If I didn't have so much work to do,
I would apologize
you would have passed it
if I travelled abroad
I will stay home
If it rains,
If my brother took my things without permission,
If Paul hadn't fall from a tree,
I would send you a postcard
he wouldn't have broken his arm
If I were you,
it boils
I won't let him
If my friend wants to copy my homework,
If you heat water at 100 degrees,
I would go out with my friends
If you had studied for the exam,
I would tell my parents
