Functin:Active sentences are used ften, as they are mre direct. Passive sentences are ften used when the der f an actin is unknwn, nt imprtant, r preferred nt named.
The Present Perfect Passive Vice1. 形式：（1）肯定式：主语 + have/has + been dne + 其他 A 90-year-ld has been awarded “Wman Of The Year” fr being Britain’s ldest full-time emplyee — still wrking 40 hurs a week.一位90岁的老人被授予“年度女性”称号，因为她是英国年龄最大的全职员工——仍然每周工作40小时。（2）否定式：主语+ have/has nt been dne + 其他 They haven’t been tld the exciting news yet, have they?还没有人告诉他们这个令人激动的消息，是吗？
The Present Perfect Passive Vice1. 形式：（3）一般疑问式：Have/Has + 主语 + been dne + 其他?— Has her wrk been finished? 她的工作完成了吗？— Yes, it has. 是的，完成了。（4）特殊疑问式：特殊疑问词 + have/has + 主语 + been dne + 其他？Hw lng has the machine been used?这台机器使用多久了？
The Present Perfect Passive Vice2. 用法：（1）表示被动的动作到说话时刻为止已经完成，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，since，recently，s far，by nw，up till/t nw，ver/in the past/few years等连用。Despite the previus runds f talks, n agreement has been reached s far by the tw sides.尽管进行了前几轮谈判，但双方迄今仍未达成任何协议。Shakespeare’s play Hamlet has been made int at least ten different films ver the past years.莎士比亚的戏剧《哈姆雷特》在过去的几年里被拍成了至少十部不同的电影。
The Present Perfect Passive Vice2. 用法：（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fr或since等引出的时间状语（从句）连用，或用于hw lng引出的句子中。The machine has been repaired fr tw hurs.这台机器已经被修理两个小时了。（可能还会继续被修理）（3）用于时间或条件状语从句中，表示将来某时以前已经完成的动作。We’ll start as sn as the wrk has been finished.这份工作一完成我们就立即动身。
The Present Perfect Passive Vice3. 注意：（1）非延续性动词，如brrw，finish，begin，start，buy，marry，pen，jin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。工程已开始三个月了。The prject has been started fr three mnths.（F）The prject has been n fr three mnths.（T）（2）现在完成时的被动语态与一般过去时的被动语态的区别：The machine has been repaired.（说明动作发生在过去，对现在有影响，“现在修好了”）The machine was repaired yesterday.（只说明动作发生在过去）
The Present Perfect Passive Vice4. 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。Tm has sld ut all the magazines. All the magazines have been sld ut by Tm.（2）带有双宾语的动词，如give，send，bring，take，teach，shw，tell，make，sing，write，read，sell，buy，pay，lend，pass，prmise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。We have given him the bk. He has been given the bk./The bk has been given t him.
The Present Perfect Passive Vice4. 现在完成时的主动语态变被动语态：（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。After decrating the Amber Rm with jewels, the artists have made it mre splendid.After being decrated with jewels, the Amber Rm has been made mre splendid.注意：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t的不 定式充当时，在被动语态中需将省掉的t加上。The bss has made his cmpany ffer mre chances fr peple t wrk. His cmpany has been made t ffer mre chances fr peple t wrk.
