09雅思阅读题源精读 | PAPYRUS-纸莎草系列【2】雅思阅读Vol.09PAPYRUS————————————前情回顾：之前江鸟大哥对于下面的这篇纸莎草已经分析完了开头段，如果感兴趣，可以戳《PAPYRUS-纸莎草系列【2】Used by the ancient Egyptians to make paper, the papyrus plant hashelped to shape the world we live in上篇文章我们分析了开头2段，逻辑流动是：【step 1】从第一句的回溯历史，各种documents文献记录都非常重要。

【step 2】于是提出记录的载体是非常重要的。

【step 3】进而引出不同时间段，不同文明选用的记录载体【step 3】最后引出纸莎草的重要性。

【第三段】既然前两段已经吊足了读者胃口，从过去古文明，到纸莎草的重要性，接下来我们的主角就要闪亮登场：纸莎草Papyrus is strongly associated with Egyptianculture, although all the ancient civilization around the Mediterranean usedit.译文：尽管地中海周边所有的古文明都在使用纸莎草，但是它一般都是与埃及文化息息相关。

The papyrus sedge is a tall grass-like plant.It was harvested from shallow water and swamplands on the banks of the RiverNile. Manufacturing sheets of papyrus from papyrus sedge was a complex, messyprocess. Pith from inside the plant’s stem was cut into long strips that werelaid side by side. These were then covered with a second layer of strips whichwere laid at right angles to the first, then soaked in water and hammeredtogether. The sheet was then crushed to extract the water, dried and thenpolished to produce a high-quality writing surface. Individual sheets could beglued together and rolled up to make scrolls or folded and bound toform books.The papyrus sedge is a tall grass-like plant.莎草是一个像草一样的高植株*莎草：纸莎草的原料接下来的这些句子，单词就有些难度。

