文檔簡介
17/17動詞(一)動詞的時態(tài)基本概念在初中英語中,共有八個時態(tài)需要掌握。它們是:theSimplePresent(一般現(xiàn)在時)theSimplePast(一般過去時)theSimpleFuture(一般將來時)thePresentContinuousTense(現(xiàn)在進行時)thePastContinuousTense(過去進行時)thePresentPerfectTense(現(xiàn)在完成時)thePastPerfectTense(過去完成時)thePastFutureTense(過去將來時)實例與用法介紹1.theSimplePresent(一般現(xiàn)在時)一般現(xiàn)在時表示目前的狀態(tài)以及經(jīng)常習(xí)慣發(fā)生的動作。例如:Theearthturnsroundthesun.(宇宙不變的真理)Igetupatsixeverymorning.(經(jīng)常習(xí)慣發(fā)生的動作)WeareJuniorThreestudents.(表示目前的狀態(tài))2.theSimplePast(一般過去時)一般過去時可以表示過去發(fā)生的動作或情況,在句子中往往有明確的表示過去的時間狀語。例如:1)Noneofthefootballgameshadbeenmoreexcitingthantheonehewatchedyesterday.(句子中有yesterday這個明確表示過去的時間狀語)2)lastnightIgavealectureinthemeetinghall.(lastnight表示過去的時間,所以我們也用一般過去時)一般過去時有時還可以表示過去習(xí)慣的動作。例如:Whenhewasinthecountry,helikedtotakeawalkaftersupper.(句中l(wèi)iked表示他過去在農(nóng)村市常常發(fā)生的動作)Iusedtogotoworkbybus.(usedto表示“過去常?!保?.theSimpleFuture(一般將來時)一般將來時即表示將來某個時間要發(fā)生的動作或存在的狀態(tài),也表示將來經(jīng)常發(fā)生的動作。例如:Wearegoingtoenterseniorhighschoolinthenearfuture.(inthenearfuture是一個表示將來的時間狀語,所以用一般將來時,表示將來某個時間要發(fā)生的動作)TherewillbemoreandmoreforeignersinChina.(本句表示將來經(jīng)常發(fā)生的動作,意為:在中國會有越來越多的外國人)4.thePresentContinuousTense(現(xiàn)在進行時)現(xiàn)在進行時表示目前正在進行的動作,句子中往往有now,atpresent,thesedays等做時間狀語。例如:1)Wearelearningeighttensesnow.(我們用一般現(xiàn)在進行時,表示目前正在進行的動作)2)Listen!Theyaresingingintheclassroom.(句子中l(wèi)isten表示“聽”,說明句中的動作正在進行之中,因此我們用現(xiàn)在進行市)5.thePastContinuousTense(過去進行時)過去進行時表示過去一個時間點或時間段中正在發(fā)生的動作。例如:1)Wewerehavingsupperatsixyesterdayevening.(過去某一個時間點atsixyesterdayevening正在發(fā)生的動作)2)Theywereplayingvideogamesfrom2p.m.to4p.m.yesterdayafternoon.(過去某一個時間段from2p.m.to4p.m.yesterdayafternoon正在發(fā)生的動作)3)WewerehavinganEnglishlessonwhenTomcamein.(當(dāng)過去某一個動作werehaving正在進行時,另一個動作came發(fā)生了)6.thePresentPerfectTense(現(xiàn)在完成時)現(xiàn)在完成時表示過去發(fā)生的動作對現(xiàn)在造成的影響與結(jié)果,或表示過去開始并持續(xù)到現(xiàn)在的動作或狀態(tài)。例如:1)Wehavelearnedabouteighttensessofar.(sofar表示“至今為止”,常用于現(xiàn)在完成時)2)WehavestudiedEnglishforsixyears.(這里的for+時間段表示從過去開始并持續(xù)到現(xiàn)在的動作,用現(xiàn)在完成時)3)Ihavenevermethimsincelastmonth.(這里的since+時間點表示過去發(fā)生的動作對現(xiàn)在造成的影響與結(jié)果,所以用現(xiàn)在完成時)7.thePastPerfectTense(過去完成時)過去完成時表示在過去某一個時間或動作前已經(jīng)發(fā)生或者完成的動作,而且它常常用在賓語從句中。例如:1)Bytheendoflastmonth,theyhadlearned2000Englishwords.(bytheendoflastmonth表示“到上一個周末為止,所以用過去完成時)2)Aftertheboyhadfinishedthehomework,hewatchedTV.(finish這個動作發(fā)生在過去某一動作watched之前,所以用過去完成時)8.thePastFutureTense(過去將來時)過去將來時表示對于過去某一個時間而言將要發(fā)生的動作或存在的狀態(tài),它常用在賓語從句中。例如:1)Hesaidwewouldwinthegamethenextweek.(這句句子里用過去將來時是因為said和thenextweek的關(guān)系)練習(xí):Ⅰ.Fillintheblankswiththeverbsintheirproperforms:I_________(finish)myhomeworkwhileyou__________(sleep)thisafternoon.Shesaidshe__________(nodo)itagain.I__________(meet)himlastweekbutI___________(notsee)himsincethen.Johnalways_______(say)thathestill___________(notknow)howtousethePresentPerfectTense.IfPeter__________(e)tomorrow,I___________(tell)himaboutit.Herelderbrother__________(join)thearmytwoyearsago.They___________(learn)severalFrenchsongsbytheendoflastterm.Look!We___________(catch)suchabigfish.Theteachersaidtheearth__________(turn)aroundthesun.Whenyou___________(have)ameeting,I________(buy)somecakesinthenextshop.She__________never_________(be)totheGreatWallbefore.We__________(talk)aboutthedevelopmentoftheInternetonthelecturenextMonday.They___________(learn)thehistoryofChinathesedays.They____________(make)modelshipsfrom3:00to5:00yesterday.You__________(fail)intheexamifyou____________(notwork)hard.Ⅱ.Choosethebestanswers:()1.Ifit_______tomorrow,we_______onatriptoHangzhou.A.rains…won’tgo
