现在完成时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have(has)表明事情发生于现在。
它和主语的人称、数要保持一致。
过去分词在句子中做谓语,说明句子的含义。
2.用法(1)动作发生在过去某个不确定的时间,但对现在有某种影响和结果。
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)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。
3.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。
时态现在完成时一.基本结构:助动词have/has+过去分词(done) 。
表示过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。
二.句型:否定句:主语+have/has+not+过去分词+其他.一般疑问句:Have/Has+主语+过去分词+其他.简略答语: Yes, 主语+ have/has.(肯定)No, 主语+ haven't/hasn't.(否定)三.用法1.“已完成”用法 :表示一个过去发生并结束的动作对现在造成的影响或结果。
这一类情况可以细致分为下述两种情况。
1)表示开始于过去的动作刚刚结束。
常和just,now,already,yet,not…yet等不确定的时间状语连用。
Li Ming has just turned off the light. 李明刚刚把灯关上。
(说明现在灯关上了)I've finished my homework now. 现在我已经做完作业了。
(说明可以交作业或做别的了)2)表示过去动作的结果,现在仍残留着。
一般不用时间状语。
I have lost my pen. 我把笔丢了。
(说明过去某时丢的,现在我还没找到这支笔)She has become a teacher. 她已经当了老师。
(说明她现在仍是老师)2.“未完成”用法。
表示动作或状态从过去某时开始,持续到现在的动作(用行为动词表示)或状态(be动词表示),常与for(+段时间)、since(+时间点或过去时的句子)连用。
①for+时段(for a long time,for a month)②since+过去一个时间点(译为:自从……以来,如since 1991 、since yesterday)③since+时段+ago (since 2 days ago)④since+从句(过去时)●⑤It is+时段+since+从句(过去时)⑥其它常见:today,this week(month),lately,recently,these days,in the past few days,during the last two weeks,,so far,up to now,till(until)now等。

现在完成时精讲和专练I.定义:表示过去发生或已经完成的动作对现在造成的影响或结果,也可以表示过去已经开始,一直延续到现在的动作或状态II.现在完成时的结构肯定句:have/has+ done (过去分词)否定句:主语+have/has+not+ done (过去分词)+其他.一般疑问句:Have/Has+主语+ done (过去分词)+其他.简略答语: Yes, 主语+ have/has.(肯定)No, 主语+ haven't/hasn't.(否定)注意:表示短暂时间动作的词,如:come,go,die,marry,buy等的完成时不能与for,since等表示一段时间的词连用。
用来持续的动作或状态或表过去重复的动作,如live,study,be,wait等,常和since(自从)或for(经历)引导的词语连用。
如:I have lived here for more than thirty years.我已在此住了30多年。
III.现在完成时的标志1.现在完成时的含义之一是过去完成的动作对现在仍有影响, 现在完成时通常和,ever, never, twice(once…), so far(到目前为止), since,for,in the past/last few years(在过去几年), already(肯定句), yet(否定,疑问句), just(刚刚), before(以前), recently (近来)等词连用说明:already与yet都有“已经”的意思,但already常用于肯定句,并用于句中。
yet 常用于否定句和疑问句,并用于句末。
例如:I have already finished my homework.I haven’t finished my homework yet. Have you finished your homework yet?They have left. (他们已经离开了,也就是说现在他们人不在这里)I have had my lunch. (我已经吃过午饭了,也就是说我现在不饿)I can’t find my watch now. I think I have already lost it.2.过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手。
(完整版)现在完成时讲解及练习题及答案时态讲解:现在完成时(1)构成:现在完成时由助动词have + 过去分词构成,助动词have 有⼈称和数的变化。
第三⼈称单数⽤has,其余⽤have.现在完成时的否定式直接在助动词后⾯加上not、疑问式是把助动词提到主语之前。
以study 为例,其否定式、疑问式和简单回答形式如下:(2)⽤法:1)现在完成时通常表⽰在说话之前已经完成的动作或存在的状态。
说话⼈强调的是该动作或状态对现在的结果或影响。
My daughter has just gone out. 我⼥⼉刚出去。
I’m sure we’ve met before. 我肯定我们以前见过⾯。
She has arrived. 她到了。
2)表⽰持续到现在的动作或状态,往往和包括现在在内的表⽰⼀段时间的状语连⽤,如recently, already, just, lately, for…, since…,yet等。
如:I haven’t heard from her these days. 这些⽇⼦我没有收到她的信。
We haven’t seen you recently. 最近我们没有见到你。
They have been away for two years. 他们离开已经两年了。
She has been with us since Monday.★注意:1)since和for的区别since后接时间点,如1993,last term, yesterday, the time I got therefor后接⼀段时间,表⽰“长达多久”,如ten years, a while, two days等。
Exercise: ⽤since和for填空1. Jim has been in Ireland ______ Monday.2. Jill has been in Ireland ______ three days.3. His aunt has lived in Australia ______15 days.4. Mary is in her office. She has been there ______ 7 o'clock.5. India has been an independent country ______1974.6. The bus is late. They've been waiting ______ 20 minutes.7. Nobody lives in those houses. They have been empty ______ many years.8. Mike has been ill ______a long time. He has been in hospital ______ October.2)表⽰短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等,在完成时当中不能和表⽰⼀段时间的状语连⽤,因为它们表⽰的动作不可能持续。
初中英语主要时态系列(六)——现在完成时讲解及练习1现在完成时的基本结构肯定句:主语+have/has+动词的过去分词+其他否定句:主语+have/has+not+动词的过去分词+其他一般疑问句:Have/Has+主语+动词的过去分词+其他特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词+其他)2现在完成时的用法1. 现在完成时用来表示过去已经完成的动作对现在造成影响或后果。
也就是说,动作或状态发生在过去但它的影响现在还存在,强调的是现在。
I have already posted the photo.我已经邮寄出了照片。
与此种用法连用的时间状语时一些模糊的过去时间状语,如already(肯定句句中), yet(否定句/疑问句句尾), just, before, recently,still, lately,never 等。
2. 现在完成时也可用来表示动作或状态发生在过去某一时刻,持续到现在并且有可能会继续持续下去。
He has lived here since 1978.自从1978年以来,他一直住在这儿。
(动作起始于1978年,一直住到现在,可能还要继续住下去。
)此种用法常与for(+时间段),since(+时间点或过去时的句子)连用。
谓语动词必须是延续性动词。
有些瞬间动词可变为延续动词:go out----be out finish----be over open----be open die----be dead buy---have fall ill---be ill come back----be back catch a cold----have a cold3现在完成时常见考法对于现在完成时的考查,多以单选、句型转换或词语运用的形式考查学生在具体语境中灵活运用时态的能力。
在考试中,会让大家判断是否该用现在完成时,或者是考查“瞬间动词”不能与表示一段时间的状语连用”这一知识点。
