雅思阅读动植物类真题及答案:ThePearl

雅思阅读动植物类真题及答案:ThePearl雅思阅读动植物类真题:The PearlThe PearlAThroughout history, pearls have held a unique presence within the wealthyand powerful. For instance, the pearl was the favored gem of the wealthyduring the Roman Empire. This gift from the sea had been brought back fromthe orient by the Roman conquests. Roman women wore pearls to bed sothey could be reminded of their wealth immediately upon waking up. Beforejewelers 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 cureanything from heart disease to epilepsy, with possible aphrodisiac uses as well.Pearls were once considered an e某clusive privilege for royalty.A law in 1612drawn up by the Duke of Sa某ony 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 pearls tend 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 processusually 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 irritant isin 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 beterrifically 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 appro某imately 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 producenothing 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 candetermine whether a pearl is cultured or natural is to have a gem lab performan 某-ray of the pearl. If the 某-ray reveals a nucleus, the pearl is likely a beadnucleatedsaltwater pearl. If no nucleus is present, but irregular and small darkinner 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 diameter sellsfor 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 largerpearls; 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.GHistorically, the world’s best pearls came from the Persian Gulf, especiallyaround what is now Bahrain. The pearls of the Persian Gulf were naturalcreated and collected by breath-hold divers. The secret to thespecial luster ofGulf pearls probably derived from the unique mi某ture of sweet and salt wateraround the island. Unfortunately, the natural pearl industry of the Persian Gulfend ed 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 from spilled 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 pearlmarket, 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, whichhas essentially lost its pearl resource, traditional pearlfishing is still practicedon a small scale in India.雅思阅读真题答案解析——pearl珍珠1 A【原文参考依据-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,珍珠是深受富人喜爱的宝物。

雅思英语阅读练习题及答案

雅思英语阅读练习题及答案:第一篇内容摘要:The failure of a high-profile cholesterol drug has thrown a spotlight on the complicated machinery that regulates cholesterol levels.★Why did a promising heart drug fail?Doomed drug highlights complications of meddling with cholesterol.1. The failure of a high-profile cholesterol drug has thrown a spotlight on the complicated machinery that regulates cholesterol levels. But many researchers remain confident that drugs to boost levels of 'good' cholesterol are still one of the most promising means to combat spiralling heart disease.2. Drug company Pfizer announced on 2 December that it was cancelling all clinical trials of torcetrapib, a drug designed to raise heart-protective high-density lipoproteins (HDLs). In a trial of 15000 patients, a safety board found that more people died or suffered cardiovascular problems after taking the drug plus a cholesterol-lowering statin than those in a control group who took the statin alone.3. The news came as a kick in the teeth to many cardiologists because earlier tests in animals and people suggested it would lower rates of cardiovascular disease. "There have been no red flags to my knowledge," says John Chapman, a specialist in lipoproteins and atherosclerosis at the National Institute for Health and Medical Research (INSERM) in Paris who has also studied torcetrapib. "This cancellation came as a complete shock."4. Torcetrapib is one of the most advanced of a new breed of drugs designed to raise levels of HDLs, which ferry cholesterol out of artery-clogging plaques to the liver for removal from the body. Specifically, torcetrapib blocks a protein called cholesterol ester transfer protein (CETP), which normally transfers the cholesterol from high-density lipoproteins to low density, plaque-promoting ones. Statins, in contrast, mainly work by lowering the 'bad' low-density lipoproteins.Under pressure5. Researchers are now trying to work out why and how the drug backfired, something that will not become clear until the clinical details are released by Pfizer. One hint lies in evidence from earlier trials that it slightly raises blood pressure in some patients. It was thought that this mild problem would be offset by the heart benefits of the drug. But it is possible that it actually proved fatal in some patients who already suffered high blood pressure. If blood pressure is the explanation, it would actually be good news for drug developers because it suggests that the problems are specific to this compound. Other prototype drugs that are being developed to block CETP work in a slightly different way and might not suffer the same downfall.6. But it is also possible that the whole idea of blocking CETP is flawed, says Moti Kashyap, who directs atherosclerosis research at the VA Medical Center in Long Beach, California. When HDLs excrete cholesterol in the liver, they actually rely on LDLs for part of this process. So inhibiting CETP, which prevents the transfer of cholesterol from HDL to LDL, might actually cause an abnormal and irreversibleaccumulation of cholesterol in the body. "You're blocking a physiologic mechanism to eliminate cholesterol and effectively constipating the pathway," says Kashyap.Going up7. Most researchers remain confident that elevating high density lipoproteins levels by one means or another is one of the best routes for helping heart disease patients. But HDLs are complex and not entirely understood. One approved drug, called niacin, is known to both raise HDL and reduce cardiovascular risk but also causes an unpleasant sensation of heat and tingling. Researchers are exploring whether they can bypass this side effect and whether niacin can lower disease risk more than statins alone. Scientists are also working on several other means to bump up high-density lipoproteins by, for example, introducing synthetic HDLs. "The only thing we know is dead in the water is torcetrapib, not the whole idea of raising HDL," says Michael Miller, director of preventive cardiology at the University of Maryland Medical Center, Baltimore.(613 words nature)Questions 1-7This passage has 7 paragraphs 1-7.Choose the correct heading for each paragraph from the list of headings below.

