Lead in Do you remember any unexpected situation in your daily life? brainstorm 导入 教学过程 2. I have a good friend ,her name is Mary , she has a bad day,Let’s look at her story. She got up late. She overslept. By the time she got up, someone had already gotten in the bathroom. She rushed out the door. The bus had left before she got to the station. When she got to school, she realized she had left her backpack at home. 3. 过去完成时的判断依据： (1) 由“过去的过去”来判定 知识讲解 过去完成时表示“过去的过去”，是指过去某一动作之前已经发生或完成的动作，即动（难点突破） 作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在：(2)A: 状语从句中 When I got to the station, the train had already left. 宾语从句中She said that she had seen the film before. (2) 由时间状语来判定 by + 过去的时间点。如：I had finished reading the novel by nine o'clock last night. by the end of + 过去的时间点。如：We had learned over two thousand English words by the end of last term. before + 过去的时间点。如They had planted six hundred trees before last Wednesday. (3) 根据上、下文来判定。 I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing. (4)过去完成时典型错误例析： 1.昨晚我们看了电影。 a. We had seen the film yesterday evening. b. We saw the film yesterday evening. 过去完成时所表示的时间是“过去的过去”，只有在和过去某时或某动作相比较时才用到它。如果时间只是一个单纯的过去时间，则句子只能用一般过去时，而不用过去完成时。 2．当我到达那儿时，电影已经放了五分钟了。 a. The film has been on for five minutes when I got there. b. The film had been on for five minutes when I got there. 在过去某一时间或动作之前发生或完成了的动作，要用过去完成时。它的动作的起点为过去，终点也为过去，即“过去的过去”。而现在完成时的动作起点为过去，终点则为现在 1.Millie ran back to school because she had left her magazine in the classroom. 课堂练习 （难点巩固） What happened first? A . Millie ran back to school. B. Millie left her magazine in the classroom. 2.Simon left school late because the football game had started late. What happened first? a.Simon left school late. b.The football game started late. 3.Daniel arrived out of breath --- he had gone to the wrong cinema. What happened first? a. Daniel arrived out of breath. b. Daniel went to the wrong cinema. 4.Amy had lost her purse and had to go to the police station. What happened first? a. Amy lost her purse. b. Amy went to the police station. What did we learn today? 过去完成时（The Past Perfect Tense） (1) 构成：由“助动词had(用于各种人称和数) + 过去分词”构成 ；否定式had not +过去分词 缩写形式：hadn’t 小结 (2) 用法：过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。 (3) 它所表示动作发生的时间是“过去的过去”。 ① 表示过去某一时间可用by, before 等构成的短语来表示。 ② 也可以用when, before 等引导的时间状语从句来表示。 ③ 还可以通过状语从句或通过上下文暗示。 本文来源：https://www.dywdw.cn/05d7dbe52d60ddccda38376baf1ffc4fff47e21c.html
