This book introduces the passive voice structures of be allowed to + verb, be supposed to + verb, be forbidden, be prohibited, and more through familiar warning signs. These signs have already been used in the Vocabulary book to practice the modal verb You can’t.

Throughout the book, young readers transform prohibition sentences using can’t into passive structures like be not allowed to + verb, helping them expand their expressions.

By looking at each warning sign, children practice four key sentence patterns: “Don’t do it here!”, “You can’t do it here.”, “You’re not allowed to do it here.” and “You’re prohibited from doing it.”
