Specifically, this analysis indicates that support networks play a critical role in starting and maintaining minority business enterprises by providing owners with a range of assistance, from the informal encouragement of family members and friends to dependable sources of la bor and clientele from the owner’s ethnic group (ethnic group: n.同种同文化之民族). Such self-help networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” institutions, those closest to the individual in shaping his or her behavior and beliefs. They are characterized by the face-to-face association and cooperation of persons united by ties of mutual concern. They form an intermediate social level between the individual and larger “secondary” institutions based on impersonal relatio nships. Primary institutions comprising the support network include kinship, peer, and neighborhood or community subgroups.A major function of self-help networks is financial support. Most scholars agree that minority business owners have depended primarily on family funds and ethnic community resources for investment capital. Personal savings have been accumulated, often through frugal living habits that require sacrifices by the entire family and are thus a product of long-term family financial behavior. Additional loans and gifts from relatives, forthcoming because of group obligation rather than narrow investment calculation, have supplemented personal savings. Individual entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing from commercial resources. They may actually avoid banks because they assume that commercial institutions either cannot comprehend the special needs of minority enterprise or charge unreasonably high interest rates.Within the larger ethnic community, rotating credit associations have been used to raise capital. These associations are informal clubs of friends and other trusted members of the ethnic group who make regular contributions to a fund that is given to each contributor in rotation. One author estimates that 40 percent of New York Chinatown firms established during 1900-1950 utilized such associations as their initial source of capital. However, recent immigrants and third or fourth generations of older groups now employ rotating credit associations only occasionally to raise investment funds. Some groups, like Black Americans, found other means of financial support for their entrepreneurial efforts. The first Black-operated banks were created in the late nineteenth century as depositories (depository: n.存放处) for dues (due: n. [复]应付款) collected from fraternal or lodge groups, which themselves had sprung from Black churches. Black banks madelimited investments in other Black enterprises. Irish immigrants in American cities organized many building and loan associations to provide capital for home construction and purchase. They, in turn, provided work for many Irish home-building contractor firms. Other ethnic and minority groups followed similar practices in founding ethnic-directed financial institutions.1. Based on the information in the passage, it would be LEAST likely for which of the following persons to be part of a self-help network?(A) The entrepreneur’s childhood friend(B) The entrepreneur’s aunt(C) The entrepreneur’s religio us leader(D) The entrepreneur’s neighbor(E) The entrepreneur’s banker2. Which of the following illustrates the working of a self-help support network, as such networks are described in the passage?(A) A public high school offers courses in book-keeping and accounting as part of itsopen-enrollment adult education program.(B) The local government in a small city sets up a program that helps teen-agers find summer jobs.(C) A major commercial bank offers low-interest loans to experienced individuals who hope to establish their own businesses.(D) A neighborhood-based fraternal organization develops a program of on-the-job (on-the-job: adj.在职的) training for its members and their friends.(E) A community college offers country residents training programs that can lead to certification ina variety of technical trades.3. Which of the following can be inferred from the passage about rotating credit associations?(A) They were developed exclusively by Chinese immigrants.(B) They accounted for a significant portion of the investment capital used by Chinese immigrants in New York in the early twentieth century.(C) Third-generation members of an immigrant group who started businesses in the 1920’s would have been unlikely to rely on them.(D) They were frequently joint endeavors by members of two or three different ethnic groups.(E) Recent immigrants still frequently turn to rotating credit associations instead of banks for investment capital.4. The passage best supports which of the following statements?(A) A minority entrepreneur who had no assistance from family members would not be able to start a business.(B) Self-help networks have been effective in helping entrepreneurs primarily in the last 50 years.(C) Minority groups have developed a range of alternatives to standard financing of business ventures.(D) The financial institutions founded by various ethnic groups owe their success to their unique formal organization.(E) Successful minority-owned businesses succeed primarily because of the personal strengths of their founders.5. Which of the following best describes the organization of the second paragraph?(A) An argument is delineated, followed by a counter-argument.(B) An assertion is made and several examples are provided to illustrate it.(C) A situation is described and its historical background is then outlined.(D) An example of a phenomenon is given and is then used as a basis for general conclusions.(E) A group of parallel incidents is described and the distinctions among the incidents are then clarified.6. According to the passage, once a minority-owned business is established, self-help networks contribute which of the following to that business?(A) Information regarding possible expansion of the business into nearby communities(B) Encouragement of a business climate that is nearly free of direct competition(C) Opportunities for the business owner to reinvest profits in other minority-owned businesses(D) Contact with people who are likely to be customers of the new business(E) Contact with minority entrepreneurs who are members of other ethnic groups7. It can be inferred from the passage that traditional analyses of minority business would be LEAST likely to do which of the following?(A) Examine businesses primarily in their social contexts(B) Focus on current, rather than historical, examples of business enterprises(C) Stress common experiences of individual entrepreneurs in starting businesses(D) Focus on the maintenance of businesses, rather than means of starting them(E) Focus on the role of individual entrepreneurs in starting a business8. Which of the following can be inferred from the passage about the Irish building and loan associations mentioned in the last paragraph?(A) They were started by third- or fourth-generation immigrants.(B) They originated as offshoots of church-related groups.(C) They frequently helped Irish entrepreneurs to finance business not connected with construction.(D) They contributed to the employment of many Irish construction workers.(E) They provided assistance for construction businesses owned by members of other ethnic groups.参考答案:EDBC BDAD此外,为大家分享两种GMAT阅读技巧:一.TS的寻找方式1.套路结构法:A.现象解释型文章:文章开始给出现象,之后必定有解释,TS在解释给出处。

GMAT考试阅读试题(一)(5)

