passage175
Madagascar’s Mahafale cattle raisers have incorporated the prickly pear cactus into their pastoral economy, which depends on assisting their cattle
through the dry season
, when grass and water are scarce. Rather than relying on nomadism in the pursuit of water and pasture for their livestock, they have turned to cactus to keep stock alive. This has influenced the cattle raisers’ way of life, particularly in terms of diet and mobility. Women harvest cactus for their families to eat. Male herders work cactus as a vegetable crop for cattle. For these benefits, pastoralists sow, prune, and shape prickly pear into living fences around their corrals. In doing so, these herders have become cactus cultivators, which has reduced their mobility.
The Mahafale have abandoned their pastoralist way of life.这个程度有问题
The mobility of the Mahafale has been diminished这个减少是对的

passage176
Catherine Stimpson calls for a reassessment of literary merit based on affective standards—on how literary works make readers feel—rather than on the aesthetic standards traditionally used to define the canon, the body of literary works generally accepted as “great”. Stimpson advocates an alterative para canon for literary works, such as Louisa May Alcott’s Little Women, because she believes such works have been unjustifiably neglected by unsympathetic scholars. According to Stimpson, a para canonical work may or may not have literary value by traditional standards; rather, its worth consists in its “capacity to inspire love.”
Elizabeth Barnes criticizes Stimpson’s approach
as subjective
（这个不是和客观对应，而是uncritical 的意思） and therefore uncritical 【showing lack or improper use of critical standards or procedures】“Although Stimpson
never actually defines
（注意这个转折实际就是说，
Stimpson这个人定义这个了
）
‘love,’ she implies that a lovable work is one that so engages the reader that its worldview becomes inseparable from the reader’s own” (Stimpson acknowledges that the values reflected in Little Women may have subconsciously influenced her invention of the para canon). For Barnes ,the conflation of ethics and aesthetics implicit in Stimpson’s approach (in which “good ”can refer to something morally sound and/or above average in quality) demonstrates
the ambiguity
（这是一个特点）inherent in such concepts as goodness and love.

passage178
For most of the twentieth century, scholars generally accepted the proposition that nations are enduring entities that predated the rise of modern nation-states and that provided the social and cultural foundations of the state. This perspective has certainly been applied to Korea; most historians have assumed that the Korean nation has existed since the dawn of historical time. In recent years, however, Western scholars have questioned the idea of the nation as an enduring entity. Both Gellner and Anderson have argued, in their studies of European, Latin American, and Southeast Asian cases, that the nation is strictly a modern phenomenon, a forging of a common sense of identity among previously disparate social groups through the propagandizing efforts of activities of the modern state.
In short, it was the state that created
the nation, not the other way around.
（这个是文章的争论点）
he extent to which the creation of the nation fostered significantly greater social and cultural unity并不是主要说的social and cultural
Younger Koreanists, with Em prominent among them, have begun to apply this approach to Korea. These scholars, noting the isolated nature of village life in premodern Korea and the sharp difference in regional dialects, suggest that ordinary villagers could not possibly have thought of themselves as fellow countrymen of villagers in other regions. These scholars also not the elites, conversely, often had outward-looking, universalistic orientations, as did aristocracies elsewhere, such as in premodern Europe.
Finally, they observe that the very word for “nation” in Korean, minjok, is a neologism first employed by Japanese scholars as translation of the Western concept and that it was first appropriated by Korean activists in the early twentieth century.
They argue, therefore, that a Korean “nation” came into being only after that time.
Regarding the observation discussed in the highlighted sentence, the author would probably agree with which of the following statements这个是作者观点
It shows the inappropriateness of trying to apply Western concepts to the Korean experience.注意作者的观点是两个都是有问题的
In short, in the case of Korea we have an argument between “primordialists”,
who contend that
nations are natural and universal units of history, and “modernists”,
who assert that nations are
historically contingent products of modernity.
（这一句的主干部分是讲的
argument,
因此不是表达某一方观点的句子）
The positions of both groups seem problematic.
（注意这一部分说明了是在评价这两个观点）
It seems unlikely that in the seventh century the peoples of the warring states of Koguryo, Peakche, and Shilla all thought of themselves as members of a larger “Korean” collectivity. On the other hand, the inhabitants of the Korean peninsula had a much longer history —well over one thousand years—as a unified political collectivity than did the peoples studied by Gellner and Anderson. Not only does the remarkable endurance of the Korean state imply some sort of social and cultural basis for that unity, but the nature of the premodern Korean state as a centralized bureaucratic polity also suggests the possibility that the organizational activities of the state may have created a homogenous collectivity with a sense of shared identity much earlier than happened in the countries of western Europe that provide the model for “modernist” scholarship.

