⑵teach ,give ,pass ,show ,buy, tell等动词常常带有两个宾语（双宾语：直接宾语和间接宾语），改为被动语态时，两个宾语可以选其中任一个作主语。如果直接宾语被提前作主语，那么间接宾语（一般是人）前要加相应的介词to/for。

　　例：① She gave me a pen.= She gave a pen to me.

　　→I was given a pen by her.

　　→A pen was given to me by her.

　　②My father bought me a new bike.= My father bought a new bike for me.

→I was bought a new bike by my father.

→A new bike was bought for me by my father.

　　⑶由不及物动词（vi）+介词/副词＋宾语的句子改成被动语态时，介词或副词不能丢掉。(前面已举过两例)

　　例：①We should speak to old people politely.

　　→Old people should be spoken to politely ( by us).

　　②He took away the box.

　　→The box was taken away by him.

　　⑷含有宾语补足语的句子改为变动语态。（宾补放在原来位置不变）

　　例：①We call him Xiao Ma.

主 谓　 宾 宾补

　　→He is called Xiao Ma by us.

②He found the book very interesting.

→The book was found very interesting by him.

　　六、没有被动语态的动词：

　　1. 没有被动语态的词， 表示状态或特征的及物动词如 cost, fit, have, suit等没有被动形式，另外，诸如happen = take place, break out(爆发)，break down(坏了) 等不及物动词或短语以及诸如result from(缘于)，belong to, consist of等只用主动语态，而不用被动语态

　　2. 不及物动词或动词短语无被动语态: appear,　die ,disappear, end (vi. 结束), fail, last, lie, remain, sit, spread（传播）, stand, come true, fall asleep, ...

　　3.大多数系动词：be , feel (摸起来)，sound(听起来)，look(看起来)，

smell(闻起来) taste（尝起来）等词无被动语态，它们的主动形式表示被动意义。