Passage 5 How many really suffer as a result of labor mar-ket problems? This is one of the most critical yetcontentious social policy questions. In many ways,our social statistics exaggerate the degree of hard-(5) ship. Unemployment does not have the same direconsequences today as it did in the 1930‘s whenmost of the unemployed were primary breadwin-ners,when income and earnings were usually muchcloser to the margin of subsistence, and when there(10) were no countervailing social programs for thosefailing in the labor market. Increasing affluence, therise of families with more than one wage earner, thegrowing predominance of secondary earners amongthe unemployed, and improved social welfare pro-(15) tection have unquestionably mitigated the conse-quences of joblessness. Earnings and income dataalso overstate the dimensions of hardship. Amongthe millions with hourly earnings at or below theminimum wage level, the overwhelming majority(20) are from multiple-earner, relatively affluent families. Most of those counted by the povertystatistics are elderly or handicapped or have familyresponsibilities which keep them out of the laborforce, so the poverty statistics are by no means an(25) accurate indicator of labor market pathologies. Yet there are also many ways our social statisticsunderestimate the degree of labor-market-relatedhardship. The unemployment counts exclude themillions of fully employed workers whose wages are(30) so low that their families remain in poverty. Lowwages and repeated or prolonged unemploymentfrequently interact to undermine the capacity forself-support. Since the number experiencing jobless-ness at some time during the year is several times(35)the number unemployed in any month, those whosuffer as a result of forced idleness can equal orexceed average annual unemployment, even thoughonly a minority of the jobless in any month reallysuffer. For every person counted in the monthly(40) unemployment tallies, there is another workingpart-time because of the inability to find full-timework, or else outside the labor force but wanting ajob. Finally, income transfers in our country havealways focused on the elderly,disabled, and depen-(45)dent, neglecting the needs of the working poor, sothat the dramatic expansion of cash and in-kindtransfers does not necessarily mean that those fail-ing in the labor market are adequately protected.As a result of such contradictory evidence, it is(50) uncertain whether those suffering seriously as aresult of thousands or the tens of millions, and,hence, whether high levels of joblessness can be tol-erated or must be countered by job creationand(55) economic stimulus. There is only one area of agree-ment in this debate——that the existingpoverty,employment, and earnings statistics are inadequatefor one their primary applications, measuring theconsequences of labor market problems.1. Which of the following is the principal topic of the passage? (A) What causes labor market pathologies that result in suffering (B) Why income measures are imprecise in measuring degrees of poverty (C) Which of the currently used statistical procedures are the best for estimating the incidence of hardship that is due to unemployment (D) Where the areas of agreement are among poverty, employment, and earnings figures (E) How social statistics give an unclear picture of the degree of hardship caused by low wages and insufficient employment opportunities2. The author uses “labor market problems” in lines 1-2 to refer to which of the following? (A) The overall causes of poverty (B) Deficiencies in the training of the work force (C) Trade relationships among producers of goods (D) Shortages of jobs providing adequate income (E) Strikes and inadequate supplies of labor3. The author contrasts the 1930‘s with the present in order to show that (A) more people were unemployed in the 1930‘s (B) unemployment now has less severe effects (C) social programs are more needed now (D) there now is a greater proportion of elderly and handicapped people among those in poverty (E) poverty has increased since the 1930‘s4.Which of the following proposals best responds to the issues raised by the author? (A) Innovative programs using multiple approachesshould be set up to reduce the level ofunemployment. (B) A compromise should be found between the positions of those who view joblessness as an evil greater than economic control and those who hold the opposite view. (C) New statistical indices should be developed to measure the degree to which unemployment and inadequately paid employment cause suffering. (D) Consideration should be given to the ways in whichstatistics can act as partial causes of the phenomenathat they purport to measure. (E) The labor force should be restructured so that itcorresponds to the range of job vacancies.5.The author‘s purpose in citing those who are repeatedly unemployed during a twelve-month period is most probably toshow that (A) there are several factors that cause the payment of low wages to some members of the labor force (B) unemployment statistics can underestimate the hardship resulting from joblessness (C) recurrent inadequacies in the labor market can exist and can cause hardships for individual workers (D) a majority of those who are jobless at any one time to not suffer severe hardship (E) there are fewer individuals who are without jobs at some time during a year than would be expected on the basis of monthly unemployment figures6. The author states that the mitigating effect of social programs involving income transfers on the income level of low-income people is often not felt by (A) the employed poor (B) dependent children in single-earner families (C) workers who become disabled (D) retired workers (E) full-time workers who become unemployed 7. According to the passage, one factor that causes unemployment and earnings figures to overpredict the amount of economic hardship is the (A) recurrence of periods of unemployment for a group of low-wage workers (B) possibility that earnings may be received from more than one job per worker (C) fact that unemployment counts do not include tose who work for low wages and remain poor (D) establishment of a system of record-keeping that makes it possible to compile poverty statistics (E) prevalence, among low-wage workers and the unemployed, of members of families in which others are employed8. The conclusion stated in lines 33-39 about the number of people who suffer as a result of forced idleness depends primarily on the point that (A) in times of high unemployment, there are some people who do not remain unemployed for long (B) the capacity for self-support depends on receiving moderate-to-high wages  (C) those in forced idleness include, besides the unemployed, both underemployed part-time workers and those not actively seeking work (D) at different times during the year, different people are unemployed (E) many of those who are affected by unemploy-ment are dependents of unemployed workers9. Which of the following, if true, is the best criticism of the author‘s argument concerning why poverty statistics cannot properly be used to show the effects of problems in the labor market? (A) A short-term increase in the number of those in poverty can indicate a shortage of jobs because the basic number of those unable to accept employment remains approximately constant. (B) For those who are in poverty as a result of joblessness, there are social programs available that provide a minimum standard of living. (C) Poverty statistics do not consistently agree with earnings statistics, when each is taken as a measure of hardship resulting from unemployment. (D) The elderly and handicapped categories include many who previously were employed in the labor market. (E) Since the labor market is global in nature, poor workers in one country are competing with poor workers in another with respect to the level of wages and the existence of jobs.。

2022年10-11月GMAT阅读真题(至11.7)(六)1.1.11 公司筹资factor△V1 【by: sc泡泡】还有一遍是说公司会把invoice 卖给特地收集什么的公司叫factor,然后说刚成立的公司常常用这种方法筹集钱,由于他们在银行借不到。

第三段就说这种方法对有些公司不适合,那些卖许多small invoice 就不适合。

V2 【by: zzfw0824】似乎有问找factor 有什么弊端。

还有就是Factor怎么来定位他们该受理什么样的公司似乎补充背景学问:amosfan(以下文字非机经,是与本篇狗狗相关的专业学问,供大家了解factor为何物)1.1.11 公司筹资。

