没发过什么帖子 只是看 加 潜水 加看
先说三个问题
1.北京理工 大四 英语专业 每天学些不找边的泛读课 研究人怎么发声的语音学 还有华丽辞藻的文学及各个作家的正史野史 对于英语类的考试自信满满 终于明白考得是思维方式 结论： 英语好 最多说明你可以读懂题 （当然 多不懂题就该反省咯）
2. 不复习好容易心虚 心虚就容易背机经 背了就有投机心理
我一战620 惭愧 一个半月的全天 时间紧 精神上更紧张 身边没有战友 又怕看到成绩 模考我都怕 后来几天背机经直接导致我正式考试的时候 全都不思考 遇到机经像遇到救星 没有几题真正的经过了大脑的处理 于是我这次只看了数学的机经 结论： 有些人适合看机经 在考试的时候不会过分依赖 做题可以保持自己的思维 但有些人不适合看机经 原来可以打600 结果看了机经反而分低 不善于抵抗有答案的诱惑产生极大的依赖性 猜中题了导致大脑兴奋 投机心理太重
3.题目没做完的问题
我模考喜欢保证正确率 一般做不完 考前特意查了处罚
正式考试不免以身试法
M50 没有太多机经 没剩什么时间
V34 三道题没有做
事实证明没做会扣分 但我宁愿看着1分钟过去 也不乱选
连错或乱作肯定会加倍的 大家慎重
建议：本月语文比前两月的容易 大家放心
呵呵 本人下月再战 同仁一起努力！！！
ARGUMENT: 机经里没有
一个bussiness analysist 给provincia airline 的建议
事件：去年Provincia airline's profit declined 20%
分析师说： 1.原油价格暴涨 加大P公司的成本
2.P公司在五个城市新开通了一些线路 费钱
结论：每个同行都面对原油暴涨 但有的公司利润就升了 所以P公司的利润下降是由新增的航班线路导致的

1.黑人 不去北方工作的原因
现象：黑人在法律允许他们自由流动后还是流动性不大
老观点，他们不了解北方的就业情况
被否了 他们知道
作者观点：他们知道 不去 因为知道就算欧洲移民不去了 他们也找不到啥好工作
2.夏威夷
当时搜了点东西 很有用
Recent research shows that the hotspot itself may have moved with time. Some evidence comes from analysis of the orientation of the ancient magnetic field preserved by magnetite in ancient lava flows sampled at four seamounts (Tarduno et al., 2003): this evidence from paleomagnetism shows a more complex relationship than the commonly accepted view of a stationary hotspot. If the hotspot had remained above a fixed mantle plume during the past 80 million years, the latitude as recorded by the orientation of the ancient magnetic field preserved by magnetite 磁石should be constant for each sample and should also signify original cooling at the same latitude as the current Big Island of Hawaii. Comparisons with the traces of other hotspots also test if the Hawaiian-Emperor bend records a change in plate motion. Tarduno et al. (2009) have summarized evidence that the bend in the seamount chain may be caused by circulation patterns in the flowing solid mantle (mantle "wind") rather than a change in plate motion
Tarduno and his team were able to determine where the volcanoes formed by analyzing a mineral called magnetite in the rock samples. When hot magma from an erupting volcano cools, magnetite residues -- acting like miniature magnetic needles -- align with the Earth's magnetic pole and become locked in place as the rock solidifies. Researchers were able to verify the latitudes at which the Seamounts formed by determining the angles at which the magnetite had frozen.
18)夏威夷岛链（附背景资料）

第二篇是关于地理的，共四段，有点儿长，第一段主要讲一个chain of island是由火山岛和被淹没在海里面的死火山组成的，以及一些性质，第二段是讲，长期以来专家认为hotspot（貌似是这个，出现在第一段是chain of island一个比较重要的一部分）是不动的。第三段说通过磁场以及磁石，新发现上面提到的那个东西是要移动的（里面会有关于磁石的考题），第四段具体介绍磁石磁极的偏移是作为证明专家论断的一个重要依据。
想起来几个题目，关于磁石的，一个推断题，一个according的题目，两道题可以在第三段和第四段来定位，专家为了找到证明hotspot在移动的证据，就使用了磁石这个sample，但是这种sample不能在条件恶劣的地方找，因为那种地方（大概由于高温吧）磁石会melt，磁极会变化，当这些融化的磁石凝固后，磁极才会再次稳定。。。第四段就讲发现南部和北部的磁极polarility有偏差（偏差具体数值lz也给了），说明hotspot确实是移动了的。。。

However, certain “misplaced” volcanoes far from plate edges result from a second, independent mechanism that cools the deep interior of Earth. Because of its proximity to Earth’s core, the rock at the base of the mantle is much hotter than rock in the upper mantle. The hotter the mantle rock is, the less it resists flowing. Reservoirs of this hot rock collect in the base of the mantle. When a reservoir is sufficiently large, a sphere of this hot rock forces its way up through the upper mantle to Earth’s surface, creating a broad bulge in the topography. The “mantle plume” thus formed, once established, continues to channel hot material from the mantle base until the reservoir is emptied. The surface mark of an established plume is a hot spot—an isolated region of volcanoes and uplifted terrain located far from the edge of a surface plate. Because the source of a hot spot remains fixed while a surface plate moves over it, over a long period of time an active plume creates a chain of volcanoes or volcanic islands, a track marking the position of the plume relative to the moving plate. The natural history of the Hawaiian island chain clearly shows the movement of the Pacific plate over a fixed plume.
