现在完成时(5)

延续性动词和终止性动词

延续性动词

表示能够延续的动作。如:study, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。延续性动词可以与for+段时间,since+过去时间点/…ago/过去时的句子连用。

He has lived here for 6 years. You can keep the book for 5 days.

I stayed there for 2 weeks last year. How long did you stay there last year?

终止性动词

也称非延续性动词、瞬间动词或点动词,表示不能延续的动作,这种动作发生后立即

结束。如:open, die, close, begin, finish, come, go, move, borrow, lend, buy, arrive等。终止性动词在现在完成时中的用法:

1)终止性动词可用来表示某一动作的完成,因此可用于现在完成时。

The plane has arrived飞机到了。

I have finished my homework.我已完成了作业。

2)终止性动词表示的动作极其短暂,不能持续,所以其现在完成时, 不能和表示一段时间的状语连用。如:

①他死了三年了。误:He has died for three years.

②他来这儿三个月了。误:he has come here for three months.

①②两句中的动词die和come都为终止性动词,它们可用于完成时,但不能同表示一段时间的状语for three years /months连用。那这两句如何译成英语呢?我们可采用下列

方法:

A.用能够表示持续状态的相应的延续性动词替换句中的终止性动词。如:

①He has been dead for three years.

②He has been here for three months.

B. 把时间状语改为表示过去的时间状语,把现在完成时改为一般过去时。如:

①He died three years ago.

②He came here three months ago.

两者的转换:

leave --- be away( from), borrow --- keep, buy --- have,

begin/start --- be on, die --- be dead, finish --- be over,

get up---be up, come here --- be here, go there --- be there, become --- be, come back --- be back, get to/ arrive/reach --- be (in), go (get) out →be out,put on→ wear

catch a cold →have a cold, join --- be in+…/ be a member of+…,

A. has been open B. open C. is opening D. opens 【答案】 A 【解析】【分析】句意:——他们说在这附近有一个新的餐馆。——是的,它已经开了一个多星期了。根据 for more than a week ,可知用现在完成时,have/has been done,故选A。 【点评】考查现在完成时,注意识记其标志词。 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.—Hi, Tom! you ever the Bird's Nest? —Yes, I have.

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。

现在完成时的用法讲解1

现在完成时的讲解 对所学时态的回顾,引入现在完成时 通过数轴来概括讲解所学的四个时态:一般现在时、现在进行时、一般过去时、一般将来时。 (导入)有时候,这4种时态还不能满足我们表达的需要。比如:表示“某人过去曾经做过某事”或者“某人做某事多久”,以上五种时态就派不上用场了。这时,我们可以用一种新的时态——现在完成时表示。同样也用数轴来表示一下。 taught will teech -------- ---------- -------- --------- ---------- ? —过去时now 垠时 is teaching fit在发生) -------- ---------- -------- --------- ---------- ?

现在完成时 一、定义:表示一个动作在过去发生并对现在产生影响 表示一个动作由过去发生持续到现在有可能停下,也有可能延续下去 表示一个动作从过去开始发生到目前为止已经发生多次。 二、构成:现在完成时是由“助动词have / has + 动词的过去分词”构成的, 其规则动词的过去分词构成与过去式相同,不规则动词的过去分词则需加强记忆。 如:I have just cleaned my clothes.我刚洗过衣服。 My brother has done his homework already. 我的弟弟已经做完他的作业了。 友情提示:在现在完成时的各种结构中,have, has均为助动词,无实际意义,只起构成时态的作用,不可省略。当主语是第三人称单数时助动词用has,其余人称一律用have。 过去分词 1 、规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。 四点变化规则: (1)、一般动词,在词尾直接加“ ed ”。 work---worked---worked ,visit---visited---visited (2)、以“ e ”结尾的动词,只在词尾加“ d ”。 live---lived---lived , (3)、以“辅音字母+ y ”结尾的动词,将"y" 变为"i" ,再加“ ed ”。 study---studied---studied ,cry---cried---cried , play---played---played ,stay---stayed---stayed (4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。 stop---stopped---stopped , drop---dropped--dropped 2 、不规则动词: AAA型 原型过去式过去分词 burst burst burst cast cast cast cost cost cost cut cut cut hit hit hit hurt hurt hurt put put put set set set shut shut shut

