Listen to part of a conversation between two students. They are studying for an economics test. M: OK ... so what do we do next? W: Why don’t we go over the chapter on analysis of costs? That’ll be on the test. M: OK. W: Let’s start with “opportunity cost.” That part’s still confusing to me. I understand fixed cost and variable cost, and marginal cost, the cost of producing one more unit of something. I′m sure there’ll be a question about that on the test. But I don’t get “opportunity cost.” M: Opportunity cost that’s when you have to consider the things you give up when you make a certain decision. You have an opportunity cost when you’re forced to choose between different alternatives. W: OK. That sort of makes sense. M: Say you want to have your own business, so you. so you open a restaurant. You put in 60 hours a week, but you don′t pay yourself wages. At the end of the first year, your restaurant shows a profit of... um ... say. 30 thousand dollars—looks pretty good for a small business. But is it really that good? An economist would say no. because you have to count your own labor as a cost, even if you don’t get paid. You have to consider that you had alternative opportunities for work, and you have to count that lost opportunity as a cost. You could have taken a job at, say. an accounting firm and earned 50 thousand a year. This is the opportunity cost the earnings you gave up—because you decided to open your own business instead. W: OK. So what that means is ... um ... if I lost 50 thousand dollars by not taking an accounting job. then ... my restaurant′s profit of 30 thousand isn’t that great after all—at least in an economic sense. Maybe I had more enjoyment, though I mean the enjoyment of being my own boss. M: Right. But your enjoyment comes with a cost. An economist would say the real profit of your restaurant isn’t 30 thousand dollars. You’d have to subtract the 50 thousand opportunity cost of your own labor. When you subtract 50 thousand from 30 thousand, you find you have a net loss of 20 thousand dollars! W: Wow! That means the enjoyment of having my own business cost me 20 thousand dollars! M: Yeah. Something like that. W: This is really different from what we learned about costs in my accounting class. I think an accountant would say my 30 thousand -dollar profit made me a viable business. But an economist—if I understand it correctly—an economist would say my business is a loser! M: Right. And that’s because an economist tries to look at all the factors, all the costs. An economist would count the opportunity cost. W: An economist looks at the big picture. M: Right. An economists definition of costs is broader than an accountants. Opportunity cost is actually a very broad concept. It takes into account the cost of the choices we make. When we choose one thing, we have to give up something else. W: That′s right. We chose to go to college, so that means we had to give up full time employment, for the time being. M: Right! So, how do you measure the true cost of a college education? W: Well, it′s more than what we pay for tuition and books! We have to subtract the income we lose by not working full time. M: Yeah, and that′s why college is really more expensive than it seems.

Listen to a conversation between two students. W: Our design class is getting really interesting, don′t you think? M: Yeah. I like Professor Vargas, but sometimes he goes too fast, and I feel like I′m missing something. There’s a lot we have to remember. W: True. There are a lot of details about all the different styles. M: Yeah, there′s Art Nouveau, and Art Deco, and Art Moderne ... I have a hard time keeping it all straight. W: I know what you mean. M: For example, it seems to me that Art Deco and Art Moderne are the same thing. W: Well, there is some overlap. They were both popular in the 1930s, although Art Deco came a little before Moderne. I think Professor Vargas said Art Deco started at an exhibition in Paris in 1925. M: So, they were about the same time. That′s one thing that gets confusing. Another thing is, they seem so similar it’s hard to see why they′re considered different styles. W: Art Deco has more decoration than Art Moderne. Art Deco is the style you see in a lot of movie theaters and hotels that were built in the twenties and thirties. It has facades with geometric designs ... and uh ... strips of windows with decorative spandrels. Art Deco uses a lot of straight lines and slender forms. “Sleekness” is the word that comes to mind. At the time, it was considered “modernistic”. M: But that′s what gets confusing! Doesn′t “modernistic” also apply to Art Moderne? W: Art Moderne is simpler than Deco. It has ... uh ... things like more rounded corners. Hat roofs, and ... the walls are smooth