(完整)初中英语语法-现在完成时讲解以及练习题讲义

现在完成时态语法讲解和习题巩固

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have(has)表明事情发生于现在。它和主语的人称、数要保持一致。过去分词在句子中做谓语，说明句子的含义。

2.用法（1）动作发生在过去某个不确定的时间，但对现在有某种影响和结果。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 2011. 他自2011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。

since和for的区别since后接时间点，如8:00，last term, yesterday, 3 days ago

for后接一段时间，表示“长达多久”，如one year, two days, a long time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 ______5 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.

（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。

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, 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 days. 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. She has worked in the factory for 5 year.

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，必须改为相应的延续性动词来表述。

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 years. ×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 years.

They have _____ _____ only for 5 minutes.

现归纳总结一下由非延续性动词到延续性动词的转换：

1.直接用延续性动词

buy– have；catch(get) a cold – have a cold；borrow—keep；become—be；put on-- wear

2.转换成be+名词

join the army – be a soldier；join the Party –be a Party member；go to school– be a student

3转换成be+形容词或副词

die—be dead；finish – be over；begin—be on；leave—be away ；fall sleep – be asleep

close – be closed come to/ go to/arrive at(in)+某地— be in(at) +某地

finish → be over open → be open

4.转换成be+介词短语go to school– be in school ；get up_ be up；

如：He has been a soldier for three years. 他参军三年了。His father has been dead for two years. 他父亲去世二年了。The film has been on for ten minutes .电影已开始十分钟了。

We have already studied English for three years. 我们已经学英语三年了。

4.现在完成时和一般过去时的区别

现在完成时和一般过去时都表示在过去完成的动作。但现在完成时强调的是这一动作与现在的关系。如对现在产生的结果或影响等，而一般过去时只表示动作在过去某一时刻发生，不表示和现在的关系。试比较：

I have lost my new book.我把新书丢了。（现在还未找到）

I lost my new book yesterday.我昨天把新书丢了。（昨天丢的，现在找到与否没说明）

5.几点注意事项

（1）have been(to)与have gone( to)的区别：

have been(to)表示“去过某地（现在已经回来了）”，可用于各人称；have gone(to)表示“去某地了（说话时某人不在当地）”，常用于第三人称，前者可与once ,never, many times等连用，后者则不能。

如：They have been to Beijing twice.他们曾去过北京两次。He has gone to Beijing . 他已经去北京了。

（2）如单纯表示一段时间，或强调一段时间，虽有since一词，也不必用完成时。

如：It is two years since his father died. = His father has been dead for two years.他父亲去世已有三年了。

英语语法-现在完成时用法及习题

目录 1现在完成时的构成 (2) 2现在完成时的用法 (5) 3 使用现在完成时需注意事项 (7) 4过去完成时与现在完成时的比较 (12) 练习题 (13) 答案 (16)

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.

(窗户现在是坏的) I have already lost the key. (我现在没有钥匙) I haven’t read that book yet . (不了解书的内容) I have just cleaned my hands. (手是干净的) 此时，现在完成时常与already(已经), yet(已经), just(刚刚),ever(曾经)等词连用，通常放在助动词之后，过去分词之前。 already: 常用于肯定句中. yet: 用于否定句，翻译为还没。疑问句尾.翻译为已经 1.你已经找到你的书了吗? 2.他们在这个城市建了许多房子. 3.Judy还没到达.

