What can robots do ?In groups,discuss what the expert thinks of the questions and exchange your own views.Activity4 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 can not do the work. However，they can cause problems,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.2.What benefit do you think robot or AI will bring? Do you think they will cause problems as well?In groups,discuss what the expert thinks of the questions and exchange your own views.Activity4 Yes,I do.Isaac Asimov introduced them into most of his science fiction writings to show that robots couldbe prevented from harming us or our world.They are not actual scientific laws， but rather guidelines for theirhuman programmers to follow to keep our world safe.At first glance，the rules seem logical and reasonable.3.Do you know anything about Isaac Asimov and his famous Three Laws of Robots?whatdo you think of these laws?In groups,discuss what the expert thinks of the questions and exchange your own views.Activity4 Oh，bytheway，.Oh，Iremember，.Inearlyforgot!.Thatremindsmeof.WhatImeanttotell/askyouis.，CouldIchangethesubject?but(perhaps)thatsbesidethepoint.Thenextitemontheagendais.Ithinkweoughttomoveonto.Oh，therewassomethingImeanttotellyou.Ontheonehand.Ontheotherhand.ChangingthetopicActivity4 Example: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 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.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 werent 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.Activity4C:I think we had better move on to what robots can do.Lets 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.B:Oh, there is something else I meant to ask youdoes anyone know who even came up with the word“robot”?C:But thats beside the point. I think we ought to move on to the benefits and dangers of A I to humans and our society.A:Oh, In early forgot why Asimovs writing was so importanthe createdthe Three Laws of Robotics. Law l,robots cant injure humans or allowthem to come to harm; Law 2, arobot must obey any order a humangives it as long as it doesnt conflict with the first law; and Law 3,a robotmust protect itself as long as the act of doing so doesnt break the first or second lawDotheexercisesonPage63ofWorkbook.
