现在完成时 被动语态 现在完成时的被动语态

现在完成时的被动语态
现在完成时的被动语态表示动作发生在过 去, 到现在已经完成或对现在仍有影响。
Understanding the structure of the present perfect passive voice The structure of the present perfect passive voice is: have / has + been+~ed

注意:
1. 副词的位置
often, usually, always, never, hardly, seldom等副词置于have / has和been中间。 如: [误] Such a man has been hardly
believed. [正] Such a man has hardly been
believed.

2. 并不是所有动词都有被动语态 1) happen, take place, break out, belong to, cost, last等不及物动词或词组无被 动语态。如: [误] Great changes have been taken place in China since 1978. [正] Great changes have taken place in China since 1978.

2) open, break, drop等不强调动作发出者 时常用主动语态。
3. 短语动词不可分割或省略其中的介词或 副词。如: The patients have been taken good care of.

4. 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。如:

My brother has had (不能用has bought) this bike for almost four years. How long has this book been bought? How long ago was this book bought?

主动语态变被动语态的方法
(1) 把主动语态的宾语变为被动语态的主 语。
(2) 把谓语变成被动结构 (be+过去分词) (根据被动语态句子里的主语的人称和 数,以及原来主动语态句子中动词的 时态来决定be的形式)。

(3) 把主动语态中的主语放在介词by之 后作宾语, 将主格改为宾格。例如:
All the people laughed at him. He was laughed at by all people. They make the bikes in the factory. The bikes are made by them in the factory.

(4) 双宾语动词变被动语态可将其中的一 个宾语变为主语, 另一个保留不动。 主动:I have given him the key. 被动:He has been given the key. 被动:The key has been given (to) him.

(5) 带复合宾语的动词变被动语态时, 只 能将宾语变为主语, 原来的宾补保留不动, 改称主语补足语。 主动:I have asked her to help you. 被动:She has been asked to help you.

1.现在完成时被动语态肯定句 主语+has/ have been +P.P.+...(P.P.=动词的过去 分词形式) Her motorbike has been stolen. 她的摩托车被盗了。
All the offices have been linked by computer. 所有的售票处由计算机联网工作。

2.现在完成时被动语态否定句 主语+has/ have +not+ been+ P.P.+... The task has not been finished yet. 任务尚未完成。
Many skilled workers have not been trained in the company. 这家公司并没有培养多少熟练工人。

3.现在完成时被动语态一般疑问句 [句型1]Has he(she, it,单数名词)+been+P.P.+...? Has a new computer been bought? 买了一台新电脑吗? Have they been sent abroad to study Eng-lish? 他们已经被派往国外学英语了吗?

4.现在完成时被动语态特殊疑问句 疑问词+have (has)+主语+been+ P.P.+...? What has been bought by Tom? 汤姆已经买了什么东西? Who have been helped by the new computer? 谁已经得到这种新计算机的帮助? How many buildings have been built in this school? 这所学校已经建造了多少座大楼? Where has the car been repaired? 这辆小汽车已经在哪里修理好了?

Practice
Turn the following into the Passive Voice.
1. We have planted some trees around the lake. Some trees have been planted around the lake .

2. My father has locked the door. The door has been locked.
3. Someone has turned off the light. The light has been turned off.

4. We will hold the Olympic Games in Beijing in the year 2008. The Olympic Games will be held in Beijing in the year 2008.
5. They have rebuilt the bridge. The bridge has been rebuilt.

试分析:
1) [误] Many new buildings been built since 2000.
[正] Many new buildings have been built since 2000.
[析] 谓语部分结构不全,时态部 分不完整。

2) [误] Something bad has been happened to him.
[正] Something bad has happened to him.
[析] 被动语态误用。happen为不及 物动词,不及物动词没有被动 语态。

3) [误] The door has been opened of itself.
[正] The door has opened of itself. [析] 有些动词如open, break, drop
等既可作及物动词,又可作不及物动 词,若不强调谁是动作发出者,我们 通常用主动语态。of itself意思是“自 动地”。因此, 此句不可用被动语态。

4) [误] I have introduced to Mr Li.
[正] I have been introduced to Mr Li (by Mr Wang).
[析] introduce为及物动词, I 是 introduce的承受者。
