V5(V39) 4.肌肉疲劳什么的。一开始一个noble prize的人说the function of muscle will brake when muscle detects high level of lactic acid。但是后来有几个Canadian scientist做了个实验发现the muscle acts so even when the level of lactic acid is low,然后又有个什么实验(不记得了)。最后一段说其实第一段的那个theory不是完全的错,但是真正决定什么时候stop the muscle function的是neural system。所以这个过程是subjective而不是Objective(有道题问了这个)。
V8:(710)
Theory 1: muscles go into automated brake when lactic acid builds up after exhausting exercise, leading to fatigue.
Theory Two: psychologists argue central nervous system controls the sense of extreme fatigue to keep body from collapse; psychologists say that theory 1 is right about lactic build up, however wrong in the "location".( location=Central nervous system)

注意highlight的部分
Interestingly —or unnervingly, depending on how you look at it— some researchers are uncovering evidence that Stanovnik’s rule of thumb might be right. A spate of recent studies has contributed to growing support for the notion that the origins and controls of fatigue lie partly, if not mostly, within the brain and the central nervous system. The new research puts fresh weight to the hoary coaching cliché: you only think you’re tired.From the time of Hippocrates, the limits of human exertion were thought to reside in the muscles themselves, a hypothesis that was established in 1922 with the Nobel Prize-winning work of Dr. A.V. Hill. The theory went like this: working muscles, pushed to their limit, accumulated lactic acid.When concentrations of lactic acid reached a certain level, so the argument went, the muscles could no longer function. Muscles contained an ‘‘automatic brake,’’ Hill wrote,‘‘carefully adjusted by nature.’’Researchers, however, have long noted a link between neurological disorders and athletic potential. In the late 1800’s, the pioneering French doctor Philippe Tissié observed that phobias and epilepsy could be beneficial for athletic training. A few decades later, the German surgeon August Bier measured the spontaneous long jump of a mentally disturbed patient, noting that it compared favorably to the existing world record. These types of exertions seemed to defy the notion of built-in muscular limits and, Bier noted, were made possible by‘‘powerful mental stimuli and the simultaneous elimination of inhibitions.’’Questions about the muscle-centered model came up again in 1989 when Canadian researchers published the results of an experiment called Operation Everest II, in which athletes did heavy exercise in altitude chambers. The athletes reached exhaustion despite the fact that their lactic-acid concentrations remained comfortably low. Fatigue, it seemed, might be caused by something else.In 1999, three physiologists from the University of Cape Town Medical School in South Africa took the next step. They worked a group of cyclists to exhaustion during a 62-mile laboratory ride and measured, via electrodes, the percentage of leg muscles they were using at the fatigue limit. If standard theories were true, they reasoned, the body should recruit more muscle fibers as it approached exhaustion — a natural compensation for tired, weakening muscles.Instead, the researchers observed the opposite result. As the riders approached complete fatigue, the percentage of active muscle fibers decreased, until they were using only about 30 percent. Even as the athletes felt they were giving their all, the reality was that more of their muscles were at rest.Was the brain purposely holding back the body?‘‘It was as if the brain was playing a trick on the body, to save it,’’says Timothy Noakes, head of the Cape Town group. ‘‘Which makes a lot of sense, if you think about it. In fatigue, it only feels like we’re going to die. The actual physiological risks that fatigue represents are essentially trivial.’’From this, Noakes and his colleagues concluded that A.V. Hill had been right about the automatic brake, but wrong about its location.They postulated the existence of what they called a central governor:a neural system that monitors carbohydrate stores, the levels of glucose and oxygen in the blood, the rates of heat gain and loss, and work rates. The governor’s job is to hold our bodies safely back from the brink of collapse by creating painful sensations that we interpret as unendurable muscle fatigue.Fatigue, the researchers argue, is less an objective event than a subjective emotion —the brain’s clever, self-interested attempt to scare you into stopping.The way past fatigue, then, is to return the favor: to fool the brain by lying to it, distracting it or even provoking it. (That said, mental gamesmanship can never overcome a basic lack of fitness. As Noakes says, the body always holds veto power.)‘‘Athletes and coaches already do a lot of this instinctively,’’Noakes says.