一.现在完成时的含义及用法 1.现在完成时表示过去发生的动作,并对现在有影响。 2.现在完成时表示从过去一直持续到现在的动作或状态。 现在完成时的基本句型： 肯定式： 主语 + 助动词have/has + 动词的过去分词. 否定式: 主语 + 助动词have/has + not + 动词的过去分词. 疑问式： 助动词Have/Has + 主语 + 动词的过去分词? 用法①现在完成时表示过去发生的动作,并对现在有影响。 Someone has broken the window. (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.
4.你吃过早饭了吗? 用法② 现在完成时表示从过去一直持续到现在的动作或状态。 She has learned English for 5 years. He has lived in Beijing since ( 自从)he was born . Have you stayed here since ( 自从) 3 o’clock? for+ 时间段 since+时间点 , since+ 句子 ①Mr. Brown has had his TV _____15 years. ②I’ve taken driving lessons _______last month. ③My sister has had her cell phone _____a month . ④My friends haven’t visited me _______ my birthday. ⑤We haven’t used our car _____a long ti me . ⑥She hasn’t had a good cup of coffee ____ years. ⑦Tom has worn glasses _______he was 7 years old. 二.have been 与have gone 的用法比较 have been to “到过，去过”，表示曾经到过某处，但现在人不在那儿。 have gone to“去了”，表示已经去了某地，现在人可能在去的途中或已在那儿了。 have been in“呆在某处一段时间了” 三.实义动词分为: 瞬间动词、延续动词
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。
现在完成时的基本用法
现在完成时讲解与练习 （一）现在完成时的基本用法 （1）强调动作是从过去持续到现在，并有可能继续持续下去。 （2）强调对现在的影响或结果，此用法容易和一般过去时混淆。两者的区别是：一般过去时有动作发生的时间点，即过去某一时间发生某一动作；现在完成时则没有，即不强调是哪个时间点发生的动作，而强调过去的动作对现在造成的影响和结果。 （3）在过去不确定的时间里发生的动作，但是结果对现在有影响。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 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：

现在完成时练习题及答案
现在完成时 一、其构成 "助动词have (has) +动词过去分词"构成现在完成时。如： 1. Kate's never seen Chinese films，____ ? A. hasn't she B. has she C. isn't she D. is she 析：陈述句部分含否定词never,简略问句部分要用肯定式，又因Kate's是Kate has的缩写，故选B。 2. His uncle has already posted the photos to him. (改为否定句) His uncle ______ posted the photos to him ______. 析：already常用在肯定句中，yet常用在否定句、疑问句中，故填hasn't, yet。 3. -Ann has gone to Shanghai. -So ______her parents. A. has B. had C. did D. have 析："so+助/系/情态动词+主语"结构中的动词形式应与前句结构中动词形式保持一致，又后句的主语为her parents是复数,故选D。 二、其用法与标志词 (一)当句中有never, ever, just, already, yet, before等时，常用现在完成时。如： 1. -Mum, may I go out and play basketball? -___________ your homework yet? A. Do; finish B. Are; finishing C. Did; finish D. Have; finished 2. -______ you ______anywhere before? -Yes, but I can't remember where I______ A. Did; surf; surfed B. Have; surfed; surfed C.

