现在完成时
一、定义：表示一个动作在过去发生并对现在产生影响
表示一个动作由过去发生持续到现在有可能停下，也有可能延续下去
表示一个动作从过去开始发生到目前为止已经发生多次。
二、构成：现在完成时是由“助动词have / has + 动词的过去分词”构成的，
其规则动词的过去分词构成与过去式相同，不规则动词的过去分词则需加强记忆。
如：I have just cleaned my clothes．我刚洗过衣服。
My brother has done his homework already. 我的弟弟已经做完他的作业了。
友情提示：在现在完成时的各种结构中，have, has均为助动词，无实际意义，只起构成时态的作用，不可省略。当主语是第三人称单数时助动词用has，其余人称一律用have。
过去分词
1 、规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。
四点变化规则：
(1)、一般动词，在词尾直接加“ ed ”。
work---worked---worked ,visit---visited---visited
(2)、以“ e ”结尾的动词，只在词尾加“ d ”。
live---lived---lived ,
(3)、以“辅音字母+ y ”结尾的动词，将 "y" 变为 "i" ，再加“ ed ”。
study---studied---studied ,cry---cried---cried ,
play---played---played ,stay---stayed---stayed
(4)、重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。
stop---stopped---stopped , drop---dropped--dropped
2 、不规则动词：
AAA型
原型过去式过去分词
burst burst burst cast cast cast cost cost cost
cut cut cut hit hit hit hurt hurt hurt
put put put set set set shut shut shut
spread spread spread let let let
AAB型
beat beat beaten
ABA型
become became become run ran run come came come
特殊情况
read read read
read原形发音为/ri:d/,过去式和过去分词发音为/red/
ABB型
bring brought brought buy bought bought build built built
burn burnt burnt catch caught caught dig dug dug
feel felt felt fight fought foughtfind found found
lay laid laid lead led led lose lost lost
make made made meet met met sell sold sold
ABC型
begin began begun blow blew blown break broke broken
choose chose chosen draw drew drawn drive drove driven
drink drank drunk fly flew flown forgive forgave forgiven
三、现在完成时的时间副词
①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。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。
②用ever “曾经”和never“从未”。它们多用于否定或疑问句中。
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。
③用表示到说话为止的过去时间状语，如just, before, up to now, so far, until now, in the past few years等。
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 in the last few days. 近几年他去过那里三次了。
④用for+一段时间，since+时间点。
I've lived here for 15 years. 我已经在这里住十五年了。
I've lived here since 15 years ago. 自从十五年前我就住在这里了。
Mr. Green has worked here since he came to China. 自从来到中国，格林先生一直在这里工作。
三、句型转换：
1. 否定句式：现在完成时的否定句式是“haven't （hasn't）＋过去分词...”。
如：I have not seen the movie yet. 我还没看这部电影。
2. 一般疑问句：Have（Has）+主语+过去分词...
如：—Have you finished the work你已经做完这项工作了吗？
—Yes, I have. 是的，我已经做完了。（No, I haven't. 不，我还没有做完。）
—Has she arrived here她已经到这儿了吗？
—Yes, she has. 是的，她已经到了。（No, she hasn't. 不，她还没有到这儿。）
3. 特殊疑问句：特殊疑问词+have（has）+主语+过去分词...
如：How many times have you been to the Great Wall你去过长城几次？
友情提示：肯定句中有some, already时，改为否定句或疑问句时通常要分别改为any, yet。
如： I have already finished my homework. 我已经完成了我的作业。
→ I haven't finished my homework yet. (否定句)
→ Have you finished your homework yet (一般疑问句)
四、现在完成时的用法：
1. 现在完成时的“完成用法”：表示过去发生或已经完成的某一动作或存在的状态对现在造成的影响或结果。也就是说现在完成时虽与过去有关，但实际上看重的是对现在的影响或结果。例:
(1)He has turned off the light．
他已把灯关了。（动作结束于过去，但说明的是现在的情况——灯现在不亮了。）（2）Who has opened the window
