2．Over time I have been changed quite a lot．I began （56）as a calculating machine in 1642．It took nearly two hundred years（57）before I was built as an analytical machine．Then in 1936Alan Turing wrote a book and built a universal machine to solve any difficult mathematical problems．From then on，I grew rapidly both in sizes and brainpower．By the 1970s，I （58）had grown （grow）as large as a room and I wonder if I would grow any larger．（59）However，this reality also worried my designers．Luckily，（60）with time going by，I have been made smaller．And I （61）have been used （use） in offices and homes since the 1970s．These changes would not be possible without my improved memory，（62）which became so large that I couldn't believe it．In the early1960s，they gave me a family（63）connected（connect） by a network，enabling us to share my knowledge with others．Since the 1970s，many new （64）applications （apply） have been found for me and I have become important in many fields．I am now （65）truly （true） filled with happiness that I am a devoted friend and helper of the human race．
分析 文章以第一人称的口吻介绍了计算机的发展历史．计算机从一开始出现，到现在的广泛应用，其中经历了巨大的发展和演变．
解答 56．as；考查介词．句意表达的是1642年我一开始的身份是计算机，as以某种身份．
57．before；考查句型结构．时间段+before+从句，表示多久以后才…；句意表达的是花了将近两百年的时间我才被改造成分析仪．
58．had grown；考查时态．句中by the 1970s表示到过去某个时间为止已经完成的动作，是过去完成时态的用法．
59．However；考查副词．句意表达的是转折，且句中有逗号分隔，要用表示转折关系的副词however来构成．
60．with；考查介词．句中time后接分词，说明不能填连词；句意表达的是伴随情况，要用with来构成独立主格结构，意思是随着时间的推移．
61．have been used；考查时态和语态．句中use与主语I构成动宾关系，要用被动语态；时间状语since the 1970s表示从过去到现在，是现在完成时态的用法，因此use要用现在完成时态的被动语态．
62．which；考查连词．句中became so large that I couldn't believe it修饰名词memory，是一个定语从句；从句缺少主语，且先行词memory指物，要用which来引导．
63．connected；考查分词．句中connect作family的后置定语，要用非谓语动词；connect与family构成动宾关系，要用表示被动的过去分词来构成．
64．applications；考查名词．句中apply作主语，要用名词形式；前面有many修饰，application要用复数．
65．truly；考查副词．句中true修饰动词filled，要用副词形式．
点评 语法填空题是考查学生的语言运用能力．解题时，要在理解文章的基础上，灵活运用语法知识，如词性，时态，名词单复数，连接词，代词，冠词等判断空白处应填写的内容．答完后，还要通读全文，核对所填单词形式是否正确，是否符合语境．
