想要更全面地了解“现在完成时课件”我们特别为您推荐这篇文章,要获取更多资讯请到我们的官方网站。老师都需要为每堂课准备教案课件,每位老师都需要认真准备自己的教案课件。只要老师写的教案课件优秀,也能认识到教学过程中不足。

现在完成时课件(篇1)

上一期我们学习了现在完成时的构成,在本期中,我们来学习现在完成时的用法(一)。

现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果。如:

Have you read that story?你读过那个故事吗?(“读”这一动作发生在过去,对现在造成的影响是:是否知道故事的内容。)

I have bought two apples. 我买了两个苹果。 (“买”这一动作发生在过去,对现在造成的结果是:拥有两个苹果。)

在学习这一概念的同时,还应注意常与现在完成时连用的几个副词:already,just,ever,yet,never等。already,just多用于肯定句中,ever,yet,never多用于疑问句和否定句中。如:

I have already finished my homework.我已经做完家庭作业了。

He has just had his meal.他刚吃过饭。

Have you ever sung this English song?你曾唱过这首英文歌吗?

They haven't started yet.他们还没有动身。

We have never heard of it.我们从来没有听说过这件事。

现在完成时表示过去的动作对现在造成的影响;一般过去时表示动作发生的时间在过去。试比较:

The plane has arrived . 飞机已经来了。(说明现在的情况:飞机在这儿。)

The plane arrived a quarter of an hour ago. 飞机是一刻钟以前抵达的。(强调动作发生的时间在过去。)

接触六:have been in, have been to 与have gone to 的用法

1. have(has) been in 意为“已经在某地呆了多长时间”,常与表示一段时间的状语连用。如:

Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经有三天了。

They have been in Canada for five years. 他们到加拿大有五年了。

2. have(has) been to意为“曾经去过某地”,表示现在已经不在那里了。可与just, ever, never等连用。如:

I've just been to the post office. 我刚才去邮局了。

Have you ever been to Hangzhou? 你曾经去过杭州吗?

Mary has never been to the Great Wall. 玛丽从未去过长城。

3. have(has) been to 后面可接次数,表示去过某地几次。如:

I've been to Beijing three times. 我去过北京三次。

They have been to that village several times. 他们去过那个村庄好几次了。

4. have(has) gone to 意为“到某地去了”,表示到了某地或正在去某地的途中。总之,说话时该人不在现场,一般不用第一、第二人称代词作句子的主语。如:

-Where is Tom? 汤姆在哪里?

-He has gone to the bookshop.他到书店去了。

下列各句均有一处错误,请指出并改正。

1. So far we learned about six hundred English words.

2. I've been in Australia twice.

3. -Have you had your lunch?

-No yet.

Key:

1. learned → have learned 2. in →to 3. No→Not

2)表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等,在完成时当中不能和表示一段时间的状语连用,因为它们表示的动作不可能持续。因此,不能说: He has come here for 2 weeks. × The old man has died for 4 months. × They have left only for 5 minutes. × 以上三句话可以改为:

He has been here for 2 weeks.

The old man has ______ _______ for 4 months. They have _____ _____ only for 5 minutes 2)have (has) been 和have (has) gone的区别:表示“曾到过某地”要用 “have (has) been”; 表示“已经去某地”要用 “have (has) gone”。试比较:

现在完成时课件(篇4)

现在完成时表示过去发生的动作对现在造成的影响或结果或表示过去的动作或状态持续到现在。为了方便老师们教学,分享了现在完成时的课件,一起来看看吧!

(一)教材分析:

本课为初三年级语法复习课,在已经复习完动词一般现在时,一般过去时,一般将来时,现在进行时和过去进行时的基础上,进行动词时态中最重要的现在完成时的复习。课时分配为两节讲练结合课和两节专项练习课。本课为讲练结合课的第一课时。

(二)学情分析:

学生在初二年级学习过现在完成时后,一直没有进行过系统的复习。在前阶段的语法复习中能够看出来学生的对于该语法项目遗忘程度比较严重。而现在完成时在中考中的地位较高,是单选的每年必考的项目,所以针对学生的现状和考试的要求,都要在该时态复习时下一番功夫。

复习现在完成时的构成和两种基本用法。

现在完成时与一般过去时的区别。

have been to, have gone to和have been in的用法。

(三)教学难点:

1.现在完成时与一般过去时的区别。

2.have been to, have gone to和have been in的用法。

三.课堂流程:

