Passage 3
Federal efforts to aid minority businesses  began in the
1960’s  when the Small Business Administration (SBA)
began making federally guaranteed loans and govern-
ment-sponsored management and technical assistance
(5) available to minority business enterprises. While this
program  enabled many minority entrepreneurs to
form new businesses, the results were disappointing ,
since managerial inexperience, unfavorable locations,
and capital shortages led to high failure rates. Even  15
(10) years after the program was implemented, minority
business receipts were not quite two percent of the national
economy’s total receipts.15、16题
资助少数民族企业起源于1960年SBA。SBA结果不是很理想。甚至在15年后少数民族的收入都不及总收入的2%。
Recently  federal policymakers have adopted an
approach intended to accelerate development of the
(15) minority business sector by moving away from directly
aiding small minority enterprises and toward supporting
larger, growth-oriented minority firms through interme-
diary companies. In this approach , large corporations
participate in the development of successful and stable
(20) minority businesses by making use of government-
sponsored venture capital.14题 The capital is used by a
participating company to establish a Minority Enterprise
Small Business Investment Company or MESBIC . The
MESBIC then provides capital and guidance to minority
(25) businesses that have potential to become future suppliers
or customers of the sponsoring company.
MESBIC’s are the result of the belief that providing
established firms with easier access to relevant manage-
ment techniques and more job-specific experience, as
(30) well as substantial amounts of capital, gives those firms
a greater opportunity to develop sound business founda-
tions than does simply making general management
experience and small amounts of capital available.
Further,  since potential markets for the minority busi-
(35) nesses already exist through the sponsoring companies,
the minority businesses face considerably less risk in
terms of location and market fluctuation. Following
early financial and operating problems, sponsoring
corporations began to capitalize MESBIC’s far above
(40) the legal minimum of $500,000 in order to  generate
sufficient income and to sustain the quality of manage-
ment needed. MESBIC’c are now emerging as increas-
ingly important financing sources for minority enter-
prises.
近来，政府采用一种新方法资助少数民族企业，新方法从资助少数民族企业转向通过中间企业支持大的、增长为导向的企业。这种方法要求大企业参加。大企业用政府资助资金建立MESBIC. M为将来能成为大企业供应商或顾客的少数民族企业提供资金或管理支持。M帮助少数民族企业获得更好的管理能力，更多的资金等。进一步，由于市场已经存在，选址问题的危险更少。大企业提供的资金远高于政府规定的限额，M已成为少数民族企业的一项重要资金来源。
(45) Ironically , MESBIC staffs, which usually consist of
Hispanic and Black professionals, tend to approach
investments in minority firms more pragmatically than
do many MESBIC directors, who are usually senior
managers from sponsoring corporations. The latter
(50) often still think mainly in terms of the “social responsi-
bility approach” and thus seem to prefer deals that are
riskier and less attractive than normal investment criteria
would warrant. Such differences in viewpoint have pro-
duced uneasiness among many minority staff members,
(55) who feel that minority entrepreneurs and businesses
should be judged by established business considerations.
These staff members believe their point of view is closer
to the original philosophy of MESBIC’s and they are
concerned that, unless a more prudent course is fol-
lowed, MESBIC directors may revert to policies likely
to re-create the disappointing results of the original SBA
approach.
讽刺的是，M员工比领导者更有实用性。M领导者认为应该依照社会责任，他们更喜欢那些更危险利益小的企业。M员工认为这样会导致SBA的结果

