38、s.2.Go over the passive voice in different tenses and by+-ing form.Reference for Teaching Grammar 被动语态1.被动语态地构成英语动词有两种语态 :主动语态和被动语态 .主动语态表示主语是动作地执行者 ,被动语态表示主语是动作地承担者 . 由于不及物动词不能带宾语 ,故无被动语态 ,只有及物动词或相当于及物动词地动词短语才有被动语态 ,其基本构成方式是” 助动词 be过去分词 ” .留意 :” be过去分词 ”结构不肯定都是被动语态 ,有些动词（如 be,feel,look,seem 等）后面地过去

39、分词已转化为形容词 ,用作表语表示状态 .例如 :The glass is broken.杯子破了 . 2.主动语态改被动语态地方法1将主动语态改为被动语态应留意以下三个方面:将主动语态地宾语改为被动语态地主语 ;将主动语态地谓语动词改为” be过去分词 ”结构 ;将主动语态地主语改为介词 by之后地宾语 ,放在谓语动词之后（有时可省略）.2含直接宾语和间接宾语地主动语态改为被动语态时有两种情形 :把间接宾语改为被动语态地主语 ,直接宾语仍保留原位 ;把直接宾语改为主动语态地主语 ,此时 ,间接宾语前要加介词 to 或 for.例如 :He gave the boy an apple. The

40、 boy was given an apple.（或 An apple was given to the boy. ）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 地动词不定式作宾语补足语地主动语态,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 sin

41、g that morning. 4带复合宾语地动词在改为被动语态时,一般把主动语态地宾语改为主语,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地整体,改为被动语态时要保持其完整性,介词或副词不行遗漏.5 / 7 名师归纳总结 - - - - - - -第 5 页,共 7 页精选学习资料 -

42、- - - - - - - - 个人收集整理 仅供参考学习例如 : We must take good care of the young trees. The young trees must be taken good care of. 6含有宾语从句地主动结构变为被动结构时,通常用it 作为被动结构地先行主语,从句放 在 句 子 后 面 ; 也 可 采 用 另 一 种 形 式 . 可 以 这 样 转 换 为 被 动 结 构 地 动 词 有know,say,believe,find,think,report 等.例如 :People believe that he is ill. It i

43、s believed that he is ill. （或 :He is believed to be ill. ）3.被动语态改为主动语态地方法被动语态中介词 by 后地宾语改为主动语态中地主语（或按题意要求确定主语）,根据这个主语地人称和数以及原先地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地动词要求不带 to 地动词不定式作宾语补足语 ,此时要把被动语态中地 to 去掉 .被动语态地主语用来作主动语态地宾语 .例如 :History is made by the people. The people make history.4.不能用于被动语态地情形（1）某些表示

44、” 静态 ” 地及物动词（表示状态而不是动作,而且经常是不行用于进行时态地动词）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.他们有一辆美丽地汽车 . My shoes dont fit me. 我地鞋不合适 . My brain can t hold so much information at one time.我地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. 我们地

45、假期有十天 . This food will last （them） （for）3 days.这食物足够（他们）（吃）三天 . （2）不是全部带介词地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 . 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 ,这类动词常见地有sell,write,wear,wash,cook,open,close,lock,read,record 等.例如 :
