问答题{{U}}Before 1965 many scientists pictured the circulation of the ocean's water mass as consisting of large, slow-moving currents, such as the Gulf Stream.{{/U}} {{U}}That view{{/U}}, based on 100 years of observations made around the globe, {{U}}produced only a rough approximation of the true circulation.{{/U}} But in the 1950's and the 1960's, {{U}}researchers began to employ newly developed techniques and equipment,{{/U}} including subsurface floats that move with ocean currents and emit identification signals, and ocean-current meters that record data for months at fixed locations in the ocean. {{U}}These instruments disclosed an unexpected level of variability in the deep ocean.{{/U}} Rather than being characterized by smooth, large-scale currents that change seasonally (if at all), the seas are dominated by what oceanographers call mesoscale fields: fluctuating, energetic flows whose velocity can reach ten times the mean velocity of the major currents.
Mesoscale phenomena—the oceanic analogue of weather systems—often extend to distances of 100 kilometers and persist for 100 days (weather systems generally extend about 1,000 kilometers and last 3 to 5 days in any given area). {{U}}More than 90 percent of the kinetic energy of the entire ocean may be accounted for by mesoscale variability rather than by large-scale currents. Mesoscale phenomena may, in fact, play a significant role in oceanic mixing, air-sea interactions, and occasional—but far-reaching—climatic events such as E1 Nino,{{/U}} the atmospheric-oceanic disturbance in the equatorial Pacific that affects global weather patterns.
{{U}}Unfortunately, it is not feasible to use conventional techniques to measure mesoscale fields.{{/U}} To measure them properly, monitoring equipment would have to be laid out on a grid at intervals of at most 50 kilometers, with sensors at each grid point lowered deep in the ocean and kept there for many months. Because using these techniques would be prohibitively expensive and time-consuming, {{U}}it was proposed in 1979 that tomography be adapted to measuring the physical properties of the ocean.{{/U}} In medical tomography x-rays map the human body's density variations (and hence internal organs); the information from the x-rays, transmitted through the body along many different paths, is recombined to form three-dimensional images of the body's interior. It is primarily this multiplicative increase in data obtained from the multipath transmission of signals that accounts for oceanographers' attraction to tomography: {{U}}it allows the measurement of vast areas with relatively few instruments.{{/U}} Researchers reasoned that low-frequency sound waves, because they are so well described mathematically and because even small perturbations in emitted sound waves can be detected, could be transmitted through the ocean over many different paths and that the properties of the ocean's interior—its temperature, salinity, density, and speed of currents—could be deduced on the basis of how the ocean altered the signals. Their initial trials were highly successful, and ocean acoustic tomography was born.
问答题Task 2: Argument Analysis Directions:
In 30 minutes, prepare a critical analysis of an argument expressed in a short
paragraph. You may not offer an analysis of any other argument. Write your essay
on the lined page that follows. As you critique the argument,
think about the author's underlying assumptions. Ask yourself whether any of
them are questionable. Also evaluate any evidence the author brings up. Ask
yourself whether it actually supports the author's conclusion.
In your analysis, you may suggest additional kinds of evidence to reinforce the
author's argument. You may also suggest methods to refute the argument, or
additional data that might be useful to you as you assess the soundness of the
argument. You may not, however, present your personal views on the topic. Your
job is to analyze the elements of an argument, not to support or contradict that
argument. Faculty members from various institutions will judge
your essay, assessing it on the basis of your skill in the following
areas: · Identification and assessment of the argument's main
elements · Organization and articulation of your
thoughts · Use of relevant examples and arguments to support
your case · Handling of the mechanics of standard written
English Topic The following appeared in a
petition presented by Classen University students to the school's
administration. The purpose of higher education is to prepare
students for the future, but Classen students are at a serious disadvantage in
the competition for post-college employment due to the University's burden- some
breadth requirements. Classen's job placement rate is substantially lower than
placement rates of many top-ranked schools. Classen students would be more
attractive to employers if they had more time to take advanced courses in their
specialty, rather than being required to spend fifteen percent of their time at
Classen taking courses outside of their subject area. We demand, therefore, that
the University abandon or drastically cut back on its breadth requirements.
问答题Warm-blooded animals have elaborate physiological controls to maintain constant body temperature (in humans, 37℃). Why then during sickness should temperature rise, apparently increasing stress on the infected organism? It has long been known that the level of serum iron in animals falls during infection. Garibaldi first suggested a relationship between fever and iron. He found that microbial synthesis of siderophores—substances that bind iron—in bacteria of the genus Salmonella declined at environmental temperatures above 37℃ and stopped at 40.3℃. Thus, fever would make it more difficult for an infecting bacterium to acquire iron and thus to multiply. Cold-blooded animals were used to test this hypothesis because their body temperature can be controlled in the laboratory. Kluger reported that of iguanas infected with the potentially lethal bacterium A.hydrophilia, more survived at temperatures of 42℃ than at 37℃, even though healthy animals prefer the lower temperature. When animals at 42℃ were injected with an iron solution, however, mortality rates increased significantly. Research to determine whether similar phenomena occur in warm-blooded animals is sorely needed.
问答题{{U}}Hydrogeology is a science dealing with the properties, distribution, and circulation of water on the surface of the land, in the soil and underlying rocks, and in the atmosphere.{{/U}} The hydrologic cycle, a major topic in this science, is the complete cycle of phenomena through which water passes, beginning as atmospheric water vapor, passing into liquid and solid form as precipitation, thence along and into the ground surface, and finally again returning to the form of atmospheric water vapor by means of evaporation and transpiration.
{{U}}The term "geohydrology" is sometimes erroneously used as a synonym for "hydrogeology".{{/U}} Geohydrology is concerned with underground water. There are many formations that contain water but are not part of the hydrologic cycle because of geologic changes that have isolated them underground. These systems are properly termed geohydrologic but not hydrogeologic. Only when a system possesses natural or artificial boundaries that associate the water within it with the hydrologic cycle may the entire system properly be termed hydrogeologic.

As concerns over man's impact on the global
environment increase, many interesting innovations are being considered. For
example, "green roofs" - plant-filled roof top gardens - are one substantial way
to confront the country's ecological problems, and there seems to be very little
in the way of a downside. For one thing, a green roof acts as a sponge for
rainwater, absorbing the majority of water from a typical rainstorm. Only three
to five inches of soil for a green roof is sufficient for this to occur, which
keeps the weight of the roof to a minimum. Because the plantings on the roof
absorb the rainwater, drainage and sewage systems have a decreased volume of
water pumping through them, keeping these systems from becoming over-stressed.
And while, the soil and plants are absorbing rainwater, they are also taking in
pollutants for their own nourishment by storing carbon and then emitting
necessary oxygen back into the atmosphere.
For generations, Native Americans used myths and legends to explain the mysterious world around them. One such etiological myth originated with the Cherokee. According to the tale, at one time, far in the past, animals, birds, fishes, and even insects were able to communicate with one another. When humans arrived, however, life became more difficult because the creatures" habitats began to shrink. In order to protect themselves, the creatures decided to introduce disease to humans. The plant world, however, took sympathy upon the Cherokee and so provided a remedy for each of the diseases created by the creatures. It was because of this, says the legend, that the Cherokee turned to plants for antidotes and medicines for illness.
