See our complete lesson about Zero Conditional as a part of our free English course.
When we are thinking about facts which are generally true, we use:
If + Present Simple, Present Simple
- If you put water in the freezer, it becomes ice.
- If you stand in the rain, you get wet.
- If you heat ice, it melts.
You can see in the examples about the condition always has the same result.
Notice how we use a comma after the first present simple tense clause.
We can also reverse the order and use:
Present Simple + If + Present Simple
- You get wet if you stand in the rain.
- Ice melts if you heat it.
- I can't sleep if I drink coffee at night.
- Plants die if you don't water them.
Notice how the comma is not necessary with this word order.
