Auxiliary verb of present progressive used to describe future

[lycen]

Hi, I need help on the following:

They leave tomorrow ("leave" refers to the future; future action)

They are leaving tomorrow (Does "are" refer to his future state i.e. tomorrow/time of action and not his present state i.e. at the time of speaking or is it the other way around?)

Thank you.

as far as I know there two expression to show it
1. They will leave tomorrow. It indicates that they have an ideal to leave tomorrow, but not sure exactly.
2. They are going to leave tomorrow, it indicates that they have a fix plan to leave.
3. They will be leaving tomorrow at this time. We know the proses of leaving tomorrow in the same time when someone say it.

They leave tomorrow ("leave" refers to the future; future action) No, this is in present tense. The word tomorrow gives it its future sense.

They are leaving tomorrow (Does "are" refer to his future state i.e. tomorrow/time of action and not his present state i.e. at the time of speaking or is it the other way around?) No, the -ing in "leaving" gives you the duration of action. That durative action is brought to the future once again by the word "tomorrow".

Hope that helps.
