被动语态的转换步骤：当主动语态变为被动语态时，通常要经过四步:1.先确定主动句的主、谓、宾，找出其谓语动词。
2.把主动句中谓语动词后面的宾语变成被动句的主语,若宾语是人称代词时，应把宾格变为主格3。
把主动句中的谓语动词变为“be+及物动词的过去分词"，但时态不能改变。
4。
把主动句中谓语动词前面的主语变为被动句中介词by的宾语(没必要说出动作的执行者时可略去“by+宾语”）,若主语是人称代词时，应把主格变成宾格。

初中英语语法——被动语态用法总结归纳
初中英语语法——被动语态用法总结归纳被动语态是英语语法中的重要部分，学好被动语态的用法可以帮助学生更准确地理解和使用英语。
下面是被动语态用法的详细总结归纳。
1.被动语态的构成：被动语态由“助动词be+过去分词”构成，根据时态的不同，助动词be的形式也会发生变化。
如：- 一般现在时：am/is/are + 过去分词- 一般过去时：was/were + 过去分词- 一般将来时：will be + 过去分词- 现在进行时：am/is/are being + 过去分词- 过去进行时：was/were being + 过去分词- 现在完成时：have/has been + 过去分词- 过去完成时：had been + 过去分词2.被动语态的用法：被动语态用来强调动作的承受者（主语）而不是执行者，并且常用于以下情景：2.1当我们不知道或不关心动作的执行者时。
例如：The cake was eaten.（蛋糕被吃了。
）2.2当动作的执行者已知，但我们要强调动作的承受者时。
例如：The house was built by my grandfather.（这座房子是我爷爷建的。
）2.3当我们要避免使用第一人称或第二人称时。
例如：Mistakes were made.（犯了错误。
）3.被动语态的注意事项：在使用被动语态时，需要注意以下几点：3.1表示动作的动词要用过去分词形式。
过去分词的形式有规律变化和不规律变化两种。
如：- 规律变化：原形 + ed，例如：played, watched, called- 不规律变化：需要记忆，例如：born, written, eaten3.2被动句的主语是动作的承受者，通常出现在句子的前面。
如：- 主动语态：I cooked dinner.（我做了晚饭。
）- 被动语态：Dinner was cooked by me.（晚饭是我做的。
）3.3 不及物动词不能构成被动语态。
不及物动词没有宾语，因此不能强调动作的承受者。

初中英语语法——被动语态用法总结归纳
初中英语语法——被动语态用法总结归纳被动语态是英语语法中的一种重要的句型结构，用来表示主语是动作的承受者，或者是主语被动地接受了其中一种行为或影响。
在被动语态中，动作的执行者通常不被说明，而动作的接受者（主语）成为句子的重点。
被动语态的结构是：“be”动词的适当形式 + 过去分词被动语态的时态、语态和主动语态一样，即可以变换时态（一般现在时、一般过去时、一般将来时等）和语态（进行时、完成时等）。
下面对被动语态的几个方面进行总结归纳。
1.一般现在时被动语态：一般现在时被动语态的结构是：“am/is/are”（be动词的适当形式）+ 过去分词例如：- 主动语态：They make cars.- 被动语态：Cars are made by them.2.一般过去时被动语态：一般过去时被动语态的结构是：“was/were”（be动词的适当形式）+ 过去分词例如：- 主动语态：She cooked dinner.- 被动语态：Dinner was cooked by her.3.一般将来时被动语态：一般将来时被动语态的结构是：“will be”（be动词的适当形式）+ 过去分词例如：- 主动语态：You will clean the room.- 被动语态：The room will be cleaned by you.4.进行时被动语态：进行时被动语态的结构是：“am/is/are being”（be动词的适当形式）+ 过去分词例如：- 主动语态：They are painting the wall.- 被动语态：The wall is being painted by them.5.完成时被动语态：完成时被动语态的结构是：“has/have been”（be动词的适当形式）+ 过去分词例如：- 主动语态：She has written a book.- 被动语态：A book has been written by her.需要注意的是，被动语态的主语通常不是动作的执行者，所以经常用于下面几种情况：-当动作的执行者不得而知或不重要时，使用被动语态。

被动语态(be done)
一、概况：
英语的语态是通过动词形式的变化表现出来的。
英语中有两种语态：主动语态和被动语态。
主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者，即行为动作的对象。
Eg: Many people speak Chinese.
Chinese is spoken by many people.
二、被动语态的构成：
1. 一般现在时/过去时：be done
2. 一般将来时：will be done/ am/ is/ are going to be done
过去将来时：would be done/ was/ were going to be done
3. 进行时：be being done （being此时不发生任何变化）
4. 完成时：have/ has/ had been done （been此时不发生任何变化）
5. 含有情态动词的：情态动词+ be done （be此时不发生任何变化）
三、被动语态的用法
1. 不知道或没有必要说明动作的执行者是谁
Eg: Some new computers were stolen last night.
This bridge was founded in 1981.
2. 强调动作的承受者，而不强调动作的执行者。
Eg: The glass was broken by Mike.
This book was written by him.
Your homework must be finished on time.
四、主动语态变被动语态的方法
1. 把主动语态的宾语变为被动语态的主语。
2. 把谓语变成被动结构（be＋过去分词），其中被动结构中的done由句中的实义动词变化而来（根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式）
3. 把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。
Eg: All the people laughed at him. He was laughed at by all people.
They make the bikes in the factory. The bikes are made by them in the factory.
My brother was doing his homework. The homework was being done by my brother.
I have finished the difficult project. The difficult has been finished by me.
We can repair this watch in two days. This watch can be repaired in two days.
They should do it at once. It should be done at once.
五、特殊情况：
1. 含有双宾语的句子变为被动语态时，其中一个宾语作句子的主语，另一个保持不变。
变为主语的如果是“直宾”，间宾钱需加prep. to或for
Eg: The pianist gave the pupils some advice. The pupils were given some advice by the pianist.
Some advice was given to the pupils by the pianist.
2. 在主动语态中，动词make, let, have ,see, watch, hear, feel等后接动词不定式作宾补时，需省略to，
但变成被动语态时，后面的to需加起来
Eg: The boss made them work ten hours a day. They were made to work ten hours a day.
A boy saw him enter the house. He was seen to enter the house.
六、不能用于被动语态的词或短语：
1.系动词、不及物动词（短语）无被动语态，常见的有：appear; die; end(vi.结束）；fail; happen; take place; break out; come true等
2.不能用于被动语态的及物动词（短语）常见的有：have; own; belong to; cost; notice; watch; arrive at/in等。
