Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.

“Dad will be really mad if he finds out you’ve been playing with his new computer” Jason said, “He told us not to touch it.”

“He won’t find out,” Mark said, “I’ll just have a quick look and shut it down.”

Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.

It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”

“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead!” A new message appeared on the screen:

“ENTER NAMES

VOYAGE�。�

VOYAGE�。�

Mark’s finger flew across the keyboard as he typed in both of their names.

“INPUT ACCEPTED.

START  TRANSPORT  PROGRAM.

AUTO-RETRIEVE  INITIATED(自動(dòng)回收程序已啟動(dòng)).”

The screen turn even brighter and a noise suddenly rose in volume.

“I think we’d better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒)，until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed：

“TRANSPORT SUCCESSFUL．

DESTINATION:  MARS.

RETRIEVE DATE:  2025

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(標(biāo)點(diǎn)符號(hào)). 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.

1.What happened after Johann Gutenberg’s invention?

A．People could afford to read books.

B．People became interested in inventing.

C．It was still difficult to print all kinds of books.

D．Punctuation mark began to be used in printing.

2.Compared with block printing in China, Johann Gutenberg’s method __________.

A．was difficult to run.

B．needed harder paper

C．used a new kind of ink

D．was put into use earlier

3.The underlined word “denounced” in the paragraph means __________.

A．fought against

科目：高中英語(yǔ) 來(lái)源：2013屆浙江省高二下學(xué)期期末考試英語(yǔ)試卷（解析版） 題型：閱讀理解

A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds.

The machine squirts (噴射) out chocolate and, via computer instructions, allows the user to build any shape they like out of the food. But makers Choc Edge have missed the Easter rush. Even so, they hope the printer will be snapped up by retailers (零售商) immediately they come to the market. Britain’s biggest chocolatiers Thornton’s have already said they are interested. Because of the high cost, however, few individuals are likely to buy one. But the devicecould one day allow people to design their own 3D objects after submitting their designs on a website. Dr Hao, founder of Choc Edge came up with a prototype (原型) last year and has only just perfected it so that it can now go on sale. “We’ve improved and simplified the machine, so now it is really easy to use,” he told the BBC. “You just need to melt some chocolate, fill a syringe (注射器) that is stored in the printer, and get creative printing of your chocolate.”     

3D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products, but this is the first time the principles have been applied to chocolate. The research has presented many challenges. Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. Dr Hao said, “What makes this technology special is that users will be able to design and make their own products. From reproducing the shape of a child’s favourite toy to a friend’s face, the possibilities are endless. It could be developed to help consumers design many products from different materials, but we’ve started with chocolate as it is easily available, low cost and harmless.” “There is also no wastage as any spoilage (損壞物) can be eaten.” Dr Hao added, “Eventually we may see many mass-produced products replaced by unique designs created by the customer.”[來(lái)源:]

EPSRC chief executive Professor Dave Delpy said, “This is a good example of how creative research can be applied to create new manufacturing and retail ideas. By combining developments in engineering with the commercial potential of the digital economy，We can see the new market prospect (前景)—creating new jobs and, in this case, the chocolate printer is called sweet business opportunities.”

1.Which is the advantage of the chocolate printer?

A．It is easilyavailable, low cost and harmless.

B．It mainly produces children’s favourite toys.

C．The user can build the shape they like via computer instructions.

D．The designs made by it are the same as many mass-produced products.

2.What can we conclude from the passage?

A．The printer sold well during last Easter.

B．The technology of 3D printing promises a good future.

C．The printer was perfected and went on sale many years ago.

D．It’s the first time that the technology has been used in industry.

3.Dave Delpy’s attitude towards the chocolate printer is __________.

A．doubtful

B．supportive

C．negative

D．critical

4.We can conclude that this passage is a __________.

A．science fiction

B．book review

C．news report
