This document discusses different types of conditional clauses in English grammar: - Zero conditional uses present simple verbs in both clauses to describe situations that are always true. - First conditional uses the present simple in the if-clause and "will + infinitive" in the result clause to talk about possible or likely future events. - Second conditional uses the past simple in both clauses to talk about unlikely or hypothetical events. It provides examples of different conditional structures like if/unless, even if, as long as, providing that. There are also exercises matching conditional structures to situations and rewriting sentences using different conditionals.
