2 Second conditional
If + past followed by would is used when we want to imagine the consequences of events that are unlikely to happen or events that can't possibly happen:
Which country would you visit if you could go anywhere in the world?
-If I had enough money, I'd go to Brazil.
If you had $1,000 to spend, where would you spend your holiday?
If I was (or were) English, I wouldn't neet to take this exam.
In some situations, we can use either type, depending on what we mean exactly:
I would go to the USA if I had enough money. (but i haven't got enough)
I'll go to the USA if I manage to save up enough money. (more optimistic)
If I pass my driving test first time, I'll think about buying a car. (more confident)
If I passed my driving test first time, I'd think about buying a car. (less confident)
If I were you is often used for giving advice:
What would you do in this situation?
- If I were you, I'd stay at home.
