英语动词有两种语态,
主动语态(The Active Voice)和被动语态(The Passive Voice)。

hear see notice(2) see sb. doing sth. sb. be seen doing sth.I saw him playing football at that moment.He was seen playing football at that moment.hear / watch /….含有使役动词和感官动词的句子,变成被动语态的时候要记住:
不定式符号" to "
主动语态" to " 省略,
被动语态" to " 回来We often hear them sing this song.They are often heard to sing this song (by us).双宾结构,一般把表示人的间宾变为被动语态的主语。如果把表示物的直宾变为被动语态的主语时,要在宾语前加上to或for,是to还是for,要依据与它们搭配的动词来定。
He bought his friend some fruits yesterday.His friend was bought some fruits yesterday.Some fruits were bought for his friend yesterday.Bob sent Kate a letter last year.=Kate was sent a letter by Bob last year.=A letter was sent to Kate by Bob last year. send bring write
give teach pass lend…toMum made me a new dress.I was made a new dress by Mum.
A new dress was made for me by Mum.make
buy
draw…forI bought my brother a book.不及物动词没有被动语态,
但后面加上介词或副词后,
就变成了及物的短语动词,
就可以变为被动语态,
不过要特别注意短语动词中的介词或副词绝对不能丢失。
注意:约翰打开了收音机。John turned on the radio.The radio was turned on.奶奶照看我姐姐。Grandma takes care of my sister.My sister is taken care of by Grandma.注:千万不要遗漏介词或副词。We must speak to old people politely.Old people must be spoken to politely.必背!动词短语的被动语态take care of → be taken care ofcut down → be cut downlaugh at → be laughed atlook after → be looked after如果是宾语从句变
被动语态的话,只需要把主句变成被动即可They said that he would come back soon.It was said that he would come back soon.类似的还有:It is reported /

【正】You must look after yourself.
【误】Yourself must be looked after 英语主动形式表被动意义几种情况 英语中有时用动词的主动形式表示被动意义。现总结如下:
1.某些感官动词,如look,feel,sound,taste,smell等常用主动形式表示被动意义。例如:
The flower smells sweet.
The dish tastes delicious.
The cloth feels very soft.
2.某些动词,如sell,wash,write,lock,shut,close,open,read,
wear等,作不及物动词时常用主动形式表示被动意义。此时往往有程度副词出现尤其是有副词 well, easily例如:
His pen writes smoothly.
The window won’t shut.
This type of TV set sells well. The book sells well . ( 这本书销路很好。 )
The door will not open . ( 这扇门就是打不开。 )

4.need,want,require,deserve等动词后用V-ing主动形式表被动意义。句中主语是V-ing实质上的宾语。用作V-ing形式的动词若是不及物动词,后应加相应的介词。
The flowers need/want/require watering.
The problem required paying special attention to.5.在there be句型及with的复合结构中,可以用主动形式表被动意义。例如:
There is nothing to read.
There is nothing to do now.
There is nothing to worry about.
With so much work to do,Mary cannot but stay at home. There are a lot of work to do/ to be done.
There are a lot of work for us to do. 6.有些形容词后接不定式作状语时,常用主动形式表被动意义。此类形容词有easy,hard,difficult,cheap,expensive,fit,nice,good,funny,exciting,light,heavy,dangerous,comfortable,delicious等。动词是不及物时要加相应的介词。例如:
The fish is delicious to eat.
The ground is too hard to dig.
The chair is comfortable to sit on.
7.不定式作后置定语,与所修饰的词有动宾关系,又与句中其它名词或代词有主位关系,这时不定式用主动形式表被动意义。不定式为不及物动词时,其后应加相应的介词。例如:
Do you have anything to say?
He is a pleasant person to work with.8. 在“疑问代词 + 不定式”结构中。如:
I don‘t know what to do next. 我不知道下一步该做什么。
