◆1021 GRE阅读第一篇命中：Maya Water 马雅的水(本篇英文原题)
Recent studies of ancient Maya water management have found that the urban
architecture of some cities was used to divert rainfall runoff into gravity-fed
systems of interconnected reservoirs. In the central and southern Maya Lowlands,
this kind of water control was necessary to support large populations throughout
the year due to the scarcity of perennial surface water and the seasonal
availability of rainfall. Some scholars argue that the concentration of water
within the urban core of these sites provided a centralized source of political
authority for Maya elites based largely on controlled water access. Such an
argument is plausible; however, it is less useful for understanding the
sociopolitical implications of water use and control in other, water-rich parts
of the Maya region.
帮同学奉上原题与正解：
1. The author of the passage implies which of the following about the political
import of the type of urban water management system described in the passage?
The system is not sufficient to explain the sources of centralized political
power in all parts of the Maya region
Consider each of the choices separately and select all that apply.
2. According to the passage, which of the following is true of the water
management systems in the central and southern Maya Lowlands?
They were implemented in part because of the prevailing pattern of rainfall.
They were an integral part of lowland cities' architecture.
They were needed because of insufficient resources such as ponds, rivers, and
lakes in the lowlands.
◆1021 GRE阅读第二篇命中：Antelope羚羊(本篇英文原题)
Historically, more cold-adapted antelope species originating in Eurasia have
migrated into Africa, where the climate is generally warmer, than have
warm-adapted African species into Eurasia. A likely explanation for this
involves the fact that intercontinental migrations require both a land bridge
connecting the two continents and suitable habitat both on and across that land
bridge. During periods of climatic cooling, such as the various ice ages, the
land bridge is open for a long time (because sea level remains low) and is
usable by cold-adapted species because cool habitats then extend across it. Thus
during cooling most migrants would be expected to travel toward Africa, which is
near the equator, since this is the direction dictated by habitat changes on a
cooling Earth. In contrast, when the Earth is warm, the land bridge is reduced
or gone because sea level is relatively high then. Only during the short lag
between the onset of global temperature change and sea level response can
warm-adapted species migrate from the equator toward higher latitudes.
帮同学奉上原题与正解：
1. According to the passage, which of the following is true of a Eurasia-Africa
land bridge during ice ages?
It offers suitable habitats for cold-adapted species of antelope.
2. The author of the passage implies that during the "short lag," a land bridge
between Africa and Eurasia would
Contain habitats that could sustain warm-adapted antelope species
3. According to the passage, which of the following best accounts for the
apparent bias in antelope-migration direction?
Land bridges are more likely to exist when climate change favors migration to
warmer climates than when climate change favors migration to cooler climates.

1021 GRE逻辑真题：总共一组命中真经班
◆逻辑命中真经班：Normally, seeds of Emmenathe………(本篇英文原题)
Normally, seeds of Emmenathe penduliflora stay dormant for years and germinate
only when a fire burns through their habitat. Nitrogen dioxide in the smoke
induces the seeds to germinate. Fires clear the brush, allowing germinating
seeds to receive the sunlight they need to grow. The plants mature quickly,
produce seeds, and then die. In areas with heavy automobile traffic, however,
the seed germinates in the absence of fire, with automobile exhaust supplying
the required nitrogen dioxide.
帮同学奉上原题与正解：
The information given, if accurate, most strongly supports which of the
following hypotheses?
If human intervention decreases the number of fires in the habitat of E.
Penduliflora, automobile exhaust can replicate the conditions the plant requires
in order to thrive.