Q23:
It can be inferred from the passage that a chain of volcanoes created by a mantle plume would most likely be characterized byconstituent volcanoes that differ from each other in age
Q25:
According to the passage, a hot spot on Earth’s surface is an indication of which of the following?A plume of hot mantle rock originating near Earth’s core
3. 男人对女人的监护(guardian)是不是意味着男权（patriarchy)
第一段：一个人的观点女人要是没男人的guardian 也就没有某些权利
第二段：置疑证据1.这个documentation的资料 用的都是支持他观点的XXX,XXX,XXX的著作，但是那些也很有名的XXX,XXX,XXX就被他忽略了 这是不对的（有题）
2. 15世纪的罗马法不足以反映出情况（有题 15世纪之前的说法哪个对）
第三段： 让步转折It is true that .... （考高亮的作用 challange)作者自己的观点是：guardian 不一定就是patriarchy 的体现
好像出了题问作者观点和最后一句话的内容
还有一篇 不记得了
下面是可能有用的英文阅读材料

Non-avian dinosaurs suddenly became extinct approximately 65 million years ago. Many other groups of animals also became extinct at this time, including ammonites (nautilus-like mollusks), mosasaurs, plesiosaurs, pterosaurs, herbivorous turtles and crocodiles, most birds, and many groups of mammals.[4] This mass extinction is known as the Cretaceous–Tertiary extinction event. The nature of the event that caused this mass extinction has been extensively studied since the 1970s; at present, several related theories are supported by paleontologists. Though the general consensus is that an impact event was the primary cause of dinosaur extinction, some scientists cite other possible causes, or support the idea that a confluence of several factors was responsible for the sudden disappearance of dinosaurs from the fossil record.
At the peak of the Mesozoic, there were no polar ice caps, and sea levels are estimated to have been from 100 to 250 meters (300 to 800 ft) higher than they are today. The planet's temperature was also much more uniform, with only 25 °C (45 °F) separating average polar temperatures from those at the equator. On average, atmospheric temperatures were also much warmer; the poles, for example, were 50 °C (90 °F) warmer than today.[116][117]
The atmosphere's composition during the Mesozoic was vastly different as well. Carbon dioxide levels were up to 12 times higher than today's levels, and oxygen formed 32 to 35% of the atmosphere, as compared to 21% today. However, by the late Cretaceous, the environment was changing dramatically. Volcanic activity was decreasing, which led to a cooling trend as levels of atmospheric carbon dioxide dropped. Oxygen levels in the atmosphere also started to fluctuate and would ultimately fall considerably. Some scientists hypothesize that climate change, combined with lower oxygen levels, might have led directly to the demise of many species. If the dinosaurs had respiratory systems similar to those commonly found in modern birds, it may have been particularly difficult for them to cope with reduced respiratory efficiency, given the enormous oxygen demands of their very large bodies.[4]
Impact event
The asteroid collision theory, which was brought to wide attention in 1980 by Walter Alvarez and colleagues, links the extinction event at the end of the Cretaceous period to a bolide impact approximately 65.5 million years ago. Alvarez et al. proposed that a sudden increase in iridium levels, recorded around the world in the period's rock stratum, was direct evidence of the impact.[118] The bulk of the evidence now suggests that a 5 to 15 kilometer (3 to 9 mi) wide bolide hit in the vicinity of the Yucatán Peninsula, creating the 170 kilometers (110 mi) wide Chicxulub Crater and triggering the mass extinction.[119] Scientists are not certain whether dinosaurs were thriving or declining before the impact event. Some scientists propose that the meteorite caused a long and unnatural drop in Earth's atmospheric temperature, while others claim that it would have instead created an unusual heat wave.
Although the speed of extinction cannot be deduced from the fossil record alone, various models suggest that the extinction was extremely rapid. The consensus among scientists who support this theory is that the impact caused extinctions both directly (by heat from the meteorite impact) and also indirectly (via a worldwide cooling brought about when matter ejected from the impact crater reflected thermal radiation from the sun).
