动词的被动语态
动词被动语态
被动语态(the passive voice)英语动词有两种语态：主动语态和被动语态。

)The classroom was cleaned by him yesterday. (主语the classroom 是动作的承受者，是被动语态。
)一．被动语态的构成: be+及物动词的过去分词构成(助动词be必须与主语的人称和数量保持一致，并有时态的变化)。
Eg: The man was fooled by the two boys.It has been decided that the sports meeting would be put off.二．被动语态的用法1. 不知道动作的执行者时用被动语态。

变为主语的若是主动句中的直接宾语在变为间接宾语前则需加介词to 或for。
Eg: The pianist gave the pupils some advice.间接宾语直接宾语→The pupils were given some advice by the pianist.→Some advice was given to the pupils by the pianist.5. 在主动语态句中动词make、have、let、see、watch、hear、feel等后接动词不定式作宾语补足语，动词不定式不加to。

动词的被动语态
被动语态：(1)被动语态定义：被动语态是动词的一种特殊形式,用来说明主语与谓语动词之间的关系。
如果主语是动作的执行者(即某人做某事),便叫主动语态；如果主语是动作的承受者(即某事被做),便叫被动语态。
主动与被动的区别不是词序的区别,而是主语与谓语意义上的区别。
在英语中只有及物动词和一些相当于及物动词的词组才有被动语态的形式。
(2)英语中被动语态由“助动词be +动词的过去分词”构成。
助动词be有时态、人称和(1) 被动语态的用法：①不知道谁是动作的执行者(即不知道谁做)时用被动语态,省略by短语。
如：A manwas killed in the accident.(一个人死于事故)/ This window was broken yesterday.(这扇窗子是昨天被打破的)②不说或者众所周知是谁做时,用被动语态,省略by短语。
如：Rice is also grown inthis place.(这个地方也种水稻)/ A railroad will be built here in three years.(三年之后这里将要修建一条铁路)③强调动作的承受者,句尾加by短语。
如：It was written by Lu Xun.(它(书)是鲁迅写的)/ A pet dog is never killed by its owner.(宠物狗是不会被主人宰杀的)(2)主动语态如何改写为被动语态：(3) 注意点：①“动词+间接宾语+直接宾语”改为被动时,可以用间接宾语做被动句的主语。
如：His teacher gave him a dictionary.→He was given a dictionary by his teacher.(老师给他一本字典→他得到老师一本字典)也可以用直接宾语做被动句的主语,但是需用to或者for引出原句的间接宾语。
如：His teacher gave him a dictionary.→A dictionary was given to．． him by his teacher.(老师给他一本字典→一本字典由老师送给了他)/His father made him a kite.→A kite was made for．．．him by his father.(他的父亲给他做了一个风筝→一个风筝由他的父亲做给了他)②“动词+宾语+动词原形”改为被动时,动词原形前要加to.如：The boss made the poor man work 12 hours a day.→The poor man was made to．． work 12 hours a day.(老板让这个可怜的人一天工作12小时→这个可怜人被迫一天工作12小时)③“动词+…+介词”改为被动时,介词一般在原位不动。
动词的被动语态
英语动词的被动语态一、概念(了解)语态是动词的一种形式，用以说明主语和谓语动词之间的关系。
英语有两种语态:(或执行者)。
speak的动作是由主语many people来执行的eg: Many people speak Chinese.谓语二、构成(掌握)(被动语态的一般疑问式是将助动词或第一个助动词放在主语前面，做出肯定或否定回答时主语后也要用第一个助动词。
)例句解析:The lecture will be made by an artist.The window wasn’t broken by Lisa.Is Mars now being explored by scientists?--Yes, it is. / No, it isn’t.What was stolen last night?When was the school football team set up?Such work can be done in an hour.These books mustn’t be taken out of the reading room.Must the work be handed in by tomorrow?--Yes, it must be. / No, it needn’t be.When can my computer be repaired?What can be reused?三、用法(了解)一般来说，在我们日常生活中，能用主动语态的时候就尽量不去用被动语态。
只有在下列情况中我们才用被动语态:1.不知道动作的执行者是谁。
eg: 1).Some new computers were stolen last night.一些新电脑在昨晚被盗了。
2).This bridge was founded in 1981.这座桥竣工于1981年。
3).The front window in the classroom was broken yesterday. 昨天，教室的前窗被打破。
英语中的被动语态
英语中的被动语态被动语态是英语语法中常用的一种语态形式。
它可以用来表达替换主语的被动语气，使得被动语态句子更加突出动作的接受者或者状态的承受者。
在英语中，被动语态是一种重要的语法结构，对于学习英语的人来说，掌握被动语态的用法非常重要。
一、被动语态的定义及构成方式被动语态是通过在动词前加上助动词“be”的过去分词形式来构成的。
这里的助动词的种类包括“am, are, is, was, were, have(或has), had, will”，并且根据时态的不同将其进行了变化。
例如：一般现在时： am/are/is + 过去分词过去时： was/were + 过去分词现在完成时： have/has + 过去分词将来时： will + be + 过去分词构成被动语态的方式可以用一个简单的公式来表示，即：主语+ 助动词 + 过去分词。
例如：主动： The boy hit the ball.（男孩打了球。
）被动： The ball was hit by the boy.（球被男孩打了。
）二、被动语态的用途1、突出动作的承受者或者状态的承受者被动语态的最主要的用途就是通过替换主语来打出动作的承受者或状态的承受者的差异。
例如：主动： My father bought a new car yesterday.（我爸爸昨天买了一辆新车。
）被动： A new car was bought by my father yesterday.（昨天一辆新车被我爸爸买了。
）2、避免使用主语如果某些情况下，使用主语会使得句子过于重复或者语法不对，那就可以使用被动语态来代替主语。
例如：主动： People say that he is the best student in our school.（人们说他是我们学校最好的学生。
）被动： It is said that he is the best student in our school.（据说他是我们学校最好的学生。

