Ⅳ.阅读理解
Every morning my father buys a newspaper on his way to work. Every evening my mot looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or print?
Paper was first created about 2,000 years ago, and was made from silk, cotton, bamboo and since the 19th century from wood. People learned to write words on paper to make a book. But it those days, only one book could be produced at a time by hand. As a result, they were expensive and rare. And because there weren’t many books, few people learned to read.
Then printing was invented in China. When printing was developed greatly at the beginning the 11th century, books could be produced quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly.
Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD ROMs or machines such as MP3 players.
Computers are already used in classroom, and newspapers and magazines can already be read online. So will books be replaced by computers one day? No, I don’t think the Yao Ming poster on my bedroom wall will be replaced by a two-metre-high computer!
21. When was paper first created?
A. About 2, 000 years ago. B. In the 19th century.
C. About 1, 000 years ago. D. In the 11th century.
22. Why were books expensive and rare before the invention of printing?
A. Because people could not read.
B. Because people could not write words on paper.
C. Because people could not find silk, cotton or bamboo.
D. Because people could only produce one book at a time by hand.
23. What happened after books became cheaper?
A. People didn't want to buy books.
B. Printing was invented in China.
C. Knowledge and ideas spread quickly.
D. The Internet was introduced to people soon.
24. What is the writer’s opinion about books and computers?
A. People won't need books any more.
