一般过去时态和现在完成时态的区别练习题
1)一般过去时态表示过去某
时发生的动作或单纯叙述过去的
事情,强调动作;现在完成时态中动作为过去发生的,强调过
去
的事情对现在的影响,强调的是影响。 如:I saw this film
yesterday.
(强调看的动作发生过了)
I have already seen this
film.(强调对现在的影响,电影
的内容已经知了) I haven’t finished
my work yet. (强调
对现在的影响,还有工作要做,不能去玩) When did
you finish
your homework?
(询问过去的动作所发生的时间,与现在无关)
2)一般过去时态表示动作在过去已经停止;现在完成
时态表
示过去开始的动作一直延续到现在。
如:Ann visited her
uncle last weekend.(visit这个动作
在过去已经停止) They
have lived here since 1983.
(live here
这个动作从1983年开始,一直延续到现在)
3)一般过去时态常用非延续性动词,如borrow, buy, come, go,
leave, start, die, finish, become等。现在完成时态可表
示持续到现在的动作或状态,与时间段连用时动词一般是延续
性的,如keep, have,
live, teach, learn, work, study, know,
be等。
如:He joined the League three years ago
.(join
是短暂动词)
.
.
He has
been in the League for three years.(be
in表状
态,在团内的状态可延续) He has been a League member
for
three years. (是团员的状态可延续)
4)一般过去时态常与具体的
时间状语连用,而现在完成时态
通常与模糊的时间状语连用,或无时间状语。
一般过去时态的时间状语:yesterday, last
nightweekmonthyear…,…ago, in1980, just
now等,皆
为具体的时间状语.
现在完成时态的时间状语:for+时间段,
since+过去的时间点
一般过去时态的句子, so far, , up to now, in
the
past ....years, 等,皆为不确定的时间状语。 如:Tim wrote
a letter to his brother last night.
(last
night 为具体的过去时间状语,所以用一般过去时态)
I’ve learned
English for three years .
(for three
years为时间状语,是个时间段,时间跨度大,
不具体)
学以致用
1.——When _____ you _____ to learn to skate?
----Five years ago.
.
.
A.
do; start B. will; start现在完成时态 详细讲解及
其练习
一、现在完成时由“havehas+过去分词”构成,主要有两个
含义:
①表示过去发生的动作对现在造成的影响和结果,常用的
时间状语有many
times,just,yet,ever,never,just,
already,so far,
by now等。
I have already watched the TV play.
我已经看过这部电视
剧了。(现在我对它不感兴趣了)
——Have you found
your lost pen yet?
——No, I haven’t found it
yet.(我很着急)
②表示动作或者状态在过去已经开始,持续到现在,也许
还将持续下去。用于延续性动词,常常与so
far、for或者since
短语连用。since + 时间点 从句,for +
时间段,如for two
months等。
二 、现在完成时态和一般过去时态的区别
1)现在完成时和一般过去时都能表示过去发生过的动作,但
现在完成时表示过去动作对现在的
影响,并且表示这一动作已
完成或还可能继续下去;
.
.
2)而一般过去时与现在的情况没有联系,仅表示过去的动作,
且这一动作到说话时已终止。因此现在
完成时不能与表示明确
的过去时间如:in1949,yesterday,last week等的状
语连用,
并且用when或where对这些时间和地点状语提问时,一般只
用一般过去时。
三、在“it is firstsecond...time
that...。”或在
“itthisthat is the
+最高级+名词+that...。”结构中,
that从句中的动词常用现在完成时;在“it +
be ...+since
从句”这一结构中,be可用一般现在时或现在完成时,since
从句一般用过去时。
现在完成时可以和带有 since 或 for
等表示“一段时间”
的状语连用,表示动作或状态从某一时刻开始,一直持续到现
在。如:
I haven't seen him for two years.
但是,像
come, arrive, buy 等终止性动词不能与表示“一
段时间”的状语连用。要用,必须
改为“be(在)”等延续性
动词来表述。
现归纳总结一下由非延续性动词到延续性动词的转换:
arrive→be here
.
.
die →be dead
begin(start)→be on come
back→be back fall
ill(sick,asleep)→be ill(sick,asleep) leave
→be
away get up→be up finish →be over
open
→be open close →be closed borrow
→keep 或 be
on →be in 或 be a member of… go to
school→be a
student buy →have catch(a
cold)→ have(a
cold) begin to study→study
get to know
→know come to work→work 等
如:He has been a soldier for three
years.他参军三年了。
His father has been dead for two
years.他父亲去世二年
了。
The film has been on for
ten minutes.电影已开始十分
钟了。
We have studied
English for three years. 我们(开始)
学英语已三年了。
几点注意事项
(1)have been(to)与 have gone(
to)的区别:have been(to)
表示“去过某地(现在已经回来了)”,可用于
各人称;have
gone(to)表示“去某地了(说话时某人不在当地)”,常用于
.
.
第三人称,前者可与 once , never, several
times 等连
用,后者则不能。
He has been to
Beijing.他去过北京(已经回来了)
He has gone to Beijing .
他去北京了。 (还没有回来)
havehas been in 待在某地
如:They
have been in Beijing.他们呆在北京。
(2)终止性动词现在完成时的否定式
,已变成一种可以延续
的状态,因此可以和表示一段时间的状语连 用。 如:
I
haven't left here since 1997.自从 1997
年以来,我一
直没有离开过这儿。
