when is your birthday?how are you?
这里的是什么词性,作什么成分.whree how

when, how在疑问句里都是疑问副词.
你的生日是什么时候?（什么时候: when）
你好吗? （怎么样：how）
这类词多出现在疑问句里,不能充当主语、宾语等.
当它们出现在从句里时,就复杂了.有时充当状语、有时充当表语.
例如：
I didn't tell him when we arrived. (作宾语从句)
This is how I did it. (作表语从句)
How he did it is a mystery. (作主语从句)
He was doing his homework when his mum came home. (作状语从句)
