  The Context, Meaning and Scope of Tourism

  A Travel has existed since the beginning of time, when primitive man set out, often traversing great distances in search of game, which provided the food and clothing necessary for his survival. Throughout the course of history, people have travelled for purposes of trade, religious conviction, economic gain, war, migration and other equally compelling motivations. In the Roman era, wealthy aristocrats and high government officials also travelled for pleasure. Seaside resorts located at Pompeii and Herculaneum afforded citizens the opportunity to escape to their vacation villas in order to avoid the summer heat of Rome. Travel, except during the Dark Ages, has continued to grow and, throughout recorded history, has played a vital role in the development of civilisations and their economies.

  B Tourism in the mass form as we know it today is a distinctly twentieth-century phenomenon. Historians suggest that the advent of mass tourism began in England during the industrial revolution with the rise of the middle class and the availability of relatively inexpensive transportation. The creation of the commercial airline industry following the Second World War and the subsequent development of the jet aircraft in the 1950s signalled the rapid growth and expansion of international travel. This growth led to the development of a major new industry: tourism. In turn, international tourism became the concern of a number of world governments since it not only provided new employment opportunities but also produced a means of earning foreign exchange.

  C Tourism today has grown significantly in both economic and social importance. In most industrialised countries over the past few years the fastest growth has been seen in the area of services. One of the largest segments of the service industry, although largely unrecognised as an entity in some of these countries, is travel and tourism. According to the World Travel and Tourism Council (1992), ‘Travel and tourism is the largest industry in the world on virtually any economic measure including value-added capital investment, employment and tax contributions’. In 1992, the industry’s gross output was estimated to be $3.5 trillion, over 12 per cent of all consumer spending. The travel and tourism industry is the world’s largest employer with almost 130 million jobs, or almost 7 per cent of all employees. This industry is the world’s leading industrial contributor, producing over 6 per cent of the world’s national product and accounting for capital investment in excess of $422 billion in direct, indirect and personal taxes each year. Thus, tourism has a profound impact both on the world economy and, because of the educative effect of travel and the effects on employment, on society itself.

  D However, the major problems of the travel and tourism industry that have hidden, or obscured, its economic impact are the diversity and fragmentation of the industry itself. The travel industry includes: hotels, motels and other types of accommodation; restaurants and other food services; transportation services and facilities; amusements, attractions and other leisure facilities; gift shops and a large number of other enterprises. Since many of these businesses also serve local residents, the impact of spending by visitors can easily be overlooked or underestimated. In addition, Meis (1992) points out that the tourism industry involves concepts that have remained amorphous to both analysts and decision makers. Moreover, in all nations this problem has made it difficult for the industry to develop any type of reliable or credible tourism information base in order to estimate the contribution it makes to regional, national and global economies. However, the nature of this very diversity makes travel and tourism ideal vehicles for economic development in a wide variety of countries, regions or communities.

  E Once the exclusive province of the wealthy, travel and tourism have become an institutionalised way of life for most of the population. In fact, McIntosh and Goeldner (1990) suggest that tourism has become the largest commodity in international trade for many nations and, for a significant number of other countries, it ranks second or third. For example, tourism is the major source of income in Bermuda, Greece, Italy, Spain, Switzerland and most Caribbean countries. In addition, Hawkins and Ritchie, quoting from data published by the American Express Company, suggest that the travel and tourism industry is the number one ranked employer in the Bahamas, Brazil, Canada, France, (the former) West Germany, Hong Kong, Italy, Jamaica, Japan, Singapore, the United Kingdom and the United States. However, because of problems of definition, which directly affect statistical measurement, it is not possible with any degree of certainty to provide precise, valid or reliable data about the extent of world-wide tourism participation or its economic impact. In many cases, similar difficulties arise when attempts are made to measure domestic tourism.

  READING PASSAGE 2

  You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.

  Autumn leaves

  Canadian writer Jay Ingram investigates the mystery of why leaves turn red in the fall

  A One of the most captivating natural events of the year in many areas throughout North America is the turning of the leaves in the fall. The colours are magnificent, but the question of exactly why some trees turn yellow or orange, and others red or purple, is something which has long puzzled scientists.

