Urban Climates

The city is an extraordinary processor of mass and energy and has its own metabolism. A daily input of water, food, and energy of various kinds is matched by an output of sewage, solid waste, air pollutants, energy, and materials that have been transformed in some way. The quantities involved are enormous. Many aspects of this energy use affect the atmosphere of a city, particularly in the production of heat.

In winter the heat produced by a city can equal or surpass the amount of heat available from the Sun. All the heat that warms a building eventually transfers to the surrounding air, a process that is quickest where houses are poorly insulated. But an automobile produces enough heat to warm an average house in winter, and if a house were perfectly insulated, one adult could also produce more than enough heat to warm it. Therefore, even without any industrial production of heat, an urban area tends to be warmer than the countryside that surrounds it.

The burning of fuel, such as by cars, is not the only source of this increased heat. Two other factors contribute to the higher overall temperature in cities. The first is the heat capacity of the materials that constitute the city, which is typically dominated by concrete and asphalt. During the day, heat from the Sun can be conducted into these materials and stored—to be released at night. But in the countryside materials have a significantly lower heat capacity because a vegetative blanket prevents heat from easily flowing into and out of the ground. The second factor is that radiant heat coming into the city from the Sun is trapped in two ways: (1) by a continuing series of reflection among the numerous vertical surfaces that buildings present and (2) by the dust dome, the cloudlike layer of polluted air that most cities produce. Shortwave radiation from the Sun passes through the pollution dome more easily than outgoing longwave radiation does; the latter is absorbed by the gaseous pollutants of the dome and reradiated back to the urban surface.

Cities, then, are warmer than the surrounding rural areas, and together they produce a phenomenon known as the urban heat island. Heat islands develop best under particular conditions associated with light winds, but they can form almost any time. The precise configuration of a heat island depends on several factors. For example, the wind can make a heat island stretch in the direction it blows. When a heat island is well developed, variations can be extreme; in winter, busy streets in cities can be 1.7℃ warmer than the side streets. Areas near traffic lights can be similarly warmer than the areas between them because of the effect of cars standing in traffic instead of moving. The maximum differences in temperature between neighboring urban and rural environments is called the heat-island intensity for that region. In general, the larger the city, the greater its heat-island intensity. The actual level of intensity depends on such factors as the physical layout, population density, and productive activities of a metropolis.

The surface-atmosphere relationships inside metropolitan areas produce a number of climatic peculiarities. For one thing, the presence or absence of moisture is affected by the special qualities of the urban surface. With much of the built-up landscape impenetrable by water, even gentle rain runs off almost immediately from

rooftops, streets, and parking lots. Thus, city surfaces, as well as the air above them, tend to be drier between episodes of rain; with little water available for the cooling process of evaporation, relative humidities are usually lower. Wind movements are also modified in cities because buildings increase the friction on air flowing around them. This friction tends to slow the speed of winds, making them far less efficient at dispersing pollutants. On the other hand, air turbulence increases because of the effect of skyscrapers on airflow. Rainfall is also increased in cities. The cause appears to be in part greater turbulence in the urban atmosphere as hot air rises from the built-up surface.

Paragraph 1: The city is an extraordinary processor of mass and energy and has its own metabolism.

The quantities involved are enormous. Many aspects of this energy use affect the atmosphere of a city, particularly in the production of heat.

1. The word “enormous” in the passage is closest in meaning to

○ growing

○ frightening

○ very large

○ strictly controlled

Paragraph 2: In winter the heat produced by a city can equal or surpass the amount of heat available from the Sun. All the heat that warms a building eventually transfers to the surrounding air, a process that is quickest where houses are poorly insulated. But an automobile produces enough heat to warm an average house in winter, and if a house were perfectly insulated, one adult could also produce more than enough heat to warm it. Therefore, even without any industrial production of heat, an urban area tends to be warmer than the countryside that surrounds it.

2. The word “surpass” in the passage is closest in meaning to

○ remain below

○ be higher than

○ add to

○ come close to

3. According to paragraph 2, how soon heat from a warmed house reaches the outside air greatly affected by

○ how well the house is heated

○ how well the house is insulated

○ how many adults live in the house

○ how much sunshine the house receives

Paragraph 3: The burning of fuel, such as by cars, is not the only source of this increased heat. Two other factors contribute to the higher overall temperature in cities. The first is the heat capacity of the materials that constitute the city, which is typically dominated by concrete and asphalt. During the day, heat from the Sun can be conducted into these materials and stored—to be released at night.

