被动语态(讲解)(DOC)
By-Bevis 被动语态By-Bevis英语中语态是动词的一种形式，用来说明主语和谓语动词之间的关系。
分为主动语态、被动语态两种。
即主语“做某事”（主动）或者主语“被做某事”（被动）。
汉语中所说的“课桌被修好了”，“房子是由工人们建的”这样的在动词前面加个“被”字、“由”字的句就是一种被动语态的句型，在英文中则用动词的被动语态形式表示。
一、语态的种类：语态定义主动语态表示主语是动作的执行者被动语态表示主语是动作的承受着，即动作发生的对象例句主动：Lily asked the question. 我问了这个问题被动：The question was asked by Lily. 这个问题是由我问的二、被动语态的基本构成形式：Be动词+ 动词的过去分词形式（由两部分构成）三、被动语态的时态结构变化（主动语态以动词ask 为例）时态结构、例句一般现在时They ask a question（主动）肯定式：否定式：疑问式：主语+am/is/are+动词过去分词+其它+by+介词宾语A question is asked by them.主语+am/is/are+not+动词过去分词+其他++by+介词宾语A question is not asked by them.Am/is/are+主语+动词过去分词+其他+by+介词宾语Is a question asked by them?一般过去时They asked a question yesterday肯定式：否定式：疑问式：主语+was/were+动词过去分词+其它+by+介词宾语A question was asked yesterday by them主语+ was/were+not+动词过去分词+其它+by+介词宾语A question was not asked yesterday by themWas/were+主语+动词过去分词+其它+by+介词宾语Was a question asked yesterday by them?一般将来时They will ask a question tomorrow肯定式：否定式：疑问式: 主语+ will + be + 动词过去分词+ 其它+by+介词宾语A question will be asked tomorrow by them主语+ will + not + be + 动词过去分词+ 其它+by+介词宾语A question will not be asked tomorrow by themWill + 主语+ be + 动词过去分词+ 其它+by+介词宾语Will a question be asked tomorrow by them?过去将来时They would asked a question the next day肯定式：否定式：主语+ would + be + 动词过去分词+ 其它+by+介词宾语A question would be asked the next day by them主语+ would + not + be + 动词过去分词+ 其它+by+介词宾语A question would not be asked the next day by them疑问式：Would + 主语+ be + 动词过去分词+ 其它+by+介词宾语Would a question be asked the next day by them?现在进行时They are asking a question now肯定式：否定式：疑问式：主语+ am/is/are + being +动词过去分词+其它+by+介词宾语A question is being asked now by them主语+am/is/are+being+not+动词过去分词+其它+by+介词宾语A question is being not asked now by them.Am/Is/Are+主语+being+动词过去分词+其它+by+介词宾语Is a question being asked now by them?过去进行时They were asking a question at that time肯定式：否定式：疑问式：主语+was/were+being+动词过去分词+其它+by+介词宾语A question was being asked at that time by them主语+was/were+being+动词过去分词+其它+by+介词宾语A question was being asked at that time by themWas/were+主语+being+动词过去分词+其它+by+介词宾语Was a question being asked at that time by them?现在完成时They have asked a question肯定式：否定式：疑问式：主语+have/has +been+动词过去分词+其它+by+介词宾语A question has been asked by them主语+have/has+not+been+动词过去分词+其它+by+介词宾语A question has not been asked by themHave/Has+主语+been+动词过去分词+其它+by+介词宾语Has a question been asked by them？过去完成时They had asked a question肯定式：否定式：疑问式：主语+had+been+动词过去分词+其它+by+介词宾语A question had been asked by them主语+ had+not+been+动词过去分词+其它+by+介词宾语A question had not been asked by themHad+主语+been+动词过去分词+其它+by+介词宾语Had aquestion been asked by them?情态动词They can ask a question肯定式：否定式：疑问式：主语+情态动词+be+动词过去分词+其它+by+介词宾语A question can be asked by them主语+情态动词+not+be+动词过去分词+其它+by+介词宾语A question can not be asked by them情态动词+主语+ +be+动词过去分词+其它+by+介词宾语Can a question be asked by them?be going to They are going to ask a question肯定式：否定式：疑问式：主语+be going to+be+动词过去分词+其它+by+介词宾语A question is going to be asked by them主语+ be going to +be+动词过去分词+其它+by+介词宾语A question is not going to be asked by themBe going to +主语+ +be+动词过去分词+其它+by+介词宾语Is a question going to be asked by them?练习：用横线划出下列句子的主语、谓语动词、宾语，并改成被动语态1.Students clean the classroom every day2.

