新概念英语培训之详谈英语中的被动语态现象
被动语态是新概念系列中的一个重要语法,应用十分广泛,需要全面理解其定义,结构和特殊用法。
语态是动词的一种形式,用以说明句中主语和谓语的关系。如果主语是动作的执行者,动词形式为主动语态(The active voice);如果主语是动作的承受者动词形式为被动语态(The passive voice)。
例如:
1. Many people speak Chinese.(主动语态)
2. Chinese is spoken by many people.(被动语态)
一、被动语态的基本结构
被动语态的基本结构是“be +动词的过去分词”,而对于动词的各种时态的被动语态结构要做相应的变化。各种时态的被动语态如下:
1.一般现在时:主语+am/is/are+动词的过去分词
例如:English is spoken in Canada.
2.一般过去时:主语+was/were+spoken+动词的过去分词
例如:Many trees were planted last year.
3.一般将来时:主语+will/be going to be+动词的过去分词
例如:A new bridge will be built in this city next year.
4. 现在进行时:主语+am/is/are being+动词的过去分词
例如:The World Cup is being held in Germany now.
5.过去进行时:主语+was/were being+动词的过去分词
例如:My computer was being used by him when I went to get it back.
6.现在完成时:主语+have/has been+动词的过去分词
例如:Papers and printing have been used for ages.
7.过去完成时:主语+had been +动词的过去分词
例如:The bag had been left at home when I got to school.
8.情态动词:主语+情态动词+be+动词的过去分词
例如:Books can be replaced by computers.
二、何时使用被动语态
1.不知道谁是动作的执行者或没有必要时,如:
(1)Paper is made from wood.
(2)The house is quite old. It was built in 1950.
(3)He was wounded in the fight.
2.需要强调动作的承受者时,如:
(1)Calculator can't be used in the math exam.
(2)Books and newspapers in the reading room mustn't be taken away.
(3)He was awarded first prize in that contest.
三、主动语态和被动语态的转换
1.把主动语态的宾语改为被动语态的主语
2.把主动语态的谓语动词改为相应的被动语态的结构
3.把主动语态的主语改为“by+原主语(主格变宾格)”,放在主谓结构之后,在意思明确时by短语可以省略。
例如:
(1)We speak English.
(2)English is spoken by us.
四、被动语态需要注意的地方
1.只有及物动词有被动语态,不及物动词没有被动语态。
例如:
Great changes have taken place in our hometown these years.
2.含有双宾语的句子由主动语态变为被动语态时有两种情况:
(1)把间接宾语改为被动语态的主语,直接宾语仍留在原位。
(2)把直接宾语改为被动语态的主语,此时,间接宾语前要加介词to或 for。
例如:
She gave the boy a book.
The boy was given a book.或The book was given to the boy.
3. 短语动词是不可分割的整体,改为被动语态时,要保持其完整性,介词或副词不可漏掉。这样的短语有:look after, listen to, look at, pay attention to, take care of, look forward to, make use of ,etc.
例如:
(1)You must take care of your dog.
(2)Your dog must be taken care of.
4. 主动句中在感官动词see, look at, hear, listen to, feel, watch, notice及使役动词make, let, have等动词后应跟不带to的动词不定式,而在被动句中应加上不定式符号to。
例如:
(1)I saw Tom enter the room.
(2)Tom was seen to enter the room.
5. 有些被动语态结构成了习惯用法。
例如:
(1)It is said that… 据说…
(2)It is(was) reported that…据报道…
(3)It is well-known that…众所周知…
五、主动形式表被动意义的情况
1.动词need, require, want, deserve 等后接v-ing的主动结构常表被动意义。
例如:The book is worth reading.
2.open,lock,sell,read,write,clean,cut,wash,burn,teach,drive,shut等及物动词在用作不及物动词时,它们的主语为物,可用主动语态表被动意义。
例如:The car drives well.
3.look,taste,smell,seem,sound等连系动词主动形式表示被动意义。
例如:The dish tastes good.
