10、.A computer program AlphaGo defeated arguably the best human Go player.Alan Turing had explored the theory of AI.Detailed reading(Para.3)The development of AI coin n.v.【词源词源】coin本义是铸造硬币的模本义是铸造硬币的模具，来自拉丁语具，来自拉丁语cuneus（楔子）。（楔子）。因古罗马时期用来冲压硬币的模子因古罗马时期用来冲压硬币的模子形状是楔形的而得名。所以，由此形状是楔形的而得名。所以，由此衍生出衍生出“铸造、创造、杜

13、efits of AI also bring concerns and fears.Could machines really develop human-like intelligence?And what would happen if they did?Would thinking machines work alongside humans or threaten the existence of humans?How would they be punished if they committed crimes or even murdered humans?As we become

14、 more and more dependent on computers,we should think about the dangers posed by the advances in AI.Therefore,the development of AI could also be frightening.Artificial intelligenceWhat is the authors attitude to artificial intelligence?A.supportive B.doubtful C.Objective D.indifferent He thinks AI

15、can bring us benefits and maybe some negative effects as well.Critical thinking“完全人工智能的发展可能意味着人类的终结。完全人工智能的发展可能意味着人类的终结。”spell v.招致，意味着（通常指坏事）招致，意味着（通常指坏事）,“The development of full artificial intelligence could spell the end of the human race.”Do you agree with him?Why or why not?DiscussionOption 1Y

16、es,I agree with Stephen Hawking.With the development of full artificial 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.

17、It would be extremely dangerous if they decide that humans are their enemies.Option2I 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 wil