Data of modern and historic peasant communities suggest that individuals and communities specialize in ceramic production for trade primarily to offset subsistence shortfalls arising from inadequate or insufficient agricultural land. Harry investigated whether
this correlation of
ceramic specialization （要注意到这个上下文的关联）with agricultural marginality（close to the lower limit of qualification, acceptability, or function
:
barely exceeding the minimum requirements） occurred among prehistoric inhabitants of the American Southwest. At Arizona’s West Branch site, occupied A. D. 900-1100, abundant pottery manufacturing materials suggest villagewide ceramic production in excess of that needed for household purposes.

Although Klezmer—a style of traditional Jewish folk music from Eastern Europe—

首先，像这个题作者与some scholars的共同之处
回读的机会的确小
就是这一部分作用很大
下面的部分，主要还是产生了干扰选项，可以理解为这两个小分句，分别是author 与some scholars 的观点
the degree of resemblance between klezmer and the Roma, Greek, and Romanian traditions

passage184
The area of literary rights is confusing for scholars whose work focuses on collaborative materials particularly materials of earlier Native American writers. Questions arise over authorship and the determination of literary heirs. For example, recognition of heirs turns on the European-based assumption of the private ownership of a written statement. The first person to writer down an oral tale can become legally recognized as the owner of that version of the story, just as the first chemist to patent a tribal healing practice becomes the owner of the resulting chemical formula.
This instance on private rather than collective ownership
, （注意后面这一部分信息的作用是，来解释起源，同时不是主句的内容，并不是主要信息）
derived from the nineteenth-century notion of the autonomous, creative, authorial voice, flies in
the face of those who come from an oral tradition.
Thus
a scholar concerned with finding literary heirs in order to afford them the benefits of copyright laws
must
in so doing accede to legal concept of ownership that has been used to appropriate knowledge
from community-
based cultures.(

In Stanton the average number

（这里的点在于每车多）accident is consistently higher for accidents involving a taxicab than for those not involving a taxicab. （下面这一部分是来设计干扰选项的，但是，实际的强词是在上面的就是per）
Although all
Stanton taxicabs are equipped with passenger seat belts, taxicab drivers report that passengers tend not to use them. It is likely, therefore, that if taxicab passengers were required to use seat belts, the number of people injured per accident would soon be no higher for taxicabs than for other automobiles.
逻辑单题，应当首先知道，需要一个什么方向的答案，然后就是关注一下纠结的点是什么
换句话说，还是找一个逻辑相同或者相反的表述
而争论点，就相当于填空中的强词
而另一个方面就是逻辑关系
The number of people, including the driver, who occupy a vehicle is generally greater for taxicabs than for other vehicles.这里说每车人多，就是对的
Not all passengers in automobiles other than taxicabs use seat belts.
这个选项应该是证明，别的车应该也有一样的死亡率

when the growing temperature is also raised several
degrees.(就是说，在CO2浓度高的地方，产量高，温度也有帮助) Although enclosed cultivation is impractical in vineyards, increases
in yields from
grape cultivation in the open can be expected because emissions

