This document discusses how to form interrogative sentences to get confirmation from others in a conversation. It explains that interrogatives are formed either by inverting the subject and auxiliary verb, such as "I am a boy" becoming "Am I a boy?", or by adding "do", "does", or "did" when there is no auxiliary verb, like "I work hard" becoming "Do I work hard?".
