      現(xiàn)在完成時用法解析

      時間:2019-05-14 18:32:19下載本文作者:會員上傳
      簡介:寫寫幫文庫小編為你整理了多篇相關(guān)的《現(xiàn)在完成時用法解析》,但愿對你工作學(xué)習(xí)有幫助,當(dāng)然你在寫寫幫文庫還可以找到更多《現(xiàn)在完成時用法解析》。

      第一篇:現(xiàn)在完成時用法解析

      現(xiàn)在完成時用法解析

      1.構(gòu)成

      現(xiàn)在完成時是由助動詞 have(has)+動詞的過去分詞構(gòu)成。助動詞說明該謂語是屬于現(xiàn)在時范圍。它和主語的人稱、數(shù)要保持一致。過去分詞是主要的謂語動詞,說明句子的意義。

      2.用法

      (1)表示動作發(fā)生在過去某個不確定的時間,但對現(xiàn)在留下了某種影響和結(jié)果。常被just、already、yet 等副詞修飾。如:

      -Have you had lunch yet?-Yes,I have.I've just had it.你(已經(jīng))吃午飯了嗎? 我剛剛吃過。(現(xiàn)在我不餓了)

      (2)表示從過去某一時刻開始一直持續(xù)到現(xiàn)在的動作或狀態(tài)。這個動作可能剛停止,可能仍然在進行。常帶有for和since等表示一段時間的狀語。如:He has taught here since 1981

      他自1981年就在這兒教書。(可能還要繼續(xù)教)

      I have't seen her for four years.我有四年沒見到她了。

      (3)表示說話前發(fā)生過一次或多次的動作,現(xiàn)在成為一種經(jīng)驗,一般譯為漢語“過”,常帶有twice,ever,never,three times等時間狀語。

      如: I have been to Beijing twice.我去過北京二次。

      3.現(xiàn)在完成時的時間狀語

      (1)現(xiàn)在完成時屬于現(xiàn)在時范圍,故不能和過去的時間狀語連用。如:yesterday,last Sunday,in1990,three years ago等。但是,在強調(diào)動作產(chǎn)生的后果和影響時,可以和一些表示不確定的時間狀語連用。

      a.用副詞already和yet。already一般用于肯定句中,yet一般用于否定句和 疑問句中。如:We have already finished our homework.我們已完成作業(yè)了。

      They haven't finished their homework yet.他們還沒有完成作業(yè)。

      b.用ever 和never。多用于否定或疑問句中,表示“曾經(jīng)”或“從未“等。如:-Have you ever been to the Great Wall?你曾經(jīng)去過長城嗎?

      -I have never been to the Great Wall.我從未去過長城。

      c.用表示到說話為止的過去時間狀語,如just,before,up to now,the past few years等。例如:I have seen her before,but I can not remember where.我以前見過她,但記不起在哪里見過。

      He has been there three times the last few days.近幾年他去過那里三次了。

      d.用包括“現(xiàn)在”在內(nèi)的時間狀語,如:now,today,this morning(month,year,term)等。例如:-Have you met him today?-No,I haven't.今天你見過他嗎?我 沒有。

      How many times have you been there this year?

      今年你去過那里多少次?

      (2)現(xiàn)在完成時可以和帶有since或for等表示“一段時間”的狀語連用,表示動作或狀態(tài)從某一時刻開始,一直持續(xù)到現(xiàn)在。如:I haven't seen him for two years.但是,像come,arrive,buy等終止性動詞不能與表示“一段時間”的狀語連用。要用,必須改為“be(在)”等延續(xù)性動詞來表述。現(xiàn)歸納總結(jié)一下由非延續(xù)性動詞到延續(xù)性動詞的轉(zhuǎn)換:

      arrive→be here begin(start)→be on

      die →be dead come back→be back

      leave →be away fall ill(sick,asleep)→be ill(sick,asleep)

      get up→be up go out →be out

      finish →be over put on →wear 或be on

      open →be open join →be in或 be a member of…

      close →be closed go to school→be a student

      borrow →keep buy →have

      catch(a cold)→ have(a cold)get to know →know

      begin to study→study come to work→work等

      如:He has been a soldier for three years.他參軍三年了。

      His father has been dead for two years.他父親去世二年了。

      The film has been on for ten minutes.電影已開始十分鐘了。

      We have studied English for three years.我們(開始)學(xué)英語已三年了。

      4.現(xiàn)在完成時和一般過去時的區(qū)別

      現(xiàn)在完成時和一般過去時都表示在過去完成的動作。但現(xiàn)在完成時強調(diào)的是這一動作與現(xiàn)在的關(guān)系。如對現(xiàn)在產(chǎn)生的結(jié)果或影響等,而一般過去時只表示動作在過去某一時刻發(fā)生,不表示和現(xiàn)在的關(guān)系。試比較:

      I have lost my new book.我把新書丟了。(現(xiàn)在還未找到)

      I lost my new book yesterday.我昨天把新書丟了。(昨天丟的,現(xiàn)在找到與否沒說明)

      5.幾點注意事項

      (1)have been(to)與have gone(to)的區(qū)別:have been(to)表示“去過某地(現(xiàn)在已經(jīng)回來了)”,可用于各人稱;have gone(to)表示“去某地了(說話時某人不在當(dāng)?shù)?”,常用于第三人稱,前者可與once ,never,several times等連用,后者則不能。如:They have been to Beijing twice.他們?nèi)ミ^北京兩次。

