We Can’t Live Without Bees没有蜜蜂我们无法生存
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.蜜蜂是很勤劳的动物，他们最伟大的工作是授粉。在一次行程中，它们常常会造访50到100朵花。当它们从一朵花飞到另一朵花上时，它们携带花粉。这种行为有助于植物成长。事实上，如果没有蜜蜂的工作，世界上大约80%的植物无法生长。出于这个原因，许多科学家认为蜜蜂是这个星球上最重要的动物。

3. What do you know about the connection between humans and other insects, such as ants and butterflies 你对人类和其他昆虫，比如蚂蚁和蝴蝶之间的联系有什么了解？
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.

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.

1f
例子：A: We all know people, plants, and animals are deeply connected. Can you share a more detailed example of this connection 我们都知道人类、植物和动物之间有着深刻的联系。你能分享一个更详细的例子来说明这种联系吗？
B: Sure. Last summer, I visited a small village in Zhejiang. The village is surrounded by lush bamboo forests, which are home to hundreds of wild birds and small animals like squirrels. The villagers have lived in harmony with this ecosystem for generations: they don’t overcut the bamboo, and they set up birdhouses to protect the local wildlife. In return, the bamboo provides them with materials for crafts and building, while the birds control pests in the rice fields, helping to ensure a good harvest. Now, the beautiful bamboo forests and the lively wildlife have also become a popular eco-tourism spot, bringing more income to the villagers and encouraging them to protect the environment even more.当然。去年夏天，我去了浙江的一个小村庄。村子被茂密的竹林环绕，这里是数百种野生鸟类和松鼠等小动物的家园。村民们世世代代与这个生态系统和谐共处：他们不过度砍伐竹子，还搭建鸟屋来保护当地的野生动物。作为回报，竹子为他们提供了制作手工艺品和建筑的材料，而鸟类则控制了稻田里的害虫，帮助确保了丰收。现在，美丽的竹林和生机勃勃的野生动物也成了热门的生态旅游景点，为村民带来了更多收入，也激励他们更加积极地保护环境。
