[单项选择] 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 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 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 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 irrigation usually offers
A. wholly effective, but typically ignored

[简答题]In many developing countries, software piracy has become pandemic. According to Software Publishers Association, 95% of the software in Pakistan is pirated, 89% in Brazil, 88% in Malaysia and 82% in Mexico. (1) Hundreds of tiny gizmo shops in the mazelike streets of Seoul’s Yongsan electronics market offer brandname U.S. made programs for a programer for a fraction of the list price, including Lotus 1-2-3 for $7.50 (suggested retail: $368). New Delhi’s largest pirate outlet is a backroom operation that offers customers a catalog of nearly 400 titles and facilities for making copies for as little as $ 4 a disk ($2.50 for customers who bring their own floppies).
How to combat this rampant piracy (2) The publishers’ first approach was to control it through technical means—by putting codes in their programs that prevented users from copying them.
This strategy worked for a while, or at least until determined pirates found ways to get around it.