Origin of Species & Continent Formation A T he fact that there was once a Pangean supercontinent, a PanthalassaOcean, and a Tethys Ocean, has profound implications for the evolution of multicellular life on Earth. These considerations were unknown to the scientists of the 19th century—making their scienti fi c deductions even more remarkable. Quite independently of each other, Charles Darwin and his young contemporary Alfred Russel Wallace reached the conclusion that life had evolved by natural selection. Wallace later wrote in My Life of his own inspiration:B W hy do some species die and some live? The answer was clearly that onthe whole the best fitted lived. From the effects of disease the most healthy escaped;from enemies the strongest, the swiftest or the most cunning from famine the best hunters…then it suddenly fl ashed on me that this self-acting process would improve the race, because in every generation the inferior would inevitably be killed off and the superior would remain, that is , the fi ttest would survive.C B oth Darwin’s and Wallace’s ideas about natural selection had been in fl uencedby the essays of Thomas Malthus in his Principles of Population. Their conclusions, however, had been the direct result of their personal observation of animals and plants in widely separated geographic locations:Darwin from his experiences during the voyage of the Beagle, and particularly during the ship’s visit to the Galapagos Islands in the East Paci fi c in 1835; Wallace during his years of travel in the Amazon Basin andin the Indonesia-Australian Archipelago inthe 1850s.D D arwin had been documenting his ideas onnatural selection for many years when hereceived a paper on this selfsame subjectfrom Wallace, who asked for Darwin’s opinion and help in getting it published.In July 1858, Charles Lyell and J. D Hooker, close friends of Darwin, pressed Darwin to present his conclusions so that he would not lose priority to and unknown naturalist. Presiding over the hastily called but now historic meeting of the Linnean Society in London, Lyell and Hooker explained to the distinguished members how “these two gentlemen” (who were absent:Wallace was abroad and Darwin chose not to attend), had “independently and unknown to one another, conceived the same very ingenious theory, ”E B oth Darwin and Wallace had realized that the anomalous distributionof species in particular regions had profound evolutionary significance.Subsequently, Darwin spent the rest of his days in almost total seclusion thinking and writing mainly about the origin of species. In contrast, Wallace applied himself to the science of biogeography, the study of the pattern and distribution of species, and its significance, resulting in the publication of a massive two-volume work the Geographical Distribution of Animals in 1876.F W allace was a gentle and modest man, but also persistent and quietlycourageous. He spent years working in the most arduous possible climates and terrains, particularly in the Malay archipelago, he made patient and detailed zoological observations and collected huge number of specimens for museums and collectors-which is how he made a living. One result of his work was the conclusion that there is a distinct faunal boundary, called “Wallace’s line, “between an Asian realm of animals in Java, Borneo and the Philipiones and an Australian realm in New Guinea and Australia. In essence this boundary posed a dif fi cult question: How on Earth did plants and animals with a clearaffinity to the Northern Hemisphere meet with their Southern Hemispheric counterparts along such a distinct Malaysian demarcation zone? Wallace was uncertain about demarcation on one particular island-Celebes, a curiously shaped place that is midway between the two groups. Initially he assigned its fl ora-fauna to the Australian side of the line, but later he transferred it to theAsian side. Today we know the reason for his dilemma. 200MYA East and West Celebes were islands with their own natural history lying on opposite sides of the Tethys Ocean. They did not collide until about 15 MYA. The answer to the main question is that Wallace’s Line categorizes Laurasia-derived flora-fauna (the Asian) and Gondwana-derived flora-fauna (the Australian), fauna that had evolved on opposing shares of the Tethys. The closure of the Tethys Ocean today is manifested by the ongoing collision of Australia/New Guinea with Indochina/Indonesia and the continuing closure of the Mediterranean Sea—a remnant of the Western Tethys Ocean.G I n his origin of continents and oceans, Wegener quoted at length fromWallace’s Geographical Distribution of Animals. According to Wegener’s reading, Wallace had identified three clear divisions of Australian animals, which supported his own theory of continental displacement. Wallace had shown that animals long established in southwestern Australia had an af fi nity with animals in South Africa, Madagascar, India, and Ceylon, but did not have an af fi nity with those in Asia. Wallace also showed that Australian marsupialsand monotremes are clearly related tothose in South America, the Moluccas,and various Pacific islands, and that noneare found in neighboring Indonesia. Fromthis and related data, Wegener concluded that the then broadly accepted “landbridge” theory could not account for this distribution of animals and that only his theory of continental drift could explain it.H T he theory that Wegener dismissed in preference to his own proposed thatplants and animals had once migrated across now-submerged intercontinental landbridges. In 1885, one of Europe’ s leading geologists, Eduard Suess, theorized that as the rigid Earth cools, its upper crust shrinks and wrinkles like the withering skin of an aging apple. He suggested that the planet’s seas and oceans now fi ll the wrinkles between once-contiguous plateaus.I T oday, we know that we live on a dynamic Earth with shifting, colliding andseparating tectonic plates, not a “withering skin”, and the main debate in the fi eld of biogeography has shifted. The discussion now concerns “ dispersalism”versus “vicarianism: unrestricted radiation of species on the one hand and thedevelopment of barriers to migration on the other. Dispersion is a short-term phenomenon—the daily or seasonal migration of species and their radiation to the limits of their natural environment on an extensive and continuous landmass. Vicarian evolution, however, depends upon the separation and isolation of a variety of species within the con fi nes of natural barriers in the form of islands, lakes, or shallow seas—topographical features that take a long time to develop.Questions 1-5 .................................................................................Use the information in the passage to match the people (listed A-E) with opinions or deeds below.

