英語動詞時態
A. 關於英語各種時態的動詞
英語共有16種時態,時態測試重點主要有:完成時態——現在完成時、過去完成時、將來完成時;進行時態——現在進行時、過去進行時、將來進行時、完成進行時;一般時態。
一、一般時態
1、一般現在時
(1)一般現在時表示沒有時限的持久存在的動作或狀態或現階段反復發生的動作或狀態,常和副詞usually,often,always sometimes, regularly,near,occasionally,every year, every week等連用。例如:
1)The moon moves round the earth..
2)Mr. Smith travels to work by bus every day.
(2)在由after,until,before,once,when,even if,in case,as long as,as soon as,the moment以及if,unless等引導的時間狀語從句或條件狀語從句中,通常用一般現在時代替將來時。例如:
1)I will tell him the news as soon as I see him.
2)I will not go to countryside if it rains tomorrow.
(3)某些表示起始的動詞,可用一般現在時表示按規定、計劃或安排要發生的動作,這類動詞有:be,go,come,start,depart,arrive,begin,leave等。例如:
1)The plane leaves at three sharp.
2)The new teachers arrive tomorrow.
(4)在由why,what,where,whoever,who,that,as等引導的從句中,也常用一般現在時代替將來時。例如:

2)幾種替代形式:
1)be going to +v在口語中廣泛使用,表示准備做或將發生的事情。例如:
I』m going to buy a house when we』ve saved enough money.
2)be to +v表示計劃安排要做的事,具有「必要」的強制性意義。例如:

(4)有些動詞不能用進行時,這是一類表示「感覺,感情,存在,從屬」等的動詞。如:see,hear,smell,taste,feel,notice,look,appear,(表示感覺的詞);hate,love,fear,like,want,wish,prefer,refuse,forgive(表示感情的動詞);be,exist,remain,stay,obtain(表示存在狀態的動詞);have,possess,own,contain,belong,consist of,form(表示佔有與從屬的動詞);understand,know,believe,think,doubt,forget,remember(表示思考理解的動詞)。但是如果它們詞義改變,便也可用進行時態。例如:
1)Tom looks pale. What』s wrong with him?
(look在此為聯系動詞,意為「顯得,看上去」)
2)Tom is looking for his books.
(look在此為實義動詞,意為「尋找」)
2.過去進行時
過去進行時表示一個過去的動作發生時或發生後,另一個過去的動作正在進行,或表示過去反復的習慣,常與always,continually,constantly等動詞連用。例如:

4.完成進行時
(現在、過去、將來)完成進行時是(現在、過去、將來)完成時的強調形式,將放在完成時態部分講述。
三、完成時態
完成時態通常表示已完成或從事的動作。它可分為:
1.現在完成時
(1)現在完成時用來表示對目前狀況仍有影響的,剛剛完成的動作(常與yet,already,just連用),或者過去某一時刻發生的,持續到現在的情況(常與for,since連用)。例如:
1)I have just finished my homework.