【英语】初中英语过去完成时试题(有答案和解析)及解析 一、初中英语过去完成时 1．——Jim, did you take out the trash just now? ——No. By the time I came home it . A. have been taken out B. had taken out C. had been taken out 【答案】 C 【解析】【分析】take out拿出，带出，by the time直到，came home是过去时，扔垃圾是发生在came之前的动作，过去完成时表示的是过去的过去。又有be+动词过去分词构成被动语态。had been+过去分词，含有被动语态的过去完成时。句意：Jim，刚才是你把垃圾扔了吗？不，我回来的时候垃圾已经被扔了。故选C。 【点评】考查被动语态及过去完成时的用法。 2．—Peter, _______ you _______ your homework? —Not yet, I'll do it at once. A. have; finished B. Did; finish C. Will; finish 【答案】 A 【解析】【分析】句意：——皮特，你完成作业了吗？——还没有，我马上做。根据Not yet, I'll do it at once.可知此处问你的作业完成了吗，所以句子时态用现在完成时，现在完成时的结构have+done，故选A。 【点评】此题考查句子时态。要根据上下文的联系确定句子时态。 3．Jake _____his key in the office so he had to wait until his wife _______ home. A. has forgotten … comes B. forgot… come C. had left… came D. had left…would come 【答案】 C 【解析】【分析】句意：杰克把他的钥匙丢在办公室了，因此他不得不等到他的妻子回家。结合语境可知前文描述的是过去某时前已经完成的动作，故用过去完成时态。下文指的是过去某时的动作，故用一般过去时态。选C。 【点评】英语中的时态主要是借助于时间状语与上下文语境来进行判断。解答此类题型，首先要注意句子中的时间状语，如果没有则要通过分析上下文，结合语境来判断句子的时态。 4．By the end of 2012, many buildings built in our city.

现在完成时语法详细讲解

英语现在完成时语法详细讲解与配套习题 一、现在完成时用来表示之前已发生或完成的动作或状态，但它的影响现在还存在；也可表示持续到现在的动作或状态。其构成： have (has) +过去分词。规则变化的过去分词与过去式的变化一样，在动词词尾加ed; 不规则变化的过去分词见不规则动词表，需要同学记忆。 现以see the film为例将现在完成时的肯定句，否定句和疑问句列表如下： 肯定句：I/You/We/They have seen the film. He/She /It has seen the film. 否定句：I/You/We/They have not/ haven’t seen the film. He/ She/It has not/hasn’t seen the film. 疑问句：Have I/you/they seen the film Yes, you/ we/I/they have. No, you/ we/I/they haven’t. Has he/she/it seen the film Yes, he/ she/ it has. No, he/ s he/ it hasn’t. 二、用法：现在完成时既涉及过去，又联系现在。 标志词词义用法位置 already已经肯定句句中或句末 ever曾经疑问句、肯定句句中 never从未，从来不陈述句，不和not 连用句中 (ever)since自从肯定、疑问、否定句中 for后接一段时间肯定、疑问、否定句中 just刚刚，正好肯定句句中 yet还疑问句、否定句末 recently最近肯定、否定、疑问句句末 once, twice, a few times几次肯定、疑问句末 during/over /in 在过去的一段时间里肯定、疑问、否定句末 the past/last + 一段时 间 It’s the first time I …这是我第一次…肯定句前

初中英语现在完成时详解

现在完成时 一、现在完成时构成 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、疑问式和简单回答形式如下： 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.

①for+时段 ②since+过去一个时间点（译为：自从……以来） ③since+时段+ago ④since+从句（过去时） ⑤It is+时段+since+从句（过去时） Mary has been ill?for three days. I have lived here?since 1998. 注意： 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。3、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. × 4、has gone (to),has been (to), has been (in)?的区别 Have/Has gone(to) :去了(现在不在说话现场，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、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。不能与when连用。