这里的factor是国际贸易中的保理业务。

这个和我的工作有关,可以略微讲一下。

大致概念是:将国际贸易业务中的应收账款(AR)外包给第三方公司,代为催收(也就是把所invoice卖给第三方公司)。

对于出口企业来说,好处是:1.能够马上拿到cash,缩短账期(国际贸易中往往有些应收账款>90天)2.转移应收账款风险。

对于第三方公司来说,固然从中需要抽取一局部佣金的。

这种结款方式一般用在大型工程选购,或者目的地信用风险较高的国家比拟多用。

一般商品贸易中很少会用这种方式考古蒙小灰 selfay 已确认V1讲factor business的,大意就是说factor business为什么会存在,由于许多公司需要通过这些公司来躲避风险和来削减各种费用,比方说invoice转帐等,另外一些心公司也会通过这些factor business,由于最初好像他们很难向银行贷款,然后说由于他们将来会有进展前景,所以factor business也情愿贷款之类的,我就不说答案了吧,由于我真的觉得我错了,虽然我我当时很确定,不过我刚说的话里面都是有问题问的,比方说factor business为什么情愿贷款给新公司之类的。

V2 by小熊西西 (740)阅读有一篇是讲融资业务中的保付代理业务(factor)。

为了让我们更好(de)适应GMAT考试,GMAT考试官网每天都会有GMAT试题,下面是天道小编为您整理(de)2016年7月19日GMAT考试题目,是阅读题,让我们一起来看一看这道题目吧.A recent study has provided clues to predator-prey dynamics in the late Pleistocene era. Researchers compared the number of tooth fractures in present-day carnivores with tooth fractures in carnivores that lived 36,000 to 10,000 years ago and that were preserved in the Rancho La Brea tar pits in Los Angeles. The breakage frequencies in the extinct species were strikingly higher than those in the present-day species.In considering possible explanations for this finding, the researchers dismissed demographic bias because older individuals were not overrepresented in the fossil samples. They rejected preservational bias because a total absence of breakage in two extinct species demonstrated that the fractures were not the result of abrasion within the pits. They ruled out local bias because breakage data obtained from other Pleistocene sites were similar to the La Brea data. The explanation they consider most plausible is behavioral differences between extinct and present-day carnivores—in particular, more contact between the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct species.Such thorough carcass consumption implies to the researchers either that prey availability was low, at least seasonally, or that there was intense competition over kills and a high rate of carcass theft due to relatively high predator densities.1、The primary purpose of the passage is toA、present several explanations for a well-known factB、suggest alternative methods for resolving a debateC、argue in favor of a controversial theoryD、question the methodology used in a studyE、discuss the implications of a research finding正确答案 E2、According to the passage, compared with Pleistocene carnivores in other areas, Pleistocene carnivores in the La Brea areaA、included the same species, in approximately the same proportionsB、had a similar frequency of tooth fracturesC、populated the La Brea area more denselyD、consumed their prey more thoroughlyE、found it harder to obtain sufficient prey正确答案 B3、According to the passage, the researchers believe that the high frequency of tooth breakage in carnivores found at La Brea was caused primarily byA、the aging process in individual carnivoresB、contact between the fossils in the pitsC、poor preservation of the fossils after they were removed from the pitsD、the impact of carnivores’ teeth against the bones o f their preyE、the impact of carnivores’ teeth against the bones of other carnivores during fights over kills正确答案 D4、The researchers’ conclusion concerning the absence of demographic bias would be most seriously undermined if it were found thatA、the older an individual carnivore is, the more likely it is to have a large number of tooth fracturesB、the average age at death of a present-day carnivore is greater than was the average age at death of a Pleistocene carnivoreC、in Pleistocene carnivore species, older individuals consumed carcasses as thoroughly as did younger individualsD、the methods used to determine animals’ ages in fossil samples tend to misidentify many older individuals as younger individualsE、data concerning the ages of fossil samples cannot provide reliable information about behavioral differences between extinct carnivores and present-day carnivores 正确答案 D5、According to the passage, if the researchers had NOT found that two extinct carnivore species were free of tooth breakage, the researchers would have concluded thatA、the difference in breakage frequencies could have been the result of damage to the fossil remains in the La Brea pitsB、the fossils in other Pleistocene sites could have higher breakage frequencies than do the fossils in the La Brea pitsC、Pleistocene carnivore species probably behaved very similarly to one another with respect to consumption of carcassesD、all Pleistocene carnivore species differed behaviorally from present-day carnivore speciesE、predator densities during the Pleistocene era were extremely high正确答案 A6、The passage suggests that if the researchers had not found that two extinct carnivore species were free of tooth breakage, the researchers would have concluded thatA、the difference in breakage frequencies could have been the result of damage to the fossile remains in the La Brea pitsB、the fossils in other Pleistocene sites could have higher breakage frequencies than do the fossils in the La Brea pitsC、Pleistocene carnivore species probably behaved very similarly to one another with respect to consumption of carcassD、all Pleistocene carnivores species differed behaviorally from present-day carnivore species.E、predator desities during the Pleistocene era were extremely high正确答案 A7、The passage suggests that tooth fractures in Pleistocene carnivores probably tended to occur less frequentlyA、during periods in which more prey were availableB、at sites distant from the La Brea areaC、in older individual carnivoresD、in species that were not preserved as fossilsE、in species that regularly stole carcasses from other species正确答案 A以上就是天道小编为根据GMAT考试官网最新信息,为您整理(de)2016年7月19日GMAT 试题,目(de)是为了让我们更好(de)适应GMAT考试题目,如果在备考过程中遇到任何问题,欢迎随时咨询天道培训,为您提供最专业、最全面(de)解答.GMAT金牌一对一想要快速提分,一对一最适合你1一对一会根据你(de)实际情况制定计划2每天有专职顾问记录你全天(de)学习进度3授课(de)时间、地点、形式都非常灵活4一对一授课(de)吸收率是大班课(de)5倍5教学更具交流性,课堂上可随时反馈6每学科教师辅导+专门学习顾问+助教数据证明一对一授课(de)吸收率,是大班课(de)5倍天道标准化GMAT课程教学体系——平均教龄5年以上教师研发,历经多年GMAT考试实战验证,数据证明一对一授课(de)吸收率,一对一授课效率是小班授课(de)2~3倍,是大班课(de)5倍,最大限度保证学习效果,家长要做(de)就是放心把孩子交给天道.。

