现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结在我们学习英语的过程中,时态的运用常常让人困惑,尤其是现在完成时。

今天,我们来聊聊瞬间动词和延续性动词在现在完成时中的变化。

这是一个既有趣又富有挑战的话题。

一、瞬间动词的魅力1.1 瞬间动词的定义瞬间动词,顾名思义,是那些动作一闪而过的动词,比如“见”、“吃”、“买”。

想象一下,当你看到一束花,那一瞬间你就“看见”了。

这个“看见”就是瞬间动词的典型。

它发生得很快,转眼就过去了。

比如你说,“我已经见过他了。

”这个“见”就不会有延续的感觉,更多的是一种短暂的经历。

1.2 这种动词在现在完成时的应用用现在完成时来说瞬间动词,其实是为了强调动作的结果。

比如,你可以说,“我已经吃过午餐。

”这句话的重点在于“吃”这个动作完成了,不再是“我正在吃”,因为你已经不在那个时刻了。

这种用法让我们能够轻松地传达某个经历的完成状态,而不是去细聊那个瞬间的过程。

听上去简单,却蕴藏了很多信息。

二、延续性动词的持久性2.1 延续性动词的定义延续性动词则不同,这类动词表示的是一种持续的状态或动作,比如“喜欢”、“等待”、“学习”。

当你说“我已经在学习英语”,这意味着你不仅仅是一次性的学习,而是一个持续的过程。

它带给人一种时间上的延续感。

2.2 现在完成时的特殊效果在现在完成时中,延续性动词常常强调动作的持久性。

比如,“我已经住在这里三年了。

”这句话传达的不仅是住的事实,还有那种与这个地方的连接感。

时间在这里变得重要,像是一条细线,把过去和现在连在一起。

这种用法能让对话更生动,让人更能感受到时间的流逝。

2.3 从瞬间到延续的转变有趣的是,瞬间动词在特定的上下文中也可以转变成延续性动词。

例如,“我已经见过他”变成“我已经在想他”。

这里,虽然“想”是个延续性动词,但它的来源是那一瞬间的“见”。

这样的转变让我们更能感受到人际关系的深度。

三、瞬间与延续的结合3.1 相互交织的魅力在交流中,瞬间动词和延续性动词并不是孤立的。

(完整版)现在完成时中短暂性动词变延续性动词归纳表

延续性动词与非延续性动词及其转换动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。

一.延续性动词表示能够延续的动作,如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。

延续性动词可以与表示时间段的状语连用。

表示时间段的短语有: ⑴for+一段时间, 如:for 2 years; ⑵since从句, 如since he came here; since+过去时间点名词, 如since last year, since 5 days ago。

例: He has lived here for 6 years.You can keep the book for 5 days.二.非延续性动词也称终止性动词、瞬间动词, 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等。

非延续性动词在肯定句中与表示时间点的状语连用,如:two years ago; at 5 o'clock;例:He died 5 years ago.三.延续性动词与非延续性动词之间的转换:(考试重点)例:He left five minutes ago. = He has been away for five minutes.这句话的意思是指他离开的动作是5分钟之前发生的,是过去时。

也就是说从他离开到现在已经有五分钟了,这个动作是延续的,要用现在完成时,并且要把原来的短暂性动词改为延续性动词。

一些短暂性动词及相应的延续性动词:arrive(get to /reach)→ be here (in)begin(start) → be ondie → be deadcome here(back)→be here(back)leave → be away (from)fall ill(sick, asleep)→be ill(sick, asleep)get up→ be upgo/ get out(there)→ be out(there)finish → be overput on → wear 或be onopen → be open(keep sth. open)join → be in或be a member of…+组织机构close → be closedgo to school → be a studentborrow →keepbuy/get →havecatch(a cold) → have(a cold)get to know → know begin to study → study come to work → work move to → live in finish → be over come to → be insit down → be seated marry → be married dress → be dressed become → be。

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结在现代汉语中,现在完成时是表示过去发生的动作对现在产生的影响的一种时态。

