If you get there early, you'll get the best seats
If I need your help, I'll phone you
If the bus doesn't come, we'll take you in our car
If it rains tomorrow, we won't go to the park
When Jo and Mike arrive, I'll offer them a, drink
When the train stops, the doors will open
When we go into town, we'll have lunch there
When the course finishes, I'll go back to Japan
