T: What animals did you here? Ss: Duck, chick, dog. T: Yes, very good. And where are they? 播放课件：出示图片及本课时题目“At the farm” T and Ss: They are at a farm. 老师拿出单词farm的卡片并用手挡住字母f， 学生很顺利地读出arm, 然后再请学生读 出新单词，由旧知联系新知，学生自己就能掌握farm的发音。 T：Now, listen and guess whats the animal?(点击课件发出声音：Moo) Ss: Its a cow. T: Lets check. (课件出示奶牛图片) Bingo! Its a cow. 教师领读cow, 并抽读学生。 2. T：And now, look, what are they? 课件出示奶牛的阴影，并同时出现句型What are they? 及其汉语意思，让学生对本课时的重点句型的音、形、意有了一个很直观的认识，单词they用醒目的颜色以示强调。此时，老师不断重复“What are they?”让学生认真倾听，好模仿发音。 Ss: Its a cow./ They are cows. T: (课件出示几头奶牛的完整图片) Look! They are cows. 课件出示句子，单词“They”及复数标志“s”用红色以示强调，并重读/Z/。 以小组“开火车”的形式对句型的问答进行操练。 3. :（Show the card “cows”）What are they? Ss: They are cows. T : （Show the card “hens”）What are they? Ss: They are hens. 抽读学生，并纠正复数形式的正确发音。所有的复数名词后面的s都用红色书写，加深印象。老师或遮住S对名词的单复数形式发音进行检测。 老师指向黑板，一起对句型和单词进行比较、认读： What is it? What are they? Its a . They are . 才ow - cows hen - hens 4. T：Listen and guess, whats that? 听音猜动物 Ss: Its a horse. 老师强调字母组or 的发音，把音标写在黑板上。请生两大组开火车PK读单词，看哪一组读得又快又准，然后请生用The horse is .来描述课件上出现的马的特征，描述合理的同学所在组得一动物小卡片贴在黑板上（详见教学评价设计）。 老师指向课件问 How many horses are there? Ss: One horse. 老师拿出horses 卡片，How many horses? Ss: Three horses. 黑板上书写horse 和horses, 并标上音标/iz/, 后重复你单我复的听读训练。 老师指向课件，问“Guess, how many horses are there?”然后一起数“One horse, two horses, three horses.” 5. 课件播放出两张差不多的动物图片，用I can see _ cows/horses/pigs.来描述，然后找出两张图片的不同之处goat.

Ss: They are goats. 将goat的单复数写在黑板上。 出示其他图片进行同样的问答训练 一组问一组答 师出其不意地随意指哪组提问，又随意指哪组回答，考学生的听读能力及注意力。5. 老师露出羊羔图片的一部分让学生看，然后请他们猜“What are they?” Ss: Are they goats? 如果学生提问有困难时，老师可用Are they cows? 给予提示。 T: No, they arent. They are lambs. 同时拿出卡片goats, 用What are they? They are .作对比练习。 请生读单词lambs，老师可随时将s遮住请生读，强调s 发音/z/，然后把单复数写在黑板上。 老师说单数或复数，随意请生说出相对应的复、单数，按每组出错人数的多少分别加分。 7. 出示课件 Pronunciation meet jeep feed sheep 绵羊 课件继续出现 one sheep、two sheep、three sheep，让学生自己发现单复数同形的问题。Step 3 Consolidation 1. 老师指着黑板上的单复数句子及单词大声地对比朗读。 2. 课件播放一些动物的阴影，让学生猜“What are they?