and don’t have any decoration. It’s more streamlined than Deco. Art Moderne buildings remind me of boats. The walls are smooth, and the trim is usually stainless steel. A lot of the windows are round, kind of like the portholes on a boat. M: Oh ... I know a building like that. It′s right here in town, on Second Avenue. It has a rounded corner and round windows. It used to be a gas station, but now it’s a restaurant. We should go there sometime. W: Yeah, I′d like to see that. My favorite building is the Maritime Building. It’s downtown, right across from my father′s office. Its Art Deco -built in 1927—I know that from the cornerstone. You should see the lobby! It′s just beautiful. There’s a geometric pattern in the tile on the floor kind of a big circle with lots of triangles. And you should see the elevator doors. They’re gorgeous. M: You know we should go around and look at some of these buildings. W: Yeah, that would be fun. M: And ... you know what else ... this is an idea Tor our project. We could take pictures of the buildings and do a slide show in class. W: Oh, that′s a cool idea! But don’t we need to get permission to take photographs? Especially of the interior ... we need pictures of the lobby of the Maritime Building. M: We could ask for permission. That shouldn′t be a problem. Let’s talk to Professor Vargas and see what he thinks. W: OK. Why don′t you do that, and I’ll go down to the Maritime Building and see if there′s anyone there— like a building superintendent—who can give us permission. I’ll let you know. Why don’t we meet again on Thursday? M: OK. Fine with me.

Listen to part of a talk in a business management class. What do we mean when we talk about leadership? First, it’s important not to confuse leadership with power. It’s true that— by definition—leaders always have some degree of power. Leaders have power because of their ability to influence other people. However, many power holders do not have the qualities of leadership. Consider the headwaiter in your favorite restaurant. The headwaiter has power to some degree—for example, the power to scat you at the best table by the window-—but he doesn′t necessarily have the qualities we associate with leadership. We have to distinguish between leaders and power holders. There are a lot of powerful people who lack leadership skills. A military dictator has power. So does the robber who sticks a gun in your face and demands your wallet. Leadership is something else. Leadership and power arc not the same thing, although they are similar in this one way. Both leadership and power involve the ability to ... bring about the results you want, and to ... prevent the results that you don’t want to happen. Here′s another way to think of it. In sociological terms, uh ... power is simply the ability to bring about certain behavior in other people. For example, parents have power over their children, and they use it to get their children to behave in acceptable ways. Teachers have power, and so do mid-level managers—all as a result of their position. Where does power come from? The sources are varied. Probably the oldest source of power is the ability to use physical force—a source available to both the military and the biggest kid on the playground. The power that comes from physical might is not the same as leadership. Just think of the military dictator... or the school bully. We don’t usually think of these power holders as leaders—despite the brute force they use to control others. Wealth, position, the ability to motivate - all of these are sources of power. Being close to others with power is a source of power. That’s why people gravitate toward political leaders. Some power comes from qualities people were born with -like physical beauty, or the ability to influence friends. Science and technology are also sources of power. Corporations understand this and spend huge amounts of money on research, information systems, and consultants. Although leadership and power arc different things, they′re related in important ways. Consider, for example, a chief executive officer who has the ability to motivate people, a CEO with vision, who can lift the spirit of his or her employees and bring about a rise in productivity—that is leadership. But consider this scenario. The company realizes they′re sort of falling behind in the technology race, so the CF.O responds by increasing the amount of money available to the company’s research division. That is the exercise of power. Authorizing a spending increase could have been made only by a chief executive with the power to do so. Remember, both leadership and power involve the ability to accomplish the results you want, and successful managers understand how the two work together to make this happen.

