被动语态的用法1．现在完成时的被动语态同它的主动语态一样，强调过去的动作对现在造成的影响或结果，通常与already,yet,just,never,recently等副词连用。◆Themachinehasalreadybee

nrepaired．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。◆Financialprobl

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sincethen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i

nrecentyears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。Theprojecthasbeenstartedforth

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

sbeenaskedtohelpyou．Manytreeshavebeenplantedonthehillinthelast5years．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。Alotofmoneyhasbeenspenttoprotecttheoldtemplebynow.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/hasnotbeendone...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...？NorthernChinahasbeensweptthroughbyastrongcoldwindrecently.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,ne

ver,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，将主动语态的宾语变为被动语态的主语。Tomhassoldout

allthemagazines.→AllthemagazineshavebeensoldoutbyTom.（2）带有双宾语的动词，如give，send，bring，take，teach，show，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。Wehavegivenhimthebook.→Hehasbeengiventhe

book.→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，theAmberRoomhasbeenmademoresplendid.[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.→Hiscompanyhasbeenmadetooffermorechancesforpeopletowork.(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'ssaidthattheproblemhasbeenlookedinto.据说已经调查了这个问题。单句语法填空1.They________________（sell）tenapartmentsinthepastoneho
