過去完成時語法精講

1、英語過去完成時語法精講一、過去完成時的概念與結(jié)構(gòu)特點 概念：過去完成時表示在過去某一時間或動作之前已經(jīng)發(fā)生或完成了的動作，即“過去的過去（ past-in-the-past ）”。-|- |-|->那時以前 那時 現(xiàn)在 構(gòu)成：過去完成時由“助動詞 had + 過去分詞”構(gòu)成，其中 had 通用于各種人稱。 They had already had breakfast before they arrived at the hotel. She had finished writing the composition by 10 ：00 this morning. 二、過去完成時的判斷依據(jù)

2、1. 由時間狀語來判定 一般說來，各種時態(tài)都有特定的時間狀語。與過去完成時連用的時間狀語有： （ 1 ） by + 過去的時間點。如： I had finished reading the novel by nine o'clock last night. （ 2 ） by the end of + 過去的時間點。如： We had learned over two thousand English words by the end of last term. （ 3 ） before + 過去的時間點。如： They had planted six hundred trees bef

3、ore last Wednesday. 2. 由“過去的過去”來判定。 過去完成時表示“過去的過去”，是指過去某一動作之前已經(jīng)發(fā)生或完成的動作，即動作有先后關(guān)系，動作在前的用過去完成時，在后的用一般過去時。這種用法常出現(xiàn)在： （ 1 ）賓語從句中 當(dāng)賓語從句的主句為一般過去時，且從句的動作先于主句的動作時，從句要用過去完成時。在told, said, knew, heard, thought等動詞后的賓語從句。如： She said that she had seen the film before. （ 2 ）狀語從句中 在時間、條件、原因、方式等狀語從句中，主、從句的動作發(fā)生有先后關(guān)系，動

4、作在前的，要用過去完成時，動作在后的要用一般過去時。如： When I got to the station, the train had already left. After he had finished his homework, he went to bed. 注意： before, after 引導(dǎo)的時間狀語從句中，由于 before 和 after 本身已表達(dá)了動作的先后關(guān)系，若主、從句表示的動作緊密相連，則主、從句都用一般過去時。如： Where did you study before you came here? After he closed the door, he l

5、eft the classroom. （3）表示意向的動詞，如hope, wish, expect, think, intend, mean, suppose等，用過去完成時表示"原本，未能" We had hoped that you would come, but you didn't.3. 根據(jù)上、下文來判定。 I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.三、過去完成時的主要用法 1. 過去完成時表示一個動作或狀態(tài)在

6、過去某一時間或動作之前已經(jīng)完成或結(jié)束，即發(fā)生在“過去的過去”。如： When I woke up, it had stopped raining. 我醒來時，雨已經(jīng)停了。（主句的動作發(fā)生在“過去的過去”） 2. 過去完成時是一個相對的時態(tài)，表示的是“過去的過去”，只有和過去某一時間或某一動作相比較時才使用它。如： He told me that he had written a new book. (had written 發(fā)生在 told 之前 ) 3. 過去完成時需要與一個表示過去的時間狀語連用，它不能離開過去時間而獨立存在。此時多與 already ， yet ， still ， jus

7、t ， before ， never 等時間副詞及 by ， before ， until 等引導(dǎo)的短語或從句連用。如： Before she came to China, Grace had taught English in a middle school for about five years. Peter had collected more than 300 Chinese stamps by the time he was ten. 4. 過去完成時表示某一動作或狀態(tài)在過去某時之前已經(jīng)開始，一直延續(xù)到這一過去時間，而且動作尚未結(jié)束，仍然有繼續(xù)下去的可能。如： By the end

8、 of last year, he had worked in the factory for twenty years. （ had worked 已有了 20 年，還有繼續(xù)進(jìn)行下去的可能）四、過去完成時與現(xiàn)在完成時的區(qū)別 現(xiàn)在完成時表示的動作發(fā)生在過去，但側(cè)重對現(xiàn)在產(chǎn)生的結(jié)果或造成的影響，與現(xiàn)在有關(guān)，其結(jié)構(gòu)為“助動詞 have (has) + 過去分詞”；過去完成時則是一個相對的時態(tài)，它所表示的動作不僅發(fā)生在過去，更強(qiáng)調(diào)“過去的過去”，只有和過去某時或某動作相比較時，才用到它。試比較： I have learned 1000 English words so far. 到目前為止我已經(jīng)學(xué)會

9、了 1000 個英語單詞。 I had learned 1000 English words till then.到那時為止我已經(jīng)學(xué)會了 1000 個英語單詞。 I'm sorry to keep you waiting. 對不起，讓你久等了。 Oh, not at all. I have been here only a few minutes. 沒什么，我只等了幾分鐘。（“等”的動作從過去某一時間點持續(xù)到現(xiàn)在） John returned home yesterday. 約翰昨天回到家的。 Where had he been? 他去哪兒了？（答語中使用過去完成時是指約翰在 retu

10、rned home 之前去了哪些地方，即“過去的過去”） 五、過去完成時與一般過去時的區(qū)別 雖然這兩種時態(tài)都表示過去發(fā)生的動作或存在的狀態(tài)，但在使用時應(yīng)注意以下幾點： 1. 時間狀語不同：過去完成時在時間上強(qiáng)調(diào)“過去的過去”；而一般過去時只強(qiáng)調(diào)過去某一特定的時間。試比較： They had arrived at the station by ten yesterday. They arrived at the station at ten yesterday. 2. 在沒有明確的過去時間狀語作標(biāo)志時，謂語動詞動作發(fā)生的時間先后須依據(jù)上下文來判斷：先發(fā)生的用過去完成時，后發(fā)生的則用一般過去時。如

11、： She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition. 3. 當(dāng)兩個或兩個以上接連發(fā)生的動作用 and 或 but 連接時，按時間順序，只需用一般過去時來代替過去完成時；另外，在 before ， after ， as soon as 引導(dǎo)的從句中，由于這些連詞本身已經(jīng)表示出時間的先后，因此也可以用過去時來代替過去完成時。如： He entered the room, turned on the li
