7、语集合：名词/代词名词性词组以名词/代词为核心，加上前置或后置定语不定式动名词并列结构和从句。2宾语集合：同上。下面依据主动与被动的关系，从宾语集合入手来推导被动句的新鲜形式。例1What are you looking for ?What is beening looked for ? 宾语 主语 例2.He said that he had lived here for a year. 主语 宾语 That he had lived here for a year was saidIt was said that he had lived here for a year形式主语.总之，依据
8、主动与被动的关系和宾语集合元素的不同形式，可以推导出许多不同形式的被动句，除此还应注意以下几个问题：（一）、主动结构表被动意义1.open, lock, write, read, sell, clean, wash, cut, burn, drive,等词用作不及物动词时，它们的主语为物，可以用主动语态表被动意义。例如：This kind of pen writes very smoothly.这种笔写起来很流畅。This kind of shirt sells well.这种样式的衬衫卖的很好。2.look, sound, taste, smell,等系动词主动结构表被动意义。例如：Moon
9、cakes taste delicious.月饼尝起来很好吃。Uniforms look ugly on us.我们穿着制服很难看。3.短语be worth doing中，doing表被动意义。例如：His book is worth reading.他的书值得一读。4.want,/need/require+doing相当于want,/need/require+to be done,to be done表示不定式的被动结构。例如：My bike needs repairing.=My bike needs to be repaired.我的自行车需要修理（二）、不用被动语态的情况1.只有及物动
10、词有被动语态，不及物动词没有被动语态。常见的不及物动词happen, arrive, die, come, go, take place, 等都没有被动语态。例如：Great changes have taken place in our hometown these years.这些年我的家乡发生了巨大的变化。2.主动句的宾语是each other或反身代词时，不能用于被动语态。例如：The man introduced himself as Mr White.(主动语态)那个人自我介绍说他是怀特先生。Himself was introduced as Mr White.(错误)They h
11、elp each other study English.他们互相帮助学习英语。Each other is helped study English.(错误)3.当主动句的谓语动词是表示状态的及物动词时，不能使用被动语态。例如：We will have a meeting.(主动语态)我们打算开会。A meeting will be had by us.(错误)4.主动句的宾语是不定式或doing时，不能用作被动语态中的主语。例如：My mother enjoys watching TV.(主动语态)我的妈妈喜欢看电视。Watching TV is enjoyed by my mother.(
12、错误)He asked to have a try.(主动语态)他请求试一试。To have a try was asked.（错误）（三）、被动语态和系表结构的区别1.被动语态表示以主语为承受者的动作；而系表结构则表示主语的特点或所处的状态。例如：The shop is closed at nine oclock.(动作)这个商店九点关门。The shop is closed today.(状态)这个商店今天不开门。2.系表结构中的过去分词常有固定的介词搭配，被动语态结构中则没有。例如：Miss Wang is satisfied with us.(系表结构)王老师对我们很满意。3.系表结构
13、中的过去分词可以被副词修饰。例如：She is so worried about her mother.( 系表结构)她非常担心她的妈妈。4.系表结构通常只有一般现在时和一般过去时，而被动语态结构可以用于多种时态（四）、省略to的动词不定式的被动语态在主动语态的句子中。一些表示感官或使役意义的动词，如：hear, watch, see, feel, notice, listen to, look at, let, make, have和help等后面的宾语补足语是动词不定式时，主动语态中要用不带to的动词不定式，但当这样的主动语态变为被动语态时，必须把省略to的动词不定式中的to补出来。例如：
14、We often hear her sing in the room.She is often heard to sing in the room.(by us)注意：如果主动句中的感官动词带“v.ing”形式作宾语补足语，则在变为被动语态的时候，v.ing形式不做任何变动。例如：We are listening to him speaking at the meeting.He is being listened speaking at the meeting(by us).、主动语态变为被动语态的方法1.主动语态的宾语变为被动语态的主语。2.主动语态的谓语动词由主动形式变为被动形式。3.主
15、动语态的主语在被动语态中变为介词的宾语（常用的介词为by）。The workers built a new building last year.工人们去年建了一座新楼。（主动语态）A new building was built last year by the workers.一座新楼去年由工人们建起来了。（被动语态）4.带双宾语的动词的主动语态结构的直接宾语或间接宾语都可以变为被动语态的主语He gave me a book on my birthday.在我生日时他给了我一本书。（主动语态）I was given a book on my birthday.在我生日时，我收到了一本书。
16、（被动语态） 或：A book was given to me on my birthday. 在我生日时，有一本书送给了我。（被动语态）5.带复合宾语的动词主动语态变被动语态时，只把宾语变为主语，原来的宾语补足语留在原处。主动语态中，有些动词要求后面用不带to的动词不定式作宾语补足语，若变为被动语态时，要补充还原to。例如：We heard the boy sing in the room.（主动语态）The boy was heard to sing in the room.（被动语态）6.不及物动词没有被动语态，但有的不及物动词后跟一个介词，其作用相当于一个及物动词。His mother
17、 looks after him.他妈妈照顾他。（主动语态）He is looked after by his mother.他由他妈妈照顾。（被动语态）7.某些动词形式上是主动语态，但含有被动的意思，不能变为被动语态结构。The apples sell well.这些苹果很畅销。（主动语态）The coat feels soft.这件衣服摸起来很柔软。三、典型例解1. -Have you ever _ any activities during the summer vacation? -Yes, Ive helped in a disabled childrens home.
