Will books be replaced by the Internet?

Every morning, my father buys a newspaper on his way to work. Every day, I open my books in class and start my lessons. Every evening, my mother looks through magazines at home. And every night, I look at the photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or printing?

Paper was first created about 2, 000 years ago in China. After its invention, people started to write on paper to make books. In those days, books were only produced one at a time by hand. As a result, there were not many books, and they were expensive. So, few people had the chance to learn to read.

Printing was invented in China during the Sui and Tang Dynasties. Later, developments in printing made it possible to produce books more quickly and cheaply.
