A look at seven ways of expressing the future in English. If we want to refer to future-time situations we can do this in several ways.

Simple prediction: There will be snow in many areas tomorrow.
Arrangements: I'm meeting Jim at the airport.
Plans and intentions: We're going to spend the summer abroad.
Time-tabled events: The plane takes off at 3 a.m.
Prediction based on present evidence: I think it's going to rain!
Willingness: We'll give you a lift to the cinema.
An action in progress in the future: This time next week I'll be sun-bathing.
An action or event that is a matter of routine: You'll be seeing John in the office tomorrow, won't you?
Obligation: You are to travel directly to London.
An action or event that will take place immediately or very soon: The train is about to leave.
Projecting ourselves into the future and looking back at a completed action: A month from now he will have finished all his exams.
