过去完成时语法精讲 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：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。 They had already had breakfast before they arrived at the hotel. # She had 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 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.
第2讲：现在完成时 现在完成时的定义： 现在完成时表示过去的动作对现在造成的影响；而与一般过去时相比，一般过去时表示动作发生的时间在过去。试比较: The plane has arrived. 飞机已经来了.(说明现在的情况,飞机在这儿.) The plane arrived an hour ago. 飞机是在一小时前抵达的(强调动作发生的时间.) 现在完成时的结构： 肯定句: 主语＋have/has＋过去分词（done） Lily has returned from America. ★变否定句在have/has后面加not 主语＋have/has＋not+过去分词（done） Lily has not returned from America. ★变一般疑问句将have/has移到句首 主语＋have/has＋not+过去分词（done） Has Lily returned from America? 肯定回答及否定回答：Yes，she has./ No， she hasn’t. ★变特殊疑问句特殊疑问词+一般疑问句 特殊疑问词（how/what/why/when/where）＋have/has＋主语＋过去分词(done) Where has Lily returned from? 现在完成时的用法： 在学习这一概念的同时，还应注意常与现在完成时连用的几个副词：already，just，ever，yet，never等。already，just多用于肯定句中，ever，yet，never多用于疑问句和否定句中。如： I have already finished my homework．我已经做完家庭作业了。 He has just had his meal．他刚吃过饭。 Have you ever sung this English song？你曾唱过这首英文歌吗？ They haven't started yet．他们还没有动身。 We have never heard of it．我们从来没有听说过这件事。
英语现在完成时语法详细讲解与配套习题 一、现在完成时用来表示之前已发生或完成的动作或状态，但它的影响现在还存在；也可表示持续到现在的动作或状态。其构成： have (has) +过去分词。规则变化的过去分词与过去式的变化一样，在动词词尾加ed; 不规则变化的过去分词见不规则动词表，需要同学记忆。 现以see the film为例将现在完成时的肯定句，否定句和疑问句列表如下： 肯定句：I/You/We/They have seen the film. He/She /It has seen the film. 否定句：I/You/We/They have not/ haven’t seen the film. He/ She/It has not/hasn’t seen the film. 疑问句：Have I/you/they seen the film Yes, you/ we/I/they have. No, you/ we/I/they haven’t. Has he/she/it seen the film Yes, he/ she/ it has. No, he/ s he/ it hasn’t. 二、用法：现在完成时既涉及过去，又联系现在。 标志词词义用法位置 already已经肯定句句中或句末 ever曾经疑问句、肯定句句中 never从未，从来不陈述句，不和not 连用句中 (ever)since自从肯定、疑问、否定句中 for后接一段时间肯定、疑问、否定句中 just刚刚，正好肯定句句中 yet还疑问句、否定句末 recently最近肯定、否定、疑问句句末 once, twice, a few times几次肯定、疑问句末 during/over /in 在过去的一段时间里肯定、疑问、否定句末 the past/last + 一段时 间 It’s the first time I …这是我第一次…肯定句前

By the time he was ten, he had made a lot of money. 2.她说她已经吃过早饭了。 She said she had had breakfast. 过去完成时常常用在told, said, knew, thought等动词的宾语从句中，这时从句中的动作发生在主句表示的过去的动作之前。 练习： She said she ______ (see) the film before.

