3一、現(xiàn)在完成時(shí)態(tài)（have∕hasdone）

用法：1）動(dòng)作發(fā)生在過去，一直延續(xù)到現(xiàn)在，對(duì)目前有影響。（延續(xù)性動(dòng)詞的“已完成”或“未完成”用法）

2)動(dòng)作發(fā)生在過去,點(diǎn)已經(jīng)完成，并與現(xiàn)在的情況有聯(lián)系。（瞬間性動(dòng)詞的“已完成”用法）說明：“已完成”用法表示動(dòng)作已結(jié)束，而“未完成”用法則表示動(dòng)作有可能繼續(xù)延續(xù)下去。41）我曾經(jīng)在某個(gè)地方見過她。2）到目前為止,該橋?qū)纯⒐ぁ?）她剛剛買了一部新自行車。4）我們已經(jīng)在這里生活了十年。5）我學(xué)習(xí)英語的時(shí)間長(zhǎng)達(dá)25年了。6）自1997年以來，我就沒見過她了。Ihaveeverseenhersomewhere.→2

Shehasjustboughtanewbike.→2Wehave

alreadylivedherefortenyears.→1

I'vestudiedEnglishfortwenty-fiveyears.→1

Ihaven'tseenhersincetheyearof1997.→251、現(xiàn)在完成時(shí)態(tài)用法（一）：延續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)

開始于過去的動(dòng)作一直持續(xù)到現(xiàn)在。謂語動(dòng)詞一般為延續(xù)性動(dòng)詞。①Anoldwomanwalkedoutintothemiddleofthestreet.Thepolicemanyelledtoher,“Don’tyouknowwhatitmeanswhenIholdupmyhand?”Theladysaid,“SureIdo.Ihavebeenaschoolteacherfor28yearsnow.”②Ihavelivedherefor3years.③TheteacherhastaughtinthisschoolsinceIcamehere.④I’veworkedinthiscompanysinceIleftschool.⑤Sincetimebegan,manhaslivedinfearoffire.6或者，由上下文明確告知，開始于過去的動(dòng)作只持續(xù)到說話時(shí)刻為止即已結(jié)束。例如：

①A：Haveyouwaitedlong?

B：I’vewaitedforthreehours.

②I’vewaitedforhimallday;Idon’twanttowaitanylonger.

這種現(xiàn)在完成時(shí)的特點(diǎn)：

1）謂語動(dòng)詞一般為延續(xù)性動(dòng)詞。

2）動(dòng)作發(fā)生的時(shí)間是過去，但這一動(dòng)作持續(xù)到現(xiàn)在。

3）與這種用法的現(xiàn)在完成時(shí)態(tài)連用的時(shí)間狀語通常是表示“一段時(shí)間”的時(shí)間狀語，以說明某個(gè)動(dòng)作或狀態(tài)持續(xù)了多久。

7※與此種用法的現(xiàn)在完成時(shí)態(tài)搭配的時(shí)間狀語：

⑴since＋時(shí)間點(diǎn)

①I’veworkedinthiscompanysince1980.

②I’veworkedinthiscompanysinceIleftschool.

注意不能說：sincethreeyears，而要說sincethreeyearsago。

⑵for＋時(shí)間段

①I’veworkedinthiscompanyforthreeyears.

②GreatchangeshavetakenplaceinBeijingforthepastfewyears.8since的四種用法

1)since+過去一個(gè)時(shí)間點(diǎn)(如具體的年、月、日期、鐘點(diǎn)、1980,lastmonth,halfpastsix)。

Ihavebeenheresince1989.

2)since+一段時(shí)間+ago

Ihavebeenheresincefivemonthsago.

3)since+從句

Greatchangeshavetakenplacesinceyouleft.

Considerabletimehaselapsedsincewehavebeenhere.

4)Itis+一段時(shí)間+since從句

ItistwoyearssinceIbecameapostgraduatestudent.9⑶“到目前為止……”：untilnow,upuntilnow,uptonow,uptillnow,sofar等。例如：

Wehaveupuntilnowfailedtotakeanyactiontodecideonacommonlanguagethatwouldfurthercommunicationbetweennations.

⑷

“在最近幾世紀(jì)／年／月以來……”：inthepastfewyears,overthepastfewyears,duringthelastthreemonths,forthelastfewcenturies,throughcenturies,throughouthistory等。例如：

①Throughouthistorymanhashadtoacceptthefactthatalllivingthingsmustdie,fortheverynatureoflifeincludesdeath.