Everyone respects him.He is respected by everyone.被动语态的构成：助动词be +done（时态通过be表现出来）一．各种时态常见的被动语态形式1.一般现在时(am/is/are + done) 如：Y ou are wanted on the phone. 有电话找你。

English is taught in all middle schools. 所有中学都开设英语课。
(2) 没有必要指出动作的执行者是谁。
The meeting was held last week. 会议上周召开了。
(3) 要强调动作的承受者而不是执行者时。

3.被动语态中应注意的几个问题(1) 在被动语态句子中要注意主语与谓语在人称和数方面要保持一致。
(2) 主动语态不能变为被动语态的情况：a．have（有）以及和have构成的短语动词不能用于被动语态b．不及物动词没有动作的承受者，不能用被动语态。
c．主动句的宾语是each other或反身代词时，不能变成被动句的主语。
d．主动句的宾语是不定式或动词的-ing形式时，不能变成被动句的主语。
(3) 注意有时用主动语态表示被动意义的情况。
例如： This kind of cloth washes very well. 这种布很禁洗。
The machine made in China sell well abroad. 中国制造的机器在国外畅销4.被动语态和系表结构的区别动词“be+过去分词”这一结构既可以是被动语态，也可以是系表结构。
这两种结构主要的区别是：被动语态强调动作，系表结构强调状态。
我们还可以通过以下方法来判断：(1) 从形式上来看，被动语态往往接by施动者，而系表结构往往有固定的搭配。
如：be joined to, be connected with, be separated from, be covered with, be interested in, be surprised at, be satisfied with, be concerned about等。
We were surprised at the unexpected news. 听到这个意外消息，我们感到惊讶。
(系表结构)注意：句中有“by+人”时，多用被动语态；而“by+物”时，多属系表结构。
如：The house was surrounded by the police. 这房子被警察包围了。
(被动语态) The house was surrounded by trees. 这房子四周都是树。
(系表结构，表示静止的状态) (2) 从时态上来看，被动语态的be时态要与动作发生的时间一致；而系表结构的be只有一般时或完成时，表示目前或过去的性质或状态。
如：This window was broken by Kate yesterday这窗户是凯特昨天打破的。
(被动语态) This glass is broken. 这块玻璃是破的。
(系表结构，指目前的状态)(3)从句中的状语来看，过去分词前有well, very, quite等副词修饰的是系表结构；若句中有时间、方式或目的状语时，一般为被动语态。
The play is well written. 这剧本写得很好。
(系表结构)The play was written with great care. 这剧本是非常用心地写出来的。
(被动语态，有方式状语) (4)被动语态中的过去分词必须是及物动词，而系表结构中的过去分词可以是gone, fallen, risen 等不及动词。
如下列两句是系表结构：My pen is gone. 我的钢笔不见了。
The sun is risen. 太阳升起来了。
