Have your lesson ??

1Where will you have your lesson?
你嗰堂會喺邊度上?
將來式,即係唔理你e+有冇上堂,佢講緊將來嘅某一堂上堂嘅地方.

2 Where do you have your lesson?
你平時喺邊度上堂?
現在式,即係唔理你將來會唔會上,平時每1日上堂嘅地方.

3 Where are you have your lesson?
文法錯,可以改成:Where are you having your lesson?
你e+喺邊度上緊堂?
現在進行式指講嘅時候發生緊嘅事,或者一段時間都有做嘅事,例如安排/組織一個活動,要一星期/一個月.

文法: are/is/am/were/was,只可以+ing(進行式),或+ed(過去式被動語態)

The first question is grammatically correct. It is in the simple future tense.
The second question is also grammatically correct. It is in the simple present tense.
The third question is wrongly asked. One does not put two finite verbs together in a
sentence or a question. "Are" and "have" are such finite verbs.

他們應該係個tence唔同

Where are you have your lesson?
It should be Where are you going to have your lesson?

Well... they are correct

Where will you have your lesson?
Where are you going to have your lesson?
These two are same.
They are asking people the place they will have for the lesson
they have not been to the place before
this will be the first time

But
Where do you have your lesson?

it means you have gone there at least once
it is a habit
you always go there for your lesson.


Hope I can help you!
