．People have been prepared for the risks AI will bring. B．AI will offer more jobs to people. C．People should not ignore the risks brought by AI. D．Risks outweigh(超过,比......更重要） benefits of AI. √ 6 Machine learning is something we have come to accept as a part of our modern world. I believe most of the value of AI lies in its capacity to analyse and interpret vast（大量的） amounts of data, which means it can even solve problems that are too challenging for human experts. 7 But while/although super-intelligent Al could be the biggest leap(巨变，飞跃) forward in human history, if it goes wrong or falls into the wrong hands,it could also be the most dangerous. However, Al is not going to go away/disappear. We have no choice but to embrace(v.欣然接受，拥抱) it and regulate(控制、管理) it. One thing I think we all agree on(认可), though, is that saying"My Al did it！” won't be any excuse for illegal or immoral behaviour! fall into the wrong hands: 落入不当之人手中 Read Paras. 6-7 and do the following exercises. 1. Find details about Pink-haze’s views： • Advantage: AI can ________________________________________________. • Disadvantage: AI could be _________________________________________. • Solution: ________________________________. solve problems that are too challenging for human experts the most dangerous if it falls into the wrong hands We should embrace and regulate it 2. The opinion of Pink_haze is ________. A．subjective B．objective C．indifferent D．negative √ 3. For AI, what does Pink haze agree with? A．It is easy to fall into the wrong hands. B．We should control it while making good use of it. C．In modern society, mankind can neglect /ignore AI’s disadvantages. D．People can use other high technologies to replace AI. √ We all need to learn to live with AI technology whether we like it or are concerned about it. We cannot stop the march of progress. I admit that more advanced AI could be helpful in solving the world’s problems, but there is a high level of risk involved. I can’t understand why some people worry so much. I hope more breakthroughs in AI will be made soon, so that we can enjoy more and more convenience. While-reading Activity1: Match the opinions with the persons. 2.
