Answers and explanation:
In the exercise that we’re asked to complete we have a special kind of sentences in Spanish: CONDITIONAL SENTENCES. But what are those?
They are those sentences that express an action that only can be possible if a condition or requirement is previously satisfied. So, in conditional sentences, we always are having a CONDITION and a CONSEQUENCE.
EXAMPLE:
Si comes mucho serás gordo (If you eat a lot you will be fat)
CONSEQUENCE: Ser gordo (be fat)
as we can see, in conditional sentences we always are having a special word (conjunction) that indicates the conditional feature of the sentence. This word is SI and it works as the English word IF.
We also can conjugate the verbs in all the moods, tenses, voices and numbers that we want, we just have to recognize the syntactical structure:
*Please notice how we can select any conjugation form, but it exists a relation between the two conjugated verbs*
