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.
在13世纪,著名的意大利旅行家马可波罗,长途跋涉来到中国.他在中国逗留的时候,看见了许多奇妙的事物,其中之一就是他发现中国是使用纸币（银票）的.在西方国家,人们直到15世纪才开始使用纸币.然而,中国人在7世纪便已开始使用纸币了.
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.
一个叫蔡伦的中国人在2000年前发明了造纸术.凭借从树木中取得木材作为原料,他制造出了纸.然后,他将多张纸钉在一起,便成了书本.
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.
如今,纸张的原料依然是木材.每天,我们都消耗大量的纸张.如果我们持续浪费,那么这个地球上的森林将会所剩无几.而假如没有树木,就没有纸.每天,人类都要扔掉大概2800吨的纸,而每17棵树才能制造1吨纸,这就意味着每天要砍伐48000棵树.而每棵树要用超过10年才能栽培好,所以我们必须从现在开始少使用纸张了；否则,人类便没有足够的时间去栽培更多的树木,来抵消我们每日使用掉的纸.
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.
那么我们该怎么节约用纸呢?我们可以两面使用纸张,特别是我们做笔记的时候；我们可以用瓶子饮水,而不是用纸杯；我们还可以使用棉手帕,而不是用纸巾.去购物时,我们也可以少用纸袋.假如店员真的要给我们用纸袋,我们可以存着,以便再次使用.
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.
每个人都能节约用纸.如果我们都能考虑谨慎些,我们便可以帮助保护森林.但我们应该从现在做起,趁现在还为时未晚.
打得好长啊,望采纳,希望你满意!谢谢~
