1) If we owned a boat, we would have to go sailing in the Mediterranean.
2) I would feel nervous if i had to appear on television.
3) If you apologised to Paul? he wouldn't be so angry.
4) If we hadn't wars? the world would be much better.
5) More people would go to that cafe if they served nicer food.
6) I wouldn't go to the leisure center if it hadn't a swimming pool.
