Question

The defeat of Lee Sedol，the world's strongest Go （围棋） player，by a Google artificial intelligence （AI） program，looks like another milestone towards a world where computers can do almost anything a human can．It is not．There are uncountable things that only a human can do，and that no computer seems close to．The problem is that the purely human things are not economically useful to anyone．The things that computers can be taught to do are by contrast economically fantastic．But even the most powerful programs are not human，just as a shovel （铲车）．They have no feelings．What they have is power，but this power is growing at a rate that should frighten us a ll．
It might be less frightening if computers were truly intelligent，but even the most powerful networks are less human than monstrous Martians （火星人）．Their power will be used to make money for the firms that finance their development，and then for others quick and clever enough to take advantage of the new world．It is far more likely that they will increase inequality and still further remove the middle classes as we move towards an hourglass （以金钱来衡量的） society in which everyone is either very rich or very poor and likely indebted．
One of the ill effects of the spread of more intelligent computer networks is，at the same time，the spread of what might be called artificial stupidity．If AI is employed largely to replace unskilled labour，it is most productive when labour is kept unskilled or redefined that way．So much of the work in service industries is now simplified until it might be automated （自动化）．And robots will never need pensions．AI is slowly reducing skilled work，like some forms of medical diagnosis，at the same time，as older doctors complain that the traditional human skills of diagnosis are falling out of medical training．The belief that everything worthwhile can be measured and then managed is far more damaging to humanity than the threat of artificial intelligence on its own．
But no victory in complicated Go games can bring us closer to truly human-like computers．

A．computers can completely replace humans in everything
B．humans are of no practical economic values to the society

52．We can learn from Paragraph 2 that the power of computers will___．
A．improve the quality of human life
B．promote equality at work places
C．make contributions to human development
D．widen the gap between the rich and the poor
53．What does"artificial stupidity"in Paragraph 3 mean？___
A．Unskilled workers become stupid．
B．AI discourages skilled work．
C．Computers don't need pensions．
D．AI is ruining medical training．
54．What is the author's attitude towards the future of artificial intelligence？___

C．Skeptical．
D．Disappointed．

Answer 1

51．C  细节理解题，根据第一段The defeat of Lee Sedol，the world's strongest Go （围棋）player，by a Google artificial intelligence （AI） program，looks like another milestone towards a world where computers can do almost anything a human can．It is not．可知作者提到Lee Sedol的失败是要告诉我们计算机的力量正以惊人的速度增长着，故选C．
52．D  推理判断题，根据第二段It is far more likely that they will increase inequality and still further remove the middle classes as we move towards an hourglass （以金钱来衡量的） society in which everyone is either very rich or very poor and likely indebted．可知学习计算机的力量会扩大富人和穷人之间的差距，故选D．
53．B  词义猜测题，根据第三段One of the ill effects of the spread of more intelligent computer networks is，at the same time，the spread of what might be called artificial stupidity．可知更智能的计算机网络的传播的不良影响之一是在同一时间传播可能被称为人工愚蠢，故选B．
54．C  细节理解题，根据最后一段But no victory in complicated Go games can bring us closer to truly human-like computers．可知作者对人工智能的未来的态度是保持怀疑的，故选C．