雅思阅读动植物类真题及答案：ThePearl做好雅思的阅读题除了把握对的〔方法〕，也离不开我们日常的辛勤练习，下面我给大家带来雅思阅读动〔植物类〕真题及答案：The Pearl，一起加油吧！雅思阅读动植物类真题：The PearlThe PearlAThroughout history, pearls have held a unique presence within the wealthy and powerful. For instance, the pearl was the favored gem of the wealthy during the Roman Empire. This gift from the sea had been brought back fromthe orient by the Roman conquests. Roman women wore pearls to bed so they could be reminded of their wealth immediately upon waking up. Before jewelers learned to cut gems, the pearl was of greater value than the diamond.In the Orient and Persia Empire, pearls were ground into powders to cure anything from heart disease to epilepsy, with possible aphrodisiac uses as well.Pearls were once considered an exclusive privilege for royalty. A law in 1612drawn up by the Duke of Saxony prohibited the wearing of pearls by nobility,professors, doctors or their wives in an effort to further distinguish royalappearance. American Indians also used freshwater pearls from the MississippiRiver as decorations and jewelry.BThere are essentially three types of pearls: natural, cultured and imitation. Anatural pearl (often called an Oriental pearl) forms when an irritant, such asa piece of sand, works its way into a particular species of oyster, mussel, orclam. As a defense mechanism, the mollusk secretes a fluid to coat the irritant.Layer upon layer of this coating is deposited on the irritant until a lustrouspearl is formed.CThe only difference natural pearls and cultured pearls is that the irritant isa surgically implanted bead or piece of shell called Mother of Pearl. Often, these shells are ground oyster shells that are worthsignificant amounts of money in their own right asirritant-catalysts for quality pearls. The resultingcore is, much larger than in a natural pearl. Yet,as long as there are enough layers of nacre (thesecreted fluid covering the irritant) to result in abeautiful, gem-quality pearl, the size of the nucleusis of no consequence to beauty or durability.DPearls can come from either salt or freshwater sources. Typically, saltwaterpearls tend to be higher quality, although there are several types of freshwaterpearls that are considered high in quality as well. Freshwater pearlstend tobe very irregular in shape, with a puffed rice appearance the most prevalent.Nevertheless, it is each individual pearls merits that determines value morethan the source of the pearl. Saltwater pearl oysters are usually cultivated inprotected lagoons or volcanic atolls. However, most freshwater cultured pearlssold today come from China. Cultured pearls are the response of the shell to atissue implant. A tiny piece of mantle tissue from a donor shell is transplantedinto a recipient shell. This graft will form a pearl sac and the tissue willprecipitate calcium carbonate into this pocket. There are a number of optionsfor producing cultured pearls: use freshwater or seawater shells, transplantthe graft into the mantle or into the gonad, add a spherical bead or do it nonbeaded.The majority of saltwater cultured pearls are grown with beads.ERegardless of the method used to acquire a pearl, the process usually takesseveral years. Mussels must reach a mature age, which can take up t0 3 years,and then be implanted or naturally receive an irritant. Once the irritantisin place, it can take up to another 3 years for the pearl to reach its full size.Often, the irritant may be rejected, the pearl will be terrifically misshapen, orthe oyster may simply die from disease orcountless other complications. By the endof a 5 t0 10 year cycle, only 50% of theoysters will have survived. And of the pearlsproduced, only approximately 5% are ofsubstantial quality for top jewelry makers.From the outset, a pearl fanner can figureon spending over $100 for every oysterthat is farmed, of which many will produce nothing or die.FImitation pearls are a different storyaltogether. In most cases, a glass bead isdipped into a solution made from fishscales. This coating is thin and mayeventually wear off. One can usuallytell an imitation by biting on it. Fakepearls glide across your teeth, while thelayers of nacre on real pearls feel gritty.The Island of Mallorca (in Spain) is known for its imitation pearl industry.Quality natural pearls are very rare jewels. The actual value of a natural pearlis determined in the same way as it would be for other “precious” gems. The valuation factors include size, shape, color, quality of surface, orientand luster. In general, cultured pearls are less valuable than natural pearls,whereas imitation pearls almost have no value. One way that jewelers can determine whether a pearl is cultured or natural is to have a gem lab performan x-ray of the pearl. If the x-ray reveals a nucleus, the pearl is likely a beadnucleatedsaltwater pearl. If no nucleus is present, but irregular and small dark inner spots indicating a cavity are visible, combined with concentric rings oforganic substance, the pearl is likely a cultured freshwater. Cultured freshwaterpearls can often be confused for natural pearls which present as homogeneouspictures which continuously darken toward the surface of the pearl. Naturalpearls will often show larger cavities where organic matter has dried out anddecomposed. Although imitation pearls look the part, they do not have thesame weight or smoothness as real pearls, and their luster will also dim greatly.Among cultured pearls, Akoya pearls from Japan are some of the most lustrous.A good quality necklace of 40 Akoya pearls measuring 7mm in diametersellsfor about $1,500, while a super- high quality strand sells for about $4,500. Sizeon the other hand, has to do with the age of the oyster that created the pearl (themore mature oysters produce larger pearls) and the location in which the pearlwas cultured. The South Sea waters of Australia tend to produce the larger pearls; probably because the water along the coast line is supplied with richnutrients from the ocean floor. Also, the type of mussel common to the areaseems to possess a predilection for producing comparatively large pearls.G Historically, the world’s best pearls came from the Persian Gulf, especiallyaround what is now Bahrain. The pearls of the Persian Gulf were natural created and collected by breath-hold divers. The secret to the special luster ofGulf pearls probably derived from the unique mixture of sweet and salt wateraround the island. Unfortunately, the natural pearl industry of the Persian Gulfended abruptly in the early 1930’s with the discovery of large deposits ofoil. Those who once dove for pearls sought prosperity in the economic boomushered in by the oil industry. The water pollution resulting fromspilled oiland indiscriminate over-fishing of oysters essentially ruined the once pristinepearl producing waters of the Gulf. Today, pearl diving is practiced only asa hobby. Still, Bahrain remains one of the foremost trading centers for highquality pearls. In fact, cultured pearls are banned from the Bahrain pearl market, in an effort to preserve the location’s heritage. Nowadays, the largeststock of natural pearls probably resides in India. Ironically, much of India’sstock of natural pearls came originally from Bahrain. Unlike Bahrain, which has essentially lost its pearl resource, traditional pearl fishing is still practicedon a small scale in India.雅思阅读真题答案解析——pearl珠宝1 A【原文参考根据-A】第2句话 the pearl was the favored gem of th wealthy during the Roman Empire.在罗马帝国时代，珠宝是深受富人宠爱的宝贝。

