33、en I got to the cinema, the film had been on for five minutes.当我到达电影院时，电影已演了五分钟了。(got是一个过去的“时间点”，电影“开始”在我“到达”之前，是“过去的过去”。因为for five minutes为延续一段的时间状语，应用可延续的系表结构be on的过去完成时形式。）【温馨提示】过去完成时是一个相对的时态，表示的是“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，因此当原句中若找不到一个“过去的时间”作为参照点时，是不能用过去完成时的。【例句】He got to the railway station a

34、nd suddenly realized that he had forgotten to bring his ticket.他到了火车站后忽然意识到他竟忘记带车票了。（“忘记”这一动作在“意识到”这一动作之前。）1.Why didnt you go to the movie yesterday?Because I _it before.

36、【课堂变式】2.

40、e story and fear spread across the whole country. Wells 讲述这个新闻起来如此的真实，以致成百上千的人都相信了这个故事，进而引发了全国性的恐慌。so that在此引导结果状语从句，so后面应加一个形容词或副词，意为“如此以至于”。This book is so interesting that everyone in our class wants to read itHe ran so fast that I couldn't catch up with him他跑得那么快，以至于我跟不上他。（so副词）【横向辐射】表示“如此以至

41、于”之意时， sothat, tooto do sth., enough to do sth. 这三个句型可互换使用。1.在sothat句型中，当主语和从句都是肯定式，且主、从句的主语指的是同一人时，可简化为enough to do sth.结构。He ran so fast that he caught up with us quickly. =He ran fast enough to catch up with us quickly. 他跑得飞快，很快就赶上了我们。2. 在sothat句型中，当主句和从句都是肯定式，但主、从句的主语不一致时，可简化成enough for sb. to d

43、 to school. =He is not old enough to go to school. 他还没到上学的年龄。如果主从句的主语不一致，须在to do sth.前加for sb. 作为不定式的逻辑主语。The problem is so difficult that we cant work it out. =The problem is too difficult for us to work out. =The problem isnt easy enough for us to work out. 这道题太难了，我们解答不出来。【课堂变式】根据上句改写下句，且使上下两句意思相同

46、ut.V.+out 短语总结：give out分发；发放 hand out分发；发放 work out 得出（结果；总数等）run out of 用光；耗尽 go out 出去；熄灭 find out 查明；弄清look out 当心 take out 拿出过去完成时一、过去完成时的概念与结构特点 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 构成：主语+had+过去分词（p.p），其中 had 通用于各种人称。They had already had breakfast be

47、fore they arrived at the hotel. She had finished writing the composition by 10 ：00 this morning. 肯定句：主语+had+过去分词. 否定句：主语+had+not+过去分词. 一般疑问句：Had+主语+过去分词? 肯定回答：Yes,主语+had 否定回答：No,主语+hadn't 特殊疑问句：特殊疑问词或词组+一般疑问句（Had+主语+过去分词）？ 被动语态：主语+had（hadn't)+been+过去分词二、过去完成时的判断依据 1. 由时间状语来判定 一般说来，各种时态都有特定的时

48、间状语。与过去完成时连用的时间状语有： （ 1 ） by + 过去的时间点。如： I had finished reading the novel by nine o'clock last night. （ 2 ） 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. （ 3 ） before + 过去的时间点。如： They had planted six hundred trees before last Wednesday. 2. 由“过去

49、的过去”来判定。 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： （ 1 ）宾语从句中 当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如： She said that she had seen the film before. （ 2 ）状语从句中 在时间、条件、原因、方式等状语从句中，主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。如

50、： When I got to the station, the train had already left. After he had finished his homework, he went to bed. 注意： before, after 引导的时间状语从句中，由于 before 和 after 本身已表达了动作的先后关系，若主、从句表示的动作紧密相连，则主、从句都用一般过去时。如： Where did you study before you came here? After he closed the door, he left the classroom. （ 3 ）表示意

51、向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本，未能" We had hoped that you would come, but you didn't.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.三、过去完成时的主要用法 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

52、去的过去”。 When I woke up, it had stopped raining. 我醒来时，雨已经停了。（主句的动作发生在“过去的过去”） 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。 He told me that he had written a new book. (had written 发生在 told 之前 ) 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

53、， before ， until 等引导的短语或从句连用。Before she came to China, Grace had taught English in a middle school for about five years. Peter had collected more than 300 Chinese stamps by the time he was ten. 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。By the end of last year, he had worked in the

54、 factory for twenty years. （ had worked 已有了20 年，还有继续进行下去的可能）5. 过去完成时还可用在hardlywhen, no soonerthan(刚就), It was the first (second, etc) time (that)等固定句型中。 Hardly had he begun to speak when the audience interrupted him. 他刚开始演讲，听众就打断了他。 No sooner had he arrived than he went away again.他刚到就又走了。 It was the third time that he had been out of work that year. 这是他那一年第三次失业了。四、过去完成时与现在完成时的区别 现在完成时表示的动作发生在过去，但侧重对现在产生的结果或造成的影响，与现在有关，其结构为“助动词 have (has) + 过去分词”；过去完成时则是一个相对的时态，它所表示的动作不仅发生在过去，更强调“过去的过去”，只有和过去某时或某动作相比较时，才用到它。 I have learned 1000 English words so f