②Throughcenturiesthebizarreanticsofsleepwalkershavepuzzledpolice,perplexedscientistsandfascinatedwriters.102、現(xiàn)在完成時(shí)態(tài)用法（二）：過去發(fā)生但與現(xiàn)在仍有聯(lián)系的動(dòng)作或狀態(tài)

表示在不確定的過去發(fā)生的某一動(dòng)作與現(xiàn)在的情況有聯(lián)系。謂語動(dòng)詞一般為短暫性動(dòng)詞。

①Hehasbrokenhisleg.②Hebrokehisleg.

③Amoderngirlwenttothetheatrewithavestandapairofslippers.Theticket-examinerturnedherawayverypolitely:“Miss,NOADMISSIONWITHSLIPPERS.”“Really?”thegirltookofftheslippersandcarriedtheminherhands,“ThenIwillgoinbarefootedly.”“Oh,mygod!”theticket-examinercriedout,“Fortunately,IhavenottoldherNOADMISSIONWITHAVEST.”

④A：WhathashappenedtoJane?Sheiscrying.

B：Shebrokethedining-roomwindow.Shehastofacethemusicwhenherfathergetshome.11⑤Mr.Oddsworksinabankandlivesonhisown.Theonlyfamilyhehasisinthenexttown:hissisterlivestherewithherhusband,andherson,Mark.LastweekMr.Oddshadasurprise.Hedrovehomefromthebankattheusualtime,drivingneithertooslowlynortoofast;heparkedhiscarwherehealwaysparkedit,outofthewayofothercars,andhewentinsidetomakehiseveningmeal.Straightaway,therewasaknockatthedoor.Mr.Oddsopenedthedoor,tofindapolicemanstandingonthedoorstep.

“WhathaveIdonewrong?”Mr.Oddsaskedhimself.“HaveIdrivenonthewrongsideoftheroad?Hastherebeensometroubleatthebank?HaveIforgottentopayanimportantbill?”

“Hello,Uncle,”saidthepoliceman,“Myname’sMark.”

⑥Youshouldhaveputthemilkintoicebox;Iexpectit

undrinkablebynow.

A．becameB．hadbecomeC．hasbecomeD．becomes

12※第二種現(xiàn)在完成時(shí)態(tài)使用技巧

1)、這種完成時(shí)態(tài)的肯定句不與“一段時(shí)間”的時(shí)間狀語連用

常見的這類動(dòng)詞有：come,go,leave,kill,die,lose,buy,start,give,marry,join,bring,hear,etc.），因此與它連用的時(shí)間狀語不能是指“一段時(shí)間”。

①IhaveheardfrommygirlfriendsinceIcametoAmerica.（×）

②Ihaveboughtthispairofshoesforayear．（×）

③Hehaslefthishometownfor3years.（×）13這種錯(cuò)誤句子的改正有多種方式：

①Helefthishometown3yearsago.

②It’s3yearssincehelefthishometown.

③Hehasn’tcomebacksincehelefthishometown3yearsago.

④Hehasbeenawayfromhishometownfor3years.

不過，瞬間動(dòng)詞的完成時(shí)態(tài)若用否定式，表示尚未發(fā)生的事情，則可作為一種狀態(tài)，從而可以表示延續(xù)。

①Beggar：Madam,Ihaven’tseenapieceofmeatforweeks.

Lady：Mary,pleaseshowthispoormanthehamweboughtjustnow.

②Ihaven’tseenafilmforweeks.

③Ihaven’theardfrommygirlfriendsinceIcametoAmerica.

④Ihaven’tboughtapairofshoesforayear.

142).與不確定時(shí)間的時(shí)間狀語連用

這種現(xiàn)在完成時(shí)態(tài)可以不與任何時(shí)間狀語連用，也可以同一些表示不確定的時(shí)間狀語連用，如：already(已經(jīng)),yet(只用在疑問句或否定句中),lately(最近),often,just(剛剛，方才),never(從不，從未發(fā)生過)等。例如：

①A：Wouldyoulikesomethingtoeat?

B：No,thanks.I’vejusthaddinner.

②TheleadingexpertonsleepinAmericaclaimsthathehasneverseenasleepwalker.

③Hasitstoppedrainingyet?

④Hehasn’tarrivedyet.

⑤Hehasalreadyarrived.

⑥Ihaveoftenthoughtthatitwouldbeperfectifwecouldflywithoutanyaid.153).具有“新聞”性質(zhì)

①ThePresidenthasbeenassassinated.

