What animal comes to your mind
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.
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 per cent 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.

There are many reasons for the dropping number of bees. First, pesticides are a big problem. When farmers use them on crops, bees might take in the harmful things while collecting pollen. Also, more and more natural habitats of bees are being destroyed. As people build houses, roads and factories, the fields and forests where bees live and find food are disappearing. Climate change is another reason. Unusual weather, like sudden cold or heat, makes it hard for bees to find enough flowers. These factors together are hurting the bee population badly.
Imagine you are the writer. Write one more paragraph about bees and add it to the text.
Bees are truly wonderful creatures. We can start by creating bee-friendly gardens. Plant flowers like sunflowers and lavender that bees love. Also, avoid using too many pesticides in our yards. Let's spread the world about how crucial bees are. By doing small things, we can help these little workers keep our world blooming and thriving.
How do you understand the connection between people, plants, and animals
A: We all know people and nature are connected. But can you give me an example of how they are connected
B: Sure. I visited a small town in Guangdong once. There are many large trees in the town. They are home to many birds. A lot of tourists come to see the trees and the birds …
The girl: We all know people and nature are connected. Can you show me an example
The boy: Sure! In my grandma’s village, there are fruit trees, like apple trees. Birds love to eat the insects on these trees. Without birds, insects would eat the tree leaves and fruits. Then, we can’t get delicious apples. So birds (animals) help fruit trees (plants), and we (humans) get good fruits to eat. We all need each other!
