Friendship is a big statement. Lots of people are lovers but are not friends. Lots of people are relatives and are not friends. Lots of people who work together are not friends. You can appreciate or admire someone, but that does not mean that you make him or her a friend.

When I had my near-death illness last year and the following long recuperation, I had a lot of time to think about what makes someone a friend. If they are scared of you when you need help, sorry, that is not friendship. If their attitude is “for better or worse,” if they stick to you through troubles and difficulties, it is the time when you can tell it is true friendship. I do have some friends, but not as many as I thought. And there was a time, in the late 80s when my friend, Ken, really needed me but I did not come through for him. I remember hanging out in my happy suburban house in Menlo Park, and not coming to help him through the loss of his wife. Luckily, I got to apologize for that but Ken said he did not mind.

I do not have a tidy answer about Ken and me and friendship. Sometimes we were friends, and other times, clearly, not. But I guess there is something remarkable in two people overcoming the barriers to friendship to find some real communication at some point.

Read the following passage and choose the best answer (A, B, C, D):
Music can bring US to tears or to our feet, drive US into battle or lull US to sleep. Music is indeed remarkable in its power over all humankind, and perhaps for that every reason, no human culture on earth has ever lived without it. From discoveries made in France and Slovenia even Neanderthal man, as long as 53,000 years ago, had developed surprisingly sophisticated, sweet-sounding flutes carved from animal bones. It is perhaps then, no accident that music should strike such a chord with the limbic system - an ancient part of our brain, evolutionarily speaking, and one that we share with much of the animal kingdom. Some researchers even propose that music came into this world long before the human race ever did. For  example, the fact that whale and human music have so much in common even though our evolutionary paths have not interested for nearly 60 million years suggests that music may predate humans. They assert that rather than being the inventors of music, we are latecomers to the musical scene. Humpback whale composers employ many of the same tricks that human songwriters do. In addition to using similar rhythms, humpbacks keep musical phrases to a few seconds, creating themes out of several phrases before singing the next one. Whale songs in general are no longer than symphony movements, perhaps because they have a similar attention span. Even though they can sing over a range of seven octaves, the whales typically sing in key, spreading adjacent notes no farther apart than a scale. They mix percussive and pure tones in pretty much the same ratios as human composers - and follow their ABA form, in which a theme is presented, elaborated on and then revisited in a slightly modified form. Perhaps most amazingly, humpback whale songs include repeating refrains that rhyme. It has been suggested that whales might use rhymes for exactly the same reasons that we do: as devices to help them remember. Whale songs can also be rather catchy. When a few humpbacks from the Indian Ocean strayed into the Pacific, some of the whales they met there quickly changed their tunes - singing the new whales'songs within three short years. Some scientists are even tempted to speculate that a universal music awaits discovery.

There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama evolved from ritual. The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought, through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then retained and repeated until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths, persisted and provided material for art and drama. Those who believed that drama evolved out of ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site hard to be provided for the performances, and when the entire community did not participate, a clear division was usually made between the “acting area” and the “auditorium”. In addition, there were performers, and since considerable importance was attached to avoiding mistakes in the enactment of rites, religious leaders usually assumed that task. Wearing masks and costumes, they often impersonated other people, animals, or supernatural beings, and mimed the desired effect- success in hunt or battle, the coming rain, the revival of the Sun as an actor might. Eventually such dramatic representations were separated from religious activities. Another theory traces the theater’s origin from the human interest in storytelling. According to this view, tales (about the hunt, war or other feats) are gradually elaborated, at first through the use of impersonation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitation of animal movements and sounds.

Having a best friend to confide in can bring a positive effect on our emotional health. An evening out with the closest friend may be the best guarantee of a good time. In fact, our best friend can prevent us from developing serious psychological problems such as depression and anxiety.

Best friendship evolves with time – we cannot go out and pick our best friend. We become friends with people who share common interests – at school or through hobbies, for example.

Best friends have usually known each other for years and stuck together through good and bad times. If you haven’t got one, perhaps you are being too distant from people, or focusing too much on your work.

According to the passage, ________.