(1)This is one of the rarest questions that have ever been raised at such a meeting.
(2)There was a knock at the door. It was the second time someone had interrupted me that evening.
2.過去完成時
(1)表示過去某時間前已經發生的動作或情況,這個過去的時間可以用by,before等介詞短語或一個時間狀語從句來表示;或者表示一個動作在另一個過去動作之前已經完成。例如:
1)We had just had our breakfast when Tom came in.
2)By the end of last year they had turned out 5, 000 bicycles.
(2)動詞expect, hope, mean, intend, plan, suppose, wish, want, desire等用過去完成時,表示過去的希望、預期、意圖或願望等沒有實現。例如:
I had meant to take a good holiday this year, but I wasn』t able to get away.
另外兩種表示「過去想做而未做的事」的表達方式是:
1)was / were + to have done sth,例如:
We were to have come yesterday, but we couldn』t.
2)intended (expected, hope, meant, planned, supposed, wished, wanted, desired) + to have done sth,例如:
I meant to have told you about it, but I forgot to do so.
(3)過去完成時常用於以下固定句型:
1)hardly, scarcely, barely + 過去完成時+ when + 過去時。例如:
Hardly had I got on the bus when it started to move.
2)no sooner +過去完成時+ than +過去時。例如:
No sooner had I gone out than he came to see me.
3)by (the end of ) +過去時間,主句中謂語動詞用過去完成時。例如:
The experiment had been finished by 4 o』clock yesterday afternoon.
3.將來完成時
將來完成時表示在將來某一時刻將完成或在另一個未來的動作發生之前已經完成的動作;也可以用來表示一種猜測。常與將來完成時連用的時間狀語有:by (the time / the end of ) +表示將來時間的短語和句子;before (the end of ) +表示將來時間的詞語或句子;when, after等加上表示將來動作的句子等。例如:
1)By this time tomorrow you will have arrived in Shanghai.
2)I shall have finished this composition before 9 o』clock.
3)When we get on the railway station, the train will probably have left.
4.完成進行時
完成進行時是完成時的強調形式,有現在完成進行時,過去完成進行時,將來完成進行時。
(1)現在完成進行時表示過去某一時刻之前開始的動作或狀態一直延續到過去某一時刻。例如:
I have been looking for my lost book for three days, but I still haven』t found it.
(2)過去完成進行時表示過去某一時刻之前開始的動作或狀態一直延續到過去某一時刻。例如:
It had been raining cats and dogs for over a week and the downpour had caused landslides in many places.
(3)將來完成進行時表示在將來某一時刻之前開始的一個動作或狀態一直延續到將來某一時刻。例如:
By the time you arrive tonight, she will have been typing for hours.
四:時態一致
時態一致是英語四、六級考試的一個重要內容。通常應由主句謂語的時態決定從句的謂語時態。一般原則是:
1、當主句謂語使用現在時或將來時,從句的謂語根據具體情況使用任何時態
He says that he lives in Wuhan.
We hope that there will be many people at your party today.
「Did you hear that Bill finally sold the house?」 「Yes, but I don』t know who bought it.」
「There』s a lot of excitement on the street.」
「There certainly is. Do you suppose the astronauts have returned?」
2、當主句謂語使用過去時的時候,從句的謂語必須使用過去范圍的時態
He said he was writing a novel.
The teacher wanted to know when we would finish the experiment.
He said his father had been an engineer.
3、當從句是表示沒有時間概念的真理時,從句的謂語應使用一般現在時。例如:
The teacher told them since light travels faster than sound, lightning appears to go before thunder.
註:在此種情況下,即使主句謂語用了過去式的各種時態,從句謂語也應用一般現在時。
4、從句謂語只能用虛擬語氣的情況
利用時態一致原則確定從句動詞時態時,還應注意,若主語動詞是表示命令、請求、要求、建議、勸告等的動詞,從句謂語只能用虛擬語氣,不能遵循時態一致原則。例如:
We insisted that we do it ourselves.
動詞的語態
語態也是動詞的一種形式,英語有兩種語態:主動語態和被動語態。主動語態表示主語是動作的執行者,而被動語態表示主語是動作的承受者。
1)We use electricity to run machines. (主動語態)
2)Electricity is used to run machines. (被動語態)
1.不能用於被動語態的動詞和短語
(1)在英語中,不及物動詞不能用於被動語態,但有些不及物動詞(包括短語)容易引起誤用。如:appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。
(2)某些表示狀態或特徵的及物動詞,如:become, contain, cost, fit, have, resemble, suit也沒有被動語態。
2.被動語態的時態形式
常用的被動語態有表1所列的幾種時態形式。
表1
時?SPAN lang=EN-US> 一般時 進行時 完成時
現在 am asked am being asked
is asked is being asked
are asked are being asked
過去
was be asked was being asked
were be asked were being asked
將來 shall be asked shall have been asked
will be asked will have been asked
過去 should be asked should have been asked
將來 would be asked would have been asked
3.短語動詞的被動語態
短語動詞轉換為被動語態時,通常被看作是一個動詞,後面的介詞或副詞不能拆開或省略。例如:
1)So far no correct conclusion has arrived at.
2)All the rubbish should be got rid of.
4.「get + -ed分詞」的被動語態
「get + -ed分詞」結構強調動作的結果,而非動作本身,常用來表示突發性的,出乎意料的偶然事件。例如:
The boy got hurt on his way home from work.
另外,「get + -ed分詞」還可用於談論為自己做的事,是主動的行為而不是被動的行為。例如:
get dressed(穿衣服) get divorced(離婚)
get engaged(訂婚) get confused(迷惑不解)
get lost(迷路) get washed(洗臉)
get married(結婚)
5.能帶兩個賓語和復合賓語的動詞改為被動語態
(1)能帶兩個賓語的動詞改為被動語態時,一次只能由一個賓語作主語,另一個賓語被保留下來。例如:
1)We showed the visitors our new procts.(主動語態)
2)The visitors were shown our new procts.(被動語態)
3)Our new procts were shown to the visitors.(被動語態)
(2)能帶復合賓語的動詞改為被動語態時,原來的賓語補足語變為主語補足語。例如:
1)The teacher appointed him League secretary.(主動語態)
2)He was appointed League secretary.(被動語態)
6.被動語態與系表結構的區別
(1)The novel was well written.(系表結構)
(2)The novel was written by Diskens.(被動語態)
7.少數動詞的主動語態有時有被動的意思
例1:The book is selling remarkably well.
例2:The song sounds very beautiful.
能這樣用的動詞還有read(讀起來),clean(擦起來),wash(洗起來),write(寫起來)。
例3:My watch needs cleaning. (= My watch needs to be cleaned).
能像need這樣用的動詞還有:want, require, deserve, do, owe, bind等。
例4:The meat is cooking.
例5:The book written by the professor is printing.
B. 英語動詞的時態
英語動詞的時態
時態和時間是兩個不同的概念。時間是一種客觀存在的形式,它不依賴於任何一種特定的語言,為所有的文化共有。時態是一種語言的手段,依語言的不同而有所區別,它是屬於動詞的語法范疇。英語動詞時態是以動詞形式變化來表示句子中談到的動作、狀態的時間關系和說話的時間。因此我們可以看到時態和時間兩者間雖然有關系,但不可以混淆。
The plane leaves tomorrow morning. 飛機明晨起飛。
此句中的時態為一般現在時,但是它所表示的時間卻為將來(明晨)
英語動詞的常用時態總共有十六種:
一般現在時 現在進行時 一般過去時 過去進行時
一般將來時 將來進行時 現在完成時 過去完成時
將來完成時 現在完成進行時 過去完成進行時
1. 一般現在時
一般現在時的形式
是以動詞的原形表示的,當主語為第三人稱單數時,做謂語的動詞原形後要加上詞尾-s or –es, 其構成方式列表如下:
情況 構成 例詞
一般情況 詞尾加-s Reads, writes
以ch,sh,s,x,o結尾的詞 詞尾加-es Teaches,washes,guesses, fixes, goes
以輔音字母+Y 結尾的詞 變Y為I,再加-es Tries, carries
但是,動詞to be 和to have 的一般現在時的形式特殊如下:
一般動詞的詞形變化 To be 的詞形變化 To have 的詞形變化
I know it I am a student I have a pen.
You know it. You are a student You have a pen
He (she) knows it. He (she) is a student. He (she)has a pen.
We (you,they) know it. We (you,they) are students. We (you,they) have pens.
一般現在時的功用

