一、过去完成时适用场合
1. 过去完成时表示在过去某一时间或动作以前已经完成了的动作。这个过去的时间常用by，before等介词短语或一个时间状语从句表示，也可以暗含在上下文中。
I had finished my homework before supper.我在晚饭前就把作业做完了。
The play had already started when we got to the theatre. 我们到剧场时戏已经开始了。
By the end of June they had treated over 10,000 patients. 到六月底他们已经治疗了一万多病人。
2. 过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或还要持续下去，常与for，since等词连用。如：
He had served in the army for ten years before he retired last year. 他在部队干了十年，去年退役了。
He told me that he had known her since he was a child. 他告诉我他从小就认识她。
He had learned English for eight years before he went to England for further study. 他在去英国深造前，已学了八年英语。
3. 在一段情景连贯的文字中，先发生的事放在后面叙述时，要用过去完成时。如：
Tom flew home, but his father had already died. 汤姆乘飞机回家，他的父亲却已经去世了。4. 过去完成时也用于hardly...when..., no sooner...than..., It was the first time + that分句等一些固定句型中。
He had no sooner left the room than they began to talk about him. 他刚离开房间，他们就议论起他来。
We had hardly begun when we were told to stop.
我们刚开始就被叫停。
It was the first time that he had ever spoken to me in such a tune.他用这样的语调跟我讲话，这是第一次。
二、过去完成时与一般过去时的比较
1. 当一个由before, after, as soon as 等连词引导的从句所表示的动作和主句的动作紧接着发生时，两个动作均可用一般过去时来表示。
We had breakfast after we did morning exercises.
做完早操后，我们吃早饭。
The train started to move just before he reached the platform. 他到月台时火车刚开走。
They started ploughing as soon as they got to the fields. 他们一到地里就开始耕地。
2. 按时间顺序叙述两个或两个以上接连发生的动作时，用一般过去时。
He entered the room, turned on the light and sat down at the table. 他走进屋子，打开灯，坐在桌子旁。
3. 在表示某人过去未曾完成的“心愿”、“打算”、“计划”、“想法”、“许诺”等时，hope, mean, plan, think, intend等谓语动词常用过去完成时。
I had hoped to be back last night, but I didn’t catch the train. 我本来希望昨晚回来的，但没搭上火车。
We had thought to return early but they wouldn’t let us go. 我们本想早回来的，但他们不让我们走。
4. 在表示过去的句子中出现常与完成时态连用的词，如：already，yet，since，for，ever，never及次数名词等时，常用过去完成时来表示。
When we got there the basketball match had already started. 我们到那里时，篮球赛已经开始了。
The old man said that he wanted to go where he had never been. 老人说他想到他从未去过的地方去。
5. 如果句中出现了表示具体的过去时间的状语，句子的内容为过去的实际情况或句子的内容为历史事实时，句中的动词时态常用一般过去时。如：
The teacher said that it was Columbus who first discovered the American continent.老师说是哥伦布最早发现了美洲大陆。
6. 表述说话人始料未及的事情时，句子的谓语动词常用一般过去时。由于受汉语表述习惯的影响，常会用错时态。
Jack, you are also here! I didn’t see you. 杰克，你也在这啊！我没有看见你。

