Olá Alessandra. Poderia enviar a dúvida completa? Está faltando parte do exercício.

Hello Alessandra

The question you asked is incomplete, however, I think that I may still be able to help by explaining the '0 conditional'

The '0 conditional' If formed by using the if (clause)+ present and the complimentary / secondary clause is also expressed in the present. 

The 0 conditional requires that a repeated condition is met for a result or outcome to be met also expressed in the present (regularily). Both clauses use the present. This is why in the examples, I use adverbs to show the action in repeated or continous (everyday / each night etc. )

For example:

If you take a multivitamin everyday, you stay healthier.

If you get at least 8 hours of sleep each night, you don't feel tired.

7) Read again the sentence in green it is a zero- conditional sentence. but it differs a bit from the examples we have seen so far the difference is that. A) The sentence is formed by if- clause + imperative. B) The if- clause does not express a condition.
