◆Themachinehasalreadybeenrepaired．机器已经修好了。2．表示一个被动的动作或状态开始于过去，持续到现在，并可能持续下去，常与for或since引导的时间状语连用，或用于“Howlong…？”句型中。◆Financialproblemsofthecomp

anyhavebeendiscussedfornearlytwohours．公司的财务问题已被讨论了近两个小时了。◆Howlonghasthisfilmbeenshown?这部电影已放映多长时间了？3．用在时间或条件状语从句中，表示将来某时已完成的动作，即用现

在完成时的被动语态代替将来完成时的被动语态。◆Youshouldn’tleaveschoolbeforeyourhomeworkhasbeenfinished．在你的作业没完成之前你不应该离开学校。常与现在完成时连用的时间状语有：already已经yet已经recently/lately最近sin

cethen从那时起eversince自那以来ever曾经sofar迄今为止bynow到现在为止foralongtime很长一段时间inrecentyears在最近几年里in/during/overthepast/lastyears在过去的几年里使用现在完成时的被动

语态要注意的问题1.现在完成时的被动语态、现在进行时的被动语态及一般过去时的被动语态的区别Themachinehasbeenrepaired.（说明动作发生在过去，对现在有影响，“现在修好了”）Themachineisbeingrepairednow

.（说明动作正在进行）Themachinewasrepairedyesterday.（只说明动作发生在过去）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，例如：工程已开始三个月了。Theprojecthasbeenstartedforthreemonths.（F）Theprojecthasbeenonforth

reemonths.（T）1.用现在完成时的被动语态改写句子①Jack'sbosshasalwayspraisedhimforhisdevotiontowork.Jack___________________________byhisbossforhisdev

plantedonthehillinthelast5years．1.现在完成时的被动语态强调一个发生在过去的被动性的动作，动作已完成并强调对现在造成的影响或结果，主语和谓语之间为被动关系。Thedoorhasalreadybeenlocked.门早已经

被锁上了。Ihavebeenemployedatthejobsince2015.自从2015年，我就做这份工作。2．基本构成现在完成时的被动语态的结构为has/havebeendone。Alotofmoneyhasbeenspenttoprotecttheoldtempleby

now.到目前为止已投入了大笔钱来保护这座古庙。Thesetreeshavebeenwateredlately.那些树最近已浇水。3．现在完成时的被动语态的各种句式肯定式主语＋have/hasbeendone...否定式主语＋have/hasnotbeen

done...一般疑问式Have/Has＋主语＋beendone...？特殊疑问式特殊疑问词＋have/has＋主语＋beenone...？NorthernChinahasbeensweptthroughbyastrongcold

windrecently.最近一股强冷空气横扫中国北方。[点津](1)若句子主语为第三人称单数时，助动词要用has。(2)用于现在完成时的时间状语有：sincethen,since＋从句，sofar,bynow,uptonow,recently,lately

,already,yet,inthelast/past＋一段时间等。(3)ever,never,already,yet等副词用于现在完成时的被动语态时，放在has或have之后。3.现在完成时的主动语态变被动语态（1）只带有一个宾语的动词变为被动语态时，将主

，tell，make，sing，write，read，sell，buy，pay，lend，pass，promise等，变为被动语态时，一般将间接宾语变为被动语态的主语，若将直接宾语变为被动语态的主语时，间接宾语前面要用相应的介词。Wehav

egivenhimthebook.→Hehasbeengiventhebook.→Thebookhasbeengiventohim.（3）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，原来的宾语补足语变为主语

补足语。AfterdecoratingtheAmberRoomwithjewels，theartistshavemadeitmoresplendid.→Afterbeingdecoratedwithjewels，theAmberRoomhasbeenmadem

oresplendid.[点津]带有复合宾语的动词变为被动语态时，若宾语补足语为省略to的不定式充当时，在被动语态中需将省掉的to加上。Thebosshasmadehiscompanyoffermorechancesforpeopletowork.→His

companyhasbeenmadetooffermorechancesforpeopletowork.(4)动词短语是一个不可分割的整体，在被动语态中要保持其完整性，其中的介词或副词不可省略。It'ssaidt
