created.

新课讲解
7
Write a passage about traditional printing and its future.
Use the sentences you have written in Activity 5 and 6 to help you.
新课讲解
Possible answer
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 year 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 book. As a result,
in the future, the Internet will probably be more important than printing.
