英语现在完成时解释

英语现在完成时解释

英语现在完成时解释全文共四篇示例,供读者参考第一篇示例:英语现在完成时是英语语法中的一个时态,用来表达过去发生的动作或事情对现在造成的影响或结果。

在英语中,现在完成时使用have/has + 过去分词的形式来构成,用来描述从过去某一时刻一直延续到现在的动作或事件。

现在完成时通常用来表达以下几种情况:1. 表示已经完成的动作或经历:例如:I have finished my homework.(我已经完成了我的作业。

)这个句子表示我已经完成了我的作业,目前作业已经做完了。

2. 表示曾经做过的事情对现在的影响:例如:I have lived in Beijing for five years.(我在北京住了五年。

)这个句子表示我在过去的五年里一直住在北京,现在可能依然住在北京。

3. 表示从过去某一时刻一直延续到现在的动作或事件:例如:She has worked at this company since 2010.(她从2010年开始就在这家公司工作。

)这个句子表示她从2010年开始一直在这家公司工作,目前仍在这家公司工作。

需要注意的是,现在完成时常常与表示一段时间的状语连用,如for,since等,用来表明动作或事件发生的时间跨度。

现在完成时通常不能与一些表示具体时间的状语连用,如yesterday,last week等。

如果要表达具体时间的动作或事件,应该使用一般过去时。

现在完成时在英语语法中扮演着重要的角色,帮助我们表达过去与现在的关系,强调过去的经历对现在的影响。

通过掌握现在完成时的用法和结构,我们可以更准确地描述和理解英语中的动作或事件。

第二篇示例:英语现在完成时是英语语法中的一个时态,表示过去发生的动作或情况对现在产生的影响或结果。

它通常由have/has + 过去分词构成。

例如:"I have visited Paris."(我去过巴黎)。

英语现在完成时与一般过去时的区别在于,一般过去时强调过去某个具体的时间点或时间段内发生的动作或事件,而现在完成时则强调过去发生的动作或事件对现在的影响或结果。

现在完成时的四种用法

现在完成时的四种用法

现在完成时的四种用法现在完成时是英语中一个很重要的时态,也是很容易弄错的一个时态。

归纳起来,现在完成时共有四种主要用法,现分别解说如下:一、现在完成时表示影响该用法的现在完成时表示一个过去发生的动作在过去已经完成,并且这个过去发生并完成的动作对现在有影响或结果,同时说话者强调的或感兴趣的就是这个影响或结果,如汉语说“他已离开这个城市了”,其中的“离开”肯定发生了,它对现在的影响或结果就是“他现在已不在这个城市了”;又如汉语说“有人把窗户打破了”,显然“打破窗户”这一动作发生在过去,并且在过去已经完成了,但说话人强调的重点是打破窗户对现在的影响——窗户现在仍是破的。

如:He has left the city. 他已离开这个城市。

​(结果:他不在这个城市。

​)Someone has broken the window. 有人把窗户打破了。

​(结果:窗户仍破着。

​)I have lost my pen. 我把钢笔丢了。

​(结果:我现在无钢笔用。

​)He has finished his work. 他把工作做完了。

(结果:他现在可以做其他的事了。

)二、现在完成时表示持续该用法的现在完成时表示一个过去发生的动作或开始的状语在过去并未完成或结束,而是一直持续到现在,并且有可能继续下去​(也可能到此结束​),如汉语说“他在我们学校教书已有​30年了”,显然“他在我们学校教书”是从​30年前开始,并且一直教到现在,已经持续了​30年;又如汉语说“自上个星期以来他一直很忙”,显然“忙”是从上个星期开始的,并且这一“忙”就一直忙到现在。

如:He has taught in our school for 30 years. 他在我们学校教书已有​30年了。

He has been busy since last week. 自上个星期以来他一直很忙。

完成时篇(一)——现在完成时[提问] 请问在句子“Working in London has been the best decision I have made so far. (Experiencing English Integrated Book1 Page71)”中,为什么时间状语是完成时的情况下,主句仍然可以使用现在完成时呢?答:完成时态通常表示已完成或已经开始从事的动作,它可以分为现在完成时、过去完成时、将来完成时以及完成进行时。

根据定义我们可以了解到,除了表示到现在为止动作已经完成或已经开始以外,还有多种情况可以用现在完成时来表达。

一、动作从过去某个时间开始发生,延续到现在,并且说话前已经完成。

例如:The mission has been carried out well.任务已经很好地完成了。

Those girls have eaten two big cakes.女孩们已经吃了两个蛋糕了。

二、某个动作或状态发生在过去,持续并影响现在,有可能会继续保持下去。

例如:My brother has been abroad for several years.我哥哥已经出国好几年了。

It has rained all morning.雨下了一个早晨。

Up to now, parents have accepted the pop music youths prefer to.现在,家长们已经接受了年轻人喜欢的流行音乐。

I have known him since the summer in 2001.自2001年的那个夏天,我就认识他了。

三、动作发生在现在之前的某个时间,可能是多次动作的集合,也表示习惯性的动作或状态。

例如:Xiao Qin has come over here three times in the daytime.白天小覃已经来过三次了。

Which countries have you traveled recently?最近你都去过那些国家?How many papers have you read today? 你今天看了几篇论文?四、动作过去曾发生过一次或多次,也可能是一种经历。

常与for (+时间段),since(+时间点)连用.Mary has been ill for three days.Mary has been ill since three days ago.注意:1.现在完成时不能单独与准确时间连用,(如表示过去的时间状语)如yesterday(morning、afternoon),last(morning、afternoon)等,除非与for, since连用.2.现在完成时往往同表示不确定的过去时间状语连用,如already(肯定), yet(否定,疑问), just, before, recently, still, latel y等:He has already obtained a scholarship.I haven't seen much of him recently (lately).We have seen that film before.Have they found the missing child yet ?3. 现在完成时常常与表示频度的时间状语连用,如ever, never, twice, several times等:Have you ever been to BeijingI have never heard Bunny say anything against her.I have used this pen only three times.