(完整)初中英语被动语态讲解
初中英语被动语态解说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的履行者，被动语态表示主语是动作的蒙受者。
一、被动语态的组成英语动词的被动语态由助动词be+及物动词的过去分词组成。
助动词be一定与主语的人称和数目保持一致，态的变化。
比如：The man was fooled by the two boys.The book has been translated into several languages.二、被动语态的用法（ 1）动作的履行者不知道是谁或难以说明经常用被动语态。
比如：并有时Street lights are often turned on at six in winter.The new test book will be used next term.（ 2）当动作的蒙受者比起动作的履行者来说更能惹起人们的关怀而需要加以重申时，要用被动语态。
比如：This kind of bicycle is not sold in our shop.The thief was caught by a policeman yesterday.（ 3）含有双宾语的句子，主动句中的间接宾语或许直接宾语都可变为被动语态中的一个主语，另一个保存不变。
变为主语的假如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。
比如： The pianist gave the pupils( 间接宾语 )some advice(直接宾语 )→The pupils were given some advice by the pianist. → Some advice was given to the pupils by the pianist.(4)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。

(完整)被动语态讲解
被动语态讲解一、总述:英语动词有两种语态，即主动语态（The Active Voice)和被动语态（The Passive Voice)。

They will build a new bridge over the river. (主动）A new bridge will be built over the river. (被动)汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用：助动词be + 及物动词的过去分词构成。
二、被动语态的形式1) 常用时态的被动语态的构成:被动语态的基本形式为助动词be + 及物动词的过去分词，即be done。
被动语态的时态、人称和数的变化主要体现在be的变化上，其形式与系动词be的变化形式完全一样.以give 为例，列表如下：一般现在时：am / is / are + given一般过去时：was / were +given一般将来时：shall / will +be+ given过去进行时：was / were + being + given现在进行时：am / is / are + being + given过去完成时：had + been + given现在完成时：have / has + been + given将来完成时：shall / will + have been + given过去将来时： should / would +be+ given现在完成进行时：have/has been being done含情态动词的被动语态：情态动词＋be done［注]被动语态没有将来进行时和过去将来进行时.2）被动语态的否定式：在第一个助动词后加not构成.Russian is not taught in our school. 我们学校不教俄语。
3)被动语态的疑问式：把第一个助动词提到主语之前,句尾加问号构成。
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。

4.一般将来时的被动语态构成为：will + be + 及物动词的过去分词。
例如：我们城市将会建造一家新医院。
明年将会种更多的树。

动词被动语态讲解
模块八动词的被动语态(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、人称和数的变化。
被动语态后的by短语有时可(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 man was 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 in this 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：+受者)+(动作的承受者) (be +过去分词) (动作的执行者)(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。

词be有时态、人称和数的变化。
被动语态后的by短语有时可
(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 man was 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 in this 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：
+
受者)
+
(动作的承受者) (be +过去分词) (动作的执行者)
(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。
如：The girl takes good care of．． her little brother.
→The girl’s little brother is taken good care of．． by her.(女孩照
顾小弟弟→女孩的小弟弟由她照顾着)
④“be+过去分词”未必表示被动语态,而可能是系表结构。
如：He is pleased / worried / tired /…….(系表)(他高兴/焦虑/疲劳……)
He was hit / knocked down / told / shot / …….(被动)(他被击中/撞倒/关照/射中……)
1、含双宾语的主动语态的转换：可用其中任何一个宾语作主语，但用直接宾语作主语时，被动语态句子中的原间接宾语前要加必要的介词(多数加to, 个别加for)。
如：(1)My grandpa gave me a ball as the birthday present.
→I was given a ball as the birthday present (by my grandpa).
或→A ball was given to me as the birthday present.
(2)His aunt bought him a dictionary.
→He was bought a dictionary by his aunt.
或→A dictionary was bought for him by his aunt.
2、含复合宾语的主动语态的转换：变为被动语态时，宾补要保留，但当宾补是不带to的不定式时，必须加上to.
如：(1) They call him Lao Zhang.
→He is called Lao Zhang.
(2)I often hear her sing English songs.

注：被动语态的记忆口诀
被动语态强调“宾”，用be加上“过去分”。
“be”要随着主语变，人称时态要弄准。
“行为对象”作主语，逻辑主语“by”来引。
原句若是双宾语，一变“主”来一保“宾”。
“间宾”要把主语变，原来“直宾”还是“宾”。
直宾”要把主语变，“间宾”前加“to”最称心。
唯有原“宾”是“复合”，只有变宾要当心。
原句“宾补”变“主补”，位置不必挪寸分。
情态动词变“被动”，情态加be加过分。
如若“情态”后带to，变后有to才弄准。
“短语动词”变“被动”，相当“及物”莫疑心。
不过其后“介”或“副”，变后还得要承认。
