Have you,Are you,Do you有咩分別??用係乜野地方???[[[急!!!!!!!!!!!!]]]

have you --- 一定係問你做左d乜野未,係已經發生既事
do you --- 就係問你依家呢一刻做左d乜
are you -- 就完全唔同,有兩種用法:
1)唔係問做左既野,係問所有非動作既野,例如are you serious? are you silly?
2)問發生緊既事,例如are you thinking of me?

如果單純以文法計,do you係現在式,are you係現在進行式,have you係過去完成式

have you done homework
are you doing homework
do you eat lunch
