Passage One

Questions 1-7 are based on the following passage:

According to a recent theory, Archean-age gold-quartz vein systems were formed over two billion years ago from magmatic fluids that originated from molten granitelike bodies deep beneath the surface of the Earth. This theory is contrary to the widely held view that the systems were deposited from metamorphic fluids, that is, from fluids that formed during the dehydration of wet sedimentary rocks. The recently developed theory has considerable practical importance. Most of the gold deposits discovered during the original gold rushes were exposed at the Earth’s surface and were found because the y had shed trails of alluvial gold that were easily traced by simple prospecting methods. Although these same methods still leas to an occasional discovery, most deposits not yet discovered have gone undetected because they are buried and have no surface expression.

The challenge in exploration is therefore to unravel the subsurface geology of an area and pinpoint the position of buried minerals. Methods widely used today include analysis of aerial images that yield a broad geological overview, geophysical techniques that provide data on the magnetic, electrical, and mineralogical properties of the rocks being investigated, and sensitive chemical tests that are able to detect : the subtle chemical halos that often envelop mineralization. However, none of these high-technology methods are of any value if the sites to which they are applied have never mineralized, and to maximize the chances of discovery the explorer must therefore pay particular attention to selecting the ground formations most likely to be mineralized. Such ground selection relies to varying degrees on conceptual models, which take into account theoretical studies of relevant factors.

These models are constructed primarily from empirical observations of known mineral deposits and from theories of ore-forming processes. The explorer uses the models to identify those geological features that are critical to the formation of the mineralization being modeled, and then tries to select areas for exploration that exhibit as many of the critical features as possible.

A. advocating a return to an older methodology.

B. explaining the importance of a recent theory.

C. enumerating differences between two widely used methods

D. describing events leading to a discovery

2. According to passage, the widely held view of Archean-age gold-quartz vein

systems is that such systems

years ago.

B Limiting exploration to sites known to have been formed form metamorphic

fluid.

C Using an appropriate conceptual model to select a site for further exploration.

D Using geophysical methods to analyze rocks over a broad area.

4. Which of the following statements about discoveries of gold

deposits is supported by information in the passage?

A The number of gold discover made annually has increased between the time of

the original gold rushes and the present

B New discoveries of gold deposits are likely to be the result of exploration

techniques designed to locate buried mineralization

C It is unlikely that newly discovered gold deposits will ever yield as much as did

those deposits discovered during the original gold rushes.

D Modern explorers are divided on the question of the utility of simple

prospecting methods as a source of new discoveries of gold deposits.

A A gold-quartz vein system originating in magma tic fluids.

B A gold-quartz vein system originating in metamorphic fluids.

C A gold deposit that is mixed with granite.

D A gold deposit that has shed alluvial gold.

6. The theory mentioned in line I relates to the conceptual models discussed in the

passage in which of the following ways?

A It may furnish a valid account of ore-forming processes, and hence, can

support conceptual models that have great practical significance.

B It suggests that certain geological formations, long believed to be mineralized,

are in fact mineralized thus confirming current conceptual models.

C. It suggests that there may not be enough similarity across Archean-age

gold-quartz vein systems to warrant the formulation of conceptual models.

D It corrects existing theories about the chemical halos of gold deposits, and

thus provides a basis for correcting current conceptual models.

7. According to the passage methods of exploring for gold that are widely used

today are based on which of the following facts?

A Most of the Earth’s remaining gold deposits are still molten.

B Most of the Earth’s remaining gold deposits are exposed at the surface.

C Most of the Earth’s remaining gold deposits are buried and have no surface

expression

D Only one type of gold deposit warrants exploration. since the other types of

gold deposits are found in regions difficult to reach

Passage Two

Questions 8-15 are based on the following passage:

In choosing a method for determining climatic conditions that existed in the past, paleoclimatologists invoke four principal criteria. First, the material—rocks, lakes, vegetation, etc.—on which the method relies must be widespread enough to provide plenty of information, since analysis of material that is rarely encountered will not permit correlation with other regions or with other periods of geological history. Second in the process of formation, the material must have received an environmental signal that reflects a change in climate and that can be deciphered by modern physical or chemical means. Third, at least some of the material must have retained the signal unaffected by subsequent changes in the environment. Fourth, it must be possible to determine the time at which the inferred climatic conditions held. This last criterion is more easily met in dating marine sediments, because dating of only a small number of layers in a marine sequence allows the age of other layers to be estimated fairly reliably by extrapolation and interpolation. By contrast, because sedimentation is much less continuous in continental regions, estimating the age of a continental bed from the known ages of beds above and below is more risky.

