延续性动词和非延续性动词的转换（方法）
思考这个动作是否能延续，是否能持续一段时间，还是只能发生在一瞬间。表现形式就是这个动词相关的时间状语。比如，die。他5天前死了 He died 5 days ago. “死”不能一直死来死去的。ago是表示多久前的那个时间点。而睡觉，他睡了5天，就是延续性。He has slept for 5days. for就是延续了5天。
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。

时态是英语谓语动词的一种形式，表示动作发生的时间和所处的状态.英语中的时态是通过动词形式本身的变化来实现的。中学阶段较常用的有十种：一般现在时,一般过去时,一般将来时,过去将来时,现在进行时，过去进行时，将来进行时,过去完成时，现在完成时和现 在完成进行时、
时态一致
1） 如果从句所叙述的为真理或不变的事实，则永远用现在时。
At that time,people did not know that the earth moves.
He told me last week that he is eighteen.
2）宾语从句中的助动词ought,need,must,dare 时态是不变的。
He thought that I need not tell you the truth.

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:for+一段时间,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?
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.
否定的终止性动词可以与表示时间段的时间状语连用。例:I haven't left here for 3 years. I haven't heard from him for 3 weeks.
三.延续性动词与非延续性动词之间的转换：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。 例:The old man died 4 years ago. ----The old man has been dead for 4 years. ---- It is 4 years since the old man died. ----Four years has passed since the old man died. He joined the Party 2 years ago. -----He has been in the Party for 2 years. I bought the book 5 days ago. ---- I have had the book for 5 days.