Passage 12
All of the cells in a particular plant start out with the
same complement of genes. How then can these cells
differentiate and form structures as different as roots,
stems, leaves, and fruits?  The answer is that only a
(5) small subset of the genes in a particular kind of cell are
expressed, or turned on, at a given time. This is accom-
plished by a complex system of chemical messengers
that in plants include hormones and other regulatory
molecules.  71题Five major hormones have been identified:
(10) auxin, abscisic acid, cytokinin, ethylene, and gibberel-
lin. Studies of plants have now identified a new class of
regulatory molecules called oligosaccharins.
Unlike the oligosaccharins , the five well-known plant
hormones are pleiotropic rather than specific, that is,
(15) each has more than one effect on the growth and devel-
opment of plants 69题、70题. The five has so many simultaneous
effects that they are not very useful in artificially
controlling the growth of crops67题、72题. Auxin, for instance ,
stimulates the rate of cell elongation, causes shoots to
(20) grow up and roots to grow down, and inhibits the
growth of lateral shoots. Auxin also causes the plant to
develop a vascular system, to form lateral roots, and to
produce ethylene.
植物都起源于同一种基因的综合，为什么后来有的变成树叶、枝干、根？因为信息者使他们展现不同的细胞基因。这种信息者是由五种荷尔蒙和其他规范分子组成。五种荷尔蒙是…。科学家现在发现了一种新的规范分子小O。与小O不同的是，五种荷尔蒙比它更宽泛而不是具体，也就是对植物生长发育有多种的功能。这五种有很多功能，不一定都对人工控制植物生长有用。举个例子小A证明这一点。
The pleiotropy of the five well-studied plant
(25) hormones is somewhat analogous  to that of certain
hormones in animal. For example , hormones from the
hypothalamus in the brain stimulate the anterior lobe
of the pituitary gland to synthesize and release many
different hormones68题, one of which stimulates the release
(30) of hormones from the adrenal cortex. These hormones
have specific effects on target organs all over the body.
One hormone stimulates the thyroid gland, for
example , another the ovarian follicle cells, and so forth.
In other words , there is a hierarchy of hormones.
(35) Such a hierarchy  may also exist in plants . Oligosac-
charins are fragments of the cell wall released by
enzymes: different enzymes release different oligosac-
charins. There are indications that pleiotropic plant
hormones may actually function by activating the
(40) enzymes that release these other, more specific chemical
messengers from the cell wall. 68题
这种P的特性也类似存在于动物之中。举个例子，动物大脑中的荷尔蒙刺激并综合释放其他不同的荷尔蒙，这些荷尔蒙又可以释放其他部位的荷尔蒙。最后的这些荷尔蒙有对身体的器官有具体的功能。这就是荷尔蒙的世袭制度。这种世袭制度也存在于植物之中。小Ｏ就是由被其他酶释放出来的细胞墙的碎片，不同的酶产生不同的小Ｏ。小Ｐ（即五种荷尔蒙）可以刺激酶产生其他具体的化学信息者（即小Ｏ）。

Passage 17
Australian researchers have discovered electroreceptors
(sensory organs designed to respond to electrical fields)
clustered at the tip of the spiny anteater’s snout102题. The
researchers made this discovery by exposing small areas of
(5) the snout to extremely weak electrical fields and recording
the transmission of resulting nervous activity to the brain.
While it is true that  tactile receptors, another kind of
sensory organ on the anteater’s snout, can also respond to
electrical stimuli, such receptors do so only in response to
( 10) electrical field strengths about 1,000 times greater than
those known to excite electroreceptors.101题
科学家发现了电子接收器，在小a的鼻子尖端上。科学家通过什么实验过程证实这个发现。虽然小a鼻子上有另一种感觉器官小t也可以接受电流，但是它接受的电流的强度时电子接收器接受的100倍，排除是另一种感觉器官的可能性。
Having discovered the electroreceptors, researchers are
now investigating how anteaters utilize such a sophisticated
sensory system. In one behavioral experiment , researchers
(15) successfully trained an anteater to distinguish between
two troughs of water, one with a weak electrical field
and the other with none. Such evidence  is consistent with
researchers’ hypothesis  that anteaters use electroreceptors
to detect electrical signals given off by prey; however ,
( 20) researchers as yet have been unable to detect electrical
signals emanating from termite mounds, where the favorite
food of anteaters live. Still,  researchers have observed
anteaters breaking into a nest of ants at an oblique angle
and quickly locating nesting chambers. This ability quickly
(25)to locate unseen prey suggests, according to the researchers, that the anteaters were using their electroreceptors to locate the nesting chambers.105题
科学家开始调查小a是怎样利用电子接收器的。科学家通过一个实验…。实验证实科学家的推测小a通过电子接收器捕猎。然而科学家没有在一个小a喜欢的食物中发现电流。但是，科学家仍发现小a以斜角挖洞寻找看不见的蚂蚁洞穴，再次证明了小a利用电子接受器定位蚂蚁巢穴。

102. Which of the following can be inferred about the
experiment described in the first paragraph?
(A) Researchers had difficulty verifying the existence of
electroreceptors in the anteater because
electroreceptors respond to such a narrow range of