GMAT考试阅读试题(一)(4)

GMAT考试阅读试题(一)(4)

Passage 4 The fossil remains of the first flying vertebrates, the pterosaurs, have intrigued paleontologists for morethan two centuries. How such large creatures, which weighed in some cases as much as a piloted hang-glider(5) and had wingspans from 8 to 12 meters, solved theproblems of powered flight, and exactly what thesecreatures were——reptiles or birds-are among the ques-tions scientists have puzzled over. Perhaps the least controversial assertion about the(10) pterosaurs is that they were reptiles. Their skulls,pelvises,and hind feet are reptilian. The anatomy oftheir wings suggests that they did not evolve into theclass of birds. In pterosaurs a greatly elongated fourthfinger of each forelimb supported a winglike membrane.(15) The other fingers were short and reptilian, with sharpclaws. In birds the second finger is the principal strutof the wing, which consists primarily of feathers. If thepterosaurs walked on all fours, the three short fingersmay have been employed for grasping. When a(20) pterosaur walked or remained stationary, the fourthfinger, and with it the wing, could only turn upward inan extended inverted V-shape along each side of the animal‘s body. The pterosaurs resembled both birds and bats in(25) their overall structure and proportions. This is not sur-prising because the design of any flying vertebrate issubject to aerodynamic constraints. Both the pterosaursand the birds have hollow bones, a feature that repre-sents a savings in weight. In the birds, however, these(30) bones are reinforced more massively by internal struts. Although scales typically cover reptiles, thepterosaurs probably had hairy coats. T.H. Huxley rea-soned that flying vertebrates must have been warm-blooded because flying implies a high rate of(35) metabolism, which in turn implies a high internal tem-perature. Huxley speculated that a coat of hair wouldinsulate against loss of body heat and might streamlinethe body to reduce drag in flight. The recent discoveryof a pterosaur specimen covered in long, dense,and(40) relatively thick hairlike fossil material was the first clearevidence that his reasoning was correct. Efforts to explain how the pterosaurs became air-borne have led to suggestions that they launched them-selves by jumping from cliffs, by dropping from trees.(45) or even by rising into light winds from the crests ofwaves. Each hypothesis has its difficulties. The firstwrongly assumes that the pterosaurs‘ hind feet rese-mbled a bat’s and could serve as hooks by which theanimal could hang in preparation for flight. The second(50) hypothesis seems unlikely because large pterosaurscould not have landed in trees without damaging theirwings. The third calls for high waves to channelupdrafts. The wind that made such waves however,might have been too strong for the pterosaurs to(55) control their flight once airborne.1. It can be inferred from the passage that scientists now generally agree that the (A) enormous wingspan of the pterosaurs enabled them to fly great distances  (B) structure of the skeleton of the pterosaurs suggests a close evolutionary relationship to bats (C) fossil remains of the pterosaurs reveal how they solved the problem of powered flight (D) pterosaurs were reptiles (E) pterosaurs walked on all fours2. The author views the idea that the pterosaurs became airborne by rising into light winds created by waves as (A) revolutionary (B) unlikely (C) unassailable (D) probable (E) outdated3. According to the passage, the skeleton of a pterosaur can be distinguished from that of a bird by the (A) size of its wingspan (B) presence of hollow spaces in its bones (C) anatomic origin of its wing strut (D) presence of hooklike projections on its hind feet (E) location of the shoulder joint joining the wing to its body4. The ideas attributed to T.H. Huxley in the passage suggest that he would most likely agree with which of the following statements? (A) An animal‘s brain size has little bearing on its ability to master complex behaviors. (B) An animal‘s appearance is often influenced by environmental requirements and physical capabilities. (C) Animals within a given family group are unlikely to change their appearance dramatically over a period of time. (D) The origin of flight in vertebrates was an accidental development rather than the outcome of specialization or adaptation. (E) The pterosaurs should be classified as birds, not reptiles.5. It can be inferred from the passage that which of the following is characteristic of the pterosaurs? (A) They were unable to fold their wings when not in use. (B) They hung upside down from branches as bats do before flight. (C) They flew in order to capture prey.  (D) They were an early stage in the evolution of the birds. (E) They lived primarily in a forestlike habitat.6.Which of the following best describes the organization of the last paragraph of the passage? (A) New evidence is introduced to support a traditional point of view. (B) Three explanations for a phenomenon are presented, and each is disputed by means of specific information. (C) Three hypotheses are outlined, and evidence supporting each is given. (D) Recent discoveries are described, and their implications for future study are projected (E) A summary of the material in the preceding paragraphs is presented, and conclusions are drawn.7. It can be inferred from the passage that some scientists believe that pterosaurs (A) lived near large bodies of water (B) had sharp teeth for tearing food (C) were attacked and eaten by larger reptiles (D) had longer tails than many birds  (E) consumed twice their weight daily to maintain their body temperature。

