现在完成时的结构
现在完成时的结构现在完成时由“ have/has+过去分词”构成，主要有两个含义：①表示动作发生在过去，但与现在的情况有联系，有时无时间状语，有时和一些表示不确定的过去时间状语连用，如：many times，just ，yet，ever，never，already ，before，so far, by now 等连用。
②表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作，用于延续性动词，且句中常带有表示一段时间的时间状语，如：since +时间点/从
句, for two mon ths, so far 等。
二、1）现在完成时和一般过去时都能表示过去发生过的动作，但现在完成时表示过去动作对现在的影响，并且表示这一动作已完成或还可能继续下去；2）而一般过去时与现在的情况没有联系，仅表示过去的动作，且这一动作到说话时已
终止。因此现在完成时不能与表示明确的过去时间如:in 1949 , yesterday ，last week等的状语连用，并且用when或where对这些时间和地点状语提问时，一般只用一般过去时。
三、在“ it is first/second ...time that... 。” 或在“ it/this/that is the
+最高级+名词+that...。”结构中，that从句中的动词常用现在完成时；在“it +
be ...+si nee 从句”这一结构中，be可用一般现在时或现在完成时，since 从句一般用过去时。have/has/had +been +动词的现在进行时
比较过去时与现在完成时
1）
过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在 _____ 成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。
2）过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。一般过去时的时间状语：
yesterday, last week ，,ago, in1980, just now, 具体的时间状语
共同的时间状语：
this morning, tonight, this April, now, onee，before, already, reeently ，lately
现在完成时的时间状语
for, sin ee, so far, ever, n ever, just, yet, till / un til, up to now, in past years, always,
不确定的时间状语
3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, lear n, work, study, know.
过去时常用的非持续性动词有come, go, leave, start, die, fini sh, become, get married 等。
举例：
I saw this film yesterday.
（强调看的动作发生过了。）
I have see n this film.
（强调对现在的影响，电影的内容已经知道了。）
Why did you get up so early?
（强调起床的动作已发生过了。）
Who has n't han ded in his paper?
（强调有卷子，可能为不公平竞争。）
She has returned from Paris.
她已从巴黎回来了。
She retur ned yesterday.
她是昨天回来了。
He has bee n in the League for three years.
（在团内的状态可延续）
He has bee n a League member for three years.
（是团员的状态可持续）
He joined the League three years ago.
（三年前入团，joined为短暂行为。）
I have fini shed my homework now.
---Will somebody go and get Dr. White?
---He's already been sent for.
句子中如有过去时的时间副词（如yesterday, last, week, in 1960 ）时，不能使用现在完成时，要用过去时。
（错）Tom has written a letter to his parents last night.
（对）Tom wrote a letter to his parents last night.
用于现在完成时的句型
1）It is the first / second time,. that, 结构中的从句部分，用现在完成时。
It is the first time that I have visited the city.
It was the third time that the boy had been late.
2）T his is the, that, 结构，that从句要用现在完成时.
This is the best film that「ve （ever） see n.
这是我看过的最好的电影。
This is the first time （that） I've heard him si ng. 这是我第一次听他唱歌。典型例题
⑴---Do you know our tow n at all?
---No, this is the first time I __ here.
A. was
B. have bee n
C. came
D. am coming
答案B. This is the first time 后面所加从句应为现在完成时，故选B。（2） ---Have you _ bee n to our tow n before?
---No, it's the first time I ___ h ere.
A. eve n, come
B. eve n, have come
C. ever, come
D. ever, have come
答案D. ever意为曾经或无论何时，反意词为never，此两词常用于完成时。This is the largest fish I have ever seen. It is / was the first time
+that-clause 的句型中，从句要用完成时。
注意：非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
（错）I have received his letter for a mon th.
（对）I have n't received his letter for almost a mon th. 比较since和for
Since用来说明动作起始时间，for用来说明动作延续时间长度。
I have lived here for more tha n twenty years.
I have lived here since I was born..
My aunt has worked in a clinic since 1949.
Some new oilfields have bee n ope ned up since 1976.
I have known Xiao Li since she was a little girl.
My brother has bee n in the Youth League for two years.
I have not heard from my uncle for a long time.
注意：并非有for作为时间状语的句子都用现在完成时。
I worked here for more tha n twenty years.
（我现在已不在这里工作。）
I have worked here for many years.
（现在我仍在这里工作。）
小窍门：当现在完成时+—段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。
1）（对）Tom has studied Russian for three years.
=Tom began to study Russian three years ago, and is still studying it
now.
2）（错）Harry has got married for six years.
=Harry began to get married six years ago, and is still getting married
now.
显然，第二句不对，它应改为Harry got married six years ago.或Harry has bee n married for six years.
编辑本段since的四种用法
1）since +过去一个时间点（如具体的年、月、日期、钟点、1980, last mo nth, half past six）。
I have bee n here since 1989.
2）since + 一段时间+ ago
I have bee n here since five mon ths ago.
3）si nee + 从句
Great cha nges have take n place since you left.
Con siderable time has elapsed since we have bee n here.
4）It is + 一段时间+ since从句
It is two years since I became a postgraduate stude nt.
延续动词与瞬间动词
1）用于完成时的区别
延续动词表示经验、经历；瞬间动词表示行为的结果，不能与表示段的时间状语连用。
He has completed the work. 他已完成了那项工作。（表结果）
I've kn ow n him si nee the n. 我从那时起就认识他了。（表经历）
2）用于till / until 从句的差异
作为延续动词一般用于肯定句，表示"做,,直到,,"作为瞬间动词一般用于否定句，表示"到”，才,,"
He did n't come back un til ten o'clock.
他到10点才回来。
He slept tll ten o'clock.
他一直睡到10点。
典型例题
1. You don't n eed to describe her. I __ her several times.
A. had met
B. have met
C. met
D. meet
答案B.首先本题后句强调对现在的影响，我知道她的模样，你不用描述。再次, several times 告知为反复发生的动作，因此用现在完成时。
2. ---I'm sorry to keep you wait ing.
---Oh, not at all. I ___ here only a few minu tes.
A. have bee n
B. had bee n
C. was
D. will be
答案A.等待的动作由过去开始，持续到现在，应用现在完成时。