(B) Researchers found that the level of nervous activity
in the anteater’s brain increased dramatically as the
strength of the electrical stimulus was increased.（电流增加，神经活动增加错，电子接受器只对微弱电流有反应）
(C) Researchers found that some areas of the anteater’s
snout were not sensitive to a weak electrical
stimulus.（电子接收器只存在鼻子尖端，鼻子上其他部位对微弱电流没反应）
(D) Researchers found that the anteater’s tactile
receptors were more easily excited by a strong
electrical stimulus than were the electro receptors..（电子接收器仅对微弱电流有反应）

Passage 46
(This passage was written in 1984.)
It is now possible to hear a recording of Caruso’s singing that is far superior  to any made during
his lifetime. A decades-old way-cylinder recording of this great operatic tenor has been digitized,
and the digitized signal has been processed by computer to remove the extraneous sound, or
“noise,” introduced by the now “ancient” wax-cylinder recording process.
现在听C的音乐质量比他的时代更好。过去的录音可以被数字化，数字化的信号被的计算机除掉外来声音或噪音
Although this digital technique needs improvements, it represents a new and superior way  of
recording and processing sound which overcomes many of the limitations of analog recording. In
analog recording systems , the original sound is represented as a continuous waveform273题 created by
variations in the sound’s amplitude over time. When analog playback systems reproduce this
waveform, however , they invariably introduce distortions. First, the waveform produced during
playback differs somewhat from the original waveform. Second, the medium that stores the analog
recording creates noise during playback which gets added to the recorded sounds.
虽然数字化录音需要改进，但是它代表了一种新的更好的记录声音的方法，超越了以前的模拟录音。在模拟录音系统中，原来的声音是被连续的波形所表达。但是，当模拟系统复制信号时，不可避免的产生了失真。第一种是…，第二种是…。
Digital recordings , by contrast , reduce the original sound to a series of discrete numbers that
represent the sound’s waveform273题. Because the digital playback system “reads” only numbers, any noise and distortion that may accumulate during storage and manipulation of the digitized signal
will have little effect274题: as long as the numbers remain recognizable, the original waveform will be reconstructed with little loss in quality. However,  because the waveform is continuous, while its
digital representation is composed of discrete numbers, it is impossible for digital systems to avoid
some distortion275题. One kind of distortion , called “sampling error,” occurs if the sound is sample (i.e., its amplitude is measured) too infrequently, so that the amplitude changes more than one quantum(the smallest change in amplitude measured by the digital system) between samplings. In effect,the sound is changing too quickly for the system to record it accurately. A second form  of
distortion is “quantizing error,” which arises when the amplitude being measured is not a whole
number of quanta, forcing the digital recorder to round off. Over the long term, these errors are
random, and the noise produced (a background buzzing) is similar to  analog noise except that it
only occurs when recorded sounds are being reproduced.
相反的是，数字录音将原来声音降低为一系列的代表波形数字。因为数字录音系统读取数字，所以一些在存储运作中产生的噪音和失真不会产生任何影响：只要原有数字仍可识别，原来的波形就可以被重建。但是，因为波形是连续的，而数字是分离的，所以就不可避免的产生两种失真。第一种失真，…。第二种失真…。
analog ['ænəlɔɡ] n. 类似物；模拟 adj. 有长短针的；模拟的
distortion [dis'tɔ:ʃən] n. 变形；扭曲；曲解；失真

