I can see an empty street with no people or cars on it.The whole street is quiet . There are multi‑story brick buildings, closed‑down shops. 5 What does “stands still” mean? It means “stop” or “pause”, just like the symbol in the picture. Pre-reading Activity 1 6 What do you think the passage is about? The passage is about a world without humans.

Think and share. 2 What changes can you make to “permit nature to have her way”? I can make small changes in daily life, such as saving water, planting trees, using less plastic and protecting animals. In this way, I can help protect nature and make the environment better for plants and animals. Work in groups In the last paragraph, the writer says, “The rapid development of human society has made us care less for nature.” So, do we have to stop human development to protect nature? No, we don’t have to stop human development. We need a better way to develop. For example, We can use green energy instead of coal. We can build clean factories and set up more national parks to protect animals. We must develop carefully, think about the earth’s future and keep a fine balance with nature.
