英语动词根据词义可分为两种，一种是延续性的，一种是终止性的，终止性动词(也可称为非延续性动词、瞬间动词、或点动词)，如begin, start, die, buy, leave, come等，表示动作的发生与结束于一瞬间完成，不能再延续，所以它的现在完成时不能和表示延续的时间状语连用，即不能与表示一段时间的状语，for+时间段, since+时间点/从句连用，也不能用在how long引导的特殊疑问句中。

•eg. I've left Shanghai for three days.(×)
•I've been away from Shanghai for three days.(√).
•I left Shanghai three days ago. (√)
•It is /has been three days since I left Shanghai.(√)
•终止性动词要表示持续时，可用以下方法：
⑴将时间状语改为时间段+ ago，句中谓语动词用一般过去时。

•eg. My brother joined the army two years ago. 我弟弟参军两年了。

⑵若保留for+时间段，since+时间点/从句，或用在how long句型中，则需将终止性动词改为相应的状态动词或延续性动词。

•常见终止性动词与延续性动词(或状态动词)的对应关系如下：
•open-----be open die------be dead close----be closed become---be
•borrow---keep begin/start-----be on put on----wear
•leave-----be away (from) buy-----have sleep /fall asleep----be asleep
•end/finish-----be over catch a cold-----have a cold come back—be back get up---be up •come/go/arrive/get/reach/move------be in/at
•join the army----be in the army/ be a soldier
•join the Party----be in the Party /be a Party member
•→My brother has been in the army for two years.
•→My brother has been a soldier for two years.
1. The manager left two hours ago.
The manager _____ ____ ____ for two hours.
分析：答案为has been away。

leave为非延续性动词，不能与for two hours这样的一段时间连用，而改成be away这样的延续性动词后，则可连用一段时间。

2. The film began five minutes ago.
The film has been _____ _____ five minutes.
分析：答案为on for。

has been提示时态是现在完成时态，“for+时间段”表示“持续（一段时间）”，常用在含有现在完成时态的句子里。

3. Mr Li joined the Party twenty years ago.
Mr Li _____ _____ _____ the Party for twenty years.
答案：has been in。

短暂动词join，意为“参加、加入（组织，政党）”，不能与延续时间状语连用，与延续性时间状语连用时，将join改成be in或be a member in…。

一时找不到相应的状态动词怎么办
如果一时找不到相应的动词或动词短语我们可用“It is ＋一段时间＋since从句（用一般过去时）”或“一段时间＋has passed＋since从句（用一般过去时）”这样的结构来表示，这样原来的终止性动词就可以保留下来。

如：It is four months since my elder sister went to Britain. （我姐姐去英国已有四个月了。

）More than three years has passed since Mary came to China. （玛丽来中国已有三年多了。

）
在上面两个句子中，我们既保留了终止性动词go与come,又表达出four months与more than three y ears这样的延续性时间状语的含义。

延续性动词与非延续性动词及其转换

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 : ⑴ for+一段时间 , 如 :for 2 years; ⑵ since 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. Y ou 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 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。
