How much paper do you use every year? Maybe you can’t answer this question quickly. In 1900 the world’s use of paper was about one kilogram for each person in a year. Now some countries use 50 kilograms of paper for each person in a year. But countries like America, England and Sweden certainly use more paper than other countries.

Paper was first made in China about 2000 years ago. It was made from the hair-like parts of certain plants. Paper was not made in southern Europe until about the year 1100. In 1500, a German named Schaeffer found out that one could make the best paper from trees. After that the forest countries of Canada, Sweden, America, Finland became the most important ones in paper making.

When we think of paper, we think of newspapers, books and writing paper. But there are many other uses. Only half of the paper is used for books and things like that. Paper is very good for keeping you warm. Houses are often insulated(使绝缘, 隔离 ) with paper. You may see some men asleep on a large number of newspapers. They’re insulating themselves from the cold. In Finland the temperature is sometimes -40 centigrade (C). The farmers wear paper boots in the snow. Nothing could be warmer.

Each year more and more things are made of paper. We have had paper cups and plates for a long time. But now we hear that chairs, tables and even beds can be made of paper. With paper boots and shoes, you can wear paper hats, paper dresses and paper raincoats. When you have used them away and buy new ones. People have made paper boats, but they haven’t made paper planes or cars. Just wait they perhaps will.