现在完成时的基本用法

现在完成时讲解与练习 (一)现在完成时的基本用法 (1)强调动作是从过去持续到现在,并有可能继续持续下去。 (2)强调对现在的影响或结果,此用法容易和一般过去时混淆。两者的区别是:一般过去时有动作发生的时间点,即过去某一时间发生某一动作;现在完成时则没有,即不强调是哪个时间点发生的动作,而强调过去的动作对现在造成的影响和结果。 (3)在过去不确定的时间里发生的动作,但是结果对现在有影响。一、现在完成时的构成 (一)肯定式 主语+助动词have /has +过去分词+其它 说明:这里的have /has是助动词,没有什么具体意义。当主语是第三人称单数时助动词用has,其余人称一律用have。has,have的缩略式分别为's或've。规则动词过去分词的构成与过去式的构成方式一样,不规则动词可参看不规则动词表。实例: 1)I've just copied all the new words .我刚抄写了所有的生词。(表示不要再抄了) 2)She has lost her books .她丢失了她的书。(表示到目前为止还没有找到) (如果用过去时:She lost her books . 则强调书是过去丢的这一动作,而不知现在有没有找到) 3)We've just cleaned the classroom .我们刚好打扫了教室。(表明现在教室是干净的) (二)否定式 主语+助动词have /has+not+过去分词+其它 说明:现在完成时构成否定句时,只需在助动词have /has后面加not就行。have not,has not的缩略式分别为haven't ,hasn't。另外,肯定句中有some,already时,改为否定时要分别改成any,yet。实例: 1)I haven't finished my homework yet.我还没有完成我的作业。 2)She hasn't travelled on a train .她没有坐火车旅行过。 3)We have never spoken to a foreigner.我们从来没有和外国人说过话。注:有时not可以用never代替,表示“从来没有”的意思。又如:

现在完成时的用法解析

Lead in 一般过去时导入:一般过去时的概念 一般过去时表示过去某个时间发生的动作或存在的状态。 I lost my pen.(过去时) I have lost my pen.(现在完成时) 过去时一般表示过去所发生的动作或存在的状态。“我把笔丢了”,说话人只是想告诉对方在过去的某一个时间里他的笔丢了,仅此而已。(仅仅是在陈诉过去的一个事实,与现在没有关系) New lesson 一.现在完成时的构成: 助动词have/has(not) +动词过去分词 She has turned on the lights. 肯定式:have/ has+过去分词 否定式:haven’t/hasn’t+过去分词 疑问式:把have/has 提到主语前面 肯定回答:Yes,…have/has 否定回答:No,…..haven’t/hasn’t 二.用法 1.表示过去发生的动作对现在造成的影响或结果. 例如:She has gone. 她走了. She went in the past.(She is not here

now.) I have just cleaned my hands. 我刚洗过手。(“洗手”是发生在过去的动作,对现在造成的结果是“手干净了”) I have closed the door. (The door is close now.) She has turned on the lights. (The lights are on now.) He has written his name on the blackboard. (The name is on the blackboard now.) Mother has cooked the dinner. (We can have dinner now.) You have seen the film. (You know what the film is about.) We have cleaned the classroom. (The classroom is clean now.) 2. 表示动作发生在过去,并且一直延续到现在,甚至还可能继续延续下去。这时常和since所引导的短语或从句或for引导的短语连用(for有时可以省去)。以及so far, by now, these days, in the last/past … years/days…等连用。 I have lived here for over ten years. (表示他现在还在这里居住,并且还有可能继续住下去)比较:I lived here ten years ago.(仅仅说明了他十年前在这里记住过的事实,不代表现在他还住在这里) He has studied here since 2006. 都用How long 提问,例: We have learned English for three years. We have learned English since three years ago.

现在完成时趣味讲解

现在完成时趣味讲解 现在完成时的含义 可与现在完成时态相连用的常见时间状语 瞬间动词在现在完成时态中的用法 现在完成时的含义 在当今常见的语法书中对现在完成时的定义大多是:现在完成时是指过去发生的至今已经完成或还在继续的动作。在笔者2011年于《海外英语》中发表的《have + -en的构式研究》中曾指出这一说法的稍欠妥之处。因为过去发生的“已经完成”或“未完成”容易让学生产生疑惑:究竟是不是完成时? 笔者认为易仲良教授提出的“式态”的说法以及马承老师提出的“现在完成时表示过去已经发生而与现在情况有关系的动作”这一说法更能让学生理解。事实上,我在初中的教学过程当中也是这样跟学生讲解的,学生们能够较好的理解这一说法,并能自然地将现在完成时与一般过去时区分开来。 常与现在完成时相连的时间状语 在初中阶段,多数考查现在完成时的句子当中都有较为明显的时间状语标志词, 比如以下的这些句子(均摘录自人教版教材):

