    11．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．
    51．By mentioning the defeat of Lee Sedol，the author intends to tell us thatC．
    A．computers can completely replace humans in everything
    B．humans are of no practical economic values to the society
    C．the power of computers is growing at a frightening rate
    D．AI programs can not compare with humans economically 
    52．We can learn from Paragraph 2 that the power of computers willD．
    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？B
    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
    A．Optimistic．
    B．Supportive．
    C．Skeptical．
    D．Disappointed．

    15．The public ation of Harry Potter and the Half-Blood Prince pleases booksellers across China．The British and American editions were No.1 and No.3 separately on the sales chart of the Beijing Xidan Book Building last week．The book's poster is highlighted and news about the book can often be heard on the radio．   
        Why is the book so attractive to children？With curiosity，I got a copy of"Harry Potter"．At first，I wanted to glance over it and made some criticisms（批评）．But，out of expectation，I have been deeply attracted by the magic world．On the other hand，one can't help asking：Where is our own"Harry Potter"？
         The Chinese nation has a history of 5，000 years．With a vast market of youngsters．China did publish many books popular among children．However，why are the present works not as．good as those imported（进口的）？
         There come two major reasons：Firstly，quite a number of children's books are of strong sense of teaching，and lack interest and entertainment（娱乐）．Children often have a feeling of being"educated"．No wonder they don't like them．Secondly，children's reading materials involving"idiom stories"and"Chinese talents'stories"，though always in different covers，are usually much the same．Some books are plagiarized．The authors take words，ideas from someone else's work．One knows the ending as early as in the beginning．In final analysis，the authors of the books seldom take children's requirements into consideration．
        As a matter of fact，each child has his own wonderful imagination．They hope to understand the world and nature．Similarly they．have their own choices．They dislike similar stories．even if the stories are excellent．First-class reading for children should be very interesting，which contains knowledge and the essence（精髓）of national culture，which are presented in children's language．
        Market is a touchstone（试金石） for products．The theory also holds true for cultural products．It is hoped that the authors of children's books can learn something from the good market of"Harry Potter"and write out more and better books loved by children．
    47．Our own books have the following disadvantages EXCEPT thatC．
    A．they have little sense of interest and entertainment
    B．many of our books are of the same
    C．our authors know what our children need     
    D．the authors didn't pay much attention to the children's requirements
    48．What does the underlined word"plagiarized"in mean in Chinese？D
    A．改编   
    B．杜撰   
    C．印刷   
    D．剽窃
    49．The reason why Harry Potter and the Half-Blood Prince is so popular is thatA．
    A．it opens a magic world for children
    B．it has little sense of teaching
    C．it is only written in children's language
    D．it is advertised more on TV or poster
    50．What does the writer mean by writing"Where is our own Harry Potter"？C
    A．We Chinese produce more books than other countries．
    B．We are short of books for children and adults．
    C．Our authors are expected to make the children's book a real best-seller．
    D．Authors should write books named"Harry Potter"．
