If everyone had clean water to drink,
If they didn't understand the problem,
If she drank too much coffee,
If I had a spare ticket,
If I were fit,
If there were no hungry people in this world,
If he were a millionaire,
If the weather were sunny,
If I weren't in a hurry,
If she were in your position,
they wouldn't find the solution.
she wouldn't feel calm.
she would be able to advise you.
he would buy you a palace.
there would be a lot less disease.
I would stay to dinner.
I would go climbing.
I could take you to the concert.
it would be a much better place.
we wouldn't stay indoors.
