一、初中现在完成时教学现状

现在完成时是初中英语语法教学中的重点与难点, 这个时态横跨了两个时间段——过去和现在。这个时态中所表示的动作发生在过去, 但是其强调的是动作对现在有影响或者结果, 同时这种影响或者结果是说话人所关注的点, 因此经常出现后面不用时间状语的情况。

但现在完成时和一般过去时进行混合的时候, 学生往往都很难完全地进行把握和理解, 容易产生一些错误。在英语语法中, 能够与现在完成时态有较大关系, 并且会产生困惑的主要就是一般过去时态。只有在通过对比后, 才能够发现它们的差异。但是能够让人产生困惑的地方仍然会有, 这是因为学生没有理解透彻现在完成时。

二、初中英语现在完成时教学策略

1.明确时态的实际意义

对于现在完成时, 必须让学生明白其表达的是“用过去的动作来对现在的情况进行说明”。从动作来看, 是过去发生的动作, 但是既不说明动作发生的时间, 也不对动作的情境进行强调。从实际意义上来看, 现在完成时描写或说明的是现在的情况, 或说明动作所造成的影响, 是对动作发生后对现在所产生的结果进行强调。例如“I have already posted the photos.”意思是我已经把照片邮寄了, 强调的是过去某个时刻邮寄照片的这个动作对现在所照成的影响与结果——“把照片寄出去了, 不在我这里了”。

2.利用实际情境帮助学生理解现在完成时

在对现在完成时进行教学时, 需要通过实际的情境来帮助学生进行理解。例如, 在一开始上课的时候, 教师从讲台走向教室门, 在走的过程中说:“I’m going to open the door.”当走到教室门边并开门时, 边开门边说:“Now, I’m opening the door.”当门被打开之后继续说:“I have opened the door.”接着将这三个句子板书出来, 并标出谓语动词have opened, 然后告诉学生句子中标出来的谓语动词就是今天要学习的现在完成时。这种时态表示的就是在说这句话之前, 开门的这个动作就已经完成了, 并对现在造成了门是开着的结果。然后又让学生来进行表演, 让学生将开着的教室门关起来, 在其关上教室门的时候, 教师可以对学生说:“He has closed the door.”接着在黑板上将句子板书出来, 并在has closed下面进行标记, 告诉学生“has closed”这个动作完成了, 强调的是现在门是关着的。通过这样的方式让学生对于现在完成时产生一个较为直观的印象, 在这样的基础上来开展教学, 将能够让学生更加容易理解这个时态。在这个基础上启发学生对现在完成时的结构进行总结:“主语+助动词 (have、has) +动词的过去分词”。

3.注重练习

对于某些知识来讲, 仍然是需要注重一定量的练习, 为此不能够对机械练习进行过分的排斥。因此, 在教学现在完成时的过程中可以进行一定的模仿与重复练习, 让学生进行简单的操练。操练主要可以采取以下两种方式:

(1) 开放式的操练。这部分的练习主要的对象是成绩较为优秀的, 因为他们的学习能力与接受能力相对较好, 所以可以鼓励他们去造出一些具有新意的句子, 例如:

My dog has lived with me for 3 years.

I have studied here for 5 years.

My father has worked in that car factory for 20 years.

……

(2) 半开放式的操练。教师可以在黑板上写出一些时间短语与一些动词 (过去分词形式的) , 这样可以对那些基础不是很好、接受能力与理解能力较弱的学生进行照顾, 让他们能够有所提高。在他们对基本的句子结构进行掌握之后可以进行难度提升。

综上所述, 现在完成时有着非常重要的地位, 同时学生在学习的过程中也很容易将其与一般过去时混淆, 这不仅不利于学生在中考中获取高分, 同时也会对学生运用英语进行会话产生影响。因此, 我们需要对现在完成时的教学进行重视, 让学生在一定的情境之下去对其含义进行领会, 在这样的基础上结合必要的训练可以产生较好的效果。

3.现在完成时入门 篇三

一、用法

1.意义：(1)现在完成时表示过去发生或已完成的某一动作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，但实际上着重的是对现在的影响或结果。例如：

I have bought two new books.

我买了两本新书。（“买”这一动作发生在过去，对现在造成的结果是：拥有两本新书）

(2)现在完成时还可以表示过去发生的动作一直持续到现在， 有可能还会持续下去。例如：

I’ve been here since February.