②Hecan’tgoonholidaybecausehehasbrokenhisleg.

請(qǐng)認(rèn)真體會(huì)下面對(duì)話：

①A：Haveyouseenthefilm“ForrestGump”?

B：Yes,Ihave.

A：Whendidyouseeit?

B：Isawitlastspring.

A：Didyouseeitalone?

B：No,Isawitwithmyboyfriend.16②A：ThePresidenthasbeenassassinated.

B：Really?Whendidthathappen?

A：Hewaskilledlastnightwhenhespokeincrowd.

③A：IhearthatfamousChinesecomedianhasdied.

B：Really?Whendidshedie?

A：Shewasdeadlatelastnight.

④A：Hasthebosscomeyet?

B：Yes,hehas.Heisinhisofficenow.

A：Whendidhecome?

B：Hecameat9o’clock.Heaskedaboutyou.173、其他使用現(xiàn)在完成時(shí)的結(jié)構(gòu)

⑴This／That／Itis+序數(shù)詞+名詞+that+現(xiàn)在完成時(shí)

①ItisthethirdtimethatI’vecometoBeijing.

②Itisthefifthtimethatsomeonehasknockedatmydoor.

③—ThisisthetenthcupofcoffeethatI’vedrunkthisevening.

—Howareyougoingtobeabletofallasleeplaterifyoukeeponlikethis?

⑵This／That／Itis+最高級(jí)或only修飾名詞+現(xiàn)在完成時(shí)

①ThisisthemostinterestingmoviethatI’veeverseen.

②ThisisthebestwineIhaveeverdrunk.

③ItistheworstbookIhaveeverread.

④ThisisthehardestjobIhaveeverhad.

⑤Thisistheonlybookhehaswritten.

184、現(xiàn)在完成時(shí)與一般過去時(shí)比較

⑴現(xiàn)在完成時(shí)的第二種用法。此時(shí)完成時(shí)表示的也是過去的動(dòng)作或情況，只是當(dāng)我們強(qiáng)調(diào)過去的事情對(duì)現(xiàn)在仍有意義或仍有重要影響時(shí)才用現(xiàn)在完成時(shí)。

①Hecan’tgoonholidaybecausehehasbrokenhisleg.②Hebrokehisleg.

③Oneofyourfriendsisdrivingasportscarbutheseemstobeverynervousandnotsurewhattodo.

Youmayask:Haveyoudrivenasportscarbefore?

Hemayreply:No,thisisthefirsttimethatI’vedrivenasportscar.

④Didyoudrivetotheparty?

19

Isawthisfilmyesterday.（強(qiáng)調(diào)看的動(dòng)作發(fā)生過了。）

Ihaveseenthisfilm.（強(qiáng)調(diào)對(duì)現(xiàn)在的影響，電影的內(nèi)容已經(jīng)知道了。）

Whydidyougetupsoearly?（強(qiáng)調(diào)起床的動(dòng)作已發(fā)生過了。）

Whohasn'thandedinhispaper?

（強(qiáng)調(diào)有卷子，可能為不公平競(jìng)爭(zhēng)。）HehasbeenaLeaguememberforthreeyears.

(是團(tuán)員的狀態(tài)可持續(xù))

HejoinedtheLeaguethreeyearsago.

(三年前入團(tuán)，joined為短暫行為。)20比較：

①Ihaven’tseenhimthismorning.

②Ididn’tseehimthismorning.

③Ihavecalledhimthreetimesthismorning.

④Icalledhimthreetimesthismorning.

⑵在用于延續(xù)性動(dòng)詞時(shí)兩種時(shí)態(tài)的區(qū)別，請(qǐng)比較：

①HelivesinBeijing.Hehaslivedherefor3years.

②HelivedinBeijingfor3yearsandthenemigratedtoAmerica.

③Hehasbeeninthearmyfor6years.

④Hewasinthearmyfor6years.

⑤Ihavesmokedfor2years.

⑥Ismokedfor2years.21一、現(xiàn)在完成進(jìn)行用法：動(dòng)作發(fā)生在過去，一直延續(xù)到現(xiàn)在，并可能繼續(xù)延續(xù)下去。謂語：have/has+been+現(xiàn)在分詞221）他們整個(gè)上午在看電視。2）我一直在考慮換工作。3）我已經(jīng)等了她6個(gè)小時(shí)。4）天整整下了一個(gè)月的雨。5）我一直坐在花園里，剛剛才進(jìn)來。TheyhavebeenwatchingTVallmorning.

