延续性动词和短暂性动词的区别及用法
短暂动词当然可以用于进行时态。用什么时态和它是不是短暂动词没有什么关系。英语动词中，有些动词只用为表示状态；但有些动词，有时表示状态，有时又表示动作，遇到这样的动词，就要先分清它是作了状态动词呢，还是作了动作动词。如果是作了状态动词，就不用于进行体。 1、系动词表示状态，是状态动词，不用于进行体。 It is the Mid-autumn Festival today. --Let’s go to the suburbs to enjoy the moon. --It sounds a nice idea. Cui Yongyuan looks good-humoured. be动词也有用于进行体的时候。 2、感觉动词表示状态，是状态动词，不用于进行体。 They saw the plane splashing on the top of the hill. The medicine tastes a little bitter. Don’t you hear me? I’m saying. 常见的还有：feel, keep, notice, smell, etc. 如果表示强调、短暂、一时的状态，也可以用于进行体： The weather is keeping fine these days. I didn’t expect he is being terribly friendly to me. My back is hurting. 3、表示思想活动的动词也是状态动词，不用于进行体。 I know nothing about the market for the festival. I wonder why they have made a decision to go on with the work during the festival. What do you mean? 常见的还有：Admit, agree, appreciate, believe, care, consider, dislike, disbelieve, doubt, expect, find (=consider), forget, guess, imagine, realize, regret, remember, see (understand), suppose, think etc. 如果表示说话人的情感，也会用于进行体： --I am loving the Beijing Opera, aren’t you? --No. Frankly, I am hating it. 4、动词表示愿望、需要时也是一种状态，不用于进行体。 I hope we can have 7 days off over the festival. We all desire health and happiness. What you said requires careful thought. 常见的还有：need, want, wish etc. 5、存在与所属也是一种状态，表示存在与所属的动词也被看作是状态动词，不用于进行体。 He owed his success to luck more than to capacity. The two sides have reached a partial agreement, but several differences still exist between them. 常见的还有：belong to, compare, concern, consist of, depend on, equal, have, include, involve, keep, own, possess, result, stand for etc. 动词have表示所属，但更多的情形是构成短语表示动作，这时，它就可以用于进行体了： He has a good memory. (have在此例中表示possess, owe拥有，是状态)
现在完成时延续性与暂短性动词用法
现在完成时（短暂性动词与延续性动词）的用法 基本结构：主语+have/has+过去分词(done) ①肯定句：主语+have/has+过去分词+其他 ②否定句：主语+have/has+not+过去分词+其他 ③一般疑问句：Have/Has+主语+过去分词+其他 ④特殊疑问句：特殊疑问词+一般疑问句（have/has+主语+过去分词+其他） （1）现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在. I have spent all of my money.(含义是:现在我没有钱花了.) Jane has laid the table.(含义是:现在桌子已经摆好了.) Michael has been ill.(含义是:现在仍然很虚弱) He has returned from abroad. (含义是:现在已在此地) （2）现在完成时可以用来表示发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示）常与for（+时间段）,since（+时间点或过去时的句子）连用. Mary has been ill for three days. I have lived here since 1998. 注（超重要）：瞬间动词（buy,die,join,lose……）不能直接与for since 连用。要改变动词come-be go out-be out finish-be over open-be open die-be dead 1.have代替buy My brother has had(不能用has bought) this bike for almost four years. 2、用keep或have代替borrow I have kept(不能用have borrowed) the book for quite a few days. 3、用be替代become How long has your sister been a teacher? 4、用have a cold代替catch a cold Tom has had a cold since the day before yesterday. 5、用wear代替put on
瞬间性动词与延续性动词(新)
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：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: 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+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,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。 如果要与for+ 时间段，since+年份，since+时间段+ago，how long连用时，瞬间性动词要变延续性动词。 三.延续性动词与非延续性动词之间的转换：
例：（1）他死了三年了。 误：He has died for three years. 正：He has been dead for three years. 正：He died three years ago. 正：It is three years since he died. 正：Three years has passed since he died. (2) 他来这儿五天了。 误：He has come here for five days. 正：He has been here for five days. 正：He came here five days ago. 正：It is five days since he came here. 正：Five days has passed since he came here. (1)、(2)句中的die、come为终止性动词，不能与表示"段时间"的状语连用。那么，应如何正确表达呢？可以采用下面的四种方法： (1)将句中终止性动词转换为相应的延续性动词, 如上面两例中的第一种正确表达方式. (2)将句中表示"段时间"的状语改为表示过去确定时间的状语，如下面两例中的第二种正确表达 方式。 (3)用句型"It is+段时间+since..."表达原意，如上面两例中的第三种正确表达方式。 (4)用句型"时间+has passed+since..."表达原意，如上面两例中的第四种正确表达方式。 四、终止性动词可用于现在完成时否定式中，成为可以延续的状态，因而可与表示一段时间的 状语连用。 如:1.He hasn't left here since 1986. 2.I haven't heard from my father for two weeks. 五、终止性动词的否定式与until/till连用，构成"not+终止性动词+until/till ..."的句型，意为"
初中一般现在时与三单动词的变化规则
一般现在时 1.概念：经常、反复发生的动作或行为及现在的某种状况。 2.时间状语：always,usually,often,sometimes,every week(day,year,month…),once a week, on Sundays, 3.基本结构：动词原形/第三人称单数形式（如主语为第三人称单数，动词上要改为第三人称单数形式） 4.否定形式：am/is/are+not; 谓语动词若为动词，则在其前加don't,如主语为第三人称单数，则用doesn't，同时还原行为动词。 5.一般疑问句：把be动词放于句首；用助动词do提问，如主语为第三人称单数，则用does，同时，还原行为动词。 三单动词的变化规则 1．一般情况下，直接加-s 如：play—plays， want—wants， work—works， know—knows， help —helps，get—gets 2．以s. x. sh. ch. o结尾，加-es 如：guess—guesses， fix—fixes， teach—teaches， brush—brushes， go —goes，do—does，watch—watches，catch—catches 3．以“辅音字母+y”结尾，变y为i, 再加-es 如：study—studies，carry—carries，fly—flies，worry—worries 一般现在时用法专练: 一、写出下列动词的第三人称单数
drink ________ go _______ stay ________ make ________ look _________ have_______ pass_______ carry ____ come________ watch______ plant_______ fly ________ study_______ brush________ do_________ teach_______ catch _________ wash_________ like________have______ say_________ learn ________ eat________ read_________ sing_______ 二、用括号内动词的适当形式填空。 （一） 1.

