時態講解

壹、壹般現在時主要用於:

1 、表示經常性或習慣性動作。 e.g. It seldom snows here.

2 、表示現在的特征或狀態。 e.g. He is always ready to help others.

3 、普遍真理。 e.g. Action speaks louder than words.

4 、劇情圖片介紹,背景說明,動作解說。 e.g. (Tom enters the room and sits at the table)

Doctor : What's your trouble, young man?

Tom : I've caught a cold, doctor.

5 、時間、條件、讓步、方式狀語從句表將要發生的動作時。

與這壹時態連用的時間狀語有: already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語,連詞 since 引導的時間狀語從句。

壹般過去時與現在完成時的區別:

壹般過去時:重在說明動作在過去發生時的具體情況(時間、地點、方式、對象、細節等)。

現在完成時:只提起已發生的動作(事實)及其影響,不說明動作發生時的具體情況。

cf. Have you had your lunch? What did you have for lunch?

I have ever been to the Great Wall, and I went there last summer with my father.

註:現在完成時表達的動作常具有反復性,故下面壹句是錯的:

Have you seen the six thirty's news program? 應改為: Did you see the six thirty's news program?

四、現在完成進行時主要用於:表示過去開始的某壹動作壹直持續到現在,以至延伸到將來,它強調動作延續時間之長久。e.g. I've been writing an article. 我壹直在寫壹篇文章。(還在寫)

cf. I've written an article. 我寫了壹篇文章。(已寫完)

It has been raining these days. 這些天壹直在下雨。

五、過去完成時

1 、過去完成時是壹個相對時態,表示過去的過去,只有在兩個過去發生的動作相比較時才可顯示出來。

e.g. As soon as we got to the station, the train had left.

註:主從句表達的動作緊接時,即兩動作發生的時間沒有明顯時間上的懸殊或空檔時,主從句都可用壹般過去時。 e.g. Where did your brother study before he joined the army?

2 、過去完成時可表示截止過去某壹時間動作的總或動作的結束。

e.g. By the end of last month. We had reviewed four books By eight o'clock, he had finished his homework.

與這個時態連用的時間狀語常有: by 1985, by eight o'clock, by then, by the end of last month, by the time when, when, as soon as, before 等連詞引導的時間狀語從句,表示主句動作結束的時間。

(六)現在進行時主要用於:

1 、表示現在或現階段正在進行的動作。 e.g. Listen, someone is crying. What are you doing these days?

2 、代替壹般現在時,表示經常性動作或狀態,而含有某種感情色彩。

e.g. How are you feeling today? 妳今天感覺怎樣?(顯得親切)

He is doing well in his lessons. 他的功課很好。(贊揚)

You are always boasting. 妳老愛吹牛。(厭煩)

3 、動詞 go, come, leave, arrive 等表將要發生的動作時。 e.g. They are leaving for Shanghai.

與這種時態連用的時間狀語常有: now, these days, recently, this week 等。

七、過去進行時主要用於: 表示過去某個時刻或階段正在進行的動作。

e.g. At that time she was working in a PLA unit. 那時她在解放軍某部工作。

What were you doing this time yesterday?

用 when 引導的時間狀語從句表示主句的動作正在進行的時間。

e.g. When he came in, I was reading a newspaper.

註:

1 、 while 引導時間狀語從句敘述過去的動作時,從句常用過去進行時。

e.g. I read a magazine while I was waiting for the bus.

2 、 when 用作並列連詞,意為“這時”,連接兩分句時,第壹句多用過去進行時。

e.g. I was reading a newspaper when he came in.

壹般過去時與過去進行時的區別:

壹般過去時:強調過去某壹時間開始或完成的動作。

過去進行時:強調過去某壹時間正在進行的動作。

試區別下面兩句:

We were building a reservoir last winter. 去年冬天我們在修建壹座水庫。(可能尚未建成)

We built a reservoir last winter. 去年冬天我們修建了壹座水庫。(已經建成)

八、壹般將來時主要用於: 表示將要發生的動作或情況

e.g. Tom will have a bike of his own.

