【正文】 position by 10 ： 00 this morning. 二、過(guò)去完成時(shí)的判斷依據(jù) 1. 由時(shí)間狀語(yǔ)來(lái)判定 一般說(shuō)來(lái)，各種時(shí)態(tài)都有特定的時(shí)間狀語(yǔ)。與過(guò)去完成時(shí)連用的時(shí)間狀語(yǔ)有： （ 1 ） by + 過(guò)去的時(shí)間點(diǎn)。 如： I had finished reading the novel by nine o39。clock last night. （ 2 ） by the end of + 過(guò)去的時(shí)間點(diǎn)。 如： We had learned over two thousand English words by the end of last term. （ 3 ） before +過(guò)去的時(shí)間點(diǎn)。 如： They had planted six hundred trees before last Wednesday 2. 由“過(guò)去的過(guò)去”來(lái)判定。 過(guò)去完成時(shí)表示“過(guò)去的過(guò)去”，是指過(guò)去某一動(dòng)作之前已經(jīng)發(fā)生或完成的動(dòng)作，即動(dòng)作有先后關(guān)系，動(dòng)作在前的用過(guò)去完成時(shí)，在后的用一般過(guò)去時(shí)。這種用法常出現(xiàn)在： 1）表示意向的動(dòng)詞，如 hope, wish, expect, think, intend, mean, suppose 等，用過(guò)去完成時(shí)表示 原本 ?，未能 ? We had hoped that you would e, but you didn39。t. 2 ）賓語(yǔ)從句中 當(dāng)賓語(yǔ)從句的主句為一般過(guò)去時(shí)，且從句的動(dòng)作先于主句的動(dòng)作時(shí)，從句要用過(guò)去完成時(shí)。在 told, said, knew, heard, thought等動(dòng)詞后的賓語(yǔ)從句。 said that she had seen the film before he had finished his homework, he went to bed. 注意： before, after 引導(dǎo)的時(shí)間狀語(yǔ)從句中，由于 before 和 after本身已表達(dá)了動(dòng)作的先后關(guān)系，若主、從句表示的動(dòng)作緊密相連，則主、從句都用一般過(guò)去時(shí)。如： did you study before you came here? he closed the door, he left the classroom. 3. 根據(jù)上、下文來(lái)判定。 I met Wang Tao in the street yesterday. We hadn39。t seen each other since he went to Beijing. 三、過(guò)去完成時(shí)的主要用法 1. 過(guò)去完成時(shí)表示一個(gè)動(dòng)作或狀態(tài)在過(guò)去某一時(shí)間或動(dòng)作之前已經(jīng)完成或結(jié)束，即發(fā)生在“過(guò)去的過(guò)去”。如： When I woke up, it had stopped raining. 我醒來(lái)時(shí)，雨已經(jīng)停了。（主句的動(dòng)作發(fā)生在“過(guò)去的過(guò)去”） 2. 過(guò)去完成時(shí)是一個(gè)相對(duì)的時(shí)態(tài)，表示的是“過(guò)去的過(guò)去”，只有和過(guò)去某一時(shí)間或某一動(dòng)作相比較時(shí)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(guò)去完成時(shí)需要與一個(gè)表示過(guò)去的時(shí)間狀語(yǔ)連用，它不能離開(kāi)過(guò)去時(shí)間而獨(dú)立存在。此時(shí)多與already， yet ， still ， just ， before ， never 等時(shí)間副詞及 by ， before ， until 等引導(dǎo)的短語(yǔ)或從句連用。如： Before she came to China, Grace had taught English in a middle school for about five years. 4. 過(guò)去完成時(shí)表示某一動(dòng)作或狀態(tài)在過(guò)去某時(shí)之前已經(jīng)開(kāi)始， 一直延續(xù)到這一過(guò)去時(shí)間，而且動(dòng)作尚未結(jié)束，仍然有繼續(xù)下去的可能。如： By the end 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） 5. 過(guò)去完成時(shí)也用于 hardly...when...（剛 ?就 ?） no sooner...than... （剛 ?就 ?） , It was the first time + that等一些固定句型中。 He had no sooner left the room than they began to talk about him. 他剛離開(kāi)房間，他們就議論起他來(lái)。 \We had hardly begun when we were told to stop. 我們剛開(kāi)始就被叫停。 It was the first time that he had ever spoken to me in such a tune. 他用這樣的語(yǔ)調(diào)跟我講話，這是第一次。 四、過(guò)去完成時(shí)與現(xiàn)在完成時(shí)的區(qū)別 現(xiàn)在完成時(shí)表示的動(dòng)作發(fā)生在過(guò)去，但側(cè)重對(duì)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(dòng)詞 have (has) + 過(guò)去分詞”；過(guò)去完成時(shí)則是一個(gè)相對(duì)的時(shí)態(tài)，它所表示的動(dòng)作不僅發(fā)生在過(guò)去，更強(qiáng)調(diào)“過(guò)去的過(guò)去”，只有和過(guò)去某時(shí)或某動(dòng)作相比較時(shí)，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(huì)了 1000 個(gè)英語(yǔ)單詞。 I had learned 1000 English words till then. 到那時(shí)為止我已經(jīng)學(xué)會(huì)了 1000 個(gè)英語(yǔ)單詞。 五、過(guò)去完成時(shí)與一般過(guò)去時(shí)的區(qū)別 雖然這兩種時(shí)態(tài)都表示過(guò)去發(fā)生的動(dòng)作或存在的狀態(tài)，但在使用時(shí)應(yīng)注意以下幾點(diǎn)： 1. 時(shí)間狀語(yǔ)不同：過(guò)去完成時(shí)在時(shí)間上強(qiáng)調(diào)“過(guò)去的過(guò)去”；而一般過(guò)去時(shí)只強(qiáng)調(diào)過(guò)去某一特定的時(shí)間。試比較： They had arrived at the station by ten yesterday. They arrived at the station at ten yesterday.
