5、t to identify ourselves and pay for items.Our hands could even be used to exchange digital business cards or any other information through a handshake.1.Have you heard about artificial intelligence?What do you know about it?I know that we already use AI in our daily lives.Some cars use AI for naviga

6、tion and to enhance self-driving capabilities.Pre-readingI heard that the robot can serve customers in the restaurant.Besides,it enables parents to monitor their childrens activities and behavior.2.According to the title and pictures,what could be discussed in this article?Artificial Intelligence:fr

7、iendly or frightening?main topictwo aspectsIn my opinion,the title uses the words“friendly”and“frightening”,which indicates that this article might touch upon the benefits and threats of AI.The four pictures on the next page suggest a possible discussion of the various relationships between AI and h

11、usiasts promise us a bright future where intelligent robots will be working to our advantage,these undoubted benefits also bring concerns and fears.6.Read the title of the science article again.(1)Do you think“friendly”and“frightening”are perfectly used in the title?Why?I think so.“Friendly”and“frig

12、htening”are two opposite aspects,which form a sharp contrast.Besides,the title adopts alliteration,and“friendly”and“frightening”make the title more vivid.Alliteration(押头韵)is a figure of speech,which is good for sound rhyme,musical effect and significant emphasis.It is used widely,not only in poetry,

13、proverbs(谚语)and idioms(习语),but also in journalism,especially in the title of a book and headline of news and advertising.eg.safe and sound Pride and Prejudice 傲慢与偏见Beauty and the Beast 美女与野兽(2)The title is in the form of a question.Whats the function?In the form of a question,the author tries to aro

20、on Garry Kasparov.A computer program named AlphaGo defeated Ke Jie,arguably the best human Go player.AI is already being applied in many fields.People can use AI to help them drive vehicles,write novels,translate foreign languages and do many other things.From this points of view,AI can be friends w

23、 our advantage.CAutonomous machines can do much work for us.DWe are getting closer to the dividing line between humans and machines.Para.53.How does the author express the worries about the AI technology?A.By asking questions.B.By making comparison.C.By having a discussion.D.By referring to document

24、s.(1)Thinking machines could threaten the existence of humans.(2)How would they be punished if they committed crimes or even murdered humans?(3)As we become more and more dependent on computers,some scientists are urging us to think about the dangers posed by the advances in AI.4.Why could the devel

25、opment of AI be frightening？5.What did Stephen Hawking mean by saying“The development of full artificial intelligence could spell the end of the human race.”?APeople should be forbidden from using AI.BPeople should be aware of the possible dangers of AI.CAI will kill all human beings in the future.D

26、AI will bring a bright future to human beings.6.Why does the author quote the words by Stephen Hawking?ATo show the author likes Stephen Hawking very much.BTo show the authors attitude.CTo inform readers of the good saying.DTo make the opinion more convincing.1.What can we do when faced with such wa

27、rnings?(L47-48)We need to make sure that we will not fall victim to AI.(L50-51)we should not be too greedy and rather be careful what we wish for!2.Why does the author refer to the robot(autonomous machine)again in the last paragraph?The author brings the topic back to the dream of AI at the end of

28、the article,which echoes what he says at the beginning.This makes readers think deeper about the question in the title.Para.63.What are the similarities and differences between the content of the first and the last paragraphs?Why are they different?(2)Difference:After explaining the potential danger

29、s posed by AI,the author warns us not to be too greedy about this fantasy in the last paragraph.(1)Similarity:Both paragraphs mention an imaginary scene of a robot helping people to do all the work.(3)The change of attitudes between the two paragraphs indicates that we should be critical about the f

30、uture development of AI.Post-reading1.In Lines 44-46,Stephen Hawking is quoted as saying,“The development of full artificial intelligence could spell the end of the human race.”Do you agree with him?why or why not?(Critical thinking)2.What do you think intelligent machines will be capable of doing i

31、n the future?(Creative thinking)1.In Lines 44-46,Stephen Hawking is quoted as saying,“The development of full artificial intelligence could spell the end of the human race.”Do you agree with him?why or why not?(Critical thinking)(1)Yes,I agree with Stephen Hawking.With the development of full artifi

32、cial intelligence,machines may become so intelligent that human beings could no longer control them.If super-intelligent AI machines could think and act completely on their own,it remains to be seen how they would treat human beings.It would be extremely dangerous if they decide that humans are thei

33、r enemies.(2)No,I do not agree with Stephen Hawking.I think that scientists fully understand the concerns about AI,and they will surely be careful about developing it.Even if we are able to create true artificial intelligence,we will know how to control it.2.A mini sharing session(分享会分享会)will be hel

35、 we have a medical problem and if we need to go to hospital.It might even take the place of the human doctor and treat us at home or in hospital.(2)I think an AI machine will look after our homes for us:it will be able to tell when we are running low on food or cleaning products,and order them for u

36、s based on what we usually get.(3)It might also be able to read our digital calendars and order things like plane tickets and taxis based on where we need to go.AI is a two-edged sword,so we couldnt just focus on the benefits it brings to us.Not be too greedy and rather be careful what we wish for!L
