英文問題想問人你係邊到的英文,應該用[where you are]還是[where are you]呢???

Both are right in terms of grammar.
However問人你係邊到grammatically correct should be ''Where are you?''...
''where you are'' usually is after something, for example.
''Stay where you are'' ''tell me where you are''

'Where are you' is the correct way to ask the question
'Where you are' is not proper English

100% 應該是WHERE ARE YOU?
答問題那個就會說 I AM IN XXX(地方)

應該兩個都得..我兩個都聽過...
