Lead-in ： What kinds of robots or AI developments do you hope for? Two robots are serving food at a café. A robot is playing the piano. A robotic arm works at a factory. A robot band is performing. Several robots are playing soccer. Possible answer: I hope for an educating robot because I can ask any questions when I have troubles in learning. What are the pros and cons of robots doing these jobs ? A robot is playing the piano. Pros: Cons: The robot can play anything perfectly. No creativity or emotion involved. A robot band is performing. Pros: Cons: More live music will be available more cheaply; Playlists will be limitless. It really isn't live music; It is more like listening to a record, without any of the excitement and emotion of watching humans perform. What are the pros and cons of robots doing these jobs ? A robotic arm works at a factory. Pros: Cons: Simple, repetitive tasks are done at higher speeds more cheaply and accurately. Humans end up out of work; No added skill or creativity. Several robots are playing soccer. Pros: Cons: Promote learning and enjoyment of AI and robotics to a wider audience. They don't even know they are in a contest and have no desire to win or lose, so there is no emotional content to match; no talent involved. What kinds of robots or AI developments do you hope for? I hope for an educating robot because I can ask any questions when I have troubles in learning. Listening and Speaking： Listen to an interview and complete the questions as follows. What are the key aspects mentioned in the interview? Write down the key information on your notebook. Change your notebook with your shoulder partner and discuss three questions. Who is interviewed? What does the host ask? What is the expert’s opinion? Listen and put these statements in the correct order. 4 9 5 2 7 3 8 6 Welcome back to the show. Just now we talked about time travel with sci-fi expert, Simon Phoenix. So, if we could move on now, Simon, robots are often in the news these days. Do you think robots will eventually live among us, and do most of our jobs for us, like in science fiction? Well, robots already do many jobs, in factories, for example. But they often do simple tasks and do not look like humans, unlike in the movies. However, as artificial intelligence develops, we’ll certainly see robots with more complex occupations, such as teaching or nursing, and we are therefore likely to make them look more like us, so we feel more comfortable. Host: Simon: What benefits and problems do you think this would bring? The main benefit would be greater labour efficiency, giving us more time for other things. But there would certainly be issues with integrating them into society. The more intelligent they become, the more powerful and dangerous they will be, too. Above all, we need to think carefully about how to programme them to protect us humans. That reminds me of the Three Laws of Robotics by Isaac Asimov. Is that what you mean? Host: Simon: Host: v.(使）合并；成为一体 Yes. That’s a good place to start. Asimov was one of the greatest sci-fi authors, and he wrote the Laws in 1942. However, he also showed how the Laws could be broken. I believe he was showing us the problems we would have with such intelligent machines. In sci-fi stories, robots often become superior and take over. Do you think this could really happen? If so, should we not build clever robots? Simon: Host: It is very hard to stop technology once it has been created. Robot technology is developing very fast, so it could be possible. We use technology more and more in our lives. I think the line between humans and robots will be more blurred in the future. Thanks a lot, Simon. So, I take it that you don’t have any robots at home? Simon: Well ... yes, I do actually! Simon: Host: Write down the discourse markers that you hear. Listen for discourse markers Discourse markers are used to organise a text by marking sequence, contrast, opinion, purpose, and soon. Listening for discourse markers can help you understand a text more easily. For example, first, however, above all, in order to, etc. just now; so; well; but; however; above all Answer: What discourse markers do you often use? What are their functions? Thinking Time Function Discourse markers to start or end conversations to change topics to order or sequence to show interest / surprise / sympathy now, so, right, in general, to sum up, for a start, ... what’s more, well, but, however, anyway, ... first (of all), above all, next, ... sure, good, quite, wonderful, exactly, absolutely, certainly, definitely, I see, (all) right, That’s great / interesting / amazing / awful ... Function Discourse markers to rephrase or change what we say well, in other words, the thing is, I mean, you know what I mean, what I mean is ... to mark the old, shared, or expected knowledge and new knowledge just now, you