给某人举个例子
How do you understand the connection between people, plants, and animals Think of some examples and then share them with a partner.
A: Do you think people, plants, and animals are connected
B: Yes, I do! They need each other a lot. For example, plants make food with sunlight. Then animals like cows (牛) eat plants to grow.
A: Oh right! And people eat cows or plants for energy. That’s a good chain.
B: There’s another example. Bees (蜜蜂) drink nectar (花蜜) from flowers. They carry pollen (花粉) to help plants make seeds.
A: So plants can grow fruits and vegetables for us. And bees make honey (蜂蜜) that we eat too!
B: Exactly. If one part is hurt, others feel it. Like, no plants means hungry animals—and people won’t have enough food.
A: That’s true. We must protect all of them!
