一 . 概念：

1. 说话时已经完成

的动作或出现的结果。

2. 主语是行为动作的承受者。

【注意】

1. 过去分词前有两个助动词have/has和been。

2. 必须表示被动。

I have been told about it many times．

The bridge has just been built．

二 句型：

1. 现在完成时被动语态肯定句句型：主语+ have/has been +过去分词 Her motorbike has been stolen.

2. 现在完成时被动语态否定句句型：主语+ have/has +not+ been+过去分词

The task has not been finished yet. Many workers have not been trained in the company.

3. 现在完成时被动语态一般疑问句句型：Have/Has +主语 + been+ 过去分词 ...?

Has a new computer been bought ? Have they been sent abroad to study English?

4. 现在完成时被动语态特殊疑问句句型：

疑问词+ have/has + 主语+ been+过去分词 ...? Where has the car been repaired?

Who have been helped by the new computer?

How many buildings have been built in this school?

三. 用法:

1. 表示一个被动的动作发生在说话之前,强调对现在造成的影响和结果。

The door has been locked.

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

The important problem has been discussed for nearly two weeks.

How long has the machine been used?

现在完成时的标志: recently /already/yet/

for+一段时间 / since+时间点

1. 只有及物动词才有被动语态,不及物动词(词组)没有

被动语态。

例如: happen, take place, die, appear, disappear,

fail, remain, lie, last, sit, stand, break out, come

true, belong to等。

What has happened to your brother?

2. 但许多不及物动词加介词或副词构成的动词短语，相当于及物

动词，也可以有被动语态。但动词短语是一个不可分割的整体，变为被动语态时,不可丢掉构成短语的介词或副词。

The child has been taken good care of by his

grandma all these years.

A notice has been put up on the wall.

3. 一些特殊动词, 如borrow, finish, begin, buy, start, return, 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, 则需改换动词或时态。

My brother has had(不能用has bought) this bike for

almost four years. Some exercises:

1. (2014·天津高考)We won’t start the work until all the preparations_________.

A. are being made

C. have been made B. will be made

D. had been made

【解析】选C。考查时态和语态。句意:我们在所有的准备做好之后才开始工作。until引导的是时间状语从句,一般不用将来时;这里强调完成,故选C。

2. (2013•北京高考)Shakespeare’s play Hamlet ____ into

at least ten different films over the past years.

A. had been made B. was made

C. has been made D. would be made

【解析】选C。考查时态和语态。句意:莎士比亚的戏剧《哈姆雷特》在过去几年里被制作成了至少十部不同的电影。时间状语over the past years与现在完成时连用,且主语与make之间是被动关系,故用现在完成时的被动形式。

3. —What’s happening in the new area?

—New houses _______ recently over there.

A. are built B. built

C. have built D. have been built

解析】选D。句意：——在那个新区发生什么事了？

——最近新房子已经在那里建起来了。主语与谓语动

词的关系为被动，故排除B、C两项。recently 常与现

在完成时连用。

4. There is a police car in front of our neighbor’s house. What do you suppose _______?

A. did happen B. has happened

C. is happen D. has been happened

解析】选B。句意：在我们邻居的房前有一辆警车。你认为发生什么事了？happen为不及物动词，无被动语态，故D项错误；A、C两项形式不正确。

5. This is one of the highest buildings that in our city recently. A. has been set up B. are set up

C. have been set up D. was set up 解析】选C。句意：这是最近在我们城市建的最高的大楼之一。关系代词指代的是buildings，故排除A、D两项；根据时间状语recently（常用于现在完成时）排除B项。

6. The construction of the two new railway lines _________ by now. A. has completed B. have completed C. have been completed D. has been completed 解析】选D。句意：这两条新铁路线的建设到现在已经完工了。根据句意应为被动结构，故排除A、B两项。主语是construction，为单数，故谓语动词用单数形式。
