been＋过去分词。StepII.Present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)Theworkwasfinishedtwoweeksago.这项工作于两周前被完成。Theworkhasbeenfinished.这项工作已经被完成。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。Ihavetoldthemtohelpyou.→Theyhavebeentoldtohelpyou.StepIII.PractiseⅠ.用现在完成时的被动语态改写句子1．Jack’sbosshasalwayspraisedhimforhisdevotiontowork.→Jackhasalwaysbeenpraisedbyhisbossforhisdevotiontowork.2．Theyhavefoundagoodplacetobuildatempleinthevillage.→Agoodplacehasbeenfoundtobuildatempleinthevillage.3．Wehaven’tyetdecidedhowtosolvethatdifficulttechnologicalproblem.→Howtosolvethatdifficulttechnologicalproblemhasn’tbeendecidedyet.4．Ihaveaskedhertohelpyou.→Shehasbeenaskedtohelpyou.5．Hehasgiventhechildsomeinterestingbooks.→Thechildhasbeengivensomeinterestingbooks.→Someinterestingbookshavebeengiventothechild.Ⅱ.语法填空(用所给词的正确时态、语态填空)1）LiMing：Hi,Linnicetoseeyouonthefirstdayofthenewterm!LinTao：Yes.Nicetoseeyouagain.LiMing：Iknowthatyourparents
