How old are you?2Review:复数名词和数字。延续上节课的猜测游戏：桌子上放着一个铅笔盒，里面有一支铅笔。T: Whats this?S: Its a pencil-case.(教师将铅笔盒藏起来再问学生)T:I cant find my pencil-case.

5、the two books. How many books do I have?(如果学生不能正确理解puton，教师可以边说边做动作)Ss: Seven books.T: Let me put twelve books on the seven books. How many books do I have?Ss: Nineteen books.请单个同学解释puton的含义。如果学生还是不能理解的话，教师可以适当多做几次示范。 三、拓展情境 达标训练练习句型How many ,总结句型特点。T：（找一名刚才在游戏中没有被提问过的学生，拿起他的卡片）Whats this?Ss：A chair

6、.T:(翻过来，看chair数字) How many chairs in our classroom?Ss: Twenty-two chairs.T:(问全班) Can you ask?(换另一个同学的卡片)S1：Whats this?S2:A boy.T:How many boys?Ss: Twenty boys.T:Ask and answer in your group.How many 句型用来提问数量，How many后面的名词要加s(也就是用名词复数)。四、聚焦情境 反思构建1T:How many books does Danny have: Listen to the tape

7、and answer the questions.T:First,How many books does Danny have?(只放一、二幅图的录音)S;Eight books.放第三、四幅图的录音（提示学生are,there也表示“有”）T:How many books are there on the desk?S:sixteen books.齐读最后一部分：T:What happened?S:Danny falls down.师生一起总结表示“有”的词has、 have、there be并进行简单的区分。 第二课时一、带入情境 确立目标1问候：T：Hello!
