被动语态方面的知识
一、 被动语态的用法:
1.一般现在时的被动语态构成:is / am / are + done
2.一般过去时的被动语态构成:was / were + done
3.现在完成时的被动语态构成:has / have + been + done
4.一般将来时的被动语态构成:will+ be + done
5.含有情态动词的被动语态构成:情态动词+ be + done
6.现在进行时的被动语态构成:am / is / are + being + done
7.不定式的被动语态:to + be + done
二、 怎样把主动语态改成被动语态:
1.先找出谓语动词;
2.再找出谓语动词后的宾语;
3.把宾语用作被动语态中的主语;
4.注意人称、时态和数的变化.
例:1.Bruce writes a letter every week.→A letter is written by Bruce every week.
2.Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
3.He has written two novels so far.→Two novels have been written by him so far.
4.They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.
5.Lucy is writing a letter now.→A letter is being written by Lucy now.
6.You must lock the door when you leave.→the door must be locked when you leave.
三、 使用被动语态应注意的问题:
1.不及物动词无被动语态.
例:What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.
2.有些动词用主动形式表示被动意义.
例:This pen writes well.
This new book sells well.
3.感官动词或使役动词使用省略to的动词不定式,主动语态中不带to ,但变为被动语态时,须加上to .
例:make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4.如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定.
例:He gave me a book.→A book was given to me by him.
He showed me a ticket.→A ticket was shown to me by him.
My father bought me a new bike.→A new bike was bought for me by my father.
5.一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词.
例:We can’t laugh him.→He can’t be laugh by us.
He listens to the radio every day.→The radio is listened to by him every day.
The nurse is taking care of the sick man.→The sick man is being taken care of by the nurse.