One very old method used in the investigation of past climatic conditions involves the measurement of water levels in ancient lakes. In temperate regions, there are enough lakes for correlations between them to give us a tenable picture. In arid and semiarid regions, on the other hand, the small number of lakes and the great distances between them reduce the possibilities for correlation. Moreover, since lake levels are controlled by rates of evaporation as well as by precipitation, the interpretation of such levels is ambiguous. For instance, the fact that lake levels in the semiarid southwestern United States appear to have been higher during the last ice age than they are now was at one time attributed to increased precipitation. On the basis of snowline elevations, however, it has been concluded that the climate then was not necessarily wetter than it is now, but rather that both summers and winters were cooler, resulting in reduced evaporation Another problematic method is to reconstruct former climates on the basis of pollen profiles. The type of vegetation in a specific region is determined by identifying and counting the various pollen grains found there. Although the relationship between vegetation and climate is not as direct as the relationship between climate and lake levels, the method often works well in the temperate zones. In arid and semiarid regions in which there is not much vegetation, however, small changes in one or a few plant types can change the picture traumatically, making accurate correlations between neighboring areas difficult to obtain.

8. Which of the following statements about the difference between marine

andcontinental sedimentation is supportedby information in the passage?

A.Data provided by dating marine sedimentation is more consistent with

researchers’ findings in other disciplines than is data provided by dating

continental sedimentation.

B.It is easier to estimate the age of a layer in a sequence of continental

10. It can be inferred from the passage that paleoclimatologists have concluded

which of the following on the basis of their study of snow-line elevations in the southwest6ern United States?

A.There is usually more precipitation during an ice age because of increased

amounts of evaporation

B.There was less precipitation during the last ice age than there is today.

https://www.sodocs.net/doc/1b17591086.html,ke levels in the semiarid southwestern United States were lower during the

last ice age than they are today.

D.The high lake levels during the last ice age may have been a result of less

evapo9ration rather than more precipitation.

11. Which of the following would be the most likely topic for a paragraph that logically

continues the passage?

A.The kinds of plants normally found in arid regions.

B.The effect of variation in lake levels on pollen distribution.

C.The material best suited to preserving signal of climatic changes.

D. A third method fro investigating past climatic conditions.

12. the author discusses lake levels in the southwestern United States in order to

C.Prove that there are not enough ancient lakes with which to make accurate

correlations

D.Explain the effects of increased rates of evaporation on levels of precipitation.

13. It can be inferred from the passage that an environmental signal found in

geological material would no be useful to paleoclimatologists if it .

A.had to be interpreted by modern chemical means

B.reflected a change in climate rather than a long-term climatic condition

C.was incorporated into a material as the material was forming

D.also reflected subsequent environmental changes.

14. According to the passage the material used to determine past climatic conditions

must be widespread for which of the following reasons?

Ⅰ.Paleoclimatologists need to make comparisons between periods of geological history. Ⅱ. Paleoclimatologists need to compare materials that have supported a wide variety of vegetation

Ⅲ. Paleoclimatologists need to make comparisons with data collected in other regions.

A.I only

B.Ⅱonly

C.I and Ⅱonly

D.I and Ⅲonly

15. Which of the following can be inferred from the passage about the study of past

climates in arid and semiarid regions?

A.It is sometimes more difficult to determine past climatic conditions in arid and

semiarid regions than in temperate regions

B.Although in the past more research has been done on temperate regions,

paleoclimatologists have recently turned their attention to arid and semiarid

regions.

C.Although more information about past climates can be gathered in arid and

semiarid than in temperate regions, dating this information is more difficult.

D.It is difficult to study the climatic history of arid and semiarid regions because

their climates have tended to vary more than those of temperate regions.

