Unit 4 Where’s my schoolbag (Grammar Focus—3c)教学设计
教材分析:本部分首先通过表格的形式总结了本单元的目标语言，即：Where引导的特殊疑问句以及含有on, in, under 的答句。通过3a-3c的学习，学生在新的语境中进一步练习物品位置关系的提问和表述，进一步学习和运用介词on, in, under。3a-3c的活动安排是分层次的。3a让学生看图补全对话，主要关注语言形式（focus on form）,是语言结构练习；3b让学生两人一组看图问答，是控制性的语言输出练习，要求学生输出更为完整的对话；3c是开放性的交际活动（communicative activity），且具有信息差（information gap），是比较真实的语言运用活动，因而更加关注语义（focus on meaning）。
学情分析：本单元的主要内容是谈论物品所在的位置。通过这一话题，训练学生的听、说、读、写四项基本技能。七年级学生已经有了一定的英语语言基础，所以本节课内容并不陌生，让学生通过询问物品的位置，学习一些有关家居物品和学习用品的单词，以及方位介词in, on, under, behind 等的用法；学习并掌握Where问句的问答，一般疑问句提问并用方位介词来回答；学习名词单复数及人称代词、物主代词的用法，同时培养学生养成干净、整洁、合理摆放物品的好习惯。

Step 3 Presentation.
T: Next , let’s play a guessing game.
Look at the picture, what’s this It’s a TV. Now I ask you : Where’s the TV Do you know No. Now we’ll say “I don’t know.” It means“我不知道”. “don’t “ is short for “do not”. If you want to be polite, you can say,” Sorry, I don’t know. “ or “I’m sorry , I don’t know.”
Now I guess ”它是在墙上吗 ” How to say it Is it on the wall No, it isn’t. It’s on the desk.
Then read the dialogue together.
A: Where is the TV
B: I don’t know.
A: Is it on the wall
B: No, it isn’t. It’s on the desk.
Then show the second picture.(The same goes for Picture 2)
A: Where is the cat
B: I don’t know.
A: Is it in the box
B: No, it isn’t. It’s under the table.
（设计意图：设置猜测游戏，教学答语：I don’t know. 由于学生们不知道物品在哪里，所以会启发他们这样说。 而且know 在本节课是个生词。）
Step 4 Practice. (Ask and answer in pairs.)
⑴A: Where’s the computer
B: Is it on the sofa
A: Yes , it is .
⑵A: Where are the baseballs
B: Are they on the chair
A : No ,they aren’t. They’re under the chair.
⑶A: Where are the keys
B: Are they on the desk
A: No , they aren’t. They’re in the desk.
（设计意图：这部分活动是对上部分猜测游戏的延伸，强化学生在不同的情境中灵活地询问物品在哪里。引导学生增加一个答语I don’t know.）
Step 5 Grammar Focus.
1. Translate the sentences and fill in the blanks. (Explain: where’s=where is , where’re ≠where are ) （设计意图：呈现的10个汉译英的句子都是Grammar Focus中原封不动的句子，既是对学生前面知识的检测，又为下面语法的讲解做铺垫。）
2. Show Grammar Focus. Read the key sentences. Boys ask , girls answer.
3. Answer the following questions , according to Grammar Focus.
⑴. ___________和____________用于询问物或人的位置、地点。它是特殊疑问句，不能用yes ,no 来回答。

⑶．如果主语为复数形式, 则be动词用_____,
回答时用_____来代替。
(设计意图：详细讲解语法，让学生们对句型有一个清晰的认识。)
4. Focus on the grammar, sum up the sentence structures.
Where’s +the/my…+n.(单数)？
It’s on/in/under…
Where are the/his…+n.(复数)？
They’re on/in/under…
(设计意图：通过理解语法，让学生自己总结出句型结构，然后教师板书。)
5. Explain how to use the prepositions “on ,in ,under”
Show the pictures and practice.
（设计意图：通过展示关于这三个介词的图片，更加直观形象地再现了它们的用法，易于学生理解。）
Step 6 Practice.
1.3a. (P21) Look at the picture and complete the conversation.
Then read the conversation together. (One half 1 reads A, the other half reads B)
2.3b.( P21) Ask and answer questions about the things on the right.(work in pairs.)
