一些特殊结构的被动结构一些特殊结构的被动结构 : : 情况 1. 感觉动词 (hear, see 等 ) 改被动语态 使役动词 (let, make 等 ) 改被动语态

如动词为 make, see, hear, watch 等，后接宾语补足语为不带“ to” 不定式时，变被动语态时要加上“ to” 。如：典型例题 2 ： I saw him fall off the tree. →He was seen toto fall off the tree.

2 ． He makes her horse work all day.

Her horse all day.

3. My father let me go out for a picnic.

I out for a picnic.

is made to to work

was let to to go

口诀，这些动词真奇怪，主动句中 to 离开，被动句中 to 回 来。（ hear, let ， have, make, see, watch…)

总结：

特别提示： see sb. doing sth. 变成 sb. be seen doing sth.

典型例题：

3 .I saw him playing football at that moment. 变被动

He was seen playing football at that moment.

类似的还有： hear / watch /….

情况情况 2.2.带有带有双宾语双宾语（宾语既有人又（宾语既有人又有物）的被动结构是有物）的被动结构是 ::

（（ 11 ）将）将间接宾语间接宾语 (( 人人 )) 变为主变为主语，直接宾语语，直接宾语 (( 物物 )) 不变。不变。（（ 22 ）将）将直接宾语直接宾语 (( 物物 )) 变为主变为主语，一般要在间接宾语前语，一般要在间接宾语前加介词加介词toto 或或 forfor..

典型例题： 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.

类似的还有： tell ask bring write give send show teach pass lend

..to

思考：将下列的主动句变为被动语态：思考：将下列的主动句变为被动语态： 1.We gave him some books.

→He .

Some books .

was given some books (by us)

were given toto him (by us)

情况 3 ：动词短语变被动时 , 千万不要遗漏介词或副词

动词短语的被动语态动词短语的被动语态take care of take care of → → be taken be taken care ofcare of

cut down cut down → → be cut downbe cut down

laugh at laugh at → → be laughed atbe laughed at

look after look after → → be looked be looked afterafter

情况 5 ：反身代词在句中作宾语时，不能用被动语态。例如：
