We Can’t Live Without Bees
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.
Textbook

Read the text and underline the adjectives the writer uses to describe bees.
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.

3. Ants：Ants help plants grow by moving soil (like tiny farmers!). They also eat pests that hurt crops, so they protect our food.
Butterflies：They carry pollen between flowers, helping fruits/vegetables grow. Their beauty also makes parks/gardens nicer for us!
Textbook
1e
Imagine you are the writer. Write one more paragraph about bees and add it to the text.
Bees also have an amazing ability to remember the places of good flowers. They can find their way back to the best nectar sources, even after flying far away. This skill not only helps them survive but also ensures that more plants get pollinated. Without such smart little creatures, our world would be a much duller and less fruitful place. We should always remember to care for bees, for they care for our world in so many ways.
