1、 Unit 12 Life is full of the unexpected. 【學(xué)習(xí)目標(biāo)】 1. Past perfect Tense 過去完成時(shí) 構(gòu)成：had＋過去分詞 2. 過去完成時(shí)可以表示過去某一時(shí)刻或某一動(dòng)作之前完成的動(dòng)作或呈現(xiàn) 的狀態(tài)。也就是說發(fā)生在“過去的過去”。 【自主梳理】 bell, ring, go off, rush, run off, on time, give sb． a ride, lock, break down By the time I got there, the bus had already left． By

2、 the time I woke up, my father had already gone into the bathroom 【重點(diǎn)領(lǐng)悟】 過去完成時(shí)可以表示過去某一時(shí)刻或某一動(dòng)作之前完成的動(dòng)作或呈現(xiàn)的狀態(tài)。也就是說發(fā)生在“過去的過去”。 【探究提升】 基本用法 （1）表示在過去某一時(shí)刻或動(dòng)作以前完成了的動(dòng)作，也可以說過去的時(shí)間關(guān)于過去的動(dòng)作。即“過去的過去”?？梢杂胋y, before等介詞短語或一個(gè)時(shí)間狀語從句來表示，也可以用一個(gè)表示過去的動(dòng)作來表示，還可能通過上下文來表示。 例如： By nine o’clock last night, we had gotten 200

3、 pictures from the spaceship. 到昨晚9點(diǎn)鐘，我們已經(jīng)收到200 張飛船發(fā)來的圖片。 （2）表示由過去的某一時(shí)刻開始，一直延續(xù)到過去另一時(shí)間的動(dòng)作或狀態(tài)，常和for, since構(gòu)成的時(shí)間狀語連用。 例如： I had been at the bus stop for 20 minutes when a bus finally came. 當(dāng)車來的時(shí)候，我在車站已等了20分鐘。 He said he had worked in that factory since 1949. 他說自從1949年以來他就在那家工廠工作。 （3）敘述過去發(fā)生的事情，在已敘述了過去發(fā)生的

4、事情后，反過來追述或補(bǔ)述以前發(fā)生的動(dòng)作時(shí)，常使用過去完成時(shí)。 例如： Mr. Smith died yesterday. He had been a good friend of mine. 史密斯先生昨天去世了。他以前是我的好友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我對動(dòng)詞一無所知，因?yàn)槲覜]有好好學(xué)習(xí)功課。 （4）在含有定語從句的主從復(fù)合句中，如果敘述的是過去的事，先發(fā)生的動(dòng)作常用過去完成時(shí)。 例如： I returned the book that I had borrowed.

5、我已歸還了我借的書。 She found the key that she had lost. 她丟失的鑰匙找到了。 （5）過去完成時(shí)常常用在told,said,knew,heard,thought等動(dòng)詞后的賓語從句（或間接引語）中，這時(shí)從句中的動(dòng)作發(fā)生在主句表示的過去的動(dòng)作之前。 例如： He said that he had known her well. 他說他很熟悉她。 I thought I had sent the letter a week before. 我認(rèn)為我一星期前就把信寄出去了。 （6） 狀語從句：在過去不同時(shí)間發(fā)生的兩個(gè)動(dòng)作中，發(fā)生在前，用過去完成時(shí)；發(fā)生在后，用一般

6、過去時(shí)。 如when,before,after,as soon as,till/until引導(dǎo)的 例如： When I woke up, it had already stopped raining. 我醒來時(shí)雨已停了。 She didn’t go to bed until she had finished her work. 她直到把工作做完之后才睡覺。 注意：如果兩個(gè)動(dòng)作緊接著發(fā)生，則常常不用過去完成時(shí)，特別是在包含before和after的復(fù)合句中，因?yàn)?這 時(shí)從句的動(dòng)作和主句的動(dòng)作發(fā)生的先后順序已經(jīng)非常明確，這時(shí)可以用一般過去時(shí)代替過去完成時(shí)。 例如： After he arrived

7、 in England, Marx worked hard to improve his English. 馬克思到達(dá)英格蘭之后，努力提高他的英語水平。 （7）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： They had wanted to help but could not get there in time. 他們本來打算去幫忙，但沒有及時(shí)趕到那里。 We had hoped to be able to come and see you . 我們本來希望能來看看你。 （8）過去完成時(shí)還
