From the beginning of human history, wild animals provided food, clothing and sometimes medicine. We may not depend so much on wild animals now. But we hear about them every day. Americans use the names of animals in many ways. Automobile manufacturers (制造商) and gasoline companies especially like to use big cats to sell their products. They like lions, tigers and wildcats. When Americans say wildcat, they usually mean a lynx, an ocelot or a bobcat. All these cats attack quickly and fiercely. So wildcats represent something fast and fierce.
An early American use of the word wildcat was quite different. It was used to describe members of Congress who declared war on Britain in 1812. A magazine of that year said the wildcat congressmen went home. It said they were unable to face the responsibility of having involved their country in an unnecessary war.
Wildcat also has been used as a name for money. At that time, some states permitted banks to make their own money. One bank in the state of Michigan offered paper money with a picture of a wildcat on it. Some banks, however, did not have enough gold to support all the paper money they offered. So the money had little or no value. It was called a wildcat bill or a wildcat bank note.
The banks which offered this money were called wildcat banks. A newspaper of the time said those were the days of wildcat money. It said a man might be rich in the morning and poor by night.
Wildcat then was used for an oil well or gold mine that had almost no oil or gold in it. Dishonest developers would buy such property. Then they would sell it and leave town with the money. The buyers were left with worthless holes in the ground. Today, wildcat oil wells are in areas that are not known to have oil.
【小题1】What is the main idea of the passage?

No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus, on doing one specific job.
Let’s take a man we’ll call Mr. Fielder, for example. He did everything connected with farming. He planted seeds, tended the fields, and harvested and sold his crops. At the same time, he did many other jobs on the farm. However, he didn’t make the bricks for his house, grind the wheat for his flour, or cut his trees into boards. He also did not make the plows(犁), the work boots, or any of the other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those things.
Suppose there was another man we shall call Mr. Plowright. Using what he knew about farming and working with iron, Mr. Plowright invented a plow that made farming easier. Mr. Plowright did not really like farming himself and wanted to specialize in making really good  plows. Perhaps, he thought, other farmers will trade what they grow for one of my plows.
How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the shop door. It was probably all the information people needed to find Mr. Plowright and his really good plows.
Many historians believe that the first outdoor signs were used about five thousand years ago. Even before most people could read, they understood such signs. Shopkeepers would carve into stone, clay, or wood symbols for the products they had for sale.
A medium, in advertising talk, is the way you communicate your message. You might say that the first medium used in advertising was signs with symbols. The second medium was audio, or sound, although that term is not used exactly in the way we use it today. Originally, just the human voice and maybe some kind of simple instrument, such as a bell, were used to get people’s attention.
A crier, in the historical sense, is not someone who weeps easily. It is someone, probably a man, with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers might hire such a person to spread the news about their products. Often this primitive form of advertising involved a newly arrived ship loaded with goods. Perhaps the crier described the goods, explained where they came from, and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today’s world.
【小题1】What probably led to the start of advertisement?

Argentina in the late nineteenth century was an exciting place. Around 1870, it was experiencing an economic(经济的)boom, and the capital, Buenos Aires, attracted many people. Farmers, as well as a flood of foreigners from Spain and Italy, came to Buenos Aires seeking jobs. These jobs didn′t pay well, and the people felt lonely and disappointed with their new life in the city. As the unhappy newcomers mixed together in the poor parts of the city, the dance known an the tango(探戈舞)came into being
At the beginning the tango was a dance of the lower classes. It was danced in the bars and streets. At that time there many fewer women than men, so if a man didn′t want to be left out, his only choice was to dance with another man so that he could attract the attention of the few available women. Gradually, the dance spread into the upper classes of Argentinean society and became more respectable.
In Europe at this time, strong interest in dance from around the world was beginning
The interest in international dance was especially evident in Paris. Every kind of dance from ballet(芭蕾舞)to belly dancing could be found on the stages of the Paris theaters of the Paris theaters. After tango dances from Argentina arrive in Europe, they began to draw the interest of the public an they performed their exiting dance in cafes, Though not everyone approved of the new dance, saying it was a little too shocking, the dance did find enough supporters to make it popular.
The popularity（流行）Of the tango continued to grow in many other parts of the world. Soldiers who returned to the United States from World War I brought the tango to North America, It reached Japan in 1926, and in 2003 the Argentinean embassy in Seoul hired a local tango dancer to act an a kind of dance ambassador, and promote tango dancing throughout South Korea.
【小题1】The origin of the tango is associated with

【小题2】 Which of the following is true about the tango?

Most Americans would have a difficult time telling you, specifically, what the values are which Americans live by. They have never given the matter any thought.
Over the years I have introduced thousands of international visitors to life in the United States. This has caused me to try to look at Americans through the eyes of foreign visitors, I am confident that the values listed in this booklet describe most （but not all ）Americans, and that understanding these values can help you, the international visitor, understand Americans.
It is my belief that if foreign visitors really understand how deeply these 13 values are ingrained in Americans, they will then be able to understand 95% of American actions —actions which might otherwise appear “strange,”“ confusing,” or “unbelievable” when evaluated from the perspective （aspect） of the foreigner's own society and its values.
The different behaviors of a people or a culture make sense only when seen through the basic beliefs, assumptions and values of that particular group. When you encounter （meet） an action, or hear a statement in the United States which surprises you, try to see it as an expression of one or more of the values listed in this booklet.
【小题1】 An ordinary American can't tell you his / her value system because______.

Sometimes a program will be organized after the meal with dances, songs, or short talks followed by a question period．___【小题5】___  For this reason, a few weeks spent ‘hostelling’ can be just as useful a part of one’s education as classes in school.

February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.
On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest in the third century Rome. When the emperor (皇帝) decided that single men could become better soldiers than those with wives, he didn’t allow marriage.
But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint (圣徒), as well as becoming one of history’s most romantic characters.
Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heart-shaped cakes. The idea is to have fun and encourage people to share in the spirit of St. Valentine.
【小题1】Why did the emperor in Rome not allow marriage in his country?

Bungee jumping is not a new activity. Men on Pentecost Island in the South Pacific have been doing land jumping for hundreds of years. The men tie long vines(藤) from plants around their ankles（踝关节）. They spend days building tall towers out of vines and logs(圆木). Then they jump off them.
According to their beliefs, the first land diver was a woman. She decided to run away from her rude husband. So she climbed up a tall tree and tied some vines around her feet. Her husband also climbed up the tree and tried to catch her, but the woman jumped and the man followed. The vines saved her life, but her husband died.
This ancient custom caught the interest of some students at Oxford University in England. In the late 1970s, they formed a group called the Dangerous Sports Club. They were some of the first people to test several of what are now called extreme sports. They are said to have invented modern bungee jumping.
In the spring of 1979, members of the group jumped off the Clifton Suspension Bridge in Bristol, England. They were attached to the bridge by a bungee cord, a long elastic rope that stretches. The group soon received even more attention when they organized a bungee jump off the Golden Gate Bridge in San Francisco, California.
A man named A. J. Hackett of New Zealand decided to make the sport into a business. He started developing bungee ropes and material with a friend. They held a major jump in 1987 off the famous Eiffel Tower in Paris, France. They later got permission to open the first bungee jumping operation on the Kawarau Bridge in Queenstown, New Zealand. Many people paid 75 dollars to jump off the bridge with a bungee cord attached to their ankles.
【小题1】The second paragraph tries to tell us________________.

Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn't exist. That changed because of a man named Joseph Merlin. Merlin's work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of imagination, ideas and dreams. People called him a dreamer.
　　One day Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.
　　Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.
　　On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin's grand entrance for a long time!