Passage 1
Caffeine , the stimulant in coffee, has been called
“the most widely used psychoactive substance on Earth .”
Synder, Daly and Bruns  have recently proposed  that
caffeine affects behavior by countering the activity in
(5) the human brain of a naturally occurring chemical called
adenosine.  Adenosine normally depresses neuron firing
in many areas of the brain. It apparently does this by
inhibiting the release of neurotransmitters2题, chemicals
that carry nerve impulses from one neuron to the next .
(10) Like many other agents that affect neuron firing,
adenosine must first bind to specific receptors on
neuronal membranes. There are at least two classes
of these receptors, which have been designated A1 and
A2.  Snyder et al propose  that caffeine, which is struc-
(15) turally similar to  adenosine5题, is able to bind to both types
of receptors, which prevents adenosine from attaching
there and allows the neurons to fire more readily than
they otherwise would2题.
S人物认为Caffeine是通过counter于小A起作用的小A的作用原理是绑定在A1A2上S认为Caffeine在结构上与小A类似，从而代替了小A绑定而起作用。
For many years , caffeine’s effects have been attri-
(20) buted to its inhibition of the production of phosphodi-
esterase , an enzyme that breaks down the chemical
called cyclic AMP .A number of neurotransmitters exert
their effects by first increasing cyclic AMP concentra-
tions in target neurons. Therefor e, prolonged periods at
(25) the elevated concentrations, as might be brought about
by a phosphodiesterase inhibitor, could lead to a greater
amount of neuron firing and, consequently, to behav-
ioral stimulation. But Snyder et al point out  that the
caffeine concentrations needed to inhibit the production
(30) of phosphodiesterase in the brain are much higher than
those that produce stimulation. Moreover , other com-
pounds that block phosphodiesterase’s activity are not
stimulants.
老观点：以前认为咖啡因是阻止小p生产来起作用的。说了一大堆原理怎么阻止小p生产起作用。但是S反驳说这种观点不对，因为需要咖啡因阻止小p的浓度比能刺激它的要高。另外，也没有发现其他阻止小p的刺激物。
既然出现了老理论，一定会出现对老理论的反驳。所以老理论本身内容不重要，如何反驳才是最重要的。这里的BUT要注意，but后出现了S人物，又出现了point out，大家就知道，这里就是S对于老理论的反驳了。后面又出现了一个Moreover，说明是S人物进一步的阐述――从这里可以看出GMAT阅读文章论述上的严谨：从一个角度反驳不够，还会从另外一个角度增加反驳的力度和严谨性。
本段有几个语言现象是值得注意的：1.therefore和consequently，表示顺接总结上面的意思，就说明还是在说老理论，时间非常紧张的时候就可以略过不读，当然我本人建议能读都要读，帮助理解也帮助理清逻辑关系；2. for many years表示老理论内容；3. but转折后出现了S人物和point out，说明S要开始反驳了，要特别注意反驳的内容。4. Moreover说明是S反驳的另外一个角度。
To buttress  their case that caffeine acts instead by pre-
(35) venting adenosine binding, Snyder et al compared the
stimulatory effects of a series of caffeine derivatives with
their ability to dislodge adenosine from its receptors in
the brains of mice.  “In general,”  they reported, “the
ability of the compounds to compete at the receptors
(40) correlates with their ability to stimulate locomotion in
the mouse; i.e.,  the higher their capacity to bind at the
receptors, the higher their ability to stimulate locomo-
tion.” Theophylline , a close structural relative of caffeine
and the major stimulant in tea, was one of the most
(45) effective compounds in both regards.
To buttress…所以做实验实验总结in general说…举例来说，小T…
本段出现的新名词是小T。
再次赞叹GMAT逻辑的严密：反驳老理论还不够，必须通过实践来支持其反驳。实验结果证实了S的理论。这还不够，又通过一个类似的小T的例子加强说明。
There were some apparent exceptions to the general
correlation observed between adenosine-receptor binding
and stimulation. One of these was a compound called
3-isobuty1-1-methylxanthine(IBMX), which bound very
(50) well but actually depressed mouse locomotion. Snyder
et al suggest that  this is not a major stumbling block to
their hypothesis. The problem is that the compound has
mixed effects in the brain, a not unusual occurrence with
psychoactive drugs3题. Even  caffeine, which is generally
(55) known only for its stimulatory effects, displays this
property, depressing mouse locomotion at very low
concentrations and stimulating it at higher ones.
存在例外比如IBMXS解释说…况且…
最后一段也很简单，这也是GMAT文章很普遍的一个现象：为了表示其理论的严谨性，通常作者一会一杆子打死所有反驳，他会承认，的确是有例外的，但是这些例外是可以解释的――不用我说， S解释的内容才是本段的重点。
从这里再次看到，S反驳永远通过两个方面来进行，逻辑极其严密。

buttress ['bʌtris] n.支撑物vt.支持

dislodge [dis'lɔdʒ] vt. 逐出，驱逐；使……移动；用力移动vi. 驱逐，逐出；离开原位

逻辑简图：第一段引出咖啡因。S提出咖啡因是通过反作用于小a来起作用的。提出原理——第二段提出老观点说咖啡因是通过抑制小p生产的，但是S反驳了这种观点。——第三段通过实验证明S提出的观点，提出例子小t  ——第四段说有一些例外，但可以解释。

