　The boys sadly 　3　their exercise books and began to write the numbers down—all of them 　4　one boy, who had been in that school only for a few days． This boy looked out of the window for a few moments, wrote a number in his exercise book and 　5　his hand．

　“May I go home when I've found the answer, sir? ” he asked．

　“Yes, you may, ” answered the teacher．

　“Well, I've found it, sir” said the boy．

　The teacher and the other boys were all very surprised．

　“　 6　,” said the teacher．

　The boy brought it． It was quite correct, so the teacher had to let the boy go home． The next morning, the 　7　teacher asked the new boy how he had found the answer so quickly．

　　　“Well, sir, ” he said, “I thought that there 　8　the answer, and I found one, you see, If you add 100 to 1, you get 101, and if you add 99 to 2, you also get 101, 98 to 3 is 101 too, and if you go on until you reach 51 and 50, you have 101 fifty times, which is 5050． ”

　After this, the teacher gave the boy 　9　the other boys in the class． His name was Karl Friedrich Gauss, and when he 　10　, he became a famous professor of mathematics．

　　　When he left university, he started a factory with his brother to make a new and very powerful explosive． At first the factory 　13　, but one day there was a terrible explosion (爆炸) in the factory． It killed several workmen and Alfred's brother． Alfred himself was not there that day．

　　　Alfred 　14　after his brother's death, but he did not stop working; he moved his factory onto a boat, and took it a few miles out to sea． “If 　15　,” he said to himself, “I will be killed, but 　16　will be hurt． ” He was not killed 　17　, but made a new and much safer explosive． He called it dynamite (甘油炸藥)．

　This was the time, in 　18　of the nineteenth century, when many modern roads and the first railways and tunnels 　19　in Europe． Everybody wanted to use Nobel's new dynamite． He soon became very rich．

　　　But Nobel's dynamite was not always used for making roads; it was also 　20　making war． “It's Nobel's fault (錯(cuò)誤), ” many people said, “It's his dynamite they're using to make war． ” It was true; it was his dynamite; but was it his fault?

　One day, in 1891, Nobel opened a newspaper and read the story of his own death! It was 　21　, of course, and at first he laughed; but he did not laugh then he saw the things the newspaper 　22　him, “A very bad man, ” they said, “…terrible…wanted to destroy the world with his dynamite…”

　　　In 1896, Alfred Nobel died． But that was 　24　his name． When he died, he left a lot of 　25　five Nobel Prizes． These are given every year for important work in five different fields, One prize is for chemistry, another for physics and another for medicine; there is also one for literature (文學(xué)); and the fifth one, the most important one for Alfred Nobel, is the Nobel Peace Prize．
