如今完成时【1 】一.如今完成时组成组成:如今完成时由助动词have + 曩昔分词组成,助动词have 有人称和数的变更.第三人称单数用has,其余用have.如今完成时的否认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,其否认式.疑问式和简略答复情势如下:1.如今完成时平日暗示在措辞之前已经完成的动作或消失的状况.措辞人强调的是该动作或状况对如今的成果或影响.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.暗示中断到如今的动作或状况,往往和包含如今在内的暗示一段时光的状语连用,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. 比来我们没有见到你.They have been away for two years. 他们分开已经两年了.She has been with us since Monday.①for+时段②since+曩昔一个时光点(译为:自从……以来)③since+时段+ago④since+从句(曩昔时)⑤It is+时段+since+从句(曩昔时)Mary has been ill for three days.I have lived here since 1998.留意:since和for的差别since后接时光点,如1993,last term, yesterday, the time I got therefor后接一段时光,暗示“长达多久”,如ten years, a while, two days等.3.暗示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等,在完成时当中不克不及和暗示一段时光的状语连用,因为它们暗示的动作不成能中断.是以,不克不及说:He has come here for 2 weeks. ×The old man has died for 4 months. ×They have left only for 5 minutes. ×4.has gone (to),has been (to), has been (in) 的差别Have/Has gone(to) :去了(如今不在措辞现场,可能在路上和已经到)Where is your father?He has gone to Shanghai.Have/Has been (to) :去过(已不在去过的地方)My father has been to Shanghai.Have/has been in:呆了多久(还在所呆的地方)My father has been in Shanghai for two months. /since two months ago.5.如今完成时不克不及和暗示曩昔的时光状语连用,如yesterday, last year, in 1976, two days ago, just now, when I came in,但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用.不克不及与when连用.如今完成时往往同暗示不肯定的曩昔时光状语连用例如:She has already come. 她已经来了.I haven’t read it yet. 我还没读过这个.I have met him before. 我从前曾见过他.Ma Hong has always been a good student. 马红一向是个勤学生.I have often seen him in the street. 我经常在街上看见他.They have never been to Yan’an. 他们从未去过延安.I haven't seen him lately. 我比来没看到他.三.如今完成时的标记1.如今完成时的寄义之一是曩昔完成的动尴尬刁难如今仍有影响,用以下四大标记词可以表达这种寄义:* 以already, just和yet为标记He has already got her help.他已得到她的帮忙.He has just seen the film.他方才看过这场片子.He hasn't come back yet.他还没有回来.* 以ever和never为标记This is the best film I have ever seen.这是我曾看过的最好的一部片子.He has never been to Beijing.他从没有到过北京.* 以动作产生的次数为标记He says he has been to the USA three times. 他说他已经去过美国三次了.* 以so far(到今朝为止)为标+beforeHe has got to Beijing so far.到今朝为止他已到了北京.She has passed the exam so far.到今朝为止她已经经由过程了测验.2.曩昔已经开端的动作一向延续到如今, 甚至有可能中断延续下去,我们可以从动作“延续”的特征和“时光”点段的区分入手,进一步进修如今完成时.①for+时段②since+曩昔一个时光点(曩昔从句)为标记四. 刹时动词buy, die, join, come,go ,leave, join ……不克不及直接与for since 连用.要转变动词buy----have borrow -----keepcome/arrive/reach/get to-----be ingo out----be out leave ----be awaybegin-----be on finish----be overopen----be open close -----be closeddie----be dead1.have代替buyMy brother has had(不克不及用has bought) this bike for almost four years.2.用keep或have代替borrowI have kept(不克不及用have borrowed) the book for quite a few days.3.用be替代becomeHow long has your sister been a teacher?4.用have a cold代替catch a coldTom has had a cold since the day before yesterday.5.用wear代替put on6.用“be+形容词”代终止性动词be+married代marry be+ill代fall (get) illbe+dead代die be+asleep代fall (get) asleepbe+awake代wake/wake up be+gone代lose,die,sell,leavebe+open代open be closed代close/shutbe+missing(gone,lost)代lose7.用“be+副词”代终止性动词be+on代startbegin“be+up”代get up“be+back(to)”代return to, come back to, go back to“be here (there)”代come(arrive, reach, get) here或go (arrive, reach, get) there8.用“be+介词短语”代终止性动词1.“be in/at +地点”代替go to /come to2.用be in the army 代替join the army3.“be in/at +地点”代替move to经常应用刹时动词变延续性动词表:1. have arrived at/in sw. got to/reached sw. come/gone/moved to sw.→have been in sw./at…响应的介词2. have come/gone back/returned → have been back3. have come/gone out →have been out4. have become → have been5. have closed / opened→ have been close/open6. have got up → have been up;7. have died → have been dead;8. have left sw. → have been away fro m sw.9. have fallen asleep/got to sleep → have been asleep;10. have finished/ended/completed → have been over;11. have married → have been married;12. have started/begun to do sth. → have done sth. ;13. have begun → have been on14. have borrowed/bought →have kept/had15. have lost → haven’t had16. have put on →have worn17. have caught /get a cold → have had a cold;18. have got to know → have known19. have/has gone to → have been in20. have joined/have taken part in the league/the Par ty/the army→have been a member of/ have been in/have been the Party’s member/the league member/the soldier…。