Passage 19
Seeking  a competitive advantage115题, some professional
service firms(for example, firms providing advertising,
accounting, or health care services)  have considered
offering unconditional guarantees of satisfaction. Such
(5) guarantees  specify what clients can expect and what the
firm will do if it fails to fulfill these expectations.
Particularly with first-time clients, an unconditional
guarantee can be an effective  marketing tool if the
client is very cautious, the firm’s fees are high, the
(10) negative consequences of bad service are grave, or
business is difficult to obtain through referrals and
word-of-mouth.114题
专业服务公司提供无条件保证。无条件保证是…..。无条件保证在…情况下是有效的。
However,  an unconditional guarantee can sometimes
hinder  marketing efforts. With its implication that fail-
(15) ure is possible, the guarantee may, paradoxically, cause
clients to doubt the service firm’s ability to deliver the
promised level of service117题. It may conflict with a firm’s
desire to appear sophisticated, or may even suggest that
a firm is begging for business. In legal and health care
(20) services, it may mislead clients by suggesting that law-
suits or medical procedures will have guaranteed out-
comes 116题. Indeed , professional service firms with outstandin
reputations and performance to match have little to gain
from offering unconditional guarantees. And any firm
(25) that implements an unconditional guarantee without
undertaking a commensurate commitment to quality of
service is merely employing a potentially costly
marketing gimmick.
然而，无条件保证阻碍了市场努力。后面一些列排比说怎么阻碍的。

Passage 21
Two modes of argumentation have been used on
behalf of women’s emancipation in Western societies.
Arguments in what could be called the “relational”
feminist tradition maintain the doctrine of “equality in
(5) difference,” or equity as distinct for equality. They
posit  that biological distinctions between the sexes
result in a necessary sexual division of labor in the
family and throughout society and that women’s pro-
creative labor is currently undervalued by society, to
(10) the disadvantage of women. By contrast,  the individual-
ist feminist tradition  emphasizes  individual human rights
and celebrates women’s quest for personal autonomy,
while downplaying  the importance of gender roles and
minimizing  discussion of childbearing and its attendant
(15) responsibilities.
有两种关于妇女革命的论断。一种是关系理论.解释关系理论是…。另一种是私人主义理论。私人主义理论是…，但其忽视了关系理论强调的内容。
Before the late nineteenth century , these views
coexisted within the feminist movement, often within
the writings of the same individual. Between 1890 nd
1920 , however , relational feminism, which had been the
(20) dominant strain in feminist thought, and which still pre-
dominates among European and non-Western feminists129题,
lost ground in England and the United States. Because
the concept of individual rights was already well estab-
lished in the Anglo-Saxon legal and political tradition,
(25) individualist feminism came to predominate in English-
speaking countries125题. At the same time , the goals of the
two approaches began to seem increasingly irreconcil-
able . Individualist feminists began to advocate a totally
gender-blind system with equal rights for all. Relational
(30) feminists, while agreeing that  equal educational and
economic opportunities outside the home should be avail-
able for all women128题, continued to emphasize women’s
special contributions to society as homemakers and
mothers; they demanded special treatment
(35) including protective legislation for women workers,
state-sponsored maternity benefits, and paid compensa-
tion for housework.
18世纪以前，两种观点是协调的。在1890-1920年中，英国和美国放弃了关系理论支持个人主义理论,因为…。同时个人主义理论和关系理论越来越不可协调的。个人主义理论是。。。关系理论是。。。。
Relational arguments have a major pitfall : because
they underline women’s physiological and psychological
(40) distinctiveness, they are often appropriated by political
adversaries and used to endorse male privilege126题. But  the
individualist approach, by attacking gender roles, deny-
ing the significance of physiological difference127题, and
condemning existing familial institutions as hopelessly
(45) patriarchal, has often simply treated as irrelevant the
family roles important to many women. If the individu-
alist framework, with its claim for women’s autonomy,
could be harmonized with the family-oriented concerns
of relational feminists, a more fruitful model for con-
(50) temporary feminist politics could emerge.