Shortwave radiation from the Sun passes through the pollution dome more easily than outgoing longwave radiation does; the latter is absorbed by the gaseous pollutants of the dome and reradiated back to the urban surface.

4. According to paragraph 3, each of the following contributes to making urban areas warmer than the surrounding countryside EXCEPT

○ the fuel burned by motor vehicles

○ the capacity to store heat of the materials used in building a city

○ the easy flow of heat into the ground in city areas covered by vegetation

○ the repeated reflection of solar radiation back and forth among buildings

5. According to paragraph 3, why do materials in the countryside have a lower heat capacity than materials in cities do?

○ The countryside in the Sun is the only important source of heat.

○ Construction materials in the city are not as good at keeping buildings warm as they are in the countryside.

○ In the countryside the solar heat that flows into the ground flows out again quickly.

○ Countryside vegetation prevents heat from being trapped in the ground.

6. How is paragraph 3 organized?

○ It describes two factors that contribute to the increased heat of cities and then provides two causes for the second factor.

○ It describes two causes discovered in an early analysis of the increased heat of cities.

○ It describes two factors that contribute to the increased heat of cities and two other factors that work against it.

○ It describes two well-established causes of the increased heat of cities and other two whose roles are less well understood.

Paragraph 4: Cities, then, are warmer than the surrounding rural areas, and together they produce a phenomenon known as the urban heat island. Heat islands develop best under particular conditions associated with light winds, but they can form almost any time. The precise configuration of a heat island depends on several factors.

7.The word “configuration” in the passage is closest in meaning to

○ location

○ history

○ temperature

○ shape

8. According to paragraph 4, what can explain the substantial differences in temperature between one area and other within a well-developed heat island?

○ The overall size of the heat island that includes the two reasons

○ The intensify of the heat island that includes the two areas

○ Differences between the two areas in the general level of activity, including traffic

○ Differences between the two areas in the insulation materials used in construction

9. Paragraph 4 supports the idea that a city’s heat-island intensity would increase if

○ the city went into an economic decline and lost population

○ the city’s economy shifted from heavy industry to health care and education

○ there was an upward trend in the average age of the city’s residents

○ repair work on the streets slowed traffic throughout the city

Paragraph 5: The surface-atmosphere relationships inside metropolitan areas produce a number of climatic peculiarities.

Rainfall is also increased in cities. The cause appears to be in part greater turbulence in the urban atmosphere as hot air rises from the built-up surface.

10. According to paragraph 5, surfaces in the city are generally drier than surfaces in the countryside between periods of rainfall because

○ in the city gentle rain is much more common than heavy rain

○ high temperatures in the city speed up the process of evaporation

○ in the city there are longer periods of dry weather between episodes of rain

○ rainwater in the city cannot soak into most surfaces and quickly runs off

11. The word “modified” in the passage is closest in meaning to

○ changed

○ blocked

○ increased

○ weakened

12. According to paragraph 5, which of the following is a factor responsible for the greater air turbulence in urban environments?

○ The high speed of the winds travelling above cities

○ The greater rainfall totals recorded in cities

○ Attempts to reduce urban air pollution

○ The effects of tall buildings on airflow

Paragraph 4: Cities, then, are warmer than the surrounding rural areas, and together they produce a phenomenon known as the urban heat island.

Seventeenth-Century Dutch Agriculture

Agriculture and fishing formed the primary sector of the economy in the Netherlands in the seventeenth century. Dutch agriculture was modernized and commercialized new crops and agricultural techniques raised levels of production so that they were in line with market demands, and cheap grain was imported annually from the Baltic region in large quantities. According to estimates, about 120,000 tons of imported grain fed about 600,000 people: that is about a third of the Dutch population. Importing the grain, which would have been expensive and time consuming for the Dutch to have produced themselves, kept the price of grain low and thus stimulated individual demand for other foodstuffs and consumer goods.

Apart from this, being able to give up labor-intensive grain production freed both the land and the workforce for more productive agricultural divisions. The peasants specialized in livestock husbandry and dairy farming as well as in cultivating industrial crops and fodder crops: flax, madder, and rape were grown, as were tobacco, hops, and turnips. These products were bought mostly by urban businesses. There was also a demand among urban consumers for dairy products such as butter and cheese, which, in the sixteenth century, had become more expensive than grain. The high prices encouraged the peasants to improve their animal husbandry techniques; for example, they began feeding their animals indoors in order to raise the milk yield of their cows.

