三、教学步骤：

（一）、Warming up

1、Good morning, boys and girls.

p2、 we are going to the zoo.

   Are you ready?  let me check.

p what animals can you see?  (good for you, one star教师自己画. anyone ?yep, you got it, give me five  学生自己画，terrific, wonderful.   总结 you do a good work!)

P what else animals do you know?（come on, tell me. have a try ）

P Listen what’s this? (yeah, horse模仿音)

  P Look, we are here.  hey, pigs？

wow,  How many pigs can you see?(板书)  (6？maybe, what about you? )

Let’s count…(板书)  (finger, finger, 1,2,3…7pigs,there’s one near the gift. wow, the gift is so beautiful.拿出卡片gift,贴在白板上)

 复习单词：cat/rabbit/等 Good —Good work

Look, we are here. How many pigs can you see?(Let’s count…)

 设计意图：设置故事发生的地点、复习动类单词、句型What is this和How many?为后面的搭立支架，从good 到good work,旧知中引入新知识。

(二)、Presentation：

1、Guess and imitate

P Guess, the present is for?（引起兴趣的音）what’s horse like?

（Yeah, a good actor, get a star. a good performance）,Today，I’ll tell you a story about the beautiful gift.

设计意图：由礼物引出故事，学生们猜测礼物是给谁的和模仿中？产生对故事学习的兴趣。

2、listen and answer    tips :结合图文找信息

全文对话录音播放+各题图片依次呈现+讲解

question 1 and question 2

P The present is for ______ （Rabbit板书贴）

P What’s in the gift box?  how many?（12 apples板书 ） (教师one, two, three,  who can help me? let’s count,学生做four, five….12apples, thank you, shake hands.)

设计意图：初看、听故事，借助图片抓取初步信息，学生互动板书，增强参与性、兴趣，为后文推理分苹果和角色扮演作铺垫。

（三）．Practice：

1、Read and learn（默读）

P It’s your turn to read and learn by yourself

If you have any words you don’t know, you can use the note or just ask me, I’ll help you. ok?

 Can you read: Check: good/work . this is for. king. So. right .

and kind（图片解释） What is kind? Look, follow.(学生跟读，读对打钩) kind? no!

so kind means friendly and nice. 老师教读：升降调，kind上，kind下，三大组。每组检测，依据手举高低。

P share(图片解释) what’s the meaning of share?   I don’t know either,

 P so let’s ask Baidu. go ! follow it (到最后一幅，not share , share)

P so share means enjoy together.(教师举高举低，share上，share下，一组)  who can be a little teache?(学生举，测试三大组)

P (you are a good teacher, give me a hug, thank you. )

sh --------she fish ship sheep

设计意图：学生首次默读，发现自己不会的单词，并借助资料理解或询问。教师讲解，解决生单词，为后文的读和理解文章扫清障碍。

2、Read and understand（大声读）

P You can read these words, now, can you read the story loudly and correctly?  tips: try to understand.

设计意图：学生再读课文，再次检测不会读的词,巩固已经学习的新单词和自己理解句子

3、listen an judge （由马的快乐与否引出下节）

 Can you understand? 

P let’s listen and judge.(按题目即故事顺序，依次呈现故事录音，依次回答问题)

判断：P（1）Rabbit wins the race and gets 12 apples.（手势yes or no?）

      P（2）Rabbit eats all the apples（go on , 手势yes or no? ）

 Eats ,no, we can change eats to ?(do you know? can you? look at here! shares贴在黑板上, read it,1,2,go )  (rabbit shares apples with教师举出头像，同学们说，教师贴头像)

     P（3）Horse is always happy.（yes or no）

P it’s a little difficult. Look, in picture 5, Horse is happy, but in picture6 horse is not happy. so the answer is No.

P happy---not happy, what happened?

设计意图：根据故事发展顺序，以借助图片和音频判断正误，并改正的形式，深入学习和理解故事。最后以horse的表情由开心到不开心为切入点，在疑问中，自然地过渡到下一部分学习。

（四）consolidation：

1. follow and infer

P Now, let’s follow the tape and find the reason.

分页播放录音,教师教读：

（1）     起立，加表演，展示abandon boast, rabbit wins the race。good work, rabbit. this is for you. (anyone wanna try? come on! good actor.together!) thank you, lion king.(let’s show, actor? good for you? together!) 

（2）     Wow, apples、how many(全部一起)

(3)注意：教原文，带着动作，再Look，there are three dots,指着教读，感受省略号的用处1,2,34,   5,6,7,8,9,10,11. so three dots, include many words.

we don’t have to read them out. so follow me: Let’s count1,2,3,4,…12apples.(整体呈现，省略号细节分析，再整体呈现)

(4)动作：You have 12 apples. let’s share the apples, pig.

(5)音调和情感：Oh，you are so kind! 教师展示两组：Look，number1 :表情僵硬，语调平静；number2:表情开心，语调激动；（number1 or number2? 2,yeah,Horse is very happy. so follow me, 加动作Oh,you are so kind。）

who can? yeah, so happy, a star.

(6)thank you very much (全部一起)

one for horse, one for me, one for rabbit one for me…

(7)音调和情感：Hey, that’s not right. 教师展示两组：Look，number1 :表情僵硬，语调平静；number2:有动作，语调激动；(1,yeah,Horse is not happy. so follow me, 加动作)

who can? yeah, good pronunciation.

(8)ha! ha! ha!

(9)P we can find Horse’s change from “Happy” to “not happy” is because of pig.

Who can read it again?(come here贴pig头像在学生头上，学生读pig话和在黑板上做出苹果分配)（one for horse, one for me,

one for rabbit, one for me,  one for… ）well down, give me a fist.

P小组讨论：结合上下文和one for句型，推测小猪还没说完的话和还未做完的动作）

one for horse, one for me,  one for horse, one for me,

one for rabbit, one for me,  one for rabbit, one for me,

one for sheep, one for me,  one for sheep, one for me

OK，time’s up, so show us! 学生上台继续说和表演

how many apples will Rabbit have? Let’s count.(黑板的图读)

what about sheep? and horse?  And pig?(6 apples) oh no,

so let’s say like horse ”Hey, that’s not right”

设计意图：教师依据文本，加以动作和情感，让学生不仅会读文段，同时体会出其中的感情，同时在模仿中，为后面的角色扮演搭支架。学生边操作边读，体会句式，为逻辑推测省略号号内容做铺垫。在直观的表达和演示中，体会句式one for… one for…和省略号的作用，培养学生的逻辑思维能力。

2、imagine and act (表演图一到图七)

P (1)what will they do next? Imagine the ending, you may use these sentences. (Group work:Imagine the ending: what will they say an do next？)                                  

(2)Role play（角色扮演）

(3)Tips: 参考用词  vvvyou have three minutes.

P(4) Assessment：Perform the story    Make a new story

P tips   P评价:  三分钟后，ok, time’s up. are you ready?  come on, show us.

boys and girls, a star or two stars, I think they perform well, so two stars, congratulations!

you see, imagination and performance can make the story more interesting.

设计意图：学生在想象结尾中，发散思维和提高综合语用能力，读故事.表演故事.

P  8．Let’s assess

 (2) Hey, don’t be upset, cause, I have this for you and you, let’s share.  (one for…)
