初中阶段，学生需要掌握被动语态的基本用法，并能够正确地分类和运用。
本文将对初中英语知识点中的被动语态进行归纳，并进行适当的分类，以帮助学生更好地掌握被动语态的用法。
一、基本用法被动语态的基本结构是“be + 过去分词”，其中“be”是根据时态和情态动词的要求进行变换，过去分词则是动词的过去式或者第三人称单数形式。
被动语态常用于以下情况：1. 当不知道或者不关心动作的执行者时，可以使用被动语态。
例如：- The car was repaired yesterday. （这辆车昨天被修理了。

初中英语【被动语态】用法及易错点详细讲解所谓“被动语态”，相当于中文中常说的“被……”、“由……”的句式，如：“他的自行车被偷了”、“这座楼房是由他们建造的。
”一、主动语态和被动语态的概念1）He opened the door. 他开了门。
以上例句是一个主动句，主语是动作的执行者/发出者2）The door was opened by him. 门被开了。
第二个例句是一个被动句，主语是动作的承受者汉语中表示被动的词：被…/ 由…/ 受…/ 给…英语中表被动用：be+过去分词构成二、被动语态的结构及用法1）被动语态的几种句型肯定句：主语+be+及物动词的过去分词+（by）eg: My phone was made in China.否定句：主语+be not+过去分词+（by）eg: My phone wasn’t made in China.一般疑问句：Be+主语+过去分词+（by）？eg: Was your phone made in China?特殊疑问句：特殊疑问词+be+主语+过去分词+（by）?第 1 / 26 页eg: Where was your phone made?2）不同时态中的被动语态3）被动语态的用法当不知道或没有必要指出动作的执行者时，常用被动语态，这时往往不用by 短语。
The front window in the classroom was broken yesterday.昨天，教室的前窗被打破了。
(不知谁打破的)They have been poorly paid.他们的工资太低。
(没必要指出工资是谁付的)突出或强调动作的承受者，如果需要说出动作的执行者，用by短语。
These books are written especially for children.这些书是专门为孩子们写的。
(强调的是“这些书”)三、主动语态变被动语态1）一般情况下主动语态变被动语态主动句：He closed the door.第 2 / 26 页变被动句：The door was closed by him.口诀：宾变主，主变宾，谓变be done, 时不变，数格必须随被变。
初中英语被动语态
一、概念：
表示动作与主语之间是关系的句子是被动语态。
二、被动语态的构成
被动语态由“＋”构成。
人称、数和时态的变化是通过的变化表现出来的。
三、几种常见时态被动语态的构成：“被动语态字变，跟后面”
一般现在时：
一般过去时：
一般将来时：
现在完成时：
含有情态动词：
四、主动语态变被动语态的方法
(1)把主动语态的变为被动语态的。
(2)把变成被动结构( )
(3)把主动语态中的放在介词by之后作宾语，将格改为格。
例如：
All the people laughed at him. He at by all people. They make the bikes in China. The bikes by them in China. We visited that factory last summer. →主动语态
主语谓语宾语状语
That factory was visited by us last summer →被动语态
主语谓语宾语状语
四、如何正确使用被动语态
I often hear her sing this popular song.（主动语态）
She often this popular song.（被动语态）
1、在感；听，；让，，；看，，，；帮助；发现等动词后作宾语补足语的动词不定式都不带，但改成被动语态后都必须带。
宾补动词真奇怪，to在句中像妖怪。
主动句中to走开，被动句中to回来。
2、有些动词既是及物又是不及物，当它们和well, badly, easily等副词连用时，表示主语内在品质或性能，是不及物动词，用主动表示被动，这时不用被动语态，常见的有：write, read, clean, sell, wash, cook 等。
如：
(1)The cloth washes easily. 这布很好洗。
(2)This kind of phone sell well. 这种电话很畅销。
对比：
The books sell well. (主动句)
The books were sold out. (被动句)
The meat didn’t cook well. (主动句)
The meat was cooked for a long time. (被动句)
3、下列情况主动句不能改为被动句：
（1）感官系动词一般用主动形式表示被动意义，如：look, sound, smell, taste, feel ，seem 等。
这几个动词后接 。
如：
The new bike looks very beautiful. The food tastes delicious.
The pop music sounds beautiful.
4、有些“be +过去分词”的结构并不是被动语态，它们有可能是“系表结构（即系动词之后由过去分词来充当表语）。
”
⎩⎨⎧)()(.Fengping by closed is door The .closed is door The 被动语态。
这个门是由冯平来关的系表结构门是关着的。
⎩⎨⎧)()(.Mary by broken was glass The .broken is glass The 被动语态。
的这个玻璃杯是玛丽弄坏系表结构。
这个玻璃杯是坏的
主动语态与被动语态的转换口诀：
宾语提前主语变，原主变宾by 后见，时态人称be 关键。