1.复习现在完成时的构成和两种基本用法。

2.现在完成时与一般过去时的区别。

3.have been to, have gone to和have been in的用法。

教学重点 复习现在完成时的构成和两种基本用法。

1.现在完成时与一般过去时的区别。

2.have been to, have gone to和have been in的用法。

Translate the following sentences

1. I have lived in Beijing.

2. He has already seen the film.

3. I have not had his lunch yet.

4. She has not visited your school before.

5. Have you ever been to the Forbidden City before ?

6. I have never been to that farm before.

7. I have just lost my English book.

主语+have / has  +  过去分词+~

1)现在完成时态表示 过去发生的动作对现在造成的影响或结果 。

标志词:already   ,yet , just,  before,  never ever

1. A: ______ your brother _________ a new watch?  (buy)

1.提出问题,让学生进行小组讨论:

⑴ When is the Present Perfect Tense used?

⑵ What’s the difference between “have/has gone to” and “have/has been to”?

⑶ What kinds of words or phrases can be often used in the Present Perfect Tense ?

2.检查讨论情况并做典型题例。

此步骤目的在于引导学生进行小组合作,培养合作精神。

Step 4 Revise the difference between the two types of the tense(区别一般过去时与现在完成时)

1.先让学生做一些相关练习,让学生自己发现两种时态的区别并及时总结。

2.让学生举例说明。

此步骤的目的在于鼓励学生主动探究,调动他们学习的积极性和主动性。

2.让学生自己归纳总结瞬间动词转化为延续动词的用法。

初中阶段常见的终止性动词转化成延续性动词有:

come to → be in(at) come back → be back

begin/start → be on join→ be in/be a member of

leave → be away get to know → know

finish → be over fall asleep → be asleep

catch a cold → have a cold fall ill → be ill

come to work here → work here leave here → be away from here

规律: 除了borrow → keep buy → have 其余都可以转化为be +介词或副词或形容词。

口诀:

终止性动词一瞬间,不与时段紧相连。

来买发现停止参加开始变得死离开……

用时千万别胡来,记住要用别的动词来替代。

注:where 和when 引导的.从句一般不用现在完成时,但Where have you been ?除外。

此步骤目的在于鼓励学生积极参与,扩大学生的参与面。

利用学生的竞争心理,让学生以小组为单位进行组间竞赛,得分多者为胜,以此调动学生学习的积极性和兴趣,同时达到巩固现在完成时的目的。

练习I. 用already, yet, ever, never, just填空

设置两个情景,让学生自选两人一组编一个对话,并且用上现在完成时态,将语法知识拓展运用到实际生活当中,引导学生主动探究实践,促进学生多方面能力的综合发展。

熟练掌握现在完成时的用法。

板书设计:

肯定句式:现在完成时的肯定句式是“have(has)+过去分词”。

否定句式:现在完成时的否定句式是“haven't(hasn't)+过去分词”。

疑问句式: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。

肯定回答用“Yes...have(has).”。

否定回答用“No...haven't(hasn't).”。

现在完成时课件(篇5)

用来表示之前已经发生或完成的动作或状态,而其结果却和现在有联系,即:动作或状态发生在过去,但它的影响现在还存在。

--他们已经离开了,也就是说现在他们人不在这里。

ihavehadmylunch.

--我已经吃过午饭了,也就是说我现在不饿。

也可表示持续到现在的动作或状态。

eg:hehaslearnedenglishsince.

--从开始学的,现在还在继续学。

(通过举例子来理解现在完成时的含义,由浅入深,层层递进,学以致用)

现在完成时与一般过去时的区别:

现在完成时表示的是在过去某个时间开始并持续到现在的动作/状态,或者发生在过去却对现在造成的影响

(用数轴的形式来理解区别,更直观形象,更易接受,符合初中生学习的心理特点)

a.liu'aoisnothungry.hehasalreadyeaten.

b.su'anishungry.he'snoteatenyet.

c.haveyoueatenyet?

由此already一般用于肯定句中,yet一般用于否定句和疑问句中。

我们已完成作业了。

wehavealreadyfinishedourhomework.

他们还没有完成作业。

theyhaven’tfinishedtheirhomeworkyet.

a.i’vebeenheresince.

b.she’sbeenthereforanhour.

since:引导的短语表示时间点,意为“自从…以来”,如since1982

请在下列时间前填上for或since:

(这种归纳总结在语法教学中屡试不爽,反应也还比较快,效果可见一斑)

三、汉译英。

4、她还没有看过那部新电影。

5、她去过上海。

6、他这些天上哪儿去了?

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)

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

6、现在完成时时常与“for +时间段或since +过去时间点”连用(含

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。

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”
