Conditionals

When the film ... , I will help my grandparents.

If I ... free time, I will go to the castle.

If you ... with me, you will get lost.

Unless they ..., they won't catch the last bus.

As soon as they ...in Paris, they will go on a city tour.

If she .... to the concert, she would have been upset.

If I ... you, I would call the police.

If I knew him, I... him to my party.

If I didn't have any friends, I ... miserable.

What ... you do if you lost your key?

What .... you do if you stay in Madrid for a week?

... we stop cutting down the trees, lots of animals will die.
