被动语态 (4)

1、被动语态被动语态一、语态概述：英语的语态是通过动词形式的变化表现出来的。英语中有两种语态:主动语态和被动语态。1.主动语态表示主语是动作的执行者。 例如:many people speak chinese.说明：1、谓语:speak的动作是由主语many people来执行的。2.被动语态表示主语是动作的承受者,即行为动作的对象。例如:chinese is spoken by many people.说明：主语english是动词speak的承受者。二、被动语态的构成：由"助动词be+及物动词的过去分词"构成。注意：人称、数和时态的变化是通过be的变化表现出来的；数量随新的

2、主语变，时态和原句保持一样。现以speak为例说明被动语态在各种时态中的构成。一般现在时            am/is/are+spoken       现在进行时            am/is/are being+spoken一般过去时      &

3、#160;     was/were+spoken       过去进行时            was/were being+spoken现在完成时            have/has been+spoken     

4、60; 过去完成时            had been+spoken一般将来时            will/shall be+spoken       过去将来时            would be+spok

5、en含有情态动词          情态动词+be+过去分词三、被动语态的用法：(1)不知道或没有必要说明动作的执行者是谁。例如:some new computers were stolen last night. 一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)      this bridge was founded in 1981.这座桥竣工于1981年。(2)强调动作的承受者,而不强调动作的执行者。例如:the glass was broken by

6、 mike.玻璃杯是迈克打破的。      this book was written by him.这本书是他写的。      your homework must be finished on time.你们的家庭作业必须及时完成。(3)还有下列常用句型（that后面跟句子）：it is said that.  据说     it is reported that.  据报道it is hoped that.  希望

7、60; it is believed that.  人们相信it is announced that.  据宣布      it is (well) known that.  众所周知it has been decided that.  已经决定    it is supposed that.  人们认为it is suggested that.  有人建议    it must be remembered that.

8、0; 务必记住例：it is reported that the weather will be cold tomorrow.四、主动语态变被动语态的方法：(1)把主动语态的宾语变为被动语态的主语。(2)把谓语变成被动结构“be+过去分词”。(3)be动词要和新的主语(即原来的宾语)在人称和数量上保持一致，时态和原句一样不变。(4)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。例如:(一)“主+谓+宾”结构。例如：i was doing my honework. my homework was being done by me.(二)“主+谓+宾+宾补”结构。例如：he made

9、me clean the room. i was made to clean the room.注意：当主动语态中的谓语动词后接省略to的不定式时，变被动语态时要还原to.这类动词有：一感feel   二听listen to；hear   三让let；make；have   四看watch；see；look；notice   半帮助help (to) do(三)“主+谓+直宾+间宾”结构。例如：he gave me a pen. i was given a pen by him./ a pen was given

10、to me .五、特殊情况(一)主动语态表被动的情况：1.open.lock.write.read.sell.clean.wash.cut.burn.drive等动词做不及物动词时，它们的助于为物，可用主动语态表示被动含义。例如：the kind of coat sells well.2.感官动词可以表示被动含义。   例如：the news sounds good.3.want/require/need+doing相当于want/require/need to be done。例如：my bike needs repairing.= my bike needs to be

11、 repaired.(二)不能变被动语态的情况：1.不及物动词不能用于被动语态，因为它们没有宾语。2.主动句的宾语是反身代词或each other时。例如：she praised herself. 她自我表扬。3.主动句的谓语是表状态的动词时，如 break out, belong to, cost, deserve, fit, have ( 有、使)，hold (盛下、装下)，lack, resemble, suit, take part in, take place, want, wish等动词不能变为被动语态。例如：we have a meeting.4.主动句的宾语是doing或to

12、do 时。例如：climbing trees is dangerous.(三)其它几点说明：1. 除助动词be外，动词get有时也可跟过去分词构成被动语态，是比较口语化的一种被动语态。这种结构中很少用by短语。例如：i got lost in the huge market. 在那个巨大的市场中我迷失了方向。you might get killed/hurt.  你会送命/受伤的。2. “have/get+宾语+过去分词” 这个句型也表达了一种被动的意思。例如：ill have the bike repaired in no time. 我一会就把自行车修好。i had my wal

13、let stolen last sunday when i was shopping. 上星期天买东西的时候我的钱夹被盗。he got his leg broken when playing football.  踢足球的时候他把腿弄断了。六、练习1、将下列句子变成被动语态：主要步骤是：把原句的宾语变成主语（代词宾格要变成主格）；把原句的谓语动词变成被动形式（注意：时态不变，新谓语动词与新主语要一致，疑问句要注意助动词的转换）。复合句中如有可能主句和从句都要变成被动语态。1）he gave me a present.      i w
