"prompt": "A detailed illustration of a filtration pool designed to purify water. The pool is set in a lush green environment with trees and plants surrounding it. The pool itself is a large, rectangular structure made of concrete, with clear water flowing through it. The water enters from one end, passes through a series of filters made of sand, gravel, and charcoal, and exits from the other end, visibly cleaner. The filters are depicted with labels showing the different layers of filtration materials. The scene is vibrant and realistic, with natural lighting and shadows to enhance the three-dimensional effect. Ensure no text is included in the image to avoid any potential errors.",
"explanation": "这幅插图展现了一个滤水池的场景，通过详细的画面设计，传达出滤水池的功能和结构。滤水池设置在绿意盎然的环境中，周围环绕著树木和植物，为场景增添了自然的氛围。滤水池本身是一个大型的矩形结构，由混凝土制成，清澈的水流从一端进入，经过沙子、砾石和木炭等多层过滤材料，最终从另一端流出，水质明显改善。这样的设计不仅能够吸引学生和学华语的人士，也能有效地传达“滤水池”这一设施的功能和重要性。",