In addition to dairy farming and cultivating industrial crops, a third sector of the Dutch economy reflected the way in which agriculture was being modernized-horticulture. In the sixteenth century, fruit and vegetables were to be found only in gardens belonging to wealthy people. This changed in the early part of the seventeenth century when horticulture became accepted as an agricultural sector. Whole villages began to cultivate fruit and vegetables. The produce was then transported by water to markets in the cities, where the consumption of fruit and vegetables was no longer restricted to the wealthy.

As the demand for agricultural produce from both consumers and industry increased, agricultural land became more valuable and people tried to work the available land more intensively and to reclaim more land from wetlands and lakes. In order to increase production on existing land, the peasants made more use of crop rotation and, in particular, began to apply animal waste to the soil regularly, rather than leaving the fertilization process up to the grazing livestock. For the first time industrial waste, such as ash from the soap-boilers, was collected in the cities and sold in the country as artificial fertilizer. The increased yield and price of land justified reclaiming and draining even more land.

The Dutch battle against the sea is legendary. Noorderkwartier in Holland, with its numerous lakes and stretches of water, was particularly suitable for land reclamation and one of the biggest projects undertaken there was the draining of the Beemster lake which began in 1608. The richest merchants in Amsterdam contributed money to reclaim a good 7,100 hectares of land. Forty-three windmills powered the drainage pumps so that they were able to lease the reclamation to farmers as early as 1612, with the investors receiving annual leasing payments at an interest rate of 17 percent. Land reclamation continued, and between 1590 and 1665, almost 100,000 hectares were reclaimed from the wetland areas of Holland, Zeeland, and Friesland. However, land reclamation decreased significantly after the middle of the seventeenth century because the price of agricultural products began to fall, making land reclamation far less profitable in the second part of the century.

Dutch agriculture was finally affected by the general agricultural crisis in Europe during the last two decades of the seventeenth century. However, what is astonishing about this is not that Dutch agriculture was affected by critical phenomena such as a decrease in sales and production, but the fact that the crisis appeared only relatively late in Dutch agriculture. In Europe as a whole, the exceptional reduction in the population and the related fall in demand for grain since the beginning of the seventeenth century had caused the price of agricultural products to fall. Dutch peasants were able to remain unaffected by this crisis for a long time because they had specialized in dairy farming industrial crops, and horticulture. However, toward the end of the seventeenth century, they too were overtaken by the general agricultural crisis.

Paragraph 1: Agriculture and fishing formed the primary sector of the economy in the Netherlands in the seventeenth century. Dutch agriculture was modernized and commercialized new crops and agricultural techniques raised levels of production so that they were in line with market demands, and cheap grain was imported annually from the Baltic region in large quantities.

Importing the grain, which would have been expensive and time consuming for the Dutch to have produced themselves, kept the price of grain low and thus stimulated individual demand for other foodstuffs and consumer goods.

1. By indicating that production was in line with market demands the author means that Dutch farmers were able to

○ exceed other European countries in agricultural production

○ produce crops mat were similar to those popular in other European countries

○ supply sufficient quantities of the agricultural products that the Dutch population wanted to buy

○ satisfy the demand for high quality agricultural products from the Baltic region

2. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.

○ Buying imported grain led to the Dutch demanding that other foodstuffs and consumer goods be imported.

○ Because the Dutch were able to import inexpensive grain, they had money available to create a demand for other food products and consumer goods.

○ Keeping the price of grain low was a primary goal of the Dutch at a time when they could not produce enough grain to provide for all their needs.

○ The demand for other foodstuffs and consumer goods forced the Dutch to import grain and other products at a time when maintaining low prices was especially important.

Paragraph 2: Apart from this, being able to give up labor-intensive grain production freed both the land and the workforce for more productive agricultural divisions.

4. According to paragraph 2, the increases demands on Dutch agriculture made by urban consumers had which of the following results?

○ Seasonal shortages of the products consumers most wanted

○ Increased production of high-quality grain products

○ Raised prices charged by peasants to urban consumers

○ Different ways of caring for dairy-producing animals

5. The word “consumption” in the passage is closest in meaning to

○ sale

○ storage

○ exportation

○ utilization

6. According to paragraph 3, the modernization of agriculture in the Netherlands was evident in all of the following ways EXCEPT:

○ The production of fruits and vegetables became a commercial venture.

○ The wealthy stopped growing fruits and vegetables in their gardens and grew flowers instead.

○ Horticultural produce was transported to city markets by water.

○ Many more people were able to afford to eat fresh fruits and vegetables.

○ Windmills became powerful enough to run drainage pumps efficiently.

○ Merchants invested large amounts of money in reclamation.

○ High interest rates discouraged people from buying land already available.

