If Mary doesn't like the present
If I study hard
I WON'T PASS THE TEST
YOU WON'T GO OUT ON FRIDAY
If River wins
SHE WILL CHANGE IT
If she has money
WE WILL HAVE A PICNIC
If I don't study
If my brother washes the dishes
SHE WILL GO SHOPPING
I WILL PASS THE TEST
If it doesn't rain
If you don't eat your pizza
WE WILL CELEBRATE IT
If John calls
WE WON'T HAVE A PICNIC
I WILL HELP HIM
I WILL TALK TO HIM
If it rains
