结构适应
了解动物具有结构适应（身体特征，如长颈鹿的长脖子、鹰的利爪、海豚的流线型身体）、行为适应（迁徙、冬眠、使用工具）和生理适应（北极鱼类血液中的抗冻蛋白、蝙蝠的回声定位），并且这些适应是经过许多世代通过自然选择发展而来的。
Understand that animals have structural adaptations (body features like the giraffe's long neck, eagle's talons, dolphin's streamlined shape), behavioural adaptations (migration, hibernation, tool use), and physiological adaptations (antifreeze in Arctic fish blood, echolocation in bats) — and that these developed over many generations through natural selection
学习证据 / Evidence
- 能将适应定义为帮助动物在自身环境中生存的特征或行为。
- 能举出结构适应、行为适应和生理适应的例子。
- 能说明适应是经过许多世代发展而来的，而不是在某个动物的一生中形成的。
- 能初步将适应与自然选择的概念联系起来。
- Defines adaptation as a feature or behaviour that helps an animal survive in its environment
- Gives examples of structural, behavioural, and physiological adaptations
- Explains that adaptations develop over many generations, not during one animal's lifetime
- Connects adaptations to the concept of natural selection at a basic level
评估问题 / Assessment
如果{{name}}看到一只啄木鸟在啄树，能否说明它坚硬的喙、长长的舌头和防震的头骨都属于适应，并结合其他例子解释“适应”一词的含义？
If {{name}} sees a woodpecker pecking a tree, can they explain that its strong beak, long tongue, and shock-absorbing skull are all adaptations — and describe what the word 'adaptation' means with other examples?
