DiscoveringUsefulStructures—ThepresentperfectpassivevoicePART1语法导学感悟规律重点难点剖析感知以下句子，完成方框下的小题◆语法感知1.MuchhasbeenwrittenaboutthewondersoftheWorldWideWeb.2.People’sliveshavebeenchangedbyonlinecommunitiesandsocialnetworks.3.Manypeoplehavebeenhelpedbytheclub.4.Jan’slifehasbeengreatlyimprovedbytheInternet.5.AkindofnewPChasbeenbuiltwithmorefunctions.1.以上句子中所使用的时态和语态是

。2.现在完成时的被动语态的构成为：

。现在完成时的被动语态have/has

been＋过去分词现在完成时的被动语态表示到现在为止某事已经被完成或被做。这种语法项目既要表示现在已经完成又要表示被动的含义，因此很多同学在具体运用中容易顾此失彼，难以把握。运用现在完成时的被动语态时应掌握以下几个问题：一、现在完成时的被动语态的常用句式◆语法精析肯定式主语＋have/hasbeendone...否定式主语＋have/hasnotbeendone...一般疑问式Have/Has＋主语＋beendone...？特殊疑问式疑问词＋have/has＋主语＋beendone...？Hehasbeenadmittedtotheclub.他已被接纳为俱乐部成员了。Tom’snovelhasnotbeenpublished.汤姆的小说还没有被出版。Hashisbikebeenrepaired?他的自行车修好了吗？Whohasbeeninvited?谁受到了邀请？二、现在完成时的被动语态的用法1.表示被动的动作在说话之前已经完成，强调过去的动作对现在造成的影响或产生的结果，通常与already，yet，never，recently等副词及时间状语sofar，bynow，uptill/tonow，since等连用。Theroomhasalreadybeencleaned.这个房间已经被打扫干净了。(现在已经不用打扫房间了)2.表示一个被动的动作或状态从过去开始一直持续到现在，并可能继续持续下去，常与for或since等引出的时间状语(从句)连用，或用于howlong引出的句子中。Themachinehasbeenrepairedfortwohours.这台机器已经被修了两个小时了。(可能还会继续被修)3.用在条件状语从句中，表示将来某时已经完成的动作。Youshouldn’tleaveschoolbeforeyourhomeworkhasbeenfinished.在你的作业没完成之前你不应该离开学校。三、使用现在完成时的被动语态要注意6点问题1.与一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联系，而现在完成时的被动语态则强调与现在的情况有联系。Theparkwasopenedtothepubliclastyear.去年这个公园向公众开放。(说明动作发生于过去)Theparkhasbeenopenedtothepublic.这个公园已向公众开放。(说明动作发生于过去，但对现在有影响，即现在公园已经向公众开放了)2.非延续性动词，如borrow，finish，begin，start，buy，marry，open，join等构成的现在完成时的被动语态不能与表示一段时间的状语连用。若要表达相应的意思，则要改换动词或时态。Theworkwasfinishedtwoweeksago.这项工作于两周前被完成。Theworkhasbeenfinished.这项工作已经被完成。3.短语动词是一个不可分割的整体，在被动语态中要保持完整性，其中的介词或副词不可省略。Itissaidthattheproblemhasbeenlookedinto.据说已经调查了这个问题。4.只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被动语态的主语。Wehavebuiltmanyhousesinthepasttenyears.→Manyhouseshavebeenbuiltinthepasttenyears.5.带有双宾语的动词，如give，send，bring，take，teach，show，tell，make，sing，write，read，sell，buy，tell，pay，lend，pass，promise等，变为被动语态时，可将其中一个宾语变为主语，另一个保留不动。

Wehavegivenhimthebook.→Hehasbeengiventhebook.→Thebookhasbeengiventohim.6.带有复合宾语的动词变为被动语态时，只能将宾语变为主语，原来的宾补改为主语补足语。原来省略to的不定式作宾补的，被动语态中要用带to的不定式。
