Future Continuous
A. Use:  a) Use the future continuous to talk about an event that will already be in progress at a specified time in the future.
This time next week, I’ll be driving to my parents’ house.
Phrases often seen with this use of the future continuous include: By ..., This time next week...,  In __ years’ time...; when + present simple; by the time + present simple.
When you arrive, I’ll be driving home. By the time I get home, you’ll probably be having a bath.
b) The future continuous can be used instead of the present continuous for future plans.
Will you be going to Jane’s party? Yes, but I’ll be getting there a bit late, because I’m going to a meeting after work.
c) We can also use the future continuous to make a guess about something that is in progressat the moment.  Don’t phone Richard now, he’ll be having dinner. Oh no, I forgot about the dinner! It’ll be burning, I know it!  These sentences are not about the future but we can use the future continuous to talk about what we assume is happening at the moment. Form: a) You can make the future continuous with will or going to. Make the future continuous this way:
Positive and Negative
I you he / she it we they
will be won’t be
verb + ing


am / are / is    going to be
