DESERTIFICATION Desertification is the degradation of once-productive land into unproductive or poorly productive land. Since the first great urban-agricultural centers in Mesopotamia nearly 6,000 years ago, human activity has had a destructive impact on soil quality, leading to gradual desertification in virtually every area of the world. It is a common misconception that desertification is caused by droughts. Although drought does make land more vulnerable, well-managed land can survive droughts and recover, even in arid regions. Another mistaken belief is that the process occurs only along the edges of deserts. In fact, it may take place in any arid or semiarid region, especially where poor land management is practiced. Most vulnerable, however, are the transitional zones between deserts and arable HOC24.VN 5 land; wherever human activity leads to land abuse in these fragile marginal areas, soil destruction is inevitable. [1] Agriculture and overgrazing are the two major sources of desertification. [2] Large- scale farming requires extensive irrigation, which ultimately destroys lands by depleting its nutrients and leaching minerals into the topsoil. [3] Grazing is especially destructive to land because, in addition to depleting cover vegetation, herds of grazing mammals also trample the fine organic particles of the topsoil, leading to soil compaction and erosion. [4] It takes about 500 years for the earth to build up 3 centimeters of topsoil. However, cattle ranching and agriculture can deplete as much as 2 to 3 centimeters of topsoil every 25 years - 60 to 80 times faster than it can be replaced by nature. Salination is a type of land degradation that involves an increase in the salt content of the soil. This usually occurs as a result of improper irrigation practices. The greatest Mesopotamian empires- Sumer, Akkad and Babylon- were built on the surplus of the enormously productive soil of the ancient Tigris- Euphrates alluvial plain. After nearly a thousand years of intensive cultivation, land quality was in evident decline. In response, around 2800 BC the Sumerians began digging the huge Tigris-Euphrates canal system to irrigate the exhausted soil. A temporary gain in crop yield was achieved in this way, but over-irrigation was to have serious and unforeseen consequences. From as early as 2400 BC we find Sumerian documents referring to salinization as a soil problem. It is believed that the fall of the Akkadian Empire around 2150 BC may have been due to a catastrophic failure in land productivity; the soil was literally turned into salt. Even today, four thousand years later, vast tracks of salinized land between the Tigris and Euphrates rivers still resemble rock-hard fields of snow. Soil erosion is another form of desertification. It is a self-reinforcing process; once the cycle of degradation begins, conditions are set for continual deterioration. As the vegetative cover begins to disappear, soil becomes more vulnerable to raindrop impact. Water runs off instead of soaking in to provide moisture for plans. This further diminishes plan cover by leaching away nutrients from the soil. As soil quality declines and runoff is increased, floods become more frequent and more severe. Flooding washes away topsoil, the thin, rich, uppermost layer of the earth’s soil, and leaves finer underlying particles more vulnerable to wind erosion. Topsoil contains the earth’s greatest concentration of organic matter and microorganisms, and is where most of the earth’s land-based biological activity occurs. Without this fragile coat of nutrient-laden material, plan life cannot exist. An extreme case of its erosion is found in the Sahel, a transitional zone between the Sahara Desert and the tropical African rain forests; home to some 56 million people. Overpopulation and overgrazing have opened the hyperarid land to wind erosion, which is stripping away the protective margin of the Sahel, and causing the desert to grow at an HOC24.VN 6 alarming rate. Between 1950 and 1975, the Sahara Desert spread 100 kilometers southward through the Sahel. Question 36: Which of the following statement is true about desertification? A. It has a history as long as that of civilization. B. It was just as serious in the past as it is today. C. It is a fairy recent problem. D. Ancient societies managed the problem well. Question 37: The word “arable” in paragraph 2 is closet in meaning to _____. A. cultivate B. dry C. settled D. populated Question 38: According to the passage, many people’s understanding of desertification is incorrect because _____. A. they do not think of of it as a serious problem B. they see it as being reversible C. they do not see it as being caused by human activity D. they think of it as a very slow process Question 39: According to the passage, agriculture furthers desertification through which of the following activities A. The repetitive planting of the same crop B. Irrigation C. The stripping away of native vegetation D. Over fertilization Question 40: The word “degradation” in paragraph 4 is closet in meaning to _____.

