现在完成时

现在完成时表示过去发生或已经完成的动作对现在造成的影响或结果,也可表示过去已经开始,一直延续到现在的动作或状态

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

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)

（二）否定式

主语＋助动词have ／has＋not＋过去分词＋其它

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）We have never spoken to a foreigner．我们从来没有和外国人说过话。

（三）一般疑问式

助动词Have ／Has ＋主语＋过去分词＋其它？

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．”也可以用“No，not yet．／No ，never．／No，not even once．”等。实例：

1）—Have you ever made dumplings ？你曾经做过饺子吗？

—Yes ，I have ．是的，我做过。

2）—Has she ever been abroad ？她曾经出过国吗？

—No，never．不，从来没有。

注意：当句中有否定词not ，hardly（几乎不），never的时候，在改为反意疑问句时，附加部分用肯定形式。例如：You have never come to our school ，have you ？你以前从来没有来过我们学校，是吗？

二、现在完成时的用法

（一）现在完成时的用法1：表示过去发生或已经完成的某一动作对现在造成的影响或结果。此时，常与时间副词already（已经），yet（还、已经），just(刚刚、仅仅) ，ever（曾经），never（从不），before（以前）等连用。这几个副词的用法如下：

1．already意为“已经”，通常用于肯定句中，可放在助动词之后，过去分词之前，也可以放在句末。实例：

1）I've already read this book. 我已经读过这本书了。

（“读”这一动作发生在过去，对现在造成的影响是“知道书中的内容”。）

2）I've washed my clothes already．我已经洗了衣服。

（洗衣服的动作已完成，其结果是“衣服冼干净了”。）

注意：在表示吃惊或明知故问等感情色彩时，already也可用于（口语）疑问句中。实例：3）Have you met him already ？你（真的）已经见过他了？

2．yet用在疑问句中意为“已经”，用在否定句中意为“还”，常放在句末。实例：

1）—Has he found his watch yet ？他已经找到他的手表了吗？

—No，not yet．不，还没有。

2）The woman hasn't found her dog yet ．

那位妇女还没有找到她的狗。（没找到狗，心里着急，这就是对现在的影响）

3．just意为“刚刚”，表示行为刚刚过去，常放在助动词与过去分词之间。实例：He has just come back from school ．他刚从学校回来。

4．ever意为“曾经”，用于疑问句或否定句中，放在助动词与过去分词之间。实例：1）Have you ever been to Hong Kong ？你曾去过香港吗？

2）I haven't ever spoken to her．我未曾和她说过话。

5．never意为“从来没有”常与before连用（before要放在句尾，而never多放在助动词与过去分词之间。实例：

I have never travelled by plane before．我以前从来没有乘飞机旅行过。

6．before意为“以前”，指过去不确定的某个时间，总是放在句末，不受句型的限制。实例：1）Have you been to Hainan before ？你以前去过海南吗？

2）I haven't eaten Guangdong food before．我以前没吃过广东菜。

（二）现在完成时用法二2——持续性用法（肯定句，疑问句中谓语动词必须是延续性动词）：表示过去已经开始，持续到现在的动作或状态。此时常与“for ＋一段时间或“since＋过去

的点时间或从句（从句用一般过去时）以及so far（到目前为止）等时间状语连用。

for + 段时间

since +点时间

实例：

1）I've lived here since 1990．自从1990年以来我就住在这里。

= I've lived here since 13 years ago.

= I've lived here for 13 years.

= It is 13 years since I began to live here.

2）I haven't seen him for three years ．我三年没有看见他了。

= I haven't seen him since three years ago

= I haven't seen him since 2000.

= It is 3 years since I saw him last time.

