(2) 否定句:主語(yǔ)＋had＋not＋動(dòng)詞的過(guò)去分詞＋其他. (3) 一般疑問(wèn)句:Had＋主語(yǔ)＋動(dòng)詞的過(guò)去分詞＋其他？ 肯定回答: Yes，主語(yǔ)＋had.否定回答:No，主語(yǔ)＋hadn't. (4) 特殊疑問(wèn)句:特殊疑問(wèn)詞或詞組＋一般疑問(wèn)句(即:had＋主語(yǔ)＋動(dòng)詞的過(guò)去分詞＋其他)? (5) 被動(dòng)語(yǔ)態(tài):主語(yǔ)＋had(not)＋been＋動(dòng)詞的過(guò)去分詞＋其他.,3. 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by/by the end of/before＋過(guò)去的時(shí)間點(diǎn)，by the time＋一般過(guò)去時(shí)從句等。如: I had finished reading the novel by nine o'clock last night.到昨天晚上九點(diǎn)鐘，我已經(jīng)讀完這部小說(shuō)。 We had learned over two thousand English words by the end of last term.到上學(xué)期末,我們已經(jīng)學(xué)完了超過(guò)兩千個(gè)英語(yǔ)單詞了. The bus had already left by the time/when I got there.我到達(dá)那里時(shí)，公共汽車已經(jīng)離開(kāi)了。,(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 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)從句要用過(guò)去完成時(shí)。如: She said that she had seen the film before.她說(shuō)她以前看過(guò)這部電影。,② 狀語(yǔ)從句中 在時(shí)間、條件、原因、方式等狀語(yǔ)從句中，主、從句的動(dòng)作發(fā)生有先后關(guān)系，動(dòng)作在前的，要用過(guò)去完成時(shí)，動(dòng)作在后的要用一般過(guò)去時(shí)。如: After he had finished his homework，he went to bed. 他完成作業(yè)后就上床睡覺(jué)了。 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，若主句、從句表示的動(dòng)作緊密相連，則主句、從句都用一般過(guò)去時(shí)。如: Where did you study before you came here？ 你來(lái)到這兒前在哪兒學(xué)習(xí)？ After he closed the door，he left the classroom. 他關(guān)上門后就離開(kāi)了教室。,(3) 根據(jù)上、下文來(lái)判定。 I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.我昨天在街上碰見(jiàn)王濤了。自從他去了北京，我們就沒(méi)見(jiàn)過(guò)面了。,4. 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。(“雨?！卑l(fā)生在“我醒來(lái)”之前) (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.他告訴我他寫了一本新書(shū)。(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: Peter had collected more than 300 Chinese stamps by the time he was ten.彼得到10歲的時(shí)候已經(jīng)收集了300多張中國(guó)郵票。 (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.到去年年底為止，他已經(jīng)在這個(gè)工廠工作了20年了。(已經(jīng)工作了 20 年，還有繼續(xù)進(jìn)行下去的可能),5. 過(guò)去完成時(shí)與一般過(guò)去時(shí)的區(qū)別 (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 already left when I arrived.我到達(dá)時(shí)他們已經(jīng)走了。(在我“到達(dá)”這一過(guò)去動(dòng)作之前，他們就已經(jīng)“離開(kāi)”了，因此用had left表示) I saw him in the street yesterday.昨天我在街上看見(jiàn)他了。(“看見(jiàn)他”這一動(dòng)作是在“昨天”這一過(guò)去的時(shí)間發(fā)生的),(2)在沒(méi)有明確的過(guò)去時(shí)間狀語(yǔ)作標(biāo)志時(shí)，謂語(yǔ)動(dòng)詞動(dòng)作發(fā)生的時(shí)間先后須依據(jù)上下文來(lái)判斷:先發(fā)生的用過(guò)去完成時(shí)，后發(fā)生的則用一般過(guò)去時(shí)。如: When I woke up，it had already stopped snowing.我醒來(lái)時(shí)雪已經(jīng)停了。 (3)當(dāng)兩個(gè)或兩個(gè)以上接連發(fā)生的動(dòng)作用 and 或 but 連接時(shí)，按時(shí)間順序，只需用一般過(guò)去時(shí)來(lái)代替過(guò)去完成時(shí)；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(shí)間的先后，因此也可以用過(guò)去時(shí)來(lái)代替過(guò)去完成時(shí)。如: I (had) heard the news before she told me.她告訴我那個(gè)消息之前我已經(jīng)聽(tīng)說(shuō)了。,6. 過(guò)去完成時(shí)與現(xiàn)在完成時(shí)的區(qū)別 過(guò)去完成時(shí)與already，ever，just，never，since＋時(shí)間點(diǎn)，for＋時(shí)間段等連用時(shí)，強(qiáng)調(diào)事件發(fā)生的先后順序，不涉及現(xiàn)在的情況。而現(xiàn)在完成時(shí)強(qiáng)調(diào)的是“過(guò)去的動(dòng)作或狀態(tài)對(duì)現(xiàn)在造成的影響”。如: She has worked in Chongqing for over two years.她已經(jīng)在重慶工作兩年多了。(現(xiàn)在仍在那兒工作) She had worked in Chongqing for over two years before she moved to Shanghai.她在搬到上海之前已經(jīng)在重慶工作兩年多了。(“搬到上?！笔沁^(guò)去，“在重慶工作”是發(fā)生在過(guò)去的過(guò)去),He has never seen such an interesting film before.他以前從未看過(guò)這么有趣的電影。(“看”盡管發(fā)生在過(guò)去，但涉及現(xiàn)在，即現(xiàn)在已經(jīng)知道或了解了這部電影) He said he had never seen such an interesting film before.他說(shuō)他以前從沒(méi)看過(guò)這么有趣的電影。(“他說(shuō)”發(fā)生在過(guò)去，“看過(guò)”是在“說(shuō)”之前，是過(guò)去的過(guò)去),語(yǔ)法精練 Ⅰ. 用括號(hào)內(nèi)所給單詞的適當(dāng)形式填空。 1.
