延续性动词和非延续性动词
延续性动词与非延续性动词
延续性动词与非延续性动词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：study, 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。
延续性动词的用法很广，常见于现在完成时中的句子中，且常与for，how，long，since等引导的表示一段时间的状语或状语从句连用。
表示时间段的短语有:1.for+一段时间, eg: for 2 years; for a long time等2.since从句,since he came here;3.since+时间点名词+ago, eg：since last year, since 5 days ago;4. how long;二.非延续性动词也称终止性动词、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, move, happen, marry, arrive/reach, post, fall, break, lose, give, join, receive, hear, hear from, become 等。
终止性动词又叫瞬间动词或点动词，瞬间动词的肯定句在一般情况下，不能与表示一段时间的状语或疑问词连用。
但是在否定句中，瞬间动词也可以和表示一段时间的状语、连词连用，它的含义是好长时间没进行这个动作了，没进行此动作的状态就可以延续。
可用于现在完成时态，但由于动作是瞬时间完成的所以不能与for或since引出的时间状语连用。
英语中常见的非延续性动词在完成时态中可改为相应的表示延续性的动词或短语，这时可与表示一段时间的的状语连用。
延续性动词及非延续性动词
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, stay等。
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 :for+一段时间 ,如：for 2 years，for a long time; since 从句 , 如： since he came here; since+时间点名词 , 如： since last year, since 5 days ago; how long等。
请看例句has lived here for 6 years.请看例句can keep the book for 5 days.请看例句stayed there for 2 weeks last year.请看例句long did you stay there last year请看例句brother has joined the army for two years ．（误）My brother has been a soldier for two years .（正）我哥哥自 1999 年就从军了。
请看例句brother has joined the army since 1999．（误）My brother has been a soldier since 1999(正)你哥哥从军多久了请看例句long has your brother joined the army （误）How long has your brother been a soldier（正）二.非持续性动词也称停止性动词、瞬时动词或点动词 ,表示不可以持续的动作 ,这类动作发生后立刻结束。

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 5o'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: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。
下面是一些短暂性动词及相应的延续性动词,须牢记。
leave --- be away, borrow --- keep, buy --- have,begin/start --- be on, die --- be dead, finish --- be over,join --- be in+组织机构 , be a member of+组织机构 ,open sth --- keep sth open, fall ill --- be ill, get up---be up,catch a cold --- have a cold, come here --- be here,go there --- be there, become --- be, come back --- be back,fall asleep --- be asleep, get to/ arrive/reach --- be (in,leave --- be away from, get to know --- know,go (get out → be out, put on→ wear ; catch a cold → have a cold等。
延续性动词与非延续性动词
延续性动词与非延续性动词一、延续性动词和非延续性动词的概念英语中，动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和非延续性动词。
延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。
此类动词常见的如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay 等。
非延续性动词也称终止性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束。

如：He has lived here for 6 years.他在这儿已住了六年了。
I have learned English since I came here.自从我来到这儿就学英语了。
2. 延续性动词不能与“点时间”状语连用。
试比较：误：It rained at eight yesterday morning.正：It began to rain at eight yesterday morning.析：rain为延续性动词，而at eight表示“点时间”，前后显然矛盾。
如果用延续性动词表示一瞬间的动作，可以借助come, begin, get等非延续性动词来表示。