08雅思阅读题源精读PAPYRUS-纸莎草系列【1】08雅思阅读题源精读 | PAPYRUS-纸莎草系列【1】雅思阅读Vol.08PAPYRUS前情回顾：之前江鸟大哥更新过一篇比较晦涩难懂的文章：《氟化物系列1》，《氟化物系列2》，单词的生疏会对阅读过程造成很大的阻碍。

这次选了一篇可读性较强的文章进行进一步的精读和精讲。

文章标题：PAPYRUS--Used by the ancient Egyptians to make paper, the papyrus plant has helped to shape the world we live in如果你看到文章标题是一个完全陌生的单词，其实没有必要惊慌。

因为后面会对这个主题词进行解释说明：古希腊人用这种植物制造纸张。

如果对于这方面有一些背景知识，不难猜出：纸莎草第一段的第一句：Libraries and archives are cultural crossroads of knowledge exchange, where the past transmits information to the present, and where the present has the opportunity to inform the future.译文：图书馆和档案馆是知识交换的十字路口，在那里。

现在不仅和过去传递着信息，并且能够预测未来单词：the present: 时间—现在这一句根本没提到主题：纸莎草。

那写第一句话的目的是什么呢？我们中文讲究“虎头豹尾”，意思是开头需要非常强而有力，震撼人心。

但是英文和中文的写作格式不同之处在于：第一段只是在介绍背景知识。

介绍背景知识的方法主要有4种。

其中非常重要的是：追溯过去不难看出，这篇文章的第一段就是追溯过去这是一种常见的做法。

再举一个例子The history of human civilization is entwined with the historyof the ways we have learned to manipulate water resources.译文：人类文明的历史和人类学会利用水资源的历史交织在一起，息息相关。

