“A friend walks in when the rest of the world walks out.” Sometimes in life, you find a special friend: someone who changes you life just by being part of it; someone who makes you laugh until you can’t stop; someone who convinces( 使相信 ) you that there really is an open door just waiting for you to open it. This is forever friendship.

When you're sad, and the world seems dark and empty, your forever friend lifts you up in spirits and makes that dark and empty world suddenly seem bright and full; Your forever friend gets you through the hard times, the sad times, and the confused times.If you turn and walk away, your forever friend follows; If you lose your way, your forever friend guides you and cheers you on; Your forever friend holds your hand and tells you that everything is going to be ok.

And if you find such a friend, you feel happy because you need not worry. You have a forever friend for life and forever has no end.

In the 13^th century, the famous Indian traveller, Marco Polo, travelled a long way to China. He saw many wonderful things. One of the things he discovered was that Chinese used paper money. In western countries, people did not use paper money until the 15^th century. However, people in China began to use paper money in the 7^th century.

    A Chinese man called Cai Lun invented paper almost 2,000 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 left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 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 also use cotton handkerchiefs（手帕） and 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 refuse（拒绝）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.
