out.9.The boss has ______________ the office since early this morning.He works hard.七、瞬间动词和持续性动词用于完成时的区别
延续动词表示经验、经历；
瞬间动词表示行为的结果，不能与表示段的时间状语连用。
He has completed the work.他已完成了那项工作。(表结果)
Julia has borrowed the book.Julia已经借了那本书。
I've known him since then.我从那时起就认识他了。(表经历)
Julia has kept the book for 3 days.Julia已借了三天这本书了。
瞬间动词不能和表示一段时间的时间状语连用,但是他可以转换成相应的延续性动词.1.直接用延续性动词
buy– have catch(get)a cold –have a cold borrow—keep Come/go /become—be put on--wear 2.转换成be+名词
join the army – be a soldier Join the Party –be a Party member go to school– be a student 3转换成be+形容词或副词
die—be dead finish – be over begin—be on leave—be away fall sleep – be asleep close – be closed 4.转换成 be+介词短语
go to school– be in school join the army – be in the army 1.我们买这本书三年了.We have had the book for three years.We bought the book three years ago 2.他感冒三天了.He has had a cold for three days.He caught a cold three days ago.1.His uncle ____________(die)for two years.2.He left his hometown three years ago.(改为同义句)He ________ _______ _________ _______ his hometown for three years.瞬间动词和持续动词的练习判断正误：
1.Ann has become a teacher for 4 years.2.Maria has borrowed the CD from me for a over a week.3.Jeff hasn‘t had a day off since last Monday.4.Norman has put the machine right for a few hours.5.The students have finished the homework for a while.6.The front door has been open for 8 hours already.7.The meeting has lasted for two hours and a half.8.Berry has been late for school several times this term.9.I have met Philip once.10.The Greens have eaten the supper for two hours.八、现在完成时和一般过去时的区别
现在完成时表示过去发生的某一动作对现在造成的影响或结果，强调的是现在的情况，所以它不能和过去具体的时间连用,而过去时可以.一般过去时常和过去时间短语连用。1.He ____________(work)in our school for one year.2.He ______(come)to our school last year/in 2002.3.They _______________(cook)the supper already.4.They ___________(cook)the supper half an hour ago.

设计意图：课前一天出示复习指导，让学生充分进行复习，积极主动学习，自主探究的新课标理念，使学生为展示、当堂训练留下足够时间。
二 课前检查
1、小组长进行课前检查预习情况，做好记录，做好平价。
2、教师利用课间抽查预习情况，表扬与激励同步。做到教师心中有数。三 课堂展示（一、)预习检测
1、现在完成时的概念，现在完成时的构成。（4种形式）
肯定句：主语＋ have/has+过去分词＋其他成分。否定句：主语＋have/has+not+过去分词＋其他成分。一般疑问句：Have/Has+主语＋过去分词＋其他成分？ 特殊疑问句：特殊疑问词＋have/has＋其他成分？
2、写出下列动词的过去分词
Stop-----work-----carry------Put----go-----come-----
3、辨析have / has been to 曾经去过某地(已经返回）have / has gone to
到某地去了（还未回，或在途中）的区别，完成下列练习

1、）3年来我的家乡发生了很多变化。
2、）到目前为止，很多的新发明被人们在生活中利用
设计意图 通过这些练习，展示学生预习的成果，理清知识体系，对重难点有了认识，激励学生的学习积极性，培养学生的学习习惯及语言表达能力。(二)探究展示
1、结合47页书中的例句，找出延续性动词与非延续性动词，得出二者的区别。【英语动词根据词义可分为两种，一种是延续性的，一种是终止性的，终止性动词(也可称为非延续性动词、瞬间动词)，如begin, start, die, buy, leave, come等，表示动作的发生与结束于一瞬间完成，不能再延续，所以它的现在完成时不能和表示延续的时间状语连用，即不能与表示一段时间的状语，for+时间段, since+时间点/从句连用，也不能用在how long引导的特殊疑问句中。】
2、如何把非延续性动词运用在for since 引导的句子中？如何变化？
1.open-------be open 2.die--------be dead
3.start/begin-------be on 4.finish--------be over
5.get----beup 6.join-----bein 7.leave-----be away
8、arrive------be here
9、borrow-----keep
10、buy------have
3、用动词的适当形式填空：（注意与一般过去时的区别。现在完成时，强调这一动作产生的结果对现在的影响，与现在有关。一般过去时，仅仅表示在过去某一时刻曾发生过这一动作，与现在无关。）
1.She’s _____________(live)here ever since she was ten.2.Both of them ________________(be)in Hong Kong for ten days.3.Both of them ____________(come)to Hong Kong ten days ago.4.Half an hour __________(pass)since the train __________(leave).5.Mary________(lose)her pen.________ you _______(see)it here and there?
6._________ you _____(find)your watch yet?
四、课堂小结
1、你对现在完成时的认识（时态的概念、构成、运用能力的展示交流）
2、你的收获是什么？（做题的方法，态度上的交流）