      He has gone to Beijing.他去北京了。

      (2)如單純表示一段時間,或強調(diào)一段時間,雖有since一詞,也不必用完成時。如:It is two years since his father died.=His father has been dead for two years.他父親去世已有三年了。

      (3)終止性動詞現(xiàn)在完成時的否定式,已變成一種可以延續(xù)的狀態(tài),因此可以和表示一段時間的狀語連用。

      如:I haven't left here since 1997.自從1997年以來,我一直沒有離開過這兒。

      As we all know,the environmemt around us is getting worse and worse.In some places,we can't see fish swimming in the river or trees on the hills.Some people even have no clean water to drink.So I think we must do something to protect the environment.But what can we do?How to protect our environmemt ?For example,we can go to school on foot or by bike.we can use shopping baskets not plastic bags when we go shopping,and we can use both sides of the paper when we write.In a word,if everyone pays more attention to our environment,there will be less pollution and our life will be better。“There is only one earth”,I hope everyone will protect our environment well。

      2、保護環(huán)境

      (四川樂山)從2008年6月1日起,國家將禁止商家免費提供塑料袋,掀起全國“拒塑”的環(huán)保運動。假如你是李華,準(zhǔn)備以“What Can We Do for the Environment” 為題,寫一篇保護環(huán)境的英語演講稿。內(nèi)容包含:

      (1)。在購物時用布袋子替代塑料袋;(2)。盡可能地再利用使用過的課本;(3)。離開教室應(yīng)關(guān)燈;(4)。最好走路或騎自行車上學(xué);(5)。簡述理由:保護環(huán)境,減少污染,節(jié)約能源等。

      參考詞匯:布袋子cloth bag 塑料袋plastic bag 保護protect 能源energy

      污染pollution 課本textbook

      What Can We Do for the Environment

      our environment is becoming worse and worse,what can we do for the environment?I think each of us can do a little bit to help with this problem。

      The first thing we can do is to use cloth bags instead of plastic bags when we go shopping.It helps to protect the environment.The second thing we can do is to reuse the old textbooks as possible as we can.We should also never forget to turn off the lights when we leave the classrooms in order to save energy.What's more,it would be better if we walk or ride a bike to school.We should try our best to reduce pollution and waste。

      In fact,even the simplest everyday activities can make a real difference to the environment.I believe we can make the world a better place to live in。

      3.為了保護地球有限的資源,我們應(yīng)該采取什么措施呢?請根據(jù)下面的提示寫一篇約80詞的短文,短文開頭已經(jīng)給出。提示詞;1.save water,the source of life,protect drinking water,stop polluting,make full use of it;2.save electricity,crucial,turn off,other electric machines;3.save forests,useful,stop cutting down;4.recycle useful rubbish,save resources

      參考作文:

      Although the world develops much faster and better,the resources on the earth get fewer and fewer.In order to protect them,something must be done。

      Save water.Water is the source of life.No water,no life.So it's very important for us to do so.Not only should we protect drinking water and stop polluting it,but also make full use of it。

      Save electricity.It is crucial.We can't imagine what the life will be like without it.Everyone should do his best to save electricity.Don't forget to turn off lights or other electric machines when we finish working。

      Save forests.They are useful.Please stop cutting them down and use recycled paper instead.Make our world a green one to live in。

      Recycle useful rubbish.Plenty of rubbish can be recycled like cans,paper,bottles,and so on。

      We can save resources in this way.I believe we can make the world a better place to live in。與父母相處的話題類作文難度較大,掌握基本句式,背誦范文非常必要。

      Dear Alice,As a teenager,I met the same problem as you.But now I can get along better with my mother.Here are some ideas for you。

      If your mother doesn't take your advice,just keep silent and give her a smile。

      I hope what I say here can help you a lot。

      第二篇:現(xiàn)在完成時用法小結(jié)

      現(xiàn)在完成時用法小結(jié)

      (只摘抄黑體字部分,藍體字只讀不摘抄,第二種用法只學(xué)不摘抄)現(xiàn)在完成時用來表示說話之前已發(fā)生或完成的動作或狀態(tài),其結(jié)果和現(xiàn)在有聯(lián)系。動作或狀態(tài)發(fā)生在過去,但它的影響現(xiàn)在還存在;也可表示從過去開始持續(xù)到現(xiàn)在的動作或狀態(tài)。屬于現(xiàn)在時態(tài)的范疇。其構(gòu)成: 助動詞have(has)+過去分詞。

      肯定式:主語 + have/has + 過去分詞 + 其他。(當(dāng)主語是第三人稱單數(shù)時用has,其余人稱用have。過去分詞:規(guī)則動詞的過去分詞構(gòu)成與動詞過去式相同;不規(guī)則動詞需要特殊記憶。)

      否定式:主語 + haven't/hasn't + 過去分詞 + 其他。

      疑問式: Have /Has + 主語 + 過去分詞 + 其他? 簡略答語: Yes, 主語 + have/has.(肯定)No, 主語 + haven't/hasn't.(否定)

      (一)表示過去發(fā)生或完成的某一動作對現(xiàn)在造成的影響或結(jié)果。

      如: Have you read that story? 你讀過那個故事嗎?

      (“讀”這一動作發(fā)生在過去,對現(xiàn)在造成的影響是:是否知道故事的內(nèi)容。)

      I have bought two apples.

