This document provides exercises to practice rewriting sentences using conditional statements. The exercises include rewriting sentences to replace "if" with "unless" and vice versa. They also involve rewriting sentences starting in a specific way to maintain the same meaning. Finally, there are exercises to rewrite sentences using the second or third conditional to change the time frame being discussed. The goal is to practice using conditional statements to effectively convey conditional meanings.
