GRE作文提分3大主要难点和应对策略介绍

GRE作文成绩的重要性

新GRE作文总分为6分,在总共346分的分数构成中看似不起眼,却是影响申请成功率的重要因素。如果能在作文中取得高分甚至满分的成绩,对于提高申请成功率有着巨大的帮助,特别是申请文科类研究生的考生,GRE作文分数的高低直接体现出了你对英语的掌握和综合运用能力,是各大研究生院入学申请参考审核的重要标准。

GRE作文难点详解

1.考试题材的广度及深度

GRE作文考试题目涉及广泛,遍及人文、历史、哲学、社会学科的众多领域,要求考生具备较宽广的知识面及较强的材料分析能力。对于不少闭门造车,只关注考试缺乏课外阅读量的同学来说会是一个巨大的挑战。

2.逻辑分析能力要求高

GRE作文考试中这方面体现得尤其突出,不仅要求作文词汇和语法的正确性,更看重考生在写作过程中从文章框架,论述结构等多个方面体现出的逻辑思维和分析的能力,行文构思能力不足的考生在面对GRE写作考试时可能会遇到不小的困难。

3. 迅速准确的分析能力

GRE作文要求在限定的时间内完成论点的提炼、论据的选择及文案架构的设计,并最后形成论点清晰、逻辑严密的文章。两篇文章总计1小时,每篇30分钟的时间要求还是比较严格的,要做到又快又好的写出一篇优秀作文,对考生的整体写作能力是一项考验。

GRE作文应对策略

对于上述的这些难点,正对性的进行一些应对准备,还是会对提高分数有不小的帮助。

1. 拓宽知识面,培养材料分析能力

需要考生在平时不要只看题目埋头做题,多补充一些各个领域的知识,拓宽自己的知识面,多涉猎不同的学科,进行知识的累积和储备,在这个过程中也要随时注意对手头阅读材料的分析能力的培养,不要看过就算,而是仔细思考其中隐含的可能考点,做好准备,养成勤于思考的习惯。

2. 提高逻辑分析能力

逻辑分析能力的提升不是朝夕可成的,需要一定的阅读量和练习的积累才能逐渐提高,建议大家在平时的备考训练过程中对于阅读题目加强逻辑思维方面的分析工作,多总结别人的文章是怎么写的,如何进行逻辑论证,同时也可以通过阅读逻辑方面的书籍以及练习题来进行提高。

3. 提高写作效率

同样是需要大量练习的备考工作,平时写作文时,不仅要注重文章质量,更要对练习的完成时间提出高要求,每次写文章都按照考试要求计算时间,强迫自己适应考试的时间节奏,培养出高效的写作分析能力,在平常的练习中要刻意加强快速思辨及准确表达能力的训练,养成有条理、逻辑形文的习惯。

以上就是关于GRE作文难点的详解和应对策略的介绍,希望能对大家的GRE作文备考有所帮助。

GRE Issue写作范文详细解析

Topic

The following is a letter to the editor of an environmental magazine:“The decline in the numbers of amphibians worldwide clearly indicates the global pollution of water and air. Two studies of amphibians in Yosemite National Park in California confirm my conclusion. In 1915 there were seven species of amphibians in the park, and there were abundant numbers of each species. However, in 1992 there were only four species of amphibians observed in the park, and the numbers of each species were drastically reduced. The decline in Yosemite has been blamed on the introduction of trout into the park"s waters, which began in 1920 (trout are known to eat amphibian eggs). But the introduction of trout cannot be the real reason for the Yosemite decline because it does not explain the worldwide decline.”

Sample Essay

In this argument, the writer of the letter concludes that global pollution of water and air has caused a decline in the number of amphibians worldwide. To support his or her conclusion, the writer cites the results of two studies, seventy-five years apart, that purportedly show that the number of amphibians in one park in California, Yosemite National Park, have drastically declined. Additionally, the writer casts aside a given reason for the decline, stating that the introduction of trout to the park (who are known to eat amphibian eggs) does not explain the worldwide decline in the number of amphibians. This argument defies simple logic and suffers from several critical fallacies.

