Johann Gutenberg, who worked as a goldsmith(金匠)，took what has already been discovered, and created a small invention that changed history. He created a machine that allowed him to move small blocks of letters in such a way that written material could be printed and mass-produced. Few people could read before Johann Gutenberg made the invention, but once books became less expensive, more Europeans could read and write.
Block printing existed long before Gutenberg. The Chinese had been using wood blocks to print books as early as 868, but a new set of woodcuts(木刻印版) had to be made for each book. Producing one book was not easy; producing all kinds of books was more difficult.
Writing ink dates from about 2500 BC in Egypt and China. Johann Gutenberg use an oil-base printing ink that would last longer than other inks used in his time. We don’t know much about Gutenberg because he was not famous during his lifetime. He was born in Germany about 1400. In 1448, Gutenberg developed signatures for each number, letter, and punctuation mark(标点符号). He then built the molds (模型) to hold the signatures in place. Johann Gutenberg published the first mass-produced book: a 1,282 page Bible. To this day, more copies of the Bible have been printed the any other book.
Copies of Gutenberg’s invention spread throughout Europe, but the German goldsmith did not get rich from his invention. Some officials denounced the invention of printing because they feared that it would spread bad ideas. By 1500 there 1,700 printing presses in Europe. The presses had already produced about 20 million volumes of 40,000 different books.

(答案→)A 解析：通读全文可知是关于改变世界的一项发明—印刷术。【小题1】A 细节题。根据第一段最后一句Few people could read before Johann Gutenberg made the invention, but once books became less expensive, more Europeans could read and write.可知A正确。【小题2】C 细节题。根据第三段Writing ink dates from about 2500 BC in Egypt and China. Johann Gutenberg use an oil-base printing ink that would last longer than other inks used in his time.可知他使用的墨水很不一样，能持续时间更长。【小题3】A 猜测词义题。根据后半句because they feared that it would spread bad ideas.可知他们对于这样的技术是持反对态度的，认为它会传播坏的思想。故A正确。【小题4】C 主旨大意题。通读全文可知是关于改变世界的一项发明—印刷术。