文章练习Passage IOf all modern instruments, the violin is apparently one of the simplest. It consists inessence of a hollow, varnished wooden sound box, or resonator, and a long neck, covered with a fingerboard, along which four strings are stretched at high tension. The beauty of Line design, shape, and decoration is no accident: the proportions of the instrument are (5) determined almost entirely by acoustical considerations. Its simplicity of appearance isdeceptive. About 70 parts are involved in the construction of a violin, Its tone and itsoutstanding range of expressiveness make it an ideal solo instrument. No less important.however, is its role as an orchestral and chamber instrument. In combination with the larger and deeper-sounding members of the same family, the violins form the nucleus (10) of the modern symphony orchestra.The violin has been in existence since about 1550. Its importance as an instrumentin its own right dates from the early 1600's, when it first became standard in Italianopera orchestras. Its stature as an orchestral instrument was raised further when in 1626 Louis XIII of France established at his court the orchestra known as Les vingt-quatre (15) violons du Roy (The King's 24 Violins), which was to become widely famous later inthe century.In its early history, the violin had a dull and rather quiet tone resulting from the factthat the strings were thick and were attached to the body of the instrument very loosely.During the eighteenth and nineteenth century, exciting technical changes were inspired (20) by such composer-violinists as Vivaldi and Tartini. Their instrumental compositionsdemanded a fuller, clearer, and more brilliant tone that was produced by using thinner strings and a far higher string tension. Small changes had to be made to the violin'sinternal structure and to the fingerboard so that they could withstand the extra strain.Accordingly, ,a higher standard of performance was achieved, in terms of both facility (25) and interpretation. Left-hand technique was considerably elaborated, and new fingeringpatterns on the fingerboard were developed for very high notes.1. The word "standard" in line 12 is closest in meaning to2. "The King’s 24 Violins" is mentioned in line 15 to illustrate3. What is the main idea presented in paragraph 3?4. The author mentions Vivaldi and Tartini in line 20 as examples of composers whose music5. The word "they" in line 23 refers to6. The word "strain" in line 23 is closest in meaning to7. The word "Accordingly" in line 24 is closest in meaning to8. According to the passage, early violins were different from modern violins in that early violins9. According to the passage, which of the following contributes to a dull sound being produced by a violin?10. All of the following are mentioned in the passage as contributing to the ability to play modern violin music EXCEPTPassage IIQuestion 41-50Naturalists and casual observers alike have been struck by the special relationshipbetween squirrels and acorns (the seeds of oak trees). Ecologists, though, cannot observe These energetic mammals scurrying up and down oak trees and eating and burying acorns without wondering about their complex relationship with trees. Are squirrels dispersers (5) and planters of oak forests or pesky seed predators? The answer is not simple. Squirrelsmay devour many acorns, but by storing and failing to recover up to 74 percent of them(as they do when seeds are abundant), these arboreal o\rodents can also aid regeneration and dispersal of the oaks.Their destructive powers are well documented. According to one report, squirrels(10)destroyed tens of thousands of fallen acorns from an oak stand on the University ofIndiana campus. A professor there estimated that each of the large while oaks hadProduced between two and eight thousand acorns, but within weeks of seed maturity,Hardly an intact acorn could be found among the fallen leaves.Deer, turkey, wild pigs, and bears also feed heavily on acorns, but do not store them, (15)And are therefore of no benefit to the trees. Flying squirrels, chipmunks, and mice areAlso unlikely to promote tree dispersal--- whose behavior of caching (hiding) acorns below The leaf litter often promotes successful germination of acorns --- and perhaps blue jays, Important long-distance dispersers, seem to help oaks spread and reproduce.Among squirrels, though, there is a particularly puzzling behavior pattern. Squirrels (20)pry off the caps of acorns, bite through the shells to get at the nutritious inner kernels,and then discard them half-eaten. The ground under towing oaks is often littered withthousands of half -eaten acorns, each one only bitten from the top. Why would any animal waste so much time and energy and risk exposure to such predators as red-tail hawks only to leave a large part of each acorn uneaten? While research is not conclusive at this point, (25)one thing that is certain is that squirrels do hide some of the uneaten portions, and theseacorn halves, many of which contain the seeds, may later germinate.41. What does the passage mainly discuss?42. The word "they" in line 7 refers to43. According to the passage, what do squirrels do when large quantities of acorns are available?44. The word "estimated" in line 11 is closest in meaning to45. Why does the author mention “the University of Indiana campus" in line 10-1146. It can be inferred from paragraph 3 that chipmunks do not aid in the dispersal of oak trees because47. According to the passage, which of the following do squirrels and blue jays have in common?48. The phrase “pry off" in line 21 is closest in meaning to49. The word "littered" in line 22 is closest in meaning to50. According to the passage, scientists cannot explain which of the following aspects of squirrel behavior?Passage IIIGovernments of developing countries occasionally enter into economic development agreements with foreign investors who provide capital and technological expertise that may not be readily available in such countries. Besides the normal economic risk that accompanies such enterprises, investors face the additional risk that the host government may attempt unilaterally to change in its favor the terms of the agreement or even to terminate the agreement altogether and appropriate the project for itself. In order to make economic development agreements more attractive to investors, some developing countries have attempted to strengthen the security of such agreements with clauses specifying that the agreements will be governed by “general principles of law recognized by civilized nations”—a set of legal principles or rules shared by the world’s major legal systems. However, advocates of governments’ freedom to modify or terminate such agreements argue that these agreements fall within a special class of contracts known as administrative contracts, a concept that originated in French law. They assert that under the theory of administrative contracts, a government retains inherent power to modify or terminate its own contract, and that this power indeed constitutes a general principle of law. However, their argument is flawed on at least two counts.First, in French law not all government contracts are treated as administrative contracts. Some contracts are designated as administrative by specific statute, in which case the contractor is made aware of the applicable legal rules upon entering into agreement with the government. Alternatively, the contracting government agency can itself designate a contract as administrative by including certain terms not found in private civil contracts. Moreover, even in the case of administrative contracts, French law requires that in the event that the government unilaterally modifies the terms of the contract, it must compensate the contractor for any increased burden resulting from the government’s action. In effect, the government is thus prevented from modifying those contractual terms that define the financial balance of the contract.Second, the French law of administrative contracts, although adopted by several countries, is not so universally accepted that it can be embraced as a general principle of law. In both the United States and the United Kingdom, government contracts are governed by the ordinary law of contracts, with the result that the government can reserve the power to modify or terminatea contract unilaterally only by writing such power into the contract as a specific provision. Indeed, the very fact that termination and modification clauses are commonly found in government cont racts suggests that a government’s capacity to modify or terminate agreements unilaterally derives from specific contract provisions, not from inherent state power.。

