雨林水循环

理解雨林中的水循环过程——树木通过根部吸收水分，并通过叶片将其释放（蒸腾作用），这些水汽在树冠上方形成云，云再产生降雨落回森林，从而形成一个自我维持的循环，产生雨林自身大部分的降雨。

Understand how the water cycle works in a rainforest — trees absorb water through their roots and release it through their leaves (transpiration), this moisture forms clouds above the canopy, and the clouds produce rain that falls back into the forest — creating a self-sustaining cycle that generates much of the rainforest's own rainfall

学习证据 / Evidence

• 描述整个过程：树木吸收水分 → 通过叶片释放（蒸腾作用） → 水汽上升 → 形成云 → 降雨
• 解释雨林通过这一循环产生自身大部分的降雨
• 在描述水分如何通过叶片离开植物时，正确使用“蒸腾作用”一词

• Describe the sequence: trees absorb water → release it through leaves (transpiration) → moisture rises → clouds form → rain falls
• Explain that rainforests generate much of their own rainfall through this cycle
• Use the word transpiration correctly when describing how water leaves a plant through its leaves

{{name}}能解释雨林树木如何帮助形成自己的降雨吗——即通过叶片释放水分，形成云，然后云再化雨落回森林？

Can {{name}} explain how rainforest trees help make their own rain — by releasing water from their leaves, which forms clouds, which rain back down on the forest?
