雨林分层
Rainforest Layers
知道热带雨林从地面到天空分为四个层次——森林地表（阴暗、潮湿，布满腐烂的树叶）、林下叶层（阴影中的小树和灌木）、树冠层（由树冠组成的厚厚屋顶，大多数动物生活在这里）以及露生层（最高的树高耸于树冠层之上，沐浴在明亮的阳光中）。
Know that a rainforest has four layers from ground to sky — the forest floor (dark, damp, full of decomposing leaves), the understory (small trees and shrubs in the shade), the canopy (a thick roof of treetops where most animals live), and the emergent layer (the tallest trees poking above the canopy into bright sunlight)
学习证据 / Evidence
- 按从地面到天空的顺序说出雨林的四个层次：森林地表、林下叶层、树冠层和露生层。
- 描述每个层次的一个主要特征，例如树冠层是厚厚的树叶屋顶，或者森林地表阴暗潮湿。
- 解释大多数雨林动物生活在树冠层的原因，因为那里有食物和阳光。
- Name the four rainforest layers in order from ground to sky: forest floor, understory, canopy, emergent
- Describe one key feature of each layer, such as the canopy being a thick roof of leaves or the forest floor being dark and damp
- Explain that most rainforest animals live in the canopy because that is where there is food and light
评估问题 / Assessment
如果{{name}}来画一片热带雨林，能表现出四个层次吗——阴暗的森林地表、阴凉的林下叶层、枝叶繁茂的树冠层，以及刺向天空的最高露生树？
If {{name}} draws a rainforest, can they show the four layers — the dark forest floor, the shady understory, the leafy canopy, and the tallest emergent trees poking into the sky?