这个题关键要看懂第二句的对比，削弱了什么，支持了什么
When grapes are grown in greenhouses, it is relatively easy to control the grape pests that thrive in air enriched with carbon dioxide.他因
Recent improvements in pest control have increased grape yields in many vineyards.
Increasing carbon dioxide levels in greenhouses has not been shown to improve the quality of grapes grown in greenhouses.
Increasing carbon dioxide levels in greenhouses increases the sweetness of raisins made from grapes grown in the greenhouses
As the carbon dioxide level in the open air increases, temperatures at the Earth’s surface will also increase
2. Which of the following would be most useful to determine the possibility that the grapes yields increase
with the raise of the temperature
?
A. Whether
increasing carbon dioxide levels
in greenhouses improves the eating quality of the grapes grown in the greenhouses
B. Whether in the future
the market
for grapes will be greater than it is now
C. Whether temperatures today often get so high in regions where grapes are grown that
the
grapes suffer serious damage
这里是说会不会有不好的影响
D. Whether the use of greenhouses for growing grapes serves
research purposes only
（

没提）
E. Whether the
economic
benefits that might be derived from a major increase in world grape production would outweigh any economic harm resulting from negative health effects associated with increased worldwide carbon dioxide levels
注意这种题目的错误选项是合理但不相关的，注意首先先把这个排掉
讨论可行性，所以就要提及是不是有副作用但是和这个因素出现相关的副作用，注意最后一个就没有提到
the raise of the temperature
这件事
总之，在选不出来的时候不要慌，先把凑数的选项删掉

passage187
One way to assess This is the American Earth, a collection of photographs selected and arranged by Nancy Newhall, is to apply Newshall’s own criteria for judging photographic art. Does this photographic essay achieve results impossible in other media? By contrasting the small with the vast

—Newhall exploits the camera’s ability to manipulate the size of an object, thereby challenging viewers
to question their conventional concepts of size.

passage190
The United States Civil Rights movement, which began in the 1950s and
gained momentum in
the 1960s and 1970s, owed a heavy debt to African American newspapers. This is not to suggest that the African American press caused the Civil Rights era. But its continual push
from 1910 to 1950 or more African American rights,
using a compelling form of advocacy
journalism rather than the standard objective newspaper style, allowed those
who in the 1950s
began pushing nationally for equality to start at a far higher level
than if the African American
press had not existed. This point has largely been missed by many Americans, who seen to
believe the Civil Rights era erupted from a
standstill

Except in special situations, human beings’ battle with mosquitoes will not be won by a simple
campaign to eliminate the insects. （这个是claim）(后面是一个例子)Social tradition and habits, it seems, do much to ensure continual contact between mosquitoes and people.
On the slopes of Mount Kilimanjaro, for
example, mosquitoes breed in the leaf axils of a plant called dracaena. Although dracaena is not a food plant for humans, its use as a hedge or boundary marker is is deeply rooted in tradition. Here, as in other parts of the world, human behavior ensures contact and conflict between people and mosquitoes.
I am not advocating a policy of live and let live; we already know that living with mosquitoes is very unpleasant. But until we accomplish the difficult task of understanding how our habits often perpetuate–even create–our problems,
efforts to resolve our battle with mosquitoes will
probably fail.

passage198
Only since the late 1960s have
literary scholars
attempted to establish an accurate and systematic literary history of women novelists. Many previous
histories
suffered from “Great Traditionalism,” an approach that, by limiting itself to a group of women writers termed “great,” ignored the diversity among women novelists.
These histories
excluded the minor novelists, who are the links in the chain that binds literary generations together, and who allow us to see the continuities in women’s writing. Given the distortions produced by this concentration on “great” writers, as well as the obviously problematic tendency of
many literary
scholars to apply stereotypes of femininity, it was not surprising that some literary scholars in the early 1960s
evaded the important issue of women’s sexual identity entirely(
这一点很明确
)
,
focusing
instead on the form and style of women’s writing. Such an approach,
while insightful and very
valuable（respect）, did not consider the crucial connections between women’s writing and changes in their legal and economic status.(critical)

