Audio script
Welcome to Amazing Life. Let's look at these fish from Africa.They are lungfish. They have lungs and can breathe air. They can live without water for months. OK. Next, let's...
Sorry, but could you explain a little more How do lungfish stay alive
In the dry season, they go into the wet earth and sleep. And in the rainy season, they go back into the water.
Thanks.
Let’s look at these pictures. Scientists are doing research on lungfish. They study their bodies and behaviour.

Guide:
Excuse me. Why do they study lungfish
Scientists believe that people developed from fish. So this study can help humans understand themselves. Now, let’s...
Sorry, sir. Did you say people developed from fish
Yes. Long ago, some fish left the sea. They grew lungs and walked on the land. Lungfish are like those fish.
Wow!

Learning to learn
Interrupting politely When someone explains something, you might want to ask a question. You can interrupt politely with Excuse me or Sorry. Don’t interrupt people in the middle of a sentence.
Post-listening
Are you amazed by the amazing life What other amazing life do you know
What are they What do you know about them
earthworm
sensitive plant
Shaek
蚯蚓
含羞草
鲨鱼
earthworm
sensitive plant
Shark
蚯蚓常栖息于温度较高、腐殖质较多的表层土壤中。昼伏夜出，对光线非常敏感，在干燥环境集抱成团，不吃不动，以减少消耗。蚯蚓以腐烂的落叶、枯草、蔬菜碎屑等有机物为食。
含羞草在受到外界刺激时，叶柄下垂，小叶片合闭，叶片迅速移动响应外界刺激，这种叶片动作被人们理解为是含羞草在“害羞”，由此得名含羞草、知羞草、怕丑草。
鲨鱼以海洋中的鱼类、甲壳类等为食，是海洋生态系统中重要的顶级掠食者，对维持海洋生态平衡有着关键作用。
Work in pairs. Ask and answer about another amazing life.
