听力原文： Paper is one of the most important products ever invented by man. Widespread use of written language would not have been possible without some cheap and practical material to write on. The invention of paper meant that more people could be educated because more books could be printed and distributed. Together with the printing press, paper provided an extremely important way to communicate knowledge.

How much paper do you use every year？ Probably you cannot answer that question quickly. In 1900 the world's use of paper was about one kilogram for each person a year. Now some countries use as much as 50 kilograms of paper for each person a year. Countries like the United States, England and Sweden use more paper than other countries.

Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before the year 1400. The Egyptians wrote on a kind of material made of a water plant. Europeans used parchment for many hundreds of years. Parch-ment was very strong; it was made from the skin of certain young animals. We have learnt of the most important facts of European history from records that were kept on parchment.
