2. • The Future Perfect expresses the idea
that something will occur before
another action in the future. It can also
show that something will happen before
a specific time in the future.
3. Look at this example
Paul will have given up
playing PS for hours by
the time he gets back
from his vacation.
5. REMEMBER: No Future in Time
Clauses
• Like all future forms, the Future
Perfect cannot be used in clauses
beginning with time expressions such
as: when, while, before, after, by the
time, as soon as, if, unless, etc.
Instead of Future Perfect, Simple
Present is used.
