Paper was first created about 2,000 years ago, but books weren’t printed. They were produced by hand, so few people could read. Printing was invented during the Sui and Tang Dynasties. After printing developed, books were cheaper, so more people learnt toread. Today, the Internet is growing very fast, so that books might not be needed in the future. A much larger amount of information can be stored in more varied forms on the Internet than in books. As a result, in the future, the Internet will probably be more powerful than printing. The 82-year-old Sanlian Bookstore in Beijing officially started its around-the-clock operation on April 8th.A research released recently by the Chinese Academy of Press and Publication shows that every person in China read 4.77 printed books on average.