Shakespears says, 「Neither a borrower or a lender be.」
莎士比亞說:「既不要向人借錢,也不要借錢給別人。」
一般過去時
一般過去時是表示在說話時間以前發生的動作或者狀態的動詞時態,它是英語時態體系中最重要的時態之一。
1) 一般過去時規則動詞的構成形式:
規則動詞在其原形後面加-ed:
to work-worked
以字母e結尾的規則動詞,只加-d:
to love---loved
對所有人稱均無詞形變化。
否定式均由did not + 動詞原形構成
I / you / he / she / they / we did not work.
疑問式均由 did + 主語 + 動詞原形 構成
拼寫注意:
情況 變化 例詞
動詞為單音節,以一個母音字母和一個輔音字母結尾 輔音字母雙寫,再加-ed Stop-stoppedAdmit—admitted
以y結尾的動詞,在y 前為輔音字母時 Y 變為 I ,加 – ed Carry –carriedHurry –hurried
以y 結尾的動詞,在y 前為母音字母時 加—ed Obey—obeyedEnjoy---enjoyed
在英語當中有一部分動詞的過去式變化形式是不規則的,這類動詞被稱為不規則動詞。總數大概不過200多個,但是使用頻率很高。主要分成三類:
1》 第一類不規則動詞的三種形式同形,如:
cost cost cost
cut cut cut
hurt hurt hurt
shut shut shut
set set set
注意,有些動詞的過去式與過去分詞有兩中形式,如:
bet bet / betted bet / betted
wed wed / wedded wed / wedded
wet wet / wetted wet / wetted
2》 第二類不規則動詞的過去式和過去分詞同形,如:
bend bent bent
bring brought brought
catch caught caught
hide hid hid / hidden