Passage Three

Questions 16-22 are based on the following passage:

While there is no blueprint for transforming a largely government-controlled economy into a free one, the experience of the United Kingdom since 1979 clearly shows one approach that works: privatization, in which state-owned industries are sold to private companies. By 1979, the total borrowings and losses of state-owned industries were running at about ￡3 billion a year. By selling many of these industries, the government has decreased these borrowings and losses, gained over ￡34 billion from the sales, and now receives tax revenues from the newly privatized companies. Along with a dramatically improved overall economy, the government has been able to repay 12.5 percent of the net national debt over a two-year period.

In fact privatization has not only rescued individual industries and a whole economy headed for disaster, but has also raised the level of performance in every area. At British Airways and British Gas, for example, productivity per employee has risen by 20 percent. At associated British Ports. labor disruptions common in the 1970’s and early 1980’s have now virtually disappeared. At British Telecom, there is no longer a

waiting list—as there always was before privatization—to have a telephone installed.

Part of this improved productivity has come about because the employees of privatized industries were given the opportunity to buy shares in their own companies. They responded enthusiastically to the offer of shares; at British Aerospace 89 percent of the eligible work force bought shares; at Associated British Ports 90 percent; and at British Telecom 92 percent. When people have a personal stake in something, they think about it, care about it, work to make it prosper. At the National Freight Consortium, the new employee-owners grew so concerned about their company’s profits that during wage negotiations they actually pressed their union to lower its wage demands. Some economists have suggested that giving away free shares would provide a needed acceleration of the privatization process. Yet they miss Thomas Paine’s point that ―what we obtain too cheap we esteem too lightly‖ In order for the far-ranging benefits of individual ownership to be achieved by owners, companies, and countries, employees and other individuals must make their own decisions to buy, and they must commit some of their own resources to the choice.

16. According to the passage all of the following were benefits of privatizing state

owned industries in the United Kingdom EXCEPT

A.Privatized industries paid taxes to the government

B.The government gained revenue from selling state-owned industries

C.The government repaid some of its national debt

D.Profits from industries that were still state-owned increased

17. According to the passage, which of the following resulted in increased productivity

in companies that have been privatized?

A. A large number of employees chose to purchase shares in their companies.

B.Free shares were widely distributed to individual shareholders.

C.The government ceased to regulate major industries.

D.Unions conducted wage negotiations fro employees.

18. It can be inferred from the passage that the author considers labor disruptions to be

A.an inevitable problem in a weak national economy

B. a positive sign of employee concern about a company

C. a predictor of employee reactions to a company’s offer to sell shares to them

D. a deterrence to high performance levels in an industry.

19. The passage supports which of the following statements about employees buying

shares in their won companies?

A.At three different companies, approximately nine out ten of the workers were

eligible to buy shares in their companies.

B.Approximately 90%of the eligible workers at three different companies chose

to buy shares in their companies.

C.The opportunity to buy shares was discouraged by at least some labor unions.

https://www.sodocs.net/doc/1b17591086.html,panies that demonstrated the highest productivity were the first to allow

their employees the opportunity to buy shares.

20. Which of the following statements is most consistent with the principle described

in L25-26?

A. A democratic government that decides it is inappropriate to own a particular

industry has in no way abdicated its responsibilities as guardian of the public interest.

B.The ideal way for a government to protect employee interests is to force

companies to maintain their share of a competitive market without government subsidies.

C.The failure to harness the power of self-interest is an important reason that

state-owned industries perform poorly

https://www.sodocs.net/doc/1b17591086.html,ernments that want to implement privatization programs must try to

eliminate all resistance to the free-market system.

21. Which of the following can be inferred from the passage about the privatization

process in the United Kingdom?

A.It depends to a potentially dangerous degree on individual ownership of shares.

B.It conforms in its most general outlines to Thomas Paine’s prescription for

business ownership.

C.It was originally conceived to include some giving away of free shares.

D.It is taking place more slowly than some economists suggest is necessary.

22. The quotation in L32-33 is most probably used to .

A.counter a position that the author of the passage believes is incorrect.

B.State a solution to a problem described in the previous sentence.

