Don't go out until...
I refuse to pay anything...
I like to keep fit so...
He has good qualifications..
I haven't seen her but...
The film was boring so..
He practised hard because..
My father rang me because..
If she phones...
She felt ill so...
  you've finished your work.
  until the job is finished.
  I go jogging.
  but he can't get a job.
  I know she is well.
  I left early.
  he wants to be in the team.
  he was worried.
  tell her I'm out.
  she went home early.