與這個時態連用的時間狀語常用: tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。

壹般將來時態與其它結構表將來情況的區別:

壹般將來時態 :主要從時間的角度表將要發生的動作或情況。

be going to 結構 :①表(主觀上)打算或準備做某事時。 ②表有發生某事的預兆時。

e.g. They are going to have a competition with us in studies. It is going to rain.

據以上區別,故下面壹句是錯的:

I am going to be eighteen years old next year. 應改為: I shall be eighteen years old next year.

be about to do sth 結構 :意為“剛要做某事”、“馬上要做某事”強調時間之緊迫性。

e.g. We are about to discuss this problem. 我們將馬上討論這個問題。

be to do sth 結構: 表示按計劃、安排、規定將實施某事或表示註定會發生某事。

e.g. When is the train to leave. All these things are to be answered for.

及物動詞與不及物動詞

英語中按動詞後可否直接跟賓語,可把動詞分成及物動詞與和及物動詞。

1.及物動詞: 字典裏詞後標有vt. 的就是及物動詞。及物動詞後必須跟有動作的對象(即賓語),可直接跟賓語。see 看見 (vt.) +賓語 I can see a boy.

2.不及物動詞:字典裏詞後標有vi. 的就是不及物動詞。不及物動詞後不能直接跟有動作的對象(即賓語)。若要跟賓語,必須先在其後添加上某個介詞,如to,of ,at後方可跟上賓語。

具體每個動詞後究竟加什麽介詞就得背動詞短語了,如listen to,look at…..

3. 賓語(動作的對象):是名詞或代詞,或相當於名詞的詞或短語(如動名詞)。其它詞不看作動作的對象呢。

4.舉例:“看”

(1)see 看見 (vt.) +賓語 I can see a boy.

(2)look 看 (vi.) x賓語(即不能直接加賓語). Look! She is singing.

Look carefully! (註意:carefully 是副詞,不是名詞,故不作賓語喲)

(3)look at 看…….+賓語 Look at me carefully! (me是代詞,作賓語了)

連系動詞

連系動詞本身有壹定的詞義,但不能獨立作謂語,必須與表語壹起構成謂語。

表語通常由名詞、形容詞,或相當於名詞或形容詞的詞或短語等充當,說明主語是什麽或怎麽樣。

壹、 連系動詞的類型有:

1. "存在"類:表示存在或具有某種特征或狀態.這類連系動詞強調"存在"。常見的有:be(是),look(看起來),feel(摸上去),seem(似乎是),appear(似乎、顯得),prove(證明是),smell(聞起來),taste(嘗起來),sound(聽起來)等。例如:

The story sounds true.

Those oranges taste good.

2. "持續"類:表示某種情況或狀態的持續。這類連系動詞強調"持續"。常見的有:remain(依然),keep(保持),stay(保持),continue(繼續、仍舊),stand(處於某狀況或情形)等。例如:

Why don't you put the meat in the fridge? It will stay fresh for several days.

It's already ten in the morning. The store remains closed. What's the matter?

3. "變化"類:表示由壹種情況或狀態變化成另壹種情況或狀態。這類連系動詞強調"變化"後的情況或狀態.常見的有:become(變成), turn(變成), grow(變得), go(變得)等。例如:

Put the fish in the fridge, or it will go bad in hot weather.

二、註意事項

1. 有些連系動詞通常不用於被動語態和進行時態中。如:feel, taste等詞。例如:

-Do you like the material?

-Yes, it feels very soft.

2. 壹般情況下,連系動詞主要跟形容詞或分詞作表語。例如:

Be careful when you cross this very busy street. If not, you may get run over by a car.

3. 能跟名詞作表語的連系動詞常見的有:be, become, appear, seem, prove, remain和turn等.註意:turn後跟(表示主語身份的)名詞作表語時,不加冠詞。例如:

Twenty years later, he turned teacher.

