zero conditional
We use the so-called zero conditional when
the result of the condition is always true, like
a scientific fact.
If you heat ice it melts.
The important thing about the zero conditional is that the condition always has the same result.
We often use when instead of if, for example:
When I get up late, I miss my bus.
We can use unless=if (I/he/you)don't/doesn't +V1
Unless he asks you politely, refuse to do any more work on the project.
