阅读补充:碰到一篇是讲technology, labor cost, productivity,然后讲到performing arts...另外还记了2个关键字chronic gap & 45 min....搜到原文,在附件里,请查收。有一题考到了那个四十五分钟和chronic gap。。。连题目我都没读懂。。。有空看看。。。。

想问一下,是这几段话吗?
For Baumol, the amount of labor necessaryto produce a typical manufactured good has constantly declined because ofproductivity gains brought about by new technology, increasing capital stock, abetter-educated labor force, and economies of scale. Meanwhile, productivity inthe live performing arts has remained relatively unchanged, for while, asBaumol himself puts it, productivity gains have created ways to reduce thelabor needed to produce a car, no one has yet devised ways of reducing thework-hours needed to perform a 45-minute Schubert quartet.  Baumol's "somber conclusions" areclear: The arts cannot match the productivity gains of the economy as a whole,thus creating the chronic income gap between performing organizations' costsand their earnings.  
Thirty years after its publication,Baumol's insight remains highly influential, directing empirical studies,theoretical analysis, and animating debates in an era of federal budgetconstraints. Baumol himself has advocated subsidies, tax laws, and otherincentives for giving to the arts, citing as key arguments the cost disease aswell as the social benefits of the arts.
For all its merits, the empirical evidenceof Baumol's cost disease is not conclusive. For example, in a review of theprincipal directions of cultural economics over the past thirty years, DavidThrosby claims that empirical analyses of the cost disease have found "littleevidence of differential rates of inflation" in the arts relative to therest of the economy. The empirical studies that Throsby cites also find thatlower wage increases, changes in the repertoire, and increased demand anddonations have generally countered the expanding deficit in the performingarts.
On the other hand, in a recent empiricalstudy of 25 U.S. orchestras over a 21-year period (1972 to 1992), MarianneFelton observes that orchestras are indeed subject to the cost disease. Shenotes, however, that her results "also reveal that productivity increasesare possible." She points out the 26 percent increase in performances from1986 to 1992. Contrary to expectations, orchestra productivity growth in thesample actually outstripped that of the manufacturing sector during this period(307).
Assuch, we can only conclude that it is still far from certain that theperforming arts are indeed subject to the cost disease and the phenomenonremains in need of more empirical verification.

第一段就好。

你可以再搜一下chronic gap所在的段落,加上就差不多了

PUBLIC RELEASE: 18-SEP-2006
Droughts and reservoirs: Finding storage space underground
GEOLOGICAL SOCIETY OF AMERICA
Boulder, CO Odd as it sounds, in some places the smartest way to safeguard the water supply is to let it drain out of the reservoirs and soak into the ground. That's what been discovered in local water shortages in Kansas, Oklahoma, and New Mexico - all of which could be microcosms of water shortage issues looming throughout the Western U.S.

In these three cases - Cedar Bluff Reservoir (Hays, KS), Optima Lake, (Guymon, OK), and Storrie Lake (Las Vegas, NM) - water losses from evaporation are so high that they can accelerate water supply emergencies for farms and cities, explains Tom Brikowski, a professor of hydrology at the University of Texas at Dallas. Brikowski and Wayland Anderson, a Denver engineer, are presenting their work at the Geological Society of America conference on Managing Drought and Water Scarcity in Vulnerable Environments: Creating a Roadmap for Change. The meeting takes place 18-20 September at the Radisson Hotel and Conference Center in Longmont, Colorado.

In the case of the City of Hays, the trouble starts 20 miles upstream at the Cedar Bluff Reservoir. Because of changes in farming practices, the reservoir gets only half the inflowing water it did when built in 1949. It now loses 75 percent of its inflowing water to evaporation. As a result, water losses most years now equal or exceed inflows. Reservoir releases were cut in 1979.
"You get to the point where you can't afford to lose that much water," said Brikowski, "and your only other alternative is to store it underground."

But how do you do that? In the case of Hays, nature had already provided for underground storage in the form of the Smoky Hill River aquifer. The aquifer has provided half the city's water supply for decades. Since the building of the Cedar Bluff reservoir, however, stream flow on top of it has dropped by 50 percent. That stream water recharged the wells, which, in turn, kept alive the town of Hays, Brikowski explains.

第二段提到附近城鎮的underwater和wells也受影響  每次乾旱後wells水位都回覆的很慢   找了experts來針對城市供水系統進行3D建模


At the behest of the City of Hays, Brikowski and Anderson created a detailed three-dimensional model of the sandy, gravelly ("alluvial") ground beneath the Smokey Hill River. Anderson analyzed the water balance of the reservoir. Next they simulated what had happened to the dropping water table, how much groundwater the aquifer could store, and how long a drought it could endure.

.讲Hay这个地方的水库reservoir,因为蒸发失去了很多的水,导致水库的水位下降,然后一个xx专家就要解决这个问题,带人来研究,做了一个3d模型进行分析,认为需要换一个水的来源,利用aquifer蓄水,采用这个方法的话需要大量release水库里的水,来使aquifer有充足的水,这样就不会因为蒸发和一些别的问题缺水了


"It's a clear case that the shut off of water (by the reservoir) limited how much water Hays could pump," said Brikowski. It also showed that by releasing water from that same reservoir they could kill two birds with one stone: recharge the aquifer and reduce the evaporation loss rate. According to Brikowski, "It was pretty hard to argue with the conclusion."

They also found that by releasing reservoir water to recharge the Smoky Hill River aquifer, users could survive even the worst recorded drought with full production from municipal wells.
"I think the City as a whole was quite happy," said Brikowski. By getting a better understanding of their water, the city can now avert seasonal water emergencies and no longer have to consider building hundreds of miles of pipeline to get water from other river basins.

This story could replay in other places as well - especially where reservoirs are getting less inflow due to changing water uses or climate change.

There's the city of Las Vegas, NM, only months away from evacuations this year after lack of snow over the winter left streams dry. It was only the annual monsoon season that saved them this year, said Brikowski. The water crisis is becoming an almost annual event as winter snow packs shrink and melt sooner each spring, probably as a consequence of global warming.

"More efficient storage, perhaps in alluvial aquifers, represents the only real hope for a solution," Brikowski said.

The same may eventually be the case for most of California, which relies heavily on the melting of snow pack high in the Sierra Nevada to feed streams and rivers through the summer. Global warming is expected to raise the snowline on those mountains and has already pushed spring earlier in the year. This means there is generally less snowmelt and it may not last the whole summer.

The Optima Reservoir of the Oklahoma Panhandle is an extreme example. A dry lake, it loses 100 percent of its inflowing water to evaporation. Converting to subsurface storage may be the only way to store water.

"It's not that in any of these places they've done anything wrong," Brikowski said. Rather, situations change and water management has to keep up to avoid supply problems. Underground storage, he said, is something to add to the water management toolbox.
