GRE阅读主题句怎么找?快速定位心得分享

GRE阅读中主题句常见形式

和国内学生写文章不一样，美国人的阅读文章中从来都不出现“I think that，in my opinion，as far as I am considered”此类语言做主题句。通常来说主题句有以下两种形式：

1. 判断句(含情态动词，系动词，正负褒贬词的句子);

2. 概括文章将来结构。

实例讲解主题句定位方法

以这句话为例：Your minds changed my attitude. 这句话中并没有情态动词和系动词，因此这句话自然不是判断句，也就不是主题句。但只要在这句话中加入一个正负褒贬词，即一个词表明作者的态度或观点的词即是判断句了。比如，Your minds successfully changed my attitude即是判断句了。

另外，如果一个句子不是判断句，只要它能够概括文章将来结构，及文章后面会从哪几个方面来说明，也是主题句。比如，People are living longer now. 这句话一定不是主题句，而如果这句话是，People are living longer now since the improvement of food condition and the development of medical technology.这句话即是主题句了。因为它概括了文章后面会从哪几个方向来进行说明。

学会快速定位主题句的实用价值

如果考生在新GRE阅读题中掌握好了主题句判断方法，很多文章便可以很快把握文章的结构框架，帮助后面文章的理解。

比如一篇文章的开头是，Mycorrhizal fungi infect more plants than do any other fungi and are necessary for many plants to thrive， but they have escaped widespread investigation until recently for two reasons. First， the symbiotic association is so well-balanced that the roots of host plants show no damage even when densely infected. Second， the fungi cannot as yet be cultivated in the absence of a living root.

第一句是明显的判断句，即为主题句。而主题句也同时概括了文章的将来结构，即会从“M真菌影响力很强”和“M真菌过去由于两个原因没有得到广泛研究”。下面马上看到了first和second，我们即知道这两个很难读懂的句子无非是两个原因使得M真菌没有得到广泛研究而已，具体是哪两个原因，我们几乎可以忽略不读。

综上所述，在做GRE阅读时，快速定位主题句的方法和技巧是非常实用的，希望大家都能学会掌握和运用这种技巧，提高选对选项的效率，节省考试时间。

GRE阅读例题：遥感技术的前世今生

The age at which young children begin to make moral discriminations about harmful actions committed against themselves or others has been the focus of recent research into the moral development of children. Until recently, child psychologists supported pioneer developmentalist Jean Piaget in his hypothesis that because of their immaturity, children under age seven do not take into account the intentions of a person committing accidental or deliberate harm, but rather simply assign punishment for transgressions on the basis of the magnitude of the negative consequences caused.

However, in recent research, Keasey found that six- year-old children not only distinguish between accidental and intentional harm, but also judge intentional harm as naughtier, regardless of the amount of damage produced. Both of these findings seem to indicate that children, at an earlier age than Piaget claimed, advance into the second stage of moral development, moral autonomy, in which they accept social rules but view them as more arbitrary than do children in the first stage. (163 words)

8.According to the passage, Piaget and Keasey would not have agreed on which of the following points?

(A) The kinds of excuses children give for harmful acts they commit

(B) The age at which children begin to discriminate between intentional and unintentional harm

(D) The circumstances under which children punish harmful acts

(E) The justifications children recognize for mitigating punishment for harmful acts

9.According to the passage, Keasey's findings support which of the following conclusions about six-year-old children?

(A)They have the ability to make autonomous moral judgments.

(B)They regard moral absolutism as a threat to their moral autonomy.

(C)They do not understand the concept of public duty.

(D)They accept moral judgment made by their peers more easily than do older children.

(E)They make arbitrary moral judgments.

The term “remote sensing” refers to the techniques of measurement and interpretation of phenomena from a distance.

“遥感” 这个词涉及远距离测量及解读信息的技术。

Prior to the mid-1960's the interpretation of film images was the primary means for remote sensing of the Earth's geologic features.

1960 年代中期以前，地质学特征的遥感主要是通过对胶片上图像的解读。

With the development of the optomechanical scanner, scientists began to construct digital multispectral images using data beyond the sensitivity range of visible light photography.

随着光学机械扫描仪的发展，科学家开始用超越可见光摄影敏感范围的数据，构建多光谱数码图像。

These images are constructed by mechanically aligning pictorial representations of such phenomena as the reflection of light waves outside the visible spectrum, the refraction of radio waves, and the daily changes in temperature in areas on the Earth's surface.

这些图像的构建，要通过对一些现象进行机械校准，像不可见光的反射，无线电波的折射，以及该区域内地表温度的日常变化。

The advantage of digital over photographic imaging is evident: the resulting numerical data are precisely known, and digital data are not subject to the vagaries of difficult-to-control chemical processing.

数码图像相较于胶片感光成像的优势显而易见：由大量数据产生的结果更精确，而且数据不会受制于各种难以掌控的化学步骤。

8. It can be inferred from the passage that a major disadvantage of photographic imaging in geologic mapping is that such photography

(A) cannot be used at night

(B) cannot focus on the details of a geologic area

(D) is always enhanced by digital reconstruction

(E) cannot reflect changes over extended periods of time

选 C

细节题。

问传统办法的 major disadvantage 其实等于问新技术的 advantage，回到句 5：

细节题是不是可以不读文章直接用关键字回溯文段来节省时间?

我个人觉得不能，因为很多细节题的问法是相对隐蔽的，不读懂文段大意，定位经常可能不准，一个稍微精致的干扰就能让人中招。而这种方法之所以听起来不错，因为它和所有事后诸葛一样。所以，老实点，不要想取巧了。

GRE阅读:每天练习长难句

1. Although some experiments show that，as an object becomes familiar，its internal representation becomes more holistic and the recognition process correspondingly more parallel，the weight of evidence seems to support the serial hypothesis， at least for objects that are not notably simple and familiar. (4+)

虽然某些实验表明，随着一个物体变得熟悉起来，其内心再现图像亦更具整体感，辨认过程相应地更趋于平行，但证据的砝码似乎在支持序列假设(serial hypothesis)，至少是对于那些不甚简单、不甚熟悉的物体来说。

难句类型：复杂修饰、插入语、省略

解释：在Although引导的分句中，谓语shows后面跟着一个长长的宾语从句，从句中先出现一个插入语as an object becomes familiar,之后的内容是由and 连接的两套并列的主谓宾。其实and前后就是两个句子，只不过作者省略了后面的句子中与前面相同的引导词that和谓语become。

句子中有一个生词holistic，其实即使不认识，也能用合理化原则猜出它是后面serial的反义词、parallel的同义词，大约是统一、完整或同时的意思;其实只要能理解到其是与serial相反的意思即可。

意群训练：Although some experiments show that，as an object becomes familiar，its internal representationbecomes more holistic and the recognition process correspondingly more parallel，the weight of evidence seems to support the serial hypothesis, at least for objects that are not notably simple and familiar.