2、复习作业 48页（活学巧练）用所给单词的适当形式填空（10----14）3预习作业 预习购物的用语，问路的用语。尝试完成60页补全对话。
第四篇：现在完成时初中教案
现在完成时通常是表示之前已发生或完成的动作，也可以表示持续到现在的动作。以下是现在完成时初中教案，欢迎阅读。
(一)教材分析：
本模块以运动为话题综合运用一般过去时和现在完成时。这两个时态学生容易弄混，但能激起学生强烈的求知欲。而且，大部分同学对这个话题感兴趣，尤其是涉及及自己喜欢的运动项目及运动明星，因此他们乐于谈论。根据这个话题可以设计丰富的教学活动，比如观看各种各样的运动比赛。丰富的课余活动，开运动会等，都能就运动这个话题充分展开讨论，而且能运用任务型教学模式，培养学生的合作精神及创新思维。对运动的讨论还涉及到德育。通过不同的活动使学生认识到，运动能产生美。而运动员身上顽强拼搏，永不服输的精神无疑会对学生产生激励作用。
(二)学情分析：
学生对于姚明非常熟悉，在这班有很多的男同学喜欢打篮球，而且还有一部分女同学喜欢看篮球比赛，他们都是姚明的球迷，我就抓住这个有利的契机，结合学生感兴题的话题把学生吸引住。而且，给合2008年的北京奥运会，来学习本模块中所谈到的有关奥运的知识，这使学生很容易接受。
二.教学设计
(一)教学目标
知识与技能目标：
1、复习实义动词的现在完成时及完成进行时，一般过去时与现在完成时的区别
2、宾语从句的使用，连词的使用过程与方法目标：通过小组活动谈论自己喜欢的运动项目及运动明星。
情感态度和价值观：通过谈论运动及运动员，培养学生养成良好的运动习惯，学习运动健儿永不服输的拼搏精神。
(二)教学重点：
1.实义动词的现在完成时及完成进行时，一般过去时与现在完成时的区别
2.宾语从句的使用，连词的使用
(三)教学难点：
学会用英语描述自己喜欢的运动员能综合运用各种时态，注意连词的使用能与同学就运动这个话题交换信息，开展一些模拟现实生活的活动并表演
11.9 现在完成时
现在完成时用来表示之前已发生或完成的动作或状态，其结果的确和现在有联系。动作或状态发生在过去但它的影响现在还存在;也可表示持续到现在的动作或状态。其构成： have(has)+过去分词。
动词一般是延续性的，如live, teach, learn, work, study, know.举例：
I saw this film yesterday.(强调看的动作发生过了。)
I have seen this film.(强调对现在的影响，电影的内容已经知道了。)
Why did you get up so early?
(强调起床的动作已发生过了。)
Who hasn't handed in his paper?
(强调有卷子，可能为不公平竞争。)
She has returned from Paris.她已从巴黎回来了。
She returned yesterday.她是昨天回来了。
He has been in the League for three years.(在团内的状态可延续)
He has been a League member for three years.(是团员的状态可持续)
He joined the League three years ago.(三年前入团，joined为短暂行为。)
I have finished my homework now.---Will somebody go and get Dr.White?
---He's already been sent for.关于现在完成时上述例举了许多关于它的介绍，同学们可以在例句中寻找现在完成时的真谛。
动词的种类
关于英语中动词的种类知识，希望同学们很好的掌握下面的内容学习。
动词的种类
动词是表示动作或状态的词，按其词义和在句子中的作用可分为行为动词，连系动词，助动词和情态动词。
1.行为动词
行为动词可分为及物动词(vt)和不及物动词(vi)，及物动词表示动作或状态，有完整的词义，能单独作谓语，后跟宾语;不及物动词表示动作或状态，有完整的词义，能单独作谓语，但后面不能直接跟宾语，如要带宾语则与介词或副词构成短语。
如：
More and more people study English.(vt)
The students are listening to the teacher carefully.(vi)
2.连系动词
连系动词本身有一定的词义，但不能独立作谓语，必须与表语一起构成谓语。常用的连系动词有 be, get, turn, become, look, feel, grow, seem, sound, taste, smell等。
如：
Our country is becoming stronger and stronger.It feels damp.3.助动词
助动词本身无词义，不能单独作谓语，只能和主要动词一起构成谓语动词，表示否定，疑问及动词的时态、语态、人称和数等语法特征，助动词有 be,do,have,shall,will等。
如：
How do you usually come to school?
The children are playing yo-yo now.4.情态动词
情态动词本身有一定的意义，但不能独立作谓语，只能和主要动词原形一起构成谓语，表示说话人的语气和情态。情态动词没有人称和数的变化。情态动词有 can(could),may(might),must, need, ought to, dare等。
如：
Can I help you?
-Must we go now?-No, you needn't.a.can与be able to的用法有所区别。can只用于一般现在时和过去时，指本身有能力的“能”;be able to用于各种时态均可，指须经过努力而“能”。
b.must与have/has to的用法。must表示说话人主观认为“必须”，只用于一般现在时和一般将来时;have/has to表示客观需要，意为“不得不”，它可用于各种时态。
c.need和dare既可作情态动词也可作行为动词。
动词不定式的形式
对于英语的学习中，关于动词不定式的形式知识点的内容，我们做下面的讲解学习哦。
动词不定式的形式
1.作主语。如：
To learn English is very important.但实际上不定式作主语常用 it来作形式主语，而将不定式移至谓语动词后作真正的主语。
如上句可表达为：
It's very important to learn English.2.作表语。如：
My idea is to ring him up at once.3.作宾语。如：
I have decided to go to Binjiang Primary School.4.作宾语补足语。
a.ask, want, teach, tell, know, would like, allow等动词后面接动词不定式作宾语补足语。
如： The policemen asked him to get off the bus.b.hear, see, look at, feel, watch, notice, listen to等动词后接不带to的动词不定式作宾语补足语。
如： We often see Miss Li clean the classroom.c.let, make, have这些使役动词后接不带to的动词不定式作宾语补足语。但在被动语态中这些不带to的都须带上to。
如： In those days the bosses often made the workers work day and night.d.动词help接动词不定式作宾语补足语，可带to也可不带to。
如： Can you help me(to)carry the heavy bag?
5.作定语。
a.与被修饰词有动宾关系。如：I have something important to tell you.但如果不定式动词为不及物动词，后面的介词千万不要省略。
如： Maybe they have three rooms to live in.b.与被修饰词有主谓关系。
如： Mr Liang is always the first to come and the last to leave.c.与被修饰之间只有修饰关系。
如： I have no time to play cards.d.作状语，表示目的、原因、方法、方向、结果等。
如： I'll go to meet my friend at the railway station.e.不定式复合结构“for sb.to do sth” 作主语时，常用“It is +adj+ for
of sb.to do sth”的句式。形容词good, bad, polite, unkind, kind, ice, clever,right, wrong, careful等用“It is +adj +of sb.to do sth.”
其他形容词用 for。
如：
It's dangerous for you to ride so fast.It's very kind of you to help me.8.动词不定式与疑问句who, what, which, when, how, where, whether等连用。
如： I don't know when to start.He didn't tell me where to go.但上面结构相当于一个从句，故上述句子也可表达为：
I don't know when we'll start.He didn't tell me where he would go.注意：
a.有些动词或动词短语不能带不定式，只能接动词的-ing形式。
如： enjoy, finish, keep, mind, miss(错过),be busy, go on, keep on, be worth, practise等。
如： The peasants are busy picking apples.Would you mind my opening the door?
b.有些动词后可接不定式，也可接动词的-ing形式，但意思不同。
如： Lu Jian forgot to post the letter.(该寄但还没做)
Lu Jian forgot posting the letter.(已经寄过信了)
They stopped to sing a song.(停止在做的工作而去做另一件工作)
They stopped singing.(停止正在做的工作)
短语动词的四种类型
同学们认真学习，下面是老师对短语动词的四种类型知识总结。
短语动词的四种类型
动词与介词、副词等构成的固定短语，叫短语动词。主要有四类：