First of all, the argument is based on only two studies in one specific part of the world, Yosemite National Park in California. It is impossible to pinpoint a worldwide theory for the decline of amphibians based on any number of studies in only one specific location in the world - the specific varieties of amphibians, geographical conditions and other location specific variables prohibit such a sweeping generalization. One very specific location cannot be used as a model for all other locations, even within one particular country, let alone the entire world. The writer provides no evidenced whatsoever that links the Yosemite study with any purported effects anywhere else in the global environment.

Secondly, the two separate studies were done seventy-five years apart. There is no evidence that the two studies were conducted in a similar manner over the same duration of time or even over the same exact areas of Yosemite National Park, or that the exact same study methods were used. For example, perhaps the first study lasted over an entire year and was conducted by twenty-five experts in amphibious biology, resulting in the finding of seven species of amphibians in abundant numbers. By contrast, perhaps the second study was conducted over a period of one week by a lone high school student as a school science project. The writer offers no basis on which to compare the two studies, leaving it open as to whether the two are truly comparable in their breadth, scope and expertise.

Finally, the writer notes that the decline in the amphibian population has been blamed on the introduction of trout into the park"s waters in 1920, but then dismisses that argument on the purely specious basis that it does not explain the worldwide decline. This part of the argument blithely dismisses the very relevant fact that trout are known to eat amphibian eggs. This attempt to “prove a negative” is the last resort of those in search of some vain attempt to prove the truth of the matter that they are asserting. It is basically impossible to “prove a negative”; this is an attempt to shift the burden of proof back on to the nonbelievers of the argument. The global environmental situation and that of Yosemite National Park are not perfectly correlated, and the fact that the trout may very well be responsible for the decline cannot simply be dismissed without further proof.

In summary, the writer fails to establish any causal relationship between global air and water pollution and the decline of amphibious life worldwide. The evidence presented is extremely weak at best and narrowly focuses on one tiny area of the globe, as well as putting forward as proof two studies about which almost nothing is known. For a stronger argument, the writer would need to directly put forth evidence associating air and water pollution with not only the decline at Yosemite but also throughout other areas of the world.(599 words)

[题目]

下述文字摘自一封致某环保杂志编辑的信函:“全球两栖动物数量的减少明显标志着全球性水与大气的污染。对加利福尼亚州约塞米蒂国家公园内两栖动物所作的两项研究可证实我的这一结论。19公园内有七个物种的两栖动物,每一物种都拥有丰富的种群数量。然而,1992年,在公园内所能观察到的两栖动物物种仅为四类,且每一物种的种群数量已骤然下降。约塞米蒂公园动物数量减少被归咎于始于19的将鲑鱼引入公园水域的做法(众所周知,鲑鱼喜食两栖动物所产的卵)。但鲑鱼的引入不可能成为约塞米蒂公园动物数量减少的真正原因,因为它无法来解释全球范围内的动物数量减少。”

[范文正文]

在本项论述中,信函作者的结论是,全球性水与大气污染已致使世界范围内两栖动物的数量减少。为了支持其论点,作者援引了两份时隔75年之久的研究结果,这两份结果据称可证明加利福尼亚州某一公园――即约塞米蒂国家公园――内两栖动物的数量锐减。此外,该作者撇开了动物数量减少的一个已知原因,陈述道,将鲑鱼引入公园(据称,鲑鱼喜食两栖动物所产的卵)这一做法不足以解释世界范围内两栖动物数量上的减少。这一论点有悖于简单的逻辑,犯有一系列关键性的逻辑谬误。

首先,该论点所依据的仅仅是世界上某一特定地点――即加利福尼亚州约塞米蒂国家公园――内的两份研究。围绕着两栖动物数量减少这一问题,如果仅以世界上一个特定的地点为样品,再多数量的研究也无法得出一种精确的、适用于全世界的理论。两栖动物的具体种类、地理状况以及其他因地点而特异的变数均不允许我们作出如此一概而论的总括。一个非常具体的地点不能用作一个代表所有其他地点的模型,即使在一个特定的国家内也不行,更不用说在整个世界范围内了。信函作者没有提供任何证据将约塞米蒂公园的研究与全球环境中任何其他一处地方的任何所宣称的效果联系起来。 其次,所提及的那两项互为独立的研究时隔75年之久。没有证据可证明这两项研究是在相同的时间跨度内以相似的方式进行的,或是在约塞米蒂公园完全相同的地点进行的,或所使用的研究方法绝然相同。