This preference for exogamy，Gutman suggests， may have derived from West African rules governing marriage，which，though they differed from one tribal group to another，all involved some kind of prohibition against unions with close kin. (3+)

难句类型：复杂修饰、插入语

译文：古特曼表示，这种对于外部通婚的偏爱很有可能缘起于西部非洲制约着婚姻的规定，尽管这些规定在一个和另一个部落群体之间不尽相同，但都涉及到某种对近亲联姻(union with close kin)的禁止。

解释：本句有两个插入语，第一个插入语Gutman suggests割裂了主句的主语和谓语。West African rules后跟着两个修饰成分，第一个是分词修饰(governing marriage), 第二个是以which引导的非限定性定语从句，从句中出现了第二个插入语though they differed from one tribal group to another，又割裂了从句引导词与谓语之间的联系。

意群训练：This preference for exogamy，Gutman suggests， may have derived from West African rules governing marriage，which，though they differed from one tribal group to another，all involved some kind of prohibition against unions with close kin.

Partha has withdrawn its troops from Baltia after five years of occupation. Earlier this year the country of Cardcna began shipping mules to Baltia's resistance fighters to facilitate transport of weapons across Baltia's mountains to the battle areas. Cardena's diplomats now claim that without

Cardena's aid to Baltia's resistance fighters, Partha would not have withdrawn.

Which of the following, if true, casts the most serious doubt on the accuracy of the assertion of Cardena's diplomats?

(A) No precise figures are available concerning the number of mules shipped to Baltia.

(B) During the past year, Cardena shipped weapons and food, as well as mules, to resistance fighters in Baltia.

(C) Last year a new government took power in Partha and decided that national interests were not served by the occupation of Baltia.

(D) Two years ago Partha had no plans to reduce its forces in Baltia.

(E) Resistance fighters in Baltia fought for five years against Partha's occupying troops.

答案：(C)

问题: 下面哪一个如果正确的话,最能反对外交家断言的正确性

读题: 在5年的占领后，P从B撤军。今年的早些时候C开始运送骡子给B的抵抗部队，以方便在B国山区的运输。现在C外交官宣称，没有C的帮助，P不会撤军。

分析:题中第一句话就告诉我们一个事实，P从B撤军了，而C外交家断言说:这是因为C的帮助，问题是反对C外交官的宣称，也就是要反对原因。

两种weaken反对方式:

1、直接说到和原因不一样就对。

2、有其它的原因来解释P为什么撤军(这种题型中这种答案占多数)

B、去年, C运送武器,食物和骡子给B国抵抗部队 support，和原因是相同点。

C、去年P国一个新政府上台，认为占领B并没有获利 weaken, 其他原因解释为什么撤军, 占领并不获利,所以撤军

E、抵抗部队和P国军队战斗了5年。不要进一步联想是抵抗部队打跑了P，它只是说战斗而已

对于新GRE逻辑阅读，考生除了采取题海战术，其实更应该做的就是总结。如果能从平日的练习中找到解新GRE逻辑阅读题的思路，那么，要比采取题海战术更好。

How can the hormone adrenaline that does not act directly on the brain have a regulatory effect on brain function? Recently, we tested the possibility that one of the hormone's actions outside the brain might be responsible. Since one consequence of adrenaline release in an animal is an increase in blood glucose levels, we examined the effects of glucose on memory in rats. We found that glucose injected immediately after training enhances memory tested the next day. Additional evidence was provided by negative findings: drugs called adrenergic antagonists, which block peripheral adrenaline receptors, disrupted adrenaline's ability to regulate memory but did not affect memory enhancements produced by glucose that was not stimulated by adrenaline. These results are as they should be if adrenaline affects memory modulation by increasing blood glucose levels. (131 words)

10.The author refers to the results of the experiment using adrenergic antagonists as “negative findings” most likely because the adrenergic antagonists

(A) failed to disrupt adrenaline's effect on memory

(B) did not affect glucose's ability to enhance memory.

(D) only partially affected adrenaline's ability to enhance memory

(E) disrupted both adrenaline's and glucose's effect on memory

Our words are meaningless and cannot be distinguished from their opposites, as can be proved by an example. People think that they know the difference between the meanings of “bald” and “having hair.” Suppose an average person twenty-one years of age has N hairs on his or her head. We say that that person is not bald but has hair. But surely one hair less would make no difference, and a person with N-1 hairs on his or her head would be said to have hair. Suppose we kept on, with one hair less each time. The result would be the same. But what would be the difference between someone who had one hair and someone who had none? We call them both bald. Nowhere can we make a distinction between “bald ” and “having hair.”

Which of the following statements best counters the argument above?

The word “bald” can be translated into other languages.

A word can have more than one meaning.

A word such as “cat” can be applied to several animals that differ in some respects.

Words can lack precision without being meaningless.

People cannot think clearly without using words.

答案：(D)

That sales can be increased by the presence of sunlight within a store has been shown by the experience of the only Savefast department store with a large skylight. The skylight allows sunlight into half of the store, reducing the need for artificial light. The rest of the store uses only artificial light. Since the store opened two years ago, the departments on the sunlit side have had substantially higher sales than the other departments.

Which of the following, if true, most strengthens the argument?

(A) On particularly cloudy days, more artificial light is used to illuminate the part of the store under the skylight.

(B) When the store is open at night, the departments in the part of the store under the skylight have sales that are no higher than those of other departments.

(D) Besides the skylight, there are several significant architectural differences between the two parts of the store.

(E) The departments in the part of the store under the skylight are the departments that generally have the highest sales in other stores in the Savefast chain.

gre阅读考试中心句如何找到?

为何要找gre阅读文章中心句?

