被动语态
被动语态是动词语态的一种形式,表示主语是动作的承受者。在历年的中考题中,都有一定数量的考查被动语态的题目。因此,有必要对被动语态进行系统复习。
· 掌握被动语态的结构
被动语态由“助动词+及物动词的过去分词”构成。不同时态的被动语态的差异主要体现在助动词be的变化上,同时助动词be还要在人称和数上与主语保持一致。现将初中阶段常见的几种时态的被动语态总结如下:
1. 一般现在时的被动语态:am/ is/ are+done (指及物动词的过去分词,下同)
如:English is used all over the world.
2. 一般过去时的被动语态:was/ were+done
如:The picture was painted two years ago.
3. 现在进行时的被动语态:am/ is/ are+being+done
如:The flowers are being watered by them now.
4. 现在完成时的被动语态:have(has)+been+done
如:The room has been cleaned.
5. 一般将来时的被动语态:will/ be going to+be+done
如:The work will be finished tomorrow.
6. 含有情态动词的被动语态:情态动词+be+done
如:Your homework must be handed in today.
其它几种特殊句型:
①It is said that …….. ②It is well known that ……. ③It is reported that…….. ④have sth done
· 掌握主动语态变被动语态的方法
把主动语态变为被动语态时,应走好以下三步:
①主动语态的宾语变为被动语态的主语;②主动语态的谓语动词由主动语态形式变为被动语态形式;③主动结构的主语变为介词by的宾语,组成介词短语,放在被动结构的谓语动词之后。在无须说明动作的执行者或只强调动作的承受者时,by短语可以省略。
主动语态:My brother repaired that bike yesterday.
主语 谓语动词 宾语 其余部分
被动语态:That bike was repaired (by my brother) yesterday.
主语 谓语动词 by+宾语 其余部分
对于主动语态变为被动语态方法的考查,主要在句型转换题目中出现。只要能够按照上面介绍的方法去做,一般是能够做对的。
· 注意主动语态变为被动语态的几种特殊句型
1. 含有短语动词的被动语态
一般来说,只有及物动词才有被动语态。另外,许多不及物动词加上介词或副词构成的短语动词,相当于及物动词,后面也可加宾语。在变被动语态时,注意不可丢掉后面的介词或副词,常见的这类短语动词有:take care of, look after, take off, look at, send for, look up等。
如:The old people should be taken good care of.
2. 含有双宾语的动词的被动语态
含有双宾语的主动句改为被动句时,应将其中一个宾语改为被动结构的主语,另一个宾语仍保留在原处。一种情况是把间接宾语(指人)变为主语,直接宾语(指物)不变。另一种情况是把直接宾语(指物)变为主语,间接宾语(指人)不变,这时,间接宾语前通常加介词to,有时加for。
如:My father gave me a new book on my birthday.→
I was given a new book (by my father) on my birthday. (间接宾语作了主语)
A new book was given to me (by my father) on my birthday. (直接宾语作了主语)
3. 带有复合宾语的动词的被动语态
带有复合宾语(宾语和宾语补足语)的主动语态变为被动语态时,只把宾语变为被动语态的主语,原来的宾语补足语不动。同时,如果宾语补足语是省略to的动词不定式,变为被动语态时,必须加上不定式符号to,这类动词有make, let, see, hear, watch等。
如:We find English very useful.→ English is found very useful.
宾语 宾补
I often hear him sing in his room.→ He is often heard to sing in his room.
宾语 宾补
4. 有的动词的主动形式可以表示被动意义,这类动词有:wash, sell, smell, taste, sound, feel等。
如:The books sell well. The food tastes good.
以上四种情况在中考题目中经常出现,同学们在碰到类似题目时,应首先分析属于哪种情况,然后再根据掌握的知识来做题。
· 被动语态考点归纳
1. 主动语态改为被动语态时,被动语态应和主动语态的时态保持一致。
如:We speak English. (改为被动语态) English by us.
析:此句主动语态为一般现在时,被动语态也应用一般现在时,因此,答案应是is spoken。
2. 注意被动语态的谓语结构。
一般现在时是:am / is / are + p.p;一般过去时是:was / were + p.p;现在完成时是:have / has been + p.p;现在进行时是:am / is / are + being + p.p;含有情态动词的是:情态动词+be + p.p。
有诗曰:被动语态须注意,谓语不离“be”“p.p”。主谓一致别忘记,“进行”易丢一个“be”。
(注:p.p过去分词)。
如:We must take good care of our eyes. (改为被动语态) Our eyes must good care of.
析:此句中含有情态动词must,那么,我们根据“情态动词+be+p.p.”的公式可知,答案应是be taken。
3. 注意句中主谓语的一致关系。
如:Tea (grow) in southeast of China and India.
析:此句中主语tea是不可数名词,作主语时谓语动词应用单数形式。而此句说明的又是一自然现象,因此就应用一般现在时态。所以,答案应是is grown。
4. 注意复合宾语的变化。
如:They couldn’t make the cow go. (改为被动语态)
析:the cow go在句中作make的复合宾语。一般情况下,变为被动语态后,宾语补足语的结构形式、所处位置原封不动地保存下来,但make / have / let / see / watch / hear 等后原省略的to要还原回来。显然,此句中,the cow go 中省去的to应还原回来,因此答案应是The cow couldn’t be made to go.
5. 注意双宾语的变化。
如:Mr Smith showed the students two pictures yesterday. (改为被动语态)
Two pictures the students by Mr Smith.
析:变为被动语态时,双宾语中的任何一个皆可变为主语,一般变直接宾语,但间接宾语前必须加上介词to或for。此句中显然是把直接宾语变为被动语态的主语,那么,间接宾语前须加上介词to,所以答案应是were shown to。
6. 注意短语动词中的“小词”。
如:The old men and the children ____ in our country.
A. must take good care B. must be taken good care C. must be taken good care of D. must take good care of
析:短语动词是一个不可分割的整体,应当做一个词来看待,变成被动语态后,“小词”不能丢弃。因此,此题答案应是C。