而在现在完成时中,瞬间动词和延续性动词的用法有所不同。

本文将从理论和实践两个方面,对现在完成时中瞬间动词变延续性动词进行总结。

一、现在完成时的构成现在完成时由“助动词have/has + 过去分词”构成。

例如:I have seen that movie.(我已经看过那部电影了。

)二、瞬间动词变延续性动词1. 瞬间动词变成延续性动词的方法在现在完成时中,瞬间动词变为延续性动词的方法主要是通过加上“-ing”后缀。

例如:come -> coming;go -> going;see -> seeing等。

这种变化使得原本表示瞬间动作的动词变成了表示持续性动作的动词。

2. 延续性动词的使用场合延续性动词表示的动作在时间上没有明确的结束点,通常是持续性的。

在现在完成时中,延续性动词的使用场合主要包括以下几种:(1)表示一个长时间内一直在进行的动作。

例如:I have been studying English for 5 years.(我已经学习英语5年了。

)(2)表示一个习惯性的动作或者状态。

例如:She has been playing the piano since she was a child.(她从小就一直在弹钢琴。

)(3)表示一个与现在有关联的动作或状态。

例如:He has been living in this city for 3 years.(他已经在这个城市生活了3年了。

)三、结论现在完成时中瞬间动词变延续性动词是一种常见的语法现象。

通过掌握这种现象,我们可以更好地理解和使用现在完成时这一时态。

这也有助于我们提高自己的语言表达能力,使我们的语言更加地规范和准确。

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结现在完成时中瞬间动词变延续性动词的探讨一、1.1 现在完成时的基本概念现在完成时是英语语法中的一个重要时态,它表示过去发生的动作对现在造成的影响或结果。

在现在完成时中,我们使用“have/has + 过去分词”的结构来表示动作的完成。

而瞬间动词,顾名思义,是指那些表示短暂动作的动词,如:eat、drink、run等。

将这些瞬间动词变为延续性动词,使得它们在现在完成时中能够更好地表达过去的某个时间段内持续发生的动作。

二、1.2 瞬间动词与延续性动词的区别瞬间动词和延续性动词的主要区别在于动作的持续时间。

瞬间动词表示的动作通常持续时间较短,而延续性动词则表示动作在较长时间内持续进行。

例如,我们可以说“我吃了一碗面条”(the instant I ate the noodle),但更自然的表达应该是“我已经吃了一碗面条”(I have been eating the noodle)。

这里的“eating”就是一个延续性动词,表示动作从过去某个时间开始一直持续到现在。

三、2.1 瞬间动词变成延续性动词的方法要将瞬间动词变为延续性动词,我们需要对其进行时态和语态的转换。

具体来说,有以下几种方法:1. 将瞬间动词变为进行时态。

进行时态表示动作正在进行,通常用“be + 现在分词”的结构来表示。

例如,我们可以将“eat”变为“am eating”,这样就变成了一个延续性动词。

需要注意的是,这种方法只适用于第一人称单数(I)的情况,其他人称和复数形式需要相应地调整。

2. 将瞬间动词变为被动语态。

被动语态表示主语是动作的承受者,通常用“am/is/are + 过去分词”的结构来表示。

例如,我们可以将“eat”变为“was eaten”,这样就变成了一个延续性动词。

需要注意的是,这种方法同样只适用于第一人称单数(I)的情况,其他人称和复数形式需要相应地调整。

四、2.2 瞬间动词变成延续性动词的例子下面我们通过几个例子来说明如何将瞬间动词变为延续性动词:例1:I drink coffee every morning.(我每天早上喝咖啡。

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结一、现在完成时中瞬间动词变延续性动词的概述在我们的日常生活和工作中,我们经常会遇到一些需要表达动作持续时间的情况。

这时候,我们就需要使用现在完成时来表示这个动作从过去开始一直持续到现在。

而在这个过程中,有些瞬间动词会变成延续性动词,这样可以让我们的表达更加准确和自然。

本文将对现在完成时中瞬间动词变延续性动词进行详细的理论分析和探讨。

二、现在完成时中瞬间动词变延续性动词的分类在现在完成时中,瞬间动词变延续性动词主要可以分为以下几类:1. 以“-ing”结尾的瞬间动词这类动词在变成延续性动词时,通常会在词尾加上“-e”或“-d”,然后再加上“-ing”。

例如:stop -> stopped, start -> started, eat -> eaten等。

2. 以“-e”结尾的瞬间动词这类动词在变成延续性动词时,通常会在词尾加上“-ed”,然后再加上“-ing”。

例如:come -> came, go -> gone, leave -> left等。

3. 以辅音字母+“y”结尾的瞬间动词这类动词在变成延续性动词时,通常会在词尾加上“-ied”,然后再加上“-ing”。

例如:try -> tried, stop -> stopped, care -> cared等。

4. 以元音字母+“y”结尾的瞬间动词这类动词在变成延续性动词时,通常会在词尾加上“-ied”,然后再加上“-ing”。

例如:carry -> carried, carry -> carrying, say -> said等。

三、现在完成时中瞬间动词变延续性动词的使用技巧虽然现在完成时中瞬间动词变延续性动词有很多种类,但是我们在实际使用过程中还是需要注意一些技巧:1. 要注意区分瞬间动词和延续性动词的用法。