之所以强调中心句，主要还是为了应对GRE阅读考试的出题思路。大家需要明确的一点是，想要做好GRE长篇阅读，考生其实并不需要把整篇文章都读懂吃透才能解题。许多类似主旨题态度题的阅读题目，考生只要能够结合文章中心句大致理解整体意思就能毫无困难的解题。gre阅读方法,gre考试培训而文章中许多细节案例，其实往往都是毫无用处的过量信息，纯粹是为了消耗大家时间而故意挖下的陷阱。因此，面对长篇阅读，考生首先要做的不是读完全文，而是找到中心句加快理解速度。

根据gre阅读考试文章套路结构找中心句

那么，如何才能快速找到中心句呢?这里小编建议大家结合GRE阅读文章本身的类型来寻找，一般来说，GRE阅读文章可以大致分为三种类型，每种类型的中心句位置各有不同，考生gre阅读考试解题需要根据文章类型来寻找中心句，具体如下：

A. 现象解释型文章

B. 新老观点型文章

中心句在新观点处(注意旧观点的取非)。

C. 问题解决方案型文章

中心句位于相应的解决方案处。

从语言现象中发现中心句提示信息

除了根据文章套路来找中心句外，gre阅读方法,gre考试培训大家有时候还可以根据文章本身的一些语言现象来找到暗示中心句所在的提示信息。

A. 一段叙述后有转折连词

but, yet, however, actually, in fact, indeed, virtually, practically等，中心句位于转折之后作者态度处。

B. 设问以及回答

作者的自问自答，中心句位于回答处。

C. 大段举例

举例前的理论说明或者之后的归纳易成为中心句。

GRE阅读练习题：地球冷暖周期通过石头含铁量推定

Recent studies of sediment in the North Atlantic’s deepwaters reveal possible cyclical patterns in the history of Earth’s climate. Therock fragments in these sediments are too large to have been transported thereby ocean currents; they must have reached their present locations by travelingin large icebergs that floated long distances from their point of origin beforemelting.

Geol.ist Gerard Bond noticed that some of the sedimentgrains were stained with ironoxide, evidence that they originated in localeswhere glaciers had overrun outcrops of red sandstone. Bond’s detailed analysisof deep-water sediment cores showed changes in the mix of sediment sources overtime: the proportion of these red-stained grains fluctuated back and forth fromlows of 5 percent to highs of about 17 percent, and these fluctuations occurredin a nearly regular 1,500-year cycle.

Bond hypothesized that the alternating cycles might beevidence of changes in ocean-water circulation and therefore in Earth’sclimate. He knew that the sources of the red-stained grains were generallycloser to the North Pole than were the places yielding a high proportion of“clean” grains. At certain times, apparently, more icebergs from the ArcticOcean in the far north were traveling south well into the North Atlantic beforemelting and shedding their sediment. Ocean waters are constantly moving, andwater temperature is both a cause and an effect of this movement. As watercools, it becomes denser and sinks to the ocean’s bottom. During some periods,the bottom layer of the world’s oceans comes from cold, dense water sinking inthe far North Atlantic. This causes the warm surface waters of the Gulf Streamto be pulled northward. Bond realized that during such periods, the influx ofthese warm surface waters into northern regions could cause a large proportionof the icebergs that bear red grains to melt before traveling very far into theNorth Atlantic. But sometimes the ocean’s dynamic changes, and waters from theGulf Stream do not travel northward in this way. During these periods, surfacewaters in the North Atlantic would generally be colder, permitting icebergsbearing red-stained grains to travel farther south in the North Atlantic beforemelting and depositing their sediment.

The onset of the so-called Little Ice Age (1300-1860),which followed the Medieval Warm Period of the eighth through tenth centuries,may represent the most recent time that the ocean’sdynamic changed in this way. If ongoing climate-history studies support Bond’shypothesis of 1,500-year cycles, scientists may establish a major natural rhythmin Earth’s temperatures that could then be extrapolated into the future.Because the midpoint of the Medieval Warm Period was about A.D. 850, anextension of Bond’s cycles would place the midpoint of the next warm intervalin the twenty-fourth century.

21.1. According to the passage, which of the following istrue of the rock fragments contained in the sediments studied by Bond?

A. The majority of them are composed of red sandstone.

B. They must have reached their present location over 1,500 years ago.

C. They were carried byicebergs to their present location.

D. Most of them were carried to their present location during a warm period inEarth’s climatic history.

E. They are unlikely to have been carried to their present location during theLittle Ice Age.

21.2. In the final paragraph of the passage (lines 27-33),the author is concerned primarily with

A. answering a question about Earth’s climatic history

B. pointing out a potential flaw in Bond’s hypothesis

C. suggesting a new focus for the study of ocean sediments

D. tracing the general history of Earth’s climate

E. discussing possibleimplications of Bond’s hypothesis

21.3. According to the passage, Bond hypothesized that whichof the following circumstances would allow red-stained sediment grains to reachmore southerly latitudes?

A. Warm waters being pulled northward from the GulfStream

B. Climatic conditions causing icebergs to melt relatively quickly

C. Icebergs containing a higher proportion of iron oxide than usual

D. The formation of more icebergs than usual in the far north

E. The presence of coldsurface waters in the North Atlantic

21.4. It can be inferred from the passage that in sedimentcores from the North Atlantic’s deep waters, the portions that correspond tothe Little Ice Age

A.. differ very little in composition from theportions that correspond to the Medieval Warm Period

B. fluctuate significantly in composition between the portions corresponding tothe 1300s and the portions corresponding to the 1700s

C. would be likely tocontain a proportion of red-stained grains closer to 17 percent than to 5percent

D. show a much higher proportion of red-stained grains in cores extracted fromthe far north of the North Atlantic than in cores extracted from further south

E. were formed in part as

GRE阅读练习：Sea Cow

The dis appearance of Steller's sea cow from the Bering and Copper is lands by 1768 has long been blamed on intensive hunting. But its dis appearance took only 28 years from the time Steller first described the species, a remarkably short time for hunting alone to depopulate the is lands, especially given the large populations initially reported. However, by 1750, huntershad also targeted nearby sea otter populations . Fewer otters would have allowed s ea urchin populations on which the otterspreyed to expand and the urchins ' grazing pressure on kelp forests to increase. Sea cows were totally dependent on kelp for food, and within a decade of the onset of otter hunting Steller noted that the is lands' sea cows appeared malnourished.

1. Which of the following can be inferred from the pas s age about kelp forests in the Bering and Copper is lands between 1750 and 1768?

