A
If you and your friends wish to share a secret, you can write it in code, and no one else will be able to read it. Codes are one way of writing in secret. Ciphers (密码) are another. In a code each word is written as a secret code word or code number. In a cipher each letter is changed.
Codes and ciphers have played an important role in the history of the world. Julius Caesar, the Roman ruler who defeated almost all the countries in Europe about 2, 000 years ago, used a cipher when he sent secret messages to his troops. During the American Revolution, George Washington's spies used a kind of code to send him information about the enemy before his military action. In World War Ⅱ, the Americans "broke", or figured out, Japan's most important naval codes and got enough information to destroy a powerful Japanese fleet(舰队).
Storekeepers use codes to mark their goods. The codes show how much was paid for the goods or when they were added to the stock. Businessmen use codes to hide plans from their business enemies. Sometimes personal letters or diaries are written in code. Many people enjoy figuring out codes and ciphers simply as a hobby.
In the 16th century, codes and ciphers were very popular among scientists. They wrote messages to each other in code so that no one else would learn their secrets. Geronimo Gardano, an Italian astrologer(占星家), mathematician, and doctor, invented the trellis cipher. He took two sheets of paper and cut exactly the same holes in each one. Then he sent one sheet, which he called a trellis, to a friend and kept the other for himself. Whenever he wanted to write a message, he put his trellis over a clean sheet of paper and wrote the secret message through the holes. Then he removed the trellis and filled the rest of the paper with words that would make sense. When his friend received it, he put his trellis over the writing and read the secret message.
What does the underlined word "trellis"mean?
A. A piece of paper with many small holes. B. A machine with a lot of small holes.
C. A letter with unreadable words and sentences.
D. A sheet of paper with groups of Arabic figures.
Which of the following statements is true?
A. Ciphers can be broken or figured out more easily than codes.
B. You could read some words in Geronimo' s letter without his trellis.
C. The first person who ever used a cipher in history was Julius Caesar.
D. Fondness of using codes was the hobby of the scientists in the 16th century.
The best title of this passage is________.
A. Codes and Ciphers B. Differences between Codes and Ciphers
C. History of Codes and Ciphers D. Inventors of Codes and Ciphers

What is a good education? The question is far from being answered. Once more, colleges and universities are changing their programs: they drop "fun courses" and restart some of the traditional subjects neglected (忽视) since the 1960s. Many great schools are again requiring the students to take a number of classes in English, history, literature, the social sciences, philosophy, the natural sciences, and art if they want to get a degree. Meanwhile, the experts are trying to describe the good education of our time. Obviously the purely vocational training once favored is not enough. But neither is the gentleman's education of the nineteenth century. Educational programs must meet the demands of a modern world where men and women have to work and to deal with big problems.
What, then, is a good education of this century? Some educators suggest that it should include foreign languages and the study of foreign cultures; a mastery of English, including the ability to write and speak well, because communications have become all-important in the modern world, and also because "a person who doesn't speak and write clearly doesn't reason clearly either"; some knowledge of the social sciences (sociology, psychology) that deal with human relations and human problems; some basic knowledge of modern science, which would enable future voters to be better informed about current problems like nuclear. Finally, many educators insist that all college graduates should be familiar with computers and modern information system since the educated professionals of tomorrow will have to understand their machines. Is that all? "No, of course not." answer the educators. "We have not mentioned the two great building blocks of education: history and literature!"