例如,第一项研究可能持续了整整一年之久,且是由两栖动物生物学领域的二十五位专家共同进行的。结果是发现了七大种类数目众多的两栖动物。相反,第二项研究可能是一位高中生孤身一人所做的学校的一个科学课题,仅为期一个星期。信函作者没有提供将此两项研究进行比较的基础,从而使两项研究在其广度、范围以及专业水准方面的可比性不得而知。 最后,信函作者指出,两栖动物种群数量的减少,已被人归咎于1920年将鲑鱼引入公园水域这一做法,但紧接着又以该论据无法解释世界范围内动物数量减少这一似是而非的依据将该论据予以否认。信函作者论述中的这一部分漫不经心地将一个极为相关的事实弃置不顾,即众所周知,鲑鱼喜食两栖动物所产的卵。这种“prove a negative ”的尝试往往是这样一类人所惯用的最后伎俩,他们竭力寻找某种徒劳的尝试,力图去证明他们所宣称的事物的真理。从根本上讲,“prove a negative”是不可能的。这样一种做法是试图将论证的负担重新转嫁给不相信该论据的人。全球的环境情形与约塞米蒂公园的情形并不绝然对应。鲑鱼极有可能造成了两栖动物数量减少这一事实在缺乏进一步证据的情况下是断不能轻易予以否认的。

概括而言,信函作者没能在全球空气和水污染与世界范围内两栖生命数量减少之间建立起任何因果关系。该作者所拿出的证据充其量也是极为苍白无力的,狭隘地将焦点集中在世界的一片极小的区域上,作为证据而援引的两项研究几乎不能说明任何问题。欲使其论点更具力度,信函作者尚需摆出直接的证据,将水和空气污染不仅仅与约塞米蒂公园的两栖动物数量减少联系起来,而且也与世界其他地方的动物数量减少联系起来。

上文的内容非常详细,大家要好好利用它们,切忌生搬硬套,祝大家考出好成绩。

GRE优秀作文范例参考

正文:

Nowadays there is a growing concern about the role that innovations have played in the field of learning. While most people think that innovations benefit learning process in various ways,different opinions arise that these technology advancements actually distract students from real learning. On balance,according to my personal observation,whether innovations can be beneficial or detrimental to real learning depends on the students and the teachers,not on these innovations themselves.

To begin with,technological innovations do help teaching and learning in various ways.With the aid of these technologies,the process of teaching and learning can be shorter and easier than before. For instance,if a student want certain published papers of an academic discipline,he/she may look through considerable catalogs to find the ones he/she needs. However,with the help of Internet innovation,at present most of these papers are published online. Consequently,to find certain paper the procedure is much easier and shorter,the students just type the key words and other information of the paper,and then the system will search the database,and the papers are there waiting for them. As this new approach can save a lot of time for the students,he/she could have more time reading the papers and absorbing the knowledge rather than checking and looking for the papers that could be a waste of his/her time. This example aptly illustrates how technology advancement benefited the students and their learning process.

Secondly,while innovations can help learning in various ways,it is more important that the central role of the pursuit for knowledge and wisdoms are maintained. What real matters is not the approach but the purpose of learning. In India,where modern technologies are less applied to the learning process than in the US and other developed countries,still a lot of distinguished students achieved their academic goal with their hard work and desires to knowledge. In the US,where the software engineering students are given the most advanced facilities and apparatus for their learning and research,however,it is wildly accepted that they are far less outstanding compared to the Indian students of software,who may share computers in groups. From this comparison we can see that the real and core push of learning is the desire for knowledge,not the help of innovations.

