時(shí)態(tài)連同語(yǔ)氣、語(yǔ)態(tài)、體貌和人稱為動(dòng)詞形式至少可能能夠表現(xiàn)出的5種語(yǔ)法特性。

有些語(yǔ)言,沒(méi)有時(shí)態(tài)的使用,如分析語(yǔ)的中文,但必要時(shí),仍有時(shí)間副詞的輔助。也有些語(yǔ)言,如日文,形容詞的詞形變化能表達(dá)出時(shí)間上的資訊,有著類似動(dòng)詞的時(shí)態(tài)性質(zhì)。還有些語(yǔ)言,如俄文,一個(gè)單詞就能表現(xiàn)出時(shí)態(tài)和體貌。

英語(yǔ)中的幾種時(shí)態(tài)在一定情況下可以互相轉(zhuǎn)換,以下是幾種常見(jiàn)的轉(zhuǎn)換形式:

一般過(guò)去時(shí)與現(xiàn)在完成時(shí)的轉(zhuǎn)換  在現(xiàn)在完成時(shí)中,延續(xù)性動(dòng)詞能與表示一段時(shí)間的狀語(yǔ)連用,瞬間動(dòng)詞卻不能。但是,可用別的表達(dá)方式:

①瞬間動(dòng)詞用于“一段時(shí)間 + ago”的一般過(guò)去時(shí)的句型中;

②瞬間動(dòng)詞可改成與之相對(duì)應(yīng)的延續(xù)性動(dòng)詞及短語(yǔ),與一段時(shí)間連用;

③瞬間動(dòng)詞用于“It is + 一段時(shí)間 + since + 一般過(guò)去時(shí)”的句型,請(qǐng)看:A. He joined the League two years ago. B. He has been in the League for two years. C. It is two years since he joined the League. D. Two years has passed since he joined the League.

一般現(xiàn)在時(shí)與現(xiàn)在進(jìn)行時(shí)的轉(zhuǎn)換在一般現(xiàn)在時(shí)中,at加上名詞表示“處于某種狀態(tài)”,如at work(在工作),at school(上學(xué)、上課)等。此短語(yǔ)可與進(jìn)行時(shí)態(tài)轉(zhuǎn)換。請(qǐng)看:Peter is at work,but Mike is at playPeter is working,but Mike is playing.

現(xiàn)在進(jìn)行時(shí)與一般將來(lái)時(shí)的轉(zhuǎn)換在現(xiàn)在進(jìn)行時(shí)態(tài)中g(shù)o,come,leave,start,arrive等動(dòng)詞常與表示將來(lái)的時(shí)間狀語(yǔ)連用表示將要發(fā)生的動(dòng)作。如:I am coming,Mum! 意為“我就來(lái),媽媽!”請(qǐng)看:The train is leaving soon. The train will leave soon.

4.完成進(jìn)行時(shí)

(現(xiàn)在、過(guò)去、將來(lái))完成進(jìn)行時(shí)是(現(xiàn)在、過(guò)去、將來(lái))完成時(shí)的強(qiáng)調(diào)形式,將放在完成時(shí)態(tài)部分講述。

三、完成時(shí)態(tài)

完成時(shí)態(tài)通常表示已完成或從事的動(dòng)作。它可分為:

1.現(xiàn)在完成時(shí)

(1)現(xiàn)在完成時(shí)用來(lái)表示對(duì)目前狀況仍有影響的,剛剛完成的動(dòng)作(常與yet,already,just連用),或者過(guò)去某一時(shí)刻發(fā)生的,持續(xù)到現(xiàn)在的情況(常與for,since連用)。例如:

1)I have just finished my homework.

2)Mary has been ill for three days.

(2)常與現(xiàn)在完成時(shí)連用的時(shí)間狀語(yǔ)有:since, for, during, over等引導(dǎo)出的短語(yǔ);副詞already, yet, just, ever, now, before, often, lately, recently等;狀語(yǔ)詞組this week (morning, month, year), so far, up to now, many times, up to the present等。例如:

1)I haven’t been there for five years.

2)So far, she hasn’t enjoyed the summer vacation.

3)There have been a lot of changes since 1978.

