Imagine you go to the supermarket in your area, but there are almost no fruits, vegetables, honey, milk, eggs, or chocolate. How would you feel Disappointed Angry Sad At this moment you realize people, plants, and animals are all connected. We need each other to live, and bees are one of the best examples of this connection.
Bees are very hard-working animals, and their greatest work is pollination. On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen with them. This action helps plants grow. In fact, without their work, about 80 percent of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planet.

Bees are also one of the most interesting animals in the world. For example, they work hard together to make their homes. In order to store honey, they create honeycombs. Another interesting thing about bees is how they communicate. When a bee finds new food, it uses a dance to tell the others where and how far away the food is.
Bees play an important part in the ecosystem of our planet. However, the number of bees is dropping, and scientists are worried. They need our help, and there is a lot we can do. Think about what you can do to protect one of the most amazing animals on earth.

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!