过去完成时 （1）表示在过去某一时刻或动作以前完成了的动作，可以用by, before等介词短语或一个时间状语从句(在复合句中，由时间连接词引导的状语从句叫做时间状语从句)来表示，也可以用一个表示过去的动作来表示，还可能通过上下文来表示。 例；By nine o’clock last night, we had got 200 pictures from the spaceship.到昨天晚上9点钟，我们已经收到200 张飞船发来的图片。 （2）表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态，常和for, since 构成的时间状语连用。 例；I had been at the bus stop for 20 minutes when a bus finally came.我在车站已经等了20分钟,一辆公共汽车终于来了。 He said he had worked in that factory since 1949.他说他自从1949年以来他就在那家工厂工作。 （3）叙述过去发生的事情，在已叙述了过去发生的事情后，反过来追述或补充以前发生的动作时，常使用过去完成时。 例；Mr. Smith died yesterday. He had been a good friend of mine. 史密斯先生昨天就去世了。他以前是我的好朋友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知，因为我没有好好学习功课。 （4）在含有定语从句的主从复合句中，如果叙述的是过去的事，先发生的动作常用过去完成时。 例；I returned the book that I had borrowed.我已归还了我借的书。 She found the key that she had lost.她发现她失去了的钥匙。 （5）过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句（或间接引语）中，这时从句中的动作发生在主句表示的过去的动作之前。 例；He said that he had known her well.他说他早就很了解她了。 I thought I had sent the letter a week before.我认为我一星期前就把信寄出去了。（6）状语从句：在过去不同时间发生的两个动作中，“发生在过去的过去”，用过去完成时；发生在后，用一般过去时。 如when,before,after,as soon as,till/until引导的 e.g：When I woke up, it had already stopped raining.我醒来时雨已停了。 She didn’t go to bed until she had finished her work.她直到把工作做完之后才睡觉。 注意：如果两个动作紧接着发生，则常常不用过去完成时，特别是在包含before和after 的复合句中，因为这时从句的动作和主句的动作发生的先后顺序已经非常明确，这时可以用一般过去时代替过去完成时。 e.g：After he arrived in England, Marx worked hard to improve his English. 马克思到达英格兰之后，努力提高他的英语水平。 （7）动词think, want, hope, mean, plan, intend等用过去完成时来表示过去未曾实现的想法，希望，打算或意图等。 e.g：They had wanted to help but could not get there in time. 他们本来打算去帮忙，但没有及时赶到那里。 We had hoped to be able to come and see you . 我们本来希望能来看看你。 （8）过去完成时还可用在hardly when no sooner than It was the first
（Present Perfect）。 第一部分 现在完成时表示过去发生或已经完成的动作对现在造成的影响或结果,也可表示过去已经开始,一直延续到现在的动作或状态。学习现在完成时,先从结构和句式开始: 构成:主语 + have/has + 过去分词 + 其他。(当主语是第三人称单数时用has,其余人称用have。过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。) 否定式:主语+ haven't/hasn't + 过去分词+ 其他。 疑问式: Have /Has + 主语+ 过去分词+ 其他? 简略答语: Yes, 主语+ have/has.(肯定) No, 主语+ haven't/hasn't.(否定) 现在完成时常用的时间状语有： already （”已经”用于肯定句的中间和末尾处） never (“从不”用于中间处) ever （”曾经”用于疑问句和肯定句的中间处） just (“刚刚”用于中间处) yet (“已经”用于疑问句的末尾处/ “还”用于否定句的末尾处) 或不加任何的时间状语，但不能和表示过去的时间状语连用. 第二部分 现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义: * 以already, just和yet为标志 already, just和yet 表示到现在为止动作或状态已经、刚刚或还没有发生。 He has already got her help. 他已得到她的帮助。 He has just seen the film. 他刚刚看过这场电影。 He hasn't come back yet. 他还没有回来。 * 以ever和never为标志 ever和never 表示到现在为止动作或状态曾经或从来没有发生过。 This is the best film I have ever seen. 这是我曾经看过的最好的一部电影。 He has never been to Beijing. 他从没有到过北京。 * 以动作发生的次数为标志 若某一动作到现在为止已经发生了若干次,则要使用现在完成时。 He says he has been to the USA three times. 他说他已经去过美国三次了。 * 以so far为标志 so far往往表示到目前为止动作或状态已经发生。 He has got to Beijing so far. 到目前为止他已到了北京。 She has passed the examso far. 到目前为止她已经通过了。 第三部分 过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时。 *“终止”、“延续”要转换