A. They were reduced significantly.

B. They disappeared entirely from the region.

C. They were the primary food source for sea otters .

D. They were harvested in record numbers by humans

E. They increased pressure on sea urchin populations.

攻克GRE阅读理解长难句技巧

Part 1

信号词/符识别

长难句中信息量较大，结构较复杂，因而连词、副词、固定搭配，甚至标点符号也较多。理解句子关联需要同时把握好各种信号词和标点符号。

1) 信号词

并列关系：常见连接词有并列连词and，but，or，while，for，so，neither，nor等，还有连接副词，如still，yet，however，consequently，there-fore，then等。还有一些相当于连接词的词组，如：on the contrary，not only…but also，on(the)one hand…on the other hand等。

主从关系：英语从句主要分为名词性从句，定语从句和状语从句。引导名词性从句的关联词主要有that，whether，who，whom，whose，which，what，where，when，how，why，whoever，whomever，whichever，whatever等。引导定语从句的关系代词主要有who, whom, whose, which, that;关系副词有when，where，why等。引导状语从句的连词主要有when，before， until，where，because，so that，if，unless，as if，though等。

2)标点符号

逗号：词的并列，单句的并列，分隔状语及插入语

“I'd like to,” he said, “but I can’t.”

冒号：引出下文，列举，解释，说明

His favorite foods are as follows: apple pie, fruit juice, and chocolate.

破折号：分隔同位语或其他附加成分，分隔插入语，强调，概括

He is the exact person -- the person that I expected.

Part 2

句子结构

由于长难句会由多层次的并列句和主从句构成，且会出现语序的变化，信息的省略，以及打断句子或者补充说明的现象，因此理解修饰关系，并理解倒装、省略、插入语、同位语等语法知识有利于加强我们对句子的剖析。下面，我们来看几个例子：

1)That sex ratio will be favored which maximizes the number of descendants an individual will have and hence the number of gene copies transmitted.

解析：此句信号语为“which”和“and”。“which”修饰主语“that sex ratio”，“will be favored”为谓语，一般定语从句与先行词紧挨，而本句which从句后置，属于倒装的一种。“and”连接两个“the number of”结构，亦可以理解成“and hence”后面省略了动词“maximizes”。 “transmitted”作为非谓语动词修饰 “copies”。

2)Gutman argues convincingly that the stability of the Black family encouraged the transmission of--and so was crucial in sustaining--the Black heritage of folklore, music, and religious expression from one generation to another, a heritage that slaves were continually fashioning out of their African and American experiences.

解析：此句信号语为逗号，破折号和“that”和“and”。第一个“that”引起宾语从句。破折号中间成分为插入语，两个逗号和“and”表明“folklore”, “music”和“religious expression”三组名的并列。第三个逗号则提示了“a heritage”结构为“the Black heritage”的同位语。最后的“that”为“heritage”的定语从句。

3)Fundamentally, however, the conditions under which women work have changed little since before the Industrial Revolution: the segregation of occupations by gender, lower pay for women as a group, jobs that require relatively low levels of skill and offer women little opportunity for advancement all persist, while women’s household labor remains demanding.

解析：此句信号语为逗号、冒号、“while”、“which”、“that”和“and”。逗号同样起到划分意群的作用。冒号的作用为解释说明，引起下文的并列结构。“while”分句与前半句是并列关系。“which”和“that”引导意群内部的定语从句。“and”则连接从句内部的并列谓语。

Part 3

逻辑

当你以为理解清楚句子结构就万事大吉的时候，我奉劝大家一定要淡定，因为最重要的一步也是最后一步还等待我们挖掘，那就是理解句子逻辑。我们知道GRE是一项逻辑考试，需要在读句子的时候就明确句子的逻辑要点。只有这样，我们才能更加快速的理清考点。你以为理解了句子内容就足够了吗?其实考题不以内容为主，有木有?所以，逻辑要点才需要我们加强分析。

以上述三个句子为例：

第一句强调“favor”这个正态度，且“maximizes the number of descendants”这个信息是优势基因复制的根本原因。

第二句“Gutman argues”表明某人的观点，“the stability of the Black family”与后文提到的文化得以传承是因果关系。

第三句女性工作环境变化小的原因是中间的一组列举，所以因果关系和列举就是考点。

如何快速理解GRE长难句?

精简句子结构

GRE阅读理解的考查重点不在词汇上，而是句子结构和句与句、段与段之间的逻辑关系。其中复杂修饰成分是干扰考生选择答案的很大障碍，非常浪费时间，容易造成理解上的偏差，打断阅读思路。在阅读过程中，如果能将这些复杂修饰成分进行调整、删减、压缩，使之变得简单，阅读速度和准确率都会有所提高的。

抓住句子主干

从广义上来说，从句、分词、不定式、插入语、介词短语等都可以看作GRE阅读的复杂修饰成分，带有这些复杂修饰成分的句子都比较长，读起来拗口。在遇到这类句子时，建议大家不必详细梳理，先抓住句子主干。有些成分对考生做题没有任何影响，倘若浪费太多时间去分析句子的某一处，无异于浪费了宝贵的考试时间。这个步骤，其实就是一个去粗取精，去伪存真的过程。

以上就是快速理解GRE阅读长难句的方法技巧介绍，需要明确的一点是，GRE阅读的长难句是必然会在考试中出现的。所以掌握好解决长难句的方法必不可少，上文的内容可以给大家带来一些提示，祝各位考生都能在GRE考试中取得满意的成绩。

TIPS：GRE阅读备考也需要认真背单词

虽然GRE阅读的重点考察目标并不是单词，但词汇量不足还是会影响全文理解和对细节题的解答。所以，GRE阅读考试需要认真背单词。而且，考生考G也是为了出国，从这个根本目标出发，单词的积累也是重要的。或许有人会问，看哪本GRE词汇书?实际上，市面上常见的任何一本单词书拿来应对考试都不会有什么问题。关键在于是否能持之以恒地把一本书啃透。有人或许会问，专业词汇到底看不看，看的话当然最好，不看实际上也不影响理解文章并解答题目。如果考生时间比较紧张的话，还是建议不要背了，毕竟背单词是一个很杀时间的事情。

篇6：GRE阅读主题句写法特点

GRE阅读主题句写法特点分析找对主题句看清文章套路

GRE阅读主题句特点形式介绍

美国人的思维和我们并不一样，和国内考生写文章也不一样，美国人的阅读文章中从来都不出现“I think that，in my opinion，as far as I am considered”此类语言做主题句。通常来说主题句有以下两种形式：

1. 判断句(含情态动词，系动词，正负褒贬词的句子)。

2. 概括文章将来结构。

比如下面的一个句子：Your minds changed my attitude. 这句话中并没有加入情态动词和系动词，因此这句话自然不是判断句，也就不是主题句。但只要在这句话中加入一个正负褒贬词，即一个词表明作者的态度或观点的词即是判断句了。比如，Your minds successfully changed my attitude即是判断句了。

学会判断主题句有哪些好处?

