First, I had slept when the clock went off. Then by the time I ate breakfast, I had hurt my hand with a knife. Before I went to school, I had gone to the doctor. What about your morning? 时态分析: “去办公室”是发生在过去的事情,而“忘记吃早饭”发生在“去办公室”之前,所以第二个谓语动作发生在第一个谓语之前,是“过去的过去”,要用过去完成时。 I had forgotten to have breakfast before I going to the office this morning. 今天早晨去办公室之前,我忘记吃早饭了。 表示过去某一时间或动作以前已经发生或完成了的动作。它表示动作发生的时间是“过去的过去”。 表示发生在过去的动作对过去的某一点造成的某种影响或结果,用来指定在另一个过去行动之前就已经完成了的一个事件。 过去完成时 e.g. By nine o’clock last night, we had got 200 pictures from the spaceship. I had been at the bus stop for 20 minutes when a bus finally came. He said he had worked in that factory since 1949. The train had left before Tina reached the station. 过去完成时的构成: 过去完成时的谓语由“助动词had+过去分词”构成。否定式为“had not+过去分词”,had not缩写为hadn't。 过去完成时的用法: 1)表示—个动作或状态在过去某一时间或动作之前已经完成,发生在“过去的过去”。这个过去的时间可以用by,before等介词短语或者—个时间状语从句来表示。 e.g. When I woke up,it had stopped raining. 我醒来时,雨已经停了。 2) 表示某一动作或状态在过去某时之前已经开始,一直延续到这一过去的时间。常用表延续的时间状语如: by the end of+ 过去的时间点,by the time+从句等。 e.g. By the end of last year, she had worked in the factory for twenty years. 到去年年底,她已经在这家工厂工作20年了。 Grammar Focus When I got to school, I realized that I had left my backpack at home. By the time I got to school, the bell had rung. Before I got to the bus stop, the bus had already left. I was about to go up to my office when I decided to get a coffee first. As I was waiting in line with the other office workers, I heard a loud sound. 一、概念 过去完成时表示一个动作或状态在过去某一 时间或动作之前已经完成或结束,也可能是 早已完成或结束,即“过去的过去”;也可以 指过去的动作延续到过去的某个时刻。 二、结构 “had +动词的过去分词” 过去完成时 三、用法 表示过去某一时间或动作之前已经发生或完 成的动作或存在的状态。句中常用by, before, when, until等词引导时间状语。 它是以过去某一时间为起点,所以过去完成 时是一个相对的时态,表示的是“过
