5.A Google-developed supercomputer has beaten a South Korean Go(圍棋)grandmaster again,taking a commanding 2-0lead in a five-game series that has become an amazing global debut(首演)for a new style of artificial intelligence (AI).
After shocking the world by defeating Lee Se-dol-one of the greatest modem players of the ancient board game 一 in their opening match on Wednesday,the AlphaGo computer proved it was no luck with another victory after a tiring four-and-a-half-hour meeting.
"I am quite speechless,"Mr.Lee said after the match,adding he had found"no weakness"in AlphaGo's performance."I admit it was a very clear loss on my part.AlphaGo played a near perfect game today…I will try my best so that I will win at least one game."
The grandmaster had earlier predicted that he would beat the supercomputer by a"landslide".
The 33-year-old must win all three remaining matches to win the series that has a cash prize of $US 1million.
AlphaGo's creators have described Go as the"Mt Everest"of AI,mentioning the complexity of the game,which requires a degree of creativity and intuition(直覺)to defeat an opponent(對(duì)手)•
The most famous AI victory came in 1997,when the IBM-developed supercomputer Deep Blue beat Garry Kasparov,the then-world class chess champion,in its second attempt.
But a true mastery of Go,which has more possible move arrangements than there are atoms in the universe,had long been considered the unshared field of humans 一 until now.
AlphaGo first rose to fame with a 5-0defeating European champion Fan Hui last October,but it had been expected to struggle against 33-ycar-old Mr.Lee,who has topped the world rankings for most of the past decade.
The computer uses two sets of"deep neutral networks"that allow it to calculate data in a more human-like fashion 一 dropping millions of potential moves that human players would know were senseless.It also employs algorithms(運(yùn)算法則)that allow it to learn and improve from match play experience.

分析 本文屬于說(shuō)明文閱讀,作者通過(guò)這篇文章主要向我們描述了AlfaGo通過(guò)計(jì)算機(jī)上學(xué)習(xí)深層神經(jīng)網(wǎng)絡(luò),累計(jì)經(jīng)驗(yàn),戰(zhàn)勝了許多圍棋大師,成為一種新的人工智能.
解答 28.B.推理判斷題.根據(jù)第二段"the AlphaGo computer proved it was no luck with another victory after a tiring four-and-a-half-hour meeting"可知AlfaGo擊敗Lee Se dol兩次;故選B.
29.D.細(xì)節(jié)理解題.根據(jù)第三段:AlphaGo played a near perfect game today…I will try my best so that I will win at least one game;可知Lee Se dol希望自己在游戲系列獲得徹底的勝利;故選D.
30.A.推理判斷題.根據(jù)第三段"I am quite speechless,"Mr.Lee said after the match,adding he had found"no weakness"in AlphaGo's performance"可知Lee Se dol對(duì)AlphaGo的表現(xiàn)是十分驚訝的;故選A.
31.C.細(xì)節(jié)理解題.根據(jù)最后一段"The computer uses two sets of"deep neutral networks"that allow it to calculate data in a more human-like fashion"可知深中立網(wǎng)絡(luò)和算法是AlfaGo的勝利最重要的原因;故選C.