Ihavebeenthinkingaboutchangingmyjob.Ihavebeenwaitingforherforsixhours.

Ithasbeenrainingforawholemonthsofar.I’vebeensittinginthegarden,andhavejustcomeindoors.23現(xiàn)在完成時(shí)和現(xiàn)在完成進(jìn)行時(shí)比較1.現(xiàn)在完成時(shí)表示動(dòng)作已經(jīng)完成，而完成進(jìn)行時(shí)卻不一定如此。

I’vemadeacake.(已經(jīng)做好)I’vebeenmakingacake.(不一定做好了)He’swrittenanovel.(已經(jīng)完成)He’sbeenwritinganovel.(可能未完成)

242.現(xiàn)在完成時(shí)與forthreeyears、sincethreeyearsago等這樣的表示一段時(shí)間的時(shí)間狀語連用時(shí)，能和現(xiàn)在進(jìn)行時(shí)互換，意義差別不大。沒有這樣的時(shí)間狀語，用現(xiàn)在完成時(shí)指的是一個(gè)完成了的動(dòng)作。①Ihaveworked∕havebeenworkinginthiscompanyfor3years。

②Ihaveworkedinthiscompany.

③Ihavebeenworkinginthiscompany.④Hehasbeensleeping∕hassleptforthreehours.

⑤Hehasslept.

⑥Hehasbeensleeping.

253、完成進(jìn)行時(shí)強(qiáng)調(diào)動(dòng)作過程，完成時(shí)強(qiáng)調(diào)動(dòng)作的結(jié)果。

①M(fèi)yhandsareverydirty.I’vebeenpaintingthehouse.

②Ihavepaintedthehousegreen.Thehousewaswhite,butnowit’sgreen.

③Sorryaboutthemess—I’vebeenpaintingthehouse.

④I’vepaintedtworoomssincelunchtime.

⑤Ihavebeenreadingyourgrammarbook.AfterIfinishit,I’lldiscusssomeproblemswithyou.26二、過去完成時(shí)態(tài)1、用法：某個(gè)時(shí)間之前，某事已經(jīng)發(fā)生。即過去的過去，用過去完成時(shí)。2、謂語：haddone271）我到達(dá)時(shí)他已經(jīng)離開了。2）我一直等到他做完作業(yè)。3）她說她已經(jīng)把這件事忘了。4）當(dāng)我看見她時(shí)，她己經(jīng)結(jié)婚了。Hehadalreadyleft

bythetimeIarrived.

Iwaiteduntilhehadfinishedhishomework.Shesaidthatshehadforgottenthismatter.WhenIsawher,shehadalreadygotmarried.28過去完成時(shí)的其他用法

1）intend,mean,hope,want,plan,suppose,expect,think,propose,wish等動(dòng)詞的過去完成時(shí)可表示過去未能實(shí)現(xiàn)的計(jì)劃、設(shè)想、意圖或希望等。

①IhadplannedtogoshoppingwithyoubutmymothercametoseemejustwhenIwasabouttogo.

②Shehadhopedthathewouldcometodateher,buthedidn’tshowup.

③Ihadintendedtoseeyou,butIwasbusy.

④Theyhadhopedtoseeyouoffattheairport,buttheygottheretoolate.

292）用在“Itwasthe＋序數(shù)詞（first,second…）或最高級(jí)…that…”句型中。

例如：

LastweekIattendedaninternationalconferenceandsawMr.Machine.ItwasthethirdtimethatIhadmethim.