如果考生在新GRE阅读题中掌握好了主题句判断方法，很多文章便可以很快把握文章的结构框架，帮助后面文章的理解。

比如一篇文章的开头是：Mycorrhizal fungi infect more plants than do any other fungi and are necessary for many plants to thrive， but they have escaped widespread investigation until recently for two reasons. First， the symbiotic association is so well-balanced that the roots of host plants show no damage even when densely infected. Second， the fungi cannot as yet be cultivated in the absence of a living root.

GRE阅读：考试时陌生词汇怎么应对

基于这一点，我们大家大可不必因为遇到了几个我们完全没见过的奇形怪状的GRE词汇而感到头痛和挣扎。因为它们不足以对我们理解文章产生影响。

gre文章是论证性文字，不是说明性文字，也不是叙述性文字。这种以论证为特点的文字，及于gre阅读文章的各个层面：“篇章—段落—句子—单词”。篇章由多个论点组成，论点由作为论据的句子构成，句子本身的典型构成是前后句由表示论证关系的词汇连接，而体现论证的意义的单词最重要。

因此，要真懂得文章，就必须把所有那些表现论证的字、词、句抓出。但是面对浩如烟海的GRE词汇，我们如何才能做到准确的去把握词义，把握文章的主要内容呢?

但同时，我们在阅读文章的过程中也常常会碰到这样的一种单词，那就是专有名词，尤其是涉及全文主题的专有名词，难道我们就必须一一认识它?答案显然是否定的。什么叫做认识专有名词?从英到汉的翻译叫做认识?还是知道专有名词的特征叫做认识?读者请想想看，我们在阅读理解中有没有遇到过这样的问题提法：

What is sedge root- 我想没有，因为这种问法是在问专有名词的翻译。我们遇到的更多是这样的一些问法：According to the passage, which of the following statements about sedge root is true- What can be inferred from the passage about sedge root- 这些问题的提法却是在问专有名词的文中阐述特征。我们再从文章本身对这个问题做出进一步的分析。

GRE阅读：利用文章结构来解题

1. 结论-解释型(也叫论点-解释型)

2. 新老观点对比型

3. 现象解释型(包含问题-解决方案型)

首先是“结论-解释型”文章。这类文章在开始有一个判断句，一般是文章的结论，也是文章的主题。这个判断句的谓语部分通常包含系动词(is, remain, prove, turn out, appear等)或情态动词(can, may, should, must等)，而且含有表示态度的词汇(如形容词等)。例如，

Because of its accuracy in outlining the Earth's subsurface, the seismic-reflection method remains the most important tool in the search for petroleum reserves. In field practice, a subsurface is mapped by arranging a series of wave-train sources, such as small dynamite explosions, in a grid pattern…

文章首句指出：“由于‘地震反射法’(sr)在勾划地球的地下层面这方面的准确性，该方法一直是探寻石油储备的最重要的工具。”这是一个判断句，为结论。其中remains为系动词，而most important为态度词，表示作者对“地震反射法”持非常正面的评价。

后文应解释“地震反射法”的具体过程。第二句话对解释进行总的说明：“在实地作业中，通过将一系列波列源，诸如小规模炸药爆炸，排列成一个网格模式，从而将地下层面标绘出来。”接下来是“地震反射法”的详细过程。

GRE阅读文章的第二种常见结构是“新老观点对比型”。这类文章在开始提出老观点，然后提出新观点并进行论述。通常新观点是文章的主题。老观点出现的标志词有：

1. 传统观点： has been, traditionally, until recently等

2. 大众观点：frequently, widely, many等

新观点出现的标志词有：however, recently, now等。

例如：

Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used。

However, a number of features that are characteristic of wind-pollinated plants reduce pollen waste…

文章首句指出：“传统上，风媒授粉过程一直被视为是一个以随机事件为标志的繁殖过程，其中风的不确定性通过产生大量花粉而得以补偿，因此，新种子的最终繁殖得以保证，而此举的代价是所需产生的花粉要远远超过实际的使用量。”由第一个词traditionally可知文章首句为老观点(由于风的不确定性，风媒植物要产生大量花粉补偿)，那么本文的结构是“新老观点对比型”。

第二段首句出现了GRE阅读中的标志性转折词however，说明这句话就是新观点：“但是，风媒植物所独有的一系列特征可减少花粉浪费。”这说明风媒植物除了可以产生大量花粉加以补偿的消极策略之外，还可以通过一些积极机制减少花粉损失，不一定需要产生大量花粉。

GRE阅读文章的第三种常见结构是“现象解释型”。文章开始提出一个现象，然后解释现象。解释是主题。有多个解释时，作者一般对前面的解释持负面评价，对最后的解释持正面评价。提出现象时的标志词有：phenomenon, fact; problem, difficulty, puzzle, question等。例如，

What causes a helix in nature to appear with either a dextral (“right-handed,”or clockwise) twist or a sinistral (“left-handed,” or counterclockwise') twist is one of the most intriguing puzzles in the science of form…What mechanisms, control handedness and keep left-handedness rare?

It would seem unlikely that evolution should discriminate against sinistral snails if sinistral and dextral snails are exact mirror images, for any disadvantage that a sinistral twist in itself could confer on its possessor is almost inconceivable. But left- and right-handed snails are not actually true mirror images of one another…

But this evolutionary mechanism combining dissymmetry, anatomy, and chance does not provide an adequate explanation of why right-handedness should have become predominant…

Here, the evolutionary theory must defer to a theory based on an explicit developmental mechanism that can favor either right- or left-handedness…Thus, the path to a solution to the puzzle of handedness in all snails appears to be as twisted as the helix itself.

是什么样的原因致使自然界中的螺旋体呈现出右旋(“右向旋转的”，或顺时针的)或左旋(“左向旋转的，”或反时针的)?这是形态科学中一个最引人入胜的不解之谜....。。究竟是一些什么样的机制控制着旋转方向，并使左旋的比例为数稀少呢?

