现在完成时的被动语态

一. 概念

1.Our classroom has been cleaned，so you needn't clean it now. 2.The letters have not been typed by now. 3.Have the clothes been washed? 二. 现在完成时被动语态的构成

现在完成时被动语态的肯定式和否定式的构成: have(has) been done 三. 现在完成时的被动语态的用法

1．表示被动的动作发生在说话之前（即现在的过去），强调对现在造成的影响和结果。

2．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。

四. 使用现在完成时的被动语态需要注意的问题

1．现在完成时的被动语态有两个助动词，即have(has)和been，两者缺一不可。

He has repaired the computer.

Have they painted the door? →The computer has been repaired by him.

→Have the door been painted? 2．注意与一般过去时被动语态的区别。

(1)一般过去时的被动语态表示一个被动的动作发生在过去某个时候，其结果对现在没有影响；(2)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和结果。例如：

The house was built last year.这房子是去年建造的。

The house has been built.这房子已经建好了。

3．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。

How long has this dictionary been borrowed？(×) 4

4．短语动词是一个不可分割的整体，在被动结构中要保持完整性，不可省略短语动词中的介词或副词。例如：

The police have looked into the problem.

→The problem has been looked into by the police. 注意:并不是所有动词都有被动语态:happen, take place, break out, belong to, cost, last等不及物动词或词组无被动语态。