C.Show how opponents of the viewpoint of the author of the passage have

supported their arguments.

D.point out a paradox contained in a controversial viewpoint.

Passage Four

Questions 23-30 are based on the following passage:

Historians of women’s labor in the United States at first largely disregarded the story of female service workers—women earning wages in occupations such as salesclerk, domestic servant, and office secretary. These historians focused instead on factory work, primarily because it seemed so different from traditional, unpaid ―women’s work ‖in the home, and because the underlying economic forces of industrialism were presumed to be gender-blind and hence emancipation in effect. Unfortunately, emancipation has been less profound than expected, for not even industrial wage labor has escaped continued sex segregation in the workplace.

To explain this unfinished revolution in the status of women, historians have recently begun to emphasize the way a prevailing definition of femininity often determines the kinds of work allocated to women, even when such allocation is inappropriate to new conditions. For instance, early textile-mill entrepreneurs, in justifying women’s employment in wage labor, made much of the assumption that women were by nature skillful at detailed tasks and patient in carrying out repetitive chores; the mill owners thus imported into the new industrial order hoary stereotypes associated with the homemaking activities they presumed to have been the purview of women. Because women accepted the more unattractive new industrial tasks more readily than did men, such jobs came to be regarded as female jobs. And employers, who assumed that women’s ―real‖ aspirations were for

marriage and family life, declined to pay women wages commensurate with those of men. Thus many lower-skilled, lower-paid, less secure jobs came to be perceived as ―female.‖

More remarkable than the origin has been the persistence of such sex segregation in twentieth-century industry. Once an occupation came to be perceived as ―female‖, employers showed surprisingly little interest in changing that perception, even when higher profits beckoned. And despite the urgent need of the United States during the Second World War to mobilize its human resources fully, job segregation by sex characterized even he most important war industries. Moreover, once the war ended, employers quickly returned to men most of the ―male‖ jobs that women had been permitted to master.

23. According to the passage, job segregation by sex in the United States was.

A.greatly diminlated by labor mobilization during the Second World War.

B.perpetuated by those textile-mill owners who argued in favor of women’s

employment in wage labor

C.one means by which women achieved greater job security

D.reluctantly challenged by employers except when the economic advantages

were obvious

24. According to the passage, historians of women’s labor focused on factory work

as a more promising area of research than service-sector work because factory work

A.involved the payment of higher wages

B.required skill in detailed tasks

C.was assumed to be less characterized by sex segregation

D.was more readily accepted by women than by men

25. It can be inferred from the passage the early historians of women’s labor in the

United State s paid little attention to women’s employment in the service sector of the economy because

A.fewer women found employment in the service sector than in factory work

B.the wages paid to workers in the service sector were much more short-term

than in factory work

C.women’s employment in the service sector tended to be much more

short-term than in factory work

D.employment in the service sector seemed to have much in common with the

unpaid work associated with homemaking

26. The passage supports which of the following statements about the early mill

owners mentioned in the second paragraph?

A.They hoped that by creating relatively unattractive ―female‖ jobs they

would discourage women from losing interest in marriage and family life.

B.They sought to increase the size of the available labor force as a means to

keep men’s wages low.

C.They argued that women were inherently suited to do well in particular

kinds of factory work

D.They felt guilty about disturbing the traditional division of labor in family.

27.It can be inferred from the passage that the ―unfinished revolution‖ the author

mentions in L11 refers to the

A.entry of women into the industrial labor market.

B.Development of a new definition of femininity unrelated to the economic

forces of industrialism

C.Introduction of equal pay for equal work in all professions

D.Emancipation of women wage earners from gender-determined job

allocation

28. The passage supports which of the following statements about hiring policies in the United States?

A.After a crisis many formerly ―male ‖jobs are reclassified as ―female‖ jobs.

B.Industrial employers generally prefer to hire women with previous

experience as homemakers

C.Post-Second World War hiring policies caused women to lose many of their

wartime gains in employment opportunity.

D.Even war industries during the Second World War were reluctant to hire

women for factory work.

29. Which of the following words best expresses the opinion of the author of the

passage concerning the notion that women are more skillful than men in

carrying out details tasks?