A botanist has been invited to speak to a geography class. She will be discussing aromatic trees of North America. Listen to part of the talk. When European explorers first approached the coast of North America, even before their ships landed, the first thing they noticed was the pungent aroma carried to the ships by the offshore breezes. Some sea captains thought this aroma was the scent of the valuable Oriental spices that had prompted their voyages of exploration. But in fact, the agreeable smells didn’t come from spices: they came from the lush vegetation of the North American forests. The fragrance came from the blossoms of numerous trees and from the volatile oils in pine sap. Pine sap is a resinous fluid that pine trees put out to heal wounds caused by wind, fire, and lightning, and also to protect the pine tree’s seeds. Pine sap was a valuable commodity to the sailors who explored the coast. The smell of pine meant there was an abundant supply of what were known as naval stores pitch and pine tar. Pitch and pine tar were thick, sticky, semi-solid substances that were made by distilling pinewood. Sailors used naval stores for caulking and waterproofing their wooden ships, which kept them seaworthy. The Europeans found fragrant trees all along the Atlantic coast, from Massachusetts in the north to Florida in the south. Everywhere along the coast, the air was filled with the strong perfume of the flowering dogwood. The Native Americans already knew about the medicinal properties of the dogwood, and they used its bark and roots to treat malaria and other fevers. They brewed the aromatic bark into a bitter, astringent tea. European settlers also used the dogwood to relieve attacks of malaria. They soaked the dogwood bark in whiskey and drank the strong infusion. This was before they knew’ about quinine from South America, and before quinine became available. In the south, probably the best-known aromatic tree was the sassafras. The sassafras is a fast growing tree, a member of the laurel family. Like the other fragrant laurels cinnamon, bay. and camphor sassafras is noted for its aromatic bark, leaves, roots, flowers, and fruit. I have a sassafras twig with me here, which I′ll pass around so you can all enjoy its smell. Just give it a small scrape with your thumbnail to release the scent. I think you’ll find it strong but pleasant. The Choctaw Indians used powdered sassafras leaves as a spice. Other Native American tribes used sassafras tonic as a cure for everything from fever to stomachache. News of this wonder tree reached Europe in the sixteenth century by way of the French and the Spanish, and sassafras was one of the first exports from North America to Europe. It sold for a high price on the London market, which sort of inspired other English explorers to ... um ... seek their fortunes in the North American colonies. For centuries, sassafras enjoyed a fantastic reputation as a cure for almost every disease. Maybe you′ve heard of the medicinal spring tonic of the old days. Well, sassafras was a main ingredient in spring tonic—the stuff pioneer parents gave their kids. My grandmother had to take the spring tonic that her grandmother made from sassafras. Sassafras leaves, bark, and roots used to provide the flavoring for root beer and chewing gum. Sassafras was also used in soaps and perfumes. However, in the 1960s, the United States Food and Drug Administration found sassafras oil to be a potential carcinogen for humans because it caused cancer in rats. Since that time, sassafras has been banned for human consumption. No one really knows just how harmful it is to human beings, but some studies show that one cup of strong sassafras tea contains more than four times the amount of the volatile oil safrole that is hazardous to humans if consumed on a regular basis.

