### **题目:**
**According to the passage, the island got its first soil from _______.**
(根据文章,这个岛屿最初的土壤来自哪里?)

### **分析:**
根据文章内容:
- “hot sun and cool rains made the rock split and break to pieces.”
→ 阳光和雨水使岩石破裂。
- “Sea waves dashed against the rock. In this way, soil and sand came into being.”
→ 海浪拍打岩石,这样形成了土壤和沙子。
也就是说,**岩石在自然力量(阳光、雨水、海浪)的作用下破碎,最终形成了土壤**。所以,**最初的土壤是岩石破碎形成的**,也就是来自于“its own rock”。

### **选项分析:**
- **A. its own rock(它自己的岩石)** ✅ 正确。岩石破碎后形成了土壤。
- B. the sand brought by the wind(风带来的沙子) ❌ 文中没有提到风带来沙子。
- C. cool rains(凉爽的雨水) ❌ 雨水只是让岩石破裂,并不是土壤的直接来源。
- D. sea waves(海浪) ❌ 海浪只是帮助岩石破碎,不是土壤的来源。
