③ 核心讲解
考点1:被动语态的基本概念与结构(★★★)
定义:当主语是动作的承受者时,谓语动词用被动语态。
语态
主语角色
示例
主动语态
动作执行者
Many people speak English.
被动语态
动作承受者
English is spoken by many people.
基本结构:
be + 过去分词(done)
be 动词要随人称、数和时态变化,过去分词永远不变。
考点2:各时态被动语态构成(★★★)
时态
主动语态
被动语态结构
示例
一般现在时
do/does
am/is/are + done
English is spoken in many countries.
一般过去时
did
was/were + done
The bridge was built in 2005.
一般将来时
will do
will be + done
The work will be finished tomorrow.
现在完成时
have/has done
have/has been + done
The room has been cleaned.
含情态动词
can/must/should do
can/must/should be + done
The rules must be obeyed.
现在进行时(了解)
am/is/are doing
am/is/are being + done
The road is being repaired.
过去进行时(了解)
was/were doing
was/were being + done
The house was being painted.
中考重点:前五种是被动语态的必考形式,后两种仅要求了解。
考点3:主动语态转被动语态"三步转换法"(★★★)
三步转换法:
第一步:找宾语 —— 将主动句中的宾语提前,变为被动句的主语。
第二步:变动词 —— 将谓语动词改为"be + 过去分词",be 的时态与原句一致。
第三步:移主语 —— 原主语变为"by + 宾格",置于句末(通常可省略)。
示例1:一般现在时
步骤
操作
结果
原句
—
Many people speak English.
第一步
宾语 English 提前
English ...
第二步
speak → is spoken(一般现在时,主语三单)
English is spoken ...
第三步
原主语 Many people → by many people
English is spoken by many people.
示例2:一般过去时
步骤
操作
结果
原句
—
Tom broke the window yesterday.
第一步
宾语 the window 提前
The window ...
第二步
broke → was broken(一般过去时,主语单数)
The window was broken ...
第三步
原主语 Tom → by Tom
The window was broken by Tom yesterday.
示例3:一般将来时
步骤
操作
结果
原句
—
They will build a new school next year.
第一步
宾语 a new school 提前
A new school ...
第二步
will build → will be built
A new school will be built ...
第三步
原主语 They → by them(通常省略)
A new school will be built next year.
示例4:含情态动词
步骤
操作
结果
原句
—
We must protect the environment.
第一步
宾语 the environment 提前
The environment ...
第二步
must protect → must be protected
The environment must be protected.
第三步
原主语 We → by us(通常省略)
The environment must be protected.
口诀:
宾提前,变主语;be + 过去分词来替换,时态不变要牢记;
原主语,by 后面变宾格,不需强调可省去。
考点4:主动语态变被动语态的特殊情况(★★)
① 双宾语结构
有些动词可带两个宾语:直接宾语(物)+ 间接宾语(人)。
结构
示例
give sb. sth.
He gave me a book.
send sb. sth.
She sent him a letter.
show sb. sth.
They showed us the way.
teach sb. sth.
Miss Li teaches us English.
tell sb. sth.
He told me a story.
两种被动转换方式:
转换方式
被动句
间接宾语(人)作主语
I was given a book (by him).
直接宾语(物)作主语
A book was given to me (by him).
注意:当直接宾语(物)作主语时,间接宾语前通常需加介词 to 或 for。
• give/send/show/teach/tell + to
• buy/make/cook + for
My mother bought me a gift. → A gift was bought for me.
② 感官动词和使役动词在被动语态中还原 to
主动语态
被动语态
see sb. do sth.
sb. is seen to do sth.
hear sb. do sth.
sb. is heard to do sth.
watch sb. do sth.
sb. is watched to do sth.
make sb. do sth.
sb. is made to do sth.
let sb. do sth.
sb. is let do sth.(let 例外,不加 to)
have sb. do sth.
(have 不用于被动语态)
示例:
• 主动:The boss made him work for 12 hours a day.
• 被动:He was made to work for 12 hours a day.
口诀:主动省 to,被动还 to;let 例外不加 to。
考点5:不能使用被动语态的情况(★★)
类别
例词
说明
不及物动词
happen, take place, appear, disappear, rise, fail
没有宾语,无被动
系动词
look, sound, smell, taste, feel, become, turn
表示状态,无被动
部分短语动词
belong to, take part in, consist of
表示归属/参与,无被动
典型错误示例:
❌ What was happened to you?
✅ What happened to you?
❌ The food is tasted delicious.
✅ The food tastes delicious.
考点6:主动形式表被动意义(★)
类型
示例
说明
感官/性质动词 + 副词
The book sells well.
书卖得好。
The pen writes smoothly.
这支笔写起来很顺滑。
The shirt washes easily.
这件衬衫容易洗。
need / require + doing
The flowers need watering.
花需要浇水了。
be worth + doing
The film is worth seeing.
这部电影值得一看。
注意:need doing = need to be done
The room needs cleaning. = The room needs to be cleaned.
栏目二:易错点拨
【易错1】被动语态中 be 动词的时态和人称变化
❌ 错误:The trees planted every spring.
✅ 正确:The trees are planted every spring.
【错因分析】被动语态必须有 be 动词,且 be 动词要随主语的人称、数和时态变化。
【避坑技巧】
时态
be 的变化
一般现在时
am / is / are + done
一般过去时
was / were + done
一般将来时
will be + done
现在完成时
have / has been + done
含情态动词
can / must / should be + done
【易错2】不及物动词没有被动语态
❌ 错误:The accident was happened last night.
✅ 正确:The accident happened last night.
【错因分析】happen 是不及物动词,没有宾语,不能构成被动语态。
【避坑技巧】
牢记常见不及物动词:happen, take place, appear, disappear, rise, fail, remain, exist
口诀:"发生出现和消失,上升失败都存在,不及物来无被动。"
【易错3】感官动词在被动语态中要还原 to
❌ 错误:The boy was seen enter the room.
✅ 正确:The boy was seen to enter the room.
【错因分析】主动语态中感官动词后的宾补不带 to,但变为被动语态后必须还原 to。
【避坑技巧】
主动
被动
see/hear/watch/notice sb. do sth.
sb. be seen/heard/watched/noticed to do sth.
make sb. do sth.
sb. be made to do sth.
let sb. do sth.
sb. be let do sth.(let 不加 to)
【易错4】双宾语结构中"物"作主语时介词不可丢
❌ 错误:A gift was bought me by my father.
✅ 正确:A gift was bought for me by my father.
【错因分析】当直接宾语(物)作被动句主语时,间接宾语(人)前需加介词 to 或 for。
【避坑技巧】
动词类型
介词
例词
give/send/show/teach/tell/lend/pass
to
give sth. to sb.
buy/make/cook/sing/find
for
buy sth. for sb.
【易错5】系动词没有被动语态
❌ 错误:The cake is tasted good.
✅ 正确:The cake tastes good.
【错因分析】taste 是系动词,表示"尝起来",不表示被动的动作。
【避坑技巧】
五大感官系动词——look, sound, smell, taste, feel——永远用主动形式表状态含义。判断标准:如果动词可以替换为 be 动词而句意基本不变,则是系动词,无被动。
【易错6】主动形式表被动意义
❌ 错误:This kind of book is sold well.
✅ 正确:This kind of book sells well.
【错因分析】sell 与 well, easily 等副词连用时,用主动形式表示被动意义。
【避坑技巧】
常见"主动表被动"的结构:
• sell well(卖得好)
• wash easily(容易洗)
• write smoothly(写起来顺滑)
• read easily(读起来容易)