passage201
Pueblo Bonito, the most impressive of the “great houses” at the prehistoric Chaco Canyon site in New Mexico, comprised over 600 rooms and 4 to 5 stories.
Traditional interpretations
have viewed the great houses as almost entirely residential, with some archaeologists estimating the population of Pueblo Bonito at 1,200.
But Windes
recently challenged this view by pointing out
the paucity of hearths recorded
during the excavation of Pueblo Bonito, which revealed only 3 upper-story hearths, in contrast to 59 ground-floor hearths: habituation rooms would have required hearths for cooking and heat.
It is possible, however, that
the collapse of upper-story floors disturbed evidence of upper-story hearths to such an extent that they were not revealed by early excavations such as those conducted by Pepper’s field crews in the 1890s and Judd’s in the 1920s.
Additionally,
reliance on room features for early population estimates is complicated by the Chacoan’s later remodeling, especially given Judd’s disinclination to destroy later structures and features to expose earlier ones. The failure of early excavations to strip off intact floors may have concealed evidence of hearths in upper-story rooms.
要读视角读层次
就中间提了一下不同的观点
Upper-story rooms with hearths were probably used for different purposes than were lower story rooms with hearths.这个和主题关系不是特别密
passage202
Since the 1970s, archaeological sites
in China’s Yangtze River region
have yielded evidence
of
sophisticated rice-farming societies that predate signs of rice cultivation elsewhere in East Asia by a thousand years.
Before this evidence was discovered
, it had generally been assumed that rice farming began farther to the south. This scenario was based
both on
the geographic range
of wild or free-living rice, which was not thought to extend as far north as the Yangtze,
and on
archaeological records of very early domestic rice from Southeast Asia and India (now known to be
not so old as first reported).（下面和上面是一个层次）
Proponents
of the southern-origin theory point out
that
early rice-farming societies along the Yangtze were already highly developed
and that
evidence for the first stage of rice cultivation is missing. （这里提了两点）
They
argue that the first hunter-gatherers
to develop rice
agriculture must have done so in this southern zone, within the apparent present-day geographic range of wild rice.

the conclusion that the author makes based on the 1984 survey?
A.
Areas south
（不应该说这个对象）
of the Yangtze basin currently have less wild-rice habitat than they once did.
B. Surveys since 1984 have shown wild rice populations along the upper Yangtze as well as along the middle and lower Yangtze. （这个选项没有削弱）

2. Based on the passage, skeptics of the idea that rice cultivation began in the Yangtze River region pointed to which of the following for support?
A. lack of evidence supporting the existence of rice-farming
societies
along the Yangtze at an early date （没有否认这一点）
B. lack of evidence regarding the initial stages of rice cultivation in the Yangtze region

A. The theory is based on an unconventional understanding of how
hunter-gatherers first

passage 204
The conventional story of the American colonists’ revolt against Britain holds that the founders of the United States established a form of government that
, although flawed by its leaders’ failure to
recognize the rights of women and African Americans, was nevertheless unsurpassed in
its
promise of human equality. There is, however, a cynical counterstory, which
details
the founders’ lust for property and their crass manipulation of the colonial population,
and characterizes
leaders（注意这一部分是一个细节的例子，因此不应该重点来概括）
like Thomas Jefferson
as having wielded promises
of equality merely
as deceptive tools, discarded
once the Revolution was won, and
as having deliberately allowed the United States
to be governed by a small, powerful elite.
Both of these stories assume that a homogeneous revolutionary leadership employed an equally homogeneous egalitarian discourse to justify its actions. Even a cursory examination of the public discourse from the period, however, makes it clear that the leadership was anything but homogeneous in its discourse, and that overall the relative emphasis placed on the words “liberty” and “property” was far greater than that placed on “equality”.
一定要看懂两个观点对立的核心点在哪
2. According to the passage, which of the following best summarizes the primary difference between two accounts of the American Revolution?

