纸是大约2000年前在中国被首次创造出来的。在它的发明之后，人们开始在纸上写字来制书。在那个年代，书是靠手工制作的，一次只能制作一本。因此，书籍又少，价格又贵。所以，很少有人有机会学者读书。
印刷术是在中国隋唐时期发明的 。后来，印刷术的发展使更快更便宜地制造书籍成为可能。书的交易形成了，更多的人学者读书，知识和思想比以前传播得更快了。在某种程度上，我们把纸和印刷术的发明与20世纪因特网的引入相媲美。
尽管因特网还在初期，但它发展很快，而且可能比印刷术变得更强大。在因特网上比在书籍中更大的信息量会以更多样化的形式被存储。使用网络连接的人比在印刷品中寻找信息的人能更容易地找到信息。我们用来阅读信息的机器现在又小又轻，经常比一本单独的书更小更轻。
现在电脑和因特网在教室中被使用,报纸和杂志已经能够在线阅读 。那么传统的印刷术未来的方向是什么？书籍将被因特网取代吗？让我们拭目以待。 Writing5P75Read the sentences and notice how we give reasons and results.Books were only produced one at a tie by hand. As a result, there were not many books.

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.重点短语
