This document discusses the first conditional in English grammar. It explains that the first conditional uses the present simple in the if-clause and will + infinitive in the main clause. Examples are provided such as "If I finish my homework early, I will go to the cinema with my cousin" and "If I doesn't study, I won't go to Girona." The order of the clauses can be reversed. Present simple verbs, future will/won't, and examples of the full first conditional structure are defined.
