2、icial intelligence (AI).It goes beyond the expectation of its creators and escapes their control,eventually outcompeting and enslaving humans or targeting humans for extinction.Even in the real world,not everyone is ready to welcome AI with open arms.In recent years,as computer scientists have pushe

3、d the boundaries of what AI can accomplish,leading figures in technology and science have warned about the frightening dangers that artificial intelligence may pose to humans.But why are people so frightened about the idea of AI?Elon Musk is one of the famous voices that have raised red flags about

4、AI.In July 2017,Musk told attendees at a meeting of the National Governors Association,“I think people should be really concerned about AI.I keep sounding the alarm bell .But until people see robots going down the street and killing people,they dont know how to react,because the current influence do

5、esnt seem so overwhelming.” Physicist Stephen Hawking also expressed concerns about AI,once telling the BBC that the development of full artificial intelligence could spell the end of the human race.However,fears that AI will develop awareness and defeat humanity are grounded in misconceptions about

6、 what AI is,noted Weinberger,an associate professor.AI operates under very specific limitations defined by the algorithms (算法) that state its behavior.Some types of problems match AIs skill sets well,making certain tasks relatively easy for AI to complete.“But most things do not match them,and theyr

7、e not applicable,”Weinberger said.The other worrisome idea that a dishonest human would control AI for harmful actions is,unfortunately,far more likely,Weinberger added.Almost any type of machine or tool can be used for either good or bad purposes,depending on the users intent.But that misuse should

8、 not attribute to artificial intelligence.1.What is behind peoples joke about AI?A.Their fear for humans acceptance of AI.B.Their praise for AIs role in human development.C.Their pride in the achievements made in AI.D.Their concern about AIs threat to humans.2.The underlined word “overwhelming”in Pa

11、严重的。3.C推理判断题。根据第四段可知,人工智能的行为受算法的特别限制,所以有的问题人工智能是不能完成的。可见,Weinberger认为人工智能能力的边界是受到严格限制的。4.A观点态度题。根据倒数第二段的.fears that AI.are grounded in misconceptions about what AI is.以及最后一段The other worrisome idea.is.far more likely.可知,Weinberger既分析了AI战胜人类的错误观念,也表达了可能的担忧,所以他的态度是客观的。.七选五(2019湖北十堰高三模拟)Steps for a Suc