(3)完成時(shí)態(tài)可用在下列結(jié)構(gòu)中:

This (That, It) is (was) the first (second…) time +定語(yǔ)從句;This (That, It) is (was) the only (last) + n +定語(yǔ)從句;This (That, It) is (was) +形容詞最高級(jí)+ n +定語(yǔ)從句。如果主句的謂語(yǔ)動(dòng)詞是一般現(xiàn)在時(shí),從句的謂語(yǔ)動(dòng)詞通常用現(xiàn)在完成時(shí);如果主句謂語(yǔ)動(dòng)詞是一般過(guò)去時(shí),從句謂語(yǔ)動(dòng)詞通常用過(guò)去完成時(shí)。例如:

(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(guò)去完成時(shí)

(1)表示過(guò)去某時(shí)間前已經(jīng)發(fā)生的動(dòng)作或情況,這個(gè)過(guò)去的時(shí)間可以用by,before等介詞短語(yǔ)或一個(gè)時(shí)間狀語(yǔ)從句來(lái)表示;或者表示一個(gè)動(dòng)作在另一個(gè)過(guò)去動(dòng)作之前已經(jīng)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(dòng)詞expect, hope, mean, intend, plan, suppose, wish, want, desire等用過(guò)去完成時(shí),表示過(guò)去的希望、預(yù)期、意圖或愿望等沒(méi)有實(shí)現(xiàn)。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(guò)去想做而未做的事”的表達(dá)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(guò)去完成時(shí)常用于以下固定句型:

1)hardly, scarcely, barely + 過(guò)去完成時(shí)+ when + 過(guò)去時(shí)。例如:

Hardly had I got on the bus when it started to move.

2)no sooner +過(guò)去完成時(shí)+ than +過(guò)去時(shí)。例如:

No sooner had I gone out than he came to see me.

3)by (the end of ) +過(guò)去時(shí)間,主句中謂語(yǔ)動(dòng)詞用過(guò)去完成時(shí)。例如:

The experiment had been finished by 4 o’clock yesterday afternoon.

3.將來(lái)完成時(shí)

將來(lái)完成時(shí)表示在將來(lái)某一時(shí)刻將完成或在另一個(gè)未來(lái)的動(dòng)作發(fā)生之前已經(jīng)完成的動(dòng)作;也可以用來(lái)表示一種猜測(cè)。常與將來(lái)完成時(shí)連用的時(shí)間狀語(yǔ)有:by (the time / the end of ) +表示將來(lái)時(shí)間的短語(yǔ)和句子;before (the end of ) +表示將來(lái)時(shí)間的詞語(yǔ)或句子;when, after等加上表示將來(lái)動(dòng)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(jìn)行時(shí)

完成進(jìn)行時(shí)是完成時(shí)的強(qiáng)調(diào)形式,有現(xiàn)在完成進(jìn)行時(shí),過(guò)去完成進(jìn)行時(shí),將來(lái)完成進(jìn)行時(shí)。

(1)現(xiàn)在完成進(jìn)行時(shí)表示過(guò)去某一時(shí)刻之前開(kāi)始的動(dòng)作或狀態(tài)一直延續(xù)到過(guò)去某一時(shí)刻。例如:

I have been looking for my lost book for three days, but I still haven’t found it.

(2)過(guò)去完成進(jìn)行時(shí)表示過(guò)去某一時(shí)刻之前開(kāi)始的動(dòng)作或狀態(tài)一直延續(xù)到過(guò)去某一時(shí)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(lái)完成進(jìn)行時(shí)表示在將來(lái)某一時(shí)刻之前開(kāi)始的一個(gè)動(dòng)作或狀態(tài)一直延續(xù)到將來(lái)某一時(shí)刻。例如:

By the time you arrive tonight, she will have been typing for hours.

四:時(shí)態(tài)一致

時(shí)態(tài)一致是英語(yǔ)四、六級(jí)考試的一個(gè)重要內(nèi)容。通常應(yīng)由主句謂語(yǔ)的時(shí)態(tài)決定從句的謂語(yǔ)時(shí)態(tài)。一般原則是:

1、當(dāng)主句謂語(yǔ)使用現(xiàn)在時(shí)或?qū)?lái)時(shí),從句的謂語(yǔ)根據(jù)具體情況使用任何時(shí)態(tài)

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(dāng)主句謂語(yǔ)使用過(guò)去時(shí)的時(shí)候,從句的謂語(yǔ)必須使用過(guò)去范圍的時(shí)態(tài)

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(dāng)從句是表示沒(méi)有時(shí)間概念的真理時(shí),從句的謂語(yǔ)應(yīng)使用一般現(xiàn)在時(shí)。例如:

The teacher told them since light travels faster than sound, lightning appears to go before thunder.

注:在此種情況下,即使主句謂語(yǔ)用了過(guò)去式的各種時(shí)態(tài),從句謂語(yǔ)也應(yīng)用一般現(xiàn)在時(shí)。

4、從句謂語(yǔ)只能用虛擬語(yǔ)氣的情況

利用時(shí)態(tài)一致原則確定從句動(dòng)詞時(shí)態(tài)時(shí),還應(yīng)注意,若主語(yǔ)動(dòng)詞是表示命令、請(qǐng)求、要求、建議、勸告等的動(dòng)詞,從句謂語(yǔ)只能用虛擬語(yǔ)氣,不能遵循時(shí)態(tài)一致原則。例如:

We insisted that we do it ourselves.

