Zero Conditional is used to express [a general truth|the probable future].
In the if/when-clause we usually use [Present Simple|Future Simple].
In the main clause we usually use [Present Simple|Future Simple].
In this type of conditionals, we [can|cannot] use "when" instead of "if".
"Unless" means ["if"|"if not"].
When the main clause comes before the if-clause, we [use|do not use] a comma between them.
