初中英语语法归纳复习:被动语态
重难点:掌握八种常见时态的被动语态,并能根据不同情景,灵活运用被动语态。【知识总结归纳】
一. 概念:表示动作与主语之间是被动关系的句子是被动语态。
二. 主动语态与被动语态之间如何转换
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
三. 各种不同时态的主动语态与被动语态的对比
四. 如何正确使用被动语态
1. 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。
2. 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)
443
4421复合宾语
宾语补足语宾语
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。
3. 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 4. 只有及物动词和可有宾语的动词+介词词组才可以有被动语态。
eg. ⎩
⎨⎧)()(.China in place taken been have changes Great .China in place taken have changes Great 错误正确 ⎩⎨⎧)
()(.sea deep the in d disappeare was dolphin The .sea deep the in d disappeare dolphin The 错误正确 【总结】
一、被动语态的构成形式
1. 被动语态的基本时态变化
被动语态通常为十种时态的被动形式, 被动语态由be +过去分词构成,be 随时态的变化而变化。以do 为例,各种时态的被动语态形式为:
1) am/is/are +done (过去分词) 一般现在时
例Visitors are requested not to touch the exhibits.
2) has /have been done 现在完成时
例All the preparations for the task have been completed, and we're ready to start.
3) am/is /are being done 现在进行时
例A new cinema is being built here .
4) was/were done 一般过去时
例I was given ten minutes to decide whether I should reject the offer.
5) had been done 过去完成时
例 By the end of last year, another new gymnasium had been completed in Beijing.
6) was/were being done 过去进行时
例A meeting was being held when I was there.
7) shall/will be done 一般将来时
例Hundreds of jobs will be lost if the factory closes.
8) should/would be done 过去将来时
例The news would be sent to the soldier's mother as soon as it arrived.
9) shall/will have been done 将来完成时(少用)
例The project will have been completed before July.
2. 被动语态的特殊结构形式
1)带情态动词的被动结构。其形式为:情态动词+be +过去分词。
例The baby should be taken good care of by the baby-sitter.
2) 有些动词可以有两个宾语,在用于被动结构时,可以把主动结构中的一个宾语变为主语,另一宾语仍然保
留在谓语后面。通常变为主语的是间接宾语。