As computer use becomes more common, the need for security is more important than ever. One of the greatest security threats in the online world is computer hacking.
Computer hacking is the unauthorized access to a computer or network of computers. Hackers are people who illegally enter systems. They may alter or delete information, steal private information, or spread viruses that can damage or destroy files. But how exactly can a hacker get into a system to do these things? 
Most hackers use information called protocols that are built into computer software. These protocols allow computer to interact with one another. Protocols are sort of like computer police officers. When a computer connects to another system, the protocols check to see if the access is valid. The protocols can also determine how much information can be shared between the two systems. Hackers can manipulate the protocols to get unlimited access to a computer system. 
In fact, just the act of entering a computer network is considered hacking. This is commonly called passive hacking. Passive hackers get a rush from just being able to access a challenging system like a bank of military network. Another kind of hacker tries to do damage to a system. After hacking into systems, these hacker release viruses or alter, delete, or take information. Known as active hackers, they are, by far, the more dangerous of the two. 
The easiest way to protect a system is with a good password. Long and unusual passwords are harder for hackers to guess. For even greater security, some online services use “password-plus” systems. In this case, users first put in a password and then put in a second code that changes after the user accesses the site. Users either have special cards or devices that show them the new code to use the next time. Even if a hacker steals the password, they won’t have the code. Or if the hacker somehow gets the code, they still don’t know the password.

What does “plus” in “password-plus” in the passage probably mean?

A useful definition of an air pollutant is a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals vegetations, or materials adversely. Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled-a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions. Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentrations of these pollutants were altered by various chemical reactions; they became components in biogeochemical cycle. These serve as an air purifiation scheme by allowing the compounds to move from the air to the water or soil on a global basis, nature's output of these compounds dwarfs that resulting from human activities. However, human production usually occurs in a localized area, such as a city. In this localized regions, human output may be dominant and may temporarily overload the natural purifiation scheme of the cycle. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities.The actual concentration need not be large for a substance to be a pollutant; in fact the numerical value tells US little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.

   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 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 as he 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!

Amid the hum and heat of Berlin’s Reuter thermal power station stands a shining contraption that looks out of place in the decades-old machine hall. Its silver pipes and vats contain a substance that the company Vattenfall, the plant’s operator, says could become a key ingredient for a fossil fuel-free future. The energy company, together with a Swedish start-up, is testing the use of salt to store heat, which accounts for more than half the power consumed in Germany. If it works well, the system could help solve a problem posed by renewable energy sources like wind and solar: unreliability, meaning they sometimes generate too much, and sometimes too little power. “Germany currently has enough installed renewable energy capacity to produce twice as much as it needs, it’s just not constant,” says Hendrik Roeglin, who oversees the salt storage project for Vattenfall. At the Reuter power plant in Berlin, which supplies 600,000 households in the capital with heat, the solution involves the use of calcium oxide, also known as quicklime. Vattenfall and Swedish start-up SaltX have been taking advantage of a simple chemical reaction that occurs when quicklime becomes wet: the salt-like grains soak up the water, becoming calcium hydroxide and releasing large amounts of heat in the process. By removing the water again, the substance turns back into calcium oxide. The process essentially mirrors how batteries work, except that instead of electricity, the system stores heat. Roeglin says the process can absorb ten times more energy than water, which is currently used for power- to-heat facilities. And unlike tanks of hot water, which slowly cool down over time, the system can retain the chemically-trapped energy for far longer. Need heat? Just add water. The pilot project in Berlin can currently store enough energy to heat about 100 large houses. But SaltX says the facility could easily be scaled up and provide heat to any of the homes or offices already connected to the capital’s district heating system. Such networks — consisting of pipes pumping hot water or steam from power plants to consumers — exist in many European countries, Canada, the United States, Japan and China. SaltX also notes that the calcium oxide currently mined in Finland could be safely recycled, giving it an edge over some battery technologies that use rare or toxic materials. “If your ambition is to be fossil-free within a generation, you have to consider various alternatives to reach that,” a representative of SaltX, Simon Ahlin, said during a visit to the facility. “This is an effective solution that’s available in a short time frame.”

Butterflies are among the most extensively studied insects, an estimated 90 percent of the world's species have their scientific names. As a consequence, they are, perhaps, the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity. Perhaps the aspect of butterflies diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions. For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterflies' richness has been well confirmed. A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather than between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates. In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase. In documenting geographical variation in butterflies' diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfìy distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized

You can usually tell when your friends are happy or angry by the looks on their faces or by their actions. This is useful because reading their emotional expressions helps you to know how to respond to them. Emotions have evolved to help us respond to important situations and to convey our intentions to others. But does raising the eyebrows and rounding the mouth say the same thing in Minneapolis as it does in Madagascar ? Much research on emotional expressions has centered on such questions. According to Paul Ekman, the leading researcher in this area, people speak and understand substantially the same “facial language”. Studies by Ekman’s group have demonstrated that humans share a set of universal emotional expressions that testify to the common biological heritage of the human species. Smiles, for example, signal happiness and frowns indicate sadness on the faces of people in such far-flung places as Argentina, Japan, Spain, Hungary, Poland, Sumatra, the United States, Vietnam, the jungles of New Guinea, and the Eskimo villages north of Artic Circle. Ekman and his colleagues claim that people everywhere can recognize at least seven basic emotions: sadness, fear, anger, disgust, contempt, happiness, and surprise. There are, however, huge differences across cultures in both the context and intensity of emotional displays – the so-called display responses – expecially negative ones – while many American children are encouraged to express their feelings more openly. Regardless of culture, however, emotions usually show themselves, to some degree, in people’s behavior. From their first days in life, babies produce facial expressions that communicate their feelings. The ability to read facial expressions develops early, too. Very young children pay close attention to facial expressions, and by age five, they nearly equal adults in their skill at reading emotions on people’s faces. This evidence all points to a biological underpinning for our abilities to express and interpret a basic set of human emotions. Moreover, as Chales Dawin pointed out over a century ago, some emotional expressions seem to appear across species boundaries. Cross-cultural psychologists tell us that certain emotional responses carry different meanings in diferrent cultures. For example, what emotion do you suppose might be conveyed while sticking out your tounge ? For American, this might indicate disgust, while in China it can signify surprise. Likewise, a grin on an American face may indicate joy, while on a Japanese face it may just as easily mean embarrassment. Clearly, culture influences emotional expressions.

The stylistic innovation in painting known as Impressionism began in the 1870s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated on the play of light over objects, people, and nature, breaking up seemingly solid surfaces, stressing vivid contrast between colors in sunlight and shade, and depiction reflected light in all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoors to complete the work from memory. Some of the Impressionists' painting methods were affected by technological advances. For example, the shift from the studio to the open air was made possible in part by the advent of cheap rail travel, which permitted easy and quick access to the countryside or seashore, as well as by newly developed chemical dyes and oils that led to collapsible paint tubes, which enabled artists to finish their paintings on the spot. Impressionism acquired its name not from supporters but from angry art lovers who felt threatened by the new painting. The term "Impressionism" was born in 1874, when a group of artists who had been working together organized an exhibition of their paintings in order to draw public attention to their work. Reaction from the public and press was immediate, and derisive. Among the 165 paintings exhibited was one called Impression: Sunrise, by Claude Monet (1840- 1926), viewed through hostile eyes, Monet's painting of a rising sun over a misty, watery scene seemed messy, slapdash, and an affont to good taste. Borrowing Monet's title, art critics extended the term "Impressionism" to the entire exhibit. In response, Monet and his 29 fellow artists in the exhibit adopted the same name as a badge of their unity, despite individual differences. From then until 1886 Impressionism had all the zeal of a "church", as the painter Renoir put it. Monet was faithful to the Impressionist creed until his death, although many of the others moved on to new styles. 
6. The word "affont" in paragraph 4 is closest in meaning to: 

By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1860-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.
 Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The common-sense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the nice balance of insulation and circulation needed for an efficient icebox.
 But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

The generation gap, which refers to a broad difference between one generation and another, especially between young people and their parents, usually leads to numerous conflicts. Such family conflicts can seriously threaten the relationship between parents and children at times.
 
It goes without saying that, however old their children are, parents still regard them as small kids and keep in mind that their offspring are too young to protect themselves cautiously or have wise choices. Therefore, they tend to make a great attempt to help their children to discover the outside world. Nevertheless, they forget that as children grow up, they want to be more independent and develop their own identity by creating their own opinions, thoughts, styles and values about life.

One common issue that drives conflicts is the clothes of teenagers. While teens are keen on wearing fashionable clothes which try to catch up with the youth trends, parents who value traditional clothes believe that those kinds of attire violate the rules and the norms of the society. It becomes worse when the expensive brand name clothes teens choose seem to be beyond the financial capacity of parents.

Another reason contributing to conflicts is the interest in choosing a career path or education between parents and teenagers. Young people are told that they have the world at their feet and that dazzling future opportunities are just waiting for them to seize. However, their parents try to impose their choices of university or career on them regardless of their children's preference.

Indeed, conflicts between parents and children are the everlasting family phenomena. It seems that the best way to solve the matter is open communication to create mutual trust and understanding.

