1. 关于句子的延续性与非延续的问题
这里面的 she was eight years old. 指的是一个点时间。
短暂性动词 如: begin,start, finish,end, arrive, come ,go, die, 等等 指的都是一瞬间的事情,所以被称为非延续性动词
延续性动词: live,run,stay,clean,play,hold,watch,teach,read,study,teach,eat,drink,write,dance, sing,smoke
如果想表达一个延续性动作,可以采取用一个词或词组来代替终止性动词~
代替终止性动词的方法
a)用延续性动词代替终止性动词

3. 怎样将短暂性动词的句子转换为延续性动词句子
现在完成时是中学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。
下面对其概念进行详细分析: 延续性动词的用法特征 1.延续性动词可以用于现在完成时,其完成时态可与表示"段时间"的状语连用。表示"段时间"的短语有:for two years, during the past three years, since last year, how long等。
如:I have learned English since I came here.自从我来到这儿就学英语了。 2.延续性动词不能与表示短暂时间的"点时间"状语连用。
如:It raind at eight yesterday morning.(误) 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等终止性动词来表示。
上句可改为:It began to rain at eight yesterday morning.(正)又如: -When did you get to know Jack? -Two years ago. -Then you've known each other for more than two years. -That's right. 5、终止性动词的用法特征 1.终止性动词可用来表示某一动作完成,因此可用于现在完成时。如: The train has arrived.火车到了。
Have you joined the computer group? 你加入电脑小组了吗? 2.终止性动词表示的动作极其短暂,不能持续。因此,不可与表示一段时间的状语连用(只限肯定式)。
如: (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。
下面列举几例:leave→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold。go to-been to/gone to/been in ,come/arrive/get/reach/move---be in/at ,put on ----wear,end/finish-----be over。
(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。
4. 现在完成时态的标志性的词语有哪些
yet already in the last five/few years for + 一段时间 since every never up to/till now so far Up to the present once recently lately 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 lost my wallet.(含义是:现在我没有钱花了.) Jane has laid the table.(含义是:已可以吃饭了.) 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,持续到现在的情况,常与for,since连用.Mary has been ill for three days.I have lived here since 1998.3.现在完成时往往同表示不确定的过去时间状语连用,如already,yet,just,before,recently,lately等:He has already obtained a scholarship.We have seen that film before.Have they found the missing child yet 4.现在完成时常常与表示频度的时间状语连用,如often,sometimes,twice,on several occasion等:Have you ever been to Beijing George has met that gentleman on several occasions.5.现在完成时还往往可以同包括现在时间在内的时间状语连用,如now,up to these few days/weeks/months/years,this morning/week/month/year,now,just,today,.6.现在完成时表示现在之前业已完成的动作,虽然其效果或影响仍然存在但已不再继续,但是有一些现在完成时的句子,在后面加上for+一段时间,则现在完成时的动作就表示延续性.Thomas has studied Russian.(现在不再学俄语) Thomas has studied Russian for three years.(=Thomas began to study Russian three years ago,and is still studying it now.(同第2点用法第一个例句) 7.现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作.We have had four texts this semester.例如:He has turned off the light.他已把灯关了.(动作结束于过去,但说明的是现在的情况--灯现在不亮了.) 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,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.例如:Have you found your pen yet?你已找到你的钢笔了吗?例如:He has lived here since 1978.自从1978年以来,他一直住在这儿.(动作起始于1978年,一直住到现在,可能还要继续住下去.) I have been in the army for more than 5 years.我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.) 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 例如:I have heard nothing from him up to now.到目前为止我没有他的任何消息.注意:(1)现在完成时的未完成用法只适用于延续性动词,不可用于终止性动词,即瞬间完成或延续时间很短的动词.如:come,go,arrive,leave,join,become,die等.。
5. 关于come的延续行动词
我是英语老师,帮帮你。
在英语中,并不是说非延续性动词不能用于现在完成时,而是说,如果某个句子中有延续性时间,就不能用非延续性动词,除非把这个动词转化成延续性动词。
例:他去世五年了。
He died five years ago.
He has been dead for five years.
He has been dead since five years ago.
It has been five years since he died.
就你提出的这个句子而言,因为它没有特定的延续性时间,当然就不用把come改成延续性了。
祝你进步!
6. 常见的延续性动词(短语)有哪些
参考答案: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。
延续性动词可以与表示时间段的状语连用。
表示时间段的短语有:for+ 时间,for 2 years; since从句,since he came here; since+时间点名词,since last year, since 5 days ago; how long; for a long time等。
例: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?