  B Summer leaves are green because they are full of chlorophyll, the molecule that captures sunlight and converts that energy into new building materials for the tree. As fall approaches in the northern hemisphere, the amount of solar energy available declines considerably. For many trees — evergreen conifers being an exception — the best strategy is to abandon photosynthesis_until the spring. So rather than maintaining the now redundant leaves throughout the winter, the tree saves its precious resources and discards them. But before letting its leaves go, the tree dismantles their chlorophyll molecules and ships their valuable nitrogen back into the twigs. As chlorophyll is depleted, other colours that have been dominated by it throughout the summer begin to be revealed. This unmasking explains the autumn colours of yellow and orange, but not the brilliant reds and purples of trees such as the maple or sumac.

  C The source of the red is widely known: it is created by anthocyanins, water-soluble plant pigments reflecting the red to blue range of the visible spectrum. They belong to a class of sugar-based chemical compounds also known as flavonoids. What’s puzzling is that anthocyanins are actually newly minted, made in the leaves at the same time as the tree is preparing to drop them. But it is hard to make sense of the manufacture of anthocyanins — why should a tree bother making new chemicals in its leaves when it’s already scrambling to withdraw and preserve the ones already there?

  D Some theories about anthocyanins have argued that they might act as a chemical defence against attacks by insects or fungi, or that they might attract fruit-eating birds or increase a leaf’s tolerance to freezing. However there are problems with each of these theories, including the fact that leaves are red for such a relatively short period that the expense of energy needed to manufacture the anthocyanins would outweigh any anti-fungal or anti-herbivore activity achieved.

  _photosynthesis: the production of new material from sunlight, water and carbon dioxide

  E It has also been proposed that trees may produce vivid red colours to convince herbivorous insects that they are healthy and robust and would be easily able to mount chemical defences against infestation. If insects paid attention to such advertisements, they might be prompted to lay their eggs on a duller, and presumably less resistant host. The flaw in this theory lies in the lack of proof to support it. No one has as yet ascertained whether more robust trees sport the brightest leaves, or whether insects make choices according to colour intensity.

  F Perhaps the most plausible suggestion as to why leaves would go to the trouble of making anthocyanins when they’re busy packing up for the winter is the theory known as the ‘light screen’ hypothesis. It sounds paradoxical, because the idea behind this hypothesis is that the red pigment is made in autumn leaves to protect chlorophyll, the light-absorbing chemical, from too much light. Why does chlorophyll need protection when it is the natural world’s supreme light absorber? Why protect chlorophyll at a time when the tree is breaking it down to salvage as much of it as possible?

  G Chlorophyll, although exquisitely evolved to capture the energy of sunlight, can sometimes be overwhelmed by it, especially in situations of drought, low temperatures, or nutrient deficiency. Moreover, the problem of oversensitivity to light is even more acute in the fall, when the leaf is busy preparing for winter by dismantling its internal machinery. The energy absorbed by the chlorophyll molecules of the unstable autumn leaf is not immediately channelled into useful products and processes, as it would be in an intact summer leaf. The weakened fall leaf then becomes vulnerable to the highly destructive effects of the oxygen created by the excited chlorophyll molecules.

  H Even if you had never suspected that this is what was going on when leaves turn red, there are clues out there. One is straightforward: on many trees, the leaves that are the reddest are those on the side of the tree which gets most sun. Not only that, but the red is brighter on the upper side of the leaf. It has also been recognised for decades that the best conditions for intense red colours are dry, sunny days and cool nights, conditions that nicely match those that make leaves susceptible to excess light. And finally, trees such as maples usually get much redder the more north you travel in the northern hemisphere. It’s colder there, they’re more stressed, their chlorophyll is more sensitive and it needs more sunblock.

  I What is still not fully understood, however, is why some trees resort to producing red pigments while others don’t bother, and simply reveal their orange or yellow hues. Do these trees have other means at their disposal to prevent overexposure to light in autumn? Their story, though not as spectacular to the eye, will surely turn out to be as subtle and as complex.

