過去完成時教案

1、授課學(xué)案學(xué)生姓名： 授課教師： 顏丹丹 班主任： 科目： 初三英語 上課時間： 2016 年 月 日 時 時跟蹤上次授課情況上次授課回顧 完全掌握 基本掌握 部分掌握 沒有掌握作業(yè)完成情況 全部完成 基本完成 部分完成 沒有完成本次授課內(nèi)容授課標題過去完成時學(xué)習(xí)目標1.通過與一般過去時的比較，導(dǎo)入過去完成時的概念。 2.使學(xué)生正確理解和掌握過去完成時的概念結(jié)構(gòu)和用法。重點難點過去完成時的用法。授課內(nèi)容【專題導(dǎo)入】原句：An apple a day, keeps the doctor away. ate an appleslept-|- |-|- Had eaten an apple slept

2、 now定從：I had eaten an apple before I slept. (After I had eaten an apple, I slept.)【考點梳理】一、過去完成時的概念與結(jié)構(gòu)特點 概念：過去完成時（past perfect tense）表示過去某一時間或動作以前已經(jīng)發(fā)生或完成了的動作。它表示動作發(fā)生的時間是“過去的過去”。它是一個相對的時態(tài)，只有在和過去某個時間或動作相比較時才會用到。-|- |-|-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，它的否定句是在had后邊加not，變一般疑問句是把had提前。其中 had 通用于各種人稱

3、。 E.g. I had reached the station before 9：00 oclock. I had not reached the station before 9：00 oclock. Had you reached the station before 9：00 oclock？（思考如何回答）二、用法：1、表示在過去某一時間或動作之前已經(jīng)發(fā)生或完成的動作。 這個過去的時間狀語有by, by the time of ,等介詞短語或者是when，before，after等引導(dǎo)的從句。如： 由by, by the end of, by then 等引導(dǎo)的狀語從句。 By the

4、 time they arrived, the bus had left. 翻譯：昨夜十點鐘之前他已經(jīng)上床睡覺了。 He had gone to bed by 10:00 last night. 由when，before，after等引導(dǎo)的從句。They had already finished cleaning the classroom when their teacher came.(當老師來的時候他們已經(jīng)打掃完了教師) 在told, said, knew, heard, thought等動詞引導(dǎo)的賓語從句中，一般用過去完成時。，表示在談話或產(chǎn)生某種想法之前發(fā)生的事情。 例如：He sa

5、id that he had known her well. 他說他很熟悉她。 She wondered who had left the door open. 她想知道是誰沒關(guān)門。I thought I had sent the letter a week before. 我認為我一星期前就把信寄出去了。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)。常與for 或since 等連用.如: She had worked in this school since it opened 25 years ago. I had been at the bus stop for 20

6、minutes when a bus finally came. 當車來的時候，我在車站已等了20分鐘。 三、過去完成時-語法判定根據(jù)“標志”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： by ， by the end of ，by then, 或者when，after， before 等引導(dǎo)的狀語從句。以及句子中會出現(xiàn)的already,just,once等詞語。也會有for或sinceI met Wang Tao in the street yesterday. We hadnt seen each other since he went to Be

7、ijing. 注意：我們不一定非得用過去完成時表示過去先發(fā)生的事件，因為有時句意非常清楚。before, after 引導(dǎo)的時間狀語從句中，由于 before 和 after 本身已表達了動作的先后關(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。例如： After he had finished his homework, he went to bed./After I finished my work, I went home. After he closed the door, he left the classroom.動作的順序往往十分清楚時，我們通常用一般過去時表示依次

8、發(fā)生的事件。例如：I got out of the taxi, paid the fare, tipped the driver and dashed into the station. 【經(jīng)典例題】1. He _ in Shanghai University for four years before he _ Beijing.A. studied, had gone B. had studied, wentC. has studied, goes D. had studied, had gone解析：他去北京之前在上大學(xué)學(xué)習(xí)了4年 。在上海學(xué)習(xí)的動作發(fā)生在去北京之前，因此第一個空應(yīng)用過去完

9、成時。此題選B。2.The students _ busily when Miss Brown went to get a book she _ in the office.A. had written, left B. were writing, has left C. had written, had left D. were writing, had left答案D。 “把書忘在辦公室”發(fā)生在“去取書”這一過去的動作之前，因此“忘了書”這一動作發(fā)生在過去的過去，用過去完成時。句中when代表時間的一點，表示在“同學(xué)們正忙于”這一背景下， when所引導(dǎo)的動作正在發(fā)生。因此前一句應(yīng)用過去進

10、行時。3. Xiao Pei said she _ Hainan for 3 months.A. has been in B. had been in C. had been to D. had gone to解析：小培說她去了海南三個月 。have been to 和have gone to 都是短暫性的動詞短語。所以適應(yīng)表示狀態(tài)的had been in. 應(yīng)選B.（教師版打印，學(xué)生版解析不打印） 【舉一反三】一、單選 1 When Li Ming hurried home， he found that his mother _already_to hospital.A has； been

11、sent B had； sent C has； sent D had； been sent 2 We _five English songs by the end of last term.A had learned B learned C have learned D will have learned 3 Han Mei told me she _lunch， so she was very hungry.A has had B hasnt have C have had D hadnt had 4 By the end of 1976， many buildings _built in

12、the city.A have been B have C had been D will 5 She _her keys in the office so she had to wait until her husband _home.A has left； comes B had left； would come C had left； came D left； had come 6 He said that it was at least ten years since I _a good drink.A had enjoyed B was enjoying C have enjoyed

13、 D have been enjoying 7 The meeting _when Mr. Wang _to school. A has begun；get B has been on；get C had begun；got D had been on；got （答案：1D 2 A 3 D 4 C 5 C 6 A 7 C） 【回顧與反思】做題時常見錯誤如下：一、had形式易寫錯例：例：He hads （have） gone home when I got to his office.答案：had解析：have/has 的過去式都為had， had 在過去完成時中也是助動詞，不能再有單三人稱的變

14、化。二、易與現(xiàn)在完成時弄混例：He asked what I have （have） said.答案：had解析：現(xiàn)在完成時強調(diào)對現(xiàn)在的影響或結(jié)果。而過去完成時強調(diào)對過去的影響或結(jié)果。三、易與一般過去時弄混例：She lived （live） in New York for eight years before he came to China.答案：had lived解析：一般過去時表示過去發(fā)生的動作或存在的狀態(tài)。 而過去完成時主要體現(xiàn)過去發(fā)生的兩動作先后有別，即比過去發(fā)生的某動作還要“過去”，兩動作中先發(fā)生的是過去完成時，后發(fā)生的則只用一般過去時。 課后作業(yè)學(xué)生姓名： 授課教師： 顏丹丹