      我買了兩個蘋果。

      (“買”這一動作發(fā)生在過去,對現(xiàn)在造成的結(jié)果是:擁有兩個蘋果。)

      請朗讀下面句子,體會現(xiàn)在完成時的含義。(以下句子摘抄兩句)1.I have finished my homework.(My homework is done, I can do something else.)2.She has seen the doctor.(Now she knows what’s wrong with her.)3.They have seen the film.(Now they know what the film is about.)4.Lily has lost her pen.(Now she can’t see it.)5.Have you found your watch?(Do you have your watch now?)6.Has the train arrived?(Can we get on the train now?)7.Has Jenny invited you to her party?(Do you know her party? Will you go?)8.I haven’t borrowed a book from the library.(Now I don’t have a library book.)9.Jim hasn’t read the story.(He doesn’t know about the story.)10.I haven’t washed my clothes.(My clothes are still dirty.)請將下面句子變成否定句,一般疑問句,并做肯定否定回答,同時體會各個句子的含義,領(lǐng)悟現(xiàn)在完成時的用法。(摘抄兩個句子)1.Jim has returned the book to the library.2.I have bought a new pair of shoes.3.The students have swept the floor.4.I have told the teacher about it.5.The train has left the station.6.Jenny has turned off the lights.7.My mother has cooked supper for us.8.We have done our homework.現(xiàn)在完成時的“完成用法” 現(xiàn)在完成時的“完成用法”指的是動作發(fā)生在過去某一時刻并已結(jié)束,但該動作對現(xiàn)在產(chǎn)生了影響,與現(xiàn)在情況具有因果關(guān)系。

      現(xiàn)在完成時“完成用法”的特點是動作不延續(xù),因此,該時態(tài)只能與表示不定的時間狀語(如:already,yet,before,recently等)、頻度時間狀語(如:never,ever,once等)、包括現(xiàn)在時刻在內(nèi)的時間狀語(如:this morning / month /year...,today等)連用?,F(xiàn)在完成時的時間狀語

      (1)現(xiàn)在完成時屬于現(xiàn)在時范圍,故不能和過去的時間狀語連用。如:yesterday,last Sunday, in1990,three years ago等。

      a.用副詞already,yet和just。already“已經(jīng),”一般用于肯定句中,yet“已經(jīng),還”一般用于否定句和 疑問句中。

      如:We have already finished our homework.(We have finished our homework already.)我們已完成作業(yè)了。

      They haven't finished their homework yet.他們還沒有完成作業(yè)。

      -Have you washed your clothes yet?-No,not yet.just “剛剛”,常用于肯定句.注意,just now是過去的時間狀語,只能與過去時連用.The train has just left.(It’s not here now.)The train left just now.I have just cleaned the room.(The room is clean now.)I cleaned the room just now.b.用ever 和never。多用于否定或疑問句中,表示“曾經(jīng)”或“從未“等。如:

      -Have you ever been to the Great Wall?你曾經(jīng)去過長城嗎?

      -I have never been to the Great Wall.我從未去過長城。

      c.用表示到說話為止的過去時間狀語,如just,before,up to now,the past few years等。例如:

      I have seen her before,but I can not remember where.我以前見過她,但記不起在哪里見過。

      He has been there three times the last few days.近幾年他去過那里三次了。

      d.用包括“現(xiàn)在”在內(nèi)的時間狀語,如:now,today,thismorning(month,year, term)等。例如:-Have you met him today?-No,I haven't.今天你見過他嗎?我 沒有。

      How many times have you been there this year? 今年你去過那里多少次?

      在學(xué)習(xí)這一概念的同時,還應(yīng)注意常與現(xiàn)在完成時連用的幾個副詞:already,just,ever,yet,never等。already,just多用于肯定句中,ever,yet,never多用于疑問句和否定句中。

      如: I have already finished my homework.

      我已經(jīng)做完家庭作業(yè)了。

      He has just had his meal.

      他剛吃過飯。

      Have you ever sung this English song?

      你曾唱過這首英文歌嗎?

      They haven't started yet.

      他們還沒有動身。

      We have never heard of it. 我們從來沒有聽說過這件事。

      (以下內(nèi)容只學(xué)習(xí),不摘抄)

      (二)表示過去已經(jīng)開始,一直持續(xù)到現(xiàn)在的動作或狀態(tài)。

      1、因為表示的是持續(xù)的動作或狀態(tài),所以使用的動詞通常是延續(xù)性動詞:be, stay, study, wait, keep, have… 等;

      2、使用的時間狀語通常由for或since 引導(dǎo),但二者后接的詞有所不同:

      for后常跟一個時間段,指某個動作到現(xiàn)在為止已持續(xù)了多長時間。

      如:for three years, for half an hour等。since 作介詞,后面可以接一個時間點,如since 1980,也可以接“一段時間+ago”,如: since three years ago, since two months ago等。since 還可用作連詞,引導(dǎo)一個過去時態(tài)的時間狀語從句。

      如:We have known each other since we went to college.3、非延續(xù)性動詞不能直接和for 或since 連用,但我們可以找一個相應(yīng)的延續(xù)性動詞或動詞短語來替換這些非延續(xù)性動詞,如: become→be, come to→be in / at, go out→ be out, leave→be away(from), begin→be on, stop→ be over,buy→ have, borrow→ keep, open→be open, close→be closed, join→be a member of/be in, die→be dead, catch a cold→have a cold, get to know→know, become a teacher →be a teacher,fall asleep→be asleep, fall ill→ be ill等。

      4、句型It is the first(second, third...)time that...的that從句中,謂語動詞須用現(xiàn)在完成時,表示到說話時為止動作發(fā)生過幾次。