有时候,两个词看起来很相似,但实际上它们的用法是不同的。

现在完成时中短暂性动词变延续性动词归纳表版

持续性动词与非持续性动词及其变换动词按其动作发生的方式、发生过程的长短可分为持续性动词与非持续性动词。

一.持续性动词表示能够持续的动作,如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, sta等y 。

持续性动词能够与表示时间段的状语连用。

表示时间段的短语有: ⑴for+一段时间, 如:for 2 years; ⑵since 从句, 如since he came here; since+过去时间点名词, 如since last year, since 5 days ago。

例: He has livedhere for 6 years.You can keep the book for 5 days.二.非持续性动词也称停止性动词、瞬时动词, 表示不可以持续的动作,这类动作发生后立刻结束。

如:open, die, close, begin, finish, come, go, move, borrow, lend, buy 等。

非持续性动词在一定句中与表示时间点的状语连用,如:two years ago; at 5o'clock;例:He died 5 years ago.三.持续性动词与非持续性动词之间的变换:(考试要点)例:He left five minutesago. = He has been awayfor five minutes.这句话的意思是指他走开的动作是 5 分钟以前发生的,是过去时。

也就是说从他走开到此刻已经有五分钟了,这个动作是持续的,要用此刻达成时,并且要把本来的短暂性动词改为持续性动词。

一些短暂性动词及相应的持续性动词:arrive(get to /reach)→be here (in)begin(start)→be ondie →be deadcome here(back)→be here(back)leave →be away (from)fall ill(sick, asleep) →be ill(sick, asleep)get up →be upgo/ get ou(t there)→be out(there)finish →be overput on →wear 或be onopen →be open(keep sth. open)join →be in或be a member of +⋯组织机构close →be closedgo to school→be a studentborrow →keepbuy/get →havecatch(a cold)→have(a cold)get to know k→nowbegin to study→studycome to work→workmove to →live infinish →be overcome to →be insit down →be seatedmarry →be marrieddress →be dressedbecome→be3。

新人教版英语九年级全册:完成时态瞬间动词变延续性动词规则表

完成时态瞬间动词变延续性动词规则表延续性动词与终止性动词:动词按其动作发生的方式,动作发生过程的长短,分为延续性动词和终止性动词。

延续性动词表示的动词是一种延续的动作,这种动词可以延续下去或产生持久的影响。

如:learn,work,stand,lie,know,walk,keep,have,wait,watch,sing,read,sleep,live终止性动词也称非延续性动词、瞬间动词,表示的动作不能延续,即动作发生立即结束,产生某种结果。

在有了某种结果之后,就不能再继续下去。

如:leave,start,set out,arrive,reach,get to,begin, stop,shut,turn off,marry,put,put on,get up,wake,fall,join,receive,finish,end,complete,become,come,go,die,close,open,break,give, jump,buy,borrow等。

1.终止性动词的用法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。

如: 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(只限于肯定式)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.将短暂性动词改为相应的延续性动词或短语和一段时间连用,其常用的方法有如下几种:a.用相应的延续性动词替换的主要有:buy→have,borrow→ keep,come /go /become→be,catch /get a cold→have a cold,get to know→know等。

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结现在完成时(Present Perfect Tense)是英语语法中的一种时态,用来表示过去发生的动作或者状态与现在的关系。

在现在完成时中,瞬间动词(Instantaneous Verbs)可以变成延续性动词(Continuative Verbs),从而改变其表达的意义和使用方式。

本文将对现在完成时中瞬间动词变延续性动词的规则进行总结和归纳,以帮助读者更好地理解和运用。

一、瞬间动词(Instantaneous Verbs)瞬间动词是指表达一种在短时间内完成的动作或者状态的动词。

这类动词通常表示瞬间、短暂的行为或事件,其行为发生的时间很快,没有持续性。

以下是一些常见的瞬间动词:1. get(得到)2. arrive(到达)3. come(来)4. open(打开)5. close(关闭)6. finish(结束)7. start(开始)8. buy(购买)9. sell(出售)10. win(赢得)等等。

