英语被动语态常见的类型
1.当句子的主语是动作的执行者时,谓语的形式是主动语态.当句子的主语是动作的承受者时,谓语要用被动语态.被动语态由助动词be+过去分词构成,时态通过be表现出来.例如:
1)一般现在时:You are required to do this.
2)一般过去时:The story was told by her.
3)一般将来时:The problem will be discussed tomorrow.
4)现在进行时:The question is being discussed in the meeting room.
5)过去进行时:The new road was being made.
6)现在完成时:The novel has been read.
7)过去完成时:He said that the work had been finished.
8) 过去将来时:He said that the trees would be planted soon.
2.一些特殊的被动结构
1)带情态动词的被动结构:
The problem must be solved soon.
2)带不定式的被动结构:
The homework needs to be done with care.
3)短语动词的被动结构:
例1)The baby is looked after carefully.
用于这类被动结构的短语动词要把它们作为整体看待.这类结构有以下几种:
①(不及物)动词+介词:agree to,ask for,call for,laugh at,listen to,look after,operate on,send for,talk about,think of等.
②(及物)动词+副词:bring about,carry out,find out,give up,hand in,make out,pass on,point out,put away,put off,take up,think over,turn down,turn out,wipe out,work out等.
③动词+副词+介词:do away with,face up to,give in to,look down upon,make up for,put up with等.
例 2) Attention must be paid to your pronunciation.
用于这类被动结构的短语动词最多见的是“动词+名词+介词”这一结构.如:catch sight of,keep an eye on,make use of,make a fool of,pay attention to,put an end to,set fire /light to,take care of,take hold of,take notice of等.
例 2与例1的不同点在于,它们用于被动时态能有两种形式.第一种形式是把“动词+名词+介词”作为整体看待.第二种形式是把其中的“动词+名词”作为“动词+宾语”的结构处理.
4)带复合宾语的动词在改为被动语态时,一般把主动结构中的宾语改成主语,宾语补足语保留在谓语后面.例如:
We always keep the classroom clean.
(比较:The classroom is always kept clean.) 再答: 5)有些动词形式上是主动结构,但表示被动的意思。常见的有可和well, easily等副词连用的不及物动词sell, wash, write, read, clean, cook等。例如: The cloth washes well.这布很经洗。 The new product sells well.这新产品很畅销。 The pen writes well.这枝笔很好用。 6)下列情况主动句不能改成被动句: ①谓语是及物动词leave, enter, reach, suit, benefit, lack等。 ②谓语是不可拆开的短语动词take place, lose heart, belong to, consist of等。 ③宾语是反身代词,相互代词,同源宾语,不定式,动名词,抽象名词等。 7)汉语有一类句子不出现主语,在英语中一般可用被动结构表示。例如: 众所周知… … It is well known that … 有人会说… … It will be said that … 大家认为… … It is generally considered that … 有人相信… … It is believed that … 注意:这种结构可改为“Sb/Sth + be + pp + 动词不定式” 。例如: It is said that Tom has got the first place in the exam.=Tom is said to have got the first place in the place. It was reported that her mother died of SARS.=Her mother was reported to have died of SARS. 3. 主动表示被动含义 主动表示被动含义的句子的主语通常是表示物的词(指人的极少),而且这种物都具有某种内在的特点,能够促进动词所表示的动作得以实现或难以实现。这时的动词一般是不及物动词。例如:
