英语语法：主动语态变被动语态的一些方法

英语语法：主动语态变被动语态的一些方法主动语态变被动语态的方法1. 基本方法将主动语态的宾语变为被动语态的主语，将主动谓语变为被动谓语(be+过去分词)，将主动语态的主语变为by短语(在被动句中用作状语)：He stole our money.→Our money was stolen by him.【注】(1)若不强调动词执行者，被动语态中的by短语通常能够省略：The house was built in 1978. 这座房子是1978年建的。

(2) 在转变语态时，要注意保持两种语态时态的一致性：The students will study the problem.→The problem will be studied by the students.A friend of ours is repairing the roof.→The roof is being repaired by a friend of ours.2. 双宾动词的被动语态双宾动词即指带双宾语的动词，它们在变为被动语态时，有以下两种情形值得注意：(1) 有些双宾动词(如award, buy, give, leave, lend, offer, pay, show, teach, tell等)在变为被动语态时，既可把间接宾语(指人)变为被动语态的主语，而把直接宾语(指事物)保留下来(称为保留宾语)，也可把直接宾语(指事物) 变为被动语态的主语，而把间接宾语改为介词to 或for引起的状语(到底用to还是for，与所搭配的动词相关)。

2. 有些动词用主动形式表示被动意义。

主动语态变被动语态的几个特例

主动语态变被动语态的几个特例一、含有双宾语的句子变为被动语态时,多数将主动句中的间接宾语变为被动句的主语,直接宾语作保留宾语;也可将直接宾语变为主语,间接宾语作保留宾语,但这时保留宾语前多加介词to或for。

如: He gave me a new watch.→1) I was given a new watch.2) A new watch was given to me.二、含有复合宾语且宾语补足语是名词的句子变为被动语态时,只能将主动句中的宾语变为被动句中的主语,宾补不可变为主语。

如: They call me Jim. →I am called Jim.(不可说:Jim is called me.)三、主语为疑问词的疑问句变为被动语态时,用“By+疑问词(宾格)”置于句首。

如:Who broke the glass? →By whom was the glass broken?四、祈使句变为被动语态时,要改为“Let +原宾语+be+过去分词”。

如:Close the window. →Let the window be closed.五、带宾语从句的复合句变为被动语态时,多用it作形式主语置于句首,原宾语从句成为真正主语(从句),从句中也需用被动语态。

如: People said that Lin Feng could take good care of the baby. →It was said that the baby could be taken good care of by Lin Feng.六、含有谓语动词know的主动句变为被动语态时,不用by短语,需by改为to。

如:We all know the scientist. →The scientist is known to us all.七、no one、nobody等否定代词作主语的句子变为被动语态时,谓语动词用否定式,不再用原主语,但可加上by anyone、by anybody等短语。

语法被动语态和主动语态的转换

语法被动语态和主动语态的转换语法被动语态和主动语态在英语中是非常常见的语法结构，它们的转换能够给语句带来不同的语气和意义。

对于学习英语的人来说，掌握被动和主动的转换能力是非常重要的。

本文将探讨语法被动语态和主动语态之间的转换方法和注意事项。

一、被动语态和主动语态的定义和用法被动语态是指句子的动作的承受者成为主语，而动作的执行者则成为句子的宾语。

举个例子，"The book was written by him."（这本书是他写的）这个句子中，"The book"（这本书）是动作的承受者，而"him"（他）则是动作的执行者。

主动语态是指句子的执行者成为主语，而动作的承受者则成为句子的宾语。

举个例子，"He wrote the book."（他写了这本书）这个句子中，"He"（他）是动作的执行者，而"the book"（这本书）则是动作的承受者。

被动语态的使用场景主要有以下几个方面：1. 承受者重要程度高于执行者；2. 执行者不明确或无需指出；3. 强调动作的执行过程。

主动语态的使用场景主要有以下几个方面：1. 重点强调执行者；2. 执行者比承受者更重要；3. 强调动作的完成过程。

二、主动语态转换为被动语态的方法：1. 将主动语态句子的宾语变为被动语态句子的主语。

例子：She drinks coffee.(主动语态) – Coffee is drunk by her.(被动语态)2. 将主动语态句子的主语变为被动语态句子的宾语。

例子：They play basketball.(主动语态) – Basketball is played by them.(被动语态)3. 将主动语态句子的谓语动词变为被动语态句子的谓语动词的过去分词形式。

例子：She writes a letter.(主动语态) – A letter is written by her.(被动语态)4. 在被动语态句子中添加"by"短语，指明动作的执行者。

如何将主动语态转换成被动语态

如何将主动语态转换成被动语态编者按：将主动语态转换成被动语态时将主动句的宾语变成被动句的主语，原来的主语药用by引出来。

下面小编就来带你一起学习下主动语态转换成被动语态的3个要求吧。

将主动语态转换成被动语态有3个要求：1.将主动句的宾语变成被动句的主语。

2.将谓语改成被动式：be+过去分词。

3.原句的主语用by引出来，放在谓语后面。

如果不需要，可以省去。

主动句：Class 3 defeated Class 1.三班打几了一班。

被动句：Class 1 was defeated by Class 3.一班被三班打败了。

注意点：1.对于有双宾语的主动句，可以将当中任何一个宾语移到前面作主语，另一个宾语留在原来的位置上：主动句：Father gave me a watch.爸爸给了我一块表。

