被动语态专题课件

被动语态专题课件篇一：初中被动语态课件教学过程一、复习预习被动语态是动词的一种特殊形式，表示句子中的主语是动作的承受者，汉语往往用“被”、“受”、“给”等词来表示被动意义。

今天我们复习被动语态，知识点小而多，希望在学习中认真再认真。

二、知识讲解知识点1. 被动语态的用法在被动语态中，主语是动作的承受者，主要用于下列几种情况： 1、不知道动作的执行者是谁。

如： This watch is made in China. 这块手表是中国制造的。

some new computers were stolen last night. 一些新电脑在昨晚被盗了。

2、没有必要指出动作的执行者是谁。

如： More trees must be planted every day. 每年都应该种更多的树。

Eight hours per day for sleep must be guaranteed. 每天8小时睡眠必须得到保证。

3、需要强调或突出动作的承受者时。

如：Chinese is spoken by more and more people in the world. 世界上越来越多的人说汉语。

4、句子的主语不是人。

如：Many houses were washed away by the flood. 许多房屋被洪水冲走了。

知识点2. 被动语态的结构（1）被动语态的基本结构为：be + 动词的过去分词【记忆窍门】宾变主，主变宾，by短语后面跟。

谓语动词变被动，be后―过分‖来使用。

(2) 被动语态结构与SVC(动词－ed形式作表语)结构的区别被动语态表示动作，句子主语为动作的对象，SVC结构表示主语的特点或所处的状态，其中的过去分词相当于形容词，be只有一般时态和完成时态。

被动结构的时态一般要与相应的主动结构一致。

下面把这两种结构作一比较：1、The library is usually closed at 6.图书馆通常六点关门。

(被动语态) The library is now closed.图书馆关门了。

(SVC结构)2、The bridge was completed in 1968.桥是1968年建成的。

(被动语态) The bridge is completed.桥已修好。

(SVC结构)3、The glass was broken by my sister.玻璃杯是我妹妹打破的。

(被动语态) The glass is broken.玻璃杯破了。

(SVC结构) 为了便于考生们的理解，再举几个SVC结构的例句：The gun is loaded.枪装上子弹了。

Your composition is well written.你的作文写得很好。

The door is locked.门锁着。

He was injured in the leg.他腿部受了伤。

知识点3. 主动语态变为被动语态1、要将主动句中的宾语变为被动句中的主语，若主动句中的宾语是人称代词，要将宾格变为主格。

2、把主动句中的主语变为被动句中的宾语，主格代词变成宾格代词，并由by 引导。

3、谓语动词变成相应的被动形式。

主动语态：动作执行者 + 谓语动词主动形式 + 动作承受者被动语态：动作承受者 + 谓语动词被动形式 + 动作执行者他被我们要求唱一首英文歌。

知识点4. 时态与语态的结合(1) 带双宾语的谓语动词变为被动语态谓语动词带双宾语时，既可以将间接宾语转化成主语，也可以将直接宾语转化成主语。

若将间接宾语转化成主语，则保留直接宾语；若将直接宾语转化成主语则保留间接宾语，且在被保留的间接宾语前加上介词to或for。

如：A book was given to me by her.(2) 动词短语变为被动语态许多由不及物动词和介词、副词构成的动词短语相当于及物动词，可以有宾语，也可以有被动语态。

但是动词短语是一个不可分割的整体，在变为被动语态的时候，不可丢掉构成动词短语的介词或者副词。

如：We should speak to old men politely. (变为被动语态）Old men should be spoken to politely.（to 不可省略） His best friend often looks after him.He is often looked after by his best friend.(3)带复合宾语的动词变为被动语态宾语加上宾语补足语一起构成复合宾语。

变被动语态时，只把宾语变为被动句的主语，宾语补足语保留在原处，成为主语补足语。

如：(4)变为被动语态后动词形式的选择主动句中在感官动词see, hear, watch, feel, notice等，及使役动词let, make, have等后跟省略to的不定式，变为被动句时，应加上不定式符号to。

如：He makes the girl stay at home. The girl is made to stay at home by him. (5)日积月累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. ）易错点1及物动词(或动词短语)有被动语态；不及物动词(或动词短语)无被动语态。

例如：（1）【误】The accident was happened this morning.【正】The accident happened this morning.（2）【误】 Great changes were taken place in the past ten years in China. 【正】 Greatchangeshave taken place in the past ten years in China.易错点2主动句中带双宾语的动词，若将直接宾语改为被动句的主语，动词后应加to 或for；如将间接宾语改为被动句的主语,不需加介词。

例如：【误】A present was given everybody yesterday. 【正】 Apresentwasgivento everybody yesterday. 【正】Everybody was given a present yesterday.常见的带双宾语的动词有：give, send, pass, show, bring, tell( 以上单词通常用 to) ,buy, get, read, make (以上单词通常用for)。

易错点3―感使动词‖(feel, hear, listen to, let, have, make, see, watch, notice, look at)真奇怪，主动结构―to‖走开，被动结构又请来，十个动词要记牢，不会被它再难倒。

例如：（1）【误】Lily is often heard sing in her bedroom.【正】Lilyisoften heard to sing in her bedroom.（2）【误】When father was young, he was made work from morning till night. 【正】When father was young, he was made to work from morning till night.篇二：被动语态专题被动语态专题申青青一英语动词有两种语态：即主动语态和被动语态。

二被动语态的构成：被动语态由“be+及物动词的过去分词”构成。

be有人称、数和时态的变化。

被动语态句型的基本结构:主语（承受者）+ be + v. pp + by 执行者三主、被动语态的转换主动语态：主语＋及物动词＋宾语（＋其他）被动语态：主语＋be＋及物动词过去分词＋by＋宾语（＋其他）His brother washes bowls every dayBowls are washed bt his brother every day四各种时态的被动语态结构1）am/is/are +done (过去分词) 一般现在时2) has /have been done 现在完成时3) am/is /are being done 现在进行时4 )was/were done 一般过去时5) had been done 过去完成时6)was/were being done 过去进行时7)shall/will be done 一般将来时8)should/would be done 过去将来时五被动时态中的特殊形式1）带情态动词的被动结构其形式为：情态动词＋be＋过去分词。

2）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.”。

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。

It is said that the boy has passed the national exam＝The boy is said to have passed the national exam六主动语态变被动语态应注意的问题1.把主动语态变为被动语态时，应保留主动语态原来的时态。

如：She often cleans the house.The house is often cleaned by her.2.有些动词可以有双宾语，在用于被动结构时，通常变为主语的是间接宾语（sb.）His mother gave him a present for his birthdayHe was given a present by his mother for his birthday.3 在使役动词have, make, get以及感官动词see, watch, notice, hear, feel等后接动词原形的变为被动结构时，要加toSomeone saw a stranger walk into the building =A stranger was seen to walk into the building. 七用主动形式表示被动含义的情况有1、系动词 taste, smell, feel, sound, prove等可用主动形式表达被动意义。
