二、现在完成时被动语态的主要用法

1 表示过去发生的动作对现在造成的影响与结果。当动词为短暂动词时，可与already或

Yet等词连用，但不能与for或since引导的表示一段的时间状语连用。例如：

1) The plan has been discussed for nearly 2 hours.

2．表示一个被动的动作或状态开始于过去，持续到现在，并有可能持续下去，常与for 或since引导的时间状语连用，或用于How long...？句型中。例如：

1) The plan has been discussed for nearly 2 hours.

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。

1) You can go home as soon as your task has been finished.

用动词的正确形式填空

1) Many new houses

(build )

in the village in the past few years. 2) The moon

already

(visit)

Joan

(give) you an English-

Chinese dictionary yet?

—

No. But I

(give) an English-

English dictionary 4)

Paper money

(use) for over a

thousands years. 5) How long

her work

(finish)?

把下句子改为被动语态

1.The cinema has shown more than 20 famous films.

2.They have made a plan to plant more trees.

3.He has offered me a good job.

三、使用现在完成时的被动语态要注意以下几点：

1．现在完成时的被动语态的两个助动词，即have/has和been，两者缺一不可。

2．与一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联系，而现在完成时的被动语态则强调与现在情况有联系。例如：

1) The library was built last year.

2) The library has been built. 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。例如：How

long has he joined the army？( )

How long has he been in the army？( ) 【注意】

这类动词的否定式可表示动作的持续过程，具有持续性，因而可与since或for构成的时间状语连用。
