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.

Many people think it is very exciting and admirable(令人羡慕的) to be an actor. The actors often wear the most beautiful and fashionable clothes and they can make a lot of money. Many people like them and they have so many fans. But in fact, the job of an actor can be very tiring and hard. To make good movies, for example, action movies, the actors need to go to some remote(偏远的) places. There they don't have good places to stay or nice food to eat. They often have to get up early and go to bed very late. When they are too busy, they don’t have time to sleep or relax. It's very hard.
