4. 磨表达 — 与原文保持风格统一
Possible Version:
There are lots of easy but helpful ways to protect bees. First, we can make our yards or balconies good places for bees. Planting flowers that have lots of sweet nectar—like lavender, sunflowers, and clover—is a great start. These flowers give bees nice food to eat. Also, don’t use harmful pesticides in your garden. Pesticides are like poison to bees. They make bees’ wings weak and stop them from finding their way back home. Another thing we can do is help local beekeepers. If we buy honey directly from them, we get pure, yummy honey. And it also encourages people to keep working as beekeepers. Every small thing we do adds up. It helps bees live and grow better.
1f
Think of some examples and then share them with a partner.
P37
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 …
有……栖息;是……的家乡
give sb.an example给某人举个例子
How do you understand the connection between people, plants, and animals Think of some examples and then share them with a partner.
A: Do you think people, plants, and animals are connected
B: Yes, I do! They need each other a lot. For example, plants make food with sunlight. Then animals like cows (牛) eat plants to grow.
A: Oh right! And people eat cows or plants for energy. That’s a good chain.
B: There’s another example. Bees (蜜蜂) drink nectar (花蜜) from flowers. They carry pollen (花粉) to help plants make seeds.
A: So plants can grow fruits and vegetables for us. And bees make honey (蜂蜜) that we eat too!
B: Exactly. If one part is hurt, others feel it. Like, no plants means hungry animals—and people won’t have enough food.
A: That’s true. We must protect all of them!
