She was told a long story.Mother bought me a new coat.null3 .复合宾语变为被动语态时,只将宾语变为被动结构中的主语,宾语补足语不变。 I found him lying on the floor. 十个动词的宾语补足语后面是不带to 的动词不定式变为被动语态时要带to 。 有些不及物动词可以表示被动意义,这种不及物动词有下列几种情况： 1.某些连系动词如：smell 、taste 、sound 、feel 等。 The flowers smell sweet. The food tastes nice. 2.某些与can’t 、won’t 等连用的不及物动词如：move 、lock 、shut 、open 等。 It can’t move. The door won’t shut.　　　　　　　　　　　　　　　　He was found lying on the floor.null3.某些可和well 、easily 等副词连用的不及物动词如：read 、write 、wash 、clean 、draw 、burn 、cook The cloth washes well. This kind of rice cooks more quickly than that kind. 被动语态与系表结构的区别 1.被动语态中的过去分词是动词，表动作．系表结构中的过去分词相当于形容词，表状态．前者可用by短语表动作的执行者，后者则一般不用by短语． These articles are sold quickly.(被动) These articles are all sold out.(系表) 系表结构一般只用于一般现在时和一般过去时，被动语态可用于任何时态，系表结构中的过去分词，可被very修饰，被动语态中的过去分词可用much修饰． He was very excited.(系表) He was much excited by the news.(被动)null
