小学生10分钟应用题系列答案In the 13th century, the famous 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 Cai Lun 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 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 give 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 then we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchief and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper, 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.

What do you think are the most important inventions of the past 2,000 years? The TV? The printing? The telephone? Or the computer? A report shows that these are not the only important inventions. Here are four other important ones.
Paper is one of the most important inventions. You can’t have printing without paper. In 105 AD, Cai Lun invented paper in China. Long before the printing and Internet, Cai Lun’s invention allowed us to write down information, stories and history.
One of the simplest (最简单) inventions to save life is the toilet. Before toilets, waste ran into the rivers from people’s houses. Illnesses were common (普通的) in big cities, and it was often difficult to find clean drinking water.
Animal food is another invention. Before the invention, most animals were killed every autumn because there was not enough food for them in the winter. After hay (干草) became a kind of common animal food, animals could live through the long winter.
Reading glasses is the fourth invention. People start getting far-sighted (远视) from the age of 45. Glasses mean that anyone can read, write and do “close work” after that age. Without glasses, the world would be difficult for the people above 45.

Tea bag drinking is most Westerners' favorite way of drinking tea. Do you know how it came about?
The tea bag was invented in 1908 by Thomas Sullivan, an American tea seller. He was sending out free tea in silk bags for people to try. People put the bags together with the tea leaves into the cup and added(增加) hot water. The tea tasted good, and people thought it was easy to clean the cup. They were not happy when Sullivan started sending them loose (散的) tea again.
Sullivan realized that he had a hot new thing in his hands, and he built a machine to pack the bags. As tea bags became popular, they were changed from silk to gauze (薄纱) and later paper. In 1952, Lipton Tea made the tea bag even more popular with its invention of the four-sided tea bag. Tea bags were soon a hit in the UK, and today 85%of the tea in the UK is packed in paper bags.
However, many people still prefer loose-leaf tea. This is because some tea companies put not very good tea in their tea bags. But for most drinkers, tea bags are still the easy and tasly way to go.
