12．Artificial intelligence：Google's AlphaGo beats Go master Lee Se-dol
A computer program has beaten a master Go player 3-0 in a best-of-five competition，in what is seen as a landmark moment for artificial intelligence （人工智能）．
Google‟s AlphaGo program was playing against Lee Se-dol in Seoul，in South Korea．
Mr Lee had been confident he would win before the competition started．
"AlphaGo played consistently （稳定地） from beginning to the end while Lee，as he is only human，showed some mental weakness，"one of Lee‟s coaches，Kwon Kap-Yong，told the AFP news agency．
Mr Lee is considered as a successful Go player，having won many competitions in his career．
Go is a game of two players who take turns putting black or white stones on a 19-by-19 grid （棋格）．Players win by surrounding their competitors pieces with their own．
In the first game of the series （系列赛），AlphaGo won by a very small chance-Mr Lee had led for most of the match，but AlphaGo managed to build up a strong lead in its closing stages．
After losing the second match to DeepMind，Lee Se-dol said he was"speechless"adding that the AlphaGo machine played a"nearly perfect game"．
Experts said that Lee Se-dol had brought his"top game"but that AlphaGo had won"in great style"．
The AlphaGo system was developed by British computer company DeepMind which was bought by Google in 2014．It has built up its special skills by studying older games and teasing out so many kinds of ways of play．And，according to DeepMind CEO Demis Hassabis，it has also spent a lot of time just playing the game．
"It played itself，millions and millions of times and each time got a little better-it learns from its mistakes，"he told the BBC before the matches started．
This good circle of continuous improvement meant the super computer went into the five-match series stronger than when it beat the European player late last year．
Does this mean artificial intelligence is now smarter than us and will kill us humans？Certainly not．AlphaGo doesn‟t care if it wins or loses．Does it mean that artificial intelligence will soon take your job？Possibly you should be more worried about that．

48．What had Lee Se-dol thought about the competition before it started？A
A．He would beat AlphaGo．
B．AlphaGo would lead the match．
C．It was hard to tell who would win．
D．AlphaGo would have some weakness．
49．What happened in the first game of the series？C
A．Mr Lee won by a very small chance．
B．AlphaGo had led for most of the match．
C．Mr Lee was beaten by AlphaGo finally．
D．AlphaGo built up a strong lead at the beginning．
50．What does the underlined phrase"teasing out"probably mean？B
A．Giving out．
B．Working out．
C．Running out．
D．Pointing out．
51．The writer may agree thatCin the future．
A．human will be killed by artificial intelligence
B．artificial intelligence will do everyt hing for human
C．people might lose jobs because of artificial intelligence
D．artificial intelligence will be much smarter than human．

Answer 1

分析 人工智能：谷歌研发的"AlphaGo"对阵围棋高手李世石．
电脑软件已经连下三城在5局3胜制的规则下完胜了大师级围棋高手，这已经成为了人工智能的一个历史性时刻．
今日，在韩国首尔，谷歌自行研究开发的‘阿尔法围棋'已经完成了与韩国围棋高手李世石的对弈．亲爱的‘小李子'在赛前曾拍着胸脯承诺一定能赢！
"AlphaGo"全程发挥稳定，李就没能做到，作为人类，他的脑力承受不了，"李的前师父，权甲龙对法新社如是说道．
小李子（李世石）是一名当之无愧的围棋圣手，他在传奇的职业生涯里已经赢下了数不清的专业比赛．围棋，众所周知，它是一项有两人各执黑白棋在19*19格的木板上进行的回合制游戏．它以围地多者为胜．
回到今天的话题，在系列赛的第一场比赛中，AlphaGo以微弱的优势获胜．小李子曾在比赛中的绝大部分时间里具领先之势，但是，AlphaGo在比赛收官阶段运营起了无可逆转的巨大优势．来到第二局对弈，在输掉这局后，小李子几近哑口无言，只是轻描淡写地补充到阿尔法几乎发挥到了完美．两位专家指出，小李子已经为我们带来了最顶尖的游戏！最顶尖的棋局，然而AlphaGo用更加华丽的风格赢下了这场紫禁之巅的对决．
那么我们就来看看阿尔法这个软件程式把～． AlphaGo系统最开发于英国公司DeepMind之手，于2014年被谷歌收购．AlphaGo是通过学习老棋局以及梳理他人对围棋的片段建立起来的．此外，根据DeepMind的CEO Demis Hassabis所说，AlphaGo也花了很长的时间进行真正的对弈．比赛前，Demis Hassabis向BBC的人员说道："AlphaGo能左右互搏！自己跟自己的另外一个版本对干，甚至它已经对弈了数以百万次的棋局．并且它的对弈水平也循序渐进地变得更好，它还能从自己所犯的错误中汲取经验教训哦．这个渐进式提高自身水平的良性循环意味着：AlphaGo在与小李子对弈的BO5的比赛时已经比去年打败欧洲围棋冠军时还要强势了哦！
这是否意味着，如今人工智能技术已比人类聪明？未来，渺小的人类将难逃灭顶之灾？当然不是．AlphaGo不在乎输赢，它甚至不在乎自己是否参与了这场对弈，当然也不会赛后沏杯茶给你．这场胜利是否意味着人工智能将在不久的将来抢了你的工作？也许这才是你应该担忧的．

解答 48．A．细节理解题 根据第四句"Mr Lee had been confident he would win before the competition started．小李子'在赛前曾拍着胸脯承诺一定能赢！"可知在比赛开始之前他认为可以赢得比赛．故选A．
49．C  细节理解题 问题：在系列赛第一场比赛中发生了什么？根据"In the first game of the series （系列赛），AlphaGo won by a very small chance-Mr Lee had led for most of the match在系列赛的第一场比赛中，阿尔法以微弱的优势获胜"，所以换种方式说是李先生被打败了．故选C．
50．B   词义理解题 teasing out的含义要根据句子"It has built up its special skills by studying older games and teasing out so many kinds of ways of play．AlphaGo是通过学习老棋局以及他人对围棋的解决方法中建立起来的"，在这里teasing out意思是解决，选项working out与之意思相近，故选B．
51．C 观点态度题 作者会同意那个观点？根据文章最后"Does it mean that artificial intelligence will soon take your job？Possibly you should be more worried about that．这场胜利是否意味着人工智能将在不久的将来抢了你的工作？也许这才是你应该担忧的．"，选项C说由于人工智能人们可能会失业的．故选C．

点评 本题主要讲述了人工智能与围棋高手对弈，围棋高手输给人工智能，由此引发人们的思考．在做题时要仔细阅读，认真分析，尤其是词义理解题，更要仔细对比思考．平时要多积累词语．