In addition,if not guided properly,the technology advancement might inhibit learning.In other words,innovation can distract the students from real learning than helping them. It is obvious that a computer can help students of science to calculate mathematical equations but can also be used for recreation such as net surfing or computer games. It is highly possible that these students can spend more time and energy on recreations rather than learning when using a computer. Thus,learning is inhibited. Under this circumstance,guidance and restrictions are needed to ensure the right use of innovations for learning,or the consequence may be on the contrary to the students and teachers" desire.

To conclude,technological innovations are beneficial to learning in many ways,but when using these technologies,one should not forget the real purpose of learning and remember not to be distracted for other usages of these innovations that are irrelevant or detrimental to learning. On balance,innovation here serves as a double-edges sword,and its right use is dependent on the students and the teachers.

GRE数学机经提分用法完全解读

第3篇: GRE作文机经高效率提分用法

GRE作文提分从重视细节开始 关注这4个写作要点高分更有把握

时间安排

GRE写作要求考生在2个30分钟的限制时间段内分别完成一篇ARGUMENT文章和一篇ISSUE文章的写作,考生需要在30分钟内完成从读题审题到写完全文的工作,时间上的要求可谓相当紧迫。为了在短暂的时间内写出优质的文章,考生需要学会合理安排写作的时间,用多少时间看题、构思、列提纲、写文章。每个环节都需要进行详细的安排并通过备考进行练习,把时间管理和控制能力练好。

文章字数

GRE写作字数虽然没有明确的规定,但一般建议还是应至少在400字以上为佳,字数太少,往往意味着没有进行足够充分的论述,会给考官留下考生没有管理好写作时间,或者缺乏写作能力的印象,最终得分一般也不会太高。当然字数过多,但满篇都是凑字数的废话空话,也同样会影响得分。所以如果能够在保证进行充分论述的基础上,把字数控制在400-600字之间,往往是比较合适的。

机经真题

GRE考试是非常系统而且专业的语言水平测试,它有着庞大的题库,有些题目也会重复出现,所以考生可以通过了解官方作文题库和以往考题,对题目的类型和内容进行充分把握,为考试做好充分准备。当然,对于预测性的机经,比如下场考试会出现什么题型,建议大家还是应谨慎对待,不要抱有投机心理,应该以提升自身写作实力为重。

文体注意事项

让我们通过具体的例子来了解此类文章书写和文体的特点

1. N2O wasn"t produced until 1990, after which, its production grew rapidly.

GRE文章为正式文体,所以尽量不要出现缩写,wasn"t建议写成was not 。

2. The bottles are first divided by color into clear, brown and clear ones which are then washed by high-pressurised water.

拼写出现问题。在GRE写作中,英式和美式拼写都接受,但小编建议考生还是尽量做到两者不混淆。如or和our,se和ze。or和ze为美式拼写,而our和se为英式拼写。

3. Nowadays, more and more people have private cars.

more and more词汇过于简单,我们可以用an increasing number of来替代。

4. Let all of us make great efforts to construct a more civilised China!

此句子喊口号,抒发情感。GRE两篇作文为立论和驳论类文章,不需要任何形式的情感抒发和口号,所以这句话不适合这样的语言环境。

细节决定成败,GRE作文考试也是如此,大家在备考时,不仅需要努力提升自身写作水平,也应该对上文提及的各类高分细节多加注意,如此,才能确保在考场上万无一失的发挥出自身实力,取得作文高分。

GRE作文提分从重视细节开始

第4篇: GRE作文机经高效率提分用法

GRE阅读考前刷机经能冲刺提分

GRE阅读机经提分作用好?

GRE阅读机经如果使用得当,可以对于GRE考试成绩有一定程度的提高。如果是一个水平不高的GRE考试者,利用机经则有可能使你的成绩轻松提高数十分,即使是高手也能有稳定情绪节约时间的效果。GRE阅读机经是通过对机经的回忆而整合出来的资料库性质的复习材料。既然是机经回忆,研究GRE阅读机经肯定会对熟悉考试内容有所帮助。

但是,GRE阅读机经毕竟是靠回忆得来的资料,难免会存在一些误差和失真,比如题目的不完整,答案也因人而异,值得商榷和斟酌。由于GRE题库中题目的会重复出现,所以在考场上看到阅读机经的几率是大大存在的。

