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

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,yes
terday,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

几点注意事项

精品文档
(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。
