现在完成时讲解和练习
1. 现在完成时的构成: have\has+过去分词 (过去分词的构成有规则变化和不规则变化)
2. 现在完成时的四个基本句型
肯定句 He has finished the work.
一般疑问句 Has he finished the work? 回答 Yes ,he has. No, he hasn’t.
否定句 He has not finished the work.
特殊疑问句 What has he done?
3.现在完成时的用法:
A．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，强调对现在造成的影想或结果）。例如： The car has arrived. 车子来了。（结果：车子已在门口）
Someone has broken the window.有人把窗户打破了。（结果：窗户仍破着）
B. 表示过去已经开始，持续到现在的动作或状态，可以和表示从过去某一时刻延续到现在（包括“现在”在）的一段时间的状语连用,如for+时间段、since+过去的时间点、疑问词how long等。例如：My uncle has worked at this factory for five years. 我叔叔在这个工厂工作已经五年了。
Mr. Black has lived in China since 2002. 自从2002年Mr. Black 一直住在中国。
How long have you been here? 你来这里多久了？
4. 在下列情形下用现在完成时
(1)九词语
①already已经肯定句中或句尾
e.g.: I have already found my pen.
= I have found my pen already.
②yet已经否定句和疑问句句尾
e.g.：I have not finished the work yet. Have you bought a computer yet?
③ever曾经句中
e.g.： Have you ever seen pandas?
④never从不句中
e.g.：I have never been to Beijing. ⑤just刚刚句中
e.g.：I have just done my work.
⑥before以前句尾
e.g.：I have never been there before.
⑦so far到目前为止
e.g.：So far he has learnt 200 words.
⑧how long多久
e.g.：How long have you lived here?
⑨how many times多少次
e.g.：How many times has he been to Beijing?
(3)三词组
1.have
e.g.：He has gone to Beijing (去了)
2.have
e.g.：He has been to Beijing. (去过)
3.have
e.g.: Mr. Brown has been in Beijing for three days. 布朗先生来已经有三天了
4.如果句子里面没有时间状语，汉语意思能够加“已经”，往往用现在完成时态。
e.g.：Have you lost your library book? 你已经弄丢了从图书馆借的那本书吗？
5.现在完成时态还常常用于下列句型
This is the best book I have ever read. 这是我曾经读过的最好的一本书。
It is the first time I have played the computer games. 这是我第一次玩电脑游戏。
6.在现在完成时中，瞬间动词不能和一段时间状语连用
e.g.：He has bought the book for 3 years.（错）
因buy这个一次性动词不能和一段时间for 3 years连用, 改正的办法有五种：
① He has bought the book.. (去掉一段时间for 3 years)
② He bought the book 3 years ago (改为一般过去时，使句子的意思不变)
③It’s 3 years since he bought the book. = 3 years has passed since he bought the book.
（改为固定句型 It is ---since---）
④ He has not bought the book for 3 years.（改为否定句）
⑤ He has had the book for 3 years. （用延续性动词have代替buy）
7. 还有其他瞬间动词也是这种情况，可参照前面的五种办法改正，前四种改法都一样，第五种改法各不
相同，举例如下：
①come/arrive/get to/reach → be here
e.g：I have come here for 3 years.（错）改为：I have been here for 3 years.
②leave/go →be away
e.g.：He has left for 3 hours.（错）改为：He has been away for 3 hours.
③begin/start →be on
e.g.：The film has begun for 3 minutes.（错）改为：The film has been on for 3 minutes.
④open →be open / close → be closed
e.g.：The shop has opened for 3 years.(错) 改为：The shop has been open for 3 years.
⑤die →be dead
e.g.：His father has died for 3 years.(错) 改为：His father has been dead for 3 years.
⑥finish/end→ be over
例：He has finished the work for 3 days.(错) 改为：The work has been over for 3
days
⑦join例：I have joined the army for 3 years.（错）
改为：I have been in the army for 3 years. 或I have been a soldier for 3 years.
