GRE閱讀文章題源在哪裏
很多考生對GRE閱讀的文章來源有興趣，紛紛猜測GRE閱讀理解中的文章出處。不管怎麼說，考生若是能夠知道這些文章的出處對考生的閱讀複習將很有幫助。在此就爲考生講講GRE考試閱讀文章是怎麼來的。
GRE閱讀文章題源在哪裏?
1. 蒐集“源文章”
出題機構一般有自己固定的信息源和蒐集信息的渠道。如ETS使用一個名爲Source Finder的軟件在Internet上自動檢索數字論文庫EBSCO中的文獻，並從中提煉出符合各種考試風格要求(比如GRE和TOEFL等)的樣本GRE閱讀文章。
2. 加工改寫
出於版權限制，ETS用於實際的新GRE閱讀考試的文章長度最多隻能引用10%的原文長度。這種“帶着鐐銬跳舞”的結果是大量文章內容被改寫，重寫和刪節。改寫一般會大量使用分詞及從句，使句子變得更緊湊、更嚴密。儘管改寫後的文章會變得錯綜複雜，但出題機構會盡量保持文章中原有的鮮明態度以及較好的層次結構。如：文章一開始給出一個老觀點，後來有人提出新觀點，駁斥老觀點，文章作者對這個新觀點或完全同意、或持部分保留意見、或是做出有正有負的混合評價。
3. 設置出題點
出題機構一般會先出關於文章主題、套路、態度、結構以及與文章的主題有關的問題，再針對文中比較明確的內容出題。在出題方式上求新求變，一般會將原文中出現的詞彙或句子換一種說法表達出來。最後再找一些極易被考生忽略的細節作爲出題對象，以此提高考試難度，拉開考生的分數。
4.題材廣泛，不拘一格
如前言中所說，GRE閱讀理解的文章所涉及的題材有所區別，即GRE考試閱讀沒有管理類的文章，而這正是新GRE閱讀經常出現的題材。但總的來說，它們所涉及的題材都十分廣泛。
一般來說，GRE閱讀文章可分爲以下四類：人文類文章 (humanities)，自然科學類 (science)，社會科學類 (social science) 和商業管理類 (business)。
從GRE閱讀文章選擇可以看出，儘管GRE考試閱讀文章涉及的學科衆多，對這些雜亂的學科無需具備相應的知識，答案的重點均可在文章中找到。尊重新GRE閱讀文章的字句，不自己杜撰、屏蔽信息，這個就是可以做出完美GRE閱讀理解的重點。
GRE閱讀提分有哪些備考方法需要學習?這6個要點需要了解
新GRE閱讀提高方法解析：熟悉考點
新GRE考試閱讀首先要熟悉常考考點。俗化說，知己知彼，百戰百勝。要想迅速攻克新GRE閱讀難關，就要了解出題者的思維。根據題目反推原文考點，題目都考了原文哪些內容，自己有沒有關注到這些內容並做標記，這些內容都有什麼可總結的規律、特徵詞。這樣總結非常重要，如果堅持下去，很短一段時間後，就會發現一些固定的原文出題點，日後再讀原文的時候也就會自然而然地關注它們了。
新GRE閱讀提高方法解析：充足的詞彙
GRE閱讀部分所需掌握的單詞想比整個GRE考試對於考生詞彙量上的要求來講，其實並不太大。這些詞往往都是一些GRE閱讀專屬詞彙，且重複率很高，只需要在平時練習時多積累總結，集中背誦一下就可以解決基本問題。
新GRE閱讀提高方法解析：提高閱讀質量
提高新GRE閱讀其實說得細緻點就是提高几種具體的技能，比如對文章結構的把握(這是做主旨題和態度題的關鍵)，對常考新GRE考試考點的熟悉程度，對原文和選項之間的文字對應規律的掌握等。GRE閱讀理解高分突破如果只是一味地做題，沒有針對所需掌握地知識點和技能進行總結和積累，那麼做題的目的只是一味的爲了趕進度，對於提高沒有任何幫助。因此，在做新GRE考試閱讀練習的時候，不要盲目地追求閱讀的數量，要真正提高新GRE閱讀的質量。
新GRE閱讀提高方法解析：提高理解能力
GRE閱讀有很多閱讀技巧，但本質和基礎還是對於句子的理解能力。首先要對文章的大意甚至對一些具體的內容有一定的理解的基礎上，這些技巧才能發揮作用。所以，提高對於閱讀中句子的理解能力是備考過程中需要特別留意的。
新GRE閱讀提高方法解析：無需完整閱讀全文
要靠讀懂全文來做對題，對中國考生來說是一件很難的事情，即使把文章全部翻譯成中文，也很難在如此短的時間內逐字逐句理解全文，更何況是生詞連篇、複雜難懂的英文，所以我們要靠快速讀文法，學會抓重點。
新GRE閱讀提高方法解析：堅持練習
新GRE考試閱讀是一個長期的過程，不是說練習幾天就會有效果的。哪怕你的方法是正確的，可能短期效果也不是很明顯。所以，這個時候是最關鍵的時候，往往離勝利就在一步之間，堅持住可能就會豁然開朗。

長篇閱讀
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.
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.
Second, Jupiter's enormous mass prevents most Sun-bound comets from penetrating the inner solar system. 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.
Third, the gravitational shield of the giant outer planets, while highly efficient, must occasionally fail to protect Earth. 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.
1. The passage is primarily concerned with
A. Enumerating conditions that may have been necessary for a particular development
B. Outlining the conditions under which scientists may be able to predict certain events
C. Explaining how a particular finding affected scientists ' understanding of a phenomenon
D. Suggesting reasons why a particular outcome was more likely to occur than other possible outcomes
E. Assessing the relative significance of factors that contributed to a particular occurrence
答案：C
解析：
根據文章第一段內容，可知推出了一個finding，後面都是具體介紹這個發現的，所以圍繞的中心是C。
2. It can be inferred from the passage that the "planetary scientists" would be most likely to agree with which of the following statements concerning the development of complex life forms on Earth?
A. It might have occurred earlier in Earth's history if cometary impacts had been less frequent than they were.
B. It could have occurred if Earth's orbit were 1 percent larger than it is but not if Earth's orbit were 5 percent smaller.
C. It probably follows a pattern common on other terrestrial planets that occupy planetary systems containing gas giants.
D. Its dependence on the effect that Jupiter's gravitational shield has on Earth was difficult to recognize prior to 1995.
E. It has been contingent on conditions elsewhere in Earth's solar system as well as on conditions on Earth itself.
答案：E
解析：
題幹問planetary scientists 最有可能同意哪個觀點，而且是與the development of complex life forms on Earth有關，定位至第二段開頭處開始閱讀，運用排除法得出答案。
3. The author of the passage most likely mentions Mars' "oscillating tilt" primarily in order to
A. Provide evidence for a proposition about the potential effects of cometary impacts
B. Emphasize the absence from our solar system of "normal planets"
C. Contrast the rotational axis of Mars with that of Venus
D. Characterize the role of other planets in the solar system in earth's development
E. Emphasize the importance of the Moon to the development of life on Earth
答案：C
解析：
題幹問爲何提及Mars會震盪傾斜，定位至最後一段會發現後文提及了Venus與Mars是相反的，因此答案選C。
