10、n your notebook.2.Change your notebook with your shoulder partner and discuss three questions.Who is interviewed?What does the host ask?What is the experts opinion?Listen to the interview again and put these statements in the correct order.(P6 E2)49527386Audio ScriptWelcome back to the show.Just now

11、 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.Bu

12、t they often do simple tasks and do not look like humans,unlike in the movies.However,as artificial intelligence develops,well 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:Si

13、mon: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,t

14、oo.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?Audio ScriptHost:Simon:Host:v.(使）合并；成为一体Yes.Thats a good place to start.Asimov was one of the greatest sci-fi authors,and he wr

15、ote 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?Au

16、dio ScriptSimon: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

17、 that you dont have any robots at home?Simon:Well.yes,I do actually!Audio ScriptSimon:Host:Listen to the interview again and write down the discourse markers that you hear.Make a note of how each discourse marker is used in the interview.Then compare your answers with a partner.(P6 E3)Listen for dis

18、course markersDiscourse 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 allAnswer:1.What discour

22、ybe,apparently,sort of,kind of,perhaps,roughly,arguably,presumably.In groups,discuss what the expert thinks of the questions and exchange your own views.(P7 E4)1.What do you know about robot technology?What can robots do?2.What benefits do you think robots or AI will bring?Do you think they will cau

23、se problems as well?Discussion The logic behind the Three Laws of Robotics(conditions and results)Contradictions among these lawsAny more laws to be added3.Do you know anything about Isaac Asimov and his famous Three Laws of Robotics?What do you think of these laws?In groups,discuss what the expert

24、thinks of the questions and exchange your own views.(P7 E4)Discussion 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

25、 task according to computer programmes or through the use of some kind of controls.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 ca

26、n 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

27、 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

28、 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.Changing the topicMake a dialogue with your partners.You may use the following expressions t

29、o help you.EXAMPLEOh,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 thats beside the point.In my opinion,robots are dangerou

30、s!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.M

31、aybe,but thats 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 dev

32、ices that werent much different than some of the robots we have today.A:B:C:A:Sample dialogueSample dialogueYes,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.Lets see.there are simple repetitive tasks l

33、ike 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”?Wasnt it Isaac Asimov?He was that scientist who wrote a lot

34、of science fiction stories.B:C:A:C:B:Sample dialogueNo.the word robot was coined much earlier,I think.But thats 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 Asimovs writing was so important he created the Three Laws o

35、f Robotics.Law 1,robots cant 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 doesnt conflict with the first law;and Law 3,a robot must protect itself as long as the act of doing so doesnt break the first or second laws!A:C:A:But this is wh

36、ere 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 dont keep those rules?Sample dialogueB:C:HomeworkWrite a short passage about the advantages and disadvantages of AI.You can state your own opinions and put forward your own suggestions.THANK YOU