现在完成时对于我们来讲是所有时态中最难掌握的一种。因为它并不是表示发生于某一时间的事情，而是既涉及过去，又联系现在的一种时态。请参见下列三个例句： 例：1.I live in Beijing. 我住在北京。 2.I lived in Beijing. 我住过北京。（我在北京住过。） 3.I have lived in Beijing. 我一直住在北京。 例1.的live是一般现在式，表示“我现在住在北京”这一事实。 例2.的lived是过去式。这句只是表示在过去的某一时期我在北京住过，至于现在住不住在北京则不清楚。 例3.的have lived是现在完成时，表示我在过去的某一时间开始住在北京，现在也住在北京。表示从过去到现在的一种继续状态。 1现在完成时的构成 现在完成时的形式是“have （has）+过去分词”，表示继续、完了、结果和经验等四种意思。 现在完成时的否定句是在have（has）的后面加上not，疑问句是将have（has）置于主语之前。 1现在完成时的肯定句 句型：
We have lived in Beijing. 我们一直住在北京。 He has lived in Beijing. 他一直住在北京。 过去分词的三种用法 过去分词有下列三种用法（过去分词的构成详见第六章）：1.构成现在（过去）完成时 have（has）+过去分词～ I have written the letter. 我写完这封信了。 2.被动语态：参见第十三章 be + 过去分词～ He was looked after.他受到照顾。 3.用于形容词 This is a broken chair. 这是一张坏的椅子。 2现在完成时的否定句 句型：主语+have（has）+not +过去分词～. I have not seen the movie yet.

现在完成时练习题及答案精华版.doc
现在完成时 （1）构成：现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化。第三人称单数用has，其余用have. 现在完成时的否定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，其否定式、 1）现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。 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）表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，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. 最近我们没有见到你。 They have been away for two years. 他们离开已经两年了。She has been with us since Monday. ★注意： 1）since和for的区别 since后接时间点，如1993，last term, yesterday, the time I got there for后接一段时间，表示“长达多久”，如ten years, a while, two days等。 Exercise: 用since和for填空 1.

They have been empty ______ many years. 8. Mike has been ill ______a long time. He has been in hospital ______ October. 2）表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等，在完成时当中不能和表示一段时间的状语连用，因为它们表示的动作不可能持续。因此，不能说： He has come here for 2 weeks. × The old man has died for 4 months. × They have left only for 5 minutes. × 以上三句话可以改为： He has been here for 2 weeks. The old man has ______ _______ for 4 months. They have _____ _____ only for 5 minutes. 3）have (has) been 和have (has) gone的区别：表示“曾到过某地”要用“have (has) been”; 表示“已经去某地”要用“have (has) gone”。试比较： Where has he been? 他刚才到哪里去了？（已经回来了） Where has he gone? 他上哪儿去了？（人不在） They have been to Canada. 他们到过加拿大。（现在已经不在加拿大） They have gone to Canada. 他们到加拿大去了。（可能在路上和已经到加拿大）. 4）现在完成时不能和表示过去的时间状语连用，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。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. 马红一直是个好学生。I have often seen him in the street. 我经常在街上看见他。
现在完成时的构成英语语法大全
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 books ．她丢失了她的书。（表示到目前为止还没有找到） (如果用过去时：She lost her books . 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＋过去分词＋其它 说明：现在完成时构成否定句时，只需在助动词have ／has后面加not就行。have not，has not的缩略式分别为haven't ，hasn't。另外，肯定句中有some，already时，改为否定时要分 别改成any，yet。实例： 1）I haven't finished my homework yet．我还没有完成我的作业。 2）She hasn't travelled on a train ．她没有坐火车旅行过。 3）We have never spoken to a foreigner．我们从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。 三）一般疑问式 助动词Have ／Has ＋主语＋过去分词＋其它？ 说明：把陈述句中的have或has放到句首，句末打问号，同时把句中的some ，already改为any ，ye t就构成了一般疑问句。肯定回答用“Yes ，主语＋have／has．否定回答用“No，主语＋haven't／hasn't．”有时也可以用“No，not yet．／No ，never．／No，not even once．”等。实例：