‘‘What is a coach, after all, but a technique for overcoming the governor?’’The governor theory is far from conclusive, but some scientists are focusing on a walnut-size area in the front portion of the brain called the anterior cingulate cortex. This has been linked to a host of core functions, including handling pain, creating emotion and playing a key role in what’s known loosely as willpower. Sir Francis Crick, the co-discoverer of DNA, thought the anterior cingulate cortex to be the seat of the soul. In the sports world, perhaps no soul relies on it more than Jure Robic’s.Some people‘‘have the ability to reprocess the pain signal,’’ says Daniel Galper, a senior researcher in the psychiatry department at the University of Texas Southwestern Medical Center at Dallas. ‘‘It’s not that they don’t feel the pain; they just shift their brain dynamics and alter their perception of reality so the pain matters less. It’s basically a purposeful hallucination.’’Noakes and his colleagues speculate that the central governor theory holds the potential to explain not just feats of stamina but also their opposite: chronic fatigue syndrome (a malfunctioning, overactive governor, in this view).Moreover, the governor theory makes evolutionary sense. Animals whose brains safeguarded an emergency stash of physical reserves might well have survived at a higher rate than animals that could drain their fuel tanks at will.The theory would also seem to explain a sports landscape in which ultra-endurance events have gone from being considered medically hazardous to something perilously close to routine. The Ironman triathlon in Hawaii —a 2.4-mile swim, 112-mile bike ride and marathon-length run—was the ne plus ultra in endurance in the 1980’s, but has now been topped by the Ultraman, which is more than twice as long. Once obscure, the genre known as adventure racing, which includes 500-plus-mile wilderness races like Primal Quest, has grown to more than 400 events each year. Ultramarathoners, defined as those who participate in running events exceeding the official marathon distance of 26.2 miles, now number some 15,000 in the United States alone. The underlying physics have not changed, but rather our sense of possibility. Athletic culture, like Robic, has discovered a way to tweak its collective governor.

DAVID ALLAN Saint Joseph's University dallan@sju.edu
This study examines the effects of popular music in advertising to determine both the theoretical (the effect of popular music on the processing of advertising messages) and practical (the design of more effective advertisements using popular music) implications. An experiment is reported that tested the effects of three integrations of popular music in advertising: original lyrics, altered lyrics, and instrumentals (plus a control treatment with no music) on attention and memory. The results indicated that song vocals, either original or altered, are more effective stimuli of advertising effects than instrumentals or no popular music.
But Kahneman (1973) said that attention describes some internal mechanisms that determine the significance not the relevance of stimuli. This suggests that popular music with high or low personal significance will lead to greater or lesser attention to the integrated advertising messages; popular music vocals will be more attention-getting than other treatments; and original popular vocals with high personal significance will be the most effective at getting the attention of the individual.
Popular music with original vocals was a more effective stimulus of attention and memory when high in personal significance and popular music with altered vocals was a more effective stimulus of attention and memory when low in personal significance
The individuals in this experiment processed songs and artists they considered high in personal significance differently from those that were low in significance.... When the artist was significant, the original vocal led to greater brand attention but when the artist was not significant, the altered vocal led to greater brand attention.... It suggests that the level of significance of the music and/or the artist can affect involvement possibly resulting in different processing of the advertising messages.
and/or the artist can affect involvement possibly resulting in different processing of the advertising messages. While high personal significance can be a possible explanation for the attentiongaining value of original vocals, low personal significance cannot adequately explain the attention-gaining value of altered vocals. Three possible explanations include thenoveltyof hearing a popular song with altered lyrics (especially the first time); irritationcaused by the changed lyrics; and/or the lack of fit of the song or the artist with the brand. All of these could have been attention-gaining stimuli causing greater attention to the brand and the song. It is clear, however, that lyrics (either original or altered) are important and that even though an interaction was observed for just one song and artist ("The Middle" by Jimmy Eat World) based on the lyrics, the results are of practical importance to advertisers for two primary reasons. First, the use of no music or an instrumental version of a popular song should be avoided. Second, if the advertiser is able to use a popular song that is personally significant to the target market of the brand, then the original vocal version should be used, but if not, an altered vocal version should be considered.
