Use a minimalist white-space style, with overall visuals featuring large whitespace, low-saturation colors, and a few lines and icons.

Titles should be clear, body text specific, suitable for formal presentations, reports, or external communication. Suitable for student presentations, with a natural and confident tone, content like a real classroom presentation or campaign speech. Page structure can refer to: 1. Cover: course theme and applicable grade 2. Learning objectives: knowledge, skills, and literacy goals 3. Context introduction: problems, images, or case studies 4.

Each page must have a clear title, body content, and complete layout; when charts, flowcharts, timelines, comparison tables, classroom activities, or case analyses are needed, fill in content directly related to the topic, not just placeholder descriptions. Reasonable class, company, project, or character names can be used, keeping consistency.
