被動語態(tài)講解-2

被動語態(tài)講解一．被動語態(tài)的運(yùn)用英語動詞有兩種語態(tài)，即主動語態(tài)（TheActiveVoice）和被動語態(tài)（ThePassiveVoice）。主動語態(tài)表示主語是動作的執(zhí)行者，被動語態(tài)表示主語是動作的承受著。例：Bellinventedthetelephonein1876.(主動語態(tài))ThetelephonewasinventedbyBellin1876.(被動語態(tài))ManypeoplespeakEnglish.(主動語態(tài))Englishisspokenbymanypeople.(被動語態(tài))下面幾種情況要用被動語態(tài)：（1）不知道誰是動作的執(zhí)行者。例如：Amanwaskilledinthehotelyesterday.（2）沒有必要指出誰是動作的執(zhí)行者。例如：Paperismadeofwood.（3）只需要強(qiáng)調(diào)動作的承受著。例如：Englishiswidelyusedallovertheworld.二．被動語態(tài)的構(gòu)成形式1．被動語態(tài)的基本時(shí)態(tài)變化被動語態(tài)通常為十種時(shí)態(tài)的被動形式,被動語態(tài)由be＋過去分詞構(gòu)成，be隨時(shí)態(tài)的變化而變化。以do為例，各種時(shí)態(tài)的被動語態(tài)形式為：1)am/is/are+done(過去分詞)一般現(xiàn)在時(shí)例Visitorsarerequestednottotouchtheexhibits.2）has/havebeendone現(xiàn)在完成時(shí)例Allthepreparationsforthetaskhavebeencompleted,andwe'rereadytostart.3）am/is/arebeingdone現(xiàn)在進(jìn)行時(shí)例Anewcinemaisbeingbuilthere．4）was/weredone一般過去時(shí)例IwasgiventenminutestodecidewhetherIshouldrejecttheoffer.5）hadbeendone過去完成時(shí)例Bytheendoflastyear,anothernewgymnasiumhadbeencompletedinBeijing.6）was/werebeingdone過去進(jìn)行時(shí)例AmeetingwasbeingheldwhenIwasthere.7）shall/willbedone一般將來時(shí)例Hundredsofjobswillbelostifthefactorycloses.8）should/wouldbedone過去將來時(shí)例Thenewswouldbesenttothesoldier'smotherassoonasitarrived.9）帶情態(tài)動詞的被動結(jié)構(gòu)。其形式為：情態(tài)動詞＋be＋過去分詞。例Thebabyshouldbetakengoodcareofbythebaby-sitter.2.被動語態(tài)的特殊結(jié)構(gòu)形式1)有些動詞可以有兩個(gè)賓語，在用于被動結(jié)構(gòu)時(shí)，可以把主動結(jié)構(gòu)中的一個(gè)賓語變?yōu)橹髡Z，另一賓語仍然保留在謂語后面。通常變?yōu)橹髡Z的是間接賓語。例Hismothergavehimapresentforhisbirthday.可改為Hewasgivenapresentbyhismotherforhisbirthday./Apresentwasgiventohimbyhismotherforhisbirthday.2)當(dāng)“動詞+賓語+賓語補(bǔ)足語”結(jié)構(gòu)變?yōu)楸粍诱Z態(tài)時(shí)，將賓語變?yōu)楸粍咏Y(jié)構(gòu)中的主語，其余不動。例Someonecaughttheboysmokingacigarette.可改為Theboywascaughtsmokingacigarette.3)在使役動詞have,make,get以及感官動詞see,watch,notice,hear,feel,observe等后面不定式作賓語補(bǔ)語時(shí)，在主動結(jié)構(gòu)中不定式to要省略，但變?yōu)楸粍咏Y(jié)構(gòu)時(shí)，要加to。例Someonesawastrangerwalkintothebuilding.可改為Astrangerwasseentowalkintothebuilding.4）有些相當(dāng)于及物動詞的動詞詞組，如“動詞＋介詞”，“動詞＋副詞”等，也可以用于被動結(jié)構(gòu)，但要把它們看作一個(gè)整體，不能分開。其中的介詞或副詞也不能省略。例ThemeetingistobeputofftillFriday.三、Itissaidthat+從句及其他類似句型一些表示“據(jù)說”或“相信”的動詞如believe,consider,expect,report,say,suppose,think等可以用于句型“It＋be＋過去分詞＋that從句”或“主語＋be＋過去分詞＋todosth.”。Itissaidthat…據(jù)說,Itisreportedthat…據(jù)報(bào)道，Itisbelievedthat…大家相信，Itishopedthat…大家希望，Itiswellknownthat…眾所周知，Itisthoughtthat…大家認(rèn)為，Itissuggestedthat…據(jù)建議。