(1) Iron production was revolutionized in the early eighteenth century when coke was first used instead of charcoal for refining iron ore. Previously the poor quality of the iron had restricted its use in architecture to items such as chains and tie bars for supporting arches, vaults, and walls. With the improvement in refining ore, it was now possible to make cast-iron beams, columns, and girders. During the nineteenth century further advances were made, notably Bessemer’s process for converting iron into steel, which made the material more commercially viable. HOC24.VN 7 (2) Iron was rapidly adopted for the construction of bridges, because its strength was far greater than that of stone or timber, but its use in the architecture of buildings developed more slowly. By 1800 a complete internal iron skeleton for buildings had been developed in industrial architecture replacing traditional timber beams, but it generally remained concealed. Apart from its low cost, the appeal of iron as a building material lay in its strength, its resistance to fire, and its potential to span vast areas. As a result, iron became increasingly popular as a structural material for more traditional styles of architecture during the nineteenth century, but it was invariably concealed. (3) Significantly, the use of exposed iron occurred mainly in the new building types spawned by the Industrial Revolution: in factories, warehouses, commercial offices, exhibition hall, and railroad stations, where its practical advantages far outweighed its lack of status. Designers of the railroad stations of the new age explored the potential of iron, covering huge areas with spans that surpassed the great vaults of medieval churches and cathedrals. Paxton’s Crystal Palace, designed to house the Great Exhibition of 1851, covered an area of 1.848 feet by 408 feet in prefabricated units of glass set in iron frames. The Paris Exhibition of 1889 included both the widest span and the greatest height achieved so far with the Halle Des Machines, spanning 362 feet, and the Eiffel Tower 1,000 feet high. However, these achievements were mocked by the artistic elite of Paris as expensive and ugly follies. Iron, despite its structural advantages, had little aesthetic status. The use of an exposed iron structure in the more traditional styles of architecture was slower to develop. Question 43: What does the passage mainly discuss? A. Advances in iron processing in the eighteenth and nineteenth centuries. B. The effects of the Industrial Revolution on traditional architectural styles. C. Advantages of stone and timber over steel as a building material. D. The evolution of the use of iron in architecture during the 1800’s. Question 44: According to the passage, iron was NOT used for beams, columns, and girders prior to the early eighteenth century because _____. A. all available iron was needed for other purposes B. limited mining capability made iron too expensive C. iron was considered too valuable for use in public buildings D. the use of charcoal for refining ore produced poor quality iron Question 45: Iron replaced stone and timber in the building of bridges because iron was considered _____. A. more beautiful B. new and modern C. much stronger D. easier to transport Question 46: The word “it” in paragraph 2 refers to_____. A. industrial architecture B. internal iron skeleton C. stone D. strength HOC24.VN 8 Question 47: The word “surpassed” is closest in meaning to _____. A. imitated B. exceeded C. approached D. included Question 48: According to paragraph 3, the architectural significance of the Halle Des Machines was its _____. A. wide span B. great height C. unequaled beauty D. prefabricated unites of glass Question 49: How did the artistic elite mentioned in the passage react to the buildings at the Paris Exhibition? A. They tried to copy them. B. They ridiculed them. C. They praised them. D. They refused to pay to see them. Question 50: It can be inferred that the delayed use of exposed iron structures in traditional styles of architecture is best explained by the _____. A. impracticality of using iron for small, noncommercial buildings B. association of iron architecture with the problems of the Industrial Revolution C. general belief that iron offered less resistance to fire and harsh weather than traditional materials D. general perception that iron structures were not aesthetically pleasing