A.―patient‖ (line17)

B.―repetitive‖ (line18)

C.―hoary‖ (line19)

D.―homemaking‖ (line19)

30. Which of the following best describes the relationship of the final paragraph to

the passage as a whole?

A.The central idea is reinforced by the citation of evidence drawn from

twentieth-century history.

B.The central idea is restated in such a way as to form a transition to a new topic

for discussion

C.The central idea is restated and juxtaposed with evidence that might appear to

contradict it.

D. A partial exception to the generalizations of the central idea is dismissed

unimportant.

Passage Five

Questions 31-36 are based on the following passage:

Two modes of argumentation have been used on behalf of women’s emancipatio n in Western societies. Arguments in what could be called the ―relational‖ feminist tradition maintain the doctrine of ―equality in 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 procreative labor is currently undervalued by society, to the disadvantage of women. By contrast, the individualist 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 responsibilities.

Before the late nineteenth century, these views coexisted within the feminist movement, often within the writings of the same individual. Between 1890and 1920, however, relational feminism, which had been the dominant strain in feminist thought, and which still predominates among European and non-western feminists, lost ground in England and the United States. Because the concept of individual rights was already well established in the Anglo-Saxon legal and political tradition, individualist feminism came to predominate in England-speaking countries. At the same time, the goals of the two approaches began to seem increasingly irreconcilable. Individualist feminists began to advocate a totally gender-blind system with equal educational and economic opportunities outside the home should be available for all women, continued to emphasize women’s special contributions to society as homemakers and mothers; they demanded special treatment including protective legislation for women workers. State-sponsored maternity benefits, and paid compensation for housework.

Relational arguments have a maj or pitfall: because they underline women’s physiological and psychological distinctiveness, they are often appropriated by political adversaries and used to endorse male privilege. But the individualist approach, by attacking gender roles, denying the significance of physiological difference, and condemning existing familial institutions as hopelessly patriarchal, has often simply treated as irrelevant the family roles important to many women. If the individualist framework, with its claim for women’s auton omy, could be harmonized with the family-oriented concerns of relational feminists, a more fruitful model for contemporary feminist politics could emerge.

31. The author of the passage alludes to the well-established nature of the concept of

individual rights in the Anglo-Saxon legal and political tradition in order to

A.illustrate the influence of individualist feminist thought on more general

intellectual trends in English history.

B.Argue that feminism was already a part of the larger Anglo-Saxon intellectual

tradition, even though this has often gone unnoticed by critics of women’s emancipation

C.Explain the decline in individualist thinking among feminists in

non-English-speaking countries.

D.Help account for an increasing shift toward individualist feminism among

feminists in English-speaking countries.

32. The passage suggests that the author of the passage believes which of the

following?

A.The predominance of individualist feminism in English-speaking countries is a

historical phenomenon, the causes of which have not yet been investigated.

B.The individualist and relational feminist views are irreconcilable, given their

theoretical differences concerning the foundations of society.

C. A consensus concerning the direction of future feminist politics will probably

soon emerge, given the awareness among feminists of the need for cooperation

among women.

2012四川大学考博英语真题及答案详解

四川大学2012考博英语真题及答案详解 阅读 1）Sign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique—a speech of the hand. They offer a new way to probe how the brain generates and understands language, and throw new light on an old scientific controversy: whether language, complete with grammar, is something that we are born With, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D. C., the world’s only liberal arts university for deaf people. When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something odd: among themselves, students signed differently from his classroom teacher. Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language (ASL) was thought to be no more than a form of pidgin English (混杂英语). But Stokoe believed the “hand talk” his students used looked richer. He wondered: Might deaf people actually: have a genuine language? And could that language be unlike any other on Earth? I t was 1955, when even deaf people dismissed their signing a s “substandard”. Stokoe’s idea was academic heresy (异端邪说). It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution. For decades educators fought his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation (调节) of sound. But sign language is based on the movement of hands, the modulation of space. “What I said,” Stokoe explains, “is that language is not mouth stuff—it’s brain stuff.” 21. The study of sign language is thought to be _____C___. A) a new way to look at the learning of language B) a challenge to tradi t ional, views on the nature of language C) an approach: to simplifying the grammatical structure of a language D) an attempt to clarify misunderstanding about the origin of language（C） 22. The, present growing interest in sign language was stimulated by ___C_____. A) a famous scholar in the study of the human brain B) a leading specialist in the study of liberal arts C) an English teacher in a university for the deaf D) some senior experts in American Sign Language（C） 23. According to Stokoe, sign language is _____B___. A) a Substandard language B) a genuine language C) an artificial language D) an international language（B）

