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（運算）.

    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.

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