假如左旋和右旋蜗牛呈完全一致的镜像对称的话，那么进化对左旋蜗牛不利，这近乎不太可能。几乎无法想象左旋本身会给左旋者带来任何不利之处。然而，左旋与右旋蜗牛彼此间实际上并不呈真正的镜像对称……

但是，这种结合不对称、解剖学和偶然性的进化论机制并未提供一种充分的解释，以说明蜗牛的右旋何以会成为主要的旋向……

于是，进化论必须让位于支持右旋或左旋的明确的发育机制为基础的理论……因此，解决所有蜗牛身上旋向之谜的道路似乎与这一螺旋体本身一样曲折复杂。

上文在第一段最后提出一个问题：“究竟是一些什么样的机制控制着旋转方向，并使左旋的比例为数稀少呢??”这个问题就是一个现象：螺旋体中左旋的比例少。有问题就有解答，有现象就有解释。第二段从进化论的角度解释这一现象。但是，GRE阅读文章中一般对进化论的解释持负面评价，所以需要寻找新的解释。第三段否定了进化论的解释。在末段，作者以发育机制(developmental mechanism)解释“为何左旋少、右旋多”。

把握了文章的三种主体结构以后，做文章后的许多题时易如反掌。以上述的“结论——解释型”文章为例，如果熟悉文章的主体结构，下面两道题就很容易找到正确答案。

1. The passage is primarily concerned with

(A) describing an important technique

(B) discussing a new method

(D) announcing a significant discovery

(E) promoting a novel application

正确答案对应文章首句的主题句。因此(A)为正确答案。

2. Which of the following best describes the organization of the passage?

(A) A method is criticized, and an alternative is suggested。

(B) An illustration is examined, and some errors are exposed。

(D) A series of examples is presented, and a conclusion is drawn。

(E) A hypothesis is advanced, and supporting evidence is supplied。

本文的结构是“结论—解释型”，因此(C)为正确答案。

篇7：GRE阅读找对中心句合理提速

GRE阅读提速从找准中心句开始

之所以强调中心句，主要还是为了应对GRE阅读考试的出题思路。大家需要明确的一点是，想要做好GRE长篇阅读，考生其实并不需要把整篇文章都读懂吃透才能解题。许多类似主旨题态度题的阅读题目，考生只要能够结合文章中心句大致理解整体意思就能毫无困难的解题。而文章中许多细节案例，其实往往都是毫无用处的过量信息，纯粹是为了消耗大家时间而故意挖下的陷阱。因此，面对长篇阅读，考生首先要做的不是读完全文，而是找到中心句加快理解速度。

篇8：GRE阅读找对中心句合理提速

那么，如何才能快速找到中心句呢?这里小编建议大家结合GRE阅读文章本身的类型来寻找，一般来说，GRE阅读文章可以大致分为三种类型，每种类型的中心句位置各有不同，考生需要根据文章类型来寻找中心句，具体如下：

A. 现象解释型文章

文章开始给出现象，之后必定有解释，中心句在解释给出处。若解释不止一个，中心句则为给予正评价的那个。

B. 新老观点型文章

中心句在新观点处(注意旧观点的取非)。

C. 问题解决方案型文章

中心句位于相应的解决方案处。

结合文章句型关键词寻找中心句

除了根据文章套路来找中心句外，大家有时候还可以根据文章本身的一些语言现象来找到暗示中心句所在的提示信息。

A. 一段叙述后有转折连词

but, yet, however, actually, in fact, indeed, virtually, practically等，中心句位于转折之后作者态度处。

B. 设问以及回答

作者的自问自答，中心句位于回答处。

C. 大段举例

举例前的理论说明或者之后的归纳易成为中心句。

总而言之，考生如果想在较短时间内更有效率地做好GRE阅读，特别是一些长篇阅读，那么找中心句的技巧就是必不可少的了。而上文中的内容，无疑将帮助大家更好地掌握这种技巧。

如何有效应对GRE阅读突然卡壳

建议1：原来英文基础不错，但是GRE阅读复习有他独特的逻辑结构和出题思路，所以有了好的英文基础，还必须去专门总结、反复练习达到对这种考试结构的敏感和熟练。

建议2：通过你的阅读训练难以克服GRE阅读，恰恰说明了我讲的第一点，GRE有他的特殊性，难句是克服阅读基本障碍的，之后就应该把注意力转移到针对GMAT的集中突破总结上，读外文期刊是细水常流练习阅读的方式，有限的复习时间里建议放弃，把时间转移到OG的集中突破总结上，当把所有OG(有时间+补充材料的阅读文章)总结4-5 遍以上，你自会有顿悟的。

建议3：别看简单，但是这种有针对性的总结对GRE阅读的领悟是很有帮助的，在几遍总结中，请注意加强原文逻辑结构的阅读;练习题干-选项-原文的对应关系的敏感度，即如何找到ETS给你藏好的答案，如何迅速排除错误答案。请一定读一遍我的阅读示范，会明白我讲的如何取舍的读文章，如何找答案的意思。 (参考Mumu阅读示范)

建议4: GRE阅读复习是逻辑和语法两项的基础，提高阅读也会给其他两项提速，如果其他两项做题时也有对整体逻辑框架把握不准做题慢的问题，那么不妨把更多时间用来阅读集中突破，其他两项为辅。

建议5：参考其他人的经验

良好的GRE阅读理解习惯培养方法

1.解剖文章的第1段

新GRE考试中阅读部分需要考生积极主动地解读文章的第1段，阅读时尽量记住作者提出的问题(现象或观点)，和一些关于文章内容的概念和词汇，如这篇文章讲的是生物化学，日本企业文化还是黑人运动。文章的论题是什么，作者想说什么-

2.在脑子里面形成一个作者思路图

在脑子里或者在草稿纸上画一个文章的结构思路题。各个段落的目的是什么，主题又是什么-再次提醒，考察的是你的答题能力而非阅读能力。你不必完全掌握整篇文章，了解文章中的每一个细节(其实，你也没有那么多时间)。相反，你应该只读文章段落的第1句，而快速浏览其余部分。当你“读”完这篇文章时，你就能对文章的结构思路有总体的把握。

3.通览文章时，留意语气词和过渡词

在快速阅读文章时，特别留意段落开头或者结尾可能出现的语气词和过渡词。这样做有助于你对作者思路的把握，从而快速掌握文章大意。

4.停下来，总结一下文章大意

在回答问题前，花几秒钟总结一下文章的思路和主题。

5.开始答题

根据你对文章的整体思路来答题。将问题(或选项)定位到文章中具体的某个段落甚至具体的句子。这里，你可以比第3个步骤更仔细。

GRE阅读练习

Many critics of Emily Bronte’s novel Wuthering Heights see its second part as a counterpoint (a complementing or contrasting item: OPPOSITE) that comments on, if it does not reverse, the first part, where a “romantic” reading receives more confirmation. Seeing the two parts as a whole is encouraged by the novel’s sophisticated structure, revealed in its complex use of narrators and time shifts. Granted that the presence of these elements need not argue an authorial awareness of novelistic construction comparable to that of Henry James, their presence does encourage attempts to unify the novel’s heterogeneous parts. However, any interpretation that seeks to unify all of the novel’s diverse elements is bound to be somewhat unconvincing. This is not because such an interpretation necessarily stiffens into a thesis (although rigidity in any interpretation of this or of any novel is always a danger), but because Wuthering Heights has recalcitrant elements of undeniable power that, ultimately, resist inclusion in an all-encompassing interpretation. In this respect, Wuthering Heights shares a feature of Hamlet.