Listen to a discussion between a student and her tutor. W: My first test in computer science is on Monday, and I’m sure there′ll be a question about memory. So, can we go over memory again? M: Sure. Just remember the term "memory” is used a bit loosely. It describes an important element inside the system unit—the part of your computer where information is stored. Technically, memory can be either of two things: RAM or ROM. W: RAM and ROM—two kinds of memory. I need to be able to explain them. Now, what′s the difference between RAM and ROM? M: RAM—or random -access memory—stores the programs and data you′re using in your current work session. When you turn off the computer, the information in RAM is lost. ROM—read- only memory— stores the information your computer needs to perform basic functions and run programs that are built into your computer ... like the program to start up the computer. ROM is permanent memory. W: OK. You said RAM stores the programs and the data. OK, then what does the hard disk store? I guess I don’t understand the difference between the memory and the disk storage. M: That’s a really good question. I′ll answer it with an analogy. Imagine you’re at the library, doing research for a new product your company wants to make. You′ve found a cabinet of one hundred file folders with all the information you need. You also have five sheets of instructions from your boss on how to use the information. So, what do you do? You sit down at a table, open several folders, and lay out only the instruction sheet you need for this part of tile research. After all, the library table is only so big. When you finish gathering data from the first set of folders, you put them back and get another bunch. Similarly, when you complete the first page of your boss′s instructions, you put that page back in your briefcase and pull out another page. Now, which part of your computer′s memory is sort of like the library table? W: RAM? M: That′s right. RAM. Why is that? W: Because RAM stores only the program and data I need for this part of mv W0ĩkẳ RAM is sort of my work area—the tabletop—it’s what 1 use when I work with files in a program. M: That′s right. And what are the one hundred file folders? W: I get it now. The file folders are the disk storage. In a program, when I ask for another file, the computer gets it from the disk—the file cabinet—and loads it into RAM. What I mean is, it sort of puts the file on my work table. M: That′s right! And by keeping in RAM only the files needed for your current work session, you can work much faster and more efficiently. When you’re finished, before you leave the library, you clear the table and return all the folders to the cabinet. It′s exactly like what the computer docs. When you finish your work session on the computer, all the files are returned to disk storage.

FACTORS THAT INFLUENCE TIDES Tides are a natural phenomenon involving the alternating rise and fall in the earth’s large bodies of water caused by the gravitational pull of the moon and the sun. The combination of these two variable forces produces the complex recurrent cycle of the tides. Tides may occur in both oceans and seas, to a limited extent in large lakes, the atmosphere, and, to a very minute degree, in the earth itself. The force that generates tides results from the interaction of two forces: the centrifugal force produced by the revolution of the earth around the center-of-gravity of the earth - moon system; and the gravitational attraction of the moon acting upon the earth’s waters. Although the moon is only 238,852 miles from the earth, compared with the sun’s much greater distance of 92,956,000 miles, the moon’s closer distance outranks its much smaller mass, and thus the moon’s tide-raising force is more than twice that of the sun. The tide-generating forces of the moon and sun ‘cause a maximum accumulation of the waters of the oceans at two opposite positions on the earth’s surface. At the same time, compensating amounts of water are drawn from all points 90 degrees away from these tidal bulges. As the earth rotates, a sequence of two high tides and two low tides is produced each day. Successive high tides occur on an average of 12.4 hours apart. High tide at any given location occurs when the moon is overhead and low tide when it is at either horizon. The highest and lowest levels of high tide, called spring tide and neap tide, each occur twice in every lunar month of about 27.5 days. A spring tide occurs at the new moon and at the full moon, when the moon and earth are lined up with the sun, and thus the moon’s pull is reinforced by the sun’s pull. At spring tide, the difference between high and low tides is the greatest. A neap tide, the lowest level of high tide, occurs when the sun-to- earth direction is at right angles to the moon-to-earth direction. When this happens, the gravitational forces of the moon and sun counteract each other: thus, the moon’s pull is at minimum strength, and the difference between high and low tides is the least. Spring and neap tides at any given location have a range of about 20 percent more or less, respectively, than the average high tide. The vertical range of tides—the difference between high and low—varies according to the size, surface shape, and bottom topography of the basin in which tidal movement occurs. In the open water of the central Pacific, the range is no more than about a foot; in the relatively small, shallow North Sea, it is about 12 feet. Along the narrow channel of the Bay of Fundy in Nova Scotia, the difference between high and low tides may reach 45 feet under spring tide conditions—the world’s widest tidal range. At New Orleans, which is at the mouth of the Mississippi River, the periodic rise and fall of the tides varies with the river’s stage, being about ten inches at low stage and zero at high. In every case, actual high or low tide can vary considerably from the average. Several factors affect tidal ranges, including abrupt changes in atmospheric pressure or prolonged periods of extreme high or low pressure. (1) They are also influenced by the density and volume of seawater, variations in ocean-current velocities, earthquakes, and the growing or shrinking of the world’s glaciers. (2) In fact, any of these factors alone can alter sea level. (3) The greater and more rapid the change of water level, the greater the erosive effect of the tidal action, and thus in the amount of material transported and deposited on the shore. (4)

