一般过去时态和现在完成时态的区别练习

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

night/week/month/year…,…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“have/has+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 first/second...time that...。”或在“it/this/that 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 cl ose →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)

have/has 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。

现在完成时讲解与练习 1.构成现在完成时是由助动词 have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和 主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。 2.用法 (1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如: -Have you had lunch yet -Yes,I have. I've just had it.你(已经)吃午饭了吗我刚刚吃过。(现 在我不饿了) (2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等 表示一段时间的状语。\ 如:He has taught here since 1981他自1981年就在这儿教书。(可能还要继续教) I have't seen her for four years. 我有四年没见到她了。 3.结构 1).陈述句结构:主语+have( has)(not)+过去分词+其它。have not=h aven’t has not=hasn’t. 2).一般疑问句结构:Have( Has )+主语+过去分词+其它 3).特殊疑问句:特殊疑问词+have(has) +主语+ 过去分词+其它 eg. He has already finished his homework. He hasn’t finished his homework yet. Has he finished his homework yet --Yes, he has./ No, he hasn’t./ No, not yet. (3)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有twice, ever, never, three times等时间状语。如: I have been to Beijing twice.我去过北京二次。 4.现在完成时的时间状语 (1)现在完成时属于现在时范围,故不能和过去的时间状语连用。如:yesterday,last Sunday,in1990,three years ago等。但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用。 a. 用副词already和yet。already一般用于肯定句中,yet一般用于否定句和疑问句中。如:We have already finished our homework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。 b.用ever 和never。多用于否定或疑问句中,表示“曾经”或“从未“等。如 -Have you ever been to the Great Wall你曾经去过长城吗 -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语,如just, before, up to now, the past few years等。例如: I have seen her before, but I can not remember where.我以前见过她,但记不起在哪里见过。 He has been there three times the last few years.近几年他去过那里三次了。 d.用包括“现在”在内的时间状语,如:now, today, this morning (month ,year, term)等。例如 -Have you met him today-No,I haven't.今天你见过他吗我没有。 How many times have you been there this year 今年你去过那里多少次 (2)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 begin(start)→be on die →be dead come back→be back leave →be away fall ill(sick,asleep)→be ill(sick,asleep) get up→be up go out → be out finish →be over put on →wear 或be on open →be open join →be in或 be a member of… close →be closed go to school→be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study→study come to work →work等 如:He has been a soldier for three years.他参军三年了。

现在完成时态讲解

语法探知:现在完成时态 一、掌握结构:助动词have/has + 动词的过去分词 二、掌握用法: 1.表示过去发生的某一动作对现在造成的影响或结果,常与一些时间状语,如:already, yet, ever, never, just, before, once, twice (次数)等连用,也可以和包括现在在内的时间状语,如these days, today, recently, this year, so far(=by now)等连用. e.g. I have already posted the letter. (信已经不在我这儿了) 2.表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段,since+时间点/从句, in(during) the last(past) ten years等,谓语只可用延续性动词。 我们知道英语动词根据词义可分为两种,一种是延续性的,一种是终止性的,终止性动词(也可称为非延续性动词,瞬间动词,或短暂性动词),如begin, start, die, buy, leave, come等,表示动作在一瞬间之内就能完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+段时间,since+点时间/从句连用,也不能用在how long引导的特殊疑问句中。(但在否定句中短暂性动词可以与for和since短语连用。) 如:They’ve left London for five days. (×) They’ve been away from London for five days. (√) 三、掌握短暂性动词如何转换成延续性动词 常见短暂性动词与延续性动词的对应关系如下: come/go/arrive/get/reach/move—be in/at open—be open die—be dead close—be closed become—be borrow—keep begin/start—be on put on—wear leave—-be away (from) buy—have fall asleep(ill)—be asleep(ill) end/finish—-be over catch a cold—have a cold join the army—be in the army/ be a soldier join the Party—be in the Party/ be a Party member get to do —do (get to know—know) get married —be married get up —be up begin to do —do (begin to study—study)