Either way, personalsignificance plays a role in the effectiveness of popular music in advertising on attention and memory, brand memory were observed for one of the brands (Sony) for both the song ("Without Me") and the artist (Eminem), with some apparent significant effects for genders. It is interesting to note that for the Kodak brand, males were observed to have greater memory for the brand than females when the song and the artist ("The Middle" by Jimmy Eat World) were highly significant but that females had greater memory for the brand when the song and the artist were low in personal significance. This could suggest that males are more sensitive to the level of personalsignificancethey have for advertising messages integrated in popular music than females, but this would need future research.

第三篇~~~ 上来竟然有一屏半,这个长啊,是关于暗黑物质的
第一段:科学家猜测暗黑物质在宇宙中有很多啦
第二段:以往的科学手段测不出暗黑物质,科学家只能通过一个实验测定。这个测试是通过暗黑物质对其他星球的光造成的折射这种原理进行的
第三段:看到过暗黑物质,但不如设想能看到的多。而且其实它们主要在我们的星系,而不在outer space, where orginally expected to have more 黑物质(此处有题)
问题二,问在新的发现之前scientist 没有预料到什么,我选的是没想到 这种物质m... 会在galaxy center的比例那么多。这题确定!(因为文中最后一段说本来科学家本来hypothesis的是这种物质在 galaxy outer area 会比center 更多,结果新的发现是反过来的,读到这里时就觉得这个很可能是个考点)
问题三,有个高亮短语好像在这里 scientist before determine many equipments.. ... they are reluctant to estimate the quantity of 这种物质, 问有什么作用, 正确选项应该表达这个意思的那个: 科学家觉得应该还有更多这种物质的。(我理解是这种物质在科学家眼里应该很多的只是现阶段由于技术的原因没被发现而已或者detect不到而已)
In the 1980's, astronomer BohdanPaczynski proposed a way of determining whether the enormous dark haloconstituting the outermost part of the Milky Way galaxy is composed of MACHO's(massive compact halo objects), which are astronomical objects too dim to bevisible. Paczynski reasoned that ifMACHO's make up this halo, a MACHO would occasionally drift in front of a starin the Large Magellanic Cloud, a bright galaxy near the Milky Way. The gravity of a MACHO that had so drifted,astronomers agree, would cause the star's light rays, which would otherwisediverge, to bend together so that, as observed from Earth, the star wouldtemporarily appear to brighten, a process known as microlensing. Because many individual stars are ofintrinsically variable brightness, some astronomers have contended that the brighteningof intrinsically variable stars can be mistaken for microlensing. However, whereas the different colors oflight emitted by an intrinsically variable star are affected differently whenthe star brightens, all of a star's colors are equally affected bymicrolensing. Thus, if a MACHO magnifiesa star's red light tenfold, it will do the same to the star's blue light andyellow light. Moreover, it is highlyunlikely that a star in the Large Magellanic Cloud will undergo microlensingmore than once, because the chance that a second MACHO would pass in front ofexactly the same star is minuscule.

黑物质叫Black Matter。文章还提到一个东西很重要,是“Neutralino”,好像有题。黑物质还分hot 和cold。我找来的Neutralino和black Matter的关系,也就这个还跟原文沾点儿边:
As a heavy, stable particle, the lightest neutralino is an excellent candidate to comprise the universe's cold dark matter. In many models the lightest neutralino can be produced thermally in the hot early universe and leave approximately the right relic abundance to account for the observed dark matter. A lightest neutralino of roughly 10–10000 GeV is the leading weakly interacting massive particle (WIMP) dark matter candidate.
Neutralino dark matter could be observed experimentally in nature either indirectly or directly. In the former case, gamma ray and neutrino telescopes look for evidence of neutralino annihilation in regions of high dark matter density such as the galactic or solar center. In the latter case, special purpose experiments such as the Cryogenic Dark Matter Search (CDMS) seek to detect the rare impacts of WIMPs in terrestrial detectors. These experiments have begun to probe interesting supersymmetric parameter space, excluding some models for neutralino dark matter, and upgraded experiments with greater sensitivity are under development.
