The document discusses three types of conditional sentences: first type uses "if" clauses with possible and probable conditions, second type uses "if" clauses with possible but improbable conditions, and third type uses "if" clauses with impossible conditions to express regret over something that could not have happened in the past. Examples are provided for each type of conditional sentence using different verb tenses and structures in the if-clause and main clause.