Question 28答案: Latin关键词:Europe/nation state/At first定位原文: 文中第1、5、6段解题思路: 在首段末句,作者提到了 Before that, Latin was regarded as the lingua franca for European intellectuals. 我们隐约可以感觉到拉丁文在学术界的盛行,但这还不足以让我们确定此空就要填Latin一词。
在第五和第六段中,作者提到了学术界流行拉丁文的原因。
其中第六段开头一句提到A second reason for writing in Latin may, perversely, have a concern for secrecy. 这正好就等同题目中28空后面的那句话,所以我们椎测答案应该填写Latin一词。
Question 29答案: doctors关键词: Mathematicians定位原文: 第6段中最后3句解题思路: 题目中告诉我们:有的时候保护个人观点的欲望远远大于与人分享观点的欲望,特别是对于数学家和___。
在这里应该填上一个表示职业的名词。
而第六段中在mathematician 之后,只有一个表示职业的名词,那就是doctors。
故答案应该填 doctors。

雅思阅读真题答案:龙涎香Ambergris为了帮助大家备考雅思的阅读,参考更多真题,下面小编给大家带来雅思阅读真题答案:龙涎香 Ambergris,望喜欢!雅思阅读真题答案:龙涎香 Ambergris文章标题 Ambergris 龙涎香文章大意关于ambergris龙涎香和amber琥珀第一段说ambergris这个东西很久以前就有了,然后说ambergris的用途有 for medicine, spice,用来制作perfume 什么的等等(有题,matching)然后说但是人们不知道它是从哪里来的,再就是说在古代it worth in weight in gold,当然是贵了。
第二段说以前人们一直把ambergris和amber当作一种东西。
但是有个叫Dick的作者写了一本书讲了这两个东西的区别(有题,matching)说ambergris 通常发现在海面或者shore,但是仍然不知道是从哪里来的。
Amber是一种什么东西,与松树pine有关,然后说了amber的一些特性 hard,transparent,等等,用来做装饰品,头饰什么的,同样 very costly。
(有题,matching)第三段说ambergris是与sperm whale的intestine肠子里的消化digest 某种东西有关。
以为intestine会有题,结果没有,提到了马可波罗,好像与这个发现有关(没题,当笑话好了)第四段就是具体describe ambergris的产生过程了。
(summary 题)大意是,sperm whale吃一种东西叫beaks of squalid,肠子就有助消化,但是不能完全消化,就转化成了另一种东西,应该是体内的垃圾。
这种垃圾是soft的,会被sperm whale 呕吐出来 be vomited up。
然后这种东西遇到空气就会变硬 harden,于是就形成了ambergris了,也解释了为什么ambergris总在海面和shore被发现。