第一段讲:宇宙中大家知道的物质只占了5%,剩下的都是暗物质.剩下的不记得了.第一段没什么出题点
第二段:提问,暗物质是由什么组成的?P和N不是,接下来是"Nor can more than a few of Neutrino怎么怎么的,意思是Neutrino也不是暗物质. 接下来高亮"一个关于newtrino的实验,说它很轻啦,速度很快啦,因此很hot "总之也不是dark matter.
第三段: 记得个fit的词(我理解是根据以上neutrino特征的反面推出的dark matter的特征), 能fit dark matter的物质具有的特点是cold, sluggish等等. 貌似在现在的cosmatic中不存在,但是在standard的假说中有一种neutranilo的物质符合
第四段: 主要讲neutronilo的,这里提到它不被electromagnetic怎么着(在比较俩个N不同的选项里出现),同时它又是最轻的,它又很stable, 因为如果不够轻的话就会不stable从而被分成俩个更轻的(很绕的逻辑),
第二段和第四段非常长,而且有很多细节题.
第一题:高亮的实验的作用
记得的选项是:1,回答段首的问题.2,支持前面那句话"nor more than".3,为了第三段什么的.我选了第二个.
第二题:Neutrino 和 neutranilo的描述哪个正确(以下简称n1,n2)

widely held view物种灭绝是因为地球上发生catastrophic
关于catastrophe 在阅读大全上找了个相关的,给大家参考下 答案EDADBC
Although numbers of animals in a given region may fluctuate from year to year, the fluctuations are often temporary and, over long periods, trivial. Scientists have advanced three theories of population control to account for this relative constancy.
The first theory attributes a relatively constant population to periodic climatic catastrophes that decimate populations with such frequency as to prevent them from exceeding some particular limit. In the case of small organisms with short life cycles, climatic changes need not be catastrophic: normal seasonal changes in photoperiod (daily amount of sunlight), for example, can govern population growth. This theory—the density-independent view—asserts that climatic factors exert the same regulatory effect on population regardless of the number of individuals in a region.
A second theory argues that population growth is primarily density-dependent—that is, the rate of growth of a population in a region decreases as the number of animals increases. The mechanisms that manage regulation may vary. For example, as numbers increase, the food supply would probably diminish, which would increase mortality. In addition, as Lotka and Volterra have shown, predators can find prey more easily in high-density populations. Other regulators include physiological control mechanisms: for example, Christian and Davis have demonstrated how the crowding that results from a rise in numbers may bring about hormonal changes in the pituitary and adrenal glands that in turn may regulate population by lowering sexual activity and inhibiting sexual maturation. There is evidence that these effects may persist for three generations in the absence of the original provocation. One challenge for density-dependent theorists is to develop models that would allow the precise prediction of the effects of crowding.
A third theory, proposed by Wynne-Edwards and termed “epideictic,” argues that organisms have evolved a “code” in the form of social or epideictic behavior displays, such as winter-roosting aggregations or group vocalizing; such codes provide organisms with information on population size in a region so that they can, if necessary, exercise reproductive restraint. However, Wynne-Edwards’ theory, linking animal social behavior and population control, has been challenged, with some justification, by several studies.
1. The primary purpose of the passage is to
(A) argue against those scientists who maintain that animal populations tend to fluctuate
(B) compare and contrast the density-dependent and epideictic theories of population control
(C) provide example of some of the ways in which animals exercise reproductive restraint to control their own numbers
(D) suggests that theories of population control that concentrate on the social behavior of animals are more open to debate than are theories that do not
(E) summarize a number of scientific theories that attempt to explain why animal populations do not exceed certain limits
2. It can be inferred from the passage that proponents of the density-dependent theory of population control have not yet been able to
(A) use their theory to explain the population growth of organisms with short life cycles
(B) reproduce the results of the study of Christian and Davis
(C) explain adequately why the numbers of a population can increase as the population’s rate of growth decreases
(D) make sufficiently accurate predictions about the effects of crowding
(E) demonstrate how predator populations are themselves regulated
3. Which of the following, if true, would best support the density-dependent theory of population control as it is described in the passage?
