The style is realistic and detailed, with a focus on the textures and colors of the wood. Ensure no text is included in the image to avoid any potential errors.",
"explanation": "这幅插图展示了树干的横切面，中央部分是顏色较深的心材，外围是较浅色的边材。树木的年轮清晰可见，从心材向外辐射。背景是茂密的森林景观，阳光透过树叶斑驳地照射下来。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“心材”这一词语的具体含义和自然美感。",
