Passage 2

Recent studies of sediment in the North Atlantic’s deep waters reveal possible cyclical patterns in the history of Earth’s climate. The rock fragments in these sediments are too large to have been transported there by ocean currents; they must have reached their present locations by traveling in large icebergs that floated long distances from their point of origin before melting. Geologist Gerard Bond noticed that some of the sediment grains were stained with iron oxide, evidence that they originated in locales where glaciers had overrun outcrops of red sandstone. Bond’s detailed analysis of deep-water sediment cores showed changes in the mix of sediment sources over time: the proportion of these red-stained grains fluctuated back and forth from lows of 5 percent to highs of about 17 percent, and these fluctuation occurred in a nearly regular 1,500-year cycle.

Bond hypothesized that the alternating cycles might be evidence of changes in ocean-water circulation and therefore in Earth’s climate. He knew that the sources of the red-stained grains were generally close to the North Pole than were the places yielding a high proportion of “clean” grains. At certain times, apparently, more icebergs from the Arctic Ocean in the far north were traveling south well into the North Atlantic before melting and shedding their sediment.

Ocean waters are constantly moving, and water temperature is both a cause and an effect of this movement. As water cools, it becomes denser and sinks to the ocean’s bottom. During some periods, the bottom layer of the world’s oceans comes from cold, dense water sinking in the far North Atlantic. This causes the warm surface waters of the Gulf Stream to be pulled northward. Bond realized that during such periods, the influx of these warm surface waters into northern regions could cause a large proportion of the icebergs that bear red grains to melt before traveling very far into the North Atlantic. But sometimes the ocean’s dynamic changes, and waters from the Gulf Stream do not travel northward in this way. During these periods, surface waters in the North Atlantic would generally be colder, permitting icebergs bearing red-stained grains to travel farther south in the North Atlantic before melting and depositing their sediment.

The onset of the so-called Little Ice Age (1300-1860), which followed the Medieval Warm Period of the eighth through tenth centuries, may represent the most recent time that the ocean’s dynamic changed in this way. If ongoing climate-history studies support Bond’s hypothesis of 1,500-year cycles, scientists may establish a major natural rhythm in Earth’s temperatures that could then be extrapolated into the future. Because the midpoint of the Medieval Warm Period was about A.D. 850, an extension of Bond’s cycles would place the midpoint of the next warm interval in the twenty-fourth century.

1. According to the passage, which of the following is true of the rock fragments contained in the sediments studied by Bond?

A. The majority of them are composed of red sandstone.

B. They must have reached their present location over 1,500 years ago.

C. They were carried by icebergs to their present location.

D. Most of them were carried to their present location during a warm period in Earth’s climatic history.

E. They are unlikely to have been carried to their present location during the Little Ice Age.

2. In the final paragraph of the passage, the author is concerned primarily with

A. Answering a question about Earth’s climatic history

B. Pointing out a potential flaw in Bond’s hypothesis

C. Suggesting a new focus for the study of ocean sediments.

D. Tracing the general history of Earth’s climate

E. Discussing possible implications of Bond’s hypothesis

3. According to the passage, Bond hypothesized that which of the following circumstances would allow red-stained sediment grains to reach more southerly latitudes?

A. Warm waters being pulled northward from the Gulf Stream

B. Climatic conditions causing icebergs to melt relatively quickly

C. Icebergs containing a higher proportion of iron oxide than usual

D. The formation of more icebergs than usual in the far north

E. The presence of cold surface waters in the North Atlantic

4. It can be inferred from the passage that in sediment cores from North Atlantic’s deep waters, the portions that correspond to the Little Ice Age

A. differ very little in composition from the portions that correspond to the Medieval Warm Period

B. fluctuate significantly in composition between the portions corresponding to the 1300s and the portions corresponding to the 1700s

C. would be likely to contain a proportion of red-stained grains closer to 17 percent than to 5 percent.

D. show a much higher proportion of red-stained grains in cores extracted from the far north of the North Atlantic than in cores extracted from further south

E. were formed in part as a result of Gulf Stream waters having been pulled northward

Passage 1

Reviving the practice of using elements of popular music in classical composition, an approach that had been in hibernation in the United States during the 1960s, composer Philip Glass (born 1937) embraced the ethos of popular music without imitating it. Glass based two symphonies on music by rock musicians David Bowie and Brian Eno, but the symphonies’ sound is distinctively his. Popular elements do not appear out of place in Glass’s classical music, which from its early days has shared certain harmonies and rhythms with rock music. Yet this use of popular elements has not made Glass a composer of popular music. His music is not a version of popular music packaged to attract classical listeners; it is high art for listeners steeped in rock rather than the classics.