我从二月份起就在这儿了。（“在”这个动作发生在过去，但一直持续到现在）

2.标志词：与现在完成时连用的常用副词有：already，yet，just， never， ever， before等。例如：

I have already sung this song.

我已唱过这首歌了。

He hasn’t known this news yet.

他还不知道这个消息。

小提示：already，just多用于肯定句中，yet， ever， never多用于疑问句和否定句中。例如：

He has just had his meal.

他刚吃过饭。

Have you ever read this story?

你曾读过这个故事吗？

二、构成

1.肯定式：由“have / has +过去分词”构成。例如：

We have seen that film.

我们已经看过那部影片了。

She has gone home.

她已经回家去了。

小提示：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。译成汉语时，往往用“已经”“过”或“了”等。

2.否定式：由“have / has +not +过去分词”构成。have，has与not可以分别缩写为haven’t， hasn’t。 例如：

He hasn’t come back yet.

他还没有回来。

小提示：现在完成时的否定句末往往加yet，时常译为“还没有……”。

3.一般疑问句：将have/ has提到主语前，简略答语为：“Yes， 主语+ have/ has（肯定回答）” 或“No， 主语+ haven’t / hasn’t（否定回答）”。例如：

—Have you ever made cakes?

—Yes， I have. / No， I haven’t.

——你做过蛋糕吗？

——是的，我做过。/不，我没做过。

—Has she eaten that orange?

—Yes， she has. / No， she hasn’t.

——她吃了那个橘子了吗？

——是的，她吃了。/不，她没吃。

小提示：现在完成时的一般疑问句往往在句末加yet。汉语译为“……过吗？”或“还有……吗？”等。例如：

—Has Jim finished his homework yet?

—No， not yet.

——吉姆完成家庭作业了吗？

——不，还没有。

语法•剖析

ⅰ.现在完成进行时

1.现在完成进行时表示从过去到现在的一段时间内某个动作一直在持续，到现在为止，该动作可能已不再持续，也可能还在进行。这要根据上下文来确定。句中常含有表示一段时间的状语。

she is very tired.she’s been typing letters all day.她很累了。她整天都在打信件。(现在可能仍在打字，也可能刚刚停下。)

i’ve been working for the company for 15 years.我已经在这家公司干了15了。(可能仍在这家公司，也可能刚换工作或退休。)

从以上两个句子中可以看出，第一个句子里，工作尚未完成;第二个句子里，这项工作已经完成了。

2.某些动词，如learn,lie,live,rain,sit,sleep,stand,study,wait,work等本身就有持续性，故常用于带有since或for的完成进行时;以及how long开头的疑问句中。

我已经睡了至少8个小时了，可还是觉得累。

how long have you been waiting here?你在这儿等多久了?

7.“现在完成时”入门秘籍 篇七

一、现在完成时由“助动词have(has)+动词的过去分词”构成:

(1)肯定式:主语+助动词have/has+动词的过去分词+其它。如:

She has finished her homework. 她已做完作业了。

We have cleaned our classroom. 我们已打扫完教室了。

(2)否定式:主语+助动词have/has+not+动词的过去分词+其它。

现在完成时的否定句直接在助动词have/has后面加上not, have not与has not可分别缩写成haven’t与hasn’t。肯定句中有already时,否定句中一般要改为yet。如:

Miss Gao hasn’t come back yet. 高老师还没有回来。

They haven’t spoken to a foreigner. 他们还没有与外国人说过话。

(3)一般疑问式:助动词Have/Has+主语+动词的过去分词+其它?

现在完成时的一般疑问句直接把have/has提到主语之前,同时也要把句中的already改为yet。肯定的简略回答为:“Yes, 主语+have/has.”,有时也可用“Yes, already.”。否定的简略回答为:“No, 主语+haven’t/hasn’t.”,有时也可用“No, not yet./No, never./Not yet.”等。如:

“Have you returned the book?” “Yes, I have.” “你把那本书还了吗?” “是的,我还了。”

“Have you found your lost bike yet?” “No, not yet.” “你找到你丢失的自行车了吗?” “还没有。”

【温馨提示】在现在完成时的各种结构中, have/has均为助动词,无实际意义。当主语是第三人称单数时要用has。have/has后接动词的过去分词。

二、现在完成时的用法:

1.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和结果,常与时间副词already, yet, just, ever, before等连用。如:

I’ve finished my homework already. 我已经完成作业了。

She hasn’t found her dog yet. 她还没有找到她的狗。

They’ve just arrived here. 他们刚到这里。

We have never been to Beijing. 我们从来没有去过北京。

Have you been here before? 以前你来过这儿吗?