      如:It is the first time that I have been here.(三)現(xiàn)在完成時與一般過去時的用法比較

      1、一般過去時表示過去某個時間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動作。說話的側(cè)重點只在于陳述一件過去的事情,不強調(diào)對“現(xiàn)在”產(chǎn)生的影響。如: He visited Guilin in 1998.他1998年參觀過桂林。(只說明去桂林的時間)

      2、現(xiàn)在完成時表示動作發(fā)生在過去,對現(xiàn)在造成了影響或產(chǎn)生了結(jié)果。不與確定的過去時間狀語連用。

      如: Jill has bought a new computer.吉爾買了一臺新電腦。(著重點是現(xiàn)在有了一臺新電腦)

      3、兩種時態(tài)的區(qū)分

      (1)一般過去時的謂語動詞用過去式,而現(xiàn)在完成時的謂語基本構(gòu)成是“助動詞have /has +過去分詞”。(2)一般過去時通常與表示過去的時間狀語連用。如:yesterday, last week, two years ago, just now, in 2002等;

      而現(xiàn)在完成時則常與just, already, ever, never等副詞和these days, this week, since..., for...等表示一段時間的狀語連用。

      (3)看看以下的幾組句子,有什么區(qū)別?

      ① Have you seen the film?(A)

      Did you see the film?(B)

      [說明] 你看過這部電影嗎?(A)句強調(diào)的是被問者對劇情是否了解;(B)句強調(diào)的是看這部電影的動作是否發(fā)生過,并不強調(diào)是否知道其內(nèi)容。

      ② How has he done it?(A)

      How did he do it?(B)

      [說明]他是怎么做的這件事?(A)句強調(diào)的是他做這件事的方式對現(xiàn)在產(chǎn)生了某種影響;(B)句單純的詢問做這件事的方式。

      ③ He has lived in Beijing for 8 years.(A)

      He lived in Beijing for 8 years.(B)[說明]他在北京住了8年。(A)句講的是到目前為止他在北京住了8年,可能還會繼續(xù)在北京住下去。(B)句講的是他在北京住過8年,現(xiàn)在不在北京了。(四)幾點注意事項

      (1)have been(to)與have gone(to)的區(qū)別:have been(to)表示“去過某地(現(xiàn)在已經(jīng)回來了)”,可用于各人稱;have gone(to)表示“去某地了(說話時某人不在當(dāng)?shù)兀?,常用于第三人稱,前者可與once ,never,several times等連用,后者則不能。如:They have been to Beijing twice.他們?nèi)ミ^北京兩次。

      He has gone to Beijing.他去北京了。(2)如單純表示一段時間,或強調(diào)一段時間,雖有since一詞,也不必用完成時。如:It is two years since his father died.=His father has been dead for two years.他父親去世已有三年了。

      (3)終止性動詞現(xiàn)在完成時的否定式,已變成一種可以延續(xù)的狀態(tài),因此可以和表示一段時間的狀語連用。

      如:I haven't left here since 1997.自從1997年以來,我一直沒有離開過這兒。

      第三篇:現(xiàn)在完成時用法小結(jié)

      現(xiàn)在完成時用法小結(jié)

      現(xiàn)在完成時用來表示之前已發(fā)生或完成的動作或狀態(tài),其結(jié)果的確和現(xiàn)在有聯(lián)系。動作或狀態(tài)發(fā)生在過去 但它的影響現(xiàn)在還存在;也可表示持續(xù)到現(xiàn)在的動作或 狀態(tài)。其構(gòu)成: have(has)+過去分詞。不少同學(xué)對現(xiàn)在完成時的用法感到困惑,下面我們來對現(xiàn)在完成時的用法以及現(xiàn)在完成時與一般過去時的區(qū)別做一個詳細分析?,F(xiàn)在完成時常與不確定的過去時間狀語,如:just, yet, before, recently, once, lately等;也可以同表示瀕度的時間狀語連用,如often, ever, never, sometimes, twice, on several occasions等;也同包括現(xiàn)在時間在內(nèi)的時間狀語連用,如now, today, this morning, this year, this month等,但不能同特定的時間狀語連用(in 1993, last year等)。

      (一)表示過去發(fā)生或完成的某一動作對現(xiàn)在造成的影響或結(jié)果。

      如: Have you read that story?

      你讀過那個故事嗎?

      (“讀”這一動作發(fā)生在過去,對現(xiàn)在造成的影響是:是否知道故事的內(nèi)容。)

      I have bought two apples.

      我買了兩個蘋果。

      (“買”這一動作發(fā)生在過去,對現(xiàn)在造成的結(jié)果是:擁有兩個蘋果。)

      在學(xué)習(xí)這一概念的同時,還應(yīng)注意常與現(xiàn)在完成時連用的幾個副詞:already,just,ever,yet,never等。already,just多用于肯定句中,ever,yet,never多用于疑問句和否定句中。

      如: I have already finished my homework.我已經(jīng)做完家庭作業(yè)了。He has just had his meal.他剛吃過飯。Have you ever sung this English song?你曾唱過這首英文歌嗎? They haven't started yet.他們還沒有動身。We have never heard of it.我們從來沒有聽說過這件事。

      (二)表示過去已經(jīng)開始,一直持續(xù)到現(xiàn)在的動作或狀態(tài)。

      1、因為表示的是持續(xù)的動作或狀態(tài),所以使用的動詞通常是延續(xù)性動詞:be, stay, study, wait, keep, have… 等;

