However, the number of bees is dropping, and scientists are worried. Bees 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. We Can’t Live Without Bees 1b Read the text and underline the adjectives the writer uses to describe bees. Can you think of more adjectives to describe bees?

Post-reading 861b240d-cd4e-4b4b-87c2-161e8c2fa4ea.source.default.zh-Hans 17 Bees have five eyes. They have two large compound eyes on the sides of their head and three small simple eyes (ocelli) on the top of their head, which help them detect light and navigate. Different types of bees have different lifespans. For example, worker bees usually live for a few weeks during the busy summer months, while the queen bee can live for several years. Bees can recognize human faces. They use their visual and olfactory senses to distinguish different human features. Post-reading 2. What other interesting facts do you know about bees? Food source: Ants can be both beneficial and harmful to humans. Some ants help control pests in gardens by preying on small insects, which indirectly benefits human agriculture and horticulture. On the other hand, some ants can damage crops or invade homes in search of food, causing inconvenience to humans. Ecosystem balance: They play a role in soil aeration as they dig tunnels, which helps improve soil structure and allows plant roots to grow better. This is beneficial for human-related plant cultivation. Post-reading 3. What do you know about the connection between humans and other insects, such as ants and butterflies? Pollination: Like bees, butterflies are important pollinators. They transfer pollen from one flower to another while feeding on nectar, which helps plants reproduce. This is crucial for the growth of many plants that humans rely on for food, medicine, and ornamental purposes. Indicator species: Their presence or absence can indicate the health of an ecosystem. A decline in butterfly populations may signal environmental problems such as pollution or habitat loss, which also ultimately affects human-living environments. 3.

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 are the writer. Write one more paragraph about bees and add it to the text. There are many ways we can do. First, we can plant bee-friendly flowers and plants in our gardens or balconies. These provide bees with nectar and pollen. Second, avoid using pesticides as they can harm bees. Instead, try natural pest-control methods. Finally, spread the word! Let more people know the importance of bees and encourage them to join in protection efforts. 1e How do you understand the connection between plants, animals, and people?
