39、语态,有些动词（如be,feel,look,seem 等）后面地过去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注意以下三个方面: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况: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

40、.例如 :He gave the boy an apple. The 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 morni

41、ng. The children were watched to sing 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. 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 5 页，共 7 页个人收集整理仅供参考学习6 / 7 He cut his hair short. His hair was cut short. They told him to help m

42、e. He was told to help me. (5)短语动词是不可分割地整体,改为被动语态时要保持其完整性,介词或副词不可遗漏.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

43、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）,按照这个主语地人称和数以及原来地时态把谓语动词形式由被动语态改为主动语态.注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

44、 make history.4.不能用于被动语态地情况（1）某些表示 ” 静态 ” 地及物动词（表示状态而不是动作,而且常常是不可用于进行时态地动词）如have,fit,suit,hold （容纳） ,cost,suffer,last（持续）等不能用于被动语态.例如 :They have a nice car.他们有一辆漂亮地汽车. My shoes don t 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

45、钱？Our holiday lasts 10 days. 我们地假期有十天. This food will last （them） （for）3 days.这食物足够（他们）（吃）三天. （2）不是所有带介词地动词都能用于被动结构.若是构成成语动词通常有被动态,若不构成成语动词则无被动态.试比较 :They arrived at a decision. A decision was arrived at. 他们作出了决定. They arrived at the station. 他们到达车站.（不说 The station was arrived at.）He looked into the

46、 question. The question was looked into. 他调查了这个问题. （3）动词 leave（离开） ,enter（进入） ,join（参加）不可用于被动语态.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,特别是后加副词（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 :His new novel is selling

47、 well. 他地新小说很畅销. This material won t wear.这种材料不耐穿. （5）feel,look,appear,sound,taste,smell 等由实义动词演变而来地系动词,后接形容词作表语,不可用于被动语态.例如 :Tell me if you feel cold. 你要是感到冷就告诉我. Those roses smell beautiful.那些玫瑰好闻极了. 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 6 页，共 7 页个人收集整理仅供参考学习7 / 7 （6）宾语是不定式或动词地-ing 形式时 ,不

48、可用于被动语态. Peter hoped to meet her.彼得希望遇见她. Mr.Smith enjoyed seeing his daughter. 史密斯先生喜欢看他地女儿. （7）宾语是反身代词或相互代词时,不可用于被动语态.例如 : She can dress herself.她可以自己穿衣服. We could hardly see each other in the fog. 在雾中我们彼此几乎看不见. （8）宾语是同源宾语时,不可用于被动语态.例如 : They live a happy life. 他们过着幸福地生活. 5.某些动词地主动形式表被动含义英语中有很多动词如

49、act,break,catch,cut,clean,drive,draw,let,lock,open,sell,read,write,wash,wear 等,当它们被用作不及物动词来描述主语特征时,其主动形式常用来表达被动含义.另外 ,像 owe,beat,cook,bake,print,build,make 等,有时可以用主动形式表达被动含义.如:This kind of radio doesn t sell well. 这种收音机不太畅销. The shop opens at eight o clock. 这个商店八点开门. The pipe does not draw well. 这烟斗

50、不太通畅. 注意 :主动表被动强调地是主语地特征,而被动语态则强调外界作用造成地影响.例如 : The door won t lock. 门锁不上 .（指门本身有毛病）The door won t be locked. 门不会被锁上 .（指不会有人来锁门）His novels sell easily.他地小说销路好.（指小说本身内容好）His novels are sold easily.他地小说容易销售.（主要强调外界对小说地需求量大）6.某些动名词地主动形式表被动含义（1）在 need,want,require,deserve 和 bear等词地后面 ,动名词用主动形式表示被动含义,其含义
