*We use the
future continuous (will/shall+ be+ -ing) to
say that an action will be in progress at a definite time in the future.
Example: I'll be living in my own apartment by this time next year.
And
*We use the future perfect (will/shall + have+ past
participle) to describe something that will be completed before a definite time in the future (unit 1 and 2)