现在完成时中短暂性动词变延续性动词归纳表精编版
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 on die → be dead come here（back）→be here（back） leave → be away (from) fall ill(sick, asleep)→be ill(sick, asleep) get up→ be up go/ get out（there）→ be out（there） finish → be over put on → wear 或be on open → be open（keep sth. open） join → be in或be a member of…+组织机构 close → be closed go to school → be a student borrow →keep buy/get →have catch(a cold) → have(a cold)
瞬间动词与延续性动词
瞬间动词与延续性动词 “瞬间动词”又叫终止性动词、点动词，表示动作有一个终点，到了终点就不能再延续。因此在现在完成时的句子中，瞬间动词不能直接与for/since 连用，需要转换成“延续性动词”。常用的请见5BP17表格。 Exercises 一、改错：横线划出错误的部分，并在后面的横线上改正。 1. How long have you begun to study English? ________________________ 2. I have borrowed this book for two weeks. ________________________ 3. The river has become very dirty since last August.___________________ 4. Our manager is away today. He has been to Guangzhou on business. ___________________________ 5.

延续性动词和短暂性动词转换归纳
延续性动词和短暂性动词转换归纳 瞬间动词可以用于现在完成时，但不能和表示一段时间的状语连用如:for 和since 所引导的时间状语都表示一段时间.那就要将瞬间动词转化为表延续的动词或者表状态的be+名词／形容词或副词／介词短语等。 leave—been away from buy—have borrow—keep die—be dead get up—be up put on—be on / wear come / get back—be back go to town—be in town lose—be missing catch a cold—have a cold close—be closed / not open open —be open fall ill / asleep— be ill / asleep begin /start—be on return--be back marry---be married finish--be over become--be come / go to —be in / at arrive in （at）/ get to / reach——be in / at join + 名词-------be in + 组织/ be a（an）+组织成员get /receive a letter from—have a letter from
一看时间状语。如果句中没有表示过去确切时间的状语，常用现在完成时；如果有，则只能用一般过去时。如： I have visited the factory. I visited the factory last year. 二看句首有无疑问词。如果笼统地问人家做过某事了吗（句首无疑问词），常用现在完成时；但进一步询问何时、何地、何原因、用什么方式做那事时（句首有疑问词）就要用一般过去时。如：－Have you had your breakfast? －Yes, I have. －When did you have it? －At seven thirty. 注意：这种用法是以连贯性问答为背景的。否则就需要具体情况具体分析。如： How many words have you learned by heart? How did you learn them by heart? 三看句中谓语动词是否为延续性动词。如果表示的动作或状态一直延续到现在，最好选用延续性动词，并使用现在完成时；如果是瞬间动词，则用一般过去时。如： He has been a league member for two months. He joined the Youth League two months ago.

现在完成时中非延续性动词的转换 现在完成时是初中英语语法的重点之一。它表示过去发生的某一动作或存在的状态，一直持续到现在，并可以和以for或since引导的表示一段时间的状语连用，也可以用在以“how long”提问的句子中，句子中的谓语动词一般为延续性动词。但是，有些动词所表示的动作是短暂的，这类动词叫做非延续性动词。如：come, go, reach, arrive, leave, borrow, buy, join, die, begin, start, finish等。在现在完成时的句子中，非延续性动词作谓 语动词时，不能和表示一段时间的状语连用。 同学们在使用这两类动词作谓语动词时，常会出现错误。例如： （误）Tom has bought the book for a week. （正）Tom has had the book for a week. （误）My father had joined the Party for ten years. （正）My father has been in the Party for ten years. 如果要表示动作的连续性，就要把非延续性动词转换成相应的延续性动词或短语，具体转换如下： come/go/reach/arrive→be in/at, leave→be away from, borrow→keep, buy→have, join→be in/be a member of, die→be dead, start/begin→be on, finish/end→be over, open→be open (adj.), close→be closed (adj.), marry→be married 注意： 1. 非延续性动词可以在现在完成时的否定句中作谓语，并可以与for，since引导的时间状语连用，表示动作的延续过程。例如： She hasn’t bought any new clothes since last year. 2. 在现在完成时的肯定句中，非延续性动词作谓语时不能与for，since引导的表示一段时间的状语连用，但可以用其他句式来表示同一个意思。例如： He has been away from Beijing for two years. = He left Beijing two years ago. = It is two years since he left Beijing. = Two years has passed since he left Beijing. 练习：用现在完成时改写下列句子，使A，B两句意思基本一致。每空限填一词。 1. A. They came to our school in 1980. B. They ____ ____ ____ our school since 1980. 2. A. The man died five years ago. B. The man ____ ____ ____ for five years. 3. A. The meeting began two minutes ago. B. The meeting ____ ____ ____ for two minutes. 4. A. We borrowed two books last week.
