If I had a beautiful voice, I'd sing in a band
If I found much money, I'd buy a motor-bike
If I were an adult, I wouldn't go to school
If I didn't eat cakes and ice cream, I'd lose weight
If I didn't go to bed late, I wouldn't oversleep in a morning
If I didn't lose my watch, I wouldn't be late for the lessons
If I had much time, I'd learn another language
