Lesson 35 of Minna no Nihongo II focuses on helping learners expand their vocabulary related to reasons, causes, and explanations. This lesson emphasizes words and expressions commonly used to explain why something happens, give reasons for actions, and justify statements politely in daily and professional situations. Learners are encouraged to practice vocabulary in context, combining verbs, nouns, adjectives, and polite expressions to create natural sentences suitable for conversation. Strategies include repetition, practicing dialogues, role-playing scenarios, and integrating new words into personal routines, which strengthen comprehension and practical usage. Practicing Lesson 35 vocabulary allows learners to communicate effectively about reasons, provide explanations politely, and enhance conversational skills, forming a strong foundation for real-life Japanese communication.
