Unit 1 Period 4 Using Language(1) （课件）-【步步高】2023-2024学年高二英语选择性必修第四册（人教版2019）

Unit 1 Science fiction Period 4 Using Language(1)—Listening and Speaking By the end of this period, you will be able to: 1. learn the information about robots; 2. predict what you will hear before you listen; 3. voice your opinions on robots and AI; 4. organise a text by using discourse markers； 5. exchange your own views with others. 2 1. What are these robots doing? 2. What are the pros and cons of robots doing these jobs? Pre-Listening Pros: May be cheaper and faster Cons: Communication difficulties No human touch Pros: Can play anything perfectly Cons: No creativity or emotion involved Pros: More live music will be available more cheaply. Playlists will be limitless. Cons: 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. Pros: Simple, repetitive tasks are done at higher speeds more cheaply and accurately. Cons: Humans end up out of work No added skill or creativity Pros: Promotes learning and enjoyment of AI and robotics to a wider audience Cons: The robot players don’t even know they are in a contest and have no desire to win or lose, so there is no emotional content to the match. No physical skill or talent is involved either. 3. What kinds of robots or AI developments do you hope for? e.g.: I hope for an educating robot because I can ask any questions when I have troubles in learning. Task 1 Listen to the interview and complete the questions that the host asks. 1. Do you think robots will eventually ____________, and __________________ for us…? 2. What ___________________ do you think this would bring? 3. That reminds me of the ____________________ by Isaac Asimov. Is that _______________? 4. In sci-fi stories, robots often become _______ and __________. Do you think this could really happen? If so, should we not ________________? 5. So, I take it that you don’t ______________________? live among us do most of our jobs benefits and problems Three Laws of Robotics what you mean superior take over build clever robots have any robots at home While-Listening Task 2 Listen again and put these statements in the correct order. 1 The host introduces the guest, a sci-fi expert. ___ The expert has robots in his home. ___ As robots become more intelligent, they may also become more dangerous. ___ The host mentions Asimov’s Three Laws of Robotics. ___ The expert says robots will have occupations such as teaching and nursing. ___ The line between humans and robots will be more blurred in the future. ___ The host asks about benefits and problems. ___ The host asks if there are robots in the expert’s home. ___ In sci-fi stories, robots often become superior and take over. 9 4 5 2 7 3 8 6 Task 3 Listen to the interview again and fill in the blanks with the discourse markers that you hear.

Listening text Host: 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? Simon: 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: What benefits and problems do you think this would bring? Simon: 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. Host: That reminds me of the Three Laws of Robotics by Isaac Asimov. Is that what you mean? Simon: 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. Host: 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: 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. Host: Thanks a lot, Simon, So, I take it that you don't have any robots at home? Simon: Well... yes, I do actually! Work in pairs Discuss what the expert thinks of the questions and exchange your own views. 1. 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. Post-Listening 2. 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. 3. 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. 常见话题句式：Changing the topic Oh, by the way... Oh, I remember... I nearly forgot!... What I meant to tell/ask you is... That reminds me of... I think we ought to move on to... Oh, there was something I meant to tell you. ..., but perhaps that is beside the point. The next item on the agenda is... On the one hand...On the other hand... Could I change the subject？ Example: go on with the conversation A: 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? B: Certainly. They will probably do most of our labour for us. C: 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: 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. B: Yes, but the modern idea of intelligent robots that look like humans is only about 100 years old. C: I think we had better move onto what robots can do. Let's see...there are simple repetitive tasks like factory work and housework. A: Yes, and I think there will be more complex jobs in the future like in healthcare, education, or entertainment. C: Oh, there is something else I meant to ask you—does anyone know who even came up with the word “robot”？ B: Wasn’t it Isaac Asimov? He was that scientist who wrote a lot of science fiction stories. A: No...the word robot was coined much earlier, I think. C: But that’s beside the point. I think we ought to move onto the benefits and dangers of AI to humans and our society… A: 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! B: 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? C: ... Finish the exercise that is given today.

Welcome back to the show. Just now we talked about time travel with size, I 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 art official intelligence develops, we'll certainly see robots with more complex, such as teaching or nursing, and we are therefore likely to make them look more like us, so we feel more comfortable. 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 issued 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 program them to protect us humans. That reminds me of the three laws of robotics by iie. Oh, is that what you mean? Yes, that's a good place to start. Asimov was one of the greatest size I authors, and he wrote the laws in one thousand nine hundred and forty two. 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 side, side stories. Robots often be come superior and take over. Do you think this could really happen? If so, should we not build clever robots? 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. Well, yes, I do actually.