被动句：I was given a watch by father.我被我爸送了一只表。

A watch was given (to) me by father.一只表被我爸送给我。

主动句：She passed him a phone.他递给他一个手机。

被动句：He was passed a phone.他递给一个手机。

A phone was passed (to) him by her.一只手机被她递给他。

2.在把带宾补的主动句变成被动句时，宾补的位置不动，这时的宾补其实是补充说明主语的主语补足语了。

例如：主动句：We elected Jim monitor.我们选举杰姆当班长。

被动句：Jim was elected monitor by us.杰姆被我们选举为班长。

特别注意：如果句子中含有不带to的不定式作宾语补语，变成被动句时，必须把不定式符号to加上：主动句：His father made him work hard.他父亲迫使他下功夫。

被动句：√He was made to work hard by his father.他被他父亲逼迫去下功夫。

主动句变被动句的几种特殊类型

主动句变被动句的几种特殊类型（1）主动语态中有些感官动词（如：hear, see, watch, notice等）后用不带to的不定式作宾语补足语，变为被动语态时，要把不定式符号to还原，即：hear(see) sb. do sth.→sb. be heard(seen) to do sth.。

We often hear the girl sing in her room in the evening.→The girl is often heard to sing in her room in the evening by us.晚上我们经常听到那个女孩在她的房间里唱歌。

（2）主动语态中有些使役动词（如：make, let等）后用不带to的不定式作宾语补足语，变为被动语态时，同样要把不定式符号to还原，即：make sb. do sth.→sb. be made to do sth.。

主动结构表示被动意义的情况：（1）动词open, read, sell, write等作不及物动词, 且它们的主语为物时。

如：The pen writes well. 这支钢笔很好用。

（2）某些连系动词（如smell, look, taste, feel, sound等）描述某物特性时。

如：This kind of flower smells sweet. 这种花闻起来很香。

（3）一些动词的主动形式表被动意义。

①be worth doing中,doing表示被动意义。

如：This movie is worth watching. 这部电影值得一看。

②“need/require+doing”相当于“need/require+to be done”, to be done 是不定式的被动结构。

如：Your car needs washing.= Your car needs tobe washed. 你的汽车该洗了。

一、主动语态改成被动语态方法把主动语态改为被动语态非常简单，可以遵循以下几个步骤：1. 将主动语态的宾语作被动语态的主语;2. 谓语动词变为“be+及物动词的过去分词”，并通过be的变化来表达出不同的时态;3主动语态的主语变为介词by的宾语，组成介词短语放在被动结构中的谓语动词之后。

(有时by的短语可以省略);例：1. Bruce writes a letter every week. →A letter is written by Bruce every week.二、被动语态的用法：1. 一般现在时的被动语态构成：is / am / are + 及物动词的过去分词 Our classroom is cleaned everyday.2. 一般过去时的被动语态构成：was / were + 及物动词的过去分词 A new shop was built last year.3. 现在完成时的被动语态构成：has / have + been + 及物动词的过去分词This book has been translated into many languages.4. 一般将来时的被动语态构成：will+ be + 及物动词的过去分词 Many more trees will be planted next year.5. 含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词Young trees must be watered often.6. 现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词 Uncle Wang is mending my bike no w.→ My bike is being repaired by Tom now.7. 不定式的被动语态：to + be + 及物动词的过去分词 There are two books to be read. → There are twenty more trees to be planted.三、使用被动语态应注意的几个问题：1. 不及物动词无被动语态。

句型变换改变主动语态为被动语态

句型变换改变主动语态为被动语态句型变换：改变主动语态为被动语态在英语中，句子的语态可以分为主动语态和被动语态。

主动语态强调动作的执行者，而被动语态则强调动作的接受者或受事者。

在进行句型变换时，我们需要改变动词的形式以及重组句子结构。

被动语态的构成方式为：be动词 + 过去分词（动词的第三形式）。

下面以一些常见的句型为例，来演示如何将主动语态变为被动语态。

一、直接宾语变换主动语态：主语 + 动词 + 宾语被动语态：宾语 + be动词 + 过去分词 +（by + 主语）1. He eats an apple.被动语态：An apple is eaten by him.2. They played basketball.被动语态：Basketball was played by them.二、间接宾语变换主动语态：主语 + 动词 + 间接宾语 + 直接宾语被动语态：间接宾语 + be动词 + 过去分词 + direct object（by + 主语）1. She gave me a book.被动语态：I was given a book by her.2. They showed us the way.被动语态：We were shown the way by them.三、不带宾语的及物动词变换主动语态：主语 + 不及物动词被动语态：be动词 + 过去分词 +（by + 主语）1. He sleeps.被动语态：He is slept.2. The flowers bloom.被动语态：The flowers are bloomed.四、双宾语变换主动语态：主语 + 动词 + 间接宾语 + 直接宾语被动语态：间接宾语 + be动词 + 过去分词 + direct object（by + 主语）1. She gave me a present.被动语态：I was given a present by her.2. He showed them the pictures.被动语态：They were shown the pictures by him.需要注意的是，在被动语态中，如果句子中有by短语，该短语通常用于表示动作的执行者或者强调执行者的重要性。
