8、er 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 stressed. Better management of soil and water and creative cropping patterns can boost p

9、roduction 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 alternative, drip systems, enables farmers to deliver water directly to the plants roots drop by

10、 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 slow but steady pace. Because the plants enjoy an ideal moisture environment, drip irriga

11、tion 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 spray water high into the air to cover as large a land area as possible, and the more tim

12、e 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 the prevalence of national water policies that discourage rather than foster efficient

13、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 also failed to regulate groundwater pumping, even in regions where aquifers are over-ta

14、pped. 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 also conducive to the reduction of agricultural demand for water; for instance, measur

15、ements 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, when and how much to irrigate their particular crops throughout the growing season.

16、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 water as diets common in many Asian and some European countries. Eating lower on the foo

17、d 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 strain. （分数：0.98）(1).The primary purpose of the passage is to -|_|-.（分数：0.14）A.expose the f

24、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 efficiency.E.Crops watered by lower-pressure systems generally contain higher nutrients, redu

26、endent on technology.B.Traditional methods may best be used in areas where the technological knowledge necessary for using modern techniques is limited.C.Modern methods, unlike traditional ones, can only help land whose primary water source comes from irrigation, not rainfall.D.Modern methods rely m

27、ore heavily upon groundwater tapping, which itself depletes the aquifer.E.Traditional methods can be performed without the tedious and difficult calculation of climate factors.(6).According to the passage, the main disadvantage with reconfiguring diet to lessen water usage is -|_|-.（分数：0.14）A.most N

31、niversally accessible, but unnecessaryMany 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-cel

32、led spores, which, through wind distribution, can survive for long periods of time before germinating and sprouting fungal filaments of their own. Other types of bacteria produce a special type of spore called an endospore, capable of withstanding such extremes as boiling and freezing temperatures,

33、and even ultraviolet radiation. Though 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. When garden fruits and vegetables, which may contain bo

34、tulism endospores, are preserved by 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. （分数：-1.00）(1).The authors primary pu