初中过去完成时讲解教案资料

过去完成时定义 过去完成时(past perfect)表示在过去某一时间或动作之前已经发生或完成了的动作或状态。它表示句子中描述的动作发生在“过去的过去”。 基本结构 主语+had+过去分词vpp.(done) ①肯定句：主语+had+过去分词. ②否定句：主语+had+not+过去分词. ③一般疑问句：Had+主语+过去分词? 肯定回答：Yes,主语+had. 否定回答：No,主语+had not . ④特殊疑问句：特殊疑问词或词组+一般疑问句（Had+主语+过去分词）？ 基本用法 （1）表示在过去某一时刻或动作以前完成了的动作，也可以说过去的时间关于过去的动作。即“过去的过去”。可以用by, before，by the time +从句等介词短语或一个时间状语从句来表示，也可以用一个表示过去的动作来表示，还可能通过上下文来表示。 例如： By nine o’clock last night, we had got 200 pictures from the spaceship. 到昨晚9点钟，我们已经收到200 张飞船发来的图片。 （2）表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态，常和for, since构成的时间状语连用。 例如： I had been at the bus stop for 20 minutes when a bus finally came. 当车来的时候，我在车站已等了20分钟。 He said he had worked in that factory since 1949. 他说自从1949年以来他就在那家工厂工作。 （3）叙述过去发生的事情，在已叙述了过去发生的事情后，反过来追述或补述以前发生的动作时，常使用过去完成时。 例如： Mr. Smith died yesterday. He had been a good friend of mine. 史密斯先生昨天去世了。他以前是我的好友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知，因为我没有好好学习功课。 （4）在含有定语从句的主从复合句中，如果叙述的是过去的事，先发生的动作常用过去完成时。 例如： I returned the book that I had borrowed. 我已归还了我借的书。 She found the key that she had lost. 她丢失的钥匙找到了。 （5）过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句（或间接引语）中，这时从句中的动作发生在主句表示的过去的动作之前。 例如： He said that he had known her well. 他说他很熟悉她。 I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。 （6）状语从句：在过去不同时间发生的两个动作中，发生在前，用过去完成时；发生在后，用一般过去时。 如when,before,after,as soon as,till/until引导的 例如： When I woke up, it had already stopped raining. 我醒来时雨已停了。 She didn’t go to bed until she had finished her work. 她直到把工作做完之后才睡觉。

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：

He had been a good friend of mine. 史密斯先生昨天去世了。他以前是我的好友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知，因为我没有好好学习功课。 （4）在含有定语从句的主从复合句中，如果叙述的是过去的事，先发生的动作常用过去完成时。例如：I returned the book that I had borrowed. 我已归还了我借的书。 She found the key that she had lost. 她丢失的钥匙找到了。 （5）过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句（或间接引语）中，这时从句中的动作发生在主句表示的过去的动作之前。 例如：He said that he had known her well. 他说他很熟悉她。 I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。 （6）状语从句：在过去不同时间发生的两个动作中，发生在前，用过去完成时；发生在后，用一般过去时。 如when,before,after,as soon as,till/until引导的

新概念第二册语法解析及练习：现在完成时

现在完成时： 1．构成：have / has + 过去分词 2．功能： （1）表示过去所发生的动作对现在的影响或产生的结果。常与yet, just, before, recently, lately（最近）, ever, never等表时间的副词搭配使用。 ?. He hasn't seen her lately. ?. I haven't finished the book yet. （2）表示一个从过去某个时间开始，延续到现在并可能持续下去的动作，常与表示一段时间的时间状语连用。如：so far（迄今为止）, up till now（直到现在）, since, for a long time （很长时间）, up to present（直到现在）, in the past / in the last few years（在过去的几年里）, these days（目前）…… ?. He has worked here for 15 years. ?. I have studied English since I came here. ?. The foreigner has been away from China for a long time. ?. So far, I haven't received a single letter from my brother. （3）某些非延续性动词（即：动作开始便终止的动词），在现在完成时中不能与表示一段时间状语搭配。 黄金要点：I．常见的非延续动词：die, arrive（到达）, join（加入）, leave（离开）, go, refuse （拒绝）, fail（失败）, finish, buy, marry, divorce（离婚）, awake（醒）, buy, borrow, lend ... II．这类动词并非不能用现在完成时，而是不能接常由for引导的时间状语。 III．但若是用在否定句中，非延续动词的现在完成时可以与表示一段时间的状语连用。?. She has gone away for a month.（误）?. She has been away for a month （正） ?. The man has died for two years.（误）?.