1. The passage addresses which of the following issues related to Glass’s use of popular elements in his classical compositions?

A. How it is regarded by listeners who prefer rock to the classics

B. How it has affected the commercial success of Class’s music

C. Whether it has contributed to a revival of interest among other composers in using popular elements in their compositions

D. Whether it has had a detrimental effect on Glass’s reputation as a composer of classical music

E. Whether it has caused certain of Glass’s works to be derivative in quality

2. The passage suggests that Glass’s work displays which of the following qualities?

A. A return to the use of popular music in classical compositions

B. An attempt to elevate rock music to an artistic status more closely approximating that of classical music

C. A long-standing tendency to incorporate elements from two apparently disparate musical styles

Passage 23

Saturn’s giant moon Titan is the only planetary satellite with a significant atmosphere and the only body in the solar system other than Earth that has a thick atmosphere dominated by molecular nitrogen. For a long time, the big question about Titan’s atmosphere was how it could be so thick, given that Jupiter’s moons Ganymede and Callisto, which are the same size as Titan, have none. The conditions for acquiring and retaining a thick nitrogen atmosphere are now readily understood. The low temperature of the protosaturnian nebula enabled Titan to acquire the moderately volatile compounds methane and ammonia (later converted to nitrogen) in addition to water. The higher temperatures of Jupiter’s moons, which were closer to the Sun, prevented them from acquiring such an atmosphere.

1. According to the passage, Titan differs atmospherically from Ganymede and Callisto because of a difference in

A. rate of heat loss

B. proximity to the Sun

C. availability of methane and ammonia

D. distance from its planet

6.GRE阅读理解绿皮书答案及翻译 篇六

early twentieth century differed in important ways from the

slave spirituals. Whereas spirituals were created and

disseminated in folk fashion, gospel music was composed,

published, copyrighted, and sold by professionals.

Nevertheless, improvisation remained central to gospel music.

One has only to listen to the recorded repertoire of gospel

songs to realize that Black gospel singers rarely sang a song

precisely the same way twice and never according to its exact

musical notation. They performed what jazz musicians call

“head arrangements” proceeding from their own feelings and

from the way “the spirit” moved them at the time. This

improvisatory element was reflected in the manner in which

gospel music was published. (122 words)

1.The author mentions “folk fashion” most likely in order to

(A) counter an assertion about the role of improvisation

in music created by Black people

(B) compare early gospel music with gospel music

written later in the twentieth century

(C) make a distinction between gospel music and

slave spirituals

(D) introduce a discussion about the dissemination of

slave spirituals

(E) describe a similarity between gospel music and

slave spirituals

10.Of the following sentences, which is most likely to

have immediately preceded the passage?

(A) Few composers of gospel music drew on traditions

such as the spiritual in creating their songs.

(B) Spirituals and Black gospel music were derived

from the same musical tradition.

(C) The creation and singing of spirituals, practiced by

Black Americans before the Civil War, continued

after the war.

(D) Spirituals and gospel music can be clearly

distinguished from one another.

(E) Improvisation was one of the primary characteristics

of the gospel music created by Black musicians.

Biologist know that some marine algae can create clouds by producing the gas dimethylsulphide (DMS), which reacts with oxygen in air above the sea to form solid particles. These particles provide a surface on which water vapor can condense to form clouds. Lovelock contends that this process is part of global climatic-control system. According to Lovelock, Earth acts like a super organism, with all its biological and physical systems cooperating to keep it healthy. He hypothesized that warmer conditions increase algal activity and DMS output, seeding more clouds, which cool the planet by blocking out the Sun. Then, as the climate cools, algal activity and DMS level decrease and the cycle continues. In response to biologists who question how organisms presumably working for their own selfish ends could have evolved to behave in a way that benefits not only the planet but the organisms as well, cooling benefits the algae, which remain at the ocean surface, because it allows the cooled upper layers of the ocean to sink, and then the circulating water carries nutrients upward from the depths below. Algae may also benefit from nitrogen raining down from clouds they have helped to form.

9. According to the passage, which of the following occurs as a result of cooling in the

upper layers of the ocean?

A. The concentration of oxygen in the air above the ocean’s surface decreases.

B. The concentration of DMS in the air above the ocean’s surface increases.

C. The nutrient supply at the surface of the ocean is replenished.

D. Cloud formation increases over the ocean.

E. Marine algae make more efficient use of nutrients.

10. Which of the following is most similar to the role played by marine algae in the

global climate control system proposed by Lovelock?

