Grammar Focus
记一记！
what why who when句型结构
what疑问句 What + be动词+主语？
why疑问句 Why+助动词do(does)+主语+谓语？
who疑问句 Who + be 动词+主语？
when疑问句 When + be 动词+主语？
【语法讲解】
特殊疑问句以疑问词开头，常用的疑问词有what, who, when, how等 （因大多数疑问词均以wh-开头，所以特殊疑问句又被称为wh-问句）
◆ who
who作疑问代词， “谁”
对句中表人的主语、宾语或表语提问
Who is in the classroom (提问主语)
Who do you like in your class (提问宾语)
Who is the girl in a red skirt (提问表语)
◆ why
why作疑问副词，“为什么”
用来询问原因或理由
对于why 引导的特殊疑问句，答句通常用because
— Why do you like P.E.
— Because it’s fun.
◆ when
when作疑问副词， “什么时候，何时”
用来询问时间，既可询问某个时段或时刻，也可询问具体的日期
When do you usually have dinner
When is his birthday
◆ what
what作疑问代词， “什么”
多询问某物，可以对句中的主语、宾语或表语提问
What is your favorite sport (提问主语)
What do you have for lunch (提问宾语)
What’s his telephone number (提问表语)
what还可作限定词，和其他名词(如time, color等)一起引导特殊疑问句
What time is it
What color is your bag
语法：关于特殊疑问句结构的分析
小知识：疑问词可以为“特殊疑问词+询问的内容”。
疑问词也可以是“特殊疑问词”本身。
注意1：若陈述句中含有第一人称的人称代词或物主代词，需将其变为第二人称。(I—you, we —you, me — you ,us — you, my —your, mine —yours)
注意2：若陈述句是“情态动词+动词原形”作句子谓语，除了需要将第一人称变为第二人称外，还需要将第二人称变为第一人称。
注意3：陈述句变特殊疑问句不涉及some与any的规则。
学习重点：
1. 特殊疑问句的分类（大类，子类）。
2. 每种分类的结构总结。
3. 做题思路。
做题思路2（非基本句型）
说明：万一要是出现非基本句型，导致无法现场更改和套用，请用下列做题思路。（1,2,3与做题思路1中的相同）
1. 识分类
根据划线位置确定变化后的特殊疑问句的分类。
2. 查人称
检查陈述句中是否有第一人称相关的词。若陈述句中含有情态动词，还需检查是否含有第二人称相关的词。
3. 转中文
将划线部分遮住后，翻译成中文。（翻译时就要记得更改人称）
4. 疑问词
根据划线内容现场判断需选择哪个疑问词。
5. 现场写
根据所背的对应分类的特殊疑问句的结构总结，现场写出答案。
