Your dad was watching a film after dinner. When you came back, he was snoring. Close the examples. Say a Mandarin response, then write it in Chinese. Explain briefly in English what the lesson’s pattern adds. Compare with the model, then change one detail and try again.
This is supported productive practice. Compare meaning and structure; your answer need not copy the model. A partner or teacher must hear the spoken response to comment on pronunciation.