谁把窗子打开了（动作发生在过去，但说明的是现在的情况——现在窗子开着呢。）（3）I've finished my homework now.
现在我已经做完作业了。（说明可以交作业或做别的了）
（4）I have lost my pen. 我把笔丢了。
（5）She has become a teacher. 她已经当了老师。（说明她现在仍是老师）
2. 现在完成时的“未完成用法”：指的是动作开始于过去某一时刻，一直延续到现在，刚刚结束，或可能还要继续下去。此时常与“for + 一段时间”或“since + 表过去的时间点”或“since + 从句”连用。如：
（1）He has lived here since 1978．
自从1978年以来，他一直住在这儿。（动作起始于1978年，一直延续到现在，可能还要继续下去。）
（2）I have lived here for more than 30 years．
我在这儿已经住了三十多年了。（动作开始于30多年前，一直延续至今，有可能还要继续下去。）
（3）He has lived here for 30 years. 他住在这儿三十年了。（现在还住在这儿）（4）They've known each other since childhood. 他们从小彼此相识。（现在还继续往来）（5）How long have you studied English 你学英语多久了（现在仍在学）友情提示：在这类句子的肯定句中谓语动词通常用延续性动词。终止性动词由于动作不
能持续，故不能与for或since引出的时间状语连用。但终止性动词的否定式可与这类时间状语连用。如：
I haven't met him for a long time. 我好长时间没见到他了。
五、非延续性动词到延续性动词的转换,如：
fall asleep (ill) →be asleep (ill)
begin,(start)→ be on open →be open
buy→ have get up→ be up die→ be dead go out→ be out
come→ be in close→be closed
ar rive→be here join→be in, be a +名词
finish( end )→be over leave, move →be away, be out of
borrow →keep catch(a cold)→ have(a cold)
come back→be back put on→wear 或be on
例句：
（1）He has been a soldier for three years.他参军三年了。
（2）His father has been dead for two years.他父亲去世二年了。
（3）The film has been on for ten minutes.电影已开始十分钟了。
（4）We have studied English for three years. 我们（开始）学英语已三年了。
六、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，
I have been to Paris three times. 表明我已经去过巴黎，并且已经回来了，有过这样的经历。
She has gone to Paris. 表明他在去巴黎的路上，现在还没有回来。
一般过去时和现在完成时
（ 1 ）一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是“助动词have/ has + 过去分词”。
(2) 、一般过去时通常与表示过去的时间状语连用。如： yesterday, last week , two
years ago ,just now ,in 2002 等；而现在完成时则常与 just ,already ,ever ,never 等副词和 these days ,this week ,since ......, for ...... 等表示一段时间的状语连用。
试比较以下几组句子，有什么区别：
① A:Have you seen the film
B:Did you see the film
分析：你看过这部电影吗（ A ）句强调的是被问者对剧情是否了解；（ B ）句强调的是看这部电影的动作是否发生过，并不强调是否知道其内容。
② A:How has he done it
B:How did he do it
分析：他是怎么做的这件事（ A ）句强调的是他做着件事的方式对现在产生了某种影响；（ B ）句单纯的询问做这件事的方式。
③ A:He has lived in Beijing for 8 years .
B:He lived in Beijing for 8 years .
分析：他在北京住了 8 年。（ A ）句讲的是到目前为止他在北京住了 8 年，可能还会继续在北京住下去。（ B ）句讲的是他在北京住过 8 年，现在已经不在北京了。
（2）现在完成时强调过去发生的动作对现在的影响和结果，而一般过去时与现在没有联系，只是说明某个动作发生的时间是在过去。
比：I have washed the car. 我洗过了车。（看上去很漂亮）
I washed the car a moment ago. 我刚才洗过车了。
She has watered the flowers. 她已经浇了花。（不需要再浇了）
She watered the flowers yesterday. 她昨天浇的花。
I have written the letter but I haven't posted it yet. 信我已经写好了，但还没有寄出。
I wrote the letter last week and I posted it three days ago. 我上周写的那封信，3天前寄出的。
（3）现在完成时表示的动作或状态延续到现在并可能延续下去，而一般过去时则单纯表示过去某段时间内的经历。
比：It has rained for five hours. 雨已经下了5个小时了。
It rained for five hours yesterday. 昨天下了5个小时的雨。
He has waited for her for two hours. 他等她已经两个小时了。
He waited for her two hours and then went home. 他等她等了两个小时，然后就回家了。
I have reviewed two lessons this morning. 今天上午我已经复习了两课。（说话时还在上午）
I reviewed two lessons this morning. 今天上午我复习了两课。（说话时已是下午或晚上）

