[聚焦一] 一般疑问句和特殊疑问句的定义

特殊疑问句是以特殊疑问词开头，对陈述句中的某一部分提出疑问的句子。朗读时常用降调。
[聚焦二] 一般疑问句和特殊疑问句的构成及应答。
一、 一般疑问句
1. 含有系动词be或情态动词的陈述句，变为一般疑问句：I'm a policeman. → Are you a policeman? I can help you. → Can you help me?
2. 若陈述句的谓语动词是行为动词：He likes to play football. → Does he like to play football?
3. 一般疑问句的应答。回答时，注意采用相应的人称代词以避免重复，否定回答时还要注意缩写，不过am与not不能缩写为amn't。如：
① -Is he a student?
-Yes, he is.
② -Can you speak English?
-No, I can't.
③ -Do you like singing?
-Yes, I do.
④ -Would you like to come to my home?
-Yes, I'd love to.
二、 特殊疑问句
1. 特殊疑问句的构成："特殊疑问词+一般疑问句"。如：How old are you?
2. 特殊疑问句的应答不用"yes/no", 应作具体回答。如：
-What time is it, please?
-It's 7:30 a.m.
3. 特殊疑问句中的疑问词的选用是最关键的。那么特殊疑问词有哪些呢？
① 疑问代词可在疑问句中作主语、宾语、表语和定语。常见的有：what，who，whose，which等。
如： -What colour is it? -It's red.
② 疑问副词可在疑问句中作状语、定语。常见的有: when，where, how，how many，how much, how tall，how old，why等。如：
A. -How tall are you?
-I'm 1.60 meters.
B．-How far is it from here to your home?
-It's 30 kilometers away.
