When do we use Future Continuous?
For actions in progress at a future moment
Future Continuous describes an action that will be IN PROGRESS at a specific moment in the future. It is like a "snapshot" of the future — you can imagine the action happening at that exact time.
Something will be happening at a particular moment in the future.
At 9 am tomorrow, Jake will be climbing the mountain.
in progress at 9 am tomorrow
This time next week, we will be hiking in the mountains.
"this time next week" = future moment
At this time tomorrow, I will be sleeping.
in progress at a future time
An activity that is expected to happen as part of a plan or schedule.
The teacher will be leading us the whole way.
expected ongoing activity
We will be stopping for lunch at noon.
planned activity in progress
"Will you be...?" is softer and more polite than "Will you...?"
Will you be using the car tonight? (polite)
polite question about plans
Will you be joining us for dinner?
polite invitation question
Future Continuous = action IN PROGRESS at a future moment. Future Simple = a completed future action. "At 9 am, I will be hiking." (in progress) vs "At 9 am, I will start hiking." (completed start action)
