What is the book made of？What we read books or newspapers，we hardly stop to think about the paper which is used to make them．Without this invention，our lives would be very different．
Paper is one of the most important inventions of all time．The word paper comes from the word papyrus-a grasslike plant．The Egyptians first used papyrus around the year 3000B．C．to make a kind of paper．In A．D.105，a Chinese man named Ts'aiLun created a new type of paper using pieces of old cloth．For centuries，people all over the world used this Chinese method（方式） to make paper．In 1838，Charles Fenerty，a Canadian man，invented a new method of papermaking using wood．Today，most of the paper we use is made from wood．
Think again about your book．Did you use paper money to buy it？If so，you can thank the Chinese．They invented paper money in the ninth century A．D．The government began using paper notes as money because there wasn't enough copper（鋼） to make coins．
Today，it's hard to imagine life without paper．We use it to communicate in many different ways．We also use many important products that are made of paper．Take for example，toilet paper．Many believe that an American．Joseph Gayetty，invented it in 1857．Walter Alcock，an Englishman，later had the idea to put the paper on rolls．By 1907，using toilet paper was common in the United States and England．