  Beyond the blue horizon

  Ancient voyagers who settled the far-flung islands of the Pacific Ocean

  An important archaeological discovery on the island of Efate in the Pacific archipelago of Vanuatu has revealed traces of an ancient seafaring people, the distant ancestors of today’s Polynesians. The site came to light only by chance. An agricultural worker, digging in the grounds of a derelict plantation, scraped open a grave — the first of dozens in a burial ground some 3,000 years old. It is the oldest cemetery ever found in the Pacific islands, and it harbors the remains of an ancient people archaeologists call the Lapita.

  They were daring blue-water adventurers who used basic canoes to rove across the ocean. But they were not just explorers. They were also pioneers who carried with them everything they would need to build new lives — their livestock, taro seedlings and stone tools. Within the span of several centuries, the Lapita stretched the boundaries of their world from the jungle-clad volcanoes of Papua New Guinea to the loneliest coral outliers of Tonga.

  The Lapita left precious few clues about themselves, but Efate expands the volume of data available to researchers dramatically. The remains of 62 individuals have been uncovered so far, and archaeologists were also thrilled to find six complete Lapita pots. Other items included a Lapita burial urn with modeled birds arranged on the rim as though peering down at the human remains sealed inside. ‘It’s an important discovery,’ says Matthew Spriggs, professor of archaeology at the Australian National University and head of the international team digging up the site, ‘for it conclusively identifies the remains as Lapita.’

  DNA teased from these human remains may help answer one of the most puzzling questions in Pacific anthropology: did all Pacific islanders spring from one source or many? Was there only one outward migration from a single point in Asia, or several from different points? ‘This represents the best opportunity we’ve had yet,’ says Spriggs, ‘to find out who the Lapita actually were, where they came from, and who their closest descendants are today.’

  There is one stubborn question for which archaeology has yet to provide any answers: how did the Lapita accomplish the ancient equivalent of a moon landing, many times over? No-one has found one of their canoes or any rigging, which could reveal how the canoes were sailed. Nor do the oral histories and traditions of later Polynesians offer any insights, for they turn into myths long before they reach as far back in time as the Lapita.

  ‘All we can say for certain is that the Lapita had canoes that were capable of ocean voyages, and they had the ability to sail them,’ says Geoff Irwin, a professor of archaeology at the University of Auckland. Those sailing skills, he says, were developed and passed down over thousands of years by earlier mariners who worked their way through the archipelagoes of the western Pacific, making short crossings to nearby islands. The real adventure didn’t begin, however, until their Lapita descendants sailed out of sight of land, with empty horizons on every side. This must have been as difficult for them as landing on the moon is for us today. Certainly it distinguished them from their ancestors, but what gave them the courage to launch out on such risky voyages?

  The Lapita’s thrust into the Pacific was eastward, against the prevailing trade winds, Irwin notes. Those nagging headwinds, he argues, may have been the key to their success. ‘They could sail out for days into the unknown and assess the area, secure in the knowledge that if they didn’t find anything, they could turn about and catch a swift ride back on the trade winds. This is what would have made the whole thing work.’ Once out there, skilled seafarers would have detected abundant leads to follow to land: seabirds, coconuts and twigs carried out to sea by the tides, and the afternoon pile-up of clouds on the horizon which often indicates an island in the distance.

  For returning explorers, successful or not, the geography of their own archipelagoes would have provided a safety net. Without this to go by, overshooting their home ports, getting lost and sailing off into eternity would have been all too easy. Vanuatu, for example, stretches more than 500 miles in a northwest-southeast trend, its scores of intervisible islands forming a backstop for mariners riding the trade winds home.

  All this presupposes one essential detail, says Atholl Anderson, professor of prehistory at the Australian National University: the Lapita had mastered the advanced art of sailing against the wind. ‘And there’s no proof they could do any such thing,’ Anderson says. ‘There has been this assumption they did, and people have built canoes to re-create those early voyages based on that assumption. But nobody has any idea what their canoes looked like or how they were rigged.’

