She was told a long story.A long story was told to her.Mother bought me a new coat.I was bought a new coat.A new coat was bought for me. 、“主谓宾宾补”句型变为被动结构时，只将句中的宾语变为被动句中的主语，宾补不变。如：I found him lying on the floor.He was found lying on the floor.We call her Rose.She is called Rose.、当主动句中有see/hear/feel/watch/notice/make/ have sb do sth 变为被动句时，do 前要加上to .如：I often hear him sing.He is often heard to sing.They made the boy go to bed early.The boy was made to go to bed early三、使用被动语态时应注意：有些动词形式上主动，意义上是被动，用时特别要小心。、可和well等连用的及物动词。 My pen writes well. 我的笔好使。The cloth washes well. 这个料子耐洗。The poem reads smoothly. 这首诗读起来很流畅。、be + 形 to do sth.The story is interesting to read.The wine is nice to drink.、某些连系动词 The flowers smell sweet.这 花 儿 很 香 。 The food tastes nice.这 食 物 味 道 好 。、下列词不用被动形式：last(持续), have(有)， wish, let, take part in, break out(爆发),happen. I have two brothers. I didnt let him go home.Step 4 practice (Exercises)一、将下列句子改为被动语态1. Many people speak English in the U.S.A. English is spoken by many people in the U.S.A.2.
