【设计意图】语法的呈现有利于下一步归纳语法规律。

Step4发现归纳语法规律

1. how可用于构成特殊疑问句，意思为“”，用于提问“程度，方式，状态”等。

How 用于提问出行方式的结构是：How do / does + +谓语+其他？其答语分为三种

情况。

(1) take a / the +

(2) by +表示交通工具的单数名词。

（3）on/in + 限定词+表示交通工具的名词。

2. how long 可用来提问时间的长短，意为“”。用来提问时间长短的结构是： How long

does + +takes?其答语通常用It takes + . 此处的it 指。

3. how far用来提问距离，意为“”。用来提问距离的结构是：How far + +

from…to…?其答语是It’s + . 此处的it 指。

4. 特殊疑问句和一般疑问句的语序有何异同？

5. 不同的人称代词分别使用什么助动词

6. 特殊疑问句中使用了助动词后，实义动词的位置和形式有何变化？

7.看表总结特殊疑问句和一般疑问句的语序。

特殊疑问句：

一般疑问句

(设计意图：各种语言知识的呈现和学习都应该从语言使用的角度出发，为提升学生用语言

做事情的能力服务。语法要在语言运用中习得和内化。教师要通过创设接近实际生活的各

种语境，采用循序渐进的语言实践活动，以及各种强调过程和结果并重的教学途径和方法，

培养学生用语言做事情的能力。语言形式融合在语境之中；在语境中引出语言形式，在语

境中理解语言形式，在语境中操练语言形式。)