A. A fan that continually replaces stale air in a room with fresh air from outside.

B. A thermostat that automatically controls an air-conditioning system.

C. An insulating blanket that retains heat.

D. A filter used to purify water.

E. A dehumidifier that constantly removes moisture from the air in a room.

11. The passage mentions the possible benefit to algae of nitrogen falling down in the

rain most likely in order to

A. provide support for Lovelock’s response to an objection mentioned in the passage

B. suggest that the climatic effects of DMS production have been underestimated

C. acknowledge that Lovelock’s hypothesis is based in part on speculation

D. demonstrate that DMS production alters the planet in more than one way

E. assert that algae are the sole beneficiaries of DMS production

2. 长阅读(直通车Part IV: Long passages passage 4)

“Blues is for singing,” writes folk musicologist Paul Oliver, and “is not a form of folk song

that stands up particularly well when written down.” A poet who wants to write blues can attempt

to avoid this problem by poeticizing the form—but literary blues tend to read like bad poetry rather than like refined folk song. For Oliver, the true spirit of the blues inevitably eludes the self-conscious imitator. However, Langston Hughes, the first writer to grapple with these difficulties of blue poetry, in fact succeeded in producing poems that capture the quality of genuine, performed blues while remaining effective as poems. In inventing blues poetry, Hughes solved two problems: first, how to write blues lyrics in such a way that they work on the printed page, and second, how to exploit the blues form poetically without losing all sense of authenticity.

There are many styles of blues, but the distinction of importance to Hughes is between the genres referred to as “folk blues” and “classic blues.” Folk blues and classic blues are distinguished from one another by differences in performers (local talents versus touring professionals), patronage (local community versus mass audience), creation (improvised versus composed), and transmission (oralversus written). It has been a commonplace among critics that Hughes adopted the classic blues as the primary model for his blues poetry, and that he writes his best blues poetry when he tries least to imitate the folk blues. In this view, Hughes’ attempts to imitate the folk blues are too self-conscious, too determined to romanticize the African American experience, too intent on reproducing what he takes to be the quaint humor and naïve simplicity of the folk blues to be successful.

But a more realistic view is that by conveying his perceptions as a folk artist ought to—through an accumulation of details over the span of his blues oeuvre, rather than by overloading each poem with quaintness and naivety–Hughes made his most important contributions to the genre. His blues poems are in fact closer stylistically to the folk blues on which he modeled them than to the cultivated classic blues. Arnold Rampersad has observed that virtually all of the poems in the 1927 collection in which Hughes essentially originated blues poetry fall deliberatively within the “range of utterance” of common folk. This surely applies to “Young Gal’s Blues,” in which Hughes avoids the conventionally “poetic” language and images that the subjects of death and love sometimes elicit in his ordinary lyric poetry. To see what Hughes’ blues poetry might have been like if he had truly adopted the classic blues as his model, one need only look to “Golden Brown Blues,” a song lyric Hughes wrote for composer W.C. Handy. Its images, allusions, and diction are conspicuously remote from the common “range of utterance.”

1. The primary purpose of the passage is to

A. describe the influence of folk and classic blues on blues poetry

B. analyze the effect of African American culture on blues poetry

C. demonstrate that the language used in Hughes’ blues poetry is colloquial

D. defend Hughes’ blues poetry against criticism that it is derivative

E. refute an accepted view of Hughes’ blues poetry style

2. The author of the passage uses the highlighted quotation primarily to

A. indicate how blues poetry should be performed

B. highlight the difficulties faced by writers of blues poetry

C. support the idea that blues poetry is a genre doomed to fail

D. illustrate the obstacles that blues poetry is unable to overcome

E. suggest that written forms of blues are less authentic than sung blues

3. It can be inferred from the passage that, as compared with the language of “Golden Brown Blues,”

the language of “Young Gal’s Blues” is

A. more colloquial

B. more melodious

C. marked by more allusions

D. characterized by more conventional imagery

E. more typical of classic blues song lyrics

4. According to the passage, Hughes’ blues poetry and classic blues are similar in which of the

following ways?

A. Both are improvised

B. Both are written down

C. Both are intended for the same audience

D. Neither uses colloquial language

E. Neither is professionally performed

Benovians set their clocks back an hour for the winter. The result is that, during winter’s short days, it is light when most commuters drive to work, but dark when they drive back home. Darkness contributes to accidents. Changing the clocks, however, does not actually increase the amount of driving done in the dark, so it is unlikely to have any effect on Benovia’s automobile accident rate.

11. Which of the following is an assumption on which the argument relies?

A. The average number of hours that Benovians drive when it is dark is greater for days during the

winter than for days during other times of the year.

B. In Benovia, hazards to safe driving that are made worse by darkness are as likely to occur in the

morning as in the evening.

C. The majority of cars on Benovia’s roads during a given day are those of people commuting to or

from work.

D. The majority of automobile accidents in Benovia take place when it is dark.
