Unit 3 Amazing people（3）導(dǎo)學(xué)案一、 概念過去完成時(shí)表示在過去某一時(shí)間或動(dòng)作之前已經(jīng)發(fā)生或完成了的動(dòng)作，即“過去的過去( past-in-the-past )”。-|-|-|-那時(shí)以前 那時(shí) 現(xiàn)在 二、 構(gòu)成過去完成時(shí)由“助動(dòng)詞had + 過去分詞”構(gòu)成，其中 had 通用于各種人稱。 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. 過去完成時(shí)表示一個(gè)動(dòng)作或狀態(tài)在過去某一時(shí)間或動(dòng)作之前已經(jīng)完成或結(jié)束，即發(fā)生在“過去的過去”。例如： When I woke up, it had stopped raining. He had left when I arrived. 當(dāng)我到達(dá)時(shí)他已經(jīng)離開。2. 過去完成時(shí)是一個(gè)相對(duì)的時(shí)態(tài)，表示的是“過去的過去”，只有和過去某一時(shí)間或某一動(dòng)作相比較時(shí)才使用它。例如： She told me that she had written a new novel. I found the watch which I had lost. 我找到了我丟失的表。3. 過去完成時(shí)需要與一個(gè)表示過去的時(shí)間狀語連用，它不能離開過去時(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)的短語或從句連用。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. 過去完成時(shí)表示某一動(dòng)作或狀態(tài)在過去某時(shí)之前已經(jīng)開始，一直延續(xù)到這一過去時(shí)間，而且動(dòng)作尚未結(jié)束，仍然有繼續(xù)下去的可能。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點(diǎn)鐘時(shí)他就已經(jīng)工作了11小時(shí)。5. 動(dòng)詞think， want， hope， mean， plan， intend等用過去完成時(shí)來表示過去未曾實(shí)現(xiàn)的想法，希望，打算或意圖等。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. 過去完成時(shí)還可用在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、現(xiàn)在完成時(shí)與過去完成時(shí)的區(qū)別現(xiàn)在完成時(shí)著眼于現(xiàn)在，強(qiáng)調(diào)過去發(fā)生的某動(dòng)作對(duì)現(xiàn)在造成的影響和結(jié)果，或是由過去持續(xù)到現(xiàn)在的動(dòng)作。 例如：I have cleaned the classroom.我打掃干凈教室了。(強(qiáng)調(diào)掃地所產(chǎn)生的結(jié)果：地干凈了！) They have lived here for twenty years.他們住在這二十年了。(“住”從過去持續(xù)到現(xiàn)在的動(dòng)作用現(xiàn)在完成時(shí)) We have lived in Beijing since we came China.自我們來中國就住在北京了。(“住”是從過去持續(xù)到現(xiàn)在的動(dòng)作用現(xiàn)在完成時(shí)) 過去完成時(shí)則主要體現(xiàn)過去發(fā)生的兩動(dòng)作的先后有別，表達(dá)的是“過去的過去”，即比過去發(fā)生的某動(dòng)作都還要“過去”，兩動(dòng)作中先發(fā)生的就用過去完成時(shí)，后發(fā)生的則只用一般過去時(shí)。運(yùn)用過去完成時(shí)的句子往往有兩過去的時(shí)間或動(dòng)作。例如：Mr. Smith had lived in London for ten years before he came to China.史密斯先生在來中國之前就已經(jīng)在倫敦住過十年了。(“來”中國已成過去，而先前“住”在紐約就是過去的過去！)We had learned 2000 words by the end of last term. 在上期期末，我們就已經(jīng)學(xué)了2000個(gè)單詞。(“上期期末”已過去，而在其前“學(xué)”的就更過去了！)過去完成時(shí)專項(xiàng)練習(xí)一、單項(xiàng)填空1.