      2、使用的時間狀語通常由for或since 引導(dǎo),但二者后接的詞有所不同:

      for后常跟一個時間段,指某個動作到現(xiàn)在為止已持續(xù)了多長時間。

      如:for three years, for half an hour等。

      since 作介詞,后面可以接一個時間點,如since 1980,也可以接“一段時間+ago”,如: since three years ago, since two months ago等。

      since 還可用作連詞,引導(dǎo)一個過去時態(tài)的時間狀語從句。

      如:We have known each other since we went to college.3、非延續(xù)性動詞不能直接和for 或since 連用,但我們可以找一個相應(yīng)的延續(xù)性動詞或動詞短語來替換這些非延續(xù)性動詞,如: come→be, come to→be in / at, go out→ be out, leave→be away,begin→be on, stop→ be over,buy→ have, borrow→ keep,open→be open, close→be closed, join→be a member of,die→be dead, catch a cold→have a cold, get to know→know,become a teacher →be a teacher, fall asleep→be asleep, fall ill→ be ill等。

      4、句型It is the first(second, third...)time that...的that從句中,謂語動詞須用現(xiàn)在完成時,表示到說話時為止動作發(fā)生過幾次。

      如:It is the first time that I have been here.用于This/That/It is the first(second…)time that…句型中。如:

      It is the first time that I have visited your beautiful city.這是我第三次參觀這個美麗的城市了。

      ■用于This/That/It is +the+形容詞最高級+名詞+that…句型中用在“It(This)is(will be)the first/second/third…time+ that從句”中

      在這種從句中,當(dāng)主句動詞為is/will be時,that-從句的動詞用現(xiàn)在完成時,that 可以省略。主句中的主語還可用this, this evening等;這種結(jié)構(gòu)中的first也可用其他序數(shù)詞;time也可由其他名詞替代。

      -Do you know our town at all?你對我們城鎮(zhèn)熟悉嗎?

      -No, this is the first time I have been here.不熟,這是我第一次來這里。

      It's the first time I've been here.這是我第一次到這里來。

      It'll be the first time I've spoken in public.這將是我第一次當(dāng)眾講話。That’s the most interesting book I’ve ever read.這是我看過的最有意思的書。

      It(This)is the best(worst, most interesting等)+ 名詞+從句”結(jié)構(gòu)中的從句要求用現(xiàn)在完成時

      This is the best film I’ve ever seen.這是我所看過得最好的一部電影。

      This is the most interesting novel he has ever written.這是他寫得最好的一部小說。

      (三)現(xiàn)在完成時與一般過去時的用法比較

      1、一般過去時表示過去某個時間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動作。說話的側(cè)重點只在于陳述一件過去的事情,不強調(diào)對“現(xiàn)在”產(chǎn)生的影響。

      如: He visited Guilin in 1998.他1998年參觀過桂林。(只說明去桂林的時間)

      2、現(xiàn)在完成時表示動作發(fā)生在過去,對現(xiàn)在造成了影響或產(chǎn)生了結(jié)果。不與確定的過去時間狀語連用。

      如: Jill has bought a new computer.吉爾買了一臺新電腦。(著重點是現(xiàn)在有了一臺新電腦)

      3、兩種時態(tài)的區(qū)分

      (1)一般過去時的謂語動詞用過去式,而現(xiàn)在完成時的謂語基本構(gòu)成是“助動詞have /has +過去分詞”。

      (2)一般過去時通常與表示過去的時間狀語連用。如:yesterday, last week, two years ago, just now, in 2002等;

      而現(xiàn)在完成時則常與just, already, ever, never等副詞和these days, this week, since..., for...等表示一段時間的狀語連用。

      (3)看看以下的幾組句子,有什么區(qū)別?

      ① Have you seen the film?(A)

      Did you see the film?(B)[說明] 你看過這部電影嗎?(A)句強調(diào)的是被問者對劇情是否了解;(B)句強調(diào)的是看這部電影的動作是否發(fā)生過,并不強調(diào)是否知道其內(nèi)容。

      ② How has he done it?(A)

      How did he do it?(B)

      [說明]他是怎么做的這件事?(A)句強調(diào)的是他做這件事的方式對現(xiàn)在產(chǎn)生了某種影響;(B)句單純的詢問做這件事的方式。

      ③ He has lived in Beijing for 8 years.(A)

      He lived in Beijing for 8 years.(B)

      [說明]他在北京住了8年。(A)句講的是到目前為止他在北京住了8年,可能還會繼續(xù)在北京住下去。(B)句講的是他在北京住過8年,現(xiàn)在不在北京了。

      5.幾點注意事項

      (1)have been(to)與have gone(to)的區(qū)別:have been(to)表示“去過某地(現(xiàn)在已經(jīng)回來了)”,可用于各人稱;have gone(to)表示“去某地了(說話時某人不在當(dāng)?shù)?”,常用于第三人稱,前者可與once ,never,several times等連用,后者則不能。如:They have been to Beijing twice.他們?nèi)ミ^北京兩次。

      He has gone to Beijing.他去北京了。

      (2)如單純表示一段時間,或強調(diào)一段時間,雖有since一詞,也不必用完成時。如:It is two years since his father died.=His father has been dead for two years.他父親去世已有三年了。