○ Reclaimed land was much more suitable for agriculture than the existing land.

Rock Art of the Australia Aborigines

Ever since European first explored Australia, people have been trying to understand the ancient rock drawings and cavings created by the Aborigines, the original inhabitants of the continent. Early in the nineteenth century, encounters with Aboriginal rock art tended to be infrequent and open to speculative interpretation, but since the late nineteenth century, awareness of the extent and variety of Australian rock art has been growing. In the latter decades of the twentieth century there were intensified efforts to understand and record the abundance of Australian rock art.

The systematic study of this art is a relatively new discipline in Australia. Over the past four decades new discoveries have steadily added to the body of knowledge. The most significant data have come from a concentration on three major questions. First, what is the age of Australian rock art? Second, what is its stylistic organization and is it possible to discern a sequence or a pattern of development between styles? Third, is it possible to interpret accurately the subject matter of ancient rock art, bring to bear all available archaeological techniques and the knowledge of present-day Aboriginal informants?

The age of Australia’s rock art is constantly being revised, and earlier datings have been proposed as the result of new discoveries. Currently, reliable scientific evidence dates the earliest creation of art on rock surfaces in Australia to somewhere between 30,000 and 50,000 years ago. This in itself is an almost incomprehensible span of generations, and one that makes Australia’s rock art the oldest continuous art tradition in the world.

Although the remarkable antiquity of Australia’s rock art is now established, the sequences and meanings of its images have been widely debated. Since the mid-1970s, a reasonably stable picture has formed of the organization of Australian rock art. In order to create a sense of structure to this picture, researchers have relied on a distinction that still underlies the forms of much indigenous visual culture—a distinction between geometric and figurative elements. Simple geometric repeated patterns—circles, concentric circles, and lines—constitute the iconography (characteristic images) of the earliest rock-art sites found across Australia. The frequency with which certain simple motifs appear in these oldest sites has led rock-art researchers to adopt a descriptive term—the Panaramitee style—a label which takes its name from the extensive rock pavements at Panaramitee North in desert South Australia, which are covered with motifs pecked into the surface. Certain features of these engravings lead to the conclusion that they are of great age—geological changes had clearly happened after the designs had been made and local Aboriginal informants, when first questioned about them, seemed to know nothing of their origins. Furthermore, the designs were covered with “desert varnish,” a glaze that develops on rock surfaces over thousands of years of exposure to the elements. The simple motifs found at Panaramitee are common to many rock-art sites across Australia. Indeed, sites with engravings of geometric shapes are also to be found on the island of Tasmania, which was separated from the mainland of the continent some 10,000 years ago.

In the 1970s when the study of Australian archaeology was in an exciting phase of development, with the great antiquity of rock art becoming clear. Lesley Maynard, the archaeologist who coined the phrase “Panaramitee style,” suggested that a sequence could be determined for Australian rock art, in which a geometric style gave way to a simple figurative style (outlines of figures and animals), followed by a range of complex figurative styles that, unlike the pan-Australian geometric tradition tended to much greater regional diversity. While accepting that this sequence fits the archaeological profile of those sites, which were occupied continuously over many thousands of years a number of writers have warned that the underlying assumption of such a sequence—a development from the simple and the geometric to the complex and naturalistic—obscures the cultural continuities in Aboriginal Australia, in which geometric symbolism remains fundamentally important. In this context the simplicity of a geometric motif may be more apparent than real. Motifs of seeming simplicity can encode complex meanings in Aboriginal Australia. And has not twentieth-century art shown that naturalism does not necessarily follow abstraction in some kind of predetermine sequence?

Certain features of these engravings lead to the conclusion that they are of great age—geological changes had clearly happened after the designs had been made and local Aboriginal informants, when first questioned about them, seemed to know nothing of their origins. Furthermore, the designs were covered with “desert varnish,” a glaze that develops on rock surfaces over thousands of years of exposure to the elements. The simple motifs found at Panaramitee are common to many rock-art sites across Australia. Indeed, sites with engravings of geometric shapes are also to be found on the island of Tasmania, which was separated from the mainland of the continent some 10,000 years ago.

6. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave ways or leave out essential information

○ The oldest rock art sites have simpler motifs than the best known sites of Panaramitee North.

○ Because motifs primarily associated with the Panaramitee region are common in the oldest sites the term Panaramitee style has become the general term for rock art of this type.

○ Because the Panaramitee style is so common in the older sites, researchers have described it most extensively.

○ The motifs carved in the rocky surface of the Panaramitee region make up the oldest form of rock art discovered in Australia.

