I should have missed the train if I had not run to the station.

If I were you, I would reconsider my decision.

If my mother were a stewardess, she would travel the world for free.

If I had money about me, I would have bought that new jacket.

If we had spare time, we could explore the city more.

If it had been warm yesterday, I would have gone to the beach.

If the weather were fine today, we could have a picnic in the park.

We should join our voyage if we can find a reliable captain.
