Zero and First Conditional - A2 Exercises
Seven tasks on sentences with if. The zero conditional is for what always happens - if you heat water to 100, it boils. The first conditional is for what will happen if something else does: if I arrive home early, I will do my Science project.
Watch the tenses: after if the verb stays in the present even when the sentence is about the future.