浅析现在完成时态的用法 现在完成时是由助动词have(has)+动词的过去分词构成。 一，用法其主要用法有三种： I已完成用法 表示一个过去发生并结束的动作对现在产生的结果和影响。这一类情况可以细致分为下述两种情况。 1）.表示开始于过去的动作刚刚结束。常和just，now，already，yet，not…yet等连用。 Li Ming has just turned off the light. 李明刚刚把灯关上。（说明现在灯关上了） I've finished my homework now. 现在我已经做完作业了。（说明可以交作业或做别的了） 2）. 表示过去动作的结果，现在仍残留着。一般不用时间状语。 I have lost my pen. 我把笔丢了。 （说明过去某时丢的，现在我还没找到这支笔） She has become a teacher. 她已经当了老师。（说明她现在仍是老师） She has become a teacher. 她已经当了老师。（说明她现在仍是老师） II未完成用法。表示过去已经开始，持续到现在，而且还能继续下去的动作或状态。往往和表示一段时间的状语连用。如today，this week（month），lately，recently，these days，in the past few days，during the last two weeks. since，since yesterday，since 2 days ago，since 1991，for a longtime，for a month，so far，up to now，till（until）now等。 He has lived here for 30 years. 他住在这儿三十年了。（现在还住在这儿） They've known each other since childhood. 他们从小彼此相识。（现在还继续往来） How long have you studied English？ 你学英语多久了？（现在仍在学） III经验性用法。表示从过去到现在之间曾经经历过的事情。一般译为汉语“过”，常和often，never，ever，once，twice，three times，before，since等连用。 I have been to the Summer Palace twice. 我曾经去过颐和园两次。 We have visited your school before. 我以前曾去过你们学校。 （过去的经历，但现在依然记得） 二，现在完成时的时间状语 I现在完成时属于现在时范围，故不能和过去的时间状语连用。如：yesterday,last Sunday,in1990,three years ago等。但是，在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用。 a. 用副词already和yet。already一般用于肯定句中，yet一般用于否定句和疑问句中。如：We have already finished our homework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。

过去完成时态 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或呈现的状态， 即“过去的过去（past-in-the-past ）”。 二、构成：过去完成时由“助动词had + 过去分词”构成，其中had 通用于各种人称。 e.g. They had already had breakfast before they arrived at the hotel. She had finished writing the composition by 10 ：00 this morning. 三、句式：它的否定句是在had后边加not，变一般疑问句是把had提前。 肯定答语：Yes, 主语+had 否定答语：No，主语+hadn’ｔ e.g. I had reached the station before 9:00 o'clock. I had not reached the station before 9:00 o'clock. Had you reached the station before 9:00 o'clock? Yes, I had. No, I hadn’t. 四、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。如： 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） 五、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，

英语三种主要完成时的用法总结及练习题
一.现在完成时的构成: have(has)+done 二.现在完成时的主要用法: I.“已完成”用法 :表示一个过去发生并结束的动作对现在造成的影响或结果。 这一类情况可以细致分为下述两种情况。 1）表示开始于过去的动作刚刚结束。常和just，now，already，yet，not…yet等不确定的时间状语连用。 2）表示过去动作的结果，现在仍残留着。一般不用时间状语。 I have lost my pen. 我把笔丢了。（说明过去某时丢的，现在我还没找到这支笔） She has become a teacher. 她已经当了老师。（说明她现在仍是老师） II.“未完成”用法。表示动作或状态从过去某时开始，持续到现在，可能继续下去，也可能刚刚结束。常和表示一段时间的状语连用。如today，this week（month），lately，recently，these days，in the past few days，during the last two weeks，since，since yesterday，since 2 days ago，since 1991，for a long time，for a month，so far，up to now，till（until） now等。 He has lived here for 30 years. 他住在这儿三十年了。（现在还住在这儿） III.经验性用法:表示从过去开始到目前为止这段时间中反复发生的动作或多次出现的状态。 常与频度副词如often,always,every week,twice等连用。 I have been to the Summer Palace twice. 我曾经去过颐和园两次。 He has always said so.他总是这么说. 三.现在完成时的时间状语 I现在完成时属于现在时范围，故不能和过去的时间状语连用。如：yesterday,last Sunday,in1990,three years ago等。但是，在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用。 a.用副词already和yet。already一般用于肯定句中，yet一般用于否定句和疑问句中。 b.用ever和never.多用于否定或疑问句中，表示“曾经”或“从未“等。 c.用表示到说话为止的过去时间状语，如just, before, up to now, the past few years等。 d. 用包括“现在”在内的时间状语，如now,today,this morning(month,year,term)等。例如：-Have you met him today?-No,I haven't. 今天你见过他吗？我没有。
