题目内容
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.
