Study

the Present Perfect Passive Voice 1. The meaning of the present perfect passive voice (1)表示发生在过去的动作对现在产生的结果或影响,而且这个动作是被动的。

单句语法填空

①(2018·全国Ⅲ)Their efforts _________(prove) fruitful.

(2)表示在过去发生的,一直延续到现在的并可能持续下去的被动动作或状态。常与for或since引导的时间状语连用,或用于“How long...?”句型中。

单句语法填空

②(2017·全国Ⅱ)Since 1958,they

_______________________ (recognize) as the national theatre of Israel. (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。

③You can go home as soon as your homework has been finished. 作业一做完你就可以回家。

2.Tips f using the present perfect passive voice (1)在现在完成时的被动语态中,have/has和been缺一不可。

阅读下列句子,指出哪些句子是现在完成时的被动语态。

④The computer was bought last Sunday. ⑤(2017·天津)I feel that I’ve been given a second life to devote to something that is meaningful and enormous. ⑥They have decided to finish the work as soon as possible. ⑦(2018·江苏)If you are a student studying the arts,chances are you have been ill-advised to have a plan B. 现在完成时的被动语态的句子______ (2)注意现在完成时的被动语态与一般过去时的被动语态的区别。一般过去时的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;而现在完成时的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结果或影响。

翻译句子

⑧The machine has been repaired.(说明动作发生在过去,对现在有影响,即:修好了。) 这台机器已经修好了。

⑨The machine was repaired yesterday.(只说明动作发生在昨天。) 这台机器昨天被修理了。

(3)不可与具体的时间状语连用(如yesterday,three days ago,in 1970,in 2050等),但可与不确定的时间状语连用(如already,yet,just,often,recently,in the past few years等)。

单句语法填空

⑩In the past few years,many tall buildings have been built (build) in this area. (4)有些动词如finish,buy,start,begin等,表示的动作很短暂,我们称之为短暂性动词或非延续性

动词。它们构成的现在完成时的被动语态不能与for,since构成的短语或引导的句子连用,也不能用于“How long...?”句型中。

翻译句子: 那项工作已经开始。

That job/work has been started. (5)带有双宾语的动词,如:give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,ask,pay,borrow,lend,offer,hand,pass,get,promise等,变为被动语态时,可将其中一个宾语变为主语。

变式训练

主动语态

I have given him the book.(改为被动语态) 被动语态1

He has been given the book (by me). 被动语态2 The book has been given to him (by me). (6)带有复合宾语(宾语+宾语补足语)的动词变为现在完成时的被动语态时,应将宾语变为主语,原来的宾语补足语保留。主动语态中省略to的不定式作宾语补足语的,被动语态中要还原to。

主动语态

I have asked him to help you.(改为被动语态) 被动语态 He has been asked to help you (by me). 主动语态

I have made him work hard.(改为被动语态) 被动语态 He has been made to work hard (by me).

(7)短语动词变为现在完成时的被动语态时,要注意保持短语动词的完整性,动词后面原有的介词或副词不可遗漏。此类短语动词有: a.动词+介词

look after,call on,rely on,look for,look at,listen to,dream of,meet with,laugh at,result in,wait for,do with,deal with,operate on,refer to,think of等

b.动词+名词+介词

pay attention to,make use of,take part in,keep an eye on,make fun of,catch sight of,set fire to,take hold of,take note of,take care of等

A way of doing it has been thought of (by him).

(8)现在完成时的主动语态变为被动语态应注意的几个问题: a.有些动词和动词短语没有被动形式,也不可用其过去分词作后置定语,如:break out,belong to,arrive,die,become,disappear,take place,happen等。

即学即练：单句改错

A war between the two countries has been broken out. 答案:去掉been As you know,great changes have been taken place in our city. 答案:去掉been

b.动词get,buy,sing,cook,fetch,make,spare,find等词的现在完成时的主动语态的直接宾语变为被动语态的主语,间接宾语前常加介词for;其他动词的间接宾语前常加介词to。

单句语法填空

c.如果被动结构中强调行为的工具或使用的材料,用介词with;若指明动作的执行者,则用介词by。