雅思英语阅读练习题及答案:第十二篇雅思英语阅读练习题及答案:第十二篇★Next Year Marks the EU's 50th Anniversary of the TreatyA.After a period of introversion and stunned self-disbelief, continental European governments will recover their enthusiasm for pan-European institution-building in 2007. Whether the European public will welcome a return to what voters in two countries had rejected so short a time before is another matter.B.There are several reasons for Europe’s recovering self-confidence. For years European economies had been lagging dismally behind America (to say nothing of Asia), but in 2006 the large continental economies had one of their best years for a decade, briefly outstripping America in terms of growth. Since politics often reacts to economic change with a lag, 2006’s improvement in economic growth will have its impact in 2007, though the recovery may be ebbing by then.C.The coming year also marks a particular point in a political cycle so regular that it almost seems to amount to a natural law. Every four or five years, European countries take a large stride towards further integration by signing a new treaty: the Maastricht treaty in 1992, the Treaty of Amsterdam in 1997, the Treaty of Nice in 2001. And in 2005 they were supposed to ratify a European constitution, laying the ground for yet more integration—until the calm rhythm was rudely shattered by French and Dutch voters. But the political impetus to sign something every four or five years has only been interrupted, not immobilised, by this setback.D.In 2007 the European Union marks the 50th anniversary of another treaty—the Treaty of Rome, its founding charter. Government leaders have already agreed to celebrate itceremoniously, restating their commitment to “ever closer union” and the basic ideals of Europ ean unity. By itself, and in normal circumstances, the EU’s 50th-birthday greeting to itself would be fairly meaningless, a routine expression of European good fellowship. But it does not take a Machiavelli to spot that once governments have signed the declaration (and it seems unlikely anyone would be so uncollegiate as to veto it) they will already be halfway towards committing themselves to a new treaty. All that will be necessary will be to incorporate the 50th-anniversary declaration into a new treaty containing a number of institutional and other reforms extracted from the failed attempt at constitution-building and—hey presto—a new quasi-constitution will be ready.E.According to the German government—which holds the EU’s agenda-setting presidency during the first half of 2007—there will be a new draft of a slimmed-down constitution ready by the middle of the year, perhaps to put to voters, perhaps not. There would then be a couple of years in which it will be discussed, approved by parliaments and, perhaps, put to voters if that is deemed unavoidable. Then, according to bureaucratic planners in Brussels and Berlin, blithely ignoring the possibility of public rejection, the whole thing will be signed, sealed and a new constitution delivered in 2009-10. Europe will be nicely back on schedule. Its four-to-five-year cycle of integration will have missed only one beat.F.The resurrection of the European constitution will be made more likely in 2007 because of what is happening in national capitals. The European Union is not really an autonomous organisation. If it functions, it is because the leaders of the big continental countries want it to, reckoning that an active European policy will help them get done what they want to do in their own countries.G.That did not happen in 2005-06. Defensive, cynical and self-destructive, the leaders of the three largest euro-zone countries—France, Italy and Germany—were stumbling towards their unlamented ends. They saw no reason to pursue any sort of Europeanpolicy and the EU, as a result, barely functioned. But by the middle of 2007 all three will have gone, and this fact alone will transform the European political landscape. H.The upshot is that the politics of the three large continental countries, bureaucratic momentum and the economics of recovery will all be aligned to give a push towards integration in 2007. That does not mean the momentum will be irresistible or even popular. The British government, for one, will almost certainly not want to go with the flow, beginning yet another chapter in the long history of confrontation between Britain and the rest of Europe. More important, the voters will want a say. They rejected the constitution in 2005. It would be foolish to assume they will accept it after 2007 just as a result of an artful bit of tinkering.Questions 1-6Do the following statemets reflect the claims of the writer in Reading Passage 1? Write your answer in Boxes 1-6 on your answer sheet.TRUE if the statemenht reflets the claims of the writer FALSE if the statement contradicts the claims of the writer NOT GIVEN if it is possbile to say what the writer thinks about this1.After years’ introspection and mistrust, continental European governments will resurrect their enthusiasm for more integration in 2007.2. The European consitution was officially approved in 2005 in spite of the oppositon of French and Dutch voters.3. The Treaty of Rome , which is considered as the fundamental charter of the European Union, was signed in 1957.4.It is very unlikely that European countries will sign the declaration at the 50th anniversary of the Treaty of Rome.5.French government will hold the EU’s presidency and lay down the agenda during the first half of 2008.6.For a long time in hisotry, there has been confrontation between Britain and the rest of European countries.Questions 7-10Complet the following sentencces.Choose NO MORE THAN THREE WORDS from Reading Passage 1 for each answer.Write your answer in Boxes 7-10 on your answer sheet.7.