A. The first account acknowledges the
failure
of the revolutionary leaders to recognize the rights of women and African Americans, while the second does not address the issue of equal rights.
B. The first account claims that the government succeeded in its goal of providing equal rights for all of the colonists, while the second reports that
the new nation
was governed by a small, powerful elite.
C. The first account employs
traditional historical scholarship and sources
, while the second reports that new nation was governed by a small, powerful elite.
D. The first account suggests that the revolutionary leaders
sincerely
promised equality, while the second reports that the leaders’
false promises of equality
were a deceptive means of gaining colonists’ support.
E. The first account does not address the issue of
public discourse
, while the second describes how public discourse shaped the outcome of the Revolutionary War.
passage 206
African American painter Malvin Gray Johnson (1896-1934) grew up in urban environments, including New York City, but in 1934 visited and painted scenes from the small town of Brightwood, Virginia.（第一句背景）
Some critics
have celebrate the Brightwood paintings, which depict a vibrant natural landscape and close-knit Black community, as Johnson’s discovery of an “authentic” African American life in the rural South.
This view
, which reflects a common tendency to regard African American artists’ imagery as unmediated documentation of direct experience,
overlooks
Johnson’s interpretive thinking.
In truth
, Johnson’s conceptualization of the South was largely formed before he left New York, where he had studied the French expressionist Paul Cézanne. Johnson’s Brightwood paintings reflect Cézanne’s stylistic influence and tendency to present rural life as an idyllic alternative to modern industrialism.

passage 210
Having a larger assortment to choose from
increases
consumers’ expectations about matching their preferences
.
The heightened expectations
seem logical, since assortments containing more or more varied items should increase the degree to which preferences can be matched. In practice, however, as assortment size increases, the degree to which consumers realize better preference matches often rises relatively little. Larger assortments may not actually offer more variety, the market may simply not supply an envisioned offering, or in the absence of sophisticated search tools, consumers may miss a better preference match even if it is available. Therefore, larger assortments can increase the likelihood that expectations will not be met,
leaving consumers less satisfied with options chosen from larger rather than smaller assortments.
consumers’ anticipation of meeting specific expectations directly affects their satisfaction with a selected option 这一点是前面提到的
注意这个题的assumption是之前提到的，是提高了这种match 的期望 而不是
adjust
the preferences they had beforehand
换句话说，错误的选项，会有一些小点有问题，这个是需要注意的，这个就是adjust
passage 212
The recently announced discovery of the first known planet orbiting a pulsar (the ultradense, pulsating remnant off
the supernova explosion
of a star) turned out to be based on faulty data. Had this discovery been confirmed, theorists would have had difficulty accounting for the existence of such a planet. The supernova would certainly have destroyed any preexisting planets. This particular pulsar is relatively young, allowing little time for a new planet to have coalesced, and
it rotates relatively slowly, implying that it has not interacted with any nearby star since the supernova.
But newer evidence of a different pulsar with planets is more promising. This is a rapidly spurring “millisecond pulsar” thought to be a much older object that has pulled gaseous material from a stellar neighbor, causing its rotational speed to increase. Leftover, unconsumed gas around such a pulsar could, in theory, coalesce into planets. Or the pulsar’s radiation might have vaporized a companion star, providing new material for planetary formation.

passage 214
Marine ecosystems
certainly have less permanence than terrestrial ecosystems. Ashore, ecologists are not confronted with shifting ecological discontinuities, or with changes in the characteristic conditions of individual ecosystems, because, unless man intervenes, the tree line on a mountain or the passage between grassland and savannah remains approximately static over a human lifetime. It is only on the millennial scale that such boundaries migrate significantly, or that characteristic regional ecosystems disappear. Urban sprawl, deforestation, overgrazing, and intensive agriculture are accomplishing in a few decades what nature cannily do in centuries, but that sad fact does not alter the argument. Although the human population explosion can produce pressures that rapidly shift ecological boundaries and modify ecosystems ashore, it is paradoxically more difficult directly to modify the average locations of the ephemeral and shifting ecological boundaries of the sea. We can accomplish this only indirectly by atmospheric modification, resulting in a changed global climate and a shifted ocean circulation.
Indeed, if we are agreed that the regional characteristics of marine ecosystems are consequent on the characteristics of the physical environment, then we must assume that ecological conditions are as impermanent as the physical conditions themselves. And these, it is now well understood, are in continual flux and state of change at all scales of variability.

