This document contains an agenda for an English lesson that includes three main activities: speaking about food passions, learning expressions to make excuses to decline food, and answering grammar questions about negative yes/no questions. The grammar questions section defines a yes/no question as one that can be answered with "yes" or "no", and explains that the structure is auxiliary + subject + main verb + ? for a positive question and auxiliary + not + subject + main verb + ? for a negative question.
