Unit 3 Amazing people（3）导学案一、 概念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，即“过去的过去( past-in-the-past )”。-|-|-|-那时以前 那时 现在 二、 构成过去完成时由“助动词had + 过去分词”构成，其中 had 通用于各种人称。 例如： They had already had breakfast before they arrived at the hotel. He didnt go to bed until he had finished he work.三、 用法1. 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，即发生在“过去的过去”。例如： When I woke up, it had stopped raining. He had left when I arrived. 当我到达时他已经离开。2. 过去完成时是一个相对的时态，表示的是“过去的过去”，只有和过去某一时间或某一动作相比较时才使用它。例如： She told me that she had written a new novel. I found the watch which I had lost. 我找到了我丢失的表。3. 过去完成时需要与一个表示过去的时间状语连用，它不能离开过去时间而独立存在。此时多与 already，yet，still，just，before，never 等时间副词及 by，before，until 等引导的短语或从句连用。例如： Before she came to China, Amy had taught English in a middle school for about five years. Tom had collected more than 300 Chinese stamps by the time he was seven. 4. 过去完成时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时间，而且动作尚未结束，仍然有继续下去的可能。例如： By the end of last year, my father had worked in the factory for twenty years. By six oclock he had worked eleven hours. 到6点钟时他就已经工作了11小时。5. 动词think， want， hope， mean， plan， intend等用过去完成时来表示过去未曾实现的想法，希望，打算或意图等。例如： I had wanted to help but could not get there in time.They had hoped to be able to come and see you.6. 过去完成时还可用在hardlywhen， no soonerthan， It was the first (second， etc) time (that)等固定句型中。例如： Hardly had he began to speak when the audience interrupted him.No sooner had he arrived than he went away again.It was the third time that she had been out of work that year.四、现在完成时与过去完成时的区别现在完成时着眼于现在，强调过去发生的某动作对现在造成的影响和结果，或是由过去持续到现在的动作。 例如：I have cleaned the classroom.我打扫干净教室了。(强调扫地所产生的结果：地干净了！) They have lived here for twenty years.他们住在这二十年了。(“住”从过去持续到现在的动作用现在完成时) We have lived in Beijing since we came China.自我们来中国就住在北京了。(“住”是从过去持续到现在的动作用现在完成时) 过去完成时则主要体现过去发生的两动作的先后有别，表达的是“过去的过去”，即比过去发生的某动作都还要“过去”，两动作中先发生的就用过去完成时，后发生的则只用一般过去时。运用过去完成时的句子往往有两过去的时间或动作。例如：Mr. Smith had lived in London for ten years before he came to China.史密斯先生在来中国之前就已经在伦敦住过十年了。(“来”中国已成过去，而先前“住”在纽约就是过去的过去！)We had learned 2000 words by the end of last term. 在上期期末，我们就已经学了2000个单词。(“上期期末”已过去，而在其前“学”的就更过去了！)过去完成时专项练习一、单项填空1.