passage 215
W.E.B. Du Bois’ exhibit of African American history and culture at the 1900 Paris Exposition Universelle attracted the attention of a world of sociological scholarship whose value his work challenged. Du Bois believed that Spencerian sociologists failed in their attempts to gain

their work examined not deeds
but theories
（这一点对应第一个题） and
because
they gathered data not
to affect social progress

contributions

passage 217
Wildcats are improbable candidates for domestication. Like all felids [cats], wildcats are obligate carnivores, meaning they have a limited metabolic ability to digest anything except proteins. Wildcats live a solitary existence and defend exclusive territories, making them more attached to places than to people. Furthermore, cats do not perform directed tasks and
their actual utility
is debatable; even as mousers, in this latter role, terrier dogs and ferrets are preferable. （注意这些动物对应前文这一点，是例子的作用）Accordingly, there is little reason to believe an early agricultural community would have sought out and selected the wildcat as a house pet. Rather, the best inference is that wildcats exploiting human environments were simply tolerated by people and, over time and space, they gradually diverged from their “wild” relatives.

passage 220
Ecologists had assumed that trees in the consistently warm tropics grew at a slow but steady rate, unvarying from year to year. However, a study at La Selva, Costa Rica, showed that trees grew less in hotter years and more in cooler ones: between 1984 and 2000, dramatic differences occurred in the six species of trees studies, with trees adding twice as much wood in some cooler years as they did in the scorching El Nino year of 1997-1998. Because tree growth is an index of the balance
between photosynthesis
, in which trees absorb carbon dioxide (CO2) from the atmosphere and release oxygen,
and respiration
,
in which the opposite occurs
, the La Selva data were the first hint that rapidly rising global temperatures
, driven by human-generated emissions of CO2,
may be pushing tropical forests to release more CO2, thereby intensifying global warming. （注意这里没有调和与下面这个theory的关系）（这一句可以看出在温度高的时候长得慢，同时释放跟多CO2）This raised serious questions about a popular theory that tropical forests act as a sponge, soaking up much of the excess CO2 that humans pump into the atmosphere. The La Selva data are consistent with a model of global CO2 flux developed by Keeling, who concluded that the amount of CO2 taken up in tropical landmasses rose in cooler years and fell in hotter ones, accounting for year-to-year changes in the amount of CO2 that stays in the atmosphere.

passage 221
In the 2,000-year period immediately before European contact, many native groups of the Northern Plains of North America specialized in big-game hunting, subsisting primarily on bison. Bison routinely became fat-depleted in the spring, reducing their nutritional value,
yet these groups did not supplement their diets with the nutritious, fat-rich fish
（注意这里是说谁不吃）
that were abundantly available. Malainey et al. find a possible explanation in late-eighteenth- and early-nineteenth century accounts from three frontiersmen who had adapted to lean-meat diets during extended periods in the plains. Each had an opportunity to consume fish after extended meat dependence and upon eating it, became weak and ill. Malainey notes that prolonged lean meat dependence renders the body incapable of digesting lipids (fats), perhaps explaining native hunters’ fish avoidance.
passage 221
Migratory songbirds breeding in Eurasia’s temperate forests depend on a summer flush of insects, particularly caterpillars, to feed themselves and their offspring. In some places, these caterpillars are emerging earlier in responses to rising global temperatures. In theory, the songbirds could simply push up their departure from their winter quarters to catch the earlier flush of insect prey. If, however, the birds rely on a fixed cue such as increasing day length to begin flying north, they may be unable to adjust the timing of their migration. Precisely this disruption in the emergence of insects
relative to the timing of songbird migration
has been identified as the cause of a significant decline
in populations of pied flycatchers
in the Netherlands.
2. According to the passage, populations of insects preyed upon by pied flycatchers.
A. are finding less food as temperatures rise in the Eurasian forests that they inhabit
B. are endangered because of global warming
C. have recently experienced changes in the timing of their life cycles relative to the calendar
D. have recently begun inhabiting cooler climates largely unfrequented by pied flycatchers.
E. have increased significantly because of lack of predation.