know, see, you see, the thing is ... to mark attitude or point of view in speaking or writing honestly, basically, predictably, no doubt, to tell you the truth, I think, I’m afraid, of course I must admit, if you ask me, I must say ... not to sound too direct or forceful like, just, maybe, apparently, sort of, kind of, perhaps, roughly, arguably, presumably ... Discussion： What the expert thinks of the questions and exchange your own views. What do you know about robot technology? What can robots do? What benefits do you think robots or AI will bring? Do you think they will cause problems as well? What do you know about robot technology? What can robots do? Robots technology has its cons and pros. It can bring great convenience to human beings together with some scientific or moral problems. A robot is a machine that can do a task according to computer programmes or through the use of some kind of controls. What benefits do you think robots or AI will bring? Do you think they will cause problems as well? The main benefits are that they can do some kinds of work more quickly, better, and cheaper than humans, and that they can take the place of humans when no humans are available or when humans cannot do the work. They can cause problems, however. First, what happens if they no longer serve people or stop following orders? Second, there is the possibility that at some point we will have difficulty determining what constitutes a living being and what constitutes a machine. Do you know anything about Isaac Asimov and his famous Three Laws of Robotics? What do you think of these laws? Yes, I do. Isaac Asimov introduced them into most of his science fiction writings to show that robots could be prevented from harming us or our world. 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, but they also seem outdated. Make a dialogue： What the expert thinks of the questions and exchange your own views. Changing the topic Oh,by the way,... Oh, I remember, ... I nearly forgot!... What I meant to tell/ask you is ... ..., but (perhaps) that's beside the point. That reminds me of ... The next item on the agenda is... I think we ought to move on to... On the one hand...On the other hand... Oh,there was something I meant to tell you. Could I change the subject? Changing the topic EXAMPLE Oh, by the way, I saw a programme about robot doctors last night. It was very interesting. Do you think robots will do more of these important jobs in the future? Certainly. They will probably do most of our labour for us. Maybe, but that’s beside the point. In my opinion, robots are dangerous! They are much stronger than we are and may be superior to us in the future. A: B: C: Oh, by the way, I saw a programme about robot doctors last night. It was very interesting. Do you think robots will do more of these important jobs in the future? Certainly. They will probably do most of our labour for us. Maybe, but that’s beside the point. In my opinion, robots are dangerous! They are much stronger than we are and may be superior to us in the future. I think we ought to move on to the topic of robot technology. I know the idea of it has been around forever. The ancient Greeks and Chinese both made clever devices that weren’t much different than some of the robots we have today. A: B: C: A: Sample dialogue Sample dialogue Yes, but the modern idea of intelligent robots that look like humans is only about 100 years old. I think we had better move on to what robots can do. Let’s see ... there are simple repetitive tasks like factory work and housework. Yes, and I think there will be more complex jobs in the future like in healthcare, education, or entertainment. Oh, there is something else I meant to ask you — does anyone know who even came up with the word “robot”? Wasn’t it Isaac Asimov? He was that scientist who wrote a lot of science fiction stories. B: C: A: C: B: Sample dialogue No ... the word robot was coined much earlier, I think. But that’s beside the point. I think we ought to move on to the benefits and dangers of AI to humans and our society ... Oh, I nearly forgot why Asimov’s writing was so important — he created the Three Laws of Robotics. Law 1, robots can’t injure humans or allow them to come to harm; Law 2, a robot must obey any order a human gives it as long as it doesn’t conflict with the first law; and Law 3, a robot must protect itself as long as the act of doing so doesn’t break the first or second laws! A: C: A: But this is where the real danger lies. Those laws are not real laws — they are guidelines that hopefully humans remember when they programme the robots. How can we trust our safety if the robots are programmed by people who don’t keep those rules? … Sample dialogue B: C: 仓颉之初作书盖依类象形故谓之文其形声相益即谓之字文者物象之本字者言孳乳而浸多也著于竹帛谓之仓颉之初作书盖依类象形故谓之文其形声相益即谓之字文者物象之本字者言孳乳而 Using Language - Listening 新人教选必四 Unit 1 Thank You ! $$
