GRE阅读文章题源在哪里

　　很多考生对GRE阅读的文章来源有兴趣，纷纷猜测GRE阅读理解中的文章出处。不管怎么说，考生若是能够知道这些文章的出处对考生的阅读复习将很有帮助。在此就为考生讲讲GRE考试阅读文章是怎么来的。

　　GRE阅读文章题源在哪里?

　　1. 搜集“源文章”

　　出题机构一般有自己固定的信息源和搜集信息的渠道。如ETS使用一个名为Source Finder的软件在Internet上自动检索数字论文库EBSCO中的文献，并从中提炼出符合各种考试风格要求(比如GRE和TOEFL等)的样本GRE阅读文章。

　　2. 加工改写

　　出于版权限制，ETS用于实际的新GRE阅读考试的文章长度最多只能引用10%的原文长度。这种“带着镣铐跳舞”的结果是大量文章内容被改写，重写和删节。改写一般会大量使用分词及从句，使句子变得更紧凑、更严密。尽管改写后的文章会变得错综复杂，但出题机构会尽量保持文章中原有的鲜明态度以及较好的层次结构。如：文章一开始给出一个老观点，后来有人提出新观点，驳斥老观点，文章作者对这个新观点或完全同意、或持部分保留意见、或是做出有正有负的混合评价。

　　3. 设置出题点

　　出题机构一般会先出关于文章主题、套路、态度、结构以及与文章的主题有关的问题，再针对文中比较明确的内容出题。在出题方式上求新求变，一般会将原文中出现的词汇或句子换一种说法表达出来。最后再找一些极易被考生忽略的细节作为出题对象，以此提高考试难度，拉开考生的分数。

学习啦在线学习网　　如前言中所说，GRE阅读理解的文章所涉及的题材有所区别，即GRE考试阅读没有管理类的文章，而这正是新GRE阅读经常出现的题材。但总的来说，它们所涉及的题材都十分广泛。

　　一般来说，GRE阅读文章可分为以下四类：人文类文章 (humanities)，自然科学类 (science)，社会科学类 (social science) 和商业管理类 (business)。

　　从GRE阅读文章选择可以看出，尽管GRE考试阅读文章涉及的学科众多，对这些杂乱的学科无需具备相应的知识，答案的重点均可在文章中找到。尊重新GRE阅读文章的字句，不自己杜撰、屏蔽信息，这个就是可以做出完美GRE阅读理解的重点。

　　GRE阅读提分有哪些备考方法需要学习?这6个要点需要了解

学习啦在线学习网　　新GRE阅读提高方法解析：熟悉考点

　　新GRE考试阅读首先要熟悉常考考点。俗化说，知己知彼，百战百胜。要想迅速攻克新GRE阅读难关，就要了解出题者的思维。根据题目反推原文考点，题目都考了原文哪些内容，自己有没有关注到这些内容并做标记，这些内容都有什么可总结的规律、特征词。这样总结非常重要，如果坚持下去，很短一段时间后，就会发现一些固定的原文出题点，日后再读原文的时候也就会自然而然地关注它们了。

　　新GRE阅读提高方法解析：充足的词汇

学习啦在线学习网　　GRE阅读部分所需掌握的单词想比整个GRE考试对于考生词汇量上的要求来讲，其实并不太大。这些词往往都是一些GRE阅读专属词汇，且重复率很高，只需要在平时练习时多积累总结，集中背诵一下就可以解决基本问题。

　　新GRE阅读提高方法解析：提高阅读质量

　　提高新GRE阅读其实说得细致点就是提高几种具体的技能，比如对文章结构的把握(这是做主旨题和态度题的关键)，对常考新GRE考试考点的熟悉程度，对原文和选项之间的文字对应规律的掌握等。GRE阅读理解高分突破如果只是一味地做题，没有针对所需掌握地知识点和技能进行总结和积累，那么做题的目的只是一味的为了赶进度，对于提高没有任何帮助。因此，在做新GRE考试阅读练习的时候，不要盲目地追求阅读的数量，要真正提高新GRE阅读的质量。

学习啦在线学习网　　新GRE阅读提高方法解析：提高理解能力

　　GRE阅读有很多阅读技巧，但本质和基础还是对于句子的理解能力。首先要对文章的大意甚至对一些具体的内容有一定的理解的基础上，这些技巧才能发挥作用。所以，提高对于阅读中句子的理解能力是备考过程中需要特别留意的。

学习啦在线学习网　　新GRE阅读提高方法解析：无需完整阅读全文

学习啦在线学习网　　要靠读懂全文来做对题，对中国考生来说是一件很难的事情，即使把文章全部翻译成中文，也很难在如此短的时间内逐字逐句理解全文，更何况是生词连篇、复杂难懂的英文，所以我们要靠快速读文法，学会抓重点。

　　新GRE阅读提高方法解析：坚持练习

　　新GRE考试阅读是一个长期的过程，不是说练习几天就会有效果的。哪怕你的方法是正确的，可能短期效果也不是很明显。所以，这个时候是最关键的时候，往往离胜利就在一步之间，坚持住可能就会豁然开朗。

　　GRE阅读机经权威汇总 应对长阅读难题要这么做

　　长篇阅读

　　In 1995 the Galileo spacecraft captured data about Jupiter's atmosphere--namely, the absence of most of the predicted atmospheric water--that challenged prevailing theories about Jupiter's structure. The unexpectedness of this finding fits a larger pattern in which theories about planetary composition and dynamics have failed to predict the realities discovered through space exploration. Instead of "normal planets" whose composition could be predicted by theory, the planets populating our solar system are unique individuals whose chemical and tectonic identities were created through numerous contingent events. One implication of this is that although the universe undoubtedly holds other planetary systems, the duplication of the sequence that produced our solar system and the development of life on Earth is highly unlikely.

学习啦在线学习网　　Recently planetary scientists have suggested that the external preconditions for the development of Earth's biosphere probably included four paramount contingencies. First, a climate conducive to life on Earth depends upon the extraordinarily narrow orbital parameters that define a continuously habitable zone where water can exist in a liquid state. If Earth's orbit were only 5 percent smaller than it is, temperatures during the early stages of Earth's history would have been high enough to vaporize the oceans. If the Earth-Sun distance were as little as 1 percent larger, run away glaciations on Earth about 2 billion years ago would have caused the oceans to freeze and remain frozen to this day.

It has been estimated that without this shield, Earth would have experienced bombardment by comet-sized impactors a thousand times more frequently than has actually been recorded during geological time. Even if Earth's surface were not actually sterilized by this bombardment, it is unlikely that any but the most primitive life-forms could have survived. This suggests that only planetary systems containing both terrestrial planets like Earth and gas giants like Jupiter might be capable of sustaining complex life-forms.

Paradoxically, while the temperatures required for liquid water exist only in the inner solar system, the key building blocks of life, including water itself, occur primarily beyond the asteroid belt. Thus the evolution of life has depended on a frequency of cometary impacts sufficient to convey water, as well as carbon and nitrogen, from these distant regions of the solar system to Earth while stopping short of an impact magnitude that would destroy the atmosphere and oceans.

　　Finally, Earth's unique and massive satellite, the Moon, plays a crucial role in stabilizing the obliquity of Earth's rotational axis. This obliquity creates the terrestrial seasonality so important to the evolution and diversity of life. Mars, in contrast, has wildly oscillating tilt and chaotic seasonality, while Venus, rotating slowly backward, has virtually no seasonality at all.
