现在完成时态
（一）定义：两种情况
1>表示过去发生或已经完成的某一动作对现在造成的结果或影响
2>从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，将来还有可能继续下去。
（二）基本结构：主语+have/has+过去分词(done)
PS:根据主语的单复数来确定助动词是选用have还是has.
①肯定句：1>主语+have/has+done…….
2>主语+have/has+been+doing……这是现在完成进行
时同样插在现在完成时态这里，也是提到主要的
用法，特别地它带有一些感情色彩如激动、抱
怨……
Eg: I have trained 80 students I joined the education institution(教育机构)
译：在过去的两个小时里，他一直在调试设备。（暗含着现在还在调试，还有可能继续下去）调试的动词原形：debug
②否定结构：主语+haven’t / hasn’t + done +……
③一般疑问句中：Have/Has+主语+ done+……?
肯定回答：Yes,主语+have/has.
否定回答：No,主语+have/has not .
Eg: Have you ever been to an amusement park?
肯定回答：Yes, I have .
否定回答：No, I haven’t.
注意：have /has been to + 地点：去过某地（已回），表示“到(去)过某处”，现在已不在那个地方。在谈起自己曾经去过某个地方时，可以用到。区别于：have/has gone to + 地点：去了某地（未回），表示“去/到了某处”
Eg: Has she gone to Hongkong ?
译：她已经去香港了吗？(已到达香港还未回来或者在去香港的路上) 上述的have/has been to和have/has gone to可以用来表达自己平常出差的一种状态。
特殊疑问句：特殊疑问词（What/Why/Who/…）+have/has+主语+done……？
（三）具体用法
1）过去发生的动作对现在产生的影响或结果，或说话时已完成的动作。常见的状语有：now，already, yet, ever(曾经), ever since（自那时起），never, till / until, this week /month/year，many times 等包括现在时间在内的状语。
Eg：I have been over my English study plan now.（be over 代替了finish）Eg: I think that the problem is that I haven't (yet ) figured out what I want.划线句子做整个句子的宾语从句，句子的结构比较复杂，仔细分析译：我认为问题就是我还没有弄清楚自己要的是什么
Eg: What's the best gift you have ever received? 定语从句修饰gift
Eg: The shop has been open ever since.
Eg: We should say that we so excellent a film as The
译：我们必须承认在此之前我们从未看过像《暮光之城》这样棒的电影.
Eg:Until you tell me the thing completely now, I have mastered all of it.译：直到你现在完整地告诉我这件事，我才掌握了全部的情况。Eg: This is the third time that I have been to the clinic(诊所) this week. 2）表示从过去开始的动作或状态一直持续到现在，常用for和since 后接表示一段时间的状语，so far(到目前为止)，up to now(到现在为止), in/over the past/few /数词years(在过去的几年里)
Eg: I have taught the course for one and half an hour .
译：我已经讲了一个半小时的课了。teach-taught- taught
Eg: Mark has worked here since he left college.
Eg: We' ve only raised 2000 dollars so far, but we're still 500 short of the amount we need. be short of 缺少……
译：到现在为止我们已经筹集了2000元，但是离我们所需的数目仍然还差500元。
Eg:I have travelled eleven provinces up to now.
译：到现在为止我已经游历了十一个省份。
Eg: Great changes have taken place in my hometown in the past few years.
译：在过去的几年时间里我的家乡发生了巨大的变化。（这是常用句）3）在时间状语从句、条件状语从句中表达将来某时已经完成的动作。Eg: When you have learned English, you will find it a bridge to so much knowledge .Because the limits of your language are the limits of your world.
译：当你学会英语之后，你将找到一条通往丰富知识的桥梁。因为你语言的边界就是你人生的边界。
We’ll start at six if it has stopped raining by then.
译：如果那时雨已经停了，我们就在六点出发
4）下列句型中常用完成时态：
<1>This is the first/second/third……+time +that 从句
that 从句的谓语要用现在完成时，译为：这是…第几次做某事
（这一块有关时态的问题和过去完成时有交叉，怕给你看混了，以后会给你分开他们的区别）
Eg: This is the second time that I have published an article in the newspaper.
译：这已经是我第二次在该报纸上发表文章
<2>It is 一段时间+since从句(过去完成时)
has been
Eg: It has been thirteen years since Jolin and Jay Chou broke up.