又如：--When did you get to know Jack?你什么时候认识杰克的？--Two years ago.两年前。

延续性动词和非延续性动词
延续性动词和非延续性动词延续性动词和非延续性动词是英语语法中的两个重要概念。
它们在句子中的使用方式不同，对句子的意思和结构有着重要影响。
本文将介绍延续性动词和非延续性动词的定义、区别以及使用方法。
延续性动词（Stative Verbs）是指表示状态、感受或想法等不能持续一段时间的动词。
延续性动词通常用于表达事物的本质、性质或状态，它们不涉及到动作或变化。
常见的延续性动词有：be（是/存在）、belong（属于）、consist（由...组成）、know（知道）、like（喜欢）等。
与延续性动词相对应的是非延续性动词（Dynamic Verbs），也称为行为动词。
它们表示某种行为或动作，可以持续一段时间。
非延续性动词强调的是动作的完成过程，而非动作的结果或状态。
常见的非延续性动词有：run（跑）、eat（吃）、write（写）、drive （驾驶）等。
延续性动词和非延续性动词在句子中的使用方式有所不同。
延续性动词通常用于现在进行时态中，表示正在进行的动作或状态。
例如：I am reading a book.（我正在看书。
）这里的reading是延续性动词，表示正在进行的动作。
非延续性动词则不常用于现在进行时态，因为它们强调的是短暂的动作或完成的事件。
例如：I am writing a letter.（我正在写信。
）这里的writing是非延续性动词，表示正在进行的动作。
另一个区别是，延续性动词通常不用于进行时态以外的其他时态，而非延续性动词可以用于各种时态。
例如，延续性动词like一般只用于现在时态，如I like ice cream.（我喜欢冰淇淋。
）而非延续性动词eat可以用于各种时态，比如I ate breakfast this morning.（我今天早上吃了早餐。
）此外，在使用一些动词时，弄清楚它们是延续性动词还是非延续性动词对于正确理解句子的意思也十分重要。
例如，动词have可以是延续性动词，表示拥有或持有某物，也可以是非延续性动词，表示吃或喝某物。
延续性和非延续性动词
按动作发生的方式，发生过程的长短，可把动词分为延续性动词和非延续性动词。
延续性动词：learn, work, stand,lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等，可与一段时间连用，如：for 2 years, sincehe came here, sincelast year.非延续性动词：open, close, die, begin, start, finish, come, go, borrow, lend, buy等，不能与一段时间连用。
但其否定式可以与一段时间连用。

一．延续性动词和非延续性动词：㈠延续性动词：表示一种可以持续的行为过程或状态。
drink喝have有talk说know 知道stand站立sleep睡觉sing唱歌wait等wear穿walk走work工作rain下雨keep保持snow 下雪eat 吃read读play玩live 居住smoke 抽烟lie躺着stay保持㈡终止性动词：（非延续性动词），表示行为或者动作是短暂瞬间完成的。
come来fall倒borrow借admit承认break打破start开始join加入buy买jump跳lose丢open打开close关stop结束begin开始go走put放die死hit击中leave离开arrive到达marry结婚㈢两者的用法和区别：1.延续性动词可以用表示一段时间的状语修饰，非延续动词不可用。
How long can I keep the book.这本书我可以借多久？They will work here till next Friday.她们要在这里工作到下周五。
2.有时，非延续性动词也可以与表示一段时间的时间状语搭配，但这种表示一段时间的状语,实质上是表示一段时间内的某个时间“点”。
The play will start in half an hour.这出戏半个小时后开始。
The fire broke out during the night.火是夜间发生的。
3.非延续性动词一般不用于while引导的时间状语从句中。
While I came home, he was cooking dinner. (错)When I came home, he was cooking dinner. (对)4.用延续性动词表示一时的动作，可以在该动词前加get/begin/come.When did you get to know him?你什么时候认识他的？They begin to see that they had made a serious mistake.她们开始认识到自己犯了一个大错。
5.非延续性动词的否定式表示动作的否定，此时可与表示一段时间的状语搭配。
We did not find our seats till the play had begin.我们直到戏开始时才找到位子。
We have not come here for ages.我们多年没来这里了、The rain has not stopped since three hours ago.这雨已经下了三个小时了。
二：一般过去时和过去进行时的区分：㈠一般过去时：①概念：过去某个时间里发生的动作或者状态；过去经常，反复发生的动作。
②时间状语：一段时间+ago, yesterday, the day before yesterday, last week, last(year, night, month…), in 1989, just now, at the age of 5, one day, once upon a time, the other day(前几天），at that time(当时)，etc.③基本结构：主语+动词过去式+其他④用法：Ⅰ.表示发生在过去的动作或存在的状态。
例如：My uncle mended my washing machine last Sunday afternoon.I was out of town at the time, so I don’t know exactly how it .A. was happeningB.. happenedC. happensD. has happenedⅡ.表示过去经常发生或反复发生的动作或存在的状态。