注意：宾语是名词时，放在副词前面或后面都可以，但若作宾语的是人称代词时，就只能放在动词和副词之间了。如：
We’ve decided to put the meeting off(=put off the meeting).我们决定把会议推迟。
We’ve decided to put it off.我们决定将它推迟。(不说put off it)
二、动词+介词
如ask for, care for, call for, break into, deal with, call on, look for等。后面必须接宾语。如：

希望上面老师对短语动词的四种类型知识的讲解学习，同学们都能很好的掌握，相信同学们会学习的很好的哦。
及物动词与不及物动词
关于英语中及物动词与不及物动词的知识学习，我们做下面的内容讲解。
及物动词与不及物动词
根据其后是否带宾语，动词可分为及物动词(带宾语)和不及物动词(不带宾语)。如：
When will he arrive? 他什么时候到?(arrive 不带宾语，为不及物动词)
He reached Beijing yesterday.他昨天到达北京。(reach 带了宾语，为及物动词)
有的动词既可用作及物动词也可用作不及物动词：
The child is playing.这小孩在玩。(不及物用法)
The child is playing the piano.这小孩在弹钢琴。(及物用法)
He is writing.他在写字。(不及物用法)
He is writing a letter.他在写信。(及物用法)
The boy is reading.这男孩在阅读。(不及物用法)
The boy is reading a magazine.这男孩在看杂志。(及物用法)
实义动词与非实义动词
下面是对英语中实义动词与非实义动词知识的内容讲解，希望同学们很好的掌握。
实义动词与非实义动词
根据其含义和句子功用，动词可分为实义动词和非实义动词(包括时态助动词和情态助动词等)。如：
He bought a story book.他买了一本故事书。(buy 为实义动词)
He has read the story book.他已读过这本故事书。(has 为时态助动词，read为实意动词)
He should read the story book.他应该读读这本故事书。(should 为情态助动词,red为实义动词)