His brother has been to Stone Forest twice______he came to Yunnan. A. after B. before C. since D. for 析：主句用的是现在完成时，而从句用的是一般过去时，故选C。 2. Tom______the CD player for two weeks. A. has lent B. has borrowed C. has bought D. has had 析：A、B、C均为非延续性动词，在肯定句中不与表"段时间"的短语连用，故选D。3. I______a letter from him since he left. A. didn't receive B. haven't got C. didn't have D. haven't heard 析：据since可知，应排除A、C，"hear from sb.=receive/get/have a letter from sb."意为"收到某人的来信"，故选B。 三、have/has been (to, in)/have/has gone (to)的区别。如： 1. -Have you ever______Lintong to see the Terra Cotta Warriors?-Yes, I have. A. went to B. gone to C. been in D. been to 析：据句中的have，排除A，B项意为"去某地了"，C项意为"一直呆在某地"，D项意为"去过某地"，符合题意，故选D。 2. My parents ______ Shangdong for ten years. A. have been in B. have been to C. have gone to D. have been 析：本题句中有"for+段时间"结构，据此可排除C，B项意为"去过某地"，不合题意，D项缺介词，故选A。 四、现在完成时与其他时态的联系和区别。如： 1. Sun's aunt has gone there for ten years.(改成正确的句子) 析：非延续性动词与"段时间"连用时，除了把非延续性动词改成延续性动词外，还可把动词改为一般过去时或借助句型"It's +段时间+since+从句"进行句子转换。故答案为：Sun's aunt has been there for ten years. /Sun's aunt went there ten years ago. /It's ten years since Sun's aunt went there. 2. Susan has been in this city for more than ten years.(改为同义句) ________more than ten years ____Susan ______to this city. 析：据上题分析，且since引导的从句要用一般过去时，故填It is, since, came。 3. I won't go to the concert because I ____my ticket. A. lost B. don't lose C. have lost D. is coming 析：因我丢了票的动作发生在过去，而且对现在造成了我不能参加音乐会的结果，符合现在完成时所表示的含意，故选C。 一、单项选择 1、Both his parents look sad. Maybe they _______what’s happened to him . Ａ. knew Ｂ. have known Ｃ. must know Ｄ. will know 2、He has _______ been to Shanghai, has he?

专项语法讲练——现在完成时 【概念引入】 如何学习时态？对中学生来说，最好还是从各个时态的基本概念、基本形式和基本用法学起。在过了这一阶段之后，再放开步伐，通过大量的听、读和笔头实践，获得感性的知识。现在，我们就从最基本的概念、形式和用法等方面来总结一种新的时态——现在完成时。 【用法讲解】 一、现在完成时的定义 现在完成时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。 二、现在完成时的构成 1. 肯定句 现在完成时的肯定句式是“have（has）＋过去分词”。 注意：该句式中的have或has是助动词，has用于第三人称单数，其它人称一律用have。 2. 否定句： 现在完成时的否定句式是“haven’t（hasn’t）＋过去分词”。 3. 疑问句： 现在完成时的一般疑问句式是把助动词have或has提到主语之前。回答用Yes, …have(has)./ No, …haven’t(hasn’t). 三、动词过去分词规则变化与不规则变化 (一) 规则变化 变化规则：与动词过去式规则相同。 1. 一般直接在词尾加上ed。look —looked 2. 以e结尾的动词，直接加d。move —moved 3. 以y结尾，y前面是辅音字母的动词，变y 为i，再加ed。carry —carried 4. 部分动词需双写尾字母，加ed。stop —stopped (二)不规则变化 不规则动词的变化因词而异。但是如果对不规则动词的过去式和过去分词做一分析，就可发现其中的“规则”。同学们在记忆时，可按下面的形式对教材后不规则动词表进行分析、整理。例如：AAB型 ABC 型 AAA型

I have lived here since 1998. 注（超重要）：瞬间动词（buy,die,join,lose……）不能直接与for since 连用。要改变动词 come-be go out-be out finish-be over open-be open die-be dead 1.have代替buy My brother has had(不能用has bought) this bike for almost four years. 2、用keep或have代替borrow I have kept(不能用have borrowed) the book for quite a few days. 3、用be替代become How long has your sister been a teacher? 4、用have a cold代替catch a cold Tom has had a cold since the day before yesterday. 5、用wear代替put on b)用“be＋形容词”代终止性动词 1、be＋married代marry 2、be＋ill代fall (get) ill 3、be＋dead代die 4、be＋asleep代fall (get) asleep 5、be＋awake代wake/wake up 6、be＋gone代lose,die,sell,leave 7、be＋open代open 8、be closed代close/shut 9、be＋missing(gone,lost)代lose c)用“be＋副词”代终止性动词 1“be＋on”代start,begin 2“be＋up”代get up 3“be＋back(to)”代return to,come back to,go back to 4“be here (there)”代come(arrive,reach,get) here或go (arrive,reach,get) there等等
现在完成时练习题及答案
一、时态讲解：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： a)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. 1. since 2. for 3. for 4. since 5. since 6. for 7. for 8. since 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 2）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）. 3）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。They have never been to Yan’an. 他们从未去过延安。 I haven't seen him lately. 我近来没看到他。 Exercise: I. Fill in the blanks with the proper form. 1. I____ already ____ (see) the film. I ________ (see) it last week.
