zero A
if you heat water 100°C
it boils
If it rains tomorrow
we will stay at home
If I won the lottery
I would buy a house
If i had studied harder
I would have a better job now
if you touch fire
you get burned
If you study hard
you will pass the exam
If she were taller
she would play basketball
If she had woken up earlier
she wouldn't be late
if you mix blue and yellow
you get green
If she calls me
I will answer
If we had more time
we would go on vacation
If they were more careful
they wouldn't have had accident
if you freeze water
it turns into ice
If we leave now
we will arrive early
If I were rich
if the sun sets
it gets dark
If you get too much
you will feel sick
If the trained harder
they would win the championships
