What students need to know
We use this to talk
about what’s possible, given certain conditions. The speaker sees whatever it
is as a distinct possibility, not a remote one. A very similar structure is
used with sentences that are not technically conditional:
When you grow up,
you’ll understand.
Unless you grow up,
you won’t get any pie.
After you do the
washing up, we’ll see about getting a
rabbit.