人教版英语英语现在完成时用法总结含答案推荐精选 一、初中英语现在完成时 1．—Where is Catherine? I haven't seen her for days. —She Wuhan. She'll be back next week. A. has gone to B. has been to C. have gone to D. have been to 【答案】 A 【解析】【分析】句意：——Catherine在哪里？我好几天没见她。——她已经去武汉了。她将下周回来。主语是she，所以用has，排除C、D。A.已经去了某地，在去的路上，还没有回来；B.已经去过某地，表示去了某地，并且回来了。根据She'll be back next week.她下周回来可知现在还没有回来，故选A。 【点评】考查短语辨析，注意平时识记其区别，理解句意。 2．Mike used to be a top student, but he behind since he lost himself in computer games. A. fell B. has fallen C. was D. has been 【答案】 D 【解析】【分析】句意为“Mike过去是尖子生，但自从迷上电子游戏以来成绩落后了”。由since可知but后的主句用现在完成时，瞬间动词fall不能和since引导的时间状语从句连用，故用延续性动词be。故选D。 【点评】本题考查现在完成时中非延续性动词和延续性动词的转换。 3．The Greens many places of interest since two years ago. A. has visited B. have visited C. visited D. will visit 【答案】 B 【解析】【分析】句意:自两年前开始，格林一家参观了许多名胜。since引出的时间状语从句，强调主句谓语从过去某时一直延续到现在，主句用现在完成时态，the Greens格林一家，表示复数含义，作主语，谓语用复数形式。故选B。 4．—Your new bike is so nice! When did you buy it? —In July. I _____it for two weeks. A. had B. have had C. have bought D. bought 【答案】 B 【解析】【分析】句意：——你的新自行车那么好看。你什么时候买的。——七月份，我买了两周了。根据for two weeks，可知句子时态为现在完成时，而且谓语动词必须是延续性的。因此排除AD，buy是结束性动词，不能够延续，应此排除，故答案是B。

英语计划总结之现在完成时用法小结 现在完成时是中学生必须掌握的重要语法项目之一,也是难点之一,要想让学生灵活掌握这一要点,必须对其用法进行深析和加强实际运用. 一、现在完成时的构成 现在完成时是由“have/has+动词的过去分词”构成.其中的have/has在这里只充当助动词,故将肯定式变成否定式时直接在其后面加not,变成疑问句时直接将其提前. 二、现在完成时的含义 表示过去发生或已经完成的某个动作对现在所造成的影响或结果,重在与现在的联系.如： I have finished my homework already. He has never been to England. 2. 表示动作或状态从过去某时开始,一直持续到现在,并有可能会持续下去.如： I have lived here for ten years. I have lived here since ten years ago. 三、运用现在完成时的几个注意点 1. 熟记与现在完成时连用的时间状语.
already,yet,before, ever, never, before, recently, just, many times, until now, up till now, so far, since 2000, for ten years, in the past/last five years, these days等. 2. 注意现在完成时与一般过去时的区别. 一般过去时只是单纯地表示过去的动作或状态,和现在不发生联系,它要和表示过去的时间状语连用.而现在完成时表示的是过去的某一动作对现在造成的影响或结果.强调的是现在的情况,它不能和表示过去的时间状语连用.两种时态的侧重点不同,前者强调的是动作本身,后者则强调结果.比较： I lost my watch yesterday.（至于现在找到与否没有说明,即不跟现在发生联系） I have lost my watch…（表示现在的结果——手表未找到） 3. 当现在完成时与since,for引导的时间状语连用时,其谓语动词必须是延续性动词,如果是终止性动词,必须将其转换成延续性动词.如： I borrowed this book two days ago. I have kept this book for two days. I have kept this book since two days ago. 常见的终止性动词与延续性动词的转换有：become; come—be here; go—be there; begin—be on; open—be open; close—be close;