Passage 45
Maps made by non-Native Americans to depict Native American land tenure, resources and
population distributions appeared almost as early as Europeans’ first encounters with Native
Americans and took many form: missionaries’ field sketches, explorers’ drawings, and surveyors’
maps, as well as maps rendered in connection with treaties involving land transfers . Most existing
maps of Native American lands are reconstructions that are based largely on archaeology, oral
reports, and evidence gathered from observers’ accounts in letter, diaries, and official reports ;
accordingly , the accuracy of these maps is especially dependent on the mapmakers’ own
interpretive abilities.270题、271题
由非美洲原住民描述的美洲地图在…时间出现，有…形式。这些地图重现构建依照….形式，因此地图反映了画地图者的解释能力。
Many existing maps also  reflect the 150-year role of the Bureau of Indian Affairs (BIA) in
administering tribal lands. Though these maps incorporate some information gleaned directly from
Native Americans, rarely has Native American cartography contributed to this official record ,
which has been compiled, surveyed, and authenticated by non-Native American. Thus  our current cartographic record relating to Native American tribes and their migrations and cultural features, as well as territoriality and contemporary trust lands, reflects the origins of the data, the mixed purposes for which the maps have been prepared, and changes both in United States government policy and in non-Native Americans’ attitudes toward an understanding 269题
of Native Americans.
地图同时反映了BIA管理土地的角色。虽然地图与美洲本土居民的信息不相同，但是美洲本土居民的绘图法对官方数据几乎没有贡献，这些官方数据是由非本土美洲居民汇集的；因此我们现在的关于美洲部落民族、移民、文化元素以及领土、同时代的土地的相关制图记录反映了数据的来源，准备地图的综合目的，以及美国政府政策的转变和非本土美洲居民对本土美洲居民的理解态度的转变等。

Passage 7
In 1896 a Georgia couple suing for damages in the
accidental death of their two year old was told that since
the child had made no real economic contribution to the
family37题, there was no liability for damages. In contrast ,
(5) less than a century later, in 1979 , the parents of a three
year old sued in New York for accidental-death damages
and won an award of $750,000.
The transformation in social values implicit in juxta-
posing these two incidents is the subject of Viviana
(10) Zelizer’s excellent  book, Pricing the Priceless Child.
During the nineteenth century, she argues , the concept
of the “useful” child who contributed to the family
economy38题 gave way gradually to the present-day notion
of the “useless” child who, though producing no income
(15) for, and indeed extremely costly to, its parents38题E, is yet
considered emotionally “priceless.” Well established
among segments of the middle and upper classes by the
mid-1800’s , this new view of childhood spread through-
out society in the late-nineteenth and early-twentieth
(20) centuries as  reformers introduced child-labor regulations
and compulsory education laws predicated  in part on the
assumption that a child’s emotional value made child
labor taboo.
For Zelizer  the origins of this transformation were
(25) many and complex. The gradual erosion of children’s
productive value in a maturing industrial economy,
the decline in birth and death rates, especially in child
mortality, and the development of the companionate
family (a family in which members were united by
(30) explicit bonds of love rather than duty)41、42题  were all factors
critical in changing the assessment of children’s worth.
Yet  “expulsion of children from the ‘cash nexus,’...
although clearly shaped by profound changes in the
economic, occupational, and family structures,” Zelizer
(35) maintains.  “was also part of a cultural process ‘of sacral-
ization’ of children’s lives. ” Protecting children from the
crass business world became enormously important for
late-nineteenth-century middle-class Americans, she
suggests ; this sacralization was a way of resisting what
(40) they perceived as the relentless corruption of human
values by the marketplace.
In stressing the cultural determinants of a child’s
worth. Zelizer takes issue with  practitioners of the new
“sociological economics,”  who have analyzed such tradi-
(45) tionally sociological topics as crime, marriage, educa-
tion, and health solely in terms of their economic deter-
minants. Allowing only a small role for cultural forces
in the form of individual “preferences,” these sociologists
tend to view  all human behavior as directed primarily by
(50) the principle of maximizing economic gain. Zelizer is
highly critical  of this approach, and emphasizes instead
the opposite phenomenon:  the power of social values to
transform price. As children became more valuable in
emotional terms, she argues , their “exchange” or “ sur-
(55) render” value on the market, that is, the conversion of
their intangible worth into cash terms, became much
greater.
