The document explains the first conditional, which is used to talk about possible situations in the present or future. It provides examples of conditional sentences using "if" clauses and main clauses with "will" to express possibilities. Key points are that the first conditional discusses what may happen, with an "if" clause referring to a possible present or future condition, and a main clause with "will" referring to the possible present or future result.
