特殊疑问句
就句子中的某一部分提问的疑问句，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
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
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……”