例Itissaidthattheboyhaspassedthenationalexam.（＝Theboyissaidtohavepassedthenationalexam.）四、謂語動詞的主動形式表示被動意義1.英語中有很多動詞如break，catch，clean，drive，lock，open，sell，read，write，wash等，當(dāng)它們被用作不及物動詞來描述主語特征時(shí)，常用其主動形式表達(dá)被動意義,主語通常是物。例Thiskindofclothwasheswell.2.表示“發(fā)生、進(jìn)行”的不及物動詞和短語，如：happen,last,takeplace,breakout,comeout,comeabout,cometrue,runout,giveout,turnout等以主動形式表示被動意義。例Howdothenewspaperscomeout?這些報(bào)紙是如何引出來的呢？3.系動詞沒有被動形式,但有些表示感受、感官的連系動詞feel,sound,taste,book,feel等在主系表結(jié)構(gòu)中常以主動形式表示被動意義。例Yourreasonsoundsreasonable五、非謂語動詞的主動形式表被動意義在某些句型中可用動名詞和不定式的主動形式表被動意義。1．在need，want，require,bear等詞的后面，動名詞用主動形式表示被動意義，其含義相當(dāng)于動詞不定式的被動形式。例Thehouseneedsrepairing（toberepaired）．這房子需要修理。2．形容詞worth后面跟動名詞的主動形式表示被動含義，但不能跟動詞不定式；而worthy后面跟動詞不定式的被動形式。例Thepicture-bookiswellworthreading．（＝Thepicture-bookisveryworthytoberead．）3.動詞不定式在名詞后面作定語，不定式和名詞之間有動賓關(guān)系時(shí)，又和句中另一名詞或代詞構(gòu)成主謂關(guān)系,不定式的主動形式表示被動含義。例Ihavealotofthingstodothisafternoon．(todo與things是動賓關(guān)系，與I是主謂關(guān)系。)六、如何將主動語態(tài)變成被動語態(tài)1．將主動語態(tài)變被動語態(tài)的基本方法為：①將主動語態(tài)的賓語作被動語態(tài)的主語；②謂語動詞變?yōu)椤癰e＋及物動詞的過去分詞”，并通過be的變化來表達(dá)出不同的時(shí)態(tài)；③主動語態(tài)的主語變?yōu)榻樵~by的賓語，組成介詞短語放在被動結(jié)構(gòu)中的謂語動詞之后。（有時(shí)by短語可以省略）。2．被動語態(tài)的一般疑問句是將一個(gè)助動詞置于主語之前；否定句是在第一個(gè)助動詞后加not；特殊疑問句的語序?yàn)椋阂蓡栐~＋一般疑問句。被動語態(tài)習(xí)題一、單項(xiàng)選擇。()1.Ifcitynoises____fromincreasing，people____shouttobeheardevenatdinner．A．a(chǎn)renotkept；willhavetoB．a(chǎn)renotkept；haveC．donotkeep；willhavetoD．donotkeep；haveto()2.---____thesportsmeetmightbeputoff．---Yes，italldependsontheweather．A．I'vebeentoldB．I'vetoldC．I'mtoldD．Itold()3.Greatchanges___inthecity,andalotoffactories___.A.havebeentakenplace;havebeensetupB.havetakenplace;havebeensetupC.havetakenplace;havesetupD.weretakenplace;weresetup()4.Thatsuit__over60dollars.A.hadcostedB.costedC.iscostedD.cost()5.---Doyoulikethematerial?---Yes,it___verysoft.A.isfeelingB.feltC.feelsD.isfelt()6.Itisdifficultforaforeigner____Chinese．A．writeB．towriteC．tobewrittenD．written()7.Ihavenomoreletters____，thankyou．A．totypeB．typingC．tobetypedD．typed()8.Nobodynoticedthethiefslipintothehousebecausethelightshappenedto___.A.beputupB.giveinC.beturnedonD.goout()9.Thecomputersonthetable___ProfessorSmith.A.belongsB.arebelongedtoC.belongstoD.belongto()10.---Whatdoyouthinkofthebook?---Oh,excellent.It’sworth___asecondtime.A.toreadB.tobereadC.readingD.beingread()11Diamond____inBrazilin1971.A.isfoundB.hasbeenfoundC.wasfoundD.hadbeenfound()12Chinese______bythelargestnumberofpeople．A．speakB．isspeaki
