被动语态
当主语是动作的承受者时,谓语要用被动语态。
被动语态的构成
1.被动语态的构成形式是:助动词be+及物动词的过去分词。助动词be有人称、时态和
数的变化,其变化规则与be作为连系动词时完全一样。现以ask为例,将八种时态的
被动语态的肯定式、否定式和疑问式列表如下:
肯定式否定一疑问式
1amnotasked...
1amasked...Am1asked...?
He/Sheisnotasked...
一般现在时He/Sheisasked...Ishe/sheasked...?
We/You/Theyarenot
We/You/Theyareasked...Arewe/you/theyasked...?
asked...
I/He/Shewasnotasked...
I/He/Shewasasked...Wasl/he/sheasked...?
般过去时We/You/Theywerenot
We/You/Theywereasked...Werewe/you/theyasked...?
asked...
1ambeingasked...1amnotbeingasked...Am1beingasked...?
He/Sheisbeingasked...He/Sheisnotbeingasked...Ishe/shebeingasked...?
现在进行时
We/You/TheyarebeingWe/You/TheyarenotbeingArewe/you/theybeing

I/He/Shewasnotbeing
I/He/Shewasbeingasked...Wasl/he/shebeingasked...?

I/He/She/We/You/Theywill
I/He/She/Ws/You/TheywillWilll/he/she/we/you/they

一般将来时beasked...beasked...?
I/Weshall/wilnotbe
I/Weshall/willbeasked...Shall/Willl/webeasked...?

I/He/She/Ws/You/TheyI/He/She/We/You/TheyWouldl/he/she/we/you/they

过去将来时

过去完成时

2.含有情态动词的被动语态
含有情态动词的被动语态的构成形式:情态动词+be+及物动词的过去分词
>Teenagersshouldbeallowedtomaketheirowndecisions.
>Yourhomeworkmustbehandedintoday.
>Aconcertwillbeheldnextmonth.
>Maythetreesbeplantedbehindthehouse.
被动语态的用法
1.强调动作的承受者
>HisspokenEnglishhasbeenimprovedgreatly.
>Theyweregivenasecondchance.
>TheseletterswillbesenttoMissWhite.
2.当不知道或没必要说明谁是动作的发出者时
>Sometentshavebeenputupatthefootofthemountain.
>Anewschoolisbeingbuilthere.
>Airconditionersarewidelyusedinourdailylife.
3.当动作的发出者带有较长的修饰语时
>Thenovelwaswrittenbyayoungladywhowasdisabledbecauseofan
accident.
>Theadvicewasacceptedbythestudentswhohaddifficultyingettingalong
withothers.
>Ihavebeeninvitedtoahousewarmingpartybythenewneighborwho
camefromSouthAfrica.
主动语态转换为被动语态
1.主语+及物动词+宾语
❖Thegovernmenttakemanymeasurestopreventpollution.
—>Manymeasuresaretakentopreventpollution.
Myfatherfixedupthebike.
—>Thebikewasfixedupbymyfather.
2.主语+及物动词+宾语+宾语补足语
(1)主动句中的宾补变为被动句中的主补
❖Wesawhimout.
—>Hewasseenout.
❖Shehaskeptuswaitingforanhour.
—>Wehavebeenkeptwaitingforanhour.
(2)主动句中用带to的不定式作宾补,转换为被动句时要加上to(let除外)
❖Canyoumakethiswatchwork?
—>Canthiswatchbemadetowork?
❖Iheardtheboyplaythedrums.
—>Theboywasheardtoplaythedrums.
3.主语+及物动词+直接宾语+间接宾语
(1)这一句型转换成被动句时,直接宾语和间接宾语都可用作被动句的主语
*Theoldmangaveusmuchhelp.
—>Weweregivenmjchhelpbytheoldman.(间接宾语转化成主语)
—>Muchhelpwasgiventousbytheoldman.(直接宾语转化成主语)
,注意:当直接宾语转化为被动句的主语,间接宾语可以直接位于动词之后,也可以由介
词to或for引出。在间接宾语前加uton,这类动词有:give,offer,lend,pass,promise,
tell等;在间接宾语前加“for”,这类动词有:buy,cook,get,make<J
❖OurteachertaughtusEnglishsongs.
—>Englishsongsweretaughtusbyourteacher.(直接宾语转化成主语)
—>WeweretaughtEnglishsongsbyoutteacher.(间接宾语转化成主语)
(2)并非所有的间接宾语都可作为被动句的主语
❖ShewroteMissGreenaletter.
—>AletterwaswrittentoMissGreenbyher.(Y)
MissGreenwaswrittenaletterbyher.(x)
(3)宾语从句不能作为被动句的主语
❖Myfriendstoldmewhereweweregoingtomeet.
—>Iwastoldwhereweweregoingtomeetbymyfriends.W)
—>Wherewegoingtomeetwastoldmebymyfriends.(x)
主动形式表示被动含义
1.在主语是物的句子中,谓语动词是由某些及物动词转化来的比及物动词,如:sell,clean,
write,wash等。这些不及物动词的主动形式常表被动含义。
❖Thebooksellswell.
❖Theseclotheswasheasily.
❖Mypenwritessmoothly.
2.“need/require/want*动名词”结构表被动含义。
❖Yourhairneedscutting.
❖Theplantwantsv/ateringeveryday.
❖Thisproblemrequiresdiscussingindetail.
3."beworths动名词”结构表被动含义
❖Themovieisworthwatching.
*Thebookisworthreadingagain.
4.感官动词作如feel,smell,sound,taste,look等作为系动词时,常表示被动含义。
❖Silkfeelssoftandsmooth.
❖Theseapplessmelldelicious.
❖Yourideasoundsgreat.
❖Thecaketastesgood.
❖Itlooksnice.
5.某些表示“发生(happen,takeplace,occur)"、“爆发(breakout,burstout)"或"传播"
的不及物动诃。
❖Awarbrokeoutinthiscountrylastweek.
❖Anaccidenthappenedatthefirstcrossingonthisstreet.
❖ThemeetingwilltakeplaceonthemorningofFricay.
不能变为被动语态的主动句
1.反身代词作宾语时
❖Theyenjoyedthemselvesverymuch.
。Heisalwaystalkingtohimself.
2.当宾语时相互代词时
❖Weshouldhelpeachother,especiallyinthetimesofdifficulty.
❖Mygrandparentsunderstandoneanotherperfectly.
3.当宾语前有一个与主语相对应的所有格或物主代词时
❖Hedidn'tlendhisbiketome.
❖Shecriedhereyesout.
4.当宾语时行为者某一部分或官感时
❖Thelittlegirlwavedherhandstohermother.
❖Heshookhisheadtiredly.
5.某些表示所有关系或状态的及物动词不能变为被动语态,如:have,possess,cost,benefit,
suit等
