Выделяется 3 типа Conditional:
1 тип: часть с if употребляется в Present Simple, остальная часть - в Future Simple (употребляется, когда мы говорим о вероятных событиях в будущем и их результатам). Пример: If you study hard you will pass the exam (Если ты будешь учиться усердно, то сдашь экзамены)
2 тип: часть с if употребляется в Past Simple, остальная часть - с Would и глаголом в первой форме (употребляется, когда мы говорим о невероятных или маловероятных событиях в настоящем и будущем). Пример: If I had more money I would buy a car (Если бы у меня было много денег, то я бы купил машину (но у меня нет много денег))
3 тип: часть с if употребляется в Past Perfect, остальная часть с Have been и глаголом в третьей форме (употребляется, когда действие уже совершенно в и ничего исправить нельзя). Пример: If he asked me I would have helped him (Если бы он попросил, то я бы ему но он не попросил)).
