T：Is this a/ an ? （设计意图：师生亲切问候完后齐唱欢快的英语歌曲，让学 生很快进入英语学习氛围。自由谈话用学具物品和动物图片 进行交流，先全班同学师问生答，然后随便选一小组同学单 个回答，目的是复习学过的句型”Whats this?” “Is this 个性化修 改 a .” “Yes, it is. / No, Its not. ”及单词，为 新授课做好铺垫 ） StepStep 2 2 PresentationPresentation andand practicepractice 1. New words (1)PPT shows an orange. Ask: Whats this? Do you know? Ss: Sorry, I dont know. T: OK. Let me tell you. Orange, its an orange. Teach and drill orange.(orange, orange, an orange) Read it one by one.

Is this an orange? S3: ) （设计意图：紧接着自由谈话的部分直接导出今天学的水果 单词 orange，自然过度到今天所学的新课，在“Train work”中学生运用实物组内操练句型和单词，很好地练习了 重点句型。 ） (2)PPT shows a red apple and ask: Is this an orange，too? Ss: No, it isnt.(板书黑板) Teach and drill “apple” (apple, apple, an apple) T：I like this apple./ I like apples. Game-Quick response (Using an orange and an apple to hide the back and ask Ss say out correctly. Ask and answer quickly.) Tips: an 用于以元音因素开头的单词前面。 （设计意图：由单词 orange 引出新词 apple，在游戏 Hide and guess 操练时学生非常感兴趣，并在 PPT 上呈现 Tips 让 学生明白 an 的用法。 ） (3)(Take out a pear and ask): Is this an apple, too? Ss: No, it isnt. T: Whats this? Help answer: Its a pear. (follow me to write) Teach and drill “pear”(High and low voice; Little teacher ) PPT show a pear and a ?, Who can ask?

Ask one boy: Is this a lemon? And a girl: Is this a lemon? T: Great, its a lemon. But I dont the lemon. Its sour. （设计意图：lemon 一词的教授我采用了另一种新颖方式， 把一个柠檬装入一个盒子里，以柠檬向同学自我介绍的方 式出场。学生非常喜欢，认真倾听，很容易就学会 lemon 一词。 ） (6)T: I like bananas. Is this a lemon? Ss: No, it ist. Help to answer: Its a banana. Hit the clap to read it. Then chant read: banana, banana , a banana;(Read it group by group) 2. Lets say: CAI shows the fruit and ask Ss say out quickly. (Pictures or words one bye one) 3.

Then listen and number. （设计意图：出示水果色拉叫学生上来品尝，其他同学 以句型“Is this a/an .”来提问品尝者，品尝者用 “Yes, it is./ No, it isnt.”来回答，猜对了的同学上 去品尝继续玩游戏。然后以小组合作形式谈论自己所带的水 果，还可以去问问其他组的同学。学生非常乐于参加这样的 活动，在尝尝、猜猜、说说、乐乐中习得本课水果单词和所 学句型。最后整体出现 B 部分单词听听读读记记，到达熟练 巩固。 ） StepStep 3 3 Learn Part A 1. T: Great, boys and girls. You can talk about the fruit. Mingming and Lingling are talking about the fruit, too. Lets listen and circle the fruit you hear. 2. T: Where are they? Please watch the video. Answer: T: Are they in a classroom? (Show a picture of a classroom) Ss: No. (Teach and rill classroom) T: Are they in a market? (Show a picture of a market) Ss: Yes. T: (PPT) Look. This is a market. It isnt a classroom. (Read and drill them.) 3.T: Look. Whos he? Ss: He is a grandfather. T: Is he happy? Help answer: No, he isnt. He is angry and says: This is a market. It isnt a classroom. (Ask some to read in mood) （设计意图：在学生的自由谈论中教师表扬后组织一句 Mingming and Lingling are talking about the fruit, too.直接导入课文 A 部分的学习，先让学生听他俩谈话圈出 听到的水果单词，再由 PPT 呈现问句，引出 classroom 和 market 的学习。借助图片学生很容理解爷爷说的两句话，并 让学生模仿卖水果爷爷的生气语气来练习句型：This is a market. It isnt a classroom.孩子们积极参与，开心模 仿，乐于表现，练得非常投入。 ） 3. Listen again and repeat of Part A. 4. Group work: Read and act Part A in roles. （设计意图：在图片最后两句难点句子的基础上，再次听录 音跟读，以及组内合作练习 A 部分就非常容易的了。在“分 角色朗读”中可看得出他们的熟练程度。 ） 5、Act and play. 教师用图片或实物在黑板上或讲台上布置 一个模拟市场，教师扮演水果店店主，请两名学生分别扮演 Mingming 和 Lingling，将对话内容表演出来。 StepStep 4 4 ConsolidationConsolidation 1.