3》 第三類不規則動詞的原形、過去式和過去分詞都不相同,如:
原形 過去式 過去分詞

forbid forbade forbidden
grow grew grown
ring rang rung
wake woke / waked woken / waked
此外還有少數不規則動詞的過去分詞與原形相同,如:
come came come
become became become
run ran run
一般過去時的功用
1) 表示一個沒指明具體時間的過去的行動,如:
He worked in that bank for four years. (沒說明起始時間,但是現在不在那裡工作了)。

現在完成時的形式
現在完成時由to have 的現在時+過去分詞構成:
肯定式 否定式 疑問式 否定疑問式
I have worked I have not worked Have I worked? Have I not worked?
You have worked You havenot worked Have you worked? Have you not worked?
He (she)has worked. He(she)has not worked. Has he(she) worked? Has he(she) not worked?
We(you / they) have worked. We (you / they) have not worked. Have we (you / they) worked? Have we (you / they) not worked?
緊縮形式
現在完成時的功用
現在完成時可以說成是兼有現在與過去意義的一種復合時態。它與現在有密切聯系,如:
------Oh,dear, I』ve forgotten her name.
和現在的聯系就是 I don』t remember her name now.
------Fort has gone to Canada.
和現在的聯系就是 He is not here. He is in Canada now.
1) 表示延續到現在的動作 (有時是總計做了多少次等)。
How many times have you been to the United States?
She really loves that film. She has seen it eight times.
Tom has lived in Now York all his life.
2) 表示開始與過去而在說話時刻結束的行動,如:
I haven』t seen you for ages. 我好久沒見到你了。(說話時刻已經見到了)
This room hasn』t been cleaned for months. (也許從說話開始時刻就要打掃它了)
3) 表示過去的動作對現在造成的影響,如:

4) 和最高級連用,表示到現在為止是最……的
What a boring film! It』s the most boring film I』ve ever seen.
Is it a thick book?------Yes, it is the thickest book I』ve ever read.
5) 和句型 This is the first time…, It』s the first time 連用,如:

(相當於 he has never driven a car before.)
Is this the first time you』ve been in hospital?
Professor Johnson has lost his passport again. It』s the second time he has lost it.
6) 和ever, never, yet, just, already 等副詞連用,如:

