1、GMAT Sentences:No. 001Civil rights activists have long argued that one of the principal reasons the Blacks, Hispanics, and other minority groups have difficulty establishing themselves in business is that they lack access to the sizable orders and subcontracts that are generated by large companies.N
2、o. 002Fascination with this ideal has made Americans defy the “Old World” categories of settled possessiveness versus unsettling deprivation, the cupidity of retention versus the cupidity of seizure, a “status quo” defended or attacked.No. 003The nonstarters were considered the ones who wanted stabi
3、lity, a strong referee to give them some position in the race, a regulative hand to calm manic speculation; an authority that can call things to a halt, begin things again from compensatorily staggered “starting lines.”No. 004“Reform” in America has been sterile because it can imagine no change exce
4、pt through the extension of this metaphor of a race, wider inclusion of competitors, “a piece of the action,” as it were, for the disenfranchised.No. 005We have no pride in our growing interdependence, in the fact that our system can serve others, that we are able to help those in need; empty boasts
5、 from the past make us ashamed of our present achievements, make us try to forget or deny them, move away from them.No. 006The traditional view supposes that the upper mantle of the earth behaves as a liquid then it is subjected to small forces for long periods and that differences in temperature un
6、der oceans and continents are sufficient to produce convection in the mantle of the earth with rising convection currents under the mid-ocean ridges and sinking currents under the continents.No. 007This view may be correct: it has the advantage that the currents are driven by temperature differences
7、 that themselves depend on the position of the continents.No. 008The enclosed seas are an important feature of the earths surface and seriously require explanation because, in addition to the enclosed seas that are developing at present behind islands arcs, there are a number of older ones of possib
8、ly similar origin, such as the Gulf of Mexico, the Black Sea, and perhaps the North Sea.No. 009Furthermore, neutrinos carry with them information about the site and circumstances of their production: therefore, the detection of cosmic neutrinos could provide new information about a wide variety of c
9、osmic phenomena and about the history of the universe.No. 010Consequently, nothing seems good or normal that does not accord with the requirements of the free market.No. 011Accordingly, it requires a major act of will to think of price-fixing (the determination of prices by the seller) as both “norm
10、al” and having a valuable economic function.No. 012In fact, price-fixing is normal in all industrialized societies because the industrial system itself provides, as an effortless consequence of its own development, the price-fixing that it requires.No. 013That each large firm will act with considera
11、tion of its own needs and thus avoid selling its products for more that its competitors charge is commonly recognized by advocates of free-market economic theories.No. 014Moreover, those economists who argue that allowing the free market to operate without interference is the most efficient method o
12、f establishing prices have not considered the economies of nonsocialist countries other than the United States.No. 015Synder, Daly, and Bruns have recently proposed that caffeine affects behavior by countering the activity in the human brain of a naturally occurring chemical called adenosine.No. 016
13、To buttress their case that caffeine acts instead by preventing 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.No. 017The problem is that the compound has mixed eff
14、ects in the brain, a not unusual occurrence with psychoactive drugs.No. 018Who would want an unmarked pot when another was available whose provenance was known, and that was dated stratigraphically by the professional archaeologist who excavated it?No. 019Federal efforts to aid minority businesses b
15、egan in the 1960s when the Small Business Administration (SBA) began making federally guaranteed loans and government-sponsored management and technical assistance available to minority business enterprises.No. 020Recently federal policymakers have adopted an approach intended to accelerate developm
16、ent of the minority business sector by moving away from directly aiding small minority enterprises and toward supporting larger, growth-oriented minority firms through intermediary companies.No. 021MESBICs are the result of the belief that providing established firms with easier access to relevant m
17、anagement techniques and more job-specific experience, as well as substantial amounts of capital, gives those firms a greater opportunity to develop sound business foundations that does simply making general management experience and small amounts of capital available.No. 022Most senior executives a
18、re familiar with the formal decision analysis models and tools, and those who use such systematic methods for reaching decisions are occasionally leery of solutions suggested by these methods which run counter to their sense of the correct course of action.No. 023But the debate could not be resolved
19、 because no one was able to ask the crucial questions in a form in which they could be pursued productively.No. 024During the nineteenth century, she argues, the concept of the “useful” child who contributed to the family economy gave way gradually to the present-day notion of the “useless” child wh
20、o, though producing no income for, and indeed extremely costly to, its parents, is yet considered emotionally “priceless.”No. 025Well established among segments of the middle and upper classes by the mid-1800s, this new view of childhood spread throughout society in the late-nineteenth and early-twe
21、ntieth centuries as reformers introduced child-labor regulations and compulsory education laws predicated in part on the assumption that a childs emotional value made child labor taboo.No. 026“Expulsion of children from the cash nexus although clearly shaped by profound changes in the economic, occu
22、pational, and family structures,” Zelizer maintains, “was also part of a cultural process of sacralization of childrens lives.”No. 027Protecting children from the crass business world became enormously important for late-nineteenth-century middle-class Americans, she suggest; this sacralization was
23、a way of resisting what they perceived as the relentless corruption of human values by the marketplace.No. 028The factors favoring unionization drives seem to have been either the presence of large numbers of workers, as in New York City, to make it worth the effort, or the concentration of small nu
24、mbers in one or two locations, such as a hospital, to make it relatively easy.No. 029Individual entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing from commercial resources.No. 030Since large bees are not affected by the spraying of Matacil, these results
25、 add weight to the argument that spraying where the pollinators are sensitive to the pesticide used decreases plant fecundity.No. 031The question of whether the decrease in plant fecundity caused by the spaying of pesticides actually causes a decline in the overall population of flowering plant spec
