现在完成时的用法总结
首先,现在完成时属于完成时这个范畴,它与过去完成时,将来完成时并列,它的结构组成为have/has+过去分词。
当我们说到各种完成时,大家都知道这个时态是强调动作“已完成”。
而现在完成时则是站在当下(即现在这一刻,这一秒)去判断一个动作,认为这个动作在当下(现在这一刻,这一秒)已经完成。
但是,请注意:即使一个动作的持续时间极短,那也是一个过程。
所以,当我们判断一个动作在当下这一刻已经完成时,我们已在潜意识中承认了这个动作是从过去开始发生的。
所以,当我们用到现在完成时的时候,我们其实已同时考虑到了过去和现在。
以上观点与现在完成时最常见的用法一密不可分,下面我们一起来看。
用法一:现在完成时用来描述与现在有联系,对现在有影响的已经完成的动作。
例如:Uncle Z is excited because he has just finished his 150,000-word essay.在这种用法中,常会出现关系从句来阐明动作之间的联系。
如上句,完成论文这个动作在说话时已经结束,但是完成论文带来的影响,即说话人的激动心情还在持续。
用法二:现在完成时用来描述已经完成的动作。
常用于用来描述最新的完成事件消息。
例如:Guess what? Uncle Z has just won the jackpot!这时,说话人使用现在完成时强调事件完成的时刻与说话的时刻很接近,这个消息是一个新闻。
用法三:现在完成时用来描述截至目前,已经重复完成过几次的动作。
例如:Uncle Z has thought about having a dog many times.在这种用法中,句中常常含有包含次数的部分,如xx times,或者如often, occasionally 这样的副词。
用法四:现在完成时用来描述从过去开始发生,并一直持续到现在的动作。
例如:Uncle Z and his best friend have known each other for 10 years.在这种用法中,常伴随出现表示一段时间的短语,如for 10 years, all day long 等等。

现在完成时的特殊用法
现在完成时的特殊用法1. 现在完成时的基本概念和用法现在完成时是英语中最常用的一种时态,它表示一个动作或状态一直持续到现在,并且还可能会继续下去。
在表达这种情况时,可以使用“have/has + 过去分词”的形式构成现在完成时。
例如: Ihave been studying English for 10 years (我已经学习英语十年了)。
现在完成时通常与表示时间段的状语连用,这样可以表达动作或状态发生的时间段以及其与现在的关系。
比如: I have beenworking here since 2010 (我从2010年开始在这里工作)。
2. 现在完成时的特殊用法一:强调结果现在完成时还有一个特殊的用法,就是强调一个动作产生的结果。
这时候,我们通常使用“have/has + 过去分词”+ 名词/形容词/副词等形式来表达。
例如:I have finished my homework (我已经完成了作业)。
这种用法通常与表示时间段的状语连用,以强调结果产生的时间段。
例如:She has been working hard, and her English has greatly improved (她一直在努力工作,英语水平已经有了很大的提高)。
3. 现在完成时的特殊用法二:经验现在完成时还有一个特殊的用法,就是表达一个人的经验。
这时候,我们通常使用“have/has + 过去分词”+ ever/never等形式来表达。
例如:We have never been to Paris (我们从未去过巴黎)。
这种用法通常表达对某个事情的经验或者对某种状态的感受。
例如:I have never felt so alive (我从未感觉如此活着)。
4. 现在完成时的特殊用法三:动作的反复或延续状态现在完成时还有一个特殊的用法,就是表示一个动作的反复或一个状态的延续。
这时候,我们通常使用“have/has + been + 过去分词”的形式来表达。
初三英语专项辅导五——现在完成时(二)
初二英语现在完成时(二)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,进一步学习现在完成时。
一、*“终止”、“延续”要转换英语中的动词从词义上可以分为延续性和非延续性两种,在现在完成时态中一定要注意动词这一特性,应将这类非延续性动词转换为延续性动词。
如:“The cat play”has been on for half an hour.《猫》已经开演半个小时了。
How long have you had this dictionary?这本字典你买了多久了?初中阶段常见的有:come-be, go out -be out, leave-be away (from), begin-be on, buy-have, borrow-keep , join-be a member / 介词短语, die-be dead, become-be, open(v.)-be open(adj.) 等。
二、* 时间“点”、“段”须分清过去开始的动作可以延续到某一点结束,也可能继续延续,这时就要根据时间“点”、“段”选择相应的介词for或since。
如:He has been away for two years.他已走了两年。
(for+时间段)He has been an English teacher since 1992.自从1992年以来他一直当英语教师。
(since+过去某一时刻)三、简单过去时和现在完成时在一定程度上有共同之处,当然事实上两者之间有本质区别。
当需要指明过去一个特定的时刻发生的事情时,需要使用简单过去式。
He finished three days ago.他三天前做完了工作。
They finished a long time ago.他们老早就完成工作了。
四、当没有特定指明的时间,现在完成时和一般过去时都可以使用。
I have already finished.我早就完工了。

3.表示一直持续到现在的状态 The meeting has lasted five days. 4.在时间状语从句,条件状语从句或让步状语从句中表达将来某时已 经完成的动作 When you have learned English, you will find it a bridge to so much knowledge. We’ll start at six if it has stopped raining by then. ※这里的现在完成时强调从句动作在主句动作之前完成, 如果两个 动作同时或几乎同时发生, 则不必用完成时 .试比较: I’ll let you know as soon as I hear from her. She will call you when she gets home. 5.特殊句型: It’s the first time that… have/has done…. It has been/is + 时间段 +since …. This is the best film that I have ever seen. 6.短暂性动词的完成时不与时间段连用, 如需连用可转化成相应的
