The style is realistic yet soft, with gentle brush strokes and a harmonious color palette. Ensure no text is included in the image to avoid any potential errors.",
"explanation": "这幅插图展现了一只优雅的白天鹅在平静的湖面上滑行的场景，周围环绕著茂密的绿植和清澈的蓝天。天鹅的长颈和纯白的羽毛在水面上形成了柔和的倒影，背景中的芦苇和睡莲增添了自然的氛围。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“白鸟”这一词语的优雅和自然之美。",