雅思（阅读）历年真题试卷汇编7（题后含答案及解析）雅思（阅读）历年真题试卷汇编7(题后含答案及解析) 题型有：1.New Zealand SeaweedCall us not weeds; we are flowers of the sea.Section ASeaweed is a particularly nutritious food, which absorbs and concentrates traces of a wide variety of minerals necessary to the body’s health. Many elements may occur in seaweed—aluminium, barium, calcium, chlorine, copper, iodine and iron, to name but a few—traces normally produced by erosion and carried to the seaweed beds by river and sea currents. Seaweeds are also rich in vitamins: indeed, Eskimos obtain a high proportion of their bodily requirements of vitamin C from the seaweeds they eat.The nutritive value of seaweed has long been recognized. For instance, there is a remarkably low incidence of goiter amongst the Japanese, and for that matter, amongst our own Maori people, who have always eaten seaweeds, and this may well be attributed to the high iodine content of this food. Research into old Maori eating customs shows that jellies were made using seaweeds, fresh fruit and nuts, fuchsia and tutu berries, cape gooseberries, and many other fruits which either grew here naturally or were sown from seeds brought by settlers and explorers.Section BNew Zealand lays claim to approximately 700 species of seaweed, some of which have no representation outside this country. Of several species grown worldwide, New Zealand also has a particularly large share. For example, it is estimated that New Zealand has some 30 species of Gigartina, a close relative of carrageen or Irish moss. These are often referred to as the New Zealand carrageens. The gel-forming substance called agar which can be extracted from this species gives them great commercial application in seameal, from which seamealcustard is made, and in cough mixtures, confectionery, cosmetics, the canning, paint and leather industries, the manufacture of duplicating pads, and in toothpastes. In fact, during World War II, New Zealand Gigartina were sent to Australia to be used in toothpaste.Section CYet although New Zealand has so much of the commercially profitable red seaweeds, several of which are a source of agar(Pterocladia, Gelidium, Chondrus, Gigartina), before 1940 relatively little use was made of them. New Zealand used to import the Northern Hemisphere Irish moss(Chondrus crispus)from England and ready-made agar from Japan. Although distribution of the Gigartina is confined to certain areas according to species, it is only on the east coast of the North Island that its occurrence is rare. And even then, the east coast, and the area around Hokiangna, have a considerable supply of the two species of Pterocladia from which agar is also available. Happily, New Zealand-made agar is now obtainable in health food shops. Section D Seaweeds are divided into three classes determined by colour—red, brown and green—and each tends to live in a specific location. However, except for the unmistakable sea lettuce(Ulva), few are totally one colour; and especially when dry, some species can change colour quite significantly—a brown one may turn quite black, or a red one appear black, brown, pink or purple. Identification is nevertheless facilitated by the。

【最新】雅思阅读背景知识：植物学-word范文本文部分内容来自网络整理，本司不为其真实性负责，如有异议或侵权请及时联系，本司将立即删除！== 本文为word格式，下载后可方便编辑和修改！ ==雅思阅读背景知识：植物学植物学是生物学的分支学科。

主要研究植物的结构、生长、繁殖、新陈代谢、发展、化学特征、疾病及进化等等。

研究可以从多个角度切入，通过研究植物的细胞器、细胞、组织、器官、个体、种群，可以了解到其分子、基因和生物化学各方面的信息。

人类早期对于植物的研究主要出于辨别植物能否食用，能否入药及是否有毒，这也使植物学成为最老的一门学科之一。

当今植物学家研究了超过550000种植物，目的在于开发、利用、改造和保护植物资源，让植物为人类提供更多的食物、纤维、药物、建筑材料等。

植物的基本结构和其他话题一样，考生对于植物学的了解并不需要多么专业，但朗阁海外考试研究中心的专家提醒各位考生，至少要了解一些和植物相关的基本词汇才能理解文章所要表达的内容。

以一棵树为例，其组成部分主要包括了树干、树皮、根、树枝、细枝、嫩芽，幼苗、树叶、叶柄等。

植物的花包括了花苞、花瓣、花蜜、花粉、雌蕊、雄蕊等。

植物的果实包括了果皮、果肉、种子等，有的种子外部会包裹坚硬的壳，以保护种子不受伤害。

植物的光和作用不论对于植物还是人类乃至整个地球来说，光和作用都是非常重要的过程。

简单来说，光和作用就是绿色植物利用光能将其所吸收的二氧化碳和水转化为有机物，并释放出氧气的过程。

存在于叶子中的叶绿素和一些酶在光合作用中起到了举足轻重的作用。

在这个过程中，植物为人类消耗了我们生产、生活中所排放的二氧化碳气体，也就是通常意义上的温室气体。

植物释放的氧气是人类生存必不可少的。

同时，植物生产储存的有机物又为动物提供能量来源，因此植物被称为食物链的生产者。