GRE阅读机经提分要这么刷

小编需要特别提醒大家的是,不建议考生完全依赖于GRE机经备考,更不能只靠死背记住机经答案就觉得考试万无一失了。考生还是应该以理解题目、熟悉出题思路和解答方法作为主要突破口进行机经的学习和研究。具体来说,考生看阅读机经,主要还是了解一下文章所讲的内容,对于题目会考到的一些细节留意其原文所在位置,还有主旨题态度题等涉及到的相关内容也要留下一定影响。但大家千万不要花功夫去把具体每道题目选哪个选项都背下来,因为考试中即使遭遇到也很少会原样照搬。如果只是死记硬背下了答案,考试题目稍稍做些改动就可能会让你反受其害,所谓机经反噬正是如此。

认清机经价值才能发挥提分作用

虽然GRE阅读机经会为你的备考带来一定的便利,但正如很多GRE老师和考生都总结过的,GRE机经可以帮你,但救不了你。GRE考试说到底还是考察考生的综合实力,如果底子打不好,基础不扎实,想要靠着机经投机取巧搞定考试是不现实的。同学们还应该以平时的备考练习为主,脚踏实地的积累实力,为考试做好充分的准备,在这个基础上学习参考GRE阅读机经,才能让其发挥出最大的价值。

GRE阅读真题

The more definitions a given noun has, the more valuable is each one. Multiple definitions, each subtly different from all the others, convey multiple shades of meaning. They expand the uses of the word; language is enriched, thought is widened, and interpretations increase or dilate to fill the potentialities of association. The very impossibility of absoluteness in the definition of certain nouns adds to the levels of connotation they may reach. The inner life of a writer often says more than most readers can know; the mind of a reader can discover truths that go beyond the intent or perhaps even the comprehension of the writer. And all of it finds expression because a word can mean many things.

1. In the context in which it appears, “shades” (line 2) most nearly means

A. reminders

B. nuances

C. obscurities

D. coverings

E. degrees

2. The passage suggests that a writer’s use of nouns that have multiple definitions can have which of the following effects on the relationship between writer and reader?

A. It can encourage the reader to consider how the writer’s life might have influenced the work.

B. It can cause the reader to become frustrated with the writer’s failure to distinguish between subtle shades of meaning.

C. It can allow the reader to discern in a work certain meanings that the writer did not foresee.

D. It allows the writer to provide the reader with clues beyond the word itself in order to avoid ambiguity.

E. It allows the writer to present unfamiliar ideas to the reader more efficiently.

GRE阅读:飞鼠寻找食物

The objective of this study was to evaluate how northern flying squirrels (Glaucomys sabrinus) locate truffles (Gautieria monticola), a subterranean and ephemeral but primary food source. Thus, we evaluated the importance of three factors to the foraging behavior of northern flying squirrels: (i) olfactory chemicals that emanate from truffles; (ii) the presence of coarse woody debris (decaying l.s), which are often associated with fungi; and (iii) we explored the potential role animal memory could play in truffle detection as well. In a foraging arena, squirrels successfully retrieved buried truffles that lacked aboveground cues in 19 of 30 trials and failed to search near treatments that lacked truffles alt.ether, confirming the importance of olfaction to squirrel foraging. However, squirrels also retrieved truffles that were associated most frequently with surface l.s (27 of 30). In addition, the initial detection rate of the truffle + l. treatment was significantly greater than the truffle-only treatment. Thus, although squirrels search for truffles primarily using olfaction, they may also benefit by searching near coarse woody debris on the forest floor as an aboveground cue to truffle locations. In addition, because 82% of Sierra Nevada truffle-fruiting locations that were marked in yielded truffles again the following 2 years, mycophagous animals like northern flying squirrels may benefit by memorizing fruiting locations and foraging at these same locations from year to year.