EARLY AUTOS America’s passion for the automobile developed rather quickly in the beginning of the twentieth century. At the turn of that century, there were few automobiles, or horseless carriages, as they were called at the time, and those that existed were considered frivolous playthings of the rich. They were rather fragile machines that sputtered and smoked and broke down often; they were expensive toys that could not be counted on to get one where one needed to go; they could only be afforded by the wealthy class, who could afford both the expensive upkeep and the inherent delays that resulted from the use of a machine that tended to break down time and again. These early automobiles required repairs so frequently both because their engineering was at an immature stage and because roads were unpaved and often in poor condition. Then, when breakdowns occurred, there were no services such as roadside gas stations or tow trucks to assist drivers needing help in their predicament. Drivers of horse-drawn carriages considered the horseless mode of transportation foolhardy, preferring instead to rely on their four-legged “engines,” which they considered a tremendously more dependable and cost-effective means of getting around. Automobiles in the beginning of the twentieth century were quite unlike today’s models. Many of them were electric cars, even though the electric models had quite a limited range and needed to be recharged frequently at electric charging stations; many others were powered by steam, though it was often required that drivers of steam cars be certified steam engineers due to the dangers inherent in operating a steam-powered machine. The early automobiles also lacked much emphasis on body design; in fact, they were often little more than benches on wheels, though by the end of the first decade of the century they had progressed to leather-upholstered chairs or sofas on thin wheels that absorbed little of the incessant pounding associated with the movement of these machines. In spite of the rather rough and undeveloped nature of these early horseless carriages, something about them grabbed people’s imagination, and their use increased rapidly, though not always smoothly. In the first decade of the last century, roads were shared by the horse-drawn and horseless variety of carriages, a situation that was rife with problems and required strict measures to control the incidents and accidents that resulted when two such different modes of transportation were used in close proximity. New York City, for example, banned horseless vehicles from Central Park early in the century because they had been involved in so many accidents, often causing injury or death; then, in 1904, New York state felt that it was necessary to control automobile traffic by placing speed limits of 20 miles per hour in open areas, 15 miles per hour in villages, and 10 miles per hour in cities or areas of congestion. However, the measures taken were less a means of limiting use of the automobile and more a way of controlling the effects of an invention whose use increased dramatically in a relatively short period of time. Under 5,000 automobiles were sold in the United States for a total cost of approximately $5 million in 1900, while considerably more cars, 181,000, were sold for $215 million in 1910, and by the middle of the 1920s, automobile manufacturing had become the top industry in the United States and accounted for 6 percent of the manufacturing in the country.

THE DEVELOPMENT OF REFRIGERATION Cold storage, or refrigeration, is keeping food at temperatures between 32 and 45 degrees F in order to delay the growth of microorganisms—bacteria, molds, and yeast— that cause food to spoil. Refrigeration produces few changes in food, so meats, fish, eggs, milk, fruits, and vegetables keep their original flavor, color, and nutrition. Before artificial refrigeration was invented, people stored perishable food with ice or snow to lengthen its storage time. Preserving food by keeping it in an ice-filled pit is a 4,000-year-old art. Cold storage areas were built in basements, cellars, or caves, lined with wood or straw, and packed with ice. The ice was transported from mountains, or harvested from local lakes or rivers, and delivered in large blocks to homes and businesses. Artificial refrigeration is the process of removing heat from a substance, container, or enclosed area, to lower its temperature. The heat is moved from the inside of the container to the outside. A refrigerator uses the evaporation of a volatile liquid, or refrigerant, to absorb heat. In most types of refrigerators, the refrigerant is compressed, pumped through a pipe, and allowed to vaporize. As the liquid turns to vapor, it loses heat and gets colder because the molecules of vapor use energy to leave the liquid. The molecules left behind have less energy and so the liquid becomes colder. Thus, the air inside the refrigerator is chilled. Scientists and inventors from around the world developed artificial refrigeration during the eighteenth and nineteenth