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.

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。

现在完成时知识讲解讲课教案

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

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？