3）Mr Wang has worked in the factory since he came to the city ．

自从到这个城市以来，王先生一直在这家工厂工作。

注意：①在这类句子的肯定句和疑问句中谓语动词必须用延续性动词。短暂性动词由于动作不能持续，故不能与for(达到；累计)或since（自从。。。到现在）引出的时间状语连用。

②对for和since引导的时间状语提问要用How long

1）他入团两年了。

误：He has joined the League for two years．

正：He has been a League member for two years．

2）我买这辆自行车三年了。

误：I have bought this bike for three years．

正：I have had this bike for three years．

2）▲部分短暂性动词与之对应的延续性动词：

短暂性动词延续性动词

die →be dead

borrow →keep

buy/catch →have

get up →be up

come →be in

finish →be over

leaver →be away

open →be open

close →be closed

begin →be on

become interested in →be interested in

有人可能会问：一般过去时和现在完成时所表示的动作都发生在过去，那么这两种时态有什么区别呢？

☆答：①一般过去时与具体的表示过去时间状语如：yesterday连用；强调动作在过去发生，与现在无关。

②现在完成时与自已的特征词连用，强调过去发生的动作对现在的影响或过去开始发生一直持续到现在的动作。

例：He saw the film last night. (过去时，表示他昨晚看过那部电影了，现在不知还要不要再看一次)

He has (ever) seen the film before.（现在\完成时，表时他已看过那部电影，现在不想再看了）

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 month.

（对）I haven't received his letter for almost a month.

现在完成时练习题及答案(精华版)

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. Jim has been in Ireland ______ Monday. 2. Jill has been in Ireland ______ three days. 3. His aunt has lived in Australia ______15 days. 4. Mary is in her office. She has been there ______ 7 o'clock. 5. India has been an independent country ______1974. 6. The bus is late. They've been waiting ______ 20 minutes. 7. Nobody lives in those houses. 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。

一般过去时与现在完成时的用法区别

一般过去时与现在完成时区别专题一、前言：初一下学期同学们学习了一般过去时态的相关知识，即将到来的初二上学期英语学习中，现在完成时是重要的学习内容。本文通过对比一般过去时和现在完成时，对现在完成时进行初步讲解，希望使同学们读新学期的学习有所准备。二、现在完成时 1. 现在完成时的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. 现在完成时的用法现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。 We are good friends.(现在的情况） I knew him in 1997.（过去的动作） We have known each other since 1997. （现在完成时把过去的动作和现在联系起来并着眼于现在）（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 haven't seen her for four years. 我有四年没见到她了。（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。 3.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。

高考英语现在完成时练习题及答案一、单项选择现在完成时 1．All of her time _______ to carrying out a further study on the cause of Alzheimer’s disease since she left school. A．has been devoted B．devoted C．has devoted D．was devoted 【答案】A 【解析】【详解】考查时态。句意：自从她离开学校，她一直致力于对Alzheimer病因的进一步研究。此处since“自从---以来”，引导时间状语从句，从句用一般过去时态，主句用现在完成时态，且be devoted to“致力于---”，故选A。【点睛】 1.since自从---以来（可做介词和连词），和现在完成时态连用。 He has lived here since he came. 自从他来到这里，就一直在这里住着。 2.It is /has been+一段时间+since 主语+一般过去时态+其他。自从做某事有多长时间了。在这个句型中如果从句的动作是终止性动词，则表示从动作开始到现在多长时间了；如果从句的动作是持续性动词，则表示从动作结束到现在多长时间了。It is three years since he joined (终止性动词)the army.他参军有三年了；It is five years since he lived（持续性动词）here.他离开这有五年了。 2．--- Each of the students, working hard at their lessons, ______ the book. --- So have I. A．is reading B．has read C．reading D．reads 【答案】B 【解析】【详解】考查主谓一致和时态。句意：—努力学习的每个学生都阅读了这本书。—我也读了！根据第二句中的助动词have可知前句中也应该使用助动词have/has，主语each of the students 做主语，谓语动词使用单数形式，故B项正确。【点睛】主谓一致主要指“人称”和“数”方面的一致关系。对大多数人来说，往往会在掌握主语和随后的谓语动词之间的一致问题上遇到困难。一般情况下，主谓之间的一致关系由以下三个原则的支配：语法一致原则 (grammatical concord) 意义一致原则 (notional concord) 就近原则(principle of proximity)。“主谓一致”考查内容涉及名词单数或复数做主语、不可数名词做主语、不定代词做主语、并列结构做主语、特殊名词做主语时与谓语动词数的一致等。列举如下用法： 1. 单数名词(代词)，不可数名词做主语时，谓语用单数形式，复数名词(代词)做主语，谓语
