It provides examples of how to structure sentences using the zero conditional, which uses the present simple tense in both the if-clause and main clause.

2. Remember!!!
Conditionals have two parts:
An if clause and a main clause.
When the if clause comes first, we use a
comma between the two clauses.
When the main clause
comes first, we don't use
a comma.
