Pre-reading
The text is probably about how bees connect plants, animals and humans, and why bees are so important for our lives.
Skimming
Task 1: Match the main idea with each paragraph.
Bees are in danger.
People are connected to bees.
Para 2
Para 3
Bees are hard-working and the most important animals in this planet.
Para 1
Para 4
Bees are one of the most interesting animals in the world.
Task 2: Find the adjectives for bees.
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.

Para 2: Bees are hard-working and the most important animals in this planet.
There is pollen on the bee’s body.
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.

Imagine you are the writer. Write one more paragraph about bees and add it to the text.
Habitat loss （栖息地丧失）
Pesticide exposure （农药暴露）
Climate change （气候变化）
Reason: cities expand; forest disappear; bees lose flower homes; …
Reason: farmers use chemicals; poisons make bees sick; …
Reason: warmer weather; flower bloom wrong; poisons make bees sick; …
Sadly, bees face serious dangers that affect our ecosystem. Habitat loss is a big issue. As cities expand and forests disappear, bees lose places with flowers to live. Pesticide exposure also harms them. Farmers use chemicals on crops, and these poisons make bees sick, stopping them from finding food. Climate change is another problem. Warmer weather makes flowers bloom at wrong times, so bees can’t get nectar when needed. These threats show why we must protect bees — by saving their habitats, cutting pesticide use and fighting climate change.
