When Babbage was working at Cambridge, a new idea occurred to him. He wanted to construct a calculating machine to work out the solutions（解法）to maths problems not only with correctness but also with a speed beyond the power of any human mind. His machine could solve problems involving（涉及）long rows of figures in one continuous operation（运算）.

       In 1822 Babbage exhibited his invention and won a prize from the government. After that, he immediately started to work on a larger machine designed to solve more difficult problems. Although he received some money left by his father, the money was not enough to support his design. He wrote to the government about his plan and was given ￡2500 to start with, a sum worth much more in those days than it is now.

       Babbage continued his work in London for four years. Then his health broke down, and he had to take a long holiday abroad. When he returned to London in 1828, he was at the end of his resources. Many bills remained unpaid. His chief assistant and co-workers quarreled with him and left with many expensive tools. For one year no work was done. During this period, Babbage, whose mind was always active, suddenly thought of a completely new idea for the machine. He rushed to meet the government officials to explain his new idea. But this time, they were unwilling to help him. For eight years, they refused to say whether they wanted the machine or not, and their final answer was “No.”

       From 1828 to 1839, Babbage held the position of professor at Cambridge very successfully. But his greatest work was the unfinished calculating machine which stood covered in dust in his house. It was the beginning of the modern computer.

60．The machine Babbage designed would solve difficult maths problems _________.

      A．in one operation with few mistakes

       B．in more than one operation without any mistakes

      A．he was in poor health    B．he almost ran out of money

       C．his co-workers argued with him         D．he spent all his money on his bills

      A．they would agree to his plan    B．they would pay for his new idea

       C．they would support him with money   D．they would exhibit his new design

       C．Babbage always needed support from the government officials

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 (喷射) 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 (损坏物) can be eaten.” Dr Hao added, “Eventually we may see many mass-produced products replaced by unique designs created by the customer.”[来源:]

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.”
