Today, the Internet is growing very fast.
Computers and the Internet are used in
classroom now, and newspapers and
magazines are read online.
Write a passage about traditional printing and its future.
Use the sentences you have written in Activity 5 and 6 to help you.
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.
