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
C.in more than one operation with slight mistakes
D.in one operation without any mistakes
61.Babbage failed to continue his research work in 1828 mainly because _______.
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
62.Babage explained his new idea to the government officials, expecting that _________.
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
63.From the passage, we can infer that __________.
A.Babbage failed to be a famous scientist at Cambridge
B.Babbage always had new ideas but gave them up easily
C.Babbage always needed support from the government officials
D.Babbage was the first designer of the modern computer

查看习题详情和答案>>Shakespeare, more perhaps than any other writer, made full use of the greatest resources of the English Language.Most of us use about five thousand words in our normal employment of English; Shakespeare in his works used about twenty-five thousand! There is probably no better way for a foreigner to appreciate the richness and variety of the English language than by studying the various ways in which Shakespeare uses it.Such a study is well worth the effort, even though some aspects of English usage, and the meaning of many words, have changed since Shakespeare’s day.
However, it is surprising that we should know comparatively little about the life of the greatest English author.We know that Shakespeare was born in 1564 in Stratford-on-Avon, and that he died there in 1616.He almost certainly attended the Grammar School in the town, but of this we cannot be sure.We know he was married there in 1582 to Anne Hathaway and that he had three children.We know that he spent much of his life in London writing his masterpieces.But this is almost all that we do know.
However, what is important about Shakespeare’s life is not its incidental details but its products, the plays and the poems.For many years scholars have been trying to add a few facts about Shakespeare’s life to the small number we already possess and for an equally long time critics have been theorizing about the plays.Sometimes, indeed, it seems that the poetry of Shakespeare will disappear under the great mass of comment that has been written upon it.
Fortunately this is not likely to happen.Shakespeare’s people have long delighted not just the English but lovers of literature everywhere, and will continue to do so after the scholars and critics and all their works have been forgotten.
1.This passage is about .
A. the great length of each chapter
