情态动词 + be +动词的过去分词 二、主动语态变被动语态 口诀:宾变主,主变宾,谓变be done ,时不变,数格必须随被变。

注:1.主动、被动的时态要一致。

2.主动、被动的句式要一致。

3.变成的被动语态的主语与谓语在单复数上保持一致。

三、特殊情况的被动语态 1.带双宾语的被动语态:

动词+ sb (间宾) +sth (直宾)

口诀:如遇双宾语,一般变间宾,若把直宾变,to /for 间宾连。

1).give/pass /show 与介词to 搭配。

give sb sth —— sb +be given sth 或 sth +be given +to sb .

Eg. He gave me a book.

I was given a book by him.

A book was given to me by him.

2).buy/make/cook 与介词for 搭配。

buy sb sth —— sb +be bought + sth 或 sth +be bought +for sb

Eg. My mother bought me a cake .

I was bought a cake by my mother

A cake was bought for me by my mother .

2.带省to 的不定式作宾补的被动语态:动词+ sb + do sth .

口诀:感使动词真叫怪,to来to去记心怀,主动语态to离去,被动语态to回来。

动词:make / let /have /see /hear /feel /watch

make sb do sth ----sb + be +made +to do sth

Eg. The boss made the workers work all day

The workers were made to work all day by the boss.

4.以动词短语作谓语的主动语态变被动语态时,不可丢掉后面的介词或副词。

Eg. We should take care of the old .

The old should be take care of .
