Question

15．A computer program has beaten a human champion at the ancient Chinese board game
Go．It marked an important advance for the（61）development（develop） of artificial intelligence．The program，（62）called（ call ） AlphaGo，had taught itself how to win．It beat the European champion in all five games of a match in October．The developers say（63）its（it） learning ability may someday let computers help solve real-world problems．Those could include making medical diagnoses and （64）conducting（conduct） scientific research．
Previously computers have beat humans in other（65）games（ game）．But among classic games，Go has long been viewed as the most challenging for artificial intelligence to master．
Go originated in China more than 2，500 years ago．（66）Thegame involves two players who take turns putting markers on a checkerboard-like grid．The object is to surround more area on the board with the markers than one's opponent （对手）．players obtain the opponent's pieces（67）bysurrounding them．The rules are simple，（68）butplaying it is not．It's probably the most complex game ever created by humans．
Martin Mueller，a computing science professor，（69）has worked（work） on Go programs for 30 years．He said the new program"is really a big step up from everything else（70）thatwe've seen．It's a very impressive piece of work．"

Answer 1

分析 本段文字讲述了一个计算机程序在中国古代围棋大赛中打败了人类在这个领域的冠军，这将极大地促进人类智能的发展，开发者认为计算机程序的学习能力可能某天会让电脑帮助解决真实世界中的问题．先前的计算机程序曾经在其他的游戏上打败过人类，但围棋被认为是对人工智能最具有挑战性的．围棋于2500年前起源于中国，它的规则很简单，但是玩起来很复杂．一位计算机科学教授Martin Mueller认为，这个程序是一项非常了不起的工作．

解答 61．development；考查名词，空格前是定冠词the，后面应该跟名词，故用development．
62．called；考查分词作定语，动词call和句子的主语是被动关系，所以用过去分词作后置定语．
63．its；考查代词，分析句子可知这里的it指代上文的A computer program，空格后面是名词短语learning ability，所以空格处用名词性物主代词its．
64．conducting；考查并列成分，句中and连接两个并列成分，作include的宾语，前面的动词make用了动名词形式，后面的conduct也要用动名词形式．
65．games；考查名词复数，空前的代词other指"其他的"，结合上下文，这里所提到的游戏不止一个，所以用复数形式．
66．The；考查冠词，结合上下文语境，空格后面的game是上文所提到的，所以用定冠词表示特指．
67．by；考查介词，空格后面是动名词，所以空格处应该用一个介词，结合句意，此处表明一种方式，所以这里用by表示方式．
68．but；考查连词，分析句子可知空格处缺少连词，结合上下文句意，前后两个句子是转折关系，所以用but．
69．has worked；考查动词的时态，结合上下文，根据句子中的标志性时间状语for 30 years可知，本句要用现在完成时，所以空格处填has worked．
70．that；考查定语从句，此处用that引导定语从句，关系代词that作从句的宾语．

点评 首先要通读全文，了解大意，抓住上下文语境所提供的信息，仔细分析带空格的句子，明确空格所要填的词义，词型和短语搭配给出所要填的正确形式，然后整体阅读短文，核对答案