30過去完成進(jìn)行時(shí)用法：動(dòng)作發(fā)生在過去，一直延續(xù)到過去，并可能繼續(xù)延續(xù)下去。過去完成進(jìn)行時(shí)與過去完成時(shí)之間的關(guān)系，同現(xiàn)在完成進(jìn)行時(shí)與現(xiàn)在完成時(shí)之間的關(guān)系一樣。它的用法與現(xiàn)在完成進(jìn)行時(shí)基本相同，只是將“坐標(biāo)時(shí)問”移到過去。同樣是強(qiáng)調(diào)動(dòng)作的持續(xù)性，表示開始于過去某個(gè)時(shí)刻之前的動(dòng)作持續(xù)到過去這一時(shí)刻，并繼續(xù)持續(xù)下去。311）她說她一直在等待你的好消息。2）他給我打電話時(shí)，我已經(jīng)工作了一段時(shí)間。3）當(dāng)我到達(dá)那里時(shí)，我哥哥已經(jīng)寫了一個(gè)月論文。Shesaidthatshehadbeenexpectingyourgoodnews.Ihadbeenworkingforsometimewhenhecalledme.MyelderbrotherhadbeenwritinghisessayforonemonthbythetimeIarrivedthere.32過去完成時(shí)和過去完成進(jìn)行時(shí)過去完成時(shí)表示動(dòng)作已完成，過去完成進(jìn)行時(shí)表示動(dòng)作可能在繼續(xù)。Hehadcleanedthekitchen.Hehadbeencleaningthekitchen.Theyhadrepairedtheengine.Theyhadbeenrepairingtheengine.33三、將來完成時(shí)態(tài)（willhavedone）用法：在現(xiàn)在的將來某一時(shí)刻之前完成的動(dòng)作。謂語：shall/will+have+done（過去分詞）341）我會(huì)在你回來之前去美國(guó)。2）她會(huì)在她母親回來之前做完作業(yè)。3）他會(huì)在今天下午3點(diǎn)前到達(dá)北京。4）我會(huì)在下個(gè)月底之前寫完論文。IshallhaveleftforAmericabeforeyoucomeback.

（從句做時(shí)間狀語）Shewillhavefinishedherhomeworkbythetimeher

mothercomesback.HewillhavearrivedinBeijingbythreethisafternoon.

Bytheendofnextmonth,Ishallhavecompletedmyessay.35

說明：1）每句劃線部份均有“在未來某一時(shí)刻之前”的意思。

2）在90%的情況下，現(xiàn)在將來完成時(shí)都離不開介詞“by”（在---之前）。以下是現(xiàn)在將來完成時(shí)和過去完成時(shí)在“by”用法上的區(qū)別：

byteno’clocktomorrow（用現(xiàn)在將來完成時(shí)）

bytheendofnextmonth（用現(xiàn)在將來完成時(shí)）

bythetimehearrivesnextweek（用現(xiàn)在將來完成時(shí)）

byteno’clockyesterday（用過去完成時(shí)）

bytheendoflastmonth（用過去完成時(shí)）

bythetimehearrivedyesterday（用過去完成時(shí)）總之，“by”后面是將來的時(shí)間，就一定要用現(xiàn)在將來完成時(shí)；“by”后面是過去的時(shí)間，就一定要用過去完成時(shí)。36將來完成進(jìn)行時(shí)

用法：動(dòng)作在現(xiàn)在的將來某一時(shí)刻之前發(fā)生，但該動(dòng)作很可能繼續(xù)延續(xù)下去。謂語：shall/will+have+been+doing（現(xiàn)在分詞）將來完成進(jìn)行時(shí)的用法與現(xiàn)在完成進(jìn)行時(shí)基本相同，只是將“坐標(biāo)時(shí)間”移到將來。同樣是強(qiáng)調(diào)動(dòng)作的持續(xù)性，表示開始于將來某個(gè)時(shí)刻之前的動(dòng)作持續(xù)到將來這一時(shí)刻，并可能繼續(xù)持續(xù)下去。371）等她到達(dá)時(shí)，我可能等了她五個(gè)小時(shí)啦。2）到下個(gè)月底，她在這里生活了整整十年。3）如果明天再下雨的話，那么雨整整下了一個(gè)月。Bythetimeshearrives,Ishallhavebeenwaitingforherforfivehours.Bytheendofnextmonth,shewillhavebeenlivingherefortenyearsexactly.

Ifitrainsagaintomorrow,itwillhavebeenrainingforawholemonth.38溫故知新：InBrief

對(duì)于完成時(shí)態(tài)，首先應(yīng)該真正理解現(xiàn)在完成時(shí)態(tài)的三種思維用法：1．延續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)；2．過去發(fā)生但與現(xiàn)在仍有聯(lián)系的動(dòng)作或狀態(tài)；3．到目前為止的一個(gè)時(shí)間段內(nèi)重復(fù)發(fā)生的動(dòng)作。其他兩種完成時(shí)態(tài)在思維上與現(xiàn)在完成時(shí)本質(zhì)上是一樣的，區(qū)別只是人們說話的立足時(shí)間不同。另外要注意比較不同用法的完成時(shí)態(tài)和不同的時(shí)間狀語的搭配。39完成時(shí)與完成進(jìn)行時(shí)態(tài)的練習(xí)
