E-books
What are they
which one would you prefer, reading books on screen or on paper And why
Discussion
Will paper books be replaced by e-books
I think that paper books are better because I love the feel of a real book in my hands.
I prefer to read an e-book because it takes up less space and it's a lot lighter than a paper book.
for example
E-books are cheap and they are convenient for you to carry everywhere.
E-books allow individuals to acquire any book they would like at any time.
E-books lack soul.
people will always need the value, the real and the tangible(有形的).
Paper books can be taken anywhere, and do not rely on power.
Paper-books don‘t normally cause significant eye-strain(视疲劳).
E-books are much more environmentally friendly.
With the rapid development of the internet, will paper books be really replaced by e-books Let’s wait and see.

P75
Write a passage about traditional printing and its future. Use the sentences you have written in Activities 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.
