stay in China, he discovered that the Chinese used paper money. In western countries, people did not use
paper money until the 15th century.
A Chinese man called Cai Lun invented paper almost 2000 years ago. He made it from wood.
Now paper still comes from trees. We use a lot of paper every day. Every day, people throw away
about 280 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are
cutting nearly 4800 trees every day. Since it takes more than 10 years for a tree to grow, we must start
using less paper now. If we don't, we will not have enough time to grow more trees to take the place of
those we use for paper.
So how can we save paper? We can use both sides of every piece of paper, especially when we are
making notes. We can choose drinks in bottles instead of those in paper packets. We also use cotton
handkerchiefs and not paper ones. When we go shopping, we can use fewer paper bags. If the shop
assistant does give us a paper bag, we can save it and reuse it later.

High in the mountains, and deep in the forest, lives a lake with many plants and animals in and around her. The plants and animals have enough food and clean water to keep them healthy. The wind carries pure air, and the rain comes down clear and clean.
But recently, Lucy Lake and her friends haven’t been feeling very well. All the plants and animals get together to talk about the problem. “Why are we sick?” “What can we do?” ask all of them. No one has any answers.
Just then two hikers appear. The animals tell them about their problems. “Can you help us?” they ask. “Yes,” one hiker says. “I think it’s because of acid rain.”
“Acid rain comes from chemicals(化学物质) in the air. The pollution comes from factories, cars and trucks.”
“So, although I don’t want to, I help the pollution travel through the air!” says the wind. “And I carry it to the land!” cries the rain.
“If you can help us think of some solutions(解决方法), we will send a message to tell people how to clean up our environment,” one hiker says.
With the help of the plants and animals, the two hikers make a list of ideas for saving Lucy Lake and her friends.
Time passes, and the forest and lake begin to feel a little better.
The next time the hikers climb up the mountains to Lucy Lake, they smile at what they find. “We’re glad things have started to change,” one hiker says. “And we’re glad you helped us make a difference,” says the other.
