3.不特别强调动作执行者时，by短语(即by和后面的宾语)一般可以省略

1.带双宾语的句子有两种改法: 一般情况 下把指人的宾语作为被动句的主语.当把 直接宾语物作为主语时，要加介词to,for 1.We call Mr. Smith a living Lei Feng. is called Mr. Smith_________ a living Lei Feng (by us). 2.Tom

’s father bought him a book. was bought He _____________ a book (by his father)

was bought to A book_________him (by his father)

如：give be given to 此类动词有： pass, show, send… buy be bought for 此类动词还有：draw,make, cook,

mend

2.感官动词(hear, see, watch, feel, notice 等)和使役动词(let ,make have等)在主动语态 中后接不带to的动词不定式,但是改为被动语态 时, 把to加在动词原形之前. They made the boys work 12 hours a day.

4 短语动词的被动语态 I can take good care of the baby. The baby can be taken good care of. We should speak to the old politely. The old should be spoken to politely.

stop , taste 在句中是不及物动词，后面不能直接带宾语，因此 不能变为被动语态。
