Will, Will Be Doing, or Will Have Done? Exercise 2
level: Advanced (C1)
A second exercise on choosing the right future form, with shorter but trickier sentences. This one focuses on will for promises and strong refusals, the once/after trigger for the future perfect, and cases where the continuous and simple forms are easily confused. If you haven't done exercise 1 yet, start there.

Future forms — nuance and trickier cases
This exercise goes beyond the basic signal words. Here are the patterns that catch learners out at C1 level.
WILL for promises, strong decisions, and refusals:
Will carries emotional weight in these contexts — it expresses the speaker's commitment or strong stance.
I'll never speak to her again! (strong refusal)
She doesn't realise it yet, but she'll find out. (confident prediction)
These are simple future, not continuous or perfect, because the focus is on the speaker's stance rather than the timing or completion of the action.
ONCE / AFTER → future perfect:
Once and after can trigger the future perfect just as by the time does — they signal that one action will be complete before another begins.
After we finish this video, I'll have watched all his films.
Once the repairs are done, they'll have spent over €5,000.
Scheduled appointments: will or future continuous?
For fixed arrangements at a specific time, simple future is natural and correct.
I'll see you tomorrow at 3. (appointment — will see is fine)
Future continuous stresses the ongoing nature: I'll be painting all day tomorrow (throughout the day).
Won't vs will not have / will not be:
A flat refusal or simple negative prediction uses won't + base verb.
She won't tell me when her birthday is. (refusal/habit)
She won't have told me implies a completed state — a different and rarer meaning.