(A) As the number of foxes in Minnesota decrease, the growth rate of this population of foxes begins to increase.
(B) As the number of woodpeckers in Vermont decreases, the growth rate of this population of woodpeckers also begins to decrease.
(C) As the number of prairie dogs in Oklahoma increases, the growth rate of this population of prairie dogs also begins to increase.
(D) After the number of beavers in Tennessee decreases, the number of predators of these beavers begins to increase.
(E) After the number of eagles in Montana decreases, the food supply of this population of eagles also begins to decrease.
4. According to the Wynne-Edwards theory as it is described in the passage, epideictic behavior displays serve the function of
(A) determining roosting aggregations
(B) locating food
(C) attracting predators
(D) regulating sexual activity
(E) triggering hormonal changes
5. The challenge posed to the Wynne-Edwards-theory by several studies is regarded by the author with
(A) complete indifference
(B) qualified acceptance
(C) skeptical amusement
(D) perplexed astonishment
(E) agitated dismay
6. Which of the following statements would provide the most of logical continuation of the final paragraph of the passage?
(A) Thus Wynne-Edwards’ theory raises serious questions about the constancy of animal population in a region.
(B) Because Wynne-Edwards’ theory is able to explain more kinds of animal behavior than is the density-dependent theory, epideictic explanations of population regulation are now widely accepted.
(C) The results of one study, for instance, have suggested that group vocalizing is more often used to defend territory than to provide information about population density.
(D) Some of these studies have, in fact, worked out a systematic and complex code of social behavior that can regulate population size.
(E) One study, for example, has demonstrated that birds are more likely to use winter-roosting aggregations than group vocalizing in order to provide information on population size.作者: caicainiao 时间: 2011-5-11 15:54

P1. A travel guide mentioned the existence of sea serpents based on the recent recovery of huge and amorphous(无定形的,无组织的)organisms from the ocean. However, little was known about the true identity of these organisms.
P2.Recent scientific findings provided unequivocal evidence that these organisms are in fact a type of whale.
P3.Due to the mystery-mongering 传奇的传播 attitude of writers on this topic, it may take longer for the general public to accept the fact suggested by recent scientific findings.
v2 P1:讲述海怪的存在,有引用好像是导游还是什么人的话,说明有海怪存在(这里有题,会问为什么引用这个话,我选择说明在这个时候还没有人去研究海怪传说的真实性.)接着距离说明很多地方有残骸washed ashore.2001年的例子,2003年的例子,还有提到1988年的例子,(是智利的一个海岸?)说前一次在1988年,后来还有残骸出现.(后面这个有题)
P2:就讲澳洲的科学家着手研究这些残骸.欲采取DNA验证手段.有些残骸证明是抹香鲸(perm whale, cachalot)的.大多数残骸都年代久远,因此很难提取DNA,但是分析其纤维组织结构也能证明是类似动物身上的组织.

一个原因是传统的测量方法没有办法真正测出服务业的增长情况。because it has been concentrated in improved quality of services. Yet traditional measures of manufacturing productivity have shown significant increases despite the under measurement of quality, whereas service productivity has continued to stagnate.