Have you read Treasure Island yet? I’ve already read it. Have you ever been to a museum? I’ve never been to a science museum. I’ve had this bike for three years. 如果在实际的教学过程当中孤立地让学生记忆这些时间状语标志,无疑会给学生增大学习难度。为了能够提高学生的学习兴趣,我认为可以通过口诀韵律的方式让学生较快地掌握:以前(before)从来不(never)出现,最近(recently)曾经(ever)一两遍(once/twice/many times…), 自从(since+时间点)刚刚(just)for一段(for+一段),至今(so far/up to now)已经(already/yet)很明显。 在实际的教学过程当中,教师可有意识地讲述两个“已经”(already/yet)及(since/for)的区别着重分章节讲解,让学生在有了整体概念的基础上对各个考点进行突破。 瞬间动词在现在完成时中的用法 在人教版的课本附录的语法讲解中,我们可以看到:“某些动词的现在完成时可表示过去某一时间开始并一直持续到现在(包括”现在“在内)的动作或状态,可以和表示延续的时间状语连用。表示持续动作或状态的动词多是延续性动词”。如:

现在完成时的基本用法

现在完成时的基本用法 1、现在完成时表示影响 Hehasleftthecity.他已离开这个城市。(结果:他不在这个城市。) Someonehasbrokenthewindow.有人把窗户打破了。(结果:窗户 仍破着。) Ihavelostmypen.我把钢笔丢了。(结果:我现在无钢笔用。) Hehasfinishedhiswork.他把工作做完了。(结果:他现在可以做其他的事了。) 2、现在完成时表示持续 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语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: Hehastaughtinourschoolfor30years.他在我们学校教书已有30 年了。 Hehasbeenbusysincelastweek.自上个星期以来他一直很忙。 Hehasworkedforuseversinceheleftschool.他离开学校以后就一直为我们工作。 3、现在完成时表示重复

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: Howoftenhaveyouseenher?你隔多少见她一次? Myfatherhasalwaysgonetoworkbybike.我父亲一向骑车上班。 4、现在完成时表示将来 同一般现在时可以表示将来一样,现在完成时也可以在时间状语从句里表示将来。如: I’llwaituntilhehaswrittenhisletter.我愿等到他把信写完。 Whenyouhaverested,I’llshowyouthegarden.等你休息好之后,我领你看我们的花园。 二、现在完成时的基本定义和句型构成 基本定义 现在完成时有两种用法 1.过去发生的某一动作对现在造成的影响或结果。到现在为止已经发生或完成的动作。 2.表示过去发生的、持续到现在的动作或状态。 句型构成 基本结构:主语+have/has+动词的过去分词(p.p) 现在完成时用法 现在完成时用法 ①肯定句:主语+have/has+动词的过去分词(p.p)(V-ed)+宾语(或者其他). ②否定句:主语+havenot/hasnot+动词的过去分词(p.p)(V-ed)+宾语.

现在完成时的用法

现在完成时的用法 一、概念 现在完成时主要强调过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。 二、理解: 现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系。动作或状态发生在过去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。 四、基本用法: 1.已完成用法(影响性用法)。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 说话强调的或感兴趣的就是这个影响或结果。如:

He has left the city. 他已离开这个城市。(结果。如:他不在这个城市) Someone has broken the window. 有人把窗户打破了。(结果。如:窗户仍破着) Have you seen my bag? 你看到我的手提包了吗?(结果。如:你知道它在哪里吗?) I have bought two apples.我买了两个苹果。(“买”这一动作发生在过去,对现在造成的结果是:拥有两个苹果。) 【注】现在完成时“完成用法”的特点是动作不延续,因此,该时态只能与表示不定的过去时间状语(如:already,just, yet,before,recently等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的时间状语(如:this morning/month /year..., today等)连用。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。 2.未完成用法(持续性用法)。如:该用法的现在完成时表示一个过去发生的动作并未在过去完成,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)。此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相连的时间状语(如:up to now,so far到目前为止)等。如: He has lived here since 1971. 自从1971年以来,他一直住在这儿。 (动作起始于1971年,一直住到现在,可能还要继续住下去。) We have been in the army for more than 5 years. 我们在部队已经呆了五年多了。 (动作开始于5年前,一直延续至今,有可能还要继续下去。) Have you waited long? 你等了很久吗? We have been busy this afternoon. 今天下午我们一直很忙。 The temperature has stayed hot this week. 这星期天气一直很热。