Which kinds of clothes do teenagers want to wear?

Most forms of property are concrete and tangible, such as houses, cars, furniture or anything else that is included in one’s possessions. Other forms of property can be intangible and copyright deals with intangible forms of property. Copyright is a legal protection extended to authors of creative works, for example, books, magazine articles, maps, films, plays, television shows, software, paintings, photographs, music, choreography in dance and all other forms of intellectual or artistic property. Although the purpose of artistic property is usually public use and enjoyment, copyright establishes the ownership of the creator. When a person buys a copyrighted magazine, it belongs to this individual as a tangible object. However, the authors of the magazine articles own the research and the writing that went into creating the articles. The right to make and sell or give away copies of books or articles belongs to the authors, publishers, or other individuals or organizations that hold the copyright. To copy an entire book or a part of it, permission must be received from the copyright owner, who will most likely expect to be paid. Copyright law distinguishes between different types of intellectual property. Music may be played by anyone after it is published. However, if it is performed for profit, the performers need to pay a fee, called a royalty. A similar principle applies to performances of songs and plays. On the other hand, names, ideas, and book titles are accepted. Ideas do not become copyrighted property until they are published in a book, a painting or a musical work. Almost all artistic work created before the 20th century is not copyrighted because it was created before the copyright law was passed. The two common ways of infringing upon the copyright are plagiarism and piracy. Plagiarizing the work of another person means passing it off as one’s own. The word plagiarism is derived from the Latin plagiarus, which means “abductor”. Piracy may be an act of one person, but, in many cases, it is a joint effort of several people who reproduce copyrighted material and sell it for profit without paying royalties to the creator. Technological innovations have made piracy easy and anyone can duplicate a motion picture on videotape, a computer program, or a book. Video cassette recorders can be used by practically anyone to copy movies and television programs, and copying software has become almost as easy as copying a book. Large companies zealously monitor their copyrights for slogans, advertisements, and
brand names, protected by a trademark.

Continents and ocean basins represent the largest identifiable bodies on Earth. On the solid portion of the planet, the second most prominent features are flat plains, elevated plateaus, and large mountain ranges. In geography, the term "continent" refers to the surface of continuous landmasses that together comprise about 29.2% of the planet's surface. On the other hand, another definition is prevalent in the general use of the term that deals with extensive mainlands, such as Europe or Asia,that actually represent one very large landmass. Although all continents are bounded by the water bodies or high mountain ranges, isolated mainlands, such as Greenland and India-Pakistan areas are called subcontinents. In some circles, the distinction between continents and large islands lies almost exclusively in the size of a particular landmass. The analysis of compression and tension in the earth's crust has determined that continental structures are composed of layers that underlie continental shelves. A great deal of disagreement among geologists surrounds the issue of exactly how many layers underlie each landmass because of their distincive mineral and chemical composition. It's also quite possible that the ocean floor rests on top of unknown continents that have not yet been explored. The continental crust is believed to have been forrmed by means of a chemical reaction when lighter materials separated from heavier ones,thus settling at various levels within the crust. Assisted by the measurements of the specifics within crust formations by means of monitoring earthquakes, geologists can speculate that a chemical split occured to form the atmosphere, sea water and the crust before it solidified many centuries ago. Although each continent has its special features, all consist of various combinations of components that include shields,moutain belts, intracratonic basins, margins, volcanic plateaus, and blockvaulted belts. The basic differences among continents lie in the proportion and the composition of these features relative to the continent size. Climatic zones have a crucial effect on the weathering and formation of the surface features, soil erosion, soil deposition, land formation, vegetation, and human activities. Moutian belts are elongated narrow zones that have a characteristic folded sedimentary organization of layers. They are typically produced during substabtial crustal movements, which generate faulting and moutain building. When continental margins collide, the rise of a marginal edge leads to the formation of large moutain ranges, as explained by the plate tectonic theory. This process also accounts for the occurrence of mountain belts in ocean basins and produces evidence for the ongoing continental plate evolution.

Many of the most damaging and life-threatening types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $ 250 million, the highest ever for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-live local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weather balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events. Until recently, the observation-intensive approach needed for accurate, very short-range forecasts, or "Nowcasts", was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyzing this large volume of weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.

By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1860-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.
 Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The common-sense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the nice balance of insulation and circulation needed for an efficient icebox.
 But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

According to the passage, when did the word "icebox" become part of the language of the United States?