然而又有一些人把这个归因于政府的赤字。Budget deficit.如果federal budget deficit 低,利率interest也就低,对于新技术的投资就多。但是服务业并不着急使用新技术,服务业的managers 不能广泛运用新技术。一些公司的情况说明如果managers 能够运用新技术,挑选熟练地员工,那么服务业的生产率一定会上升的。但是企业间不断地兼并以及政府不恰当的调节,使得经理们不能专注于这些正确的策略。

service sector in US
主要是讲美国为什么service sector productivity无法增长而manufacturingsector productivity却一直保持增长。讨论了各种各样的观点,但作者都认为不靠谱。文章最后一句有作者认为的可能的观点。
记得的题目包括:
a. 进入80年代之前的manufacturing sector performance怎么样,答案应该是poorly(原文有讲80年代开始之后productivity有大幅提高貌似)
b. 同上(想起来的时候我会过来补充的)。。
v3
1945年到1965年间美国经济productivity 一直在以每年3%的年增长率增长,但1970年以后就下降到了只有1%。是什么原因造成的呢? 绝对不是manufacturing sector。因为自从1980年以后,制造业的增长使美国一跃成为世界制造业的领头羊【此处出题问 “what can be infered about制造业的状况,immediately prior to 1980” 这里兰州不同意之前一篇寂静的观点,他选的是behavioring relavtively poor,但是问题里有immediately这个词,我选的是取得了较大进步,因为只有1980年前取得了较大进步,之后才能making America one of the领头羊,大家自己斟酌】 虽然制造业进步很大,但是它只占美国经济一小部分。1992年,制造业只雇佣了美国19.2%的工人;而服务业(service -producing )雇佣了70%的员工。虽然在1970年后,服务业的生产率也在提高,但提高的速度却在减慢。对于减慢的原因以及服务业和制造业之间的差距,有以下几种解释:
一个原因是传统的测量并有反应质量。因为服务业可能更注重于质量的提高。 Yet traditional measures ofmanufacturing productivity have shown significant increases despite the undermeasurement of quality, whereas service productivity has continued to stagnate.另一些人蛋逼说,是因为制造业的员工面临fiercer的国际竞争,这促使他们提高效率,而服务业面临的竞争较少,所以他们没有动力。但事实并非如此,制造业所面临的压力常常被夸大了【另一篇寂静里说的是服务业,兰州记得是制造业】。【此处有题,答案就是制造业的压力被夸大,选项和原文就是把“夸大”这个词做了不同的翻译,一个overstated,一个exaggerated】。实事上,虽然的确有些制造业的员工因为国外的竞争而失去了工作,但更多的人失去工作是因为产品需求的增长缓慢。
还有一些人把这个归因于政府的Budget Deficit.如果federal budget deficit 低,利率interest也就低,对于新技术的投资就多。但是企业间不断地兼并以及政府不恰当的调节,使得经理们不能专注于这些正确的策略。

1.3.4 ice age
V1
ice age, 有一个神马理论推出其成因,好像是跟地球绕太阳公转有关系。其中有一位仁兄站出来由另一种说法,结尾科学家说有待考究(原文说的是要第二个新理论成立必须排除一些别的因数比如潮汐和海水什么•影响来着)
v2
关于怎么鉴定ice age的,第一段某M提出一种观点,某I发现ocean sediment的某种特质证明了这种观点,第二段某人发现陆地上的一些东西反驳了M,第三段说M的观点是对的,第二段的家伙和I不同是陆地和海洋的数据有差异。
在阅读大全上找到个这个很相似, 大家看看。有红有黄,黄色是正确答案,剩下红色是正确答案
Passage 18 (18/63)
Milankovitch proposed in the early twentieth century that the ice ages were caused by variations in the Earth’s orbit around the Sun. For sometime this theory was considered untestable, largely because there was no sufficiently precise chronology of the ice ages with which the orbital variations could be matched.
To establish such a chronology it is necessary to determine the relative amounts of land ice that existed at various times in the Earth’s past. A recent discovery makes such a determination possible: relative land-ice volume for a given period can be deduced from the ratio of two oxygen isotopes, 16 and 18, found in ocean sediments. Almost all the oxygen in water is oxygen 16, but a few molecules out of every thousand incorporate the heavier isotope 18. When an ice age begins, the continental ice sheets grow, steadily reducing the amount of water evaporated from the ocean that will eventually return to it. Because heavier isotopes tend to be left behind when water evaporates from the ocean surfaces, the remaining ocean water becomes progressively enriched in oxygen 18. The degree of enrichment can be determined by analyzing ocean sediments of the period, because these sediments are composed of calcium carbonate shells of marine organisms, shells that were constructed with oxygen atoms drawn from the surrounding ocean. The higher the ratio of oxygen 18 to oxygen 16 in a sedimentary specimen, the more land ice there was when the sediment was laid down.
