二,
Since

for
区别

Since +
时间点,具体时间






I have been in Beijing since 2010.

、以来,从、


、以后”

用来说明动作起始时间


2

For +
时间段,用来说明动作延续时间长度,因此句中的谓语动词,也应该是延续
性动词。


I have been in Beijing for one year


We have learnt English for about three years.


I have
been
here for 3 days. (

)


I have
arrived
here for 3 days.
(误)










终止




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。



open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy
等。














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



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





















at eight
表示
点时间


前后显然矛盾。
如果用延续性动词性动词来表
示一瞬间的动作,可借助
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.(

)
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.
















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.






























































语用

(
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.


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
