If he has money
If I won the lottery
If I drank a lot of water
If she has money
If you see a cat crossing in front of you
If she had been a good student
If I had bought food
she wouldn't have had problems with the teacher.
I wouldn't have been hungry.
I would buy a big house and many cars.
he will travel around the world.
she can buy things.
you will have bad luck.
I wouldn't be thirsty.
