B文化自信·中国四大发明之一——印刷术)
Printing was invented many years ago.And woodblock printing, known as the “living fossil (化石)” in the printing history, still has its traditional charm today.
During the Tang Dynasty (618－907), Buddhism (佛教) became very popular in China. There was a strong need to produce a large number of Buddhist scriptures (经文), and copying by hand could not meet the rising demand．Therefore, ancient Chinese craftsmen (工匠) came up with a new way to make lots of copies—woodblock printing.In the Song Dynasty (960－1279), woodblock printed books were quite popular.
Traditional woodblock printing can be divided into four main steps: writing, carving (雕刻), printing, and binding (装订)．Each of these steps includes many smaller tasks, and in total, about 30 steps are needed to create a woodblock print.
Carving is at the heart of woodblock printing because this step can make or break the final print.Skilled craftsmen carve characters and pictures to create raised areas or lines.They will hold ink for printing.
One famous example of woodblock printing is The Diamond Sutra (《金刚经》)．It's considered the “earliest dated printed book” and is stored in the British Library.This ancient art form not only shows the wisdom of Chinese people but also the beauty of Chinese craftsmanship over the centuries.
Before printing, writing allowed people to share their thoughts.But it was the invention of printing that made knowledge a shareable fruit for humankind.
26. (　)When was woodblock printing first created
A．Two thousand years ago.
B．In the Song Dynasty.
C．Three thousand years ago.
D．In the Tang Dynasty.
27. (　)(中考趋势题) What does the underlined word “demand” in Paragraph 2 mean
A．Standard. B．Conditions.
C．Charm. D．Need.
28. (　)Which English saying can explain the importance of carving
A．No pain, no gain.
B．A miss is as good as a mile.
C．Burn the candle at both ends.
D．Many hands make light work.
29. (　)(高阶思维·推理判断) What is the main purpose of the passage
A．To compare different types of printing.
B．To recommend a woodblock printed book.
C．To introduce a kind of traditional Chinese printing.
D．To explain the importance of ancient craftsmen.
30. (　)How is the passage organized
A．By comparing different printing methods.
B．By listing the steps of woodblock printing in detail.
C．By following the order of time and importance.
D．By analyzing the causes and effects of printing.