As an indicator of shifts in the Earth’s climate, the isotope record has two advantages. First, it is a global record: there is remarkably little variation in isotope ratios in sedimentary specimens taken from different continental locations. Second, it is a more continuous record than that taken from rocks on land. Because of these advantages, sedimentary evidence can be dated with sufficient accuracy by radiometric methods to establish a precise chronology of the ice ages. The dated isotope record shows that the fluctuations in global ice volume over the past several hundred thousand years have a pattern: an ice age occurs roughly once every 100,000 years. These data have established a strong connection between variations in the Earth’s orbit and the periodicity of the ice ages.
However, it is important to note that other factors, such as volcanic particulates or variations in the amount of sunlight received by the Earth, could potentially have affected the climate. The advantage of the Milankovitch theory is that it is testable: changes in the Earth’s orbit can be calculated and dated by applying Newton’s laws of gravity to progressively earlier configurations of the bodies in the solar system. Yet the lack of information about other possible factors affecting global climate does not make them unimportant.
1. In the passage, the author is primarily interested in
(A) suggesting an alternative to an outdated research method
(B) introducing a new research method that calls an accepted theory into question
(C) emphasizing the instability of data gathered from the application of a new scientific method
(D) presenting a theory and describing a new method to test that theory
(E) initiating a debate about a widely accepted theory
2. The author of the passage would be most likely to agree with which of the following statements about the Milankovitch theory?
(A) It is the only possible explanation for the ice ages.
(B) It is too limited to provide a plausible explanation for the ice ages, despite recent research findings.
(C) It cannot be tested and confirmed until further research on volcanic activity is done.
(D) It is one plausible explanation, though not the only one, for the ice ages.
(E) It is not a plausible explanation for the ice ages, although it has opened up promising possibilities for future research.
3. It can be inferred from the passage that the isotope record taken from ocean sediments would be less useful to researchers if which of the following were true?
(A) It indicated that lighter isotopes of oxygen predominated at certain times.
(B) It had far more gaps in its sequence than the record taken from rocks on land.
(C) It indicated that climate shifts did not occur every 100,000 years.
(D) It indicated that the ratios of oxygen 16 and oxygen 18 in ocean water were not consistent with those found in fresh water.
(E) It stretched back for only a million years.
4. According to the passage, which of the following is true of the ratios of oxygen isotopes in ocean sediments?
(A) They indicate that sediments found during an ice age contain more calcium carbonate than sediments formed at other times.
(B) They are less reliable than the evidence from rocks on land in determining the volume of land ice.
(C) They can be used to deduce the relative volume of land ice that was present when the sediment was laid down.
(D) They are more unpredictable during an ice age than in other climatic conditions.
(E) They can be used to determine atmospheric conditions at various times in the past.
5. It can be inferred from the passage that precipitation formed from evaporated ocean water has
(A) the same isotopic ratio as ocean water
(B) less oxygen 18 than does ocean water
(C) less oxygen 18 than has the ice contained in continental ice sheets
(D) a different isotopic composition than has precipitation formed from water on land

(A) offer a note of caution
(B) introduce new evidence
(C) present two recent discoveries
(D) summarize material in the preceding paragraphs
(E) offer two explanations for a phenomenon

(C) corresponds with predictions already made by climatologists and experts in other fields
(D) confirms the record of ice volume initially established by analyzing variations in volcanic emissions
(E) provides data that can be used to substantiate records concerning variations in the amount of sunlight received by the Earth作者: caicainiao 时间: 2011-5-11 15:58

1.4.6 highland冶炼史
Peru还是Chile某highland的冶炼史
第一段大意是专家们猜想应该很久之前就有人在这个地方挖矿/冶炼,但一直没找到证据。所以他们只能一直认为是西班牙人去了之后才开始冶炼。但最近找到了一个证据,通过对附近一个湖里sediment的化学分析,确认了很久之前确实有冶炼活动。
第二段就详细说了整个research的过程。其中提到银的痕迹出现在14/15世纪,说明那时才有对银的冶炼活动。
题目包括:
a. 问第一段跟第二段的role,不记得具体的选项,但记住第二段是具体阐释就可以选到答案了。
b. 好像有一道是问通过对湖里sediment研究发现了什么?应该也很好选。。作者: caicainiao 时间: 2011-5-11 16:02
