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 (噸) 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 .

The basketball final between Perfect School and Sunrise School has entered white-hot stage. There are only fifteen seconds left. Sunrise School is one point ahead. Mitchell, who is one of the best players of Perfect School, is now controlling the ball. The students are extremely excited. They cannot help standing up and shouting, “Go! Mitchell!”O(jiān)ther teammates also encourage Mitchell, “Take a shot, boy!”
Mitchell knows it will be the last shot. He hesitates (猶豫) and falls into careful thinking. He imagines that he shoots from the halfway line. The hall turns quiet. All eyes follow the track of the basketball. It jumps round the ring over and over again and finally rolls out of the court. The world turns noisy. Mitchell sees his coach lower his head, his teammates kneel down and his fans cry. It gives him so much pain. It is the last match for his coach before retiring. All the teammates practiced hard and hoped to give their coach a perfect ending. But now, the bubble bursts (破裂).
“Is that what you want?” Mitchell asks himself.“Certainly not. But how can I change the situation? Teamwork!”Mitchell returns to reality from his thinking. He does not have a shot by himself but surprisingly passes the basketball to his teammate, Jack, who is standing near the basket. Jack catches the basketball and quickly scores a two-point shot. There goes the whistle at the same time. Perfect School finally wins the game.

Do you like traveling? How can you make your trip interesting? Here’s some advice.
Read!
Before you leave, you should find some information about the place, such as its geography, history and people. You can introduce that place better by reading.
Take photos!
If you want to take some photos, remember to choose the most special sights. Don’t choose the sight you can see in other places. For example, Qingdao and Ningbo are coastal cities, so don’t only take photos of the sea. You should take photos of something else, too.
Taste!
You’d better taste some specials(特產(chǎn)) in the area. Food in some places is very delicious. So why not taste it? Maybe you have just one chance to taste it in your life.
Write!
When you visit a place, you should take a pen and a notebook, so you can write down what you see and what you think during the trip.
