現(xiàn)在完成時與一般過去時的比較

1）一般過去時表示過去某時發(fā)生的動作或單純敘述過去的事情，強調(diào)動作；

現(xiàn)在完成時為過去發(fā)生的，強調(diào)過去的事情對現(xiàn)在的影響，強調(diào)的是影響。Isawthisfilmyesterday.

（強調(diào)看的動作發(fā)生過了。）Ihaveseenthisfilm.

（強調(diào)對現(xiàn)在的影響，電影的內(nèi)容已經(jīng)知道了。）2）一般過去時

常與具體的表示過去的時間狀語連用;

現(xiàn)在完成時通常與模糊的時間狀語連用，或無時間狀語。一般過去時的時間狀語:

yesterday,lastweek，…ago,in1990,inOctober,justnow,…--具體的時間狀語

現(xiàn)在完成時的時間狀語:

for,since,sofar,ever,never,just,yet,till/until,uptonow,inthepastfewyears,recently,…--模糊的時間狀語句子中如有過去時的時間副詞（如yesterday,last,week,in1960）時，不能使用現(xiàn)在完成時，要用過去時

（錯）Tomhaswrittenalettertohisparentslastnight.

（對）Tomwrotealettertohisparentslastnight.3）現(xiàn)在完成時可表示持續(xù)到現(xiàn)在的動作或狀態(tài)，動詞一般是延續(xù)性的，如live,teach,learn,work,study,know.

一般過去時常用的非持續(xù)性動詞有come,go,leave,start,die,finish,become,getmarried等。

ShejoinedtheLeaguethreeyearsago.(加入的動作不是延續(xù)的)

ShehasbeenintheLeagueforthreeyears(sincethreeyearsago).(在團內(nèi)的狀態(tài)可延續(xù))

ShehasbeenaLeaguememberforthreeyears(sincethreeyearsago).

(是團員的狀態(tài)可持續(xù))

延續(xù)動詞表示經(jīng)驗、經(jīng)歷；瞬間動詞表示行為的結(jié)果，不能與表示一段時間的狀語連用。比較延續(xù)動詞與瞬間動詞

Hehasfinishedthework.他已完成了那項工作。(表結(jié)果)

I’veknownhimsincethen.我從那時起就認識他了。(表經(jīng)歷)borrowkeep營業(yè)時間：7:00am-8:00pmopenbeopen

英語中行為動詞根據(jù)詞義可分為兩種，一種是延續(xù)性的，如teach,study,learn,live等。一種是非延續(xù)性的，如open,close,die,buy,leave,come等，表示動作的發(fā)生與結(jié)束于一瞬間完成，不能再延續(xù)，所以它的現(xiàn)在完成時不能和表示延續(xù)的時間狀語連用，即不能與表示一段時間的狀語，for+時間段,since+時間點/從句連用，也不能用在howlong引導(dǎo)的特殊疑問句中。常見瞬間動詞巧記：開始離去，借來還，（begin,leave,go,borrow,come,return）出生入死，買到家。(join,die,buy,arrive)常見非延續(xù)性動詞與延續(xù)性動詞之間的轉(zhuǎn)換：open-------2.die--------start/begin-------4.finish--------getup------6.become------join-----8.leave-----fallill/asleep----10.arrive/come/goto---11.borrow-----12.buy------beopenbein/atbeonhavekeepbeupbeill/asleepbeamember/beinbeawayfrombebeoverbedead請你來找茬兒：1.Thefilmhasbegunforfiveminutes.2.Hismotherhasdiedsincetwoyearsago.3.Ihaveboughtthecomputerforalongtime.4.HelenhasjoinedtheYouthLeaguesince2000.5.Howlonghaveyoufallenill?beenonbeendeadhadbeeninbeenill實力測驗根據(jù)提示填空He____________(離開)foranhour.I________(到達)atthestationforfiveminutes.--MayI______(借)yourdictionary?--Sorry,I_________(借)ittoMary.--when____she_____(借)it?--Twodaysago，she________itfortwodays.4.Thefactory____________(開業(yè))sincelastyear.5.We__________(參加)theYouthLeaguefortwoyears.6.Thedog____________(死)since3daysago.7.Thefilm___________(開始)forfiveminutes.8.Howlong_____you_________(待在)inLondon?hasbeenawayhavebeenborrowhasbeenopenhavebeeninhasbeendeadhasbeenonhavebeen/stayedhavelentborrowdidhaskept活動:

have/hasbeeninhave/hasgoneto:已經(jīng)去了或在途中，還沒有返回；have/hasbeento:曾經(jīng)去過某地，現(xiàn)在已經(jīng)回來了,后面可接表示“次數(shù)”的狀語;have/hasbeenin:表示某人“已在某地停留一段時間，現(xiàn)仍在那里”，其后常帶表示一段時間的狀語。ExercisesTom在哪兒？他去書店買書了。我在北京待了5年了。Jack去過上海兩次了-WhereisTom?-Hehasgonetothebookshoptobuysomebooks.IhavebeeninBeijingfor5years.JackhasbeentoShanghaitwice.HewenttoShanghailastweek.

他(曾經(jīng))到/去過上海

[在他人生中曾經(jīng)有過這樣的經(jīng)歷,但他人現(xiàn)在肯定不是在上海而是回來了]他已經(jīng)去上海了
