In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .
A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .
Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 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 can also use cotton handkerchiefs (手帕) 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 .
Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .

Have you ever heard of a famous charity called Operation Smile? We hope we can help you understand how we are trying to help children all over the world.
Operation Smile was started by a doctor and his wife. In 1982, together with some volunteers, they went to Philippines to help children who had holes in their lips or inside their mouths. It was very difficult for them to eat and drink. These volunteers worked very hard. But they worried that they could not carry on with the work because they were short of money. Then they decided to start a charity so that they could help these needy children. They called it Operation Smile.
Operation Smile works in more than twenty developing countries and has cured over 10,000 children who have problems with their mouths. Operation Smile has won many prizes for its work and in 1999 they even started a special event called “The World Journey of Hope”. 5,000 children in 18 countries are cured during the event.
On the other hand, Operation Smile trains local doctors and nurses in developing countries so that they can continue to help children when Operation Smile has left. As to the children with much more serious problems, they will send them to America for further treatment.
So show your kindness and generosity to the needy children now. You can send your donation to Operation Smile at local banks. Many thanks from the children who can smile now will come to you.