centuries. (1) William Cullen demonstrated artificial refrigeration in Scotland in 1748, when he let ethyl ether boil into a partial vacuum. In 1805, American inventor Oliver Evans designed the first refrigeration machine that used vapor instead of liquid. (2) In 1842, physician John Gorrie used Evans’s design to create an air-cooling apparatus to treat yellow-fever patients in a Florida hospital. (3) Gorrie later left his medical practice and experimented with ice making, and in 1851 he was granted the first U.S. patent for mechanical refrigeration. (4) In the same year, an Australian printer, James Harrison, built an ether refrigerator after noticing that when he cleaned his type with ether it became very cold as the ether evaporated. Five years later, Harrison introduced vapor-compression refrigeration to the brewing and meatpacking industries. Brewing was the first industry in the United States to use mechanical refrigeration extensively, and in the 1870s, commercial refrigeration was primarily directed at breweries. German-born Adolphus Busch was the first to use artificial refrigeration at his brewery in St. Louis. Before refrigeration, brewers stored their beer in caves, and production was constrained by the amount of available cave space. Brewing was strictly a local business, since beer was highly perishable and shipping it any distance would result in spoilage. Busch solved the storage problem with the commercial vapor-compression refrigerator. He solved he shipping problem with the newly invented refrigerated railcar, which was insulated with ice bunkers in each end. Air came in on the top, passed through the bunkers, and circulated through the car by gravity. In solving Busch’s spoilage and storage problems, refrigeration also revolutionized an entire industry. By 1891, nearly every brewery was equipped with mechanical refrigerating machines. The refrigerators of today rely on the same basic principle of cooling caused by the rapid evaporation and expansion of gases. Until 1929, refrigerators used toxic gases— ammonia, methyl chloride, and sulfur dioxide—as refrigerants. After those gases accidentally killed several people, chlorofluorocarbons (CFCs) became the standard refrigerant. However, they were found to be harmful to the earth’s ozone layer, so refrigerators now use a refrigerant called HFC 134a, which is less harmful to the ozone.

AQUATIC SCHOOLS Many species of fish, particularly smaller fish, travel in schools, moving in tight formations often with the precision of the most highly disciplined military unit on parade. (1) Some move in synchronized hordes, while others move in starkly geometric forms. (2) In addition to the varieties of shapes of schools of fish, there are countless varieties of schooling behaviors. (3) Some fish coalesce into schools and then spread out in random patterns, while others move into close formations at specific times, such as feeding times, but are more spread out at other times. (4) Some move in schools composed of members of all age groups, while others move in schools predominantly when they are young but take up a more solitary existence as they mature. Though this behavior is quite a regular, familiar phenomenon, there is much that is not completely known about it, particularly the exact function that it serves and what mechanisms fish use to make it happen. Numerous hypotheses have been proposed and tested concerning the purpose of schooling behavior in fish. Schooling certainly promotes the survival of the species, but questions arise as to the way the schooling enables fish to have a better chance of surviving. Certainly, the fact that fish congregate together in schools helps to ensure their survival in that schooling provides numerous types of protection for the members of the school. One form of protection derives from the sheer numbers in the school. When a predator attacks a school containing a huge number of fish, the predator will be able to consume only a small percentage of the school. Whereas some of the members of the school will be lost to the predator, the majority of the school will be able to survive. Another form of protection comes from the special coloration and markings of different types of fish. Certain types of coloration or markings such as stripes or patterns in vibrant and shiny colors create a visual effect when huge numbers of the fish are clustered together, making it more difficult for a potential predator to focus on specific members of the school. A final form of protection comes from a special sense that fish possess, a sense that is enhanced when fish swim in schools. This special sense is related to a set of lateral line organs that consist of rows of pores leading to fluid-filled canals. These organs are sensitive to minute vibrations in the water. The thousands of sets of those special organs in a school of fish together can prove very effective in warning the school about an approaching threat. (1) It is also unclear exactly how fish manage to maintain their tight formations. (2) Sight seems to play a role in the ability of fish to move in schools, and some scientists believe that, at least in some species, sight may play the principal role. (3) However, many experiments indicate that more than sight is involved. Some fish school quite well in the dark or in murky water where visibility is extremely limited. (4) This indicates that senses other than eyesight must be involved in enabling the schooling behavior. The lateral line system most likely plays a significant role in the ability of fish to school. Because these lateral line organs are sensitive to the most minute vibrations and currents, this organ system may be used by fish to detect movements among members of their school even when eyesight is limited or unavailable.