哈工大博士英语考试冲刺试题三

哈工大博士英语考试冲刺试题三 Passage 1 The realm of product liability is one that has always put legal scholars and practitioners at odds. Viewed by some as genuine efforts to protect the public from dangerous goods and others as an excuse for dirty lawyers to sue rich companies, the matter has yet to be resolved. Product liability, and its implications for disgruntled consumers wishing to sue the makers of what they buy, continues to be debated. Those who argue that current product liability laws are positive assert that without such laws, manufacturers would be free to do as they please without regard for the safety of the consumers who buy their products. As a result, they argue, shoddy merchandise would emerge, with every possible corner cut in order to lower costs, at the expense of quality. Not only would the shoddy merchandise be a rip-off, however, but the products could likely be harmful as well. Proponents of this point of view hail the new wave of warning labels and increased quality assurance that has resulted from recent product liability legislation, confident in their conviction that it has made the American marketplace a safer place to shop. Opponents of the current status-quo, however, cite the overwhelming amount of litigation that has taken place as a result of stricter product liability. A moderate approach id advised by this group, between the necessary safeguards that would prevent abuse of the system by the companies and the excessive consumer-protection laws that allow producers to be sued at the drop of a hat. These people argue that greed and the alluring possibility of easy money lead unscrupulous buyers to look for any excuse to bring minor grievances to court, hoping for a million-dollar outcome. As the situation stands now, the former camp is getting its way, reflecting society's priority of safety over economics. Recent lobbying by producers have begun to shift the tide, however, as abuse of product liability laws continues and grows, courts are beginning to note the trend and take appropriate measures, casting a keener eye on such cases so as to distinguish between frivolous cases and more serious claims.

哈工大考博英语真题及答案

General English Admission Test For Non-English Major Ph.D. program (Harbin Institute of Technology) Passage One Questions 1-7 are based on the following passage: According to a recent theory, Archean-age gold-quartz vein systems were formed over two billion years ago from magmatic fluids that originated from molten granitelike bodies deep beneath the surface of the Earth. This theory is contrary to the widely held view that the systems were deposited from metamorphic fluids, that is, from fluids that formed during the dehydration of wet sedimentary rocks. The recently developed theory has considerable practical importance. Most of the gold deposits discovered during the original gold rushes were exposed at the Earth’s surface and were found because the y had shed trails of alluvial gold that were easily traced by simple prospecting methods. Although these same methods still leas to an occasional discovery, most deposits not yet discovered have gone undetected because they are buried and have no surface expression. The challenge in exploration is therefore to unravel the subsurface geology of an area and pinpoint the position of buried minerals. Methods widely used today include analysis of aerial images that yield a broad geological overview, geophysical techniques that provide data on the magnetic, electrical, and mineralogical properties of the rocks being investigated, and sensitive chemical tests that are able to detect : the subtle chemical halos that often envelop mineralization. However, none of these high-technology methods are of any value if the sites to which they are applied have never mineralized, and to maximize the chances of discovery the explorer must therefore pay particular attention to selecting the ground formations most likely to be mineralized. Such ground selection relies to varying degrees on conceptual models, which take into account theoretical studies of relevant factors. These models are constructed primarily from empirical observations of known mineral deposits and from theories of ore-forming processes. The explorer uses the models to identify those geological features that are critical to the formation of the mineralization being modeled, and then tries to select areas for exploration that exhibit as many of the critical features as possible. 1. The author is primarily concerned with . A. advocating a return to an older methodology. B. explaining the importance of a recent theory. C. enumerating differences between two widely used methods D. describing events leading to a discovery 2. According to passage, the widely held view of Archean-age gold-quartz vein