Eg: It has been two years since my brother joined the army. 参军
<3> This is the best/finest/most interesting 等形容词最高级+that+从句（现在完成时）
Eg: This is the stable marketing channel that I have been in charge of the area. be in charge of …… 负责/执掌/管理…… 译：这是我负责的这个地区最为稳定的销售渠道。
N N o o w w c c o o m m e e s s y y o o u u r r t t u u r r n n t t o o e e x x a a m m i i n n e e y y o o u u r r s s e e l l f f …………

附件一：在完成时态中，常见瞬间动词（非延续性动词）的替换单词表
首先注意：表过去某一时间发生的动作或状态一直延续到现在（强调现在），动作或状态一般是延续性的，因此要用表延续性的动词或表状态的动词。
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，即不能用于完成时也不能用于how long引导的疑问句中（how long对一段时间提问）。Eg: He has borrowed the book for two months.(误)
borrow一旦借出动作立马终止，所以不能用在完成时态。
Eg: He has kept the book for 2 months. （正）keep可以保存一段时间简单的提一下，非延续性动词在否定结构中可用于现在完成时态：I haven’t bought anything for two days.（有了解就可以）
现在完成时专题 1.用法：①过去发生的动作对现在造成的影响或结果，强调结果。标志性的词语有just, already, before, yet, never, ever,recently （最近），... 例：I have finished my homework already. ②过去已经开始一直持续到现在的动作或状态。标志性的词语for 、since ，so far （句中谓语动词要用延续性动词） 例：I have lived here since 1990. 2.现在完成时的构成 主语+have\has+过去分词+其它 3.现在完成时的四个基本句型 （1）九词语 ①already 已经 肯定句中或句尾 例: I have already found my pen. = I have found my pen already. ②yet 否定句中意为“还”， 疑问句句尾意为“已经” 例： I have not finished the work yet. Have you read the book yet? ③ever 曾经 例：Have you ever seen pandas? ④never 从不 例：I have never been to Beijing. ⑤just 刚刚 例：I have just done my work. ⑥before 以前 例：I have never been there before. ⑦so far 到目前为止 例：So far he has learnt 200 words. ⑧how long 多久 例：How long have you lived here? ⑨how many times 多少次 例：How many times has he been to Beijing? （2）三词组 have
现在完成时讲解与练习 1.构成现在完成时是由助动词 have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和 主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。 2.用法 （1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。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．结构 1）．陈述句结构：主语＋have( has)（not）+过去分词＋其它。have not=h aven’t has not=hasn’t. 2）．一般疑问句结构：Have( Has )＋主语＋过去分词＋其它 3）．特殊疑问句：特殊疑问词＋have(has) +主语+ 过去分词＋其它 eg. He has already finished his homework. He hasn’t finished his homework yet. Has he finished his homework yet --Yes, he has./ No, he hasn’t./ No, not yet. （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。 4.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。多用于否定或疑问句中，表示“曾经”或“从未“等。如 -Have you ever been to the Great Wall你曾经去过长城吗 -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语，如just, before, up to now, the past few years等。例如： I have seen her before, but I can not remember where.我以前见过她，但记不起在哪里见过。 He has been there three times the last few years.近几年他去过那里三次了。 d.用包括“现在”在内的时间状语，如：now, today, this morning (month ,year, term)等。例如 -Have you met him today-No,I haven't.今天你见过他吗我没有。 How many times have you been there this year 今年你去过那里多少次 （2）现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始， 一直持续到现在。如：I haven't seen him for two years. 但是，像come, arrive, buy等终止性动词不能与 表示“一段时间”的状语连用。要用，必须改为“be（在）”等延续性动词来表述。现归纳总结一下由非延续性动 词到延续性动词的转换： arrive→be here begin(start)→be on die →be dead come back→be back leave →be away fall ill(sick,asleep)→be ill(sick,asleep) get up→be up go out → be out finish →be over put on →wear 或be on open →be open join →be in或 be a member of… close →be closed go to school→be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study→study come to work →work等 如：He has been a soldier for three years.他参军三年了。

语法探知：现在完成时态 一、掌握结构：助动词have/has + 动词的过去分词 二、掌握用法： 1.表示过去发生的某一动作对现在造成的影响或结果，常与一些时间状语，如:already, yet, ever, never, just, before, once, twice （次数）等连用，也可以和包括现在在内的时间状语，如these days, today, recently, this year, so far(=by now)等连用. e.g. I have already posted the letter. (信已经不在我这儿了) 2.表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段，since+时间点/从句, in(during) the last(past) ten years等，谓语只可用延续性动词。 我们知道英语动词根据词义可分为两种,一种是延续性的，一种是终止性的，终止性动词(也可称为非延续性动词,瞬间动词,或短暂性动词),如begin, start, die, buy, leave, come等,表示动作在一瞬间之内就能完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+段时间，since+点时间/从句连用,也不能用在how long引导的特殊疑问句中。（但在否定句中短暂性动词可以与for和since短语连用。） 如：They’ve left London for five days. (×) They’ve been away from London for five days. (√) 三、掌握短暂性动词如何转换成延续性动词 常见短暂性动词与延续性动词的对应关系如下: come/go/arrive/get/reach/move—be in/at open—be open die—be dead close—be closed become—be borrow—keep begin/start—be on put on—wear leave—-be away (from) buy—have fall asleep(ill)—be asleep(ill) end/finish—-be over catch a cold—have a cold join the army—be in the army/ be a soldier join the Party—be in the Party/ be a Party member get to do —do (get to know—know) get married —be married get up —be up begin to do —do (begin to study—study)
