语法精析现在完成时的被动语态一、用法1.现在完成时的被动语态与其主动语态一样,强调过去的动作对现在造成的影响或结果。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,常与fr或since引出的时间状语连用。The task has already been finished.任务已经完成了。The plan has been discussed fr tw hurs.这个计划已讨论两个小时了。
3.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s far,by nw,up till nw等连用。The rm has already been cleaned.这个房间已经被打扫干净了。(现在已经不用打扫房间了)The dctr hasn't been sent fr yet.还没有派人去请医生。(现在应派人去请医生)
注意事项1.与一般过去时的被动语态的区别:一般过去时仅表示发生在过去的动作,对现在无影响。2.非延续性动词的现在完成时的被动语态,如:buy,brrw,begin,finish,jin,die等不能与表示一段时间的状语连用。3.带双宾语动词的句子变成被动语态时,一般把表“人”的宾语(间接宾语)变为主语,若将直接宾语变为被动句的主语,间接宾语前要加t或fr。如动词为give,send,pass,take等时常加t;动词是buy,make,find等时常加fr。
4.带有复合宾语,即“宾语+宾语补足语”的动词,其所在的句子变为被动语态时,将宾语变为主语,原来的宾语补足语仍留在原处。主动语态中不带t的动词不定式做宾语补足语,在被动语态中要把t加上。
5.有短语动词的句子变为被动语态时,要注意保持短语动词的完整性,不能遗漏短语动词的介词或副词。如:refer t,lk after,listen t,laugh at,deal with,turn t,carry ut,set up, think ver等。The prgramme was dwnladed just nw.这个程序是刚才下载下来的。
He has sent me a card.(改为被动语态)①I have been sent a card.②A card has been sent t me.I have bserved her enter the ffice.(改为被动语态)She has been bserved t enter the ffice.The prject has been carried ut.这个工程已得到执行。