The population growth in China remains a problem.

4. 連系動詞也可跟不定式(to do / to be),常見的有:appear, seem, remain, prove, look等。例如:

Having a trip abroad is certainly good for the old couple, but it remains to be seen whether they will enjoy it.

On the long journey, Peter proved to be a most interesting guide. We all had a wonderful time.

終止性動詞與延續性動詞

終止性動詞指不會持續壹段時間的動作,即動作在瞬間或短時間內完成。 例如:get arrive 這類動詞不與壹段時間連用

終止性動詞:表示不能延續的動作,即動作發生後立即結束。如:begin,arrive, borrow, ...終止性動詞的肯定式是不能持續的,所以不能和表示壹段時間的狀語連用,而終止性的否定式就可以和表壹段時間的狀語.

壹、延續性動詞和終止性動詞的概念

英語中,動詞按其動作發生的方式、動作發生過程的長短,可分為延續性動詞和終止性動詞。

延續性動詞表示能夠延續的動作,這種動作可以延續下去或產生持久影響。如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。

終止性動詞也稱非延續性動詞、瞬間動詞或短暫性動詞,表示不能延續的動作,這種動作發生後立即結束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。

二、延續性動詞的用法特征

1.延續性動詞可以用於現在完成時,其完成時態可與表示"段時間"的狀語連用。表示"段時間"的短語有:for two years, during the past three years, since last year, how long等。如:I have learned English since I came here.自從我來到這兒就學英語了。

2.延續性動詞不能與表示短暫時間的"點時間"狀語連用。如:It raind at eight yesterday morning.(誤) rain為延續性動詞,而at eight表示"點時間",前後顯然矛盾。如果用延續性動詞表示壹瞬間的動作,可以借助come, begin, get等終止性動詞來表示。上句可改為:It began to rain at eight yesterday morning.(正)又如:

-When did you get to know Jack?

-Two years ago.

-Then you've known each other for more than two years.

-That's right.

三、終止性動詞的用法特征

1.終止性動詞可用來表示某壹動作完成,因此可用於現在完成時。如:

The train has arrived.火車到了。

Have you joined the computer group?妳加入電腦小組了嗎?

2.終止性動詞表示的動作極其短暫,不能持續。因此,不可與表示壹段時間的狀語連用(只限肯定式)。如:

(1)他死了三年了。

誤:He has died for three years.

正:He has been dead for three years.

正:He died three years ago.

正:It is three years since he died.

正:Three years has passed since he died.

(2)他來這兒五天了。

誤:He has come here for five days.

正:He has been here for five days.

正:He came here five days ago.

正:It is five days since he came here.

正:Five days has passed since he came here.

(1)、(2)句中的die、come為終止性動詞,不能與表示"段時間"的狀語連用。那麽,應如何正確表達呢?可以采用下面的四種方法:

(1)將句中終止性動詞轉換為相應的延續性動詞,如上面兩例中的第壹種正確表達方式。下面列舉幾例:leave→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold。

(2)將句中表示"段時間"的狀語改為表示過去確定時間的狀語,如下面兩例中的第二種正確表達方式。

(3)用句型"It is+段時間+since..."表達原意,如上面兩例中的第三種正確表達方式。

(4)用句型"時間+has passed+since..."表達原意,如上面兩例中的第四種正確表達方式。

3.終止性動詞可用於現在完成時否定式中,成為可以延續的狀態,因而可與表示壹段時間的狀語連用。如:

He hasn't left here since 1986.

I haven't heard from my father for two weeks.

