P75
Write a passage about traditional printing and its future. Use the sentences you have written in Activity 5 and 6 to help you.
It’s hard to imagine a world without printing because we have so many printed things now, for example, menus, comics and schoolbooks. Paper was first created about 2,000 years ago, but books weren’t printed at that time. They were written by hand, so few books were produced, and, as a result, few people could read.
Printing was invented during the Sui and Tang Dynasties. After printing developed, books became cheaper, so more people learnt how to read. Today, the Internet is growing very fast. 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 important than printing.
