英语现在完成时

英语现在完成时 现在完成时表示到说话时为止（或到现在为止）已经发生或完成了（不一定结束）的动作或状态。过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态。 a. 现在完成时的句型 ①肯定句：主语+has/have+动词的过去分词+宾语（或者其他） ②否定句：主语+haven’t/hasn’t+动词的过去分词+宾语 ③一般疑问句：Have/Has+主语+动词的过去分词+宾语（或者其他）.（末尾用问号） b. 现在完成时的用法 1) 表示影响 该用法的现在完成时表示一个过去发生的动作在过去已经完成，并且这个过去发生并完成的动作对现在有影响或结果，同时说话者强调的或感兴趣的就是这个影响或结果，如汉语说”他已离开这个城市了”，其中的”离开”肯定发生了，它对现在的影响或结果就是”他现在已不在这个城市了”；又如汉语说”有人把窗户打破了”，显然”打破窗户”这一动作发生在过去，并且在过去已经完成了，但说话人强调的重点是打破窗户对现在的影响–窗户现在仍是破的。如： He has been away from the city.他已离开这个城市。(结果：他不在这个城市。) Someone has broken the window.有人把窗户打破了。(结果：窗户仍破着。) I have lost my pen.我把钢笔丢了。(结果：我现在无钢笔用。) He has finished his work.他把工作做完了。（结果：他现在可以做其他的事了。） 2) 表示持续 该用法的现在完成时表示一个过去发生的动作或开始的状态在过去并未完成或结束，而是一直持续到现在，并且有可能继续下去(也可能到此结束)，如汉语说”他在我们学校教书已有30年了”，显然”他在我们学校教书”是从30年前开始，并且一直教到现在，已经持续了30年；又如汉语说”自上个星期以来他一直很忙”，显然”忙”是从上个星期开始的，并且这一”忙”就一直忙到现在。如： He has taught in our school for 30 years.他在我们学校教书已有30年了。 He has been busy since last week.自上个星期以来他一直很忙。 He has worked for us ever since he left school.他离开学校以后就一直为我们工作。 3) 表示重复 即表示从过去某个时间直到现在的这个时间范围内不断重复发生的动作或情况，并且这个不断重复的动作有可能继续下去，也有可能到现在就结束。如：

一般过去时与现在完成时的用法区别

一般过去时与现在完成时区别专题 一、前言： 初一下学期同学们学习了一般过去时态的相关知识，即将到来的初二上学期英语学习中，现在完成时是重要的学习内容。本文通过对比一般过去时和现在完成时，对现在完成时进行初步讲解，希望使同学们读新学期的学习有所准备。 二、现在完成时 1. 现在完成时的构成 现在完成时是由助动词have (has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。 2. 现在完成时的用法 现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。 We are good friends.(现在的情况） I knew him in 1997.（过去的动作） We have known each other since 1997. （现在完成时把过去的动作和现在联系起来并着眼于现在） （1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如： -Have you had lunch yet? -Yes, I have. I've just had it. 你（已经）吃午饭了吗？我刚刚吃过。（现在我不饿了） （2）表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，可能仍然在进行。常带有for和since等表示一段时间的状语。 如：He has taught here since 1981 他自1981年就在这儿教书。（可能还要继续教） I haven't seen her for four years. 我有四年没见到她了。 （3）表示说话前发生过一次或多次的动作，现在成为一种经验，一般译为汉语“过”，常带有twice,ever, never,three times等时间状语。 如：I have been to Beijing twice.我去过北京二次。 3.现在完成时的时间状语 （1）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。 b.用ever 和never。多用于否定或疑问句中，表示“曾经”或“从未“等。 如：-Have you ever been to the Great Wall? 你曾经去过长城吗？ -I have never been to the Great Wall.我从未去过长城。 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。 例如：I have seen her before, but I can not remember where. 我以前见过她，但记不起在哪里见过。

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.

The old man has ______ _______ for 4 months. They have _____ _____ only for 5 minutes. 3）have (has) been 和have (has) gone的区别：表示“曾到过某地”要用“have (has) been”; 表示“已经去某地”要用“have (has) gone”。试比较： Where has he been? 他刚才到哪里去了？（已经回来了） Where has he gone? 他上哪儿去了？（人不在） They have been to Canada. 他们到过加拿大。（现在已经不在加拿大） They have gone to Canada. 他们到加拿大去了。（可能在路上和已经到加拿大）. 4）现在完成时不能和表示过去的时间状语连用，如yesterday, last year, in 1976, two days ago, just now, when I came in，但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用。例如：

一般过去时态和现在完成时态的区别练习题

一般过去时态和现在完成时态的区别练习题 1）一般过去时态表示过去某时发生的动作或单纯叙述过去的 事情，强调动作；现在完成时态中动作为过去发生的，强调过去的事情对现在的影响，强调的是影响。如:I saw this film yesterday. （强调看的动作发生过了） I have already seen this film.（强调对现在的影响，电影的内容已经知了） I haven’t finished my work yet. (强调对现在的影响，还有工作要做，不能去玩) When did you finish your homework? (询问过去的动作所发生的时间，与现在无关) 2）一般过去时态表示动作在过去已经停止；现在完成时态表 示过去开始的动作一直延续到现在。 如：Ann visited her uncle last weekend.(visit这个动作在过去已经停止) They have lived here since 1983. (live here 这个动作从1983年开始，一直延续到现在) 3）一般过去时态常用非延续性动词，如borrow, buy, come, go, leave, start, die, finish, become等。现在完成时态可表示持续到现在的动作或状态，与时间段连用时动词一般是延续性的，如keep, have, live, teach, learn, work, study, know, be等。如：He joined the League three years ago .(join 是短暂动词）

He has been in the League for three years.（be in表状态，在团内的状态可延续） He has been a League member for three years. （是团员的状态可延续） 4）一般过去时态常与具体的时间状语连用，而现在完成时态通常与模糊的时间状语连用，或无时间状语。 一般过去时态的时间状语：yesterday, last night/week/month/year…，…ago, in1980, just now等，皆为具体的时间状语. 现在完成时态的时间状语：for+时间段, since+过去的时间点/一般过去时态的句子, so far, , up to now, in the past ....years, 等，皆为不确定的时间状语。如：Tim wrote a letter to his brother last night. （last night 为具体的过去时间状语，所以用一般过去时态） I’ve learned English for three years . （for three years为时间状语，是个时间段，时间跨度大，不具体） 学以致用 1．——When _____ you _____ to learn to skate? ----Five years ago.