二、瞬间动词变延续性动词的规则现在完成时中,瞬间动词可以通过一些规则变成延续性动词,从而具有持续性。

一般而言,瞬间动词变延续性动词的方式有两种:添加辅助动词"have been"或使用"for"或"sice"引导的时间状语从句。

1. 添加辅助动词"have been"瞬间动词可以通过在其前面添加"have been"来表示一个动作或状态的持续性。

这种形式常常用于描述一个从过去某个时间开始一直延续到现在的动作或状态。

例如:- I have been living in this city for three years.(我在这个城市生活已经三年了。

)- He has been working on this project all day.(他从早到晚一直在做这个项目。

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结现在完成时中瞬间动词变延续性动词的总结一、1.1 现在完成时的基本概念现在完成时是英语中的一种时态,它表示从过去某个时间点开始一直持续到现在的动作或状态。

在现在完成时中,我们使用助动词“have/has”加上过去分词来构成。

例如,“I have eaten breakfast.”(我已经吃了早餐。

)二、1.2 瞬间动词与现在完成时的转换瞬间动词是指那些表示一次性动作的动词,例如:eat(吃)、drink(喝)、sleep(睡)等。

这些动词在现在完成时中不能直接使用,需要将其变为延续性动词。

延续性动词是指那些可以表示持续一段时间的动作或状态的动词,例如:work(工作)、study(学习)等。

要将瞬间动词变为延续性动词,我们需要找到一个合适的词语来替换原动词,以表示动作的持续性。

例如,将“eat”变为“have been eating”,将“drink”变为“have been drinking”。

三、2.1 瞬间动词与现在完成时的转换方法在将瞬间动词变为延续性动词时,我们需要注意以下几点:1. 使用助动词“have/has”加上过去分词的形式。

2. 在过去分词前加上“been”。

3. 根据需要添加适当的副词,如“already”、“just”、“yet”等。

例如,“eat”变为“have been eating”的过程如下:确定主语和助动词。

然后,在谓语动词后加上“been”。

根据需要添加副词。

四、2.2 延续性动词的例子及其用法下面是一些常见的延续性动词及其用法:1. work:我已经开始工作了(I have already started working.);2. study:我正在学习汉语(I am studying Chinese.);3. play:他刚刚玩了一会儿(He has just played for a while.);4. read:她一直在读这本书(She has been reading this book all day.);5. sleep:他们已经睡了一整晚(They have slept all night.)。

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结

现在完成时中瞬间动词变延续性动词总结现在完成时中瞬间动词变延续性动词的总结一、1.1 现在完成时的概念与用法在英语语法中,现在完成时是一种表示过去发生的动作对现在产生影响的状态。

它由“have/has + 过去分词”构成,用来描述从过去某个时间点开始一直持续到现在的动作或状态。

现在完成时通常用于以下几种情况:1. 强调过去的行动对现在造成的影响。

2. 表示过去的经历或经验对现在的影响。

3. 表示过去的习惯或经常性动作对现在的影响。

4. 表示过去的事情一直持续到现在。

二、1.2 瞬间动词的特点与现在完成时的转变瞬间动词是指表示一次性动作的动词,如open、close、start、stop等。

这类动词在现在完成时中的使用有一定的特殊性,因为它们不能直接与have/has连用,而需要通过助动词do来构成否定式和疑问式。

例如:I opened the door.(我打开了门。

)→ I haven't opened the door.(我还没打开门。

)→ Have you opened the door?(你打开门了吗?)She closed the window.(她关上了窗户。

)→ She hasn't closed the window.(她还没关上窗户。

)→ Has she closed the window?(她关上窗户了吗?)三、2.1 现在完成时中瞬间动词的使用技巧在使用现在完成时表示瞬间动词的动作时,需要注意以下几点:1. 确保句子的时态一致。

2. 注意助动词do的使用。

3. 根据上下文判断是否需要使用完成进行时。

下面我们通过一些例子来进一步说明这些技巧的应用:1. 肯定句:I have seen that movie before.(我以前看过那部电影。

)→ I haven't seen that movie recently.(我最近没看过那部电影。

)→ Have you seen that movie?(你看过那部电影吗?)2. 否定句:She didn't finish her homework last night.(她昨晚没完成作业。

现在完成时之瞬间动词转变为持续性动词
(1)专题讲解:
在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语(for, since, how long等)连用,此时须将该瞬间动词改为延续性动词或状态动词.
Eg:
buy ( bought ) --- have / has had 买
borrow (borrowed) --- have / has kept 借
die ( died ) --- have / has been dead 死
