Use Future Continuous (will be + -ing) for actions that will be IN PROGRESS at a specific time in the future. It emphasizes that an action will be happening at a particular future moment.
Quick tip: WILL BE + -ING = action will be in progress at a future time. Use with time expressions: at 3 PM, this time tomorrow, when...
Form: WILL BE + verb + -ING
Positive: I/you/he/she/it/we/they will be working. Negative: won't be working. Question: Will ... be working?
I'll be working tomorrow at 3 PM. (in progress at that time)
She will be studying when you arrive. (ongoing when you come)
They won't be sleeping at midnight. (not in progress then)
Will you be waiting for me? (in progress at future time)
Use 1: Action in progress at future time
Use when you want to say an action will be happening at a specific future moment.
This time tomorrow, I'll be flying to Paris. (in progress at that time)
At 8 PM, we'll be having dinner. (ongoing at 8 PM)
Don't call at 6 - I'll be working. (in progress then)
Use 2: Polite questions about plans
Use Future Continuous to ask politely about someone's plans without sounding demanding.
Will you be using the car tonight? (polite question)
Will they be coming to the party? (asking about plans)
Will you be staying long? (polite inquiry)
Common mistakes
Not "I will work tomorrow at 3 PM." — say "I will be working tomorrow at 3 PM.". Use Future Continuous (will be + -ing) for actions in progress at a specific future time..
Not "I will be work tomorrow." — say "I will be working tomorrow.". After 'will be', use -ING form (gerund), not base verb..
Practise it
Ask: Will the action be IN PROGRESS at a specific future time? Then use Future Continuous!