高考英语现在完成时真题汇编(含答案)及解析 一、单项选择现在完成时 1．More and more cancer patients _________ in hospital owing to polluted environment and people’s bad lifestyles. A．treated B．have treated C．have been treated D．had been treated 【答案】C 【解析】 【详解】 考查时态语态。句意：由于被污染了的环境和人们糟糕的生活方式，越来越多的癌症病人正在医院里接受治疗。本句主语more and more cancer patients与动词treat构成被动关系，要使用被动语态；而且很多病人接受治疗是已经发生的事情，要用完成时表示，所以本句使用现在完成时的被动语态，故选择C项。 2．The disease is a huge blow for the farmers.

A．change B．changes C．has changed D．have changed

常见的八种英语时态详解 时态（Tense）是表示行为、动作和状态在各种时间条件下的动词形式。因此，当我们说时态结构的时候，指的是相应时态下的动词形式。英语时态分为16种 1. 一般现在时 基本结构：①be动词am/is/are；②行为动词原形或单数第三人称。 否定形式：①am ／is ／are ＋________；②此时态的谓语动词若为行为动词，则在其前加_________，如主语为第三人称单数，则用___________，同时还原行为动词。 一般疑问句：①把be动词放于句首；②用助动词do提问，如主语为第三人称单数，用does，同时，还原行为动词。 提示词：always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 She doesn't often write to her family, only once a month. It seldom rains here .这儿很少下雨。 2）仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。例如：
He can speak five foreign languages . Changjiang River is one of the longest rivers in the world. 3) 陈述客观事实、客观真理。 The earth goes around the sun .地球绕着太阳转。 4) 根据英文语法规定，当主句的谓语动词是一般将来时，那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如： I'll tell him the news when he comes back. 他回来时，我将告诉他这个消息。 If you take the job , they will talk with you in greater details. 5）现在时的特殊用法：一般现在时表过去 1. 用于某些动词(tell, say, hear, learn, gather等)表示不确定的过去时间。如： I hear that he got married last month. 我听说他上个月结婚了。 Mary says you told her to come over here. 玛丽说是你让她到这儿来的。 2. 当要陈述一个客观事实时，有时即使有过去时间状语也可用一般现在时。如： The story is set in the summer of 1937. 故事的背景是1937年夏天。 The story begins in the year 1937. 故事开始于1937年。 练习 1)He always _____ ( get）up early. 2)Mary often ______（do）some shopping on Sundays 3).I’ll go with you as soon as I_______（finish)my homework. 4)If he _______(come) here, I will tell you 5）The earth ________( move) round the sun. 6)Tom sometimes ________(have) lunch at school. 7)Lily usually ________(fly) kites on weekends.

2017年高考英语现在完成时时态总结 一、基本结构：主语+have/has+动词的过去分词 ①肯定句：主语+have/has+动词的过去分词+宾语。 ②否定句：主语+have/has+not+动词的过去分词）+宾语。 ③一般疑问句：Have/Has+主语+动词的过去分词+宾语。 ④特殊疑问句：特殊疑问词或词组+一般疑问句（have/has+主语+过去分词（V-ed）+其他） 过去分词变化规则如下： 1 、规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则： （1）一般动词，在词尾直接加“ ed ”。 work---worked---worked , visit---visited---visited （2）以“ e ”结尾的动词，只在词尾加“ d ”。 live---lived---lived （3）以“辅音字母+ y ”结尾的动词，将 "y" 变为 "i" ，再加“ ed ”。 study---studied---studied , cry---cried---cried （4）重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。 stop---stopped---stopped , drop---dropped--dropped 2 、不规则动词变化需参看不规则动词表逐一熟记。例如： cut- cut- cut, hit--hit-- hit 二、用法
1 、现在完成时用来表示过去发生或已经完成的动作对现在造成影响或后果。也就是说，动作或状态发生在过去但它的影响现在还存在，强调的是现在。 例如：Ihave already posted the photo. 我已经把照片寄走了。强调post对现在的影响“照片不在这里”。 2、现在完成时可以用来表示发生在过去某一时刻的，持续到现在的动作（用行为动词表示）或状态（be动词表示），常与for（+时间段），since（+时间点或过去时的句子）连用。谓语动词必须是延续性动词。 例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。（动作起始于1978年，一直住到现在，可能还要继续住下去。） 注意：for和since的用法。 ①for+时段为…时间 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） 注：瞬间动词（buy,die,join,lose……）不能直接与for 或since 引导的时间段连用。要改变成延续性动词。变化如下：e/arrive/reach/get to-----be in go out----be out finish----be over open----be open

