对句中某一成分提问的句子，就叫特殊疑问句。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。
疑问词按词性可以分为疑问副词和疑问代词。
疑问词有what, who, why, when等。
疑问代词：what, who
疑问副词：when, why
特殊疑问句
①可单独用于询问姓名、年龄、号码、计算结果、物品等。
例：What’s your name
②也可与其它名词subject, food, color等“组合”询问更为具体的信息。
例：What color does he like
what作疑问代词，意为“什么”。用于询问“某物/某事”。
who作疑问代词，意为“谁”。用于询问“某人”，在句中可作主语、宾语、表语。作主语时，谓语动词多用单数形式。
whom意为“谁”，只在句中作宾语；
whose意为“谁的”,只在句中作定语。
例：Who is in the classroom (作主语)
Who/Whom are they talking with (作宾语)
when作疑问副词，意为“什么时候；何时”。用于询问年、月、日、星期这样的时间。
例：—When is your birthday
—It’s on June 5th.
why作疑问副词，意为“为什么”。用于询问原因时，用because引导的句子回答，意为“因为……”。
例：—Why do you like P.E.

特殊疑问句的构成
特殊疑问句一般由“疑问词+一般疑问句 …？”
构成（提问主语部分的疑问句除外）。
例：Why do you like P.E.
How do you spell it

1.特殊疑问词放在最前面；