⑧buy /catch → have
e.g.：I have bought the bike for 3 years.（错）改为：I have had the bike for 3 years.
He has caught a cold for 3 days.（错）改为：He has had a cold for 3 days.
⑨borrow → keep
e.g：I have borrowed the book for 3 years. （错）改为：I have kept the book
for 3 years.
还有其它的归纳如下：
leave --- be away borrow --- keep buy --- have die -
-- be dead begin/start --- be on finish --- be over fall ill ---be ill get up---be up catch a cold --- have a cold put on-- wear come/become/go --- be here fall asleep --- be asl
eep get to/ arrive/reach --- be (in) get to know --- know join----be a member of ... (成为…的一
员) open ---be open close ---be close break → be broken \ get up → be up marry → be married \ become → be \ lose → be lost \
8.现在完成时态与一般过去时态的区别
1一般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；现在完成时为过去发生的，强
调过去的事情对现在的影响，强调的是影响。
I saw this film yesterday.（强调动作发生的时间是yesterday 。）
ago, last week/... In 2008, in the past, just now, the day before yesterday, yesterday ... Then(那时),that day, one day, once(从前)

五、单项选择。
1、现在完成时主要强调过去发生的动作对现在造成的影响，或过去发生的动作还未结束，一直持续到现在或将来，重点在于对现在的影响。这种考查难度较大，往往无时间状语，需要从上下文分析、推理才行。故上两侧根据上下文分析、推理，正确答案是B.
2、现在完成时常与already（已经），just（刚刚，正好），ever（曾经），never（从来，也不；从不），before（以前），yet（仍然）等连用。故2应选B.
3、C
4、现在完成时常与recently（近来），so far（到目前为止），in the past/“last + 一段时间”等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间，句中的动作是从过去某一时间或时刻开始持续到现在的。故4应选D.
现在完成时 现在完成时（present perfect tense）通常表示过去发生的动作一直延续到现在，而且还可能继续下去，或者表示过去的行为对现在造成一定的影响，可能还会产生结果等。 1.现在完成时结构 1.1.助动词have/has+动词过去分词。其中，助动词要随着主语的变化而变化，当主语是第三人称单数时，助动词要用“has”。 例：Have you finished your work? He says that he has seen UFOs many times. 1.2.现在完成时的缩写形式：I have=I ’ve have not= haven’t has not= hasn’t 例：I’ve finished my work./He hasn’t finished his work. 1.3.现在完成时的一般疑问句：Have/Has+主语+动词的过去分词+其他？肯定回答：Yes,主语+have/has.否定回答：No,主语+haven’t/hasn’t. 例：----Have you finished your work?----Yes,I have./No,l haven’t. ----Have they arrived?----Yes,they have./No,they haven’t. 1.4.1.通过加-ed的形式来构成规则动词的过去分词，就像我们构成这些动词的过去式方法一样。 大多数动词后+ed.如finish---finished. 以字母e为结尾的动词后+d,如change---changed. 以辅音字母加y结尾的动词，去掉y,再加ied.如carry---carried.
