revolve 常指绕外部中心旋转（如地球公转），语体较正式；口语中很少描述球体贴地滚动。
spin 强调快速原地旋转（如陀螺），不包含沿地面移动；说“车轮spin”重在转速，roll 则客观描述滚动。
tumble 常含失去平衡、向下翻滚或杂乱之意，语气比 roll 更生动；roll 可中性描述正常滚动。

易错句子She rolled the steering wheel to the right.
正确表达She turned the steering wheel to the right.
汉语的“转”既能表示“滚动”，也能表示“旋转、转动”，所以学习者容易一律用 roll。roll 指物体表面贴着另一表面滚动的移动方式；而方向盘、钥匙、旋钮等绕轴转动的动作要用 turn，因此把 rolled 改成 turned。

正确表达He rolled up his sleeves and started to work.