Passage 29 Studies of the Weddell seal in the laboratory have described the physiological mechanisms that allow the seal to cope with the extreme oxygen deprivation that occurs during its longest dives, which can extend 500(5) meters below the ocean‘s surface and last for over 70 minutes. Recent field studies, however, suggest that during more typical dives in the wild, this seal’s physio-logical behavior is different. In the laboratory, when the seal dives below the(10) surface of the water and stops breathing, its heart beats more slowly, requiring less oxygen, and its arteries become constricted, ensuring that the seal‘s blood remains concentrated near those organs most crucial to its ability to navigate underwater. The seal essentially(15) shuts off the flow of blood to other organs, which either stop functioning until the seal surfaces or switch to an anaerobic (oxygen-independent) metabolism. The latter results in the production of large amounts of lactic acidwhich can adversely affect the pH of the seal’s blood(20) but since the anaerobic metabolism occurs only in those tissues which have been isolated from the seal‘s blood supply, the lactic acid is released into the seal’s blood only after the seal surfaces, when the lungs,liver, and other organs quickly clear the acid from the seal‘s blood-(25) stream. Recent field studies, however, reveal that on dives in the wild, the seal usually heads directly for its prey and returns to the surface in less than twenty minutes. The absence of high levels of lactic acid in the seal‘s blood(30) after such dives suggests that during them, the seal’s organs do not resort to the anaerobic metabolism observed in the laboratory, but are supplied with oxygen from the blood. The seal‘s longer excursions underwater,during which it appears to be either exploring distant(35) routes or evading a predator, do evoke the diving response seen in the laboratory. But why do the seal’s laboratory dives always evoke this response, regardless of their length or depth?Some biologists speculate that because in laboratory dives the seal is forcibly(40) submerged, it does not know how long it will remain underwater and so prepares for the worst. 1. The passage provides information to support which of the following generalizations? (A) Observations of animals‘ physiological behavior in the wild are not reliable unless verified by laboratory studies. (B) It is generally less difficult to observe the physiological behavior of an animal in the wild than in the laboratory. (C) The level of lactic acid in an animal‘s blood is likelyto be higher when it is searching for prey than whenit s evading predators. (D) The level of lactic acid in an animal‘s blood is likely to be lowest during those periods in which it experiences oxygen deprivation. (E) The physiological behavior of animals in a laboratory setting is not always consistent with their physiological behavior in the wild. 2. It can be inferred from the passage that by describing the Weddell seal as preparing “for the worst” (line 41),biologists mean that it (A) prepares to remain underwater for no longer than twenty minutes (B) exhibits physiological behavior similar to that which characterizes dives in which it heads directly for its prey (C) exhibits physiological behavior similar to that which characterizes its longest dives in the wild. (D) begins to exhibit predatory behavior (E) clears the lactic acid from its blood before attempting to dive 3. The passage suggests that during laboratory dives, the pH of the Weddell seal‘s blood is not adversely affected by the production of lactic acid because (A) only those organs that are essential to the seal‘s ability to navigate underwater revert to an anaerobic mechanism. (B) the seal typically reverts to an anaerobic metabolism only at the very end of the dive (C) organs that revert to an anaerobic metabolism aretemporarily isolated from the seal‘s bloodstream (D) oxygen continues to be supplied to organs that clear lactic acid from the seal‘s bloodstream (E) the seal remains submerged for only short periods of time 4. Which of the following best summarizes the main point of the passage? (A) Recent field studies have indicated that descriptions of the physiological behavior of the Weddell sealduring laboratory dives are not applicable to its mosttypical dives in the wild. (B) The Weddell seal has developed a number of unique mechanisms that enable it to remain submerged at depths of up to 500 meters for up to 70 minutes. (C) The results of recent field studies have made it necessary for biologists to revise previousperceptions of how the Weddell seal behavesphysiologically during its longest dives in the wild. (D) Biologists speculate that laboratory studies of the physiological behavior of seals during dives lastingmore than twenty minutes would be more accurate ifthe seals were not forcibly submerged. (E) How the Weddell seal responds to oxygen deprivation during its longest dives appears to depend on whether the seal is searching for prey or avoiding predators during such dives. 5. According to the author, which of the following is true of the laboratory studies mentioned in line 1 ? (A) They fail to explain how the seal is able to tolerate the increased production of lactic acid by organs that revert to an anaerobic metabolism during its longest dives in the wild. (B) They present an oversimplified account of mechanisms that the Weddell seal relies on during its longest dives in the wild. (C) They provide evidence that undermines the view that the Weddell seal relies on an anaerobic metabolism during its most typical dives in the wild. (D) They are based on the assumption that Weddell seals rarely spend more than twenty minutes underwater on a typical dive in the wild. (E) They provide an accurate account of the physiological behavior of Weddell seals during those dives in the wild in which they are either evading predators or exploring distant routes. 6. The author cites which of the following as characteristic of the Weddell seal‘s physiological behavior during dives observed in the laboratory? Ⅰ. A decrease in the rate at which the seal‘s heart beats Ⅱ. A constriction of the seal‘s arteries Ⅲ. A decrease in the levels of lactic acid in the seal‘s blood  Ⅳ. A temporary halt in the functioning of certain organs (A)Ⅰand Ⅲ only (B)Ⅱ and Ⅳ only (C)Ⅱ and Ⅲ only (D)Ⅰ,Ⅱ, and Ⅳ only (E)Ⅰ,Ⅲ, and Ⅳ only 7. The passage suggests that because Weddell seals are forcibly submerged during laboratory dives, they do which of the following? (A) Exhibit the physiological responses that are characteristic of dives in the wild that last less than twenty minutes. (B) Exhibit the physiological responses that are characteristic of the longer dives they undertake in the wild. (C) Cope with oxygen deprivation less effectively than they do on typical dives in the wild. (D) Produce smaller amounts of lactic acid than they do on typical dives in the wild. (E) Navigate less effectively than they do on typical dives in the wild。

