第九節(jié)被動語態(tài)第二部分語法精講精練第九節(jié)被動語態(tài)Listenattentively1.被動語態(tài)概述語態(tài)是動詞的一種形式,用以說明主語與謂語動詞之間的關系。英語的語態(tài)共有兩種：主動語態(tài)和被動語態(tài)。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者。被動語態(tài)是動詞的一種特殊形式,一般說來,只有需要動作對象的及物動詞才有被動語態(tài)。如：Heopenedthedoor.他打開了這扇門。(主動語態(tài))Thedoorwasopened.這扇門被打開了。(被動語態(tài))考點1有關被動語態(tài)的基礎知識第九節(jié)被動語態(tài)Listenattentively2.被動語態(tài)的構成被動語態(tài)由“助動詞be+及物動詞的過去分詞”構成。被動語態(tài)的時態(tài)變化只改變be動詞的形式,過去分詞部分不變。疑問式和否定式的變化也如此?？键c1有關被動語態(tài)的基礎知識第九節(jié)被動語態(tài)Listenattentively3.被動語態(tài)的用法在被動語態(tài)中,主語是動作的承受者,主要用于下列幾種情況：(1)不知道動作的執(zhí)行者是誰。如：ThiswatchismadeinChina.這塊手表是中國制造的。(2)沒有必要指出動作的執(zhí)行者是誰。如：Moretreesmustbeplantedeveryyear.每年都應該種更多的樹?？键c1有關被動語態(tài)的基礎知識第九節(jié)被動語態(tài)Listenattentively(3)強調(diào)或突出動作的承受者時。如：Chineseisspokenbymoreandmorepeopleintheworld.世界上越來越多的人說漢語。(強調(diào)漢語的使用廣泛)(4)句子的主語是動作的承受者。如：Manyhouseswerepulleddownbytheearthquake.許多房屋被地震摧毀了。考點1有關被動語態(tài)的基礎知識第九節(jié)被動語態(tài)Listenattentively1.一般現(xiàn)在時的被動語態(tài)(結(jié)構：主語+am/are/is+done)Russianisalsotaughtintheirschool.他們學校也教俄語。(肯定句)Thewindowsofourhousearecleanedonceaweek.我們房子的窗戶一星期擦一次。(肯定句)→Thewindowsofourhousearen’tcleanedonceaweek.(否定句,在is,am,are后加not)→Arethewindowsofourhousecleanedonceaweek?(一般疑問句,把is,am,are提句首)考點2初中階段主要掌握的幾種被動語態(tài)第九節(jié)被動語態(tài)Listenattentively2.一般過去時的被動語態(tài)(結(jié)構：主語+was/were+done)BeijingwasliberatedinJanuary,1949.北京是1949年1月解放的。(肯定句)ThesephotosweretakenontheGreatWall.這些照片是在長城拍攝的。(肯定句)→Thesephotosweren’ttakenontheGreatWall.(否定句,在was,were后加not)→WerethesephotostakenontheGreatWall?(一般疑問句,把was,were提句首)考點2初中階段主要掌握的幾種被動語態(tài)第九節(jié)被動語態(tài)Listenattentively3.一般將來時的被動語態(tài)(結(jié)構：will+be+done或is/am/aregoingto+be+done)Anewschoollibrarywillbebuiltnextyear.一個新的校圖書館將于明年建成。(肯定句)→Anewschoollibrarywon’tbebuiltnextyear.(否定句,在will后加not)→Willanewschoollibrarybebuiltnextyear?(一般疑問句,把will提句首)考點2初中階段主要掌握的幾種被動語態(tài)第九節(jié)被動語態(tài)ListenattentivelyAnewschoollibraryisgoingtobebuiltnextyear.一個新的校圖書館將于明年建成。(肯定句)→Anewschoollibraryisn’tgoingtobebuiltnextyear.(否定句,在is/am/are后加not)→Isanewschoollibrarygoingtobebuiltnextyear?(一般疑問句,把is/am/are提句首)考點2初中階段主要掌握的幾種被動語態(tài)第九節(jié)被動語態(tài)Listenattentively4.帶情態(tài)動詞的被動語態(tài)(結(jié)構：情態(tài)動詞+be+done)(1)肯定句式：主語+情態(tài)動詞+be動詞原形+過去分詞Thecomputermustberepairedrightnow.電腦必須立刻修。Tablescouldbemadeofstoneatthattime.那時桌子可由石頭做成?？键c2初中階段主要掌握的幾種被動語態(tài)第九節(jié)被動語態(tài)Listenattentively(2)否定句式：主語+情態(tài)動詞+not+be動詞原形+過去分詞ItcannotbedonebyPeter.這件事不可能是彼得干的。Wastepapershouldnotbethrownontheroad.廢紙不應該扔在路上。(3)一般疑問句式：情態(tài)動詞+主語+be動詞原形+過去分詞Mustthetreesbewaterednow?這些樹必須現(xiàn)在澆水嗎？考點2初中階段主要掌握的幾種被動語態(tài)第九節(jié)被動語態(tài)Listenattentively(4)特殊疑問句式：特殊疑問詞(不作主語)+情態(tài)動詞+主語+be動詞原形+過去分詞特殊疑問詞(作主語)+情態(tài)動詞+be動詞原形+過去分詞Whencanmycomputerberepaired?我的電腦什么時候能修好？Whatmustbedonenext?下一步該做什么？考點2初中階段主要掌握的幾種被動語態(tài)第九節(jié)被動語態(tài)ListenattentivelyForthethirdstraightyear，theWorldRiceConference__1__Cambodianriceastheworld’sbest.ThisyearCambodiasharestheawardwithThailand.Cambodia__2__justonepercentoftheworld’sricein2012.Itistryingtoincreasethatamount.Theawardmayhelp.語法選擇