In September 2007, U.S. researchers led by William Bottke of the Southwest Research Institute in Boulder, Colorado, and Czech scientists used computer simulations to identify the probable source of the Chicxulub impact. They calculated a 90% probability that a giant asteroid named Baptistina, approximately 160 kilometers (100 mi) in diameter, orbiting in the asteroid belt which lies between Mars and Jupiter, was struck by a smaller unnamed asteroid about 55 kilometers (35 mi) in diameter about 160 million years ago. The impact shattered Baptistina, creating a cluster which still exists today as the Baptistina family. Calculations indicate that some of the fragments were sent hurtling into earth-crossing orbits, one of which was the 10 kilometers (6 mi) wide meteorite which struck Mexico's Yucatan peninsula 65 million years ago, creating the Chicxulub crater (175 kilometers (110 mi)).[120]
A similar but more controversial explanation proposes that "passages of the [hypothetical] solar companion star Nemesis through the Oort comet cloud would trigger comet showers."[121] One or more of these comets then collided with the Earth at approximately the same time, causing the worldwide extinction. As with the impact of a single asteroid, the end result of this comet bombardment would have been a sudden drop in global temperatures, followed by a protracted cool period.[121]
Deccan Traps
Before 2000, arguments that the Deccan Traps flood basalts caused the extinction were usually linked to the view that the extinction was gradual, as the flood basalt events were thought to have started around 68 Ma and lasted for over 2 million years. However, there is evidence that two-thirds of the Deccan Traps were created in 1 million years about 65.5 Ma, so these eruptions would have caused a fairly rapid extinction, possibly a period of thousands of years, but still a longer period than what would be expected from a single impact event.[122][123]
The Deccan Traps could have caused extinction through several mechanisms, including the release of dust and sulphuric aerosols into the air which might have blocked sunlight and thereby reducing photosynthesis in plants. In addition, Deccan Trap volcanism might have resulted in carbon dioxide emissions which would have increased the greenhouse effect when the dust and aerosols cleared from the atmosphere.[123] Before the mass extinction of the dinosaurs, the release of volcanic gasses during the formation of the Deccan traps "contributed to an apparently massive global warming. Some data point to an average rise in temperature of 8 °C (14 °F) in the last half million years before the impact [at Chicxulub]."[122][123]
In the years when the Deccan Traps theory was linked to a slower extinction, Luis Alvarez (who died in 1988) replied that paleontologists were being misled by sparse data. While his assertion was not initially well-received, later intensive field studies of fossil beds lent weight to his claim. Eventually, most paleontologists began to accept the idea that the mass extinctions at the end of the Cretaceous were largely or at least partly due to a massive Earth impact. However, even Walter Alvarez has acknowledged that there were other major changes on Earth even before the impact, such as a drop in sea level and massive volcanic eruptions that produced the Indian Deccan Traps, and these may have contributed to the extinctions.[124]
Failure to adapt to changing conditions
Lloyd et al. (2008) noted that, in the Mid Cretaceous, the flowering angiosperm plants became a major part of terrestrial ecosystems, which had previously been dominated by gymnosperms such as conifers. Dinosaur coprolites—fossilized dung—indicate that, while some ate angiosperms, most herbivorous dinosaurs mainly ate gymnosperms. Statistical analysis by Lloyd et al. concluded that, contrary to earlier studies, dinosaurs did not diversify very much in the Late Cretaceous. Lloyd et al. suggested that dinosaurs' failure to diversify as ecosystems were changing doomed them to extinction.[35]
Possible Paleocene survivors
Main article: Paleocene dinosaurs
Nonavian dinosaur remains are occasionally found above the K-T boundary. In 2002, paleontologists Zielinski and Budahn reported the discovery of a single hadrosaur leg bone fossil in the San Juan Basin, New Mexico and described it as evidence of Paleocene dinosaurs. The formation in which the bone was discovered has been dated to the early Paleocene epoch approximately 64.5 million years ago. If the bone was not re-deposited into that stratum by weathering action, it would provide evidence that some dinosaur populations may have survived at least a half million years into the Cenozoic Era.[125] Other evidence includes the finding of dinosaur remains in the Hell Creek Formation up to 1.3 meters (51 in) above (40000 years later than) the K-T boundary. Similar reports have come from other parts of the world, including China.[126] Many scientists, however, dismiss the " aleocene dinosaurs" as re-worked, i.e. washed out of their original locations and then re-buried in much later sediments,[127][128] or find that, if correct, the presence of a handful of dinosaurs in the early Paleocene would not change the underlying facts of the extinction.[127]
