何时用持续性动词

Question

如题所述

Answer 1

2）持续系动词
用来表示主语继续或保持一种状况或态度，主要有keep, rest, remain, stay, lie, stand, 例如：
He always kept silent at meeting. 他开会时总保持沉默。
This matter rests a mystery. 此事仍是一个谜。
-----------------
非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
（错）I have received his letter for a month.
（对）I haven't received his letter for almost a month.

延续动词与瞬间动词

1) 用于完成时的区别
延续动词表示经验、经历； 瞬间动词表示行为的结 果，不能与表示段的时间状语连用。
He has completed the work. 他已完成了那项工作。 (表结果)
I've known him since then. 我从那时起就认识他了。(表经历)
2) 用于till / until从句的差异
延续动词用于肯定句，表示"做……直到……" 瞬间动词用于否定句，表示"到……，才……"
He didn't come back until ten o'clock.
他到10 点才回来。
He slept until ten o'clock.
他一直睡到10点。

典型例题
1. You don't need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本题后句强调对现在的影响，我知道她的模样，你不用描述。再次，several times告知为反复发生的动作，因此用现在完成时。
2.---I'm sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的动作由过去开始，持续到现在，应用现在完成时。本回答被提问者采纳

Answer 2

浅谈终止性动词和延续性动词
延续性动词:
live,run,stay,clean,play,hold,watch,teach,read,study,teach,eat,drink,write,dance,
sing,smoke
瞬间性动词:
open,stop,like,love,die,win,close,shot,begin,start
enter,finish
1、终止性动词：表示不能延续的动作，即动作发生后立即结束。如：begin,arrive,borrow,buy,break,close,come,fall,dic,finish,go,leave,lend,mary,reach,receive,open,sell,start,stop等。
终止性动词的肯定式是不能持续的，所以不能和表示一段时间的状语连用，而终止性的否定式就可以和表一段时间的状语连用，因为否定本身就是可以延续的。
如：have
a
cold是持续性动词，表示“状态”，可与表延续性的时间状语连用，不定冠词不能省略。
i′ve
had
a
cold
since
my
arrival（到达
n.）.
i
didn′t
go
to
school
because
i
had
had
a
bad
cold
for
days.
catch
a
cold是短暂性动作，表“动态”：它不能和延续性时间状语连用，不定冠词“a”可有可无，catch可用take,get代替。
put
on
your
coat,or
you′ll
catch/take/get
a
cold.
take
care
not
to
get
cold.
但是，若cold前有形容词修饰时，则不定冠词不能省。
如：brown
has
taken
a
slight
cold.
注意下列句子：
i
have
caught
a
cold
for
over
a
week.(×)
i
have
had
a
cold
for
over
a
week.()
2、延续性动词：表示可以延续一段时间的动作或状态。如：be,drink,fly,eat,keep,lie,live,rain等。
延续性动词常不能和表示一个短暂具体的时间状语连用；这类动词如用于进行时态，则可以和表示一个短暂具体的时刻连用。
he
worked
at
eight
yesterday
afternoon.(×)
he
was
working
at
eight
yesterday
afternoon.()
3、代替终止性动词的方法

3、用be替代become