CANADIAN ENGLISH Canadian English is a regional variety of North American English that spans almost the entire continent. Canadian English became a separate variety of North American English after the American Revolution, when thousands of Loyalists, people who had supported the British, left the United States and fled north to Canada. Many Loyalists settled in southern Ontario in the 1780s, and their speech became the basis for what is called General Canadian, a definition based on the norms of urban middle-class speech. Modern Canadian English is usually defined by the ways in which it resembles and differs from American or British English. Canadian English has a great deal in common with the English spoken in the United States, yet many Americans identify a Canadian accent as British. Many American visitors to Canada think the Canadian vocabulary sounds British—for example, they notice the British “tap” and “braces” instead of the American “faucet” and “suspenders.” On the other hand, many British people identify a Canadian accent as American, and British visitors think the Canadians have become Americanized, saying “gas” and “truck” for “petrol” and “lorry.” People who live outside North America often find it difficult to hear the differences between Canadian and American English. There are many similarities between the two varieties, yet they are far from identical. Canadian English is instantly recognizable to other Canadians, and one Canadian in a crowded room will easily spot the other Canadian among the North Americans. There is no distinctive Canadian grammar. The differences are mainly in pronunciation, vocabulary, and idioms. Canadian pronunciation reflects the experience of a people struggling for national identity against two strong influences. About 75 percent of Canadians use the British “zed” rather than the American “zee” for the name of the last letter of the alphabet. On the other hand, 75 percent of Canadians use the American pronunciation of “schedule,” “tomato,” and “missile.” The most obvious and distinctive feature of Canadian speech is probably its vowel sound, the diphthong “ou.” In Canada, “out” is pronounced like “oat” in nearby U.S. accents. There are other identifying features of Canadian vowels; for example, “cot” is pronounced the same as “caught” and “collar” the same as “caller.” An important characteristic of the vocabulary of Canadian English is the use of many words and phrases originating in Canada itself, such as “kerosene” and “chesterfield” (“sofa”). Several words are borrowed from North American Indian languages, for example, “kayak,” “caribou,” “parka,” and “skookum” (“strong”). The name of the country itself has an Indian origin; the Iroquois word “kanata” originally meant “village.” A number of terms for ice hockey—“face-off,” “blue-line,” and “puck”—have become part of World Standard English. Some features of Canadian English seem to be unique and are often deliberately identified with Canadian speakers in such contexts as dramatic and literary characterizations. Among the original Canadian idioms, perhaps the most famous is the almost universal use of “eh?” as a tag question, as in “That’s a good movie, eh?” “Eh” is also used as a filler during a narrative, as in “I’m walking home from work, eh, and I’m thinking about dinner. I finally get home, eh, and the refrigerator is empty.” The traditional view holds that there are no dialects in Canadian English and that Canadians cannot tell where other Canadians are from just by listening to them. The linguists of today disagree with this view. While there is a greater degree of homogeneity in Canadian English compared with American English, several dialect areas do exist across Canada. Linguists have identified distinct dialects for the Maritime Provinces, Newfoundland, the Ottawa Valley, southern Ontario, the Prairie Provinces, the Arctic North, and the West. diphthong: a speech sound that begins with one vowel and changes to another vowel
