Design a vertical bilingual English-Chinese reading textbook infographic on the topic of "[Topic]". The overall design should adopt the editorial style of classic English textbooks and supplementary readers, referencing the professional layout of 20th-century publications. The layout should be formal, clear, and aesthetically pleasing, providing the reading experience of a traditional printed textbook. Maintain a fixed textbook layout structure that does not change its logic based on the topic; visual style, illustration style, and cultural elements can be adjusted according to the article content. At the top of the page, include a concise course header, chapter label, or reading level information. Place a prominent English main title "[English Title]" in the center, with a smaller Chinese title "[Chinese Title]" underneath. The main body area should focus on the English reading passage, divided into 3 to 5 short paragraphs with natural and concise language suitable for primary and secondary school students. Use a limited amount of accent color within the text to highlight key vocabulary or grammar points, while maintaining a restrained and professional printed textbook feel. Use a modular editorial layout typical of classic English reading textbooks: place the English reading text on the left or upper half, and a main thematic illustration on the right. The bottom of the page should feature fixed learning support sections, such as "Chinese Translation," "Key Words," "Did You Know?," and "Think and Answer." The boundaries between text areas, illustration areas, and exercise areas should be clear, with a natural reading path suitable for classroom teaching and printing. The main illustration content should vary according to the topic, such as character stories, natural science, historical events, urban life, traditional culture, scientific exploration, the animal world, or travel scenes. Include 1 to 2 smaller supplementary narrative illustrations to provide background information or highlight key plot points. The illustrations should use a classic hand-drawn publication style, selecting a visual language appropriate to the topic, such as watercolor, light wash, pen and ink, vintage picture book, natural history illustration, or realistic textbook illustration style. Characters, animals, objects, and environments should be structurally accurate and naturally rendered, avoiding exaggeration, childishness, or modern 3D cartoon effects. The overall color palette should be adjusted according to the topic while maintaining a low-saturation, soft, and printed-texture textbook style. Use off-white, light gray, or aged paper tones as the base background, paired with accent colors like dark blue, forest green, brownish-red, terracotta, or charcoal gray; avoid high-saturation, clashing colors. The background may include very subtle textures, environmental elements, or thematic decorations, provided they do not interfere with text legibility. Fonts and layout should remain classic, rational, and professional: use a bold, clear serif font or a classic textbook title font for English titles, and a highly readable printed typeface for the body text. Chinese titles and auxiliary text should be concise and standardized. Avoid fancy artistic fonts, modern commercial poster styles, or excessive decoration. Overall requirements: Fixed English textbook infographic layout + content and illustration style that varies by topic. Maintain a rich information hierarchy without overcrowding, with reasonable white space, neat margins, balanced text-to-image ratio, and a professional publication quality, suitable for use as single-page English reading materials, classroom handouts, or cultural science reading pages. Vertical orientation, 3:4 aspect ratio, high resolution, complete page design, classic English textbook layout style, clear visual hierarchy, standardized editorial layout.