  Rather than give all the credit to human skill, Anderson invokes the winds of chance. El Nino, the same climate disruption that affects the Pacific today, may have helped scatter the Lapita, Anderson suggests. He points out that climate data obtained from slow-growing corals around the Pacific indicate a series of unusually frequent El Ninos around the time of the Lapita expansion. By reversing the regular east-to-west flow of the trade winds for weeks at a time, these ‘super El Ninos’ might have taken the Lapita on long unplanned voyages.

  However they did it, the Lapita spread themselves a third of the way across the Pacific, then called it quits for reasons known only to them. Ahead lay the vast emptiness of the central Pacific and perhaps they were too thinly stretched to venture farther. They probably never numbered more than a few thousand in total, and in their rapid migration eastward they encountered hundreds of islands — more than 300 in Fiji alone.

  Write the correct letter, A-J, in boxes 27-31 on your sheet.

  The Efate burial site

  A 3,000-year-old burial ground of a seafaring people called the Lapita has been found on an abandoned 27 on the Pacific island of Efate. The cemetery, which is a significant 28 , was uncovered accidentally by an agricultural worker.

  The Lapita explored and colonised many Pacific islands over several centuries. They took many things with them on their voyages including 29 and tools.

  The burial ground increases the amount of information about the Lapita available to scientists. A team of researchers, led by Matthew Spriggs from the Australian National University, are helping with the excavation of the site. Spriggs believes the 30 which was found at the site is very important since it confirms that the 31 found inside are Lapita.

  Passage 1参考译文:

  旅游的背景,意义和范畴

  A. 自从上帝创造了万物以来,旅行就已经存在了:那时原始人启程,常常穿越很远的距离搜寻猎物,这些猎物提供了生存所必需的食物以及衣物。贯穿人类历史,人类为了贸易、宗教信仰、经济所得、战争、移民以及其他同样具有吸引力的动机而旅行。在罗马时代,独有的贵族以及高级政府官员同样为了享乐而旅行。坐落在Pompeii和Herculaneum的海边度假胜地给人们提供了一个逃离到度假别墅的机会,从而避免了罗马夏日的酷暑。除了在黑暗时代,旅游是一直在发展的,而且人类历史自从有记录以来,旅游在文明发展以及经济发展当中起到了极为关键的作用。

  B.如今,我们知道的大众旅游的形式是20世纪独有的现象。历史学家们认为,大众旅游的出现开始于英国工业革命时期,因为它伴随着中产阶级的崛起和容易获取到的相对廉价的交通方式。第二次世界大战过后的商业、航空工业的创造以及之后20世纪60年代的喷气式飞机的发展,标志着跨国旅游的快速增长与扩张。这种增长导致了一个主要的新的工业的发展:旅游业。反过来,国际旅游的发展成为众多国家的要事,因为它不仅提供了新的就业机会,也产生了创造外汇的新途径。

  C.今天,在经济以及社会价值方面,旅游业地位都显著提升。大多教的工业化国家在过去的几十年,都在服务业领域经历了最快速的发展。尽管在有些国家当中,旅行和旅游业在很大程度上并不被认为是一个实体,但他们却是服务业最大的几个板块之一。根据世界旅游与旅游协会的资料(1992),‘几乎用任何一种经济指标衡量,旅行和旅游业都是世界上最大的产业,这些指标包括增值资本投资、就业以及税收贡献。’在1992年,工业总产值估计为3.5万亿美元,比全部消费支出的12%还要多。创造了 1.3亿个就业岗位(差不多全部就业人口的7%),旅行和旅游业雇佣的人数最多。这一产业是世界领先的产业贡献者,每年它产出了超过6%的世界国民生产总值,占据了超过来源于直接、间接以及个人税收4220亿美金的资本投资。因此,旅游业不仅对世界经济有着深远的影响,而且由于旅游的教育性意义和对就业的作用,对社会本身也有深远的影响。