      (3)終止性動詞現(xiàn)在完成時的否定式,已變成一種可以延續(xù)的狀態(tài),因此可以和表示一段時間的狀語連用。

      如:I haven't left here since 1997.自從1997年以來,我一直沒有離開過這兒。

      (2)現(xiàn)在完成時常見兩種句型: ①主語+have / has been+for短語 ②It is+一段時間+ since從句 例如:He has been in the League for three years.或It is three years since he joined the League.他入團已三年了。在表達一個在過去開始而現(xiàn)在仍在繼續(xù)或剛剛結(jié)束的動作時,某些動詞既可以用現(xiàn)在完成時,也可以用現(xiàn)在完成進行時。這樣的動詞有expect,hope,learn,lie,live,look,rain,sleep,sit,snow,stand,stay,study,teach,wait,want,work等 How long have you learnt English?你學(xué)習(xí)英語多久了? How long have you been learning English?(譯文同上。)He has slept for ten hours.他已經(jīng)睡了十個小時了。He has been sleeping for ten hours.(譯文同上。)It has snowed for a long time.雪下了好長時間了。It has been snowing for a long time.(譯文同上。)沒有進行式的動詞不可能有這樣的用法,即現(xiàn)在完成進行時不能代替以下例句中的現(xiàn)在完成時:

      They’ve always had a big garden.他們一直有一座大花園。How long have you known that?你知道這事多久了? He’s been in hospital since his accident. 他從發(fā)生事故之后,一直在醫(yī)院里。注意:現(xiàn)在完成進行時可以和時間短語連用,也可以不連用,這一點就有別于現(xiàn)在完成時,因為后者與像for six days,since June,never等一些時間短語連用才能表示這類動作。不用這些時間狀語時,現(xiàn)在完成時指的是完成了的一個動作。

      B 用現(xiàn)在完成時表示的反復(fù)的動作,有時可以作為連續(xù)的動作用現(xiàn)在完成進行時表示: I’ve written six letters since breakfast.早飯后我已經(jīng)寫了六封信。I’ve been writing letters since breakfast.早飯后我一直在寫信。I have knocked five times.I don’t think anyone’s in. 我敲了五次門。我想屋里沒有人。

      I’ve been knocking.I don’t think anybody’s in. 我一直在敲門。我想屋里沒有人

      現(xiàn)在完成進行時與現(xiàn)在完成時的區(qū)別

      (1)現(xiàn)在完成時可以表示一個已經(jīng)完成的動作,而現(xiàn)在完成進行時則表示一個正在進行的動作:

      I have read the book.我讀過這本書。I have been reading the book.我一直在讀這本書。

      【注】有少數(shù)動詞(如work, study, live, teach, stay等)在表示持續(xù)一時間時用這兩種時態(tài)含義差不多(只是用現(xiàn)在完成進行進更強調(diào)動作的持續(xù)性):

      How long have you worked [been working] here? 你在這兒工作多久了?

      I’ve lived [been living] here since 1988.自1988年以來我就一直住在這兒。

      (2)現(xiàn)在完成時通常只陳述事實,而現(xiàn)在完成進行時還可表示一種感****彩:

      I have waited for two hours.我等了兩小時。(陳述事實)

      I have been waiting for two hours.我等了兩個小時。(等得好辛苦)

      (3)現(xiàn)在完成進行時通常用來談?wù)撦^短暫的動作或情況,若要談?wù)摃r間延續(xù)較長的動作或情況或永久性情況,則通常用現(xiàn)在完成時:He has lived in Paris.他(一直)住在巴黎。He has been living in Paris.他(目前)住在巴黎。(表暫時性)

      (4)不用于進行時態(tài)的動詞通常也不用于現(xiàn)在完成進行時,但它們可以用于現(xiàn)在完成時:

      I’ve only known her for two day.我認(rèn)識她剛剛兩天。They’ve been married for twenty years.他們結(jié)婚已二十年了。The war has lasted for a long time.這場戰(zhàn)爭持續(xù)了很長時間。

      (5)現(xiàn)在完成進行時不用于被動語態(tài),若要用可用現(xiàn)在完成時的被動語態(tài)代替:

      The house has been painted for a month.這房子已漆了一個月。The problem has been studied for five days.這個問題已研究了五天

      第四篇:一般過去時,現(xiàn)在完成時,過去完成時的用法及區(qū)別

      ① 一般過去時的基本用法

      a)表示過去某個特定時間發(fā)生的動作或存在的狀態(tài)。常與過去時間連用.a moment ago(剛才),yesterday morning,last night/ week,the day before yesterday(前天),just now(剛才)等。

      He suddenly fell ill yesterday.昨天他突然生病了。

      b)表示過去經(jīng)常發(fā)生的動作或存在的狀態(tài)。

      I wrote home once a week at college.我上大學(xué)時每周給家里寫一封信.c)表示過去連續(xù)發(fā)生的一系列動作。

      She entered the room, picked up a magazine and looked through it carefully.她走進房間,拿起一本雜志,認(rèn)真地翻閱了起來。

      d)在時間、條件狀語從句中用一般過去時代替過去將來時.We would not leave until the teacher came back.老師回來我們才會離開。

      ②一般過去時的特殊用法

      a)在虛擬語氣中表示現(xiàn)在或?qū)頃r間的動作或狀態(tài)。

      I wish I were twenty years younger.但愿我年輕20歲。

      b)在口語中,一般過去時往往顯示委婉客氣

      Might I come and see you tonight?

      我想今晚來看你,好嗎?

