We can refer to the future by using will, be going to or by using present tenses. We use the will future when we want to talk generally about future beliefs, opinions, hopes and predictions.
I promised myself that once I start college I will do all my assignments on time
The will future is formed with the infinitive without to. Questions are indicated by inverting the subject and will. Negatives are formed with will not (wont't).
(+) Sam will probably move to Canada next year
(-) Sam won't move to Canada next year. He will move to the US (?) Will Sam move to Canada next year? / Where will Sam move to?
Note that in speech and informal writing will is usually shortened to 'll.
He'll move to the US
Some time markers can show when we expect something to happen (tomorrow, next month, in a day etc.) or how certain or uncertain we are about our predictions (perhaps, probably, definitely, certainly etc.).
Perhaps it'll snow tomorrow
I'll definitely finish my essay next month
Note that such time markers as probably, definitely, certainly come after will but before won't.
We'll probably do it tomorrow
We probably won't do it tomorrow
Some speakers use shall to refer to the future in formal situations with I and we. However this use is becoming very rare. Nowadays shall is used for suggestions only.