  D.旅行和旅游业隐藏了或者模糊了它的经济影响,其主要问题是这一工业的多样性与不完整性。旅游产业包括:酒店、汽车旅馆和其他形式的住宿业;餐厅以及其他形式的食物供应行业;交通服务以及设施;游乐场、旅游景点、和其他休闲设施;礼品商店以及大量的其他企业。因为很多这些企业也服务本地居民,游客消费的影响容易被忽略或者低估。另外,Meis (1992)指出旅游业涉及一些对于分析家以及政策制定者而言都觉得无定形的、抽象的概念。更进一步说,在所有国家,这一问题使得旅游业难以开发任何形式的有效而可信的旅游信息库来测算旅游业对地区、国家甚至全球的经济贡献。但是这种多样性的本质使得旅行和旅游业成为许多国家、地区或者是社群经济发展的理想工具。

  E.旅行和旅游业过去曾经是有钱人独享的领城,现在却已成为大多数人习惯的生活方式。事实上,McIntosh和Goeldner (1990)指出,对于很多国家,旅游业已成了跨国贸易中的最大的商品,对于其他一定数量的国家而言,旅游业也排在了第二位或第三位。例如,旅游业是百慕大、希腊、意大利、西班牙、瑞士和大多数加勒比海国家的最大收入来源。另外,Hawkins和Ritchie引用美国运通公司的数据,指出旅行和旅游产业在巴哈马、巴西、加拿大、法国、(前)西德、香港、意大利、牙买加、日本、新加坡、英国、美国是雇佣员工最多的产业。但是由于定义的问题直接影响到了统计性的测量,确定地提出精确、有效、可靠的关于世界范围旅游业参与程度以及其经济影响的数据是不大可能的。在很多情况下,当人们试图测量国内的旅游业时,相似的问题也出现了。

  秋叶

  加拿大作家Jay Ingram调查树叶在秋关变红的秘密

  A.每年北美多个地区里最为迷人的自然事件之一,就是秋叶变色之时。叶子的颜色都很壮观美丽,但一个确切的问题还久久地困扰着科学家们,就是为什么一些树会变成黄色或橙色,而 其他树则变为红色或紫色。

  B.夏天树叶是绿色的,因为它们有足够的叶绿素,而这些分子能捕捉到阳光,并将其转化成作为树木生长新原料的能量。当北半球秋天临近时,太阳能的可利用成分会大量地减少。对于很多树种来说——常绿松柏类植物是个例外——最好的应对措施是停止光合作用,直到春天到来。所以,树木与其在整个冬天里保留现有的多余叶子,倒不如保存珍贵的养料而丢弃它们。但在这些叶子凋落之前,树木会拆分它们的叶绿素分子,并将这些分子内有用的氮传送回细枝里。一旦叶绿素被耗尽,在夏天里因叶绿素的主导作用,而被抑制的其他颜色便开始显现。这个发现解释了秋叶的黄与橙,却并未解释出如同枫树和漆树一般的灿烂的红色和紫色。

  C. 红色的原料是众所周知的:它由不同的花青素提炼出来,一种在可见光谱中能显现红到蓝的水溶性植物色素。他们属于一个级别的糖本化合物,也称之为类黄酮。令人困惑的是花青素是新制成的,即树木准备让叶子凋零的时候才在叶子中生成。但树木生成花青素的行为难以被理解一为什么树木在它现有的叶子中吸收和保存花青素,还要忙着在叶子里制作新的这种化学物质?

  D. 一些关于花青素的理论认为它们是用作防止昆虫和真菌伤害的化学防御,或是用于吸引以食果类为生的鸟类,或是增大叶子的耐寒能力。然而这些理论个个都存在问题,包括下面的事实:叶子保持红色的时期如此之短,以至于在该时期内制造花青素所需消耗的能量大于任何抗菌或抵抗食草动物活动所需的能量。

  E. 它(理论)也建议,树木可以生成鲜艳的红色,让食草昆虫相信他们自身是健康强壮的,并能轻易地增加化学防御来抵抗感染。如果昆虫们注意到这些树木类似的“宣传”信心,它们可能更多地在一些暗沉的,抵挡性较弱的寄主上产卵。这个理论上的错误就在于缺乏事实依据的支撑。到现在为止,没有人能确定是否越强壮的树越能展示出明亮的树叶,或昆虫是否会根据颜色亮度来选择树木。

