Zero conditional: if + present simple, present simple for facts and habits
Use the zero conditional for things that are always true: facts, rules and habits. The form is if + present simple, present simple in both parts (If you heat ice, it melts.). It means 'every time this happens, that happens', so you can often use when instead of if (When I'm tired, I go to bed early.). The if part can go first or second; when it goes first, put a comma after it (If it rains, we take the bus. / We take the bus if it rains.). Don't forget the -s with he, she and it (If my dog sees a cat, he starts barking.) and use don't/doesn't for negatives. A common mistake is to use will after if: say 'If it rains', not 'If it will rain'.