4.終止性動詞的否定式與until/till連用,構成"not+終止性動詞+until/till ..."的句型,意為"直到……才……"。如:

You can't leave here until I arrive.直到我到了,妳才能離開這裏。

I will not go to bed until I finish drawing the picture tonight.今天晚上直到我畫完畫,我才上床睡覺。

5.終止性動詞可以用於when引導的時間狀語從句中,但不可以用於while引導的時間狀語從句中。when表示的時間是"點時間"(從句謂語動詞用終止性動詞),也可以是"段時間"(從句謂語動詞用延續性動詞)。而while表示的是壹個較長的時間或過程,從句謂語動詞用延續性動詞。如:

When we reached London, it was twelve o'clock. (reach為終止性動詞)

Please look after my daughter while/when we are away. (be away為延續性動詞短語)

6.終止性動詞完成時不可與how long連用(只限於肯定式)。如:

誤:How long have you come here?

正:How long have you been here?

正:When did you come here?

終止性動詞不用於進行時態,若是進行時態形式應譯成將來時態的意思。

終止性動詞和延續性動詞辨析 王嵩

英語動詞可以分為延續性動詞和終止性動詞。這兩種動詞在每年中考英語試題中出現率較高,筆者將其歸納分類,供同學們學習時參考。壹、延續性動詞 延續性動詞表示的動作不但可以延續,而且可以產生持久的影響。常見的這類動詞有:be,have,keep,know,learn,lie,live,read,sing,sleep,stand,stay,wait,walk,watch等。延續性動詞的用法很廣,但常見於現在完成時中的句子中,且常與for,how,long,since等引導的表示壹段時間的狀語或狀語從句連用。例如:1.I have learned more than 1,000 Chinese words since I came to China.自從來到中國,我已經學會了l,000多個漢字。2.We have lived in Linqing since we came here.自從來到這兒,我們就壹直住在臨清。3.I have kept the picture for about three years.這張畫我保存了大約三年。 二、終止性動詞 終止性動詞又稱為瞬間動詞或非延續性動詞,它表示的動作不能延續,也就是說動作壹旦發生就立即結束,並產生某種結果。常見的這類動詞有:accept,arrive,become,begin,borrow,break,buy,catch,close,come,die,end,fall,finish,get,give,go,join,leave,put,reach,receive,shut,start,stop等。終止性動詞用在現在完成時要註意下面三點: (壹)終止性動詞可直接用來表示某壹動作的完成。例如:1.They have reached Shanghai.他們已經到達了上海。2.Has he gone to London? 他已經到倫敦去了嗎? (二)終止性動詞表示的動作極其短暫,不能持續,所以,在現在完成時中壹般不能和以since,for等引導的表示壹段時間的狀語連用。例如:1.那老人已經死了壹周了。The old man has died for a week.(誤)2.他三天前就已經來這兒了。He has come here since three days ago.(誤)在以上兩句中,die和come都是終止性動詞,可用於現在完成時,但不能與以since或for引導的表示壹段時間的狀語連用。那麽,上面兩個句子應該怎樣譯成英語呢?請看下面四種譯法:1.把終止性動詞改為延續性的動詞。例如:①The old man has been dead for a week.②He has been here since three days ago.2.把原句中的壹段時間改為表示“過去”的時間,時態由現在完成時改變成壹般過去時。例如:①The old man died a week ago.②He came here three days ago.3.用“It is+時間+since…”句式。例如:①It is/has been a week since the old man died.②It has been/is three days since he came here.4.用“多長時間+has passed+since…”句式。例如:①A week has passed since the old men died.②Three days had passed since he came here. (三)有關特殊終止性動詞的用法。1.在while(表示壹段時間)引導的從句裏,謂語動詞不能使用終止性動詞,但可以把while改成when,這樣,從句裏的謂語動詞就可以使用終止性動詞了。因為when既可以表示時間的“點”,又可以表示時間的“段”。例如:While he got to America.he found his English Was very poor.(誤)When he got t0 America.he found his English was very poor.(正)2.終止性動詞的否定式與until連用時,意為“直到……才/不到什麽時間不……”等。例如:Don’t get off until the bus stops.車未停穩,切勿下車。3.終止性動詞不可以與how long引導的句式連用。例如:How long have you borrowed the magazine?(誤)When did you borrow the magazine?(正)How long have you kept the magazine?(正)