Few academic programs have ever received such public attention. In broadcast debates, critics dismissed the program as a betrayal of national identity, an imitation of Western ideas, and a distraction from the real task of national unification and economic development. Even supporters underestimated the program; they thought it would be merely another of the many Western ideas that had already proved useful in Asian culture, akin to airlines, electricity, and the assembly line. The founders of the program, however, realized that neither view was correct. They had some reservations about the applicability of Western feminist theories to the role of women in Asia and felt that such theories should be closely examined. Their approach has thus far (thus far: 迄今) yielded important critiques of Western theory, informed by the special experience of Asian women.For instance, like the Western feminist critique of the Freudian model of the human psyche, the Korean critique findsFreudian theory culture-bound, but in ways different from those cited by Western theorists. The Korean theorists claim that Freudian theory assumes the universality of the Western nuclear, male-headed family and focuses on the personality formation of the individual, independent of , family members are assumed to be engaged in a Darwinian struggle against each other—father against son and sibling against sibling. Such a concept projects the petitive model of Western society onto human personalities. But in the Asian concept of personality there is no ideal attached to individualism or to the independent self. The Western model of personality development does not explain major characteristics of the Korean personality, which is social and group-centered. The “self” is a social being defined by and acting in a group, and the well-being of both men and women is determined by the equilibrium of the group, not by individual self-assertion (1: the act of asserting oneself or one's own rights, claims, or opinions 2: the act of asserting one's superiority over others). The ideal is one of interdependency.In such a context, what is recognized as “dependency” in Western psychiatric terms is not, in Korean terms, an admission of weakness or failure. All this bears directly on the Asianperception of men’s and women’s psychology because men are also “dependent.” In Korean culture, men cry and otherwise easily show their emotions, something that might be considered a betrayal of masculinity in Western culture. In the kinship-based society of Korea, four generations may live in the same house, which means that people can be sons and daughters all their lives, whereas in Western culture, the roles of husband and son, wife and daughter, are often patible.1. Which of the following best summarizes the content of the passage?(A) A critique of a particular women’s studies program(B) A report of work in social theory done by a particular women’s studies program(C) An assessment of the strengths and weaknesses of a particular women’s studies program(D) An __ysis of the philosophy underlying women’s studies programs(B)(E) An abbreviated history of Korean w omen’s studies programs2. It can be inferred from the passage that Korean scholars in the field of women’s studies undertook an __ysis of Freudiantheory as a response to which of the following?(A) Attacks by critics of the Ewha women’s studies progr am(B) The superficiality of earlier critiques of Freudian theory(C) The popularity of Freud in Korean psychiatric circles(D) Their desire to encourage Korean scholars to adopt the Freudian model(E)(E) Their assessment of the relevance and limitations of Western feminist theory with respect to Korean culture3. Which of the following conclusions about the introduction of Western ideas to Korean society can be supported by information contained in the passage?(A) Except for technological innovations, few Western ideas have been successfully transplanted into Korean society.(B) The introduction of Western ideas to Korean society is viewed by some Koreans as a challenge to Korean identity.(C) The development of the Korean economy depends heavily on the development of new academic programs modeled after Western programs.(D) The extent to which Western ideas must be adapted for acceptance by Korean society is minimal.(B)(E) The introduction of Western ideas to Korean societyaccelerated after 1977.4. It can be inferred from the passage that the broadcast media in Korea considered the establishment of the Ewha women’s studies program(A) praiseworthy(B) insignificant(C) newsworthy(D) imitative(C)(E) prehensible5. It can be inferred from the passage that the position taken by some of the supporters of the Ewha women’s studies program was problematic to the founders of the program because those supporters(A) assumed that the program would be based on the uncritical adoption of Western theory(B) failed to show concern for the issues of national unification and economic development(C) were unfamiliar with Western feminist theory(D) were not themselves scholars in the field of women’s studies(A)(E) accepted the universality of Freudian theory6. Which of the following statements is most consistent with the view of personality development held by the Ewha women’s studies group?(A) Personality development occurs in identifiable stages, beginning with dependency in childhood and ending with independence in adulthood.(B) Any theory of personality development, in order to be valid, must be universal.(C) Personality development is influenced by the characteristics of the society in which a person lives.(D) Personality development is hindered if a person is not permitted to be independent.(C)(E) No theory of personality development can account for the differences between Korean and Western culture.7. Which of the following statements about the Western feminist critique of Freudian theory can be supported by information contained in the passage?(A) It recognizes the influence of Western culture on Freudian theory.(B) It was written after 1977.(C) It acknowledges the universality of the nuclear, male-headed family.(D) It challenges Freud’s __ysis of the role of daughters in Western society.(A)(E) It fails to address the issue of petitiveness in Western society.8.

Although genetic mutations in bacteria and viruses can lead to epidemics, some epidemics are caused by bacteria and viruses that have undergone no significant genetic change. In analyzing the latter, scientists have discovered the importance of social and ecological factors to epidemics. Poliomyelitis (poliomyelitis: n.小儿麻痹症, 急性骨髓灰白质炎), for example, emerged as an epidemic in the United States in the twentieth century; by then (by then: 到那时候), modern sanitation was able to delay exposure to polio (POLIOMYELITIS) until adolescence or adulthood, at which time polio infection produced paralysis. Previously, infection had occurred during infancy, when it typically provided lifelong immunity without paralysis. Thus, the hygiene that helped prevent typhoid epidemics indirectly fostered a paralytic polio epidemic. Another example is Lyme disease, which is caused by bacteria that are transmitted by deerticks. It occurred only sporadically during the late nineteenth century but has recently become prevalent in parts of the United States, largely due to an increase in the deer population that occurred simultaneously with the growth of the suburbs and increased outdoor recreational activities in the deer’s habitat. Similarly, an outbreak of dengue hemorrhagic fever became an epidemic in Asia in the 1950’s because of ecological changes that caused Aedes aegypti, the mosquito that transmits the dengue virus, to proliferate. The stage is now set in the United States for a dengue epidemic because of the inadvertent introduction and wide dissemination of another mosquito, Aedes albopictus.

