探究一、知识链接
特殊疑问句
定义：是以特殊疑问词开头，提出疑问的句子，也称wh-问句。
构成：特殊疑问词 + 一般疑问句
注意：若疑问词作主语，特殊疑问句的语序则用陈述句语序。
常见的特殊疑问词包括：what（什么），who（谁），whose（谁的），when(何时)，why（为什么），where（在哪里），what time（问时间），how（如何，怎样），how old（多大），what color（什么颜色），how much（问价格&数量多少），how many +ns(问数量多少)，what subject （什么学科）……
在特殊疑问句中，疑问词与后面的be动词或助动词常用缩略形式，如what’s，where’s.
特殊疑问句既可以使用完整答语，其中名词常用代词替代，也可以只回答提问部分。
探究二、基础探究
观察下列句型并仿写例句。
What’s your favorite subject?
=What subject do you like best? My favorite subject is P.E.
=I like P.E. best.
What’s her favorite subject?
=What subject does she like best? Her favorite subject is art.
=She likes art best.
What’s his favorite subject?
=What _______ does he _______ ________? His favorite subject is math.
=He ________ math ________.
What’s Tom’s favorite subject?
=What ________does ______ ______ _____?
Tom’s favorite subject is science.
=__________________ ___________________
What’s Linda’s favorite subject?
=_____________________________________ Linda’s favorite subject is geography.
=_____________________________________.
发现：
What’s sb’s favorite subject？ =_______________________________
Sb’s favorite subject is.... =_____________________
特殊疑问句结构为：特殊疑问词+一般疑问句
若句中有be动词时，结构为:特殊疑问词+_______________+主语+其他?
若句中有助动词时，结构为：特殊疑问词+_____/______ +主语+_____________+其他？
【小牛试刀】
1. —_______ _________she like Chinese? ——Because it’s interesting.
2.—_________ ________ your birthday? — On May 3rd.
探究三、知识详解
because，but与so的辨析
(1)because意为“因为”，表示原因，常用于回答why引导的特殊疑问句；也可用于连接两个具有因果关系的句子。
(2)but意为“但是”，表示转折关系。
(3)so意为“因此”，表示因果关系，注意so与because不能同时出现在句子中。如：
The music is fun，so she likes it.＝She likes music，because it's fun.
