ThePassiveVoice

（被动语态）小竞赛比一比英语中有几种语态你们知道吗？两种是哪两种？主动语态和被动语态英语动词有两种语态，主动语态和被动语态。主动语态表示主语是动作的执行者

例如：ManypeoplespeakEnglish.Heopenedthedoor.他打开了门.

被动语态表示主语是动作的承受者。

例如：Englishisspokenbymanypeople.

Thedoorwasopened.门被打开了。

语态分类何时用被动语态:

1.当我们不知道谁是动作的执行者;

2.或者没有必要指出谁是动作的执行者;

3.或者只需强调动作的承受者时，要用被动语态。被动语态结构■■■be+过去分词(PP)+(by…)

典型题例

将下列句子改为被动语态。

We

cleanourclassroomeveryday.

Ourclassroomiscleaned(byus)everyday.

在改写中应注意：1.把原来的宾语提到前面作被动语态的主语;2.把动词变成“be+过去分词”;3.主动语态中的主语变为介词by的宾语。1.They

make

shoesinthatfactory.

主语+及物动词+宾语Shoes

aremade(bythem)inthatfactory.变为被动语态一般现在时被动结构：

am/is/are+过去分词2.They

bought

tencomputerslastterm．Tencomputers

werebought(bythem)lastterm.一般过去时被动结构：

was/were+过去分词7.Mary

cantakegoodcareof

Tina

．Tina

canbetakengoodcareof

byMary.情态动词变被动：情态动词+be+过分被动语态的构成被动语态由“助动词be＋及物动词的过去分词”构成。助动词Be的变化是通过人称、数和时态的变化表现出来的。各种时态的被动语态的构成：1.一般现在时：2.一般过去时:4.带情态动词的被动语态：■■■am/is/are+pp

was(were)+pp情态动词+be+pp主动语态变被动语态口诀：宾语提前变主语，原主变宾by后见，时态人称be关键。一般现在时的被动语态：am/are/is+

一些特殊结构的被动结构:（1）感觉动词(hear,see等)改被动语态（2）使役动词(let,make等)改被动语态make,see,hear,watch等，后接不带“to”不定式时，变被动语态时要还原“to”

。如：

Isawhimleavethehouse.→Hewasseento

leavethehouse.思考2：IusuallyhearhersingEnglishsongsinthemorning.Sheisusuallyheard

Englishsongsinthemorning.tosing

Hemakesherhorseworkallday.Herhorseismade

allday.Myfatherletmegooutforapicnic.I

outforapicnic.toworkwaslettogo

口诀：这些动词真奇怪，主动句中to离开，被动句中to回来。（hear,let，have,make,see,watch…)9.Theforeignfriendsgaveussomewonderfulstamps.1)____________________somewonderfulstamps.2)Somewonderfulstamps_____________________________.