We have never had a private car.
Has it stopped raining yet? (yet 表示期待雨停止)
Would you like something to eat?
No, thanks. I』ve just had lunch.
Don』t forget to mail the letter, will you?
I』ve already mailed it. (already 表示比預料的要快)
7)與since 連用,since 表示與某一時刻或從句連用,表示「從那一刻到說話時為止」,它總是與完成時連用,如:
She has been here since 6 o』clock.
He hasn』t been himself since the accident. (那次事故後,他從未完全康復)
Since I was a child I have lived in England.
一般過去時與現在完成時的比較
1) 過去時僅僅表示過去,現在完成時還表示與現在的關系,如:
He has lost his key.
He lost his key.
2) 與現在無關的或者過去很久的歷史事件不能用現在完成時

Tom lost his key yesterday.
詢問某事發生的具體時間或者地點時(when , what time, where), when , what time, where), 用一般過去時,如:
What time did they arrive?

比較:
Have you see Ann this moring? ( 說話時仍為上午)
Did you see Ann this morning? ( 說話時為下午)
Jack has lived in London for six years. 還在倫敦住
Jack lived in London for six years. 先不住倫敦了
I have never played golf in my life.
I didn』t play golf when I was on holiday last summer.
現在進行時
現在進行時是由助動詞to be 的現在時 + 現在分詞構成:
肯定式 否定式 疑問式
I am working.You are working.He (she) is working.We (you,they) are working. I am not working.You are not working.He (she) is not working.We (you,they) are not working. Am I working?Are you working?Is he (she) working?Are we (you,they) working?
現在分詞的構成,是在動詞原形上加—ing, 但是應該注意:
情況 變化 例詞
動詞以單個e 結尾 去掉e, 加 ing Love _lovingArgue _ arguing
動詞以 —ee結尾 直接加 ing Agree_ agreeingSee _ seeing
動詞為單音節:以單一母音字母 + 單一輔音字母結尾 輔音字母雙寫,再加 ing Hit _ hittingRun _runningStop _ stopping
動詞為雙音節或者多音節:最後一個音節為重讀音節,以單一母音字母 + 單一輔音字母結尾 輔音字母雙寫,再加 ing Be』gin be』ginningAd』mit ad』mitting
以 y 結尾的動詞 直接加 ing Carry carryingEnjoy enjoying
現在進行時的功用
1) 表示說話時正在發生或者進行的動作
Please don』t make so much noise, I』m studying.
Let』s get out. It isn』t raining any more.
2) 表示在現在相對較長一段時間內正在進行的動作,但是說話一刻不一定在做的動作
Have you heard about Tom? He is building his own house.
David is teaching English and learning Chinese in Beijing.
這些動作,在說話時並不一定在發生或進行,而是在包括說話的一剎那在內的一段時間內發生、進行的。
3)表示最近的確定的安排
Ann is coming tomorrow.
Oh, is she? What time is she arriving?
At 10:15.
Are you meeting her at the station?
I can』t. I』m working tomorrow morning.
以上句子也可以用be going to (do) 的形式來表示。但是談論已確定的安排時候,用現在進行時態顯得更加自然,除非受到動詞的功能的限制。在此,切不可用will, 如:
Alex is getting married next month. 不能用 will get married.
4) 和always 連用表示某種情緒,可能是厭煩也可能是贊揚,如:
Tom is always going away for weekends.
My husband is always doing homework.
有些動詞是表示一種狀態而不是動作,一般不用於進行時。例如,我們一般不說 I am knowing, 而說 I know. 常見的這類動詞有:
want like hate know see hear believe understand seem
think(相信) suppose remember need love realize mean forget prefer have (擁有)belong
To understand is to accept. 理解就是接受
Do you like Beijing?
Do you see the rainbow?
I remember him very well.
I think I understand what he wants.
一般現在時和現在進行時的比較
一般現在時表示的是一般、重復的動作或者事情
現在進行時表示說話時或說話前後正在發生的動作或事情,如:
Tom plays tennis every Sunday.
Where』s Tom? -------He is playing tennis.
What do you do? 你是干什麼工作的?
What are you doing here? 你在這里干什麼?
一般現在時是表示經久的情況,而現在進行時表示的是暫時的,如:
My parents live in Shanghai. They have been there for 50 years.
She』s living with some friends until she can find an apartment.
過去進行時
過去進行時的構成形式為:
I / he /she was
We / they / you were + 動詞的現在分詞
過去進行時的功用
1) 表示在過去某個時間後者某段時間正在進行的動作,如:
When I rang him up, he was having dinner.
This time last year I was living in Shanghai.
What were you doing at 10 o』clock last night?
2) 過去進行時和一般過去時連用,表示在一個動作發生的過程中,發生了另一個動作,如:
It was raining when I got up.
I fell asleep when I was watching television.
3) 過去一般時所說明的動作是已經完成的,而過去進行時不表示正在進行的動作一定會完成,如:
Tom was cooking the dinner.
Tom cooked the dinner.
現在完成進行時
其構成形式如下:
I / we / they have
He / she / it has been + 動詞的現在分詞
功用如下:
1) 表示一個在過去開始而在最近剛剛結束的行動,如:
Ann is very tired. She has been working hard.
Why are you clothes so dirty? What have you been doing?
2) 表示一個從過去開始但仍在進行的行動,如:
It has been raining for two hours. (現在還在下)
Jack hasn』t been feeling very well recently.
3) 表示一個從過去開始延續到現在,可以包括現在在內的一個階段內,重復發生的行動,如:
She has been playing tennis since she was eight.
4) 現在完成時強調動作行為的結果、影響,而現在完成進行時只強調動作行為本身,如:
Tom』s hands are very dirty. He has been repairing the car.
The car is going again now. Tom has repaired it.
C. 英語動詞時態
said 是過去時態 ,因此後面賓語從句中也用過去時態,因此may keep,like用其過去時態形式might keep, liked,
when後用come,代替將來時態will come,因為在帶狀語從句的句子中,主句從句都表示將來,從句則用一般式代替將來時態形式,am sleeping 表示正在睡覺,是進行時態
will表示將來可能性比較大, have taken 仍舊是現在時態代替將來時態,代替will have taken,表示將來已經服葯
D. 英語動詞時態是什麼
英語中不同時間和方式發生的動作或狀態要用謂語動詞的不同形式來表示,這種表示動作或狀態發生時間和方式的動詞形式稱作動詞時態。時間主要有四個主要部分,即現在、過去、將來和過去將來。動作方面也有四種,即一般、完成、進行和完成進行。把這些時間和動作方面結合在一起就構成16種動詞時態。(以play為例)具體表述如下:1、一般現在時(We
play);2、一般過去時(We
palyed);3、一般將來時(We
will

