专题九被动语态
【基础再现】
【重、难、考、点】
1. 被动语态的结构和表达的意义
2. 被动语态的一些特殊用法
3. 动词各种时态的被动语态的形式以及主动语态表示被动语态意义的结构【教学内容】
一、被动语态的用法
1. 不知道动作的执行者是谁。如:
This watch is made in China.
2. 没有必要指出动作的执行者是谁
More trees must be planted every year.
3. 需要强调或者突出动作的承受者时
Chinese is spoken by more and more people in the world.
4. 句子的主语不是人
Many buses were washed away by the flood.
二、 主动语态变为被动语态
We Visited that factory last summer →主动语态
last summer →被动语态
主语 谓语 宾语 状语
三、带双宾的谓语动词变为被动语态
有些动词带有两个宾语,即直接宾语和间接宾语,变被动语态时,可把其中一个宾语变成主语,另一个留在被动结构谓语后面。需要注意的是:若把直接宾语变成被动语态的主语,需要在间接宾语之间加上介词“to ”。
eg. He often tells us interesting stories . (主动语态)
⎭
⎬⎫.him by us to told often are stories g Interestin .him by stories g interestin told often are We (被动语态) 常带双宾语的词有:tell , show , lend , pass 等。
四、带复合宾语的动词变为被动语态
在主动语态中,某些动词之后带有复合宾语,即宾语和宾语补足语,这个复合宾语由动词不定式来充当,to被省略,但在被动语态中,这个to还要还原。
eg. I often hear her sing this popular song . (主动语态)
She is often heard to sing this popular song .(被动语态)
有这种用法的常用动词有:make ,let ,see ,hear ,watch ,feel ,notice等。五、动词短语变为被动语态
动词短语是一个不可分割的整体,在变化被动语态时,不可丢掉构成动词短语的介词或者副词。We should speak to old men politely. (主动语态)
Old men should be spoken to politely. (被动语态)
六、主动表被动
1. 当read,wash,clean,cook,cut,wear,carry等用作不及物动词且表示主语的某种属性时,通常要用主动形式表示被动意义:
The cloth washes well.
The book sells quickly.
This cheese doesn’t cut easily. It’s too soft.
This shirt will wear very long.
2.某些连系动词(如look,sound,smell,feel,taste,prove等)要用主动表被动,因为连系动词为不及物动词,它们没有被动语态形式:
That dog looks dangerous.
Your idea sounds a good one.
My advice proved to be wrong.
3. 在be worth doing 中doing表被动意义
This book is worth reading.
4. 在need , want , require 等少数表示“需要”的动词后的动名词用主动形式表被动意义: The plants want watering every day.
This wall requires repairing.
【注】以上结构中的动名词改用不定式则要用被动式表示被动意义:
This wall requires to be repaired.
七、不用被动语态的情况
1. 主动句的宾语是each other 或者反身代词时,不能用于被动语态。
The man introduced himself as Mr. White
They help each other study English.
2. 当主动句的谓语动词是表状态的及物动词时,不能用于被动语态
We will have a meeting.
3. 主动句的宾语是不定式或者动名词时, 不能用于被动语态中的主语
My brother enjoys watching TV .
He asked to have a try.
八、被动语态和系表结构的区别
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)。”
比较:(1)⎩⎨⎧)()(.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。 (2)⎩
⎨⎧)()(.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 【即时训练】