      現(xiàn)在完成時的用法:

      1)表示過去發(fā)生或已完成的某個動作對現(xiàn)在產(chǎn)生的影響或結(jié)果,強調(diào)的是這個影響或結(jié)果,一般不與過去時間連用,常同already, just, yet等狀語連用

      例:I have just turned off the light.我剛剛把燈關(guān)上。(結(jié)果是燈已經(jīng)關(guān)上了)She has lost her bike.她把自行車丟了。(影響是他現(xiàn)在沒有自行車騎了)

      2)表示開始于過去、持續(xù)到現(xiàn)在的動作或狀態(tài),并可能繼續(xù)下去(也可能不繼續(xù)下去),常同包括現(xiàn)在在內(nèi)的時間狀語連,也同“for+時間段”或“since+時間點”的狀語連用She has taught in the school for ten years.她在這所學(xué)校教書已經(jīng)10年了。

      I haven’t eaten anything since breakfast.我從早飯起就一直沒有吃東西。

      3)表示從過去某一時間到說話時這段時間中反復(fù)發(fā)生的動作或多次動作的總和,常同頻度副詞always, often, seldom, never等連用

      I have been to the Great Wall twice.我曾經(jīng)去過長城兩次

      過去完成時用法:

      1.表示過去某一時間或動作之前已經(jīng)發(fā)生或完成的動作或存在的狀態(tài)。表示的是“過去的過去,常用的時間狀語有:”by + 過去的時間點、by the end of + 過去的時間點、before + 過去的時間點。

      Most of the guests had left when he arrived at the party.當(dāng)他到達晚會時,他發(fā)現(xiàn)大多數(shù)客人已經(jīng)離開了。

      2.過去完成時還可表示過去某一時刻之前發(fā)生的動作或狀態(tài)持續(xù)到過去某個時間或持續(xù)下去,常與for,since等詞連用。例如:

      When Jack arrived, he learned Mary had been away for almost an hour.當(dāng)杰克到時,他得知瑪麗已經(jīng)離開快一個小時了。

      4.某些動詞的過去完成時表示過去未實現(xiàn)的希望、計劃或打算。常用的動詞有hope,expect,suppose,think,want,wish等。例如:

      They had hoped to be able to arrive before ten.他們本來打算能在10點之前到達達一、一般過去時與現(xiàn)在完成時的用法比較。

      1.“一般過去時”所關(guān)心的是過去之事,與現(xiàn)在無聯(lián)系,常帶有表示過去某個時間的狀語;現(xiàn)在完成時所關(guān)心的是過去發(fā)生的事,對現(xiàn)在產(chǎn)生某種結(jié)果,強調(diào)過去與現(xiàn)在的聯(lián)系。一般不與過去具體時間連用。當(dāng)需要指明過去一個特定的時刻發(fā)生的事情時,需要使用一般過去式。

      A.I ________(lose)my pen.Can you lend me yours?

      B.Why don't you buy one?

      A.It _______(fall)into the river only a moment ago when I washed my hands.Now I've got to fill in a form with a pen.2.現(xiàn)在完成時與for或since引起的短語連用時,表達從過去開始的動作或狀態(tài)延續(xù)至今,而一般過去時與“for+一段時間”連用時,只指過去的動作或狀態(tài)在過去延續(xù)了多長時間。

      We___________(stay)here for three weeks.I think we are going to stay another two weeks.(說話時人還在)

      He __________(stay)here for three weeks last year.(并不表示現(xiàn)在是否在)

      3.一般過去時帶有表示過去某時刻的時間狀態(tài),如yesterday,last year(month,week,night),in 1980…

      I ______(come)the day before yesterday.4.現(xiàn)在完成時所帶時間狀語包含說話時在內(nèi),如today,this week(month,year),these days(years)或與說話時非常接近,如recently,just,in(during)the past three years。Great changes _______(take)place in the last ten years

      5如果一件事情發(fā)生在過去并且延續(xù)到說話的這個時刻,就需要使用現(xiàn)在完成時。They have lived here for a long time

      6一般過去時比現(xiàn)在完成時更能表達事情的結(jié)果

      John has taught math for twenty years.保留了約翰繼續(xù)教數(shù)學(xué)的可能性

      John taught math for twenty years.表明約翰已經(jīng)不再教數(shù)學(xué)了,他可能退休了,換工作了,或者去世了。

      7如果一件事情發(fā)生在過去并且延續(xù)到說話的這個時刻,就需要使用現(xiàn)在完成時。They have lived here for a long time.他們在這里已經(jīng)生活了很長一段時間。

      二、一般過去式與過去完成時的區(qū)別。

      1.一般現(xiàn)在時表示過去某一時間內(nèi)發(fā)生的動作或存在的狀態(tài),而過去完成時則表示過去某一動作或時間之前發(fā)生的動作或存在的狀態(tài)。一般過去時與現(xiàn)在相比,強調(diào)“過去”,而過去完成時則與過去相比,強調(diào)“過去的過去”。

      我們來比較下列句子:

      The meeting _________(start)at six o'clock./ start的動作發(fā)生在at six o'clock。The meeting ___________(start)when we arrived at the hall./ start的動作發(fā)生在過去的動作arrived之前。

      過去完成時與現(xiàn)在完成時的區(qū)別

      現(xiàn)在完成時表示的動作發(fā)生在過去,以現(xiàn)在的時間為基點,但側(cè)重對現(xiàn)在產(chǎn)生的結(jié)果或造成的影響,與現(xiàn)在有關(guān)。過去完成時則是一個相對的時態(tài),以過去時間為基點,它所表示的動作不僅發(fā)生在過去,更強調(diào)“過去的過去”,只有和過去某時或某動作相比較時,才用到它。比較:I have learned 1000 English words so far.到目前為止我已經(jīng)學(xué)會了 1000 個英語單詞。I had learned 1000 English words till then.到那時為止我已經(jīng)學(xué)會了 1000 個英語單詞。

