In the 13th century(世纪), the famous Italian traveller, Marco Polo, travelled 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(然而), people in China began to use paper money in the 7th century．
A Chinese man called Cal 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(吨)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 choose drinks in bottles instead of those in paper packets(袋)．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(店员)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 writer tells us to ________ while we are making notes．
From the time we were babies we have been taught manners．We are taught how to hold a knife and fork and not to talk with our mouths full．We are taught how to shake hands and when to stand and when to sit and the way to introduce people．
Sometimes good manners in one place are very bad manners somewhere else．Almost everywhere eating together means that people are very friendly to each other．But in parts of Polynesia(波利尼西亚)it is bad manners to be seen eating beside each other．So they politely turn their backs to each other when they are taking food．
Some East Africans spit four times as a kind of blessing(祝福)．They do it to show that they want a sick person to get well, or to bless a new-born baby．In most other places, spitting means something completely different．It usually shows an unhealthy habit．In many countries, it may mean that you hate someone．
When we go to visit someone we say “ Hello!” Or “ How are you?” or things like that．
But if you are visiting an East African village, everyone will be very careful not to pay attention to you, The polite thing there will be for you to go quietly, without speaking to anyone, and sit beside your friend．You should wait until he has finished what he is doing and then he will begin talking to you．
In a village in Arab, a visitor will walk behind all the tents until he gets to the one he wants to visit．If he passes in front, he will be invited into each tent and asked to eat．It is rude to refuse．
