The Present Perfect Passive Vice
Can yu pick ut mre than tw sentences in the present perfect passive vice frm the reading passage?
现在完成时的被动语态的谓语构成形式：The results f their experiments have already been published.The party has been planned since the new year.肯定式：have / has（has只用于第三人称单数，其余人称用have） + been + 及物动词的过去分词。
They haven’t been tld abut it yet.否定式：_____________________+及物动词的过去分词。—Have his bks been sld ut?—Yes. S yu can’t buy ne nw. 一般疑问句形式：______________________+及物动词的过去分词。
have / has + nt + been
Have / Has +主语+ been
Hw many experiments have been dne by the students this mnth?特殊疑问句形式：疑问词 + have / has + been +及物动词的过去分词。
现在完成时的被动语态通常有以下两种情况：表示过去开始的被动动作一直持续到现在，常与之连用的时间状语有：fr +一段时间，since +时间状语（从句），these days, s far, up t nw, in the last / past few years等。
e.g. This class have been taught by Mr. Brwn fr tw years. His Chinese has been imprved a lt since he came t China. JK Rwling’s nvels have been translated int many freign languages s far.
表示某被动动作对现在造成的影响或结果，常与already, yet, just, ever, never, recently等连用。 e.g. The bike has nt been repaired yet. I have already been intrduced t Mr. Smith.
【注意】1) 现在完成时被动语态的两个助动词：have／has和been缺一不可。2) 注意与一般过去时被动语态的区别。 一般过去时被动语态表示一个被动的动作发生在过去，其结果对现在没有影响；而现在完成时被动语态的动作或状态尽管发生在过去，但侧重说明该动作或状态对现在造成的影响或结果。
e.g. The machine has been repaired． 机器已经修好了。(说明动作发生在过去，对现在有影响，修好了。) The machine was repaired yesterday． 机器昨天修了。(只说明动作发生在昨天。)
3) 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。 e.g. The rphans have been taken gd care f here． 孤儿们在这里受到很好的照顾。
4) 并不是所有动词都有被动语态 happen, take place, break ut, belng t, cst, last等不及物动词或词组无被动语态。 [误] Great changes have been taken place in China since 1978. [正] Great changes have taken place in China since 1978.
5) 一些特殊动词, 如brrw, finish, begin, buy, start, return, 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，则需改换动词或时态。 如：
My brther has had (不能用has bught) this bike fr almst fur years. Hw lng has this bk been bught? Hw lng ag was this bk bught?
6) 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。 e.g. We have built many huses in the past ten years. →Many huses have been built in the past ten years.
7) 带有双宾语的动词，如give, send, bring, take, teach, shw, tell, make, sing, write, read, sell, buy, tell, pay, lend, pass, prmise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。 e.g. We have given him the bk. →He has been given the bk. →The bk has been given t him.
8) 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t的不定式作宾补的，被动语态中要用带t的不定式。 e.g. I have tld them t help yu. →They have been tld t help yu. I have made her wrk hard. →She has been made t wrk hard.
