如题所述
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。如：stay, live, learn, study, work, wait, watch, sing, read等。
短暂性动词也称非延续性动词、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, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow, buy, die等。
现在完成时常跟表示一段时间的时间状语，如“for +一段时间”、“since +时间点”、“during the past+一段时间 ”等，因此谓语必须是一种状态或表示延续性的动作，具体来说，它必须是延续性动词及其短语、短暂性动词及其短语的否定式，或表示状态的词或短语。

一、延续性动词和终止性动词的概念
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终止性动词。
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。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。
终止性动词也称非延续性动词、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open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。
二、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.追问
时间段和时间点区别？
追答时间点是一个固定的时间,如8：00,一段时间是从某一个时间点到另一个时间点
再具体点就是时间点指具体的时间,
就在那个时间上发生了事件
比如：五天前five days ago
具体时间七点sevev o'clock
时间段指一段时间,发生的动作是持续的如：
三年以来for three years或since three years ago
简单的说`就是时间点是at 比如说at ten o'clock
时间段是in 比如说in the past ten days
转不过弯
跟时态有什么联系？
那for和since？？
追答我能不能说你……
在现在完成时的句子中,since后面接过去的某一具体时间点,“since+过去的时间点”表示从这一时间点到现在的一段时间.
这一时间点如果用时间状语从句来表示,这一从句的谓语要用短暂性动词,并且要用一般过去时.
如：
I have seen a lot of friendly people since 1980/since I came to China/ since10 months ago/since I moved to the city in 2006.
for直接接一段时间.如：
I've been in China for 5 years/for 8 weeks/for a long time.
例子是最好的解释
慢慢消化吧……
不耻下问是不错，但得完全吸收后再问另外一个问题！
追问since翻译什么意思
？

追问为什么要转
追答你是……？？
又出现了一个为什么要转？？
请评价
追问我说他们两个之间的转换
追答评价了再说
你自己看看……几天了，多少个问题了
追问耿直点
采了行了吧！。
追答你要是采纳别人，我无话可说，可你……所以不得不让人猜忌
定义：
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,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。此类动词常见的如open, close, finish, begin,buy等。
区别：
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接时间点或从句, how long等。如：
He has lived here for 6 years.他在这儿已住了六年了。
非延续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。
