The boy was given an apple.<或 An apple was given to the boy）.可编辑资料 - - - 欢迎下载精品_精品资料_Her father bought her a present. She was bought a present by her father.<或 A present was bought for her by her father.）3>不带 to 的动词不定式作宾语补足语的主动语态,改为被动语态时不定式前要加 to.例如:They watched the children sing that morning. The children were watched to sing that morning.4>带复合宾语的动词在改为被动语态时 ,一般把主动语态的宾语改为主语 ,宾语补足语在被动语态中作主语补足语.例如:We call him Xiao Wang. He is called Xiao Wang. He cut his hair short. His hair was cut short.They told him to help me. He was told to help me.5>短语动词是不行分割的整体 ,改为被动语态时要保持其完整性 ,介词或副词不行遗漏.例如 :We must take good care of the young trees. The young trees must be taken good care of.6>含有宾语从句的主动结构变为被动结构时,通常用 it 作为被动结构的先行主语 ,从句放在句子后面 ;也可采纳另一种形式.可以这样转换为被动结构的动词有 know,say,believe,find,think,report等.例如 :People believe that he is ill. It is believed that he is ill.<或:He is believed to be ill.）3. 被动语态改为主动语态的方法可编辑资料 - - - 欢迎下载精品_精品资料_被动语态中介词 by 后的宾语改为主动语态中的主语 <或按题意要求确定主语） ,根据这个主语的人称和数以及原先的时态把谓语动词形式由被动语态改为主动语态.留意在主动语态中有的动词要求不带 to 的动词不定式作宾语补足语,此时要把被动语态中的to 去掉.被动语态的主语用来作主动语态的宾语.例如:History is made by the people.The people make history.4. 不能用于被动语态的情形<1 ）某些表示 ”静态 ”的及物动词 <表示状态而不是动作 ,而且经常 是 不 可 用 于 进 行 时 态 的 动 词 ） 如 have,fit,suit,hold< 容纳） ,cost,suffer,last<连续）等不能用于被动语态.例如 :They have a nice car他. 们有一辆美丽的汽车.My shoes dont fit me. 我的鞋不合适.My brain cant hold so much information at one time.我的脑子一下子记不住这么多资料.How much What does it cost？这值多少钱？Our holiday lasts 10 days我. 们的假期有十天.This food willlast<them） <for ） 3 days.这食物足够 <他们） <吃）三天.<2）不是全部带介词的动词都能用于被动结构.如是构成成语动词通常有被动态 ,如不构成成语动词就无被动态.试比较 :They arrived at a decision. A decision was arrived at他.们作出了打算.可编辑资料 - - - 欢迎下载精品_精品资料_They arrived at the station.他们到达车站. <不说 The station was arrived at）.He looked into the question.The question was looked into.他调查了这个问题.<3）动词 leave<离开） ,enter<进入） ,join< 参与）不行用于被动语态.例如 :The car left the road and hit a tree车. 子离开了道路 ,撞上了树.<4 ）某些及物动词可作不及物动词用 , 特殊是后加副词 < 如well,easily 等） 时 . 主 动语 态有 被动含义 , 这类 动词 常见的 有sell,write,wear,wash,cook,open,close,lock,read,record等.例如 :His new novel is selling well. 他的新小说很畅销.This material wont wear.这种材料不耐穿.<5 ） feel,look,appear,sound,taste,smell等由实义动词演化而来的系动词,后接形容词作表语 ,不行用于被动语态.例如 :Tell me if you feel cold. 你要是感到冷就告知我.Those roses smell beautiful那. 些玫瑰好闻极了.<6）宾语是不定式或动词的
