He wouldn't have arrived late
If we had known about Dan's allergy.
Dad would be angry
If I were you,
If he knew the results,
I won't go unless
If you climb that tree,
If I hadn't eaten so much
you come with me
I wouldn't tell Andy
if he saw you now
we would have helped him
I wouldn't have felt sick
you will feel dizzy
he wouldn't hide them
if he had left on time