26、ies still remains unanswered.No.032Although at first the colonies held little positive attraction for the English they would rather have stayed home by the eighteenth century people increasingly migrated to America because they regarded it as the land of opportunity.No. 033If the competitor can prov
27、e injury from the imports and that the United States company received a subsidy from a foreign government to build its plant abroad the United States companys products will be uncompetitive in the United States, since they would be subject to duties.No. 034In addition many ethnologists at the turn o
28、f the century believed that Native American manners and customs were rapidly disappearing, and that it was important to preserve for posterity as much information as could be adequately recorded before the cultures disappeared forever.No. 035In such a context, what is recognized as “dependency” in W
29、estern psychiatric terms is not, in Korean terms, an admission of weakness or failure.No. 036And managers under pressure to maximize cost-cutting will resist innovation because they know that more fundamental changes in processes or systems will wreak havoc with the results on which they are measure
30、d.No. 037Most novelists and historians writing in the early to mid-twentieth century who considered women in the West, when they considered women at all, fell under Turners spell.No. 038In addition, the ideal of six CEOs (female or male) serving on the board of each of the largest corporations is re
31、alizable only if every CEO serves on six board.No. 039Increasingly, historians are blaming diseases imported from the Old World for the staggering disparity between the indigenous population of America in 1492 new estimates of which soar as high as 100 million, or approximately one-sixth of the huma
32、n race at that time and the few million full-blooded Native Americans alive at the end of the nineteenth century.No. 040Virgin-soil epidemics are those in which the populations at risk have had no previous contact with the diseases that strike them and are therefore immunologically almost defenseles
33、s.No. 041Spanish tribute records The evidence provided by the documents of British and French colonies is not as definitive because the conquerors of those areas did not establish permanent settlements and begin to keep continuous records until the seventeenth century, by which time the worst epidem
34、ics had probably already taken place.No. 042Unfortunately, the documentation of these and other epidemics is slight and frequently unreliable, and it is necessary to supplement what little we do know with evidence from recent epidemics among Native Americans.No. 043Scientists have begun to suspect t
35、hat this intergalactic gas is probably a mixture of gases left over from the “big bang” when the galaxies were formed and gas was forced out of galaxies by supernova explosions.No. 044He noted that the wavelengths of the radiation emitted by a gas would change as the gas cooled, so that as the gas f
36、lowed into the galaxy and became cooler, it would emit not x-rays, but visible light, like that which was captured in the photographs.No. 045Transported outside the nucleus to the cytoplasm, the mRNA is translated into the protein it encodes by an organelle known as a ribosome, which strings togethe
37、r amino acids in the order specified by the sequence of elements in the mRNA molecule.No. 046However, recent investigations have shown that the concentrations of most mRNAs correlate best, not with their synthesis rate, but rather with the equally variable rates at which cells degrade the different
38、mRNAs in their cytoplasm.No. 047If a cell degrades both a rapidly and a slowly synthesized mRNA slowly, both mRNAs will accumulate to high levels.No. 048For instance, the mass-production philosophy of United States automakers encouraged the production of huge lots of cars in order to utilize fully e
39、xpensive, component-specific equipment and to occupy fully workers who have been trained to execute one operation efficiently.No. 049Japanese automakers chose to make small-lot production feasible by introducing several departures from United States practices, including the use of flexible equipment
40、 that could be altered easily to do several different production tasks and the training of workers in multiple jobs.No. 050Automakers could schedule the production of different components or models on single machines, thereby eliminating the need to store the buffer stocks of extra components that r
41、esult when specialized equipment and workers are kept constantly active.No. 051In recent studies, however, we have discovered that the production and release in brain neurons of the neurotransmitter serotonin (neurotransmitters are compounds that neurons use to transmit signals to other cells) depen
42、d directly on the food that the body processes.No. 052Our first studies sought to determine whether the increase in serotonin observed in rats given a large injection of the amino acid tryptophan might also occur after rats ate meals that change tryptophan levels in the blood.No. 053The consumption
43、of protein increases blood concentration of the other amino acids much more, proportionately, than it does that of tryptophan.No. 054The revisionist view of Jim Crow legislation grew in part from the research that Woodward had done for the NAACP legal campaign during its preparation for Brown v. Boa
44、rd of Education.No. 055Woodward confessed with ironic modesty that the first edition “had begun to suffer under some of the handicaps that might be expected in a history of the American Revolution published in 1776.”No. 056Yet, like Paine, Woodward had an unerring sense of the revolutionary moment,
45、and of how historical evidence could undermine the mythological tradition that was crushing the dreams of new social possibilities.No. 057Joseph Glarthaars Forged in Battle is not the first excellent study of Black soldiers and their White officers in the Civil War, but it uses more soldiers letters
46、 and diaries including rare material from Black soldiers and concentrates more intensely on Black-While relations in Black regiments that do any of its predecessors.No. 058While perhaps true of those officers who joined Black units for promotion or other self-serving motives, this statement misrepre
47、sents the attitudes of the many abolitionists who became officers in Black regiments.No. 059Moreover, arguments pointing out the extent of both structural and functional differences between eukaryotes and true bacteria convinced many biologists that the precursors of the eukaryotes must have diverge
48、d from the common ancestor before the bacteria arose.No. 060New techniques for determining the molecular sequence of the RNA of organisms have produced evolutionary information about the degree to which organisms are related, the time since they diverged from a common ancestor, and the reconstructio
49、n of ancestral versions of genes.No. 061These techniques have strongly suggested that although the true bacteria indeed form a large coherent group, certain other bacteria, the archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct evolutionary branch that far antedates the common ancestor of all true bacteria.No. 062The new tax law allowed corporations to deduct the cost of the product donated plus half the difference between cost and fair market selling price, with the proviso that deductions cannot exceed twice
