Even if you had called me yesterday, I wouldn't have been able to come.

There were so many people in the hall that I wouldn't have been able to find him.

Even if you had warned me, I wouldn't have had time to see him.

I wouldn't have been able to talk to him, even if I had seen him yesterday.

Even if he had changed a lot, I would have recognized him.

If you were asked this question, would you be able to answer it?

If the station weren't so far away, we would have carried the things ourselves.

He would never have left his friends in trouble, even if it meant risking his life.

If you don't find any of us at home, leave a note.

Even if he hadn't been told anything, he would have guessed what was going on anyway.

If it weren't for time trouble, he could have won the game.

If he starts refusing, I will try to convince him.