初中现在完成时态讲 解带练习
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
现在完成时趣味讲解 现在完成时的含义 可与现在完成时态相连用的常见时间状语 瞬间动词在现在完成时态中的用法 现在完成时的含义 在当今常见的语法书中对现在完成时的定义大多是：现在完成时是指过去发生的至今已经完成或还在继续的动作。在笔者2011年于《海外英语》中发表的《have + -en的构式研究》中曾指出这一说法的稍欠妥之处。因为过去发生的“已经完成”或“未完成”容易让学生产生疑惑：究竟是不是完成时？ 笔者认为易仲良教授提出的“式态”的说法以及马承老师提出的“现在完成时表示过去已经发生而与现在情况有关系的动作”这一说法更能让学生理解。事实上，我在初中的教学过程当中也是这样跟学生讲解的，学生们能够较好的理解这一说法，并能自然地将现在完成时与一般过去时区分开来。 常与现在完成时相连的时间状语 在初中阶段，多数考查现在完成时的句子当中都有较为明显的时间状语标志词， 比如以下的这些句子（均摘录自人教版教材）：
Have you read Treasure Island yet? I’ve already read it. Have you ever been to a museum? I’ve never been to a science museum. I’ve had this bike for three years. 如果在实际的教学过程当中孤立地让学生记忆这些时间状语标志，无疑会给学生增大学习难度。为了能够提高学生的学习兴趣，我认为可以通过口诀韵律的方式让学生较快地掌握：以前（before）从来不（never）出现，最近（recently）曾经（ever）一两遍（once/twice/many times…）, 自从（since+时间点）刚刚（just）for一段（for+一段），至今（so far/up to now）已经（already/yet）很明显。 在实际的教学过程当中，教师可有意识地讲述两个“已经”(already/yet)及（since/for）的区别着重分章节讲解，让学生在有了整体概念的基础上对各个考点进行突破。 瞬间动词在现在完成时中的用法 在人教版的课本附录的语法讲解中，我们可以看到：“某些动词的现在完成时可表示过去某一时间开始并一直持续到现在（包括”现在“在内）的动作或状态，可以和表示延续的时间状语连用。表示持续动作或状态的动词多是延续性动词”。如：
现在完成时间和现在完成进行时 一、现在完成时 1. 通常使用现在完成时的几种情况 （1）表示过去发生的事对现在的影响 Justin has disappeared, so Kelly is very sad. (Justin 失踪在过去，但是Kelly 至今仍旧为他的失踪感到难过) （2）表示过去的动作一直延续到现在 I haven’t seen Justin since last Friday night. (从上周五晚上到现在一直没有见到过Justin) (3)表示动作的确切时间不明确或不重要 The boy has already come home. (男孩已经回家，但没有指出何时回家) （4）表示刚结束的动作 The police have just finished searching the area. (警方刚结束对该地区的搜查) （5）表示反复发生的动作 Some villagers say that they have seen UFOs many times. (村民曾多次看到UFO) 2. 现在完成时的结构 现在完成时由“have / has + 过去分词”构成。 3. 常与现在完成时连用的时间状语 （1）表示过去的事或动作对现在有影响，动作的时间不明确、不重要或动作刚结束，一般可用already (用于肯定句)、yet （用于否定和疑问句）、ever、just、recently、lately 和never Tom has already come home. He hasn’t finished his homework yet. I’ve met the old man somewhere before. （2）表示从过去开始，并一直持续到现在，一般用for/since短语或由since 引导的时间状语从句。在介词for后一般跟表示一段时间的短语，在since后一般跟表示某个时间的短语，或表示过去时间的状语从句。 We haven’t seen him for two days/since last Monday. We haven’t seen him since he left Nanjing. 4. 现在完成时的应用 (1) 非持续性动词go, come, leave, borrow, buy, die, join的完成时的肯定式不能与时间段连 用，若要接用时间段状语，则应换成相应的持续动词或状态动词。如： He has left. 他走了。 He has been away for an hour. 他走了一个小时了。 Can I borrow that book? 我可以借那本书吗? How long can I keep the book? 这本书我可借多久？ 注意：非持续性动词的否定完成时可与时间段状语连用。如： He has not borrowed the book since then. 从此以后，他再也没有借这本书了。 (2) have / has been to 表示曾经去过某地，但现在不在那儿；have / has gone to表示现在已去 某地，现在不在这儿。如： He has been to Canada, but now he is working in our company. 他去过加拿大，现在在我们公司工作。

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

如何使用现在完成时 同学们我们已经学习了现在进行时、一般现在时、一般过去时、一般将来时这4种时态的用法，但这4种时态还不能满足我们表达的需要。比如：表示“某人过去曾经做过某事”或者“某人做某事多久”，以上五种时态就派不上用场了。这时，我们可以用一种新的时态——现在完成时表示。 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： 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： 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。 3）—Have they found the lost books yet ？他们已经找到了丢失的书吗？ —Yes ，they have．是的，他们找到了。 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。