17. According to the passage, which of the following is a true statement about the first and second parts of Wuthering Heights?

(A) The second part has received more attention from critics.

(B) The second part has little relation to the first part.

(D) The second part provides less substantiation for a “romantic” reading.

(E) The second part is better because it is more realistic.

18. Which of the following inferences about Henry James’s awareness of novelistic construction is best supported by the passage?

(A) James, more than any other novelist, was aware of the difficulties of novelistic construction.

(B) James was very aware of the details of novelistic construction.

(D) James’s awareness of novelistic construction has led most commentators to see unity in his individual novels.

(E) James’s awareness of novelistic construction precluded him from violating the unity of his novels.

19. The author of the passage would be most likely to agree that an interpretation of a novel should

(A) not try to unite heterogeneous elements in the novel

(B) not be inflexible in its treatment of the elements in the novel

(D) concentrate on those recalcitrant elements of the novel that are outside the novel’s main structure

(E) primarily consider those elements of novelistic construction of which the author of the novel was aware

20. The author of the passage suggests which of the following about Hamlet?

I. Hamlet has usually attracted critical interpretations that tend to stiffen into theses.

II. Hamlet has elements that are not amenable to an all-encompassing critical interpretation.

III. Hamlet is less open to an all-encompassing critical interpretation than is Wuthering Heights.

IV. Hamlet has not received a critical interpretation that has been widely accepted by readers.

(A) I only

(B) II only

(D) III and IV only

(E) I, II, and III only

The determination of the sources of copper ore used in the manufacture of copper and bronze artifacts of Bronze Age (Bronze Age: n. 铜器时代) civilizations would add greatly to our knowledge of cultural contacts and trade in that era. Researchers have analyzed artifacts and ores for their concentrations of elements, but for a variety of reasons, these studies have generally failed to provide evidence of the sources of the copper used in the objects. Elemental composition can vary within the same copper-ore lode, usually because of varying admixtures of other elements, especially iron, lead, zinc, and arsenic. And high concentrations of cobalt or zinc, noticed in some artifacts, appear in a variety of copper-ore sources. Moreover, the processing of ores introduced poorly controlled changes in the concentrations of minor and trace elements in the resulting metal. Some elements evaporate during smelting and roasting; different temperatures and processes produce different degrees of loss. Finally, flux, which is sometimes added during smelting to remove waste material from the ore, could add quantities of elements to the final product.

An elemental property that is unchanged through these chemical processes is the isotopic composition of each metallic element in the ore. Isotopic composition, the percentages of the different isotopes of an element in a given sample of the element, is therefore particularly suitable as an indicator of the sources of the ore. Of course, for this purpose it is necessary to find an element whose isotopic composition is more or less constant throughout a given ore body, but varies from one copper ore body to another or, at least, from one geographic region to another.

The ideal choice, when isotopic composition is used to investigate the source of copper ore, would seem to be copper itself. It has been shown that small but measurable variations occur naturally in the isotopic composition of copper. However, the variations are large enough only in rare ores; between samples of the common ore minerals of copper, isotopic variations greater than the measurement error have not been found. An alternative choice is lead, which occurs in most copper and bronze artifacts of the Bronze Age in amounts consistent with the lead being derived from the copper ores and possibly from the fluxes. The isotopic composition of lead often varies from one source of common copper ore to another, with variations exceeding the measurement error; and preliminary studies indicate virtually uniform isotopic composition of the lead from a single copper-ore source. While some of the lead found in an artifact may have been introduced from flux or when other metals were added to the copper ore, lead so added in Bronze Age processing would usually have the same isotopic composition as the lead in the copper ore. Lead isotope studies may thus prove useful for interpreting the archaeological record of the Bronze Age.

21. The primary purpose of the passage is to

(A) discuss the techniques of analyzing lead isotope composition

(B) propose a way to determine the origin of the copper in certain artifacts

(D) describe the deficiencies of a currently used method of chemical analysis of certain metals

(E) offer an interpretation of the archaeological record of the Bronze Age

22. The author first mentions the addition of flux during smelting (lines 18-21) in order to

(A) give a reason for the failure of elemental composition studies to determine ore sources

(B) illustrate differences between various Bronze Age civilizations

(D) illustrate the uniformity of lead isotope composition

(E) explain the success of copper isotope composition analysis

23. The author suggests which of the following about a Bronze Age artifact containing high concentrations of cobalt or zinc?

(A) It could not be reliably tested for its elemental composition.

(B) It could not be reliably tested for its copper isotope composition.

(D) It could have been manufactured from ore from any one of a variety of sources.

(E) It could have been produced by the addition of other metals during the processing of the copper ore.

24. According to the passage, possible sources of the lead found in a copper or bronze artifact include which of the following?

I. The copper ore used to manufacture the artifact

II. Flux added during processing of the copper ore

III. Other metal added during processing of the copper ore

(A) I only

(B) II only

(D) II and III only

(E) I, II, and III

25. The author rejects copper as the “ideal choice” mentioned in line 33 because

(A) the concentration of copper in Bronze Age artifacts varies

(B) elements other than copper may be introduced during smelting

(D) among common copper ores, differences in copper isotope composition are too small

(E) within a single source of copper ore, copper isotope composition can vary substantially

26. The author makes which of the following statements about lead isotope composition?

(A) It often varies from one copper-ore source to another.

(B) It sometimes varies over short distances in a single copper-ore source.

(D) It frequently changes during smelting and roasting.

(E) It may change when artifacts are buried for thousands of years.

27. It can be inferred from the passage that the use of flux in processing copper ore can alter the lead isotope composition of the resulting metal EXCEPT when

(A) there is a smaller concentration of lead in the flux than in the copper ore

(B) the concentration of lead in the flux is equivalent to that of the lead in the ore

(D) any lead in the flux has the same isotopic composition as the lead in the ore

(E) other metals are added during processing

GRE阅读练习每日一篇

The stratospheric ozone layer is not a completely uniform stratum, nor does it occur at the same altitude around the globe. It lies closest to the Earth over the poles and rises to maximum altitude over the equator. In the stratosphere, ozone is continuously being made and destroyed by natural processes. During the day the Sun breaks down some of the oxygen molecules to single oxygen atoms, and these reacting with the oxygen molecules that have not been dissociated, form ozone. However, the sunlight also breaks down ozone by converting some of it back to normal oxygen. In addition naturally occurring nitrogen oxides enter into the cycle and speed the breakdown reactions. The amount of ozone present at any one time is the balance between the processes that create it and those that destroy it.