现在完成时讲解

现在完成时讲解

现在完成时讲解如何使用现在完成时同学们我们已经研究了现在进行时、一般现在时、一般过去时、一般将来时这4种时态的用法,但这4种时态还不能满足我们表达的需要。

比如:表示“某人过去曾经做过某事”或者“某人做某事多久”,以上五种时态就派不上用场了。

这时,我们可以用一种新的时态——现在完成时表示。

一、现在完成时的构成(一)肯定式主语+助动词have/has+过去分词+其它说明:这里的have/has是助动词,没有什么具体意义。

当主语是第三人称单数时助动词用has,其余人称一律用have。

has,have的缩略式分别为's或've。

规则动词过去分词的构成与过去式的构成方式一样,不规则动词可参看不规则动词表。

实例:1)I've just copied all the new words.我刚抄写了所有的生词。

(表示不要再抄了)2)She has lost her XXX.她丧失了她的书。

(透露表现到目前为止还没有找到)(如果用过去时:XXX .则强调书是过去丢的这一动作,而不知现在有没有找到)3)We've just cleaned the classroom.我们刚好打扫了教室。

(表明现在教室是干净的)(二)否定式主语+助动词have/has+not+曩昔分词+别的申明:目前完成时组成否认句时,只需在助动词have/has背面加not就行。

have not,has not的缩略式分别为haven't,hasn't。

另外,一定句中有some,already时,改成否按时要分别改成any,yet。

实例:1)I XXX.我还没有完成我的功课。

2)XXX.她没有坐火车旅行过。

3)We have XXX foreigner.我们历来没有和外国人说过话。

注:有时not可以用never代替,表示“从来没有”的意思。

又如:4)I have never seen him before.以前我从来没有见过他。

2. 表示从过去某一时间点开始到现在一直持续的动作:
①She has worked at this company since 2010.(她从2010年起在这家公司工作。

)这里表示过去从2010年开始工作,到现在一直在这家公司工作。

3. 表示过去已经发生但时间未具体提及的动作:
①Have you ever been to Paris?(你去过巴黎吗?)这里表示过去是否有去过巴黎,但并未提及具体时间。

需要注意的是,现在完成时强调的是过去的动作与现在的关系,因此常用于包含现在的句子中。

同时,现在完成时通常与表示一段时间的时间状语连用,如for、since等,以强调动作的持续性或延续性。

另外,现在完成时不能与明确的过去时间状语连用,如yesterday、last week等,因为这些表示过去具体时间点的状语与现在完成时的
概念不符。

在这种情况下,应使用过去时态表示过去发生的动作。

总结
I lived in Wuwei ten years ago. I have lived in Wuwei for ten years. I have lived in Wuwei since ten years ago.
I studied English ten years ago. I have studied English for ten years I have studied English since ten years ago.
Tips:buy 这个动作 从“开始发生”到 “结束/终止”, 几
乎同时或在极短的时间里(如‘几秒钟/几分钟内’)就完 成了“开始—结束”的过程,这样的动词我们叫做短暂性 动词。 所以, “我买了这块手表5年了”,在汉语中说的 通,但英语中就必须用相应的延续性动词来替换。
