现在完成时讲解学案

李斌2013-09-02

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: Yes, 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,持续到现在的动作甚至有可能继续延续下去。

I have worked here for 12 years.

She has been a teacher for 20 years.

I have lived here since 2002.

注：在这类句子的肯定句和疑问句中谓语动词必须用延续性动词。短暂性动词即非延续性动词由于动作不能持续，故不能与for引出的时间状语连用,也不能和since时间状语连用。如：

1）他入团两年了。

误：He has joined the League for two years．

正：He has been a League member for two years．

2）我买这辆自行车三年了。

误：I have bought this bike for three years．

正：I have had this bike for three years．

3）误：His father has joined the Party since 1978.

正：His father has been in the Party since 1978.

▲部分短暂性动词：enter; come; leave; see; finish; die; join; borrow; buy; catch; get;

begin; start; become；arrive; reach; hear; close; lose; fall; put on; receive

注意：非延续性动词的否定形式可以与表示延续一段时间的状语连用。即动作不发生的状态是可以持续的。

（错）I have received his letter for a month.

（对）I haven't received his letter for a month.

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. /since two months ago. 五．现在完成时的时间状语标志

1. 句中出现just(刚刚)，already，yet(直到现在;尚;还;仍然), never，ever，等词时句

子一般使用现在完成时。already一般用于肯定句中，yet一般用于否定句和疑问句中。ever和never表示“曾经”和“从未”等。

例如：I have just finished my work. 我刚刚完成工作。

I have already had my lunch.

He hasn't found the answer to the question yet.

再如： -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。

2. so for; to date; up to now; up till now；by now “迄今”

3. in the past/last + 一段时间。如：

Great changes have taken place in the past 30 years.

4. since + 过去的时间点。如：

We haven’t seen each other since 1998.

5. since +从句（从句用一般过去式），主句（主句用现在进行时）

Mr. Mike haven’t gone abroad since he went to Japan in 2003.

6. before 作副词，意为“从前；以前”，位于句末。如：

I have seen such a person before.

7. 句型：It is the first/second time that 从句（从句用现在完成时）

It is the first time that I have seen the famous writer in person.

这是我第一次见到这个著名作家本人。

8. 句型: It is/has been +一段时间since从句（从句用一般过去时）如：

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.

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.

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