Since the splitting of the oxygen molecules depends directly upon the intensity of solar radiation, the greatest rate of ozone production occurs over the tropics. However ozone is also destroyed most rapidly there, and wind circulation patterns carry the ozone-enriched upper layers of the atmosphere away from the equator. It turns out that the largest total ozone amounts are found at high latitudes. On a typical day the amount of ozone over Minnesota, for example, is 30 percent greater than the amount over Texas, 900 miles farther south. The density and altitude of the ozone layer also change with the seasons, the weather, and the amount of solar activity. Nevertheless, at any one place above the Earth’s surface, the long-term averages maintained by natural processes are believed to be reasonably constant.

The amount of ozone near the Earth is only a small percent of the amount in the stratosphere, and exchange of molecules between the ozone layer and the air at ground level is thought to be relatively small. Furthermore, the ozone molecule is so unstable that only a tiny fraction of ground-level ozone could survive the long trip to the stratosphere, so the ozone layer will not be replenished to any significant degree by the increasing concentrations of ozone that have been detected in recent years near the earth’s surface. The long-term averages of ozone both near ground level (ground level: n.[地质]地水准平面) and in the stratosphere are regulated by continuous processes that are constantly destroying and creating it in each of these places. This is why scientists are so concerned about human beings injection into the stratosphere of chemicals like nitrogen oxides, which are catalysts that facilitate the breakdown of ozone. If the ozone layer is depleted significantly, more ultraviolet radiation would penetrate to the Earth’s surface and damage many living organisms.

17. The passage suggests that factors contributing to the variation in the amount of ozone above different areas of the Earth’s surface include which of the following?

I. Some of the ozone found at higher latitudes was produced elsewhere.

II. There is usually a smaller amount of naturally occurring nitrogen oxide over high latitudes.

III. The rate of ozone production over the poles is less than that over the tropics.

(A) II only

(B) III only

(D) I and III only

(E) I, II, and III

18. Which of the following best states the central idea of the passage?

(A) Naturally occurring nitrogen oxides, as well as those introduced by humans, threaten to deplete the layer of ozone in the stratosphere.

(B) A delicate but reasonably constant balance exists between the natural processes that produce and those that destroy ozone in the stratosphere.

(C) There is little hope that the increased concentrations of ground-level ozone observed in recent years can offset any future depletion of stratospheric ozone.

(D) Meteorologically induced changes in the concentration of ozone in the stratosphere tend to cancel themselves out over a period of time.

(E) Solar radiation not only produces and destroys zone but also poses a hazard to human life.

19. The processes that determine the amount of ozone in a given portion of the stratosphere most resemble which of the following?

(A) Automobile emissions and seasonal fog that create a layer of smog over a city

(B) Planting and harvesting activities that produce a crop whose size is always about the same

(D) Assets and liabilities that determine the net worth of a corporation

(E) High grades and low grades made by a student whose average remains about the same from term to term

20. According to the passage, which of the following has the LEAST effect on the amount of ozone at a given location in the upper atmosphere?

(A) Latitude

(B) Weather

(D) Ground-level ozone

(E) Solar activity

21. The author provides information that answers which of the following questions?

I. What is the average thickness of the stratospheric ozone layer?

II. Why does increased exposure to ultraviolet radiation damage many living organisms?

III. What is the role of oxygen in the production of stratospheric zone?

(A) I only

(B) II only

(D) I and II

(E) II and III

22. In explaining what determines the amount of ozone in the stratosphere, the author describes natural processes that form

(A) an interactive relationship

(B) a reductive system

(D) a set of randomly occurring phenomena

(E) a set of sporadically recurring events

Feelings of hopelessness among medieval workers trapped in the poverty cycle gradually lessened as it became possible for women’s labor to supplement a family’s money income by more than pennies. By 1300, women spinners could be found working on their own (on one's own: adv.独自地, 独立地, 主动地) for wealthy sponsors, even after the introduction in Italy and France of prohibition against advancing money for supplies to women spinners. Historians have usually interpreted this prohibition simply as evidence of women’s economic subjection, since it obliged them to turn to usurers; however, it was also almost certainly a response to a trend toward differential reward for women’s higher skill. Yarn can be spun irregularly and lumpily, but perfectly smooth yarn is worth more. Working for merchant entrepreneurs on time rates, women had been paid hardly more than children; working as entrepreneurs themselves and producing good work by the piece, they could break into (to make entry or entrance into “broke into the house” “break into show business”) the rational system of differential rewards.

23. The primary purpose of the passage is to

(A) propose and defend a theory about the consequences of a certain historical event

(B) present historical facts and offer a broader interpretation of those facts than has been offered in the past

(D) demonstrate the superiority of using an economic approach to historical analysis

(E) call attention to the influence of the textile industry on society during a particular historical period

24. It can be inferred from the passage that the author views the system of paying all workers equally on time rates as

(A) unfair and not rational

(B) undesirable but unavoidable

(D) advantageous to most women workers

(E) evidence of a trend toward a more modern wage system

25. The passage implies which of the following about women spinners in medieval Europe?

(A) Most of them worked independently for wealthy sponsors.

(B) They were not typical of medieval women entrepreneurs.

(D) They would have been able to contribute substantial amounts to their families incomes were it not for the prohibition against advancing money to them.

(E) They were inevitably disadvantaged in the marketplace because they were obliged to obtain money for their supplies from usurers.

26. The passage implies that feelings of hopelessness among medieval workers

(A) resulted primarily from the lack of a rational system of differential rewards

(B) disappeared completely once medieval textile workers were able to break the cycle of poverty

(D) came into being in part because of women’s limited earning capacity

(E) were particularly common among textile workers in Italy and France

27. The author suggests that historians have done which of the following?

(A) Failed to give adequate consideration to the economic contribution of women during the medieval period.

(B) Overestimated the degree of hopelessness experienced by medieval workers trapped in the poverty cycle.

(D) Regard the economic status of women in Italy and France as representative of women’s status throughout medieval Europe.

(E) Overlooked part of the significance of a prohibition governing one aspect of yarn production in medieval Europe.