其實是英語動詞的時和體.時有現在,過去,將來和過去將來;體有一般,完成,進行和完成進行.而態有2種,即主動和被動.
E. 關於英語動詞時態
一、一般現在時:表示現在經常反復發生的動作、狀態、或習慣性的動作的狀態。 一般的形式由be動詞(am\is\are)或實義動詞引導。 如:I am a student.我是一個學生。(am在句中為be動詞) He swims in the pool.他在池裡游泳。(swims在句中為實義動詞)
二、現在進行時:表示現在正在進行的動作的時態。由be動詞(am\is\are)+現在分詞(動詞加ing形式)構成。 如:I am working.我正在工作。 She is studying.她正在學習。
三、一般過去時:表示過去經常或偶然發生的動作,或存在的狀態的時態。一般的形式和一般現在時差不多,由be動詞的過去時(was\were)或實義動詞的過去時引導。 如:I was a student.我以前是一個學生。(過去是學生) He swam(swim的過去時)in the pool. 他之前在池裡游泳。
四、一般將來時:表示將來發生的動作或存在的狀態的時態。 由will\shall + 動詞原形或be動詞原形構成。 如:I will be a student.我將成為一名學生。 He will swim in the pool.他將要到池裡去游泳。
五、現在完成時:表示在過去發生但與現在情況有聯系的動作或狀態的時態。 由 have\has + 過去分詞 構成。 如:I have talked.(talked 為talk的過去分詞)我已經講過話了。
