现在完成时讲解及练习
Unit 9:现在完成时讲解
一．基本结构：助动词have/has+过去分词(done)
二．句型：
否定句：主语+have/has+not+过去分词+其他.
一般疑问句：Have/Has+主语+过去分词+其他.
简略答语: Y es, 主语+ have/has.(肯定)
No, 主语+ haven't/hasn't.(否定)
三．用法
（1）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
I have spent all of my money (so far).(含义是:现在我没有钱花了.)
Guo zijun has (just/already) come. (含义：郭子君现在在这儿)
My father has gone to work.(含义是:我爸爸现在不在这儿)（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.
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.
四．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)
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. /sin ce two months ago.
五．现在完成时的标志
1. 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
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
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
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（到目前为止）为标+before
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考试。
2.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。
* ①for+时段②since+过去一个时间点（过去从句）为标志
注意：1)现在完成时不能单独与过去的时间状语连用, 如yesterd ay,last week, three years ago 等; 2)不能与when连用 2.现在完成时往往同表示不确定的过去时间状语连用
六．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 ”。

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

参考答案：
一、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。
5、C
6、现在完成时时常与“for +时间段或since +过去时间点”连用（含从句，从句过去时）。故6应选C。
7、C
8、现在完成时还与once（一次），twice（两次），three times（三次），several times（几次）等表示重复次数的词语连用。故8应选B。
9、现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , last week , a moment ago 等）连用。故9的正确答案为B。
10、B
11、现在完成时中，非延续性动词不能与for和since引导的表示一段时间的状语连用，通常是用相应的延续性动词来代替。故11的正确答案依次为：D。
12、B 13、A 14、C 15、A。
16、“have/has gone to + 地点”表示“某人去了某地（还未回来）”，指主语所指的人不在这儿。“have/has been in + 地点”表示“在某地呆了多长时间”，常与表示时间的状语连用。“have/has been to +地点”表示“曾经去过某地（但现在已不在那儿）。”故16的正确答案为A。
17、A 18、D 19、C 20、C
二、句型转换。
1、has he?
2、How long
3、died, has been dead
4、has been open
5、has been away
6、joined；ago
7、It is, since 8、The bus has been here for ten minutes.
三、汉译英。
1、Jim has finished doing his homework already. He is free now.
2、He received a letter yesterday.
3、My father has been to the Great Wall before.
4、She hasn't seen the new film yet.
5、She has been to Shanghai.
6、Where has he been these days？
人教版八年级下册现在完成时专项讲解
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.
现在完成时趣味讲解
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：
八年级英语下册-现在完成时态的讲解与练习-人教新目标版
现在完成时讲解与练习 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.用法 （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 have't seen her for four years. 我有四年没见到她了。 3．结构 1）．陈述句结构：主语＋have( has)（not）+过去分词＋其它。have not=h aven’t has not=hasn’t. 2）．一般疑问句结构：Have( Has )＋主语＋过去分词＋其它 3）．特殊疑问句：特殊疑问词＋have(has) +主语+ 过去分词＋其它 eg. He has already finished his homework. He hasn’t finished his homework yet. Has he finished his homework yet --Yes, he has./ No, he hasn’t./ No, not yet. （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。 4.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。 He has been there three times the last few years.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. 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“be（在）”等延续性动词来表述。现归纳总结一下由非延续性动 词到延续性动词的转换： arrive→be here begin(start)→be on die →be dead come back→be back leave →be away fall ill(sick,asleep)→be ill(sick,asleep) get up→be up go out → be out finish →be over put on →wear 或be on open →be open join →be in或 be a member of… close →be closed go to school→be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study→study come to work →work等 如：He has been a soldier for three years.他参军三年了。

中考中考英语总复习现在完成时专项及解析 一、初中英语现在完成时 1．Little Tom his home for more than ten years. A. leaves B. left from C. will leave D. has been away from 【答案】 D 【解析】【分析】句意：小汤姆离开家已经十年了。由句中“for more than ten years”可知. 句中的谓语动词需使用延续性动词。leave对应的延续性动词为be away。 【点评】考查现在完成时。 2．—Do you still play basketball? —Oh, no. I ____ it for the past two years. A. haven't played B. didn't play C. won't play D. hadn't played 【答案】A 【解析】【分析】句意：——你还打篮球吗？——哦，不了。我已经有两年没有打过了。根据句中的for the last two years可知应与完成时态连用，又有时间是the last two years可知是从现在往前两年，因此应使用现在完成时态，故选A。 【点评】考查动词时态中的for+段时间与完成时态连用，根据时间确定是现在完成还是过去完成。 3．I scared of dogs ever since a dog hurt me when I was five years old. A. will be B. was C. have been D. would be 【答案】 C 【解析】【分析】由since引导的从句可知主句应用现在完成时，故答案为C。句意是：自从我五岁时被狗伤过之后我就一直怕狗。 【点评】本题考查现在完成时的用法。 4．—Where is your father? — . A. He has been to Shanghai B. He has been in Shanghai C. He has gone to Shanghai D. He have been to Shanghai 【答案】C 【解析】【分析】句意：－你的父亲在哪儿？－他去上海了。Have been to去过某地（已回）；have been in在……；have gone to去了某地（未回）。本题中父亲是人们在找的人，所以是去了某地，还没回来，用have gone to。主语he是三人称单数，用has gone to。故选C。

现在完成时的用法讲解#精选.
现在完成时的讲解 对所学时态的回顾，引入现在完成时 通过数轴来概括讲解所学的四个时态：一般现在时、现在进行时、一般过去时、一般将来时。（导入）有时候，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。同样也用数轴来表示一下。 一现在完成时的构成:主语+ have/has + 过去分词 (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。 eg .I have taught English in this school since 1999. 二、否定式:主语+ haven’t/hasn’t + 过去分词。 疑问式: Have /Has + 主语+ 过去分词? 简略答语: Yes, 主语+ have/has.(肯定) No, 主语+ haven’t/hasn’t.(否定) —Have you finished your work? —Yes,I have. 三现在完成时的含义之一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， 常与already/yet，just，never/ever，before, so far等连用。这些标志词可以表达这种含义. 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？
