去完成时(The Past Perfect Tense)：表示过去某一时间或动作以前已经发生或完成了的动作，对过去的某一点造成的某种影响或是结果，接下来小编为大家介绍初一英语学习的相关内容，一起来看看吧!
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、常搭配的时间状语：before, by the end of last year(term, month„),etc.
三、基本结构：had + 动词的过去分词(done). (had通用于各种人称)
否定形式：had + not + 动词的过去分词done.
一般疑问句：had放于句首。
例句：She said she had never been to Paris. 她说她从未去过巴黎。
When the police arrived, the thieves had run away. 警察到达时，小偷们早就跑了。
By the time he was twelve, Edison had begun to make a living by himself. 到了十二岁那年，爱迪生开始自己谋生。
四、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 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：
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.
五、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 ， 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 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 factory for twenty years.
( had worked 已有了 20 年，还有继续进行下去的可能)
六、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。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。
- I'm sorry to keep you waiting. 对不起，让你久等了。
- Oh, 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. 约翰昨天回到家的。
- 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")
七、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：
They 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.
特殊用法：过去完成时用法之表未曾实现的想法
过去完成时可表示过去未曾实现的想法和打算，通常连用的动词是 want, think, hope, plan, mean, expect, intend, suppose 等：
I had meant to come, but something happened. 我本想来，但有事就没有来。
I had intended to speak, but time did not permit. 我本想发言，但时间不允许。
We had hoped that you would come to see us, but you didn’t. 我们本想你来看我们的，但你没有来。

初一英语学习方法
1、养成良好的预习习惯
课前预习是独立获得知识的前提，也是提高听课效率的可靠保证。预习能减少听课的盲目性，激发你的求知欲望。预习可使自己初步熟悉教材，发现疑点和难点，找出自己的薄弱点，为下一步听讲作好充分的思想准备，并打下一定的基础。
如何进行预习：
1) 找出该单元的中心话题，即该单元的中心内容。
2)明确本单元的知识要点：如语法项目、句型及词汇，
3) 找出本单元的疑、难点。凡是在本单元出现而自己无法解决的知识点，即是重点，也可以说是难点。预习时，在书上作记号，标明重点、难点、疑点，并在笔记本上做好记录，注明本单元的知识结构、重、难点和预习体会等。
2、养成课堂上记笔记、积极发言、大胆回答问题的习惯
学生在课堂上认真听讲，注意力高度集中，不开小差;保持强烈的求知欲，积极思考老师提出的问题，踊跃发言，努力解决在预习中存在的问题，并作好课堂笔记，重点突出，难点醒目，疑点鲜明。以便复习时可以查阅。努力在课内有目标有意识地去识记该课的生词、短语、句型、重点句子。然后要注意一些语言在特定环境中的运用，特别是习惯表达法的运用。在运用中，要主动地用英语回答、讨论和提出问题，并注意角色扮演或做游戏等活动。初中生的英语知识主要还是从课堂上获得。
教师起的只是导演作用，关键是需要学生作为演员，积极投入，在参与的过程中提高听说读写能力和语言运用能力。因此，学生养成良好的听说读写训练习惯尤为重要，这是向课堂四十五分钟要质量的根本保证。有一小部分的学生怕害羞、怕出差错，不敢开口讲，这会给初中英语学习带来不利。俗话说：没有缺点，就不会进步。学生应该注意模仿并主动与教师配合，做一名好演员。
不要怕出错，今天说不好，不代表明天说不好;今天说得少，明天说得多，就是进步;别人这样表达，你能那样表达，你就有了创新。只有大胆实践、体会，才能得到巩固提高。
3、养成朗读背诵英语的习惯
英语是一门有声语言。学英语就要背诵，尤其是我们在母语环境下学习英语，首先要过好语音关。听清楚了再发音，继而进行朗读、背诵。“读书百遍，其义自见”就是其道理所在。在读、背的过程中，可以做到词不离句，句不离文，不知不觉间增强了语感，记牢了单词、短语和句型，同时也培养了理解能力，其实朗读背诵是学生记单词的最佳途径。因此，学过的句型、对话和课文要求学生朗读和背诵，这是提高英语水平的根本保证。