不要把机经当成投机取巧救命稻草

GRE阅读选择答案的具体技巧

阅读考查的范围非常广,不像填空、类比和反义那样注重基础和词汇量,而GRE阅读又与其他考试中的阅读有很大区别,所以在技巧方法上也要区分对待。GRE阅读中多见长句,对理解造成很大障碍,然而这一大特点也促使形成了解决GRE阅读的一个制胜法宝——从原文中来,到原文中去。因为长句具有较高的难度,所以出题者会把很大的精力放在对句子本身的理解上,而不像其他考试中的阅读那样主要侧重对文章内容的理解。在实际解题过程中,我们如果真正理解并掌握了这一点,就能提高做题速度和准确性,因为实实在在能从原文中找到证据的答案必定是正确答案。

虽然答案是绝对忠于原文的,但它的出现往往都披着迷惑人的外衣,同时其他四个似是而非的选项也会对考生进行干扰。对原文中句子变形的方法多种多样,变形后的句子所使用的句式和词组搭配常常不同于原句,一般会是对原句的解释和概括,但基本框架不变。一旦正确掌握了原句的复杂结构,选择出正确答案就不会困难了。以下几个例子都来自考生容易选错的题目:

Eg1. According to the passage, random failures in automatic control systems are “not merely trivial aberrations” because

(A) Automatic control systems are designed by engineers who have little practical experience in the field

(B) The failures are characteristic of systems designed by engineers relying too heavily on concepts in mathematics

(C) The failures occur too often to be taken lightly

(D) Designers of automatic control systems have too little training in the analysis of mechanical difficulties

(E) Designers of automatic control systems need more help from scientists who have a better understanding of the analytical problems to be solved before such systems can work efficiently

本题在原文中的定位为:Absurd random failures that plague automatic control systems are not merely trivial aberrations; they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics. 这个句子中间用分号隔开,分号前的部分对应着题干中的问题,分号后即是对前半句的解释,也就是说这个句子本身就是一问一答型,答案就是后半句话,在选择答案时我们只要看哪个选项是对这句话的变形即可。注意这半句话中chaos是一个关键词,that 引导定语从句,而这个定语从句中又有一个关键短语:result in,这个短语是表示结果的,然后看它的宾语是mathematics,而这个名词是不能被替换掉的,直接从五个选项中挑选,只有B说出了mathematics,无疑这就是正确答案了。解答本题时能看出mathematics这一重心之后,根本不需要自己进行任何总结和概括,看出哪个选项是对原句的变形就全部搞定了。我们再仔细看一下B答案,其中rely heavily on代替了原句中的chaos result in,而意义与先前保持一致。

Eg2. According to the passage, certain serious contemporary phot.raphers expressly make which of the following claims about their phot.raphs?

(A)Their phot.raphs could be created by almost anyone who had a camera and the time to devote to the activity.

(B)Their phot.raphs are not examples of art but are examples of the phot.raphers" impartial observation of the world.

(C)Their phot.raphs are important because of their subjects but not because of the responses they evoke in viewers.

(D)Their phot.raphs exhibit the same ageless principles of form and shading that have been used in painting.

(E) Their phot.raphs represent a conscious glorification of the mechanical aspects of twentieth-century life.

本题在原文中的定位为:Serious phot.raphers variously claim to be finding, recording, impartially observing, witnessing events, exploring themselves—anything but making works of art. 注意anything but 是“决不”的意思,B答案就是对这句话的变形,只不过是把原文中所列出的几种形式用examples概括罢了。在这个例子中还要注意的是原句中的anything but注定了其变形应该表示否定,按照这种理解很容易选出正确答案。

Eg3. According to the passage, what did Hargrave and Green do in the laboratory?

(A) They compared the grazing rates of individual zooplankton species in the laboratory with the natural grazing rates of these species.

(B) They hypothesized about the population density of grazers in natural habitats by using data concerning the population density of grazers in the laboratory.

(C) They estimated the community grazing rates of zooplankton in the laboratory by using data concerning the natural community grazing rates of zooplankton.

(D) They estimated the natural community grazing rates of zooplankton by using data concerning the known population density of phytoplankton.

(E) They estimated the natural community grazing rates of zooplankton by using laboratory data concerning the grazing rates of individual zooplankton species.

