1970 was World Conservation (保护) Year. The UN wanted everyone to know that the world was in danger. They hoped something could be done.

    Here is one example of the problem. At one time there were about 1,300 kinds of plants, trees and flowers in Holland, but now only about 866 are left. The others have been destroyed by modern people and their science. We are polluting earth, air, water and everything around us. We can't live without these things. If things go on like this, we shall destroy ourselves.

    What will happen in the future? Perhaps it's more important to ask "What must we do?". More and more young people have known this. Many of them are helping to save our Earth. For example, they plant trees. In a small town in the United States, a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear about conversation through an album called "No One's Gonna Change Our World". It includes songs of Cliff Richard and other singers. The money from selling it will help to conserve tigers, elephants and pandas on Earth.

    GreenHome campaigners (发起者) really love the natural world. In fact, we love it so much that we're determined (决心) to do our best to protect it. {#blank#}1{#/blank#}For that, we need money too. GreenHome can be strong only with the support from people like you. {#blank#}2{#/blank#}

    If the joy of walking through the green forest, the excitement of climbing ancient rocks, or even the simple pleasure of watching wildlife in its own habitat (栖息地) really moves you, then share GreenHome's idea of the world. Please turn that idea into some support today.

    {#blank#}3{#/blank#}So take action right now! Even a very small amount, like$1a month, will soon build up into a valuable contribution (贡献) to protecting the natural world we love so much. {#blank#}4{#/blank#}We'll also use it to develop ways to deal with environmental problems.

    Think about it in another way. If you want a future where you can continue to do the things you love in the great outdoors, you need to make sure you've got great outdoors to do them in. {#blank#}5{#/blank#}And this way is simple enough—that's got to be worth $1 a month.

David was a truck driver. Recently he was thought to be a great man.

Last Monday, he was driving along the road with his son and his friend. Suddenly he saw a car hit another truck (卡车) and catch fire. The accident was just in front of his truck. Without thinking, he stopped his truck, found a fire extinguish er (灭火器) and ran towards the broken car. But other car drivers still sat in their cars. David began to fight the fire. His action encouraged his friend. He also came and gave David a hand. Later, David's son and four other men came to help. Another five men pulled the car driver and her granddaughter, a three-year-old girl, out of the car successfully. They were all safe except that the driver's leg was hurt.

When people talked about David's brave action, David said, " I didn't think too much then. I just did what other people would do in that situation. When I first got out of the truck,I wished they wouldn't be dead. When I saw they were alive, it was really great!"

Clouds change every second, bringing nature's{#blank#}1{#/blank#}to us But can you see it?

Cloud spotting, by its name, is just looking at clouds. Some people do cloud spotting to simply relax {#blank#}2{#/blank#}. Others do it to try and better understand clouds, from their {#blank#}3{#/blank#} to their names. Ji Yun, 36, is a cloud spotting expert in Beijing. 

In October 2013, Ji got a message from a friend, {#blank#}4{#/blank#}that some rare (稀有的) clouds were heading toward southeastern Beijing. Ji then bought tickets and went on a high-speed train to chase after them. 

"As soon as I got the information, I{#blank#}5{#/blank#}out of my home. After guessing where they were likely to head. I took a train to Tianjin. In the end, I {#blank#}6{#/blank#} in taking several wonderful pictures in the Wuqing district of Tianjin, "Ji said. The cloud took pictures of{#blank#}7{#/blank#}out to be one of the world's top 10 rarest clouds. 

This experience made Ji famous among the cloud spotters. He set up a WeChat group later that {#blank#}8{#/blank#}year to put people with similar hobbies together. They then set up chat groups in 2019 to cover different areas of China. Now, there are plenty of cloud spotting chat groups. Together, they became known as the Sky Enthusiasts Association(天空爱好者协会). Three years after the association was set up, cloud lovers collected every kind of cloud in the International Cloud Atlas. The International Cloud Atlas is a reference (查阅) book made by the World Meteorological （气象）Organization. 

"We created a book with all of these {#blank#}9{#/blank#} photos. And then we published （出版) it in late 2023, " Ji said. "This is a gift to all{#blank#}10{#/blank#}who love clouds. "