GMAT阅读模拟试题及答案解析

GMAT 阅读模拟试题及答案解析Biologists have advanced two theories to explain why schooling of fish occurs in so many fish species. Because schooling is particularly wide spread among species of small fish, both theories assume that schooling offers the advantage of some protection from predators.Proponents of theory A dispute the assumption that a school of thousands of fish is highly visible. Experiments have shown that any fish can be seen, even in very clear water, only within a sphere of 200 meters in diameter. When fish are in a compact group, the sphere of visibility overlap. Thus, the chance of a predator finding the school is only slightly greater than the chance of the predator finding a single fish swimming alone. Schooling is advantageous to the individual fish because a predator’s chance of finding any particular fish swimming in the school is much smaller than its chance of finding at least one of the same group of fish if the fish were dispersed throughout an area.However, critics of theory A point out that some fish form schools even in areas where predators are abundant and thus little possibility fo excaping detection exists. They argue that the school continues to be of value to its members even after detection. They advocate theory B, the “confusion effect,” which can be explained in two different ways.Sometimes, proponents argue, predators simply cannot decide which fish to attack. This indecision supposedly results from a predator’s preference for striking prey that is distinct from the rest of the school in appearance. In many schools the fish are almost indentical in appearance, making it difficult for a predator to select one. The second explanation for the。

Recent years have brought minority-owned businesses in the United States unprecedented opportunities—as well as new and significant risks. Civil rights activists have long argued that one of the principal reasons why 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. Now Congress, in apparent agreement, has required by law that businesses awarded federal contracts of more than $500,000 do their best to find minority subcontractors and record their efforts to do so on forms filed with the government. Indeed, some federal and local agencies have gone so far as to set specific percentage goals for apportioning parts of public works contracts to minority enterprises.Corporate response appears to have been substantial. According to figures collected in 1977, the total of corporate contracts with minority businesses rose from $77 million in 1972 to $1.1 billion in 1977. The projected total of corporate contracts with minority businesses for the early 1980’s is estimated to be over 53 billion per year with no letup anticipated in the next decade. Promising as it is for minority businesses, this increased patronage poses dangers for them, too. First, minority firms risk expanding too fast and overextending themselves financially, since most are small concerns and, unlike large businesses, they often need to make substantial investments in new plants, staff, equipment, and the like in order to perform work subcontracted to them. If, thereafter, their subcontracts are for some reason reduced, such firms can face potentially crippling fixed expenses. The world of corporate purchasing can be frustrating for small entrepreneurs who get requests for elaborate formal estimates and bids. Both consume valuable time and resources, and a small company’s efforts must soon result in orders, or both the morale and the financial health of the business will suffer.A second risk is that White-owned companies may seek to cash in on the increasing apportionments through formation of joint ventures with minority-owned concerns. Of course, in many instances there are legitimate reasons for joint ventures; clearly, White and minority enterprises can team up (team up: v.(使)结成一队, 合作, 协作) to acquire business that neither could acquire alone. But civil rights groups and minority business owners have complained to Congress about minoritiesbeing set up as “fronts (a person, group, or thing use d to mask the identity or true character or activity of the actual controlling agent)” with White backing, rather than being accepted as full partners in legitimate joint ventures.Third, a minority enterprise that secures the business of one large corporate customer often runs the danger of becoming—and remaining—dependent. Even in the best of circumstances, fierce competition from larger, more established companies makes it difficult for small concerns to broaden their customer bases: when such firms have nearly guaranteed orders from a single corporate benefactor, they may truly have to struggle against complacency arising from their current success.1. The primary purpose of the passage is to(A) present a commonplace idea and its inaccuracies(B) describe a situation and its potential drawbacks(C) propose a temporary solution to a problem(D) analyze a frequent source of disagreement(E) explore the implications of a finding2. The passage supplies information that would answer which of the following questions?(A) What federal agencies have set percentage goals for the use of minority-owned businesses in public works contracts?(B) To which government agencies must businesses awarded federal contracts report their efforts to find minority subcontractors?(C) How widespread is the use of minority-owned concerns as “fronts” by White backers seeking to obtain subcontracts?(D) How many more minority-owned businesses were there in 1977 than in 1972?(E) What is one set of conditions under which a small business might find itself financially overextended?3. According to the passage, civil rights activists maintain that one disadvantage under which minority-owned businesses have traditionallyhad to labor (to suffer fro m some disadvantage or distress “labor under a delusion”) is that they have(A) been especially vulnerable to governmental mismanagement of the economy(B) been denied bank loans at rates comparable to those afforded larger competitors(C) not had sufficient opportunity to secure business created by large corporations(D) not been able to advertise in those media that reach large numbers of potential customers(E) not had adequate representation in the centers of government power4. The passage suggests that the failure of a large business to have its bids for subcontracts result quickly in orders might cause it to(A) experience frustration but not serious financial harm(B) face potentially crippling fixed expenses(C) have to record its efforts on forms filed with the government(D) increase its spending with minority subcontractors(E) revise its procedure for making bids for federal contracts and subcontracts5. The author implies that a minority-owned concern that does the greater part of its business with one large corporate customer should(A) avoid competition with larger, more established concerns by not expanding(B) concentrate on securing even more business from that corporation(C) try to expand its customer base to avoid becoming dependent on the corporation(D) pass on some of the work to be done for the corporation to other minority-owned concerns(E) use its influence with the corporation to promote subcontracting with other minority concerns6. It can be inferred from the passage that, compared with the requirements of law, the percentage goals set by “some federal and local agencies” (lines 14-15) are(A) more popular with large corporations(B) more specific(C) less controversial(D) less expensive to enforce(E) easier to comply with7. Which of the following, if true, would most weaken the author’s assertion that, in the 1970’s, corporate response to federal requirements (lines 18-19) was substantial(A) Corporate contracts with minority-owned businesses totaled $2 billion in 1979.(B) Between 1970 and 1972, corporate contracts with minority-owned businesses declined by 25 percent.(C) The figures collected in 1977 underrepresented the extent of corporate contracts with minority-owned businesses.(D) The estimate of corporate spending with minority-owned businesses in 1980 is approximately $10 million too high.(E) The $1.1 billion represented the same percentage of total corporate spending in 1977 as did $77 million in 1972.8. The author would most likely agree with which of the following statements about corporate response to working with minority subcontractors?(A) Annoyed by the proliferation of “front” organizations, corporations are likely to reduce their efforts to work withminority-owned subcontractors in the near future.(B) Although corporations showed considerable interest in working with minority businesses in the 1970’s, their aversion to government paperwork made them reluctant to pursue many government contracts.(C) The significant response of corporations in the 1970’s is likely to be sustained and conceivably be increased throughout the 1980’s.(D) Although corporations are eager to cooperate with minority-owned businesses, a shortage of capital in the 1970’s made substantial response impossible.(E) The enormous corporate response has all but eliminated the dangers of over-expansion that used to plague small minority-owned businesses.参考答案:BECA CBEC。
