语言学习 CEFR 进阶路径图

一张阶梯式信息图，以等轴测扁平矢量插图展示语言学习 CEFR 从 A1 到 C2 的进阶路径，暖象牙色背景。六个上升的等距平台台阶层层叠加，每级从底部较宽到顶部较窄。每级台阶颜色各异：浅天蓝（A1）、浅青（A2）、暖琥珀（B1）、金橙（B2）、珊瑚红（C1）、深酒红（C2）。每级顶面标注级别（如 「A1 Beginner」）和小图标：小鸡（A1）、嫩芽（A2）、树苗（B1）、小树（B2）、大橡树（C1）、山顶旗帜（C2）。每级竖面前壁列出四项技能：口语、听力、阅读、写作，附大致词汇量。台阶上有小型插图人物攀爬。右侧索引显示各级别预计学习时长。

A staircase-style infographic representing the CEFR language learning progression from A1 to C2, designed as an isometric flat-vector illustration on a warm ivory background. Six ascending platform steps are stacked like an isometric staircase, each wider at the bottom and narrower at the top. Each step is a distinct color: pale sky (A1), light teal (A2), warm amber (B1), golden orange (B2), coral red (C1), deep burgundy (C2). On the top face of each step, the level label (e.g., "A1 Beginner") sits in bold type alongside a small icon: a baby chick for A1, a seedling for A2, a tree sapling for B1, a growing tree for B2, a full oak for C1, and a summit flag for C2. On the vertical front face of each step, four bullet skills are listed: speaking, listening, reading, writing, with approximate vocabulary counts. Tiny illustrated figurines climb the staircase. A right-side key shows estimated study hours per level.
