If you go to St.
Petersburg in June, you will see the white nights.
When this museum is open, we
will go for an excursion there.
I’ll buy that novel as soon as
it comes out.
After I leave school, I'll
enter the University.
Once he returns from work,
I'll ring you up.
I won’t leave until you come.
While I'm in Milan, I'll go
shopping.
Before I go for a walk, I'll
have to do my homework.
I'll wait in the office till it stops raining.
