📖 Grammar Reference — will be doing and will have done
Study the notes, then work through the six exercises.
A will be doing — in progress at a future time
Use the future continuous for an action that will already be happening at a certain moment in the future. Picture the clock: at that time, the action is in the middle of happening.
| At a future time | This time tomorrow I‘ll be flying to Paris. |
| Don’t interrupt | Don’t call at 8 — we‘ll be having dinner then. |
| Polite question | Will you be using the car tonight? (= are you planning to) |
💡 Compare: At 9 o’clock I will start work (the start) vs At 9 o’clock I will be working (already in the middle of it).
B will have done — finished before a future time
Use the future perfect for something that will be completed by (= before or at) a moment in the future. It often comes with by + time, or by the time + clause.
⚠️ After will have, use the past participle (done, finished, left, written) — never the base or the -ing form.
C Continuous or perfect? Spot the difference
Ask one question: at that future moment, is the action still happening, or is it already over?