7. According to paragraph 4, researchers have organized and structured Australian rock art by distinguishing between which of the following?

○ Images found at Panaramitee North and images found in other parts of Australia

○ Images found in a particular type of rock layer and images found in other types of rock layers

○ Images that have geometric elements and images that have figurative elements

○ Images that are typically found and image that are rarely found

8. According to paragraph 4, all of the following are signs of the great age of the Panaramitee engravings EXCEPT:

○ The engravings consisted of simple animal drawings.

○ The engravings were covered with a layer of a substance known as “desert varnish”.

○ Local Aborigines who were asked knew nothing about the origin of the engravings.来源

○ Geologic changes had occurred after the engravings were made.

9. Why does the author include information about Tasmania in paragraph 4?

○ To provide evidence that the Panaramitee style is widespread and of great age

○ To prove that Aboriginal Australians could not have made the carvings in Tasmania

○ To indicate how researchers have determined how long ago Tasmania separated from the mainland

○ To illustrate the importance of geometric rock art to tourism in Tasmania

Paragraph 5: In the 1970s when the study of Australian archaeology was in an exciting phase of development, with the great antiquity of rock art becoming clear. Lesley Maynard, the archaeologist who coined the phrase “Panaramitee style,” suggested that a sequence could be determined for Australian rock art, in which a geometric style gave way to a simple figurative style (outlines of figures and animals), followed by a range of complex figurative styles that, unlike the pan-Australian geometric tradition tended to much greater regional diversity. While accepting that this sequence fits the archaeological profile of those sites, which were occupied continuously over many thousands of years a number of writers have warned that the underlying assumption of such a sequence—a development from the simple and the geometric to the complex and naturalistic—obscures the cultural continuities in Aboriginal Australia, in which geometric symbolism remains fundamentally important. In this context the simplicity of a geometric motif may be more apparent than real. Motifs of seeming simplicity can encode complex meanings in Aboriginal Australia. And has not twentieth-century art shown that naturalism does not necessarily follow abstraction in some kind of predetermine sequence?

10. According to paragraph 5, the complex figurative style differs from the geometric style in that the complex figurative style

○ varies significantly from region to region

○ is more meaningful

○ appears on only a few types of rocks

○ has changed little overtime

11. According to paragraph 5, Lesley Maynard made which of the following suggestions about Australian rock art?

○ There were a pattern of human figures being represented in a more complex style than animal figures.

○ Australian archaeology should concentrate on determining the sequence of styles that led up to the Panaramitee style.

○ The great antiquity of Australian rock art would probably make it impossible to determine the ages of the various styles found in rock art.

○ The geometric style of Australian rock art was replaced by increasingly complex figurative styles.

12. In paragraph 5, the author indicates that twentieth century art has shown that naturalism does not necessarily follow abstraction in some kind of predetermined sequence in order to

○ emphasize that it may not be possible to determine what the figures in ancient rock art represent

○ suggest a reply to those who have questioned Maynard’s interpretation of the sequence of Australian rock art

○ provide a counterexample to Maynard’s interpretation of the sequence of Australian rock art

○ indicate that twentieth century art is more advanced than ancient rock art

Paragraph 2: The systematic study of this art is a relatively new discipline in Australia. Over the past four decades new discoveries have steadily added to the body of knowledge. The most significant data have come from a concentration on three major questions. First, what is the age of Australian rock art? Second, what is its stylistic organization and is it possible to discern a sequence or a pattern of development between styles? Third, is it possible to interpret accurately the subject matter of ancient rock art, bring to bear all available archaeological techniques and the knowledge of present-day Aboriginal informants? ■

Paragraph 3: The age of Australia’s rock art is constantly being revised, and earlier datings have been proposed as the result of new discoveries. ■Currently, reliable scientific evidence dates the earliest creation of art on rock surfaces in Australia to somewhere between 30,000 and 50,000 years ago. ■This in itself is an almost incomprehensible span of generations, and one that makes Australia’s rock art the oldest continuous art tradition in the world. ■

Answer Choices

○ Late nineteenth century studies of Aboriginal rock art railed to recognize that a variety of styles existed.

○ The extreme age of the earliest Aboriginal rock art has been established but the interpretation of rock art images is still debated.

○ In determining the way in which Australian rock art was organized, archaeologists have made little distinction between geometric and figurative elements.

○ Older examples of rock art consist of simple, repeated geometric patterns while later rock art includes figures and animals.

○ Aboriginal informants were able to explain the meanings of ancient rock art symbols.
