37、成被动语态欢迎下载精品学习资源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

38、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 boy was given an apple. （或 An apple was given to the boy. ）Her father bought her a present. She was boug

39、ht 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 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

40、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.欢迎下载精品学习资源例如 :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,

41、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 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）,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

42、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 ”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 don t fit me. 我地鞋不合适 .My

43、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

44、 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

45、 .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 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 等由实义动词演化而来地系动词,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

46、些玫瑰好闻极了 .（ 6）宾语是不定式或动词地-ing 形式时 ,不行用于被动语态.Peter hoped to meet her.彼得期望遇见她 . Mr.Smith enjoyed seeing his daughter.欢迎下载精品学习资源史密斯先生喜爱看他地女儿.（ 7）宾语是反身代词或相互代词时,不行用于被动语态.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 ,不行用于被动语态 .例如 :They live a happy

47、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许多动词如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点时,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 oclock.这个商店八点开门.The pipe does not draw well.这烟斗不太通畅 .留意 :主动表被动强调地是主语地特点,而被动语态就强调外界作用造成地影响
