Future simple:
I will go // I won´t go // Will you go?
We use future simple to speak about a one-time, unplanned future action:
- The weather will be great in August
- They won´t find the keys
- The guests will arrive after lunch
- Will you come with us?
Future perfect:
I will have gone // I won´t have gone // Will you have gone?
We use the future perfect to refer to actions finished before a future time:
- She will have finished her thesis by august
- They will have had lunch when you arrive
- By the end of this week we will have completed our assignment
Future continuous:
I will be going // I won´t be going // Will you be going?
Future continuous is used to express that an action is in progress at a specific future time
- This time next year, my mother will be enjoying her retirement
- In a couple of hours they will be watching the stars in the performance
