双宾语的句子变被动
含有双宾语的动词在变为被动语态时，有以下三种情形：
一、有些双宾动词(如award, buy, give, leave, lend, offer, pay, show, teach, tell等)在变为被动语态时，既可把间接宾语(指人)变为被动语态的主语，而把直接宾语(指事物)保留下来(称为保留宾语)，也可把直接宾语(指事物)变为被动语态的主语，而把间接宾语改为介词to 或for引起的状语(到底用to还是for，与所搭配的动词有关)。比较：
He gave her some money. 他给她一些钱。 → She was given some money. →Some money was given to him.
He bought her a watch. 他给她买了一快表。 → A watch was bought for her. →She was bought a watch.
二、有些双宾动词(如bring, do, make, pass, sell, send, sing, write等)通常用直接宾语(指事物)作被动语态的主语，而将间接宾语用作保留宾语(其前根据情况用介词to或for)：
Father made me a doll. → A doll was made for me. He wrote her a letter.
→ A letter was written to her.
三、有些双宾动词(如answer, deny, envy, refuse, save, spare等)通常用间接宾语(指人)作被动语态的主语，而将直接宾语用作保留宾语： He answered me that question.
→ I was answered that question by him.

双宾语的句子变被动有两种变法。
例：The old man told us a story yesterday．（那位老人昨天给我们讲了一个故事。）
变法一：We were told a old story by the old man yesterday.
变法二：A old story was told to us by the old man yesterday.（这里要把省略的to 加上）
My father bought me a book.
---I was bought a book by my father.(把间接宾语提前）
--- A book was bought for me by my father.(把直接宾语提前，注意在间接宾语前添加相应的介词for/to,buy用for)
The teacher is going to tell us a story tomorrow.
----A story is going to be told to us by the teacher tomorrow . -----We are going to be told a story by the teacher tomorrow
Their teacher has taught them an American song.
-----An American song has been taught to them by their teacher ------They have been taught an American song by their teacher
1 He gave her some money. 他给她一些钱。 → She was given some money. →Some money was given to him.
2 He bought her a watch. 他给她买了一快表。 → A watch was bought for her. →She was bought a watch.
第一句中give to sb. 是词组，而第二句中的是buy sth. for sb. 也是词组。
Mother gave me a book last week，这句双宾语句怎么改被动语态？
这道题的原句Mother gave me a book last week是一般过去时，所以要改为一般过去时的被动语态。
1.I was given a book by mother last week . 又因为是give sth.to sb.所以变被动时sth.提前 2.A book was given to me by mother last week.