動(dòng)詞的語(yǔ)態(tài)

語(yǔ)態(tài)也是動(dòng)詞的一種形式,英語(yǔ)有兩種語(yǔ)態(tài):主動(dòng)語(yǔ)態(tài)和被動(dòng)語(yǔ)態(tài)。主動(dòng)語(yǔ)態(tài)表示主語(yǔ)是動(dòng)作的執(zhí)行者,而被動(dòng)語(yǔ)態(tài)表示主語(yǔ)是動(dòng)作的承受者。

1)We use electricity to run machines. (主動(dòng)語(yǔ)態(tài))

2)Electricity is used to run machines. (被動(dòng)語(yǔ)態(tài))

1.不能用于被動(dòng)語(yǔ)態(tài)的動(dòng)詞和短語(yǔ)

(1)在英語(yǔ)中,不及物動(dòng)詞不能用于被動(dòng)語(yǔ)態(tài),但有些不及物動(dòng)詞(包括短語(yǔ))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(tài)或特征的及物動(dòng)詞,如:become, contain, cost, fit, have, resemble, suit也沒(méi)有被動(dòng)語(yǔ)態(tài)。

2.被動(dòng)語(yǔ)態(tài)的時(shí)態(tài)形式

常用的被動(dòng)語(yǔ)態(tài)有表1所列的幾種時(shí)態(tài)形式。

表1

時(shí)?SPAN lang=EN-US> 一般時(shí) 進(jìn)行時(shí) 完成時(shí)

現(xiàn)在 am asked am being asked

is asked is being asked

are asked are being asked

過(guò)去

was be asked was being asked

were be asked were being asked

將來(lái) shall be asked shall have been asked

will be asked will have been asked

過(guò)去 should be asked should have been asked

將來(lái) would be asked would have been asked

3.短語(yǔ)動(dòng)詞的被動(dòng)語(yǔ)態(tài)

短語(yǔ)動(dòng)詞轉(zhuǎn)換為被動(dòng)語(yǔ)態(tài)時(shí),通常被看作是一個(gè)動(dòng)詞,后面的介詞或副詞不能拆開(kāi)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(dòng)語(yǔ)態(tài)

“get + -ed分詞”結(jié)構(gòu)強(qiáng)調(diào)動(dòng)作的結(jié)果,而非動(dòng)作本身,常用來(lái)表示突發(fā)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”還可用于談?wù)摓樽约鹤龅氖拢侵鲃?dòng)的行為而不是被動(dòng)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(jié)婚)

5.能帶兩個(gè)賓語(yǔ)和復(fù)合賓語(yǔ)的動(dòng)詞改為被動(dòng)語(yǔ)態(tài)

(1)能帶兩個(gè)賓語(yǔ)的動(dòng)詞改為被動(dòng)語(yǔ)態(tài)時(shí),一次只能由一個(gè)賓語(yǔ)作主語(yǔ),另一個(gè)賓語(yǔ)被保留下來(lái)。例如:

1)We showed the visitors our new products.(主動(dòng)語(yǔ)態(tài))

2)The visitors were shown our new products.(被動(dòng)語(yǔ)態(tài))

3)Our new products were shown to the visitors.(被動(dòng)語(yǔ)態(tài))

(2)能帶復(fù)合賓語(yǔ)的動(dòng)詞改為被動(dòng)語(yǔ)態(tài)時(shí),原來(lái)的賓語(yǔ)補(bǔ)足語(yǔ)變?yōu)橹髡Z(yǔ)補(bǔ)足語(yǔ)。例如:

1)The teacher appointed him League secretary.(主動(dòng)語(yǔ)態(tài))

2)He was appointed League secretary.(被動(dòng)語(yǔ)態(tài))

6.被動(dòng)語(yǔ)態(tài)與系表結(jié)構(gòu)的區(qū)別

(1)The novel was well written.(系表結(jié)構(gòu))

(2)The novel was written by Diskens.(被動(dòng)語(yǔ)態(tài))

7.少數(shù)動(dòng)詞的主動(dòng)語(yǔ)態(tài)有時(shí)有被動(dòng)的意思

例1:The book is selling remarkably well.

例2:The song sounds very beautiful.

能這樣用的動(dòng)詞還有read(讀起來(lái)),clean(擦起來(lái)),wash(洗起來(lái)),write(寫起來(lái))。

例3:My watch needs cleaning. (= My watch needs to be cleaned).

能像need這樣用的動(dòng)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.

在英語(yǔ)中被動(dòng)語(yǔ)態(tài)分時(shí)態(tài),我給你舉些例子:
(1)一般現(xiàn)在時(shí):This song is often sung by children.孩子們常唱這首歌.
(2)一般過(guò)去時(shí):This house was built in 1958.這房子建于1958年.
(3)一般將來(lái)時(shí):Many buildings will be built in my home town.在我的家鄉(xiāng),許多大樓將要建成.
