7、总题数:1,分数:1.00)Given that 8 percent of food crops grows faster on farms using groundwater than the aquifers are replenished, and many large rivers are so heavily diverted that they do not reach the sea for much of the year, researchers believe freshwater sources-underground aquifers and rivers-are st
8、ressed. Better management of soil and water and creative cropping patterns can boost production from rainfall-watered cropland, but the heaviest burden will fall on irrigated land. At present, most farmers irrigate their crops by channeling water down their fields in parallel furrows. One alternativ
9、e, drip systems, enables farmers to deliver water directly to the plants roots drop by drop, nearly eliminating waste by distributing water at low pressure through a network of perforated plastic tubing installed on or below the surface of the soil, where it then emerges through small holes at a slo
10、w but steady pace. Because the plants enjoy an ideal moisture environment, drip irrigation usually offers the added bonus of higher crop yields. Another alternative, sprinklers, can perform almost as well as drip methods when designed properly, but traditional high-pressure irrigation sprinklers spr
11、ay water high into the air to cover as large a land area as possible, and the more time the water spends in the air, the more of it evaporates before use. Despite the payoffs, the higher costs of these technologies relative to simple flooding methods have been a barrier to their spread, and so has t
12、he prevalence of national water policies that discourage rather than foster efficient water use. Many governments have set very low prices for publicly supplied irrigation, leaving farmers with little motivation to invest in ways to conserve water or to improve efficiency and most authorities have a
13、lso failed to regulate groundwater pumping, even in regions where aquifers are over-tapped. Therefore, farmers might be inclined to conserve their own water supplies if they could profit from selling the surplus, but this practice is often discouraged. Efforts aside from irrigation technologies are
14、also conducive to the reduction of agricultural demand for water; for instance, measurements of climate factors such as temperature and precipitation can be fed into a computer that calculates how much water a typical plant is consuming, and farmers can use this figure to determine, quite accurately
15、, when and how much to irrigate their particular crops throughout the growing season. But the most effective, if unlikely way, to do more with less water is to reconfigure our diets, especially the typical North American diet, which, with its large share of animal products, requires twice as much wa
16、ter as diets common in many Asian and some European countries. Eating lower on the food chain could allow the same volume of water to feed two Americans instead of one, and despite the resultant loss of nutrition, this may be the only recourse for countries serious about reducing their aquifer strai
17、n. (分数:0.98)(1).The primary purpose of the passage is to -|_|-.(分数:0.14)A.expose the fragile ecological conditions which modern irrigation technologies must ameliorateB.argue that new irrigation technologies would ultimately be less efficient than a reconfiguration of the North American dietC.argue
18、that efficient water-use is dependent upon a mixture of various modern methodsD.provide an overall view of possible methods for lessening the strain on sources of freshwaterE.describe the cycle by which aquifers are depleted and then replenished through technology(2).The passage implies that the str
19、ain on freshwater aquifers caused by poor irrigation patterns may be reduced by all of the following methods EXCEPT -|_|-.(分数:0.14)A.Government compensation programs for surplusB.Climate studyC.Soil managementD.Drip irrigationE.Changes in patterns of food consumption(3).Most nearly parallel, in its
20、fundamental approach to the drip system solution described in the passage would be a machine designed to -|_|-.(分数:0.14)A.save electricity by converting unused sunlight into power through the use of photocellsB.waste less electricity by insulating and reducing resistance in the conduits of the power
21、 gridC.increase electrical efficiency by requiring consumers to use appliances that rely on less electricityD.create a more reliable power grid by supplying electricity from a wider range of power plantsE.reduce the electricity necessary to powering a city by encouraging denser population growth(4).
22、It can be inferred from the passage that low-pressure sprinklers would be more preferable to high-pressure models for which of the following reasons?(分数:0.14)A.The surplus generated by low-pressure systems can be sold, lessening overall water strain on a region.B.Low-pressure systems deliver water d
23、irectly to root systems, resulting in higher crop yields.C.A lower cost is associated with low-pressure systems than with high-pressure systems, which are generally more expensive.D.Lower-pressure systems deliver water in such a way that evaporation rates are diminished, resulting in greater efficie
24、ncy.E.Crops watered by lower-pressure systems generally contain higher nutrients, reducing overall food consumption levels.(5).Which of the following can be inferred from the passage concerning the relationship between traditional irrigation methods and modern ones?(分数:0.14)A.Traditional irrigation
