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 5
o'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。
leave --- be
away, borrow --- keep, buy --- have,

2. He joined the Party 2 years ago.
-----He __________________the Party for 2
years.
3. I bought the book 5 days ago.

现在完成时(一
现在完成时是初三教材中的一个重点语法项目,下面我们就来学习它的构成。
现在完成时的基本句式是 “have (has +过去分词 ” 。如:
① I
have seen that film.我已经看过那部影片了。
② We have just
finished our homework.我们刚刚做完家庭作业。
③ She has
gone home.她回家去了。
1.
注意:1该句式中的 have 或 has 是助动词, has 用于第三人称单数,其它人
称一律
用 have 。 2该句式中 have (has 和过去分词之间可用 just 插入。
3 把该句式译成汉
语时,往往用 “ 已经 ” 、 “ 刚刚 ” 、 “ 过 ” 或 “ 了
” 等。
2.现在完成时的一般疑问句式是把助动词 have 或 has 提到主语之前。如:④
Have you read this story book yet?你读过这本故事书吗?
⑤ Has he eaten that apple yet?他吃那个苹果了吗?
注意:1现在完成时的一般疑问句往往在句末加 yet 。 2把现在完成时的一般
疑
问句译成汉语时,往往译成 “…… 过吗? ” 、 “ 还有 …… 吗? ” 等。
3其肯定回 答
用:Y es , . . . have (has .否定回答用:No , .
. . haven't (hasn't .有时用: No , not yet.或 No ,
never .
3.现在完成时的否定句式是 “have (has +过去分词 ”
。如:
⑥ We haven't studied Unit 2yet.我们还没学习第二单元。
⑦ The train hasn't stopped yet.火车还没有停下来。
注意:1现在完成时的否定句句末往往加 yet 。 2否定句常译为 “ 还没有 ……”
等。
现在完成时(二
现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果。如:
Have you
read that story?你读过那个故事吗?(“ 读 ” 这一动作发生在过去,对
现在造
成的影响是:是否知道故事的内容
I have bought two
apples.我买了两个苹果。 (“ 买 ” 这一动作发生在过去,对现
在造成的结果是:拥有两个苹果
在学习这一概念的同时,还应注意常与现在完成时连用的几个副词:already , just ,
yet , ever , never 等。 already , just 多用于肯定句中,
yet , ever , never 多用于疑问句和
否定句中。如:
I have
already finished my homework.我已经做完家庭作业了。
He
has just had his meal.他刚吃过饭。
Have you ever
sung this English song?你曾唱过这首英文歌吗?
They
haven't started yet.他们还没有动身。
W e have never
heard of it.我们从来没有听说过这件事。
现在完成时(三
1.现在完成时态既涉及过去,又联系现在,它可表示动作或状态过去已经开始
一
直延续到现在,和由 for 或 since 引导的时间状语连用。例如:
W e
have lived here for five years.我们在这里住了五年了。
I
have known him since he was a
boy.我从他还是个孩子的时候就认识他了。
注
意:现在完成时与一般过去时的区别:现在完成时强调过去发生的事对现在
造成的影
响;一般过去时指过去发生的事实。请看下面对话中一般过去时和现
在完成时的不
同。
A :Have you seen the film? B :Y
es , I have.
A :When did you see it? B :I saw
it a year ago.
2.延续性动词与非延续性动词在现在完成时中的使用。
(1 延续性动词:be , have , know , live ,
work , study , learn , teach , speak , talk ,
draw , wait , wear , walk , sleep
等,这些动词可以和表示一段时间的状 语连用。例
如:Uncle Wang has worked
in this factory for ten years.王伯伯在
这家工厂工作十年了。
(2 非延续性动词:come , go , arrive , reach , see ,
hear , close , leave , begin , start ,
lose ,
buy , fall , join , die 等,这些动词可用于完成时态,说明某个动
作的结果还存在,
但不能和表示一段时间的状语连用。例如:
【正】 The play
has begun.戏开演了。 (戏正在演着
【误】 The play has begun
for half an hour.戏开演半小时了。
3.非延续性动词表示状态有三种方法:
(1用相应的延续性动词来替换非延续性动词。句中的谓语动词一般用现在完
成时,
时间状语为 “for +时间段 ” 或 “since +时间点 (过去某一时刻或非延续性
动词
的一般过去时从句 ” 或用在 how long的问句中。例如:
They
have been here for five years. 他们来这里已经五年了。 (这里
come 这一非
延续性动词改成了 be 。
常见的非延续性动词与延续性动词转换如下:come→be , come to→be in at
, go
out→be out , leave→be away , begin
start→be on , buy→have , borrow→keep ,
join→be
a member of be a. . . member , die→be dead, put
on→wear , catch a cold→
have a cold, get to
know→know , become a teacher→be a teacher, fall
asleep→be asleep,
go to sleep→sleep 等。
(2用
“ 非延续性动词的一般过去时+一段时间+ago” 这一句型(即用一般过 去
时
。例如:They came here five years ago.他们是五年前来这里的。
(3用 “It is(has been+时间段+since
从句(从句的谓语动词用非延续性动 词的过
去式 ” 这一句型。例如:
It is
five years since they came here.自从他们来到这里已经有五年了。