  F. 或许看似最有理的推断是一个被称为“光屏”的假设。该假设解释了为什么叶子在忙着准备过冬时,不顾麻烦也去制造花青素。这听起来是矛盾的,因为这假设背后的想法是红色素是在秋叶中生成的,以此来保护叶绿素,这个吸光化学物,免受过强光源的伤害。为什么叶绿素需要保护,当它是自然界中最优质的光源吸收体?为什么正是树木折断需被抢救时要 尽可能保护叶绿素?

  G.尽管精妙地参与到捕捉太阳光能量的过程中,叶绿素有时也会被破坏,特别是当环境是干燥、低温或营养缺失时。这时的叶子正忙碌地为过冬分解内在机制。由摇摇欲坠的秋叶中的叶绿素分子吸收而来的能量,并不能立即被传送到有用的产物和过程中,因为它将构成一片完整的夏叶。老弱的秋叶是由活跃的叶绿素分子造成的,因受具有摧毁性作用的氧化影响而变得容易残破。

  H. 即便你不曾怀疑叶子变红时发生了什么,但迹象已经摆在眼前。首先能明确的是:对于许多树而言,最红的叶子都是在树木近阳的一面。不仅这样,最发亮的红也出现在叶子的最顶端。为世代所认识的是,对于形成深红颜色的最佳条件是干燥、晴天和凉爽的夜晚,这是让叶子最大程度吸光的最佳条件。最后,如例如枫树一般的树木在北半球越北的地方,叶子就会越红。那里更冷, 树木会感到更有压迫,而它们的叶绿素也会更敏感,需要更多的阳光。

  I.然而,仍未探明的是为什么一些树木借助生成红色素,而其他则不用,就能轻易地显示出他们的黄橙色调。是那些树有别的解决方法去阻挡在秋天的过分暴晒吗?他们的故事,或许在我们眼里并不惊人,但必定精妙而复杂。

  蓝色海平线外

  居住在太平洋遥远岛屿上的古代航行者

  一项关于太平洋Vanuatu群岛上的岛的重要考古发现,揭开了一个古老的航海种族的行踪,该种族恰恰也是今天Polynesians亚种族的远古祖先。Efate岛是偶然被世人发现的。一位农业工作者,在挖掘一个被废弃的种植园时,挖开了一个坟墓,而该坟墓仅是一块大约有3000年历史的墓地上数十个坟墓中的第一个。 这是在太平洋群岛上至今为止发现的最古老的墓地,它里面躺着一个远古种族的众多遗体。考古学家们称该种族为Lapita。

  Lapita种族是勇敢的蓝色大海上的冒险者,他们曾经用简单的独木舟穿越海洋。但是他们不仅仅是探险者。他们也是开拓者,携带了一切需要的物品来创建新生活,这些物品包括他们的家畜,芋头幼苗和石具。在长达几个世纪的时间里,种族把他们世界的边界,从Papua New Guinea岛上覆盖着丛林的火山群,延伸到汤加群岛上最孤寂的布满珊瑚的外围地带。

  Lipita种族仅仅留下可几条关于自身的宝贵线索,但是Efate岛大大地扩充了对研究象来说有用数据量。62位Lapita人的遗体至今经被挖掘出来了,考古学家们同时也非常激动地发现了六个完整的陶罐。其他发掘出的物品包括一个Lipita人的骨灰瓮,瓮的边缘散布着仿制的小鸟,仿佛在向下凝视着密封在里面的Lapita的遗体。“这是个重要的发现,”澳大利亚国立大学考古学教授兼挖掘场地的国际团队的总负责人Matthew Spriggs表成“因为它令人信服地确定了遗体便是Lapita种族。”

  从这些人类遗体中提取出来的DNA可能能够帮助解答其中一个在太平洋人类学中最让人困惑的问题,即所有的太平洋岛上居民来源于一个祖先还是多个。是只有一批来自亚洲某个地方的外来移民, 还是有若千批来自不同地方的外来移民?

