Step1 Warming- up and revision

（ 6 分钟）
Step1 Warming- up and revision
1. Greet the Ss as usual. Then check the homework.
2. Go over the conversation in 2e.

Role-play the conversation.

1.The students work in pairs. Suppose Student A is Jane and Student B is Tom. Use the information in 2b to make conversations like that in 2d.
2.Make conversations to talk about Tom and Jane using the information in 2b and the sentence structures in 2d.
Try to recite the conversation and make their own conversations.

Step 2 Presentation
（ 20 分钟）
Read Grammar Focus and discuss the following questions :
1.how， how long， how far 有什么区别？
how对方式状语提问;how long对一段时间或物体的长度提问;how far对距离提问。
2.特殊疑问句和一般疑问句有何异同？
(1)它们的语序相同，都是疑问语序，即主语都在助动词、连系动词be等之后(前/后)；助动词后的谓语动词用原形。
(2)特殊疑问句结构通常为“特殊疑问词(组)+一般疑问句?”。
(3)答语不同(相同/不同)。一般疑问句通常用Yes或No作答;特殊疑问句只能回答所询问的内容，而不能(能/不能)用Yes或No作答。
1. Do some exercises.
2. Ss check the answer with their partners.

3.不同的人称代词分别使用什么助动词？
第三人称单数(he/she/it)作主语，助动词用does；其他人称(you/I/we/they)作主语，助动词用do。

4.“How long does it take to get to school?”—句中it是形式主语，真正的主语是动词不定式短语 to get to school；句中take意为“花费(时间)”,常用句型为“It takes (sb・)some time to do sth.”,意为“做某事花费(某人)多长时间”。
