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,

go,
arrive,
reach,
get
to,

一、延续性动词
延续性动词表示的动作不但可以延续，而且可以产生持久的影响。常见的这类动词有：be，have，keep，know，learn，lie，live，read，sing，sleep，stand，stay，wait，walk，watch等。延续性动词的用法很广，但常见于现在完成时中的句子中，且常与for，how，long，since等引导的表示一段时间的状语或状语从句连用。例如：
1．i
have
learned
more
than
1，000
chinese
words
since
i
came
to
china．
自从来到中国，我已经学会了l，000多个汉字。
2．we
have
lived
in
linqing
since
we
came
here．自从来到这儿，我们就一直住在临清。
3．i
have
kept
the
picture
for
about
three
years．这张画我保存了大约三年。
延续性动词又称持续性动词，它所表示的是一种持续的动作。
延续性动词可与表示一段时间的时间状语连用,而非延续性动词不行
举个例子：
(1)
how
long
have
you
had
it?
这辆车你买了多久了？
[说明]
在英语中，非延续性动词不能与表示一段时间的时间状语连用。所以我们不说“how
long
have
you
bought
it?”因为how
long
是“多久”的意思，而buy是非延续性动词，二者
不相配。常用的非延续性动词有：become,
begin,
buy,
borrow,
arrive,
come,
die,
fall,
finish,
get
to
know,
go,
join,
leave,
marry,
start,
stop等。为了表达这种意思，我们常用
相应的延续性动词
have,keep
或短语
“be+名词，形容词，位置副词，介词短语”
来代替非
延续动词。如：become---be,
begin---have/
be
on,
borrow---keep,
buy---have,
come---
be
here/there/in…,
die---be
dead,
finish---be
over,
join---be
in,
leave---be
away等。
例如：his
father
has
been
dead
for
one
year.(不能用die)
他父亲死了一年了。
my
brother
has
been
in
the
army
for
two
years.(不能用join)
我哥哥参军两年了。
i
have
kept
the
book
for
two
weeks.
(不能用borrow)
我借这本书两个星期了。
非延续性动词可用与现在完成时态,但由于动作是瞬时间完成的所以不能与for或since引出的时间状语连用.英语中常见的非延续性动词在完成时态中可改为相应的表示延续性的动词或短语,这时可与表示一段时间的的状语连用.