例如：When I lived in the countryside, I swam in the river with my friends onSaturdays.— You speak very good French!— Thanks. I French in Sichuan University for four years.A..studiedB. studyC. was studyingD. had studied㈡过去进行时：①概念：表示过去某段时间或某一时刻正在发生或进行的行为或动作。
②时间状语：at this time yesterday, then(那时)，last night(昨晚)，at five yesterday(在昨天五点)，the whole morning(整个上午)，at that time 或以when引导的谓语动词是一般过去时的时间状语，具体的时间+过去的时间状语（at ten o'clock yesterday morning）等。
例：When he came in, I was reading a newspaper.（他进来时我正在读报纸。
）③基本结构主语+was/were+动词的现在分词+其他④用法：Ⅰ.表示过去某时正在进行的动作。
过去进行时的这一用法，通常要把时间状语体现出来，或者通过上下文把时间关系暗示出来。
例如：What were you doing at 7:00 p.m. yesterday?When I went downstairs, they were eating breakfast.补给站：基于过去进行时的这一用法，可以用它来描述事件发生的背景。
例如：The sun was shining, the wind was blowing, and a group of soldiers were marching.I called Hannah many times yesterday evening, but I couldn’t get through. Her brotheron the phone all the time!A.. was talkingB. has been talkingC. has talkedD. talkedⅡ.表示过去某种习惯性动作。
过去进行时的这一用法，通常是指过去某一阶段暂时性的习惯性动作。
例如：Tom was getting up at five every day that week.Ⅲ.表示过去将来，多用于go, come, leave, start, take off等动词。
例如：The winter holiday was drawing near, but nobody knew where they were going for the holiday.㈢二者区分：①强调点不同：一般过去时侧重说明某动作发生的事实；过去进行时侧重强调某动作的持续过程或动作持续的长短。
It rained cats and dogs last night.(强调下过雨，并不强调持续多长时间。
)昨晚雨下得真大。
It was raining cats and dogs last night.(强调没停，一直持续。
)昨晚整整一夜都在下大雨。
②动作的完成情况不同过去进行时往往表示动作的未完成性还在进行，而一般过去时往往表示动作已完成：David wrote a letter to his father last night．大卫昨晚给他父亲写了一封信。
(信写完了。
)David was writing a letter to his father last night．大卫昨晚正在给他父亲写信。
(指信在写的过程中，不一定写完。
)Alice read a science fiction last night.(很可能已经读完了。
）Alice was reading a science fiction at 8 last night.(当时正在进行的动作)③持续的情况不同：一般过去时可以表示时断时续的动作，而过去进行时只能表示持续不间断的动作。
I sometimes walked to school to avoid the heavy traffic.我有时步行去上学为了避开拥挤的交通。
He was working from 4 until suppertime.他从4点一直工作到晚饭时间。
④所起的作用不同：一般过去时和过去进行时在句中可同时出现，前者表示短暂的某一动作，后者为前者提供背景，起铺垫作用。
When you phoned I was talking with my foreign teacher.你们打电话来时，我在和我的外籍教师聊天。
⑤当二者同时出现在句中时，通常是表示持续时间较短的动作用一般过去时，表示持续时间较长的动作用过去进行时。
例如：I broke a glass while I was cooking the dinner.The pupils were talking noisily when the teacher stepped in.What were you doing when the fire burst out from the second floor?二楼起火时你在干什么？I was writing while she was reading.我写字，她读书。
⑥过去进行时和always连用，表示赞扬、感叹、厌恶等感情色彩；而一般过去时和always连用,表示经常或反复发生的动作。
试比较：He was always changing his mind．他总是三心二意。
(表示厌恶)He always went to work by bus last year．去年他总是乘坐公共汽车上班。
(表示经常性动作)⑦一般说来，过去进行时侧重动作持续时间的长度；而一般过去时只说明过去某时发生某事，侧重说明事实。
试比较：It was raining heavily last night．昨晚下着大雨。
(侧重说明下雨持续的时间长。
)It rained heavily last night．昨天下了大雨。
(侧重说明下雨这一事实。
)⑧在带有a ll night, the whole morning等强调时间长度的状语时，句中谓语动词用过去进行时更好些。
如：He was working all night last Monday．上周一他整整工作了一个晚上。
⑧在when引导的时间状语从句中，当when相当于while时，用一般过去时与过去进行时差异不大。
如：I saw John when I walked／was walking to the station．我步行去火车站时看见了约翰。