  “Efate岛的发现是我们有史以来最好的机会,” Sprigg说道,“来探索Lapita种族到底是怎么样的种族,他们来自哪里,以及当今与他们关系最紧密的后代是哪些种族。”

  这里还有一个棘手的问题,考古学至今提供不了多少答案,即Lapita人是怎么样在远古时期完成相当于月球登陆般艰难的穿越海洋的行动,而且还那么多次? 至今没有人发现一艘他们的独木舟或任何绳索,以此来发现他们的独木舟是如何航行的。同时在后来的Polynesians人的口头相传的历史故事和传统中也没能提供什么相关线索,因为在这些故事传统流传到Lapita那个时期以前,就已经变成神话传说了。

  “我们可以确定的是Lapita人那时候已经有能够开展海洋航行的独木舟了,并且他们有能力行驶独木舟。”奥克兰大学的考古学教授Geoff Irwin表示。他说道,那些航行技能被早期航海人员发展并流传了数千年,这些早期的航海人员靠自己想方设法穿越了西部太平洋的群岛,开辟了通向邻近岛屿的短路线。然而,真正的冒险还没开始,直到他们的后裔行驶出大陆的视线范围,大陆变得每个方向都没有界限。而这肯定对他们来说很困难,如同当今我们登陆月球一样。当然这样的穿越举动使得他们从他们的祖先中突显出来,但是是什么给了他们勇气发起如此危险的航行之旅呢?

  Irwin指出,Lapita人进入太平洋的航向是向东的,这不同于通常的顺风。他同时表明,这样艰难的逆风航行方式,也许正是也们成功的关键。“他们能够行驶数天进入未知‘和可以到达的’地带,因为他们确定地知道如果一无所获,他们能够转向乘着顺风快速返这正是促成整个探索行动成功的关键。”一旦出行,有经验的海员能够观测并跟随大量的指引线索到达新大陆,比如海鸟,被潮汐冲入大海的椰子和细枝,和下午海平线上堆积的云层,这些云层通常代表不远处有海岛。

  对于返航的探险者,不论成功与否,他们自己群岛的地形就已经提供了一个保障安全的网罩。如果在途中没有这个安全的网罩,航行偏离他们自己的港口,迷失甚至是行驶向死亡之路将变得很容易发生。比如,Vanuatu岛,在西北到东南方向上长度达500多英里,它众多相互可见的岛屿,为乘着顺风返航的航海员们形成增援,保护着他们。

  所有这些预设了一个重要的细节点,澳大利亚国立大学的史前时期研究教授Atholl Anderson说道, Lapita人已经早早地掌握了先进的逆风航行的技能。 “并没有证据证明他们能够做这样的事情,” Anderson表示,“但这里已经假设他们能够这样做,同时基于这样的假设,人们已经制作独木舟来再次开展那些早期的航海探险。但是没有人知道他们的独木舟到底是怎么样的或者他们是怎么样装配索具。”

  与其全部归功于人类的技能,也得“考虑到自然风力产生的可能性”,Anderson表示。厄尔尼诺现象,如今影响太平洋的这一异常气候,也许曾帮助分散Lapita人群的分布。他指出从太平洋周围生长缓慢的珊瑚中获取的气候数据暗示着大概在Lapita人对外扩张时期,存在一系列不平常且频繁的厄尔尼诺现象。通过反转一般东西流向的顺风且每次长达数周,这些超级厄年尼诺现象大概已经促使Lapita人开始漫长且未计划过的航行之旅。

  但是他们做到了,Lapita人分布在太平洋三分之一的岛屿上,之后由于若干只有他们知道的原因,停止了对外探索。前方太平洋中部有着大片仍未被开发的领域,也许他们太薄弱而无法继续往前探索扩张。可能总共人数算起来从未超过几千人, 在他们向东的快速迁徙过程中,他们遇见了成百上千的岛屿,单单在斐济就有300多个岛屿。
