或

for

。Hetoldheralongstory.

Itisknownthatheisateacher.

Heisknown

thattobeateacher.Alongstorywastoldtoher.

Iwasbought

anewcoat.Anewcoatwasboughtforme.

Shewastoldalongstory.Motherboughtmeanewcoat.3.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。Ifoundhimlyingonthefloor.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。Theflowerssmellsweet.Thefoodtastesnice.2.某些与can’t、won’t

等连用的不及物动词如：move、lock、shut、open

等。Itcan’tmove.Thedoorwon’tshut.

Hewasfoundlyingonthefloor.3.某些可和well、easily

等副词连用的不及物动词如：read、write、wash、clean、draw、burn、cookTheclothwasheswell.Thiskindofricecooksmorequicklythanthatkind.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．Thesearticlesaresoldq