本题在原文中的定位为:Studies by Hargrave and Green estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers. 原句比较复杂,并且使用and then介绍操作顺序,在理解原句时要分清主要动作和次要动作,而选项中给出的句子都非常短,也就是要对原句进行压缩,找出主要动作。理解了这种变形之后,不难发现正确答案为E。

GRE阅读利用虚拟语气找答案

(1) 若在文章中看到虚拟语气,考虑直接取非反义理解,迅速把握作者态度。

如下面这句话:

例一:Perhaps, some scientists thought, migrants determine their ge.raphic position on Earth by celestial navigation, almost as human navigators use stars and plan, but this would demand of the animals a fantastic map sense. (选自N0.6题第一套section 1短文章)

这句话看似很长,翻译成为中文的意思是:“有些科学家认为,就像人类采用恒星和行星来定位一样,候鸟或许也是采用天体的导航才得以确定它们所处的地理位置,但这要求这类动物具有令人难以置信的地图感。”中文读过去都让人头疼。其实我们用虚拟语气取非的思想来处理,其要表达的意思就很简单,对前半句话取非,说白了就是前半句话是行不通的,也就是“migrants cannot determine their ge.raphic position on Earth by celestial navigation。”可以知道作者对这种解释持负评价。

我们再来看个例子:

例二:According to natural selection theory, a worker would enhance her fitness—or ability to propagate her genes—by hatching her own eggs in addition to or in place of the queen’s。(选自国内题1993年10月练习题section 5短文章)

这句话也是虚拟语气,我们直接取反理解,作者想要表达的就是 “a worker will not enhance her …”

运用这种取非的思想我们可以迅速的把握作者的态度,以及作者想要表达的真实意思。就不用先翻译成绕口的中文,再拼命的思索其中的含义,可以有效地为考试争取时间。

(2) 在题干中看到虚拟语气,大多需要用到取非思想,与之相对应的一种题型是GRE阅读题中常见的一种,叫做“改进型取非题”。看例子之前,先简单解释下什么是“改进型取非题”。很简单,如果题干问“如果一个对象怎样会更好”则是改进型取非题,来看具体的例子:

例:It can be inferred from the passage that the “first theories” of grazer control mentioned in line 3 would have been more convincing if researchers had been able to(选自NO.6第二套section 1长文章),这是一个典型的改进型取非题题干,问的是第三行第一个理论怎样会更好。

逻辑思路:既然是改进,原文肯定说到了它的不好之处或者有unless的句子,我们把造成不好的原因取非,就是所要的答案了。

按照此思路定位原文三行,看到后面有这样一句话“A low number of algal cells in the presence of a high number of grazers suggested, but did not prove, that the grazers had removed most of the algae。”注意看插入语部分的“but did not prove”,这个就是缺点,取非就是“prove”再看五个选项:

(A) observe high phytoplankton numbers under natural lake conditions

(B) discover negative correlations between algae and zooplankton numbers from their field research

(C) understand the central importance of environmental factors in controlling the growth rates of phytoplankton

(D) make verifiable correlations of cause and effect between zooplankton and phytoplankton numbers

(E) invent laboratory techniques that would have allowed them to bypass their field research concerning grazer control

一眼扫过去就只有一个选项在讲证明,就是D中的verifiable。所以答案选D。很快解完此题。

(3) 取非的思路除了可以在虚拟语气中使用,还可以在另一种逻辑关系中使用,就是强对比的关系,也就是GRE阅读题中另一种常练习题型“强对比互取非题”,其主要特点是:原文中有强对比的双方,题干只问及其中一方,答案是对另一方叙述的取非;或者题干和原文存在强对比要素,如典型的时间要素,答案也是对原文的叙述取非。

来看个简单的例子,

例:The author suggests that, before the early 1950’s, most historians who studied preindustrial Europe did which of the following(选自NO.6第三套section 4 长文章)

思路:在题干中看到了1950’s,第一反应就是要回原文定位,发现原文只讲到了”in the early 1950’s”并没有”before”,这显然就是时间上一个取非的关系,我们把in the early 1950’s干的事情取个非,就是之前干的事情。答案就很好选了,在此不举出来了。