passage 228
A recent exhibition of works by late-nineteenth-century painters Mary Cassatt, Berthe Morisot, and Eva Gonzales offered a rich visual
counterpart to
studies focusing new attention on the social and ideological forces that influenced their work. The paintings by Gonzales were particularly illuminating. Long marginalized by scholars as little more than an apprentice of Edouard Manet, Gonzales is revealed by the exhibition as possessing remarkable, if uneven, talents. Given the exhibition’s focus, and especially the provocative new emphasis on Gonzales, the accompanying catalog proved disappointing. There often-quoted essays by critics contemporary to the artists— essays in themselves noteworthy but historical artifacts nonetheless—provided the exhibition with its only critical readings. Thus, a significant opportunity for scholarly debate was not only lost but even seemed pointedly avoided.

When on an airplane, Consuelo never enjoys movies that have been widely recommended because the poor quality of the picture spoils her enjoyment. Since

it follows that she never enjoys movies on airplanes.
If a movie shown on an airplane is not widely derided, then it is invariable widely recommended.这里就是两种情况

passage 235
When rats are placed under conditions of stress, their adrenal glands immediately increase production of the hormone corticosterone, and soon thereafter the rats’ white blood cell count drops substantially. Yet rats without functioning adrenal glands experience little decrease in white blood cell count when placed under conditions of stress. It is likely, therefore, that an increase in corticosterone produced by a rat’s adrenal glands causes the rat’s white blood cell count to decrease.
For this paragraph, the author only mentions one increase and one drop.
passage 238
Because different mammalian species favor different environments, identifying and counting bones from prehistoric deposits in caves can reveal much about climatic change.
However, using large mammals’ bones can be problematic.(the sentences below serve to prove this sentence)
Some species, such as red deer, are very adaptable—
at home on both open may have traveled considerable distances
(paraphrase: The ability of some species to thrive in multiple types of environment) before being discarded: both carnivores and humans can have large hunting territories and bring home large animals quite unlike those near their den or campsite. Consequently, the bones of the small mammals found with cave sediments provide a better index of climate change they are generally more numerous, the species are more sensitive to environmental conditions, and few travel far within their short lives.
For the first time, you need not and should not read the details like examples or explanations, what you do should care is the overall structure and the function of each sentence.
passage 240
In the late 1990s, the Mars Global Surveyor spacecraft
detected
magnetized patches
of terrain near the north pole of Mars and also in the Terra Sirenum region, which is in the planet’s southern hemisphere.
Global magnetic is only a hypnosis
These magnetic features
may be
relics
of a global magnetic field in the vicinity of
several huge
,
ancient craters
in the Terra Sirenum region
, astronomers believe
these craters
were formed
some 3.8 billion years ago
from the impact of chunks of debris
pelting the inner solar system, where Mars orbits the Sun.
Chunks of debris->craters’ forming process-> Global magnetic field vanished
Global magnetic field vanished -> before crates formed
If a global magnetic field once existed on Mars, it must have vanished before
these craters
formed.
Such large impacts
beat rock to temperatures well above 600 degrees Celsius—high enough to erase any magnetic field that metallic particle within the rock strong
at the time the craters formed
, it would have
realigned
and remagnetized the articles as they cooled.
The Surveyor findings thus suggest the magnetic field vanished early in the planet’s 4.5 billion year existence