现在完成时语法

（Present Perfect）。 第一部分 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。学习现在完成时,先从结构和句式开始: 构成:主语 + have/has + 过去分词 + 其他。(当主语是第三人称单数时用has,其余人称用have。过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。) 否定式:主语+ haven't/hasn't + 过去分词+ 其他。 疑问式: Have /Has + 主语+ 过去分词+ 其他? 简略答语: Yes, 主语+ have/has.(肯定) No, 主语+ haven't/hasn't.(否定) 现在完成时常用的时间状语有： already （”已经”用于肯定句的中间和末尾处） never (“从不”用于中间处) ever （”曾经”用于疑问句和肯定句的中间处） just (“刚刚”用于中间处) yet (“已经”用于疑问句的末尾处/ “还”用于否定句的末尾处) 或不加任何的时间状语，但不能和表示过去的时间状语连用. 第二部分 现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义: * 以already, just和yet为标志 already, just和yet 表示到现在为止动作或状态已经、刚刚或还没有发生。 He has already got her help. 他已得到她的帮助。 He has just seen the film. 他刚刚看过这场电影。 He hasn't come back yet. 他还没有回来。 * 以ever和never为标志 ever和never 表示到现在为止动作或状态曾经或从来没有发生过。 This is the best film I have ever seen. 这是我曾经看过的最好的一部电影。 He has never been to Beijing. 他从没有到过北京。 * 以动作发生的次数为标志 若某一动作到现在为止已经发生了若干次,则要使用现在完成时。 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为标志 so far往往表示到目前为止动作或状态已经发生。 He has got to Beijing so far. 到目前为止他已到了北京。 She has passed the examso far. 到目前为止她已经通过了。 第三部分 过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时。 *“终止”、“延续”要转换

(完整word)初中过去完成时讲解

过去完成时用法讲解 一、概念：表示过去的过去，其构成是had +过去分词。 二、用法： 1. 表示某一动作在过去某一时刻之前已完成。例如: He had gone to bed by 10:00 last night. (昨夜十点钟之前他已上床去睡了。) 2. 与一般过去时搭配，表达某一动作在过去的动作发生时已完成。例如： The train had started when I got to the station. (当我到达车站时火车已开走了。) The minute I saw a lady getting off the bus, I knew it was she, for I had seen her before. (我一看到正在下公共汽车的那位女士就知道是她，因为我以前看见过她。) 解说：使用过去完成时在简单句里表达某一动作在过去的某一时刻已完成时，该过去的时刻常以“by +过去时间”的短语来表达。例如下面的说法是不正确的： He had gone to bed at 10:00 last night. 若是要说“at 10:00 last night”就必须用一般过去时“He went to bed...”。请再观察下面的句子试比较：It had rained yesterday. (误) It rained yesterday.(正) 或许你会说：“昨天下了雨，可是今天已放晴了，下雨已是过去的事，而且已经下完了，所以就用过去完成时……。”这就是最令同学们对一般过去时和过去完成时感到混淆和困惑的。实际上只要我们了解下面的两点原则就可以消除这种现象。 1. 由过去的时间作状语来修饰动词的句子都使用一般过去时。 2. 除非从谈话的先后关系和上下文关系对过去的动作完成的基准点可以确定以外，应该避免在简单句中使用过去完成时。 三、过去完成时常用的连词有：before, by, until, when, after, once, as soon as等。例如： He said that he had learned some English before. By the time he was twelve, Edison had began to make a living by himself. Tom was disappointed that most of the guests had left when he arrived at the party. 四、在什么情况下使用过去完成时？ 1. 在told, said, knew, heard, thought等动词引导的宾语从句中，一般用过去完成时。例如： She said (that) she had never been to Paris. 2. 状语从句 在过去不同时间发生的两个动作中，发生在先，用过去完成时；发生在后，用一般过去时。例如：When the police arrived, the thieves had run away. 3. 表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示“原本……，未能……”。例如： We had hoped that you would come, but you didn't. 典型例题： The students ________ busily when Miss Brown went to get a book she ____ in the office. A. had written, left B. were writing, has left C. had written, had left D. were writing, had left 答案D。“把书忘在办公室”发生在“去取书”这一过去的动作之前，因此“忘了书”这一动作发生在过去的过去，用过去完成时。句中when代表时间的一点，表示在“同学们正忙于……”这一背景下，when所引导的动作正在发生。因此前一句应用过去进行时。 初中英语语法梳理和提高14过去完成时态讲解试题 过去完成时态
