初中英语现在完成时详解
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…。

九年级英语语法知识—现在完成时全国通用知识精讲
九年级英语语法知识—现在完成时全国通用【本讲主要内容】语法知识——现在完成时【知识总结归纳】一. 现在完成时的时间状语现在完成时的时间状语(包括副词、短语、从句等)主要有三种类型,分别用于不同意义的句子之中。
1. 表达“现在刚刚完成”的动作:副词:just, already, yet, recently(lately, etc)短语:so far, these +(最近)一段时间,etc2. 表达某种经历或经验副词:ever, never, once, twice, before, etc常用句:How many times…?3. 表达“过去继续到现在的动作或状态”,常与for和since连用,如:for two weeks, for a long timesince + 过去时间点/ n. / 一段时间+ ago / 一般过去时的从句在以上的时间状语中需要认真区别的就是“since + 一段时间+ ago”这个结构,它与“一段时间+ ago”含义不同,前者为时间段,后者为时间点。
二. 一般过去时与现在完成时的比较1. 在表达“过去的经历、经验”的概念时,如果时间不确定,用现在完成时,如果时间确定,则用一般过去时。
eg.I’ve met him before.I met him two days ago.2. 在when或what time引导的特殊疑问句中,不能用现在完成时。
eg.When have you visited New York?When did you visit New York?3. 过去发生的连串动作,如用and, but, or, so等对等连词连接,要用一般过去时。
三. 延续性动词与瞬间动词[例1] Mr. Green for two hours.A. has goneB. has leftC. has arrivedD. has been away[例2] I for six months.A. have received John’s letterB. have heard from JohnC. haven’t heard from JohnD. haven’t heard from John’s letter以上两题都涉及了延续性动词与非延续性动词,即瞬间动词,所谓延续性动词,又称为持续性动词,即可以表示持久动作或状态的动词,如drink, eat, read, play, fly, talk等词,这些动词有以下特点:(1)可以和表示时间段的状语连用The students have played for an hour.Mr. Green has read for about four hours.He will stay there for two weeks.(2)可以用于进行时态I am writing an important letter.It was raining hard when we got off the rain.瞬间动词,也叫终止性动词,暂时性动词或“点动词”,如open / close, leave, e, go, put, arrive, finish, borrow, lend, marry 等动作在极短的瞬间时间内完成的,也就是说该动作一发生即直接转入结束,结果状态,这类词有以下特点:(1)不能和表示一段时间的时间状语连用,试看以下例句:① 我感冒一个星期了。
