2013-03-24 15:52阅读：
短暂性动词也称做终止性动词、非延续性动词或瞬间动词，表示动作不能延续，只是一瞬间就 结束的动作．
常见的短暂性动词有： come,
go, arrive, reach, see, hear,
close, open, leave, begin,
start, lose, buy, fall, join,
die, become, borrow, get up
等．
用法：
１、它们可以用于完成时态，说明某个动作的结 果还存在．
e.g. He has come back. The
film has begun
2、这类动词不能和表示一段时间的状语连 用，但在否定句中，非延续性动词也可以
用表示一段时间的状语来修饰．
e.g. I haven’t heard from
Uncle Wang for a long
time. We haven’t seen him
since 1992. She hasn’t left
home all her life.
3、还可改用一般过去时来表达．
e.g. He came back a week
ago.
4、也可用“It is
＋一段时间＋since…”句型
来表达．
e.g. It is a week
since he came back. 非延续性动词可以转换成延续性动词，主要 有以下几种：
①、用相应的延续性动词；
buy ---have, borrow ---keep, put
on ---wear, catch/get a cold
---have a cold, come/go/become
--- be.
②、转换成 be＋名词;
join the Party ------ be a
Party member, join the army
------ be a soldier, go
to school ------ be a
student.
③、转换成 be + 介词短语
: go to
school ------ be in school,
join the army ------ be
in the army. ④、转换成 be +
adj./adv. : die ------ be
dead, begin/start ------ be on,
close ------ be closed, fall
asleep ------ be asleep.

短暂性动词， 短暂性动词，延续性动词和现在完成时
短暂性动词是指动作一旦发生就立即结束。它不能和一段时间连用。这类动 词有：go, come, arrive, leave,
begin, start, join, marry
等；短暂性动词的肯定式 不能与表示一段时间的
for
或 since 或
how long
等状语连用。例如： His father got ill. I
have received his letter.
但是，不可以说：His father got ill
for a week. I have
received his letter for three
days. 在否定句中，短暂性动词可以和表示一段时间的状语连用。例如： We haven’t heard from
Jane for a long time. I
suppose something must have
happened to her. 延续性动词是指动作发生后还可以延续一段时间或者相当长的一段时间。 如：live, work, study, learn,
sleep 等，延续性动词可以和表示一段的时间状语连
用。 值得注意的是，表示一段时间的状语除了“for+一段时间”外，还有 since+n./
从句（时间点） ，since+时间段+ago，疑问词 how
long，in the past+时间段， all
these+时间段，from…to（时间点）以及
till/until+n./句子等等。例如：
How long
_______ your brother
joined