2.现在完成时还表示过去发生的动作延续至今还可能继续下去。常和for, since引导的一段时间的状语连用。如:

I’ve lived here for 20 years. 我在这儿住了20年了。(还可能住下去)

She has taught us since I came to this school.

自从我来到这学校,她一直在教我们。(可能再教下去)

三、现在完成时延续性动词与终止性动词的转换:

延续性动词:表示动作可以持续一段时间的动词。如:be, live, study, speak, talk, wait, walk, sleep, learn, have, keep, know等,它们可以和表示一段时间的词连用。

终止性动词:表示动作在瞬间就完成的动词。如:come, go, leave, begin, start, lose, buy, join, die, get to, arrive, reach, finish等,它们不能用在how long引导的疑问句中,也不能和表示一段时间的词连用。但是在否定句中,它们可以和表示一段时间的词连用。如:

I haven’t gone to Beijing for two years. 我已有两年没有去北京了。

在现在完成时中,当与表示一段时间的词连用时,终止性动词可以和延续性动词进行转换。如:come to→be in(at), come back→be back, begin/start→be on, borrow→keep, buy→have, join→be in/be a member of, die→be dead, become→be, leave→be away, get to know→know, finish→be over, fall asleep→be asleep, catch a cold→have a cold。

现在完成进行时与现在完成时的区别

10.点击现在完成时被动语态 篇十

一､掌握现在完成时被动语态的构成

现在完成时被动语态的结构为has/have been done，使用has been done时，主语为单数;使用have been done时，主语为复数。

例1:This book has been translated into many languages.

这本书已被译成多国文字。

例2:My homework has been done. 我的家庭作业已经完成了。

二､理解现在完成时被动语态的概念

现在完成时被动语态是强调一个发生在过去的被动性动作对现在造成的影响。

例1:Our classroom has been cleaned. You needn’t clean it now.

我们的教室已被打扫，你没必要再打扫了。

析:该句强调教室已被打扫，对现在造成的影响是教室是干净的，强调这个影响，你就没必要再打扫了。

例2:These flowers have been watered; you can go home.

这些花已被浇水，你可以回家了。

析:这些花已被浇水，对现在造成的影响是你没必要再浇水了，强调这个影响，你可以回家了。

现在完成时被动语态还可强调到目前为止已存在若干时间的被动性动作或状态。

例1:This book has been published for two weeks.

这本书已被出版二周。

例2:This work has been done for two hours.

这项工作已被做完两小时了。

三､掌握现在完成时被动语态的用法

1.在不知道动作执行者是谁时

His bike has been stolen. 他的自行车被人偷了。

(是被谁偷的，不清楚。)

2.当动作执行者是泛指或不言自明时

Not a book in the library has been taken away.

图书馆里的书没有一本被人拿走。(没人拿书，泛指)

3.虽然可以说出动作执行者但动作承受者是谈话中心或特别需要强调

My watch has been repaired. 我的表修好了。

(表修好了是谈话的主旨，是谁修好的无关紧要，不必提及。)

4.出于委婉､礼貌而避免提及自己或对方时

Enough has been said here on this question.

关于这个问题，已经谈得不少了。(意思是说:大家不要再说了。)

5.在文章标题､广告､新闻等中(常用省略助动词be的被动语态)

Road Blocked. 道路已被堵塞。(新闻报道，省略了助动词has been。)

6.当动作的执行者不是人时

The house has been washed away by the storm.

房子已被暴风雨冲走了。

7.在商务书信中书信起草人是以公司名义时

Your letter has been received. 来信收到。

(这是公文往来的用语，朋友之间若这么写就显得太冷漠了。)

四､掌握现在完成时被动语态的各种句型变换

从现在完成时被动语态结构has/have been done可以看出has/have为助动词，因此现在完成时被动语态的各种句型变换均应借助于has/have来完成。构成否定句时直接在has/have后面加not，构成一般疑问句时将has/have提前。

例1:Has this bridge been finished?这座桥竣工了吗?(一般疑问句)

例2:His homework hasn’t been finished.

他的家庭作业还没有被完成。(否定句)

例3:The blackboard has been cleaned， hasn’t it?

黑板已被擦了，是吗?(反意疑问句)

例4:Where has this film been put on many times?

这场电影在哪儿被上演过多场?(特殊疑问句)
