古代，人类用数手指、摆石头、打草结的方法计数。唐朝末年，中国人发明了算盘。近代，人类开始使用手摇式计算机、机械式计算机等计算工具。随着社会的发展和进步，信息量在不断增加，需要计算和统计的数据越来越多,人们希望有一种能从事复杂计算和控制的工具。1946年2月14日，美国宾夕法尼亚大学诞生了世界上第一台电子数字计算机“埃尼亚克”（ENIAC，ElectronicNumericalIntegratorandCalculator电子数字积分计算机）,它采用穿孔卡输入输出数据，每分钟可以输入125张卡片，输出100张卡片。当时仅仅用于军事和科研工作，解决数学计算问题。在短短的半个世纪里，计算机技术迅猛发展，计算机不仅可以进行科学计算，还可以处理文字、图像和声音等多种信息。

2、电子计算机的发展

自ENIAC问世以来，计算机发展的4个阶段：

（1）第1代电子管计算机（1946—1957年）第1代电子计算机采用电子管作为主要元件，运算速度仅为几千次/秒。第1代电子计算机体积庞大，造价十分昂贵，主要用于军事领域的科学计算。（2）第2代晶体管计算机（1958—1964年）

第2代电子计算机的主要零部件采用晶体管，运算速度几十万次/秒。与第1代电子计算机相比，晶体管计算机体积小、省电、寿命长、可靠性大幅度提高。

（3）第3代中小规模集成电路计算机（1965—1970年）

第3代电子计算机的主要零部件采用集成电路，存储容量14兆字节，运算速度几十万次—几百万次/秒。计算机体积进一步减小、可靠性大大提高。这一时期计算机开始应用于各个领域。

（4）第4代大规模、超大规模集成电路计算机（1971年——现在）

第4代电子计算机的主要元件采用大规模、超大规模集成电路，计算机的体积更小，计算速度为几百万次~几十万亿次/秒。计算机的发展进入了以计算机网络为特征的时代。

现在完成时被动语态的结构为has/havebeendone,使用hasbeendone时主语为单数，使用havebeendone时主语为复数。如：Hisbookhasbeentranslatedintomanylanguages.

他的书已被译为多国语言。Thosebikeshavebeensoldout.那些自行车已卖完了。

2.现在完成时被动语态的概念

现在完成时被动语态强调一个发生在过去的被动性动作，它有两层意思：

(1)动作已经完成，强调对现在造成的影响或结果;(2)主语与谓语动词之间为被动关系。如：Ourclassroomhasbeencleaned,youneedn'tcleanitnow.我们教室已经被打扫过，你现在没必要再打扫了。Theseflowershavebeenwatered,youcangohome.这些花已经浇水了，你可以回家了。3.现在完成时被动语态的用法(1)不知道动作的执行者是谁时;Hisbikehasbeenstolen.他的自行车被偷了。(2)动作的执行者是泛指或不言自明时;Notabookinthelibraryhasbeentakenaway.图书馆里的书没有一本被人拿走。(3)可以说出动作的执行者但动作承受者是谈话中心或特别需要强调时;Mywatchhasbeenrepaired.我的表修好了。(4)出于委婉、礼貌而避免提及自己或对方时;Enoughhasbeensaidhereonthisquestion.关于这个问题，这里已经谈得不少了。

(5)文章标题、广告、新闻等中（常用省略助动词be的被动语态）；RoadBlocked.道路已被堵塞。

(6)动作的执行者不是人；

Thehousehasbeenwashedawaybythestorm.那栋房子已被暴风雨冲走了。

(7)书信起草人以公司名义起草商务书信。

Yourletterhasbeenreceived.来信已收到。

4.现在完成时被动语态的各种句型变换。

从现在完成时被动语态结构has/havebeendone可以看出has/have为助动词，因此现在完成时被动语态的各种句型变换均应借助于has/have来完成。构成否定句时直接在has/have后面加not，构成一般疑问句时将has/have提到句首。如：Hasthisbridgebeenfinished?这座桥竣工了吗？Hishomeworkhasn’tbeenfinished.他的作业还没做完。Theblackboardhasbeencleaned,hasn’tit?黑板已经擦过了，是吗？1.ThepriceofacolourTVset_____(降价了)again.2.Thetwobooks_____(未被拿走)byhim.3.Itissaidthatthehouse_____(闯进了)bytwothieves.4.Howmanyworkers_____(已派遣)tobuildtherailway?5.Youcanseethehouse_____(未油漆)foryears.
