Most fungi, for Line example, yield single-celled spores, which, through wind distribution, can surviv

Other types of bacteria produce a special type of spore called an endospore, capable of withstanding such extremes as boiling and freezing temperatures, and even ultraviolet radiation.Though research results r

29、ocessEsuggest which methods are effective for killing endospores at which are not 14.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, resear

30、chers believe freshwater sources-underground aquifers and rivers-are stressed. 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

31、 channeling water down their fields in parallel furrows.One alternative, 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 s

32、urface of the soil, where it then emerges through small holes at a slow 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 desi

33、gned properly, but traditional high-pressure irrigation sprinklers spray 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 simp

34、le flooding methods have been a barrier to their spread, and so has the 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 t

35、o conserve water or to improve efficiency and most authorities have also 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

36、is often discouraged.Efforts aside from irrigation technologies are 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 consu

37、ming, and farmers can use this figure to determine, quite accurately, 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

38、, with its large share of animal products, requires twice as much water 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 on

39、ly recourse for countries serious about reducing their aquifer strain.The primary purpose of the passage is to_.Aexpose the fragile ecological conditions which modern irrigation technologies must ameliorateBargue that new irrigation technologies would ultimately be less efficient than a reconfigurat

40、ion of the North American dietCargue that efficient water-use is dependent upon a mixture of various modern methodsDprovide an overall view of possible methods for lessening the strain on sources of freshwaterEdescribe the cycle by which aquifers are depleted and then replenished through technology

41、15.Many microorganisms survive such environmental stresses as heat, cold and desiccation not by rapid rates of mitosis, but by producing specialized cells designed to persist in a dormant state in hostile environments. Most fungi, for Line example, yield single-celled spores, which, through wind dis

43、gh research results remain tentative, several factors may protect endospores from environmental stress: they have a low water content, unusual proteins and a tough spore coat absent in mature bacterial cells.

44、canning at boiling temperatures, we know that these spores survive the heat and sprout in the food, and as a result, the bacteria generate the botulism toxin that can lead to food poisoningproof of their magnificent resilience.The passage mentions all of the following as environmental stresses that

45、can be survived by microorganisms that practice cellular dormancy EXCEPT_.ALow temperaturesBUltraviolet radiationCAcidic environmentsDHigh temperaturesEDrying processes 16.Given that 8 percent of food crops grows faster on farms using groundwater than the aquifers are replenished, and many large riv