      第五篇:現(xiàn)在完成時的六個要點解析教案

      現(xiàn)在完成時的六個要點解析教案

      威寧四中

      江水金

      現(xiàn)在完成時是初中英語中最重要也是最難掌握的一個時態(tài),同時它也是中考英語中一個最重要的時態(tài)考點,許多同學(xué)們對現(xiàn)在完成的用法似懂非懂,具體做題時也往往是跟著感覺走。本文結(jié)合初中英語的教學(xué)內(nèi)容和中考英語的考查特點,為同學(xué)們歸納學(xué)好定語從句必須注意的五個方面,供大家參考。

      一、弄清基本構(gòu)成方法

      現(xiàn)在完成時由“have / has+過去分詞”構(gòu)成。其中的have / has 為助動詞,構(gòu)成疑問句時,可將其提前;構(gòu)成否定句時,可直接在其后加not。

      二、掌握兩種主要用法

      現(xiàn)在完成時主要有兩種用法,一種是已完成用法,也叫影響性用法;另一種是未完成用法,也叫持續(xù)性用法。兩種用法的特點是:

      1.已完成用法(影響性用法):該用法的現(xiàn)在完成時表示一個過去發(fā)生的動作在過去已經(jīng)完成,并且這個過去發(fā)生并完成的動作對現(xiàn)在有影響或結(jié)果,同時說話強調(diào)的或感興趣的就是這個影響或結(jié)果。如:

      She has left.她離開了。(對現(xiàn)在的影響或結(jié)果:她現(xiàn)在不在這兒。)Has she found her car key? 她找到她的車鑰匙了嗎?(對現(xiàn)在的影響或結(jié)果:她能開她的車了嗎?)I have finished my work.我的工作做完了。(對現(xiàn)在的影響或結(jié)果:現(xiàn)在我沒事了。)He has eaten nothing today.他今天什么也沒吃。(對現(xiàn)在的影響或結(jié)果:他現(xiàn)在一定很餓。)2.未完成用法(持續(xù)性用法):該用法的現(xiàn)在完成時表示一個過去發(fā)生的動作并未在過去完成,而是一直持續(xù)到現(xiàn)在,并且有可能繼續(xù)下去(也可能到此結(jié)束)。如: How have you been? 你近來怎樣? She has been a teacher for 20 years.她已當(dāng)了20年的老師。How long have you lived here? 你在這里住了多久了? They have been married for ten years.他們結(jié)婚已經(jīng)10年了。I’ve known her for a long time.我認(rèn)識她很長時間了。

      注:除以上用法外,現(xiàn)在完成時還可表示過去的重復(fù)動作甚至將來動作。如: He has always gone to work by bike.他總是騎自行車上班。

      I’ll go to bed when I’ve finished my homework.我做完作業(yè)后就上床睡覺了。

      三、注意通常連用的副詞

      現(xiàn)在完成時通常連用的副詞有already, never, ever, just, before, recently等。如: We have finished our work already.我們已經(jīng)完成了工作。He has never driven a car before.他過去從未開過車。Have you ever been a teacher? 你當(dāng)過教師嗎? She’s just been to a party.她剛參加一個晚會回來。I’ve just had some photos taken.我剛照了幾張相。

      但是,若不強調(diào)動作對現(xiàn)在的影響,這些副詞也可用一般過去時。如: He just arrived in Japan.他剛到日本。

      Such things didn’t happen before.那樣的事以前沒有發(fā)生過。I hear that he went abroad recently.我聽說他最近出國了。

      四、注意since與現(xiàn)在完成時的關(guān)系

      since不管用作介詞、連詞還是副詞,句子(主句)謂語通常都用現(xiàn)在完成時。如: I haven’t seen her since last week.自上周以來我一直未見過她 I met him in 1975 and haven't seen him since.1975年我見過他,但自那以后就一直未見到他。We have been good friends since we met at school.自從讀書相識以來,我們一直是好朋友。注:表示時間長度時,通常用一般現(xiàn)在時代替現(xiàn)在完成時。如: It’s a long time since I met you last.好久不見了。

      It’s about six months since we arrived here.我們到這里大約有半年了。

      五、注意現(xiàn)在完成時與一般過去時的區(qū)別

      現(xiàn)在完成時的已完成用法很容易與一般過去時相混淆,其區(qū)別是:前者強調(diào)對現(xiàn)在的影響和結(jié)果,后者不強調(diào)這個影響和結(jié)果,而是強調(diào)這個動作發(fā)生的時間是在過去。如:

      I’ve lived here for ten years.我在這里住了10年。(現(xiàn)在仍住這兒)I lived here for ten years.我在這里住過10年。(現(xiàn)在不住這兒了)Has he got up? 他起來了嗎?(著眼現(xiàn)在情況)Did you get up very early? 你起來很早嗎?(著眼動作本身)I’ve got no news from him.我沒聽到他的消息。(不知道他的情況怎樣)I got the news from Jim.這消息我是從吉姆那聽來的。(單純談?wù)搫幼?

      六、掌握have been to 和have gone to的用法區(qū)別

      兩者均可后接地點,前者表示去過某地,通??膳c表示次數(shù)的狀語連用;后者表示到某地去了,強調(diào)說話的當(dāng)時去某地的人不在場。比較: She has been to Europe twice.她到歐洲去過兩次。

      She has gone to Europe.她到歐洲去了。(即現(xiàn)在不在這兒)注:若其后不是接名詞,而是接副詞,則不用to。如: He has been abroad many times.他多次出國。He has gone home.他回家去了。
