2、finished writing the composition by 10: 00 this morning.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 oclock 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 ) befo
3、re +过去的时间点。如： They had planted six hundred trees before last Wednesday.2.由过去的过去”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，从句要用过去完成旺。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 )
4、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：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
5、?After he closed the door, he left the classroom.（3 ） 表示意向的动词， 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 didnt.3.根据上、下文来判定。I met WangTao in the street yesterday. We hadnt 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
6、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”。如：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。如：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
7、, before , never 等时间副词及 by , before , until等引导的短语或从句连用。如： Before she came to China, Grace had taught English in a middle school forabout 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。如： By the end of la
8、st year, he had worked in the factory for twenty years.（had worked 已有了 20年，还有继续进行下去的可能）5 .用在特定的句型中：no sooner than , it was the first timeIt was the first time he had been to Beijing.No sooner had he arrived at the airport than the plane took off.下列情况一般不能用过去完成时下列三种情况不用过去完成时：1、句中如 yesterday , last yea
9、r , in 1986 , three days ago等明确地表示过去时间的状语，谓语动词必须用一般过去时。_02欢迎下载精品文档例如：Peter didnt play football yesterday .（彼得昨天没有踢足球。）2、在叙述两件以上的事件时，如果事件之间连接地很紧凑的一系列的动作，一般仍用一 般过去时而不用过去完成时。例如： They decided to stay here , and so they built their houses and made their farms .（他们决定呆在这儿，所以他们建了房子，开垦了农场。 ） 四、过去完成时与现在完成时的区别
10、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。试比较：I have learned 1000 English words so far.到目前为止我已经学会了1000个英语单词。I had learned 1000 English words till then.到那时为止我已经学会了1000个英语单词。一Im sorry to keep you waiting.对不起，让你久等了。Oh
11、, not at all. I have been here only a few minutes.没什么，我只等了几分钟。（等”的动作从过去某一时间点持续到现在）John returned home yesterday.约翰昨天回至 U家的。-Where had he been?他去哪儿了？（答语中使用过去完成时是指约翰在returned home之前去了哪些地方，即过去的过去”）五、过去完成时与一般过去时的区别虽然这两种时态都表示过去发生的动作或存在的状态，但在使用时应注意以下几点：1 .时间状语不同：过去完成时在时间上强调过去的过去”；而一般过去时只强调过去某一特定的时间。试比较：The
12、y had arrived at the station by ten yesterday.They arrived at the station at ten yesterday.2 .在没有明确的过去时间状语作标志时，谓语动词动作发生的时间先后须依据上下文 来判断：先发生的用过去完成时，后发生的则用一般过去时。如：She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition.3 .当两个或两个以上接连发生的动
13、作用and或but连接时，按时间顺序，只需用一般过去时来代替过去完成时；另外，在 before , after , as soon as 引导的从句中， 由于这些连词本身已经表示出时间的先后，因此也可以用过去时来代替过去完成时。如：He entered the room, turned on the light and read an evening paper.I （had） called her before I left the office.重点英语中，已经有了一个过去一般时表示在过去发生的动作，为什么还有过去完成时呢？要记住：过去完成时的关键概念是：假设在过去发生了两件（或以上）的事
14、件，一件是A事件,另一件是B事件，如果A、B两个事件几乎是同时发生的，那就用一般过去时；但是，如果 A、B两个事件不是同时发生的，怎么办呢？那就是：哪个事件先发生，就用过去完成时； 哪个事件后发生，就用过去完成时。例 1 She said （that） she had never been to Paris.例 2 When the police arrived, the thieves had run away.例 3 We had hoped that you would come, but you didnt.例 4 Tom was disappointed that most of t
15、he guests had left when he arrived at the party.例 5 The students were writing, busily when Miss Brown went to get a book she had left in the office.在上面的五个例子中，我们只要稍微分析一下，就可以发现：每个例子讲述的内容中， 都包含着两个（或以上）在过去发生的事件。 我们将两件事抽取出来看一下，就非常明白：必定有一件事是先生的，另一件是后发生的：例 1 said had never been to （先没有 去，后 说）例 2 arrived ha
16、d run away.（ 先 跑”了，后 到”）例 3 had hoped would comedidnt （ 先 希望”，后才发生 没去”）例 4 was disappointed had left arrived （ 先 离开“，后 到达和 失望）例 5 were writing went had left （先 离开“，后 到和 写）难点例 1 By the time he was twelve, Edison had began to make a living by himself.所以，在那么多表示时间状语的词中，大家要特别注意By、如果出现By时间状语，很有可能要用过去完成时了。
