This document discusses Japanese grammar structures using relative pronouns like "when", "where", "why", and "how" to connect two sentences and explain the antecedent. It provides examples of sentences using these structures to talk about remembering a day and describing a country. It also discusses indirect questions where the interrogative word is the object and comes at the beginning of the sentence, and gives examples comparing direct and indirect questions. It assigns practice problems for the students and prepares them for a writing assignment.
