1) will / shall + 動(dòng)詞原形
多用于表達(dá)主觀愿望或必定會(huì)發(fā)生的事情(“將會(huì)如何”)

注意 瞬間動(dòng)詞通常是不能用現(xiàn)在完成時(shí)表持續(xù)性的,但其否定結(jié)構(gòu)則可以。如:

6. 現(xiàn)在完成時(shí)與一般過(guò)去時(shí)的區(qū)別
 
1) 現(xiàn)在完成時(shí)強(qiáng)調(diào)對(duì)現(xiàn)在的影響和結(jié)果,與現(xiàn)在有聯(lián)系;
而一般過(guò)去時(shí)強(qiáng)調(diào)這個(gè)動(dòng)作發(fā)生的時(shí)間是在過(guò)去,不涉及對(duì)現(xiàn)在的影響。如:

I have seen this film. (我已經(jīng)看過(guò)了這部電影)

I saw this film yesterday. (我是昨天看的這部電影)

 

2) 現(xiàn)在完成時(shí)常與模糊的時(shí)間狀語(yǔ)連用(如for, since, so far, ever, never, just, yet, till/until, up to now, always等),或者干脆沒(méi)有時(shí)間狀語(yǔ);
而一般過(guò)去時(shí)常與具體的時(shí)間狀語(yǔ)連用(如yesterday, last night, …ago, in 1980, in February等)。

 

3) 現(xiàn)在完成時(shí)表示持續(xù)時(shí)一般使用延續(xù)性動(dòng)詞(如live, teach, work, know等);
而一般過(guò)去時(shí)常使用瞬間動(dòng)詞(如begin, buy, die, marry等)。如:

He has lived in Hangzhou since last spring.

My grandfather bought the car five years ago.

 

7. 易錯(cuò)點(diǎn)辨析

 

1)  考生容易把一些瞬間動(dòng)詞用現(xiàn)在完成時(shí)表達(dá),這是錯(cuò)誤的。如:

(×) He has died for two years. 他死了兩年了。

(√) He has been dead for two years.

(√) He died two years ago.

(×) The film has begun for 10 minutes. 電影開(kāi)演十分鐘了。

(√) The film has been on for 10 minutes.

(√) The film began 10 minutes ago.

(×) She has married for three years. 她結(jié)婚有三年了。

(√) She has been married for three years.

(√) She married Mike three years ago.

 

2) 考生不懂如何區(qū)分have been to和have gone to,盡管兩者均可后接地點(diǎn),但have been to表示去過(guò)某地(現(xiàn)在已經(jīng)回來(lái)了),have gone to表示到某地去了(現(xiàn)在還沒(méi)回來(lái))。如:

She has been to Paris (three times).

She has gone to Paris.

 

7、過(guò)去完成時(shí)

 

標(biāo)志:had + 動(dòng)詞的過(guò)去分詞

 

1. 表示在過(guò)去的某個(gè)時(shí)間或動(dòng)作以前已經(jīng)發(fā)生的動(dòng)作或已經(jīng)存在的狀態(tài)。如:

By the end of last week he had finished the work.

He had left when I arrived.

 

2.  表示從過(guò)去某一時(shí)間開(kāi)始,一直延續(xù)到過(guò)去另一時(shí)間的動(dòng)作或狀態(tài)。如:

We had not seen each other since I left Beijing.

The film had been on for 5 minutes when I got to the cinema.

 

3. 某些表意向的動(dòng)詞(如intend, think, plan, expect, hope等)的過(guò)去完成時(shí)表示主語(yǔ)未曾實(shí)現(xiàn)的愿望、希望、打算。如:

I had intended to visit you last night, but someone called and I couldn’t get away.

We had hoped that you would come, but you didn’t.

 

4. (虛擬語(yǔ)氣)在條件狀體從句或wish / would rather等后面的從句中,使用過(guò)去完成時(shí)表示與過(guò)去事實(shí)相反的主觀愿望。如:

The party wouldn’t have been so perfect if you hadn’t come.

I wish I had gone with you to the concert that day.

 

5.  過(guò)去完成時(shí)與一般過(guò)去時(shí)
 
1) 基本區(qū)別:過(guò)去完成時(shí)表示以過(guò)去某時(shí)間為起點(diǎn)以前所發(fā)生的動(dòng)作或存在的狀態(tài),即過(guò)去完成時(shí)強(qiáng)調(diào)“過(guò)去的過(guò)去”,而一般過(guò)去時(shí)只表示以現(xiàn)在時(shí)間為起點(diǎn)以前所發(fā)生的事情或存在的狀態(tài)。如:

He studied there two years ago.他兩年前在那兒學(xué)習(xí)(離現(xiàn)在兩年)

He said he had studied there two years before.他說(shuō)他兩年前在那兒學(xué)習(xí)過(guò)。(離他說(shuō)話(huà)時(shí)兩年)

 

2) 特別注意:兩個(gè)動(dòng)作如果按順序發(fā)生,又不強(qiáng)調(diào)先后,或者用then, and, but等連詞連接時(shí),多用一般過(guò)去時(shí)。如:

When she saw the mouse, she screamed.

My aunt gave me a hat and I lost it.

 

8、過(guò)去將來(lái)時(shí)

 

標(biāo)志:would + 動(dòng)詞原形

 

1. 表示從過(guò)去某一時(shí)間來(lái)看將要發(fā)生的動(dòng)作或存在的狀態(tài),一般用于主句為過(guò)去時(shí)的賓語(yǔ)從句中。如:

He said he would come here next Friday.

I knew that he would help us when we were in trouble.

 

2. 表示過(guò)去的動(dòng)作習(xí)慣或傾向:

The old man would sit on a bench in the quite park for hours without doing anything.

When I worked on that farm, I would get up at 5 am.

 

3. 用于虛擬語(yǔ)氣中:

If I were you, I would not do that.

If he were here, he would show us how to do it.

 

4. 過(guò)去將來(lái)時(shí)的其他形式
1)  was / were going to + 動(dòng)詞原形。如:

He told us that he was going to attend the meeting.

She said that I was going to be sent to meet her at the railway station.

 

2) was / were to + 動(dòng)詞原形。如:

The building was to be completed next month.

3)  was / were about to + 動(dòng)詞原形。如:

We were about to leave there when it began to rain heavily and suddenly.

He was about to have lunch when the bell rang.