No， he doesn't What does he do for us？ He works for us. （2）一般过去时 be动词＋行为动词的过去式 否定句式：在行为动词前加didn't，同时还原行为动词，或was／were＋not；was或were放于句首；用助动词do的过去式did提问，同时还原行为动词 例如： Did he work for us？ He didn't work for us. He worked for us. （3）一般将来时 am／are／is＋going to＋do 或 will／shall＋do am/is/are/about to + do
am/is/are to + do； 一般将来时的表达方法 be going to +动词原形 be +不定式，be to+动词原形，be about to ＋动词原形 be able to +不定式 be about to+动词原形 will + 动词原形； 例如：He is going to work for us. He will work for us； He is coming.这是特殊的用一般现在时表达将来时态的例子！！ (4)过去将来时 be（was，were）going to+动词原形 be（was，were）about to+动词原形

一、现在完成时的构成 现在完成时态讲解及练习 肯定句：主语+have/ has + done (过去分词)+其它 He has lived in Shenzhen for 4 years. 一般疑问句：Have/ Has +主语+ done (过去分词)+其它 Has he lived in Shenzhen for 4 years? 否定句: 主语+have/ has+ not + done (过去分词)+其它 He has not finished his homework. 过去分词的构成方法如下: 1.一般情况下，直接在动词原形后面加–ed. work---worked answer---answered obey---obeyed want---wanted 2.以不发音的-e 结尾的动词只加–d. Move---moved hope---hoped divide---divided 3.字尾是辅音+y 的动词。则将y 改i 加ed. study---studied tidy---tidied satisfy---satisfied 4.以重读闭音节结尾的词，这些词的末尾只有一个辅音字母时，双写这个辅音字母，再加–ed. stop---stopped regret--- regretted drop---dropped 不规则动词过去式与过去分词分类记忆表 一、AAA. （原形，过去式和过去分词一致） 二、ABB（过去式和过去分词一致） 3)过去式、过去分词-t 替换原形-d 6）过去式、过去分词改为-elt

英语的16种时态 时态（Tense）是表示行为、动作和状态在各种时间条件下的动词形式。因此，当我们说时态结构的时候，指的是相应时态下的动词形式。 1. 一般现在时 英语时态分为16种：一般现在、一般过去、一般将来、过去将来时，以及这四者的进行时、完成时和完成进行时。 用法：A) 表示现在发生的动作、情况、状态和特征。 B) 习惯用语。
C) 经常性、习惯性动作。 例：He always helps others. （他总是帮助别人。） D) 客观事实和普遍真理。尤其要注意，如果前后文不是一般现在时，则无法保持主句、从句时态一致。 E) 表示一个按规定、计划或安排要发生的动作，（仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词）可以与表示未来时间的状语搭配使用。常见的用法是：飞机、火车、轮船、汽车等定期定点运行的交通方式。 例：The next train leaves at 3 o'clock this afternoon. （下一趟火车今天下午3点开车。） How often does this shuttle bus run? （这班车多久一趟？） F) 在时间和条件状语从句里经常用一般现在（有时也用现在完成时）表示将来事情。 例：When you have finished the report, I will have waited for about 3 hours.（等你完成这份报告的时候，我就已经等了将近3个小时了。）2. 现在进行时(be doing) 用法：现在正在进行的动作。 3. 现在完成时(have done) 用法：A) 表示动作到现在为止已经完成或刚刚完成。 例：I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 B) 表示从过去某时刻开始，持续到现在的动作或情况，并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点，或for加一段时间，或by加一个现在时间。 例：Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是：“虽然牛顿是个伟大的人物，但他的许多见解直到今天还在受到挑战，并且被现代科学家的工作所修正。”challenge是及物动词，在本句中应当是被动语态；其动作延续到今天，所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging 都是主动语态，不可能是答案。B) may be challenged虽然是被动语态，但意思与全句内容不合，所以不对。 C) 表示发生在过去，但对现在仍有影响的动作或情况。通常用点动词，如：arrive, begin, find, give, lose等。

A. have been to B. has been to C. has gone to D. have gone to 【答案】 A 【解析】【分析】句意：很多游客多次去过扬州，因为它是如此美丽的一个城市。have been to，表示去过某个地方，have gone to，表示去了某地，还没回来。many times是很多次，游客们应该是去过很多次，用have/has been to+地点，由于主语是复数，助动词用have，故选A。 【点评】考查现在完成时，注意have been to表示去过回来了，have gone to表示去了还没回来。 2．—Where is your father? — .
