一、過去完成時的定義過去完成時既可表示過去某個時間或動作之前所發(fā)生的事情(常用時間狀語有already,before,ever,just,never,still,yet),也可表示過去某個時間或動作之前所發(fā)生的動作始終持續(xù)到過去某個時間(常接時間狀語:since+時間點,for+時間段)。如:*(2024·全國Ⅲ卷)Shehadsplitupwithherhusbandtheweekbefore.一周前她和丈夫分手了。*(2024·新高考全國Ⅰ卷)Neverhadheearnedsomuchmoneybeforeinhislife.他一生中從未賺過這么多錢。*WhenhewasinBeijing,hevisitedplaceswherehehadplayedasachild.他在北京的時候巡游了他兒時曾玩過的地方。*BythetimeJackreturnedhomefromEngland,hissonhadalreadygraduatedfromcollege.杰克從英國回到家時,他的兒子已經(jīng)高校畢業(yè)了。二、過去完成時的結(jié)構(gòu)過去完成時由“had+過去分詞”構(gòu)成。三、過去完成時的應(yīng)用1.與過去完成時連用的時間狀語可以多種多樣,運用它的主要依據(jù)是看其是否發(fā)生在“過去的過去”。如:*(2024·新高考全國Ⅰ卷)Afloodhadhittheareaearlierthatyearandthedamageitcausedhaddrivenawayanumberofbirds.那年早些時候,一場洪水攻擊了這個地區(qū),洪水造成的損失趕走了一些鳥類。*Iwassenttothevillagelastmonthtoseehowthedevelopmentplanhadbeencarriedoutinthepasttwoyears.上個月我被派到那個村子去看看過去兩年的發(fā)展安排是如何執(zhí)行的。*AfterDarwinhadspentsometimeinSouthAmerica,hisroomontheshipwascrowdedwithsamplesoftheplantsandanimalshehadcollected.達爾文在南美洲待了一段時間后,船上他的房間里擺滿了他收集的動植物標本。2.過去完成時還常常用于主句為過去時的賓語從句中。如:*(2024·江蘇高考)Hesaidthathehadheardthecallstopreservetheboxesandhadseenhowsomeofthemwerelistedashistoricbuildings.他說,他聽到了愛護這些箱子的呼聲,也看到其中一些被列為歷史建筑。*Darwinsuspectedthatthefincheshadevolvedfromacommonancestor,whichhadarrivedontheislandsalongtimebefore.達爾文懷疑,這些雀類是由一個共同的祖先進化而來的,他們很久以前就來到了這個島上。3.動詞expect,hope,suppose,think,want等的過去完成時可用來表示未實現(xiàn)的安排、準備或希望。如:*(2024·全國Ⅰ卷)Itdidn’tturnoutasIhadwished.結(jié)果并不如我所愿。*Wehadexpectedthatyouwouldbeabletowinthematch.我們原來預(yù)料你們能夠贏競賽。4.在hardly/scarcely...when...,nosooner...than...兩個結(jié)構(gòu)中的主句通常要用過去完成時。如:*Ihadhardlyopenedthedoorwhenhehitme.我剛打開門,他就打了我。*Hehadnosoonerboughtthecarthanhesoldit.他剛買了這輛車,轉(zhuǎn)瞬又賣了。5.Itwasthefirst/second...timethat...這是第一/其次……次……*Itwasthethirdtimethattheboyhadbeenlate.這是那個男孩第三次遲到了。語法填空。1.(2024·浙江高考)Byabout6000BC,peoplehaddiscovered(discover)thebestcropstogrowandanimalstoraise.
