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!"

If your recurring(经常性的)dreams are worrying you，you can rest assured and needn’t worry.Psychologists say in the vast majority of these cases，this is just the mind’s way of dealing with stress and conflicts，problems and concerns.It’s a good thing.
They call be surprisingly vivid and real，or fragmented and weird.They can be comforting or frightening.Our dreams can tell us a lot about what we are really thinking.Dreams give us an x-ray of our unconsciousness(潜意识).They tell us，particularly when we are at life’s passages or turning points.
Lisa Oppenheim had the same dream whenever she was about to move to a new home or a new city.It’s always just a feeling of needing to stay safe.Experts say disturbing dreams often occur around major life events.For Lisa，it was moving.For others，it can be marriage or divorce，the death of a loved one or pressure at work.
Doctor Siegel has studied the meaning of dream for nearly 30 years.He believes stressful or upsetting dreams can be a sign of what’s buried deep inside our minds.
He said.“Dreams are important to survival.They are crucial to the balance of our psyche(心灵).They help us work out problems that we’re having every single day.They go to the cutting edge of what’s stressful，what’s bothering us and what we’re working out in our lives.Dreams can guide us and in order to find that guidance，to find that deep source of wisdom that’s in our dreams every night，we need to pay attention to our dreams.”
But many dreams are scary and horrible.How can we understand these nightmares? Doctor Siegel says they are reflecting especially intense emotion or unresolved conflict.The stronger the emotion in the dream，whether it’s pleasure or fear，the likelier the dream is to be important.
Knowing what your recurring dreams or nightmares mean can be liberating.Some nightmares can be a sign of serious psychological problems，such as post-dramatic stress disorder.If they are extremely disturbing or violent or the cause of severe anxiety，you should see a professional therapist(治疗专家).

What is freedom? It seems like such a simple question. Freedom is being able to do what you want to do. Allow me to explain it.
I’m tired of working for a living. I’d rather collect taxes. So that’s what I’m going to do: collect a kind of tax. You are ordered to estimate your income from the past 12 months, and write me a check for 1%. I have provided a mailing address for this purpose on my contact page …
What? You have a problem with my plan? Oh, I see. If you have to send me a check for the tax, then I have hurt your freedom to spend that money as you see fit. We have a conflict! And our basic problem is: we cannot enjoy freedom at the same time; we must settle for a limit. But what limit?
Libertarians (自由论者) believe freedom should be based on self-control. They describe freedom as being able to do what you want to do as long as it doesn’t influence the equal right of others to do what they want to do. That is, freedom is being able to do what you like as long as you do not harm another person’s life, liberty or property.
You can build a set of legal and ethical (道德的) rules on the principle of self-control, and libertarians do. Their request for self-control often becomes more important than common sense, or even freedom itself.
The definition rules out the freedom to steal, murder, and so on. Otherwise, you can do whatever you want. There is no problem until you realize that taxation is theft, that war is murder, and that national service is a form of slavery. Since only the government has a legal right to use force, libertarians focus on making the government smaller, or even going without it. The libertarians’ definition of freedom is thus freedom from the government. Isn’t it ridiculous?
