    Where there is a will, there is a way.

    4. 表示現在瞬間的動作:

    Here comes the bus!

    5. 表示將來

    1) 表按規(guī)定、計劃、安排將要發(fā)生的動作(僅限于某些表示“來、去、動、停、開始、結束、繼續(xù)”等的趨向動詞),可以與表示未來的時間狀語搭配使用。常見的用法是:飛機、火車、輪船、汽車等定期定點運行的交通狀況。如:

    The next train leaves at 3 o’clock this afternoon.

    How often does the shuttle bus run?

    2) 在時間和條件狀語從句中常使用一般現在時表示將來發(fā)生的事情:

    I shall go there tomorrow unless I’m too busy.

    2

    一般過去時

    標志:動詞過去式

    圖片

    *閉音節(jié):元音字母a, e, i, o, u如果發(fā)字母本來的音則稱為開音節(jié),否則稱為閉音節(jié)。

    1. 表示過去某時所發(fā)生的動作或存在的狀態(tài),常與表示過去的時間狀語連用(e.g. yesterday, this morning, just now, a moment ago, in May, last night / year / week, once upon a time, the other day, before …, when …, in the past等)。如:

    Jim rang you just now.

    Liu Ying was in America last year.

    2. 表示過去經?;蚍磸桶l(fā)生的動作,特別是used to do表達的句型,本身表示的就是過去常常。如:

    When I was a kid, I often played football in the street.

    She used to visit her mother once a week.

    *注意區(qū)分sb. used to do sth.(某人過去常常做某事,此處to是動詞不定式標志符號)和sb. be used to sth./doing sth.(某人習慣于某物/做某事,此處to是介詞)。

    3. 代替一般現在時,表示一種婉轉、客氣、禮貌、商量的語氣。此用法僅適用于少數動詞(如want, hope, wonder, think, intend等)及情態(tài)動詞could, would。如:

    I wondered if you could have a word with me.

    I hoped you could help me with my English.

    Would you mind my sitting here?

    4. 虛擬語氣中用一般過去時表示現在或將來時間的動作或狀態(tài)。常用句型有:

    *shall作助動詞時一般只用于第一人稱

    2) be going to + 動詞原形

    表示即將發(fā)生或打算要做的事:

    It is going to rain.

    5

    過去進行時

    標志:have / has + 動詞的過去分詞

    I have been busy since last week.

    注意 瞬間動詞通常是不能用現在完成時表持續(xù)性的,但其否定結構則可以。如:

    5. 與現在完成時連用的常見詞語

    能與現在完成時連用的詞語很多,just, already, yet, before, never, ever, recently等,但常見的有:

    1) since 自從

    I have been there many times since the war.

    We haven’t seen each other since last week.

    We have been friends ever since.

    2) in / for / during the past/last … years 在過去/最近…中

    I’ve been ill for the past three weeks.

    Great changes have take place in the last ten years.

    I have been here (for) the last/past month.

    3) so far 到目前為止

    I have heard nothing from him up till now.

    Up till now we have planted over 2000 trees.

    5) It is/will be the first/second … time that … 這是第一/二…次…

    It’s the first time (that) I’ve been here.

    It is the second time (that) I have met him today.

    6) This is + 形容詞最高級 + that … 這是最…

    This is the best film that I’ve (ever) seen.

    6. 現在完成時與一般過去時的區(qū)別

    1) 現在完成時強調對現在的影響和結果,與現在有聯系;

    而一般過去時強調這個動作發(fā)生的時間是在過去,不涉及對現在的影響。如:

    I have seen this film. (我已經看過了這部電影)

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

    2) 現在完成時常與模糊的時間狀語連用(如for, since, so far, ever, never, just, yet, till/until, up to now, always等),或者干脆沒有時間狀語;

    而一般過去時常與具體的時間狀語連用(如yesterday, last night, …ago, in 1980, in February等)。

    3) 現在完成時表示持續(xù)時一般使用延續(xù)性動詞(如live, teach, work, know等);

    而一般過去時常使用瞬間動詞(如begin, buy, die, marry等)。如:

    He has lived in Hangzhou since last spring.

    My grandfather bought the car five years ago.

    7. 易錯點辨析

    1) 考生容易把一些瞬間動詞用現在完成時表達,這是錯誤的。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,但have been to表示去過某地(現在已經回來了),have gone to表示到某地去了(現在還沒回來)。如:

    She has been to Paris (three times).

    She has gone to Paris.

    7

    過去完成時

    標志:had + 動詞的過去分詞

    1. 表示在過去的某個時間或動作以前已經發(fā)生的動作或已經存在的狀態(tài)。如:

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

    He had left when I arrived.

    2. 表示從過去某一時間開始,一直延續(xù)到過去另一時間的動作或狀態(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. 某些表意向的動詞(如intend, think, plan, expect, hope等)的過去完成時表示主語未曾實現的愿望、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. (虛擬語氣)在條件狀體從句或wish / would rather等后面的從句中,使用過去完成時表示與過去事實相反的主觀愿望。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. 過去完成時與一般過去時

    1) 基本區(qū)別:過去完成時表示以過去某時間為起點以前所發(fā)生的動作或存在的狀態(tài),即過去完成時強調“過去的過去”,而一般過去時只表示以現在時間為起點以前所發(fā)生的事情或存在的狀態(tài)。如:

    He studied there two years ago.他兩年前在那兒學習(離現在兩年)

    He said he had studied there two years before.他說他兩年前在那兒學習過。(離他說話時兩年)

    2) 特別注意:兩個動作如果按順序發(fā)生,又不強調先后,或者用then, and, but等連詞連接時,多用一般過去時。如:

    When she saw the mouse, she screamed.

    My aunt gave me a hat and I lost it.

    8

    過去將來時

    標志:would + 動詞原形

    1. 表示從過去某一時間來看將要發(fā)生的動作或存在的狀態(tài),一般用于主句為過去時的賓語從句中。如:

    He said he would come here next Friday.

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

    2. 表示過去的動作習慣或傾向:

    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. 過去將來時的其他形式

    1) was / were going to + 動詞原形。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 + 動詞原形。如:

    The building was to be completed next month.

    Li Lei was to arrive soon.

    3) was / were about to + 動詞原形。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.
