初中英语语法归纳：被动语态知识讲解

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） 4434421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。

例His mother gave him a present for his birthday. 可改为 He was given a present by his mother for his birthday.3) 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。

例Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.4）在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。

例Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building.5) 有些相当于及物动词的动词词组，如“动词＋介词”，“动词＋副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。

其中的介词或副词也不能省略。

例The meeting is to be put off till Friday.3. 非谓语动词的被动语态v.+ing 形式及不定式 to do 也有被动语态(一般时态和完成时态) 。

例I don't like being laughed at in the public.二、如何使用被动语态学习被动语态时，不仅要知道被动语态的各种语法结构，还要知道在哪些情况中使用被动语态。

1. 讲话者不知道动作的执行者或不必说出动作的执行者 (这时可省 by 短语)。

例 My bike was stolen last night.2. 借助被动的动作突出动作的执行者。

例 I was given ten minutes to decide whether I should accept the offer.3. 为了更好地安排句子。

例The well-known person got on the bus and was immediately recognized by people. （一个主语就够了）三、 It is said that+从句及其他类似句型一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It＋be＋过去分词＋that从句”或“主语＋be＋过去分词＋to do sth.”。

有：It is said that…据说,It is reported that…据报道，It is believed that…大家相信，It is hoped that…大家希望，It is well known that…众所周知，It is thought that…大家认为，It is suggested that…据建议。

例It is said that the boy has passed the national exam. （＝The boy is said to have passed the national exam. ）四、谓语动词的主动形式表示被动意义1.英语中有很多动词如 break，catch，clean，drive，lock，open，sell，read，write，wash等，当它们被用作不及物动词来描述主语特征时，常用其主动形式表达被动意义,主语通常是物。

例 This kind of cloth washes well.注意：主动语态表被动强调的是主语的特征，而被动语态则强调外界作用造成的影响。

试比较：The door won't lock．（指门本身有毛病）The door won't be locked．（指不会有人来锁门, 指“门没有锁”是人的原因）2. 表示“发生、进行”的不及物动词和短语，如：happen, last, take place, break out, come out,come about, come true, run out, give out, turn out等以主动形式表示被动意义。

例 How do the newspapers come out? 这些报纸是如何引出来的呢？3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。

例Your reason sounds reasonable五、非谓语动词的主动形式表被动意义在某些句型中可用动名词和不定式的主动形式表被动意义。

1．在need，want，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。
