真经GRE阅读机经365篇-Passage 68
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 the 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-adapt 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 onset of global temperature change and sea level response can warm-adapted species migrate from the equator toward higher latitudes.
1.According to the passage,which of the following is true of an Eurasia-Africa land bridge during ice ages?
A.It offers suitable habitats for cold-adapted species of antelope.
B.It encourages migration from Africa to Eurasia of cold-adapted species of antelope.
C.It allows the survival of warm-adapted species of antelope that might otherwise home extinct.
D.It is more likely to exist early in an ice age than later in an ice age.
E.The habitats it offers change more quickly than do those offered by land bridges during other periods.
2.The author of the passage implies that during the“short lag”,a land bridge between Africa and Eurasia would
A.be inhabited primarily by species of antelope originating in Eurasia
B.be characterized by areas of widely varying elevation above sea level
C.be inhabited by a wide diversity of antelope species
D.contain habitats that could sustain warm-adapt antelope species
E.contain habitats similar to habitats at much higher latitudes in Eurasia
3.According to the passage,which of the following best accounts for the apparent bias in antelope-migration direction?
A.Warm-adapted antelope species are rarely able to tolerate cool habitats,whereas cold-adapted antelope species usually can tolerate warm habitats.
B.During global warming periods,land bridges,when present,lack habitats suitable for sustaining warm-adapted antelope species.
C.Under most climatic conditions,Africa offers a larger number of suitable antelope habitats than does Eurasia.
D.Many more species of antelope have originated in Eurasia than have originated in Africa.
E.Land bridges are more likely to exist when climate change favors migration to warmer climates than when climate changes favors migration to cooler climates.
真经GRE阅读机经365篇-Passage 134
An influential early view held that ecosystems contain niches for a limited number of species and that competition for resources among species—whether native or nonnative invading ones—determines ecosystems’species composition.However,factors other than competition often help explain invading species’success.For example,the American grey squirrel,often cited as a classic example of competitively superior invading species,was introduced in England in 1876 and now thrives,while the native red squirrel population has declined.Although scientists have found gray squirrels to be more efficient foragers than red ones,they also note that even before the gray squirrel’s arrival,Britain’s red squirrel populations had a periodic tendency to die out,only to be subsequently reintroduced.Furthermore,many gray squirrels are silent carriers of a disease fatal to red squirrels.
1.It can be inferred that the author of the passage mentions the efficiency with which gray squirrels forage primarily in order to
A.identify a factor that explains a certain phenomenon
B.call attention to an inconsistency in a particular theory
C.suggest that competition cannot be the factor responsible for a particular outcome
D.acknowledge a fact that appears to support a view that the author intends to qualify
E.cite evidence that is not consistent with an early influential view about species competition
2.It can be inferred that the author of the passage would be most likely to agree with which of the following statements about the“early view?”
A.It reflects a mistaken assumption about the means by which nonnative species are introduced into ecosystems.
B.Its basic premise is shown to be valid by the effect of American gray squirrels on Britain’s red squirrel population.
C.It presents a simplistic picture of the means by which species composition within ecosystems is determined.
D.It can effectively explain the formation of ecosystems that contain few species but cannot adequately account for the formation of complex ecosystems.
E.It understates the importance of competition as a factor determining species composition within ecosystems.
真经GRE阅读机经365篇-Passage 31
Scientific consensus is that humans first began to have a warming effect on Earth’s climate within the past century,after coal-burning factories,power plants,and motor vehicles began releasing carbon dioxide(CO2)and other greenhouse gases in significant quantities into the air.However,evidence suggests that human agricultural activities may have had such an effect much earlier:concentrations of CO2 started rising about 8000 years ago,even though natural trends indicate they should have been dropping;methane levels rose similarly about 3,000 years later.Without these rises,however,current temperatures in northern parts of North America and Europe would be cooler by three to four degrees Celsius-enough to inhibit agriculture-and an ice age would probably have begun several thousand years ago in northeastern Canada.
1.Which of the following best describes the function of the highlighted sentence?
A.It undermines the assumption that human activity has had a significant impact on Earth’s climate
B.It supports the assumption that Earth’s temperatures have risen appreciably over the past 100 years
C.It questions the assumption that greenhouse gases have had a warming effect on Earth's climate美国研究生留学考试
D.It challenges the assumption that human activity began to affect Earth’s climate after the advent of industrialization
E.It supports the assumption that greenhouse gases are a direct by-product of industrial activities
2.The author mentions“natural trends”most likely in order to
A.propose a possible explanation for why current temperatures in North America and Europe are not as low as they might otherwise be
B.explain why levels of methane in Earth's atmosphere began to rise approximately 5,000 years ago
C.suggest that Earth’s climate would have become even warmer without the advent of human agricultural activities
D.identify factors that may have contributed to the rise of greenhouse gases in Earth’s atmosphere approximately 8,000 years ago and again some 3,000 years later
E.support the claim that human activity may have played a role in the rise in CO2 and methane levels in the atmosphere thousands of years ago
