雅思阅读动植物类真题：The Pearl

The Pearl

Throughout history, pearls have held a unique presence within the wealthy

and powerful. For instance, the pearl was the favored gem of the wealthy

ring the Roman Empire. This gift from the sea had been brought back from

the 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 1612

drawn up by the Duke of Saxony prohibited the wearing of pearls by nobility,

professors, doctors or their wives in an effort to further distinguish royal

appearance. American Indians also used freshwater pearls from the Mississippi

River as decorations and jewelry.

There are essentially three types of pearls: natural, cultured and imitation. A

natural pearl (often called an Oriental pearl) forms when an irritant, such as

a piece of sand, works its way into a particular species of oyster, mussel, or

clam. 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 lustrous

pearl is formed.

The only difference natural pearls and cultured pearls is that the irritant is

a surgically implanted bead or piece of shell called Mother of Pearl. Often,

these shells are ground oyster shells that are worth

significant amounts of money in their own right as

irritant-catalysts for quality pearls. The resulting

core is, much larger than in a natural pearl. Yet,

as long as there are enough layers of nacre (the

secreted fluid covering the irritant) to result in a

beautiful, gem-quality pearl, the size of the nucleus

is of no consequence to beauty or rability.

Pearls can come from either salt or freshwater sources. Typically, saltwater

pearls tend to be higher quality, although there are several types of freshwater

pearls that are considered high in quality as well. Freshwater pearls tend to

be very irregular in shape, with a puffed rice appearance the most prevalent.

Nevertheless, it is each indivial pearls merits that determines value more

than the source of the pearl. Saltwater pearl oysters are usually cultivated in

protected lagoons or volcanic atolls. However, most freshwater cultured pearls

sold today come from China. Cultured pearls are the response of the shell to a

tissue implant. A tiny piece of mantle tissue from a donor shell is transplanted

into a recipient shell. This graft will form a pearl sac and the tissue will

precipitate calcium carbonate into this pocket. There are a number of options

for procing cultured pearls: use freshwater or seawater shells, transplant

the 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.

Regardless of the method used to acquire a pearl, the process usually takes

several 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 is

in 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, or

the oyster may simply die from disease or

countless other complications. By the end

of a 5 t0 10 year cycle, only 50% of the

oysters will have survived. And of the pearls

proced, only approximately 5% are of

substantial quality for top jewelry makers.

From the outset, a pearl fanner can figure

on spending over $100 for every oyster

that is farmed, of which many will proce

nothing or die.

Imitation pearls are a different story

altogether. In most cases, a glass bead is

dipped into a solution made from fish

scales. This coating is thin and may

eventually wear off. One can usually

tell an imitation by biting on it. Fake

pearls glide across your teeth, while the

layers of nacre on real pearls feel gritty.

The Island of Mallorca (in Spain) is known for its imitation pearl instry.

Quality natural pearls are very rare jewels. The actual value of a natural pearl

is determined in the same way as it would be for other “precious” gems.

The valuation factors include size, shape, color, quality of surface, orient

and 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 perform

an x-ray of the pearl. If the x-ray reveals a nucleus, the pearl is likely a beadnucleated

saltwater pearl. If no nucleus is present, but irregular and small dark

inner spots indicating a cavity are visible, combined with concentric rings of

organic substance, the pearl is likely a cultured freshwater. Cultured freshwater

pearls can often be confused for natural pearls which present as homogeneous

pictures which continuously darken toward the surface of the pearl. Natural

pearls will often show larger cavities where organic matter has dried out and

decomposed. Although imitation pearls look the part, they do not have the

same 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 sells

for about $1,500, while a super- high quality strand sells for about $4,500. Size

on the other hand, has to do with the age of the oyster that created the pearl (the

more mature oysters proce larger pearls) and the location in which the pearl

was cultured. The South Sea waters of Australia tend to proce the larger

pearls; probably because the water along the coast line is supplied with rich

nutrients from the ocean floor. Also, the type of mussel common to the area

seems to possess a predilection for procing comparatively large pearls.

Historically, the world’s best pearls came from the Persian Gulf, especially

around 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 of

Gulf pearls probably derived from the unique mixture of sweet and salt water

around the island. Unfortunately, the natural pearl instry of the Persian Gulf

ended abruptly in the early 1930’s with the discovery of large deposits of

oil. Those who once dove for pearls sought prosperity in the economic boom

ushered in by the oil instry. The water pollution resulting from spilled oil

and indiscriminate over-fishing of oysters essentially ruined the once pristine

pearl procing waters of the Gulf. Today, pearl diving is practiced only as

a hobby. Still, Bahrain remains one of the foremost trading centers for high

quality pearls. In fact, cultured pearls are banned from the Bahrain pearl

market, in an effort to preserve the location’s heritage. Nowadays, the largest

stock of natural pearls probably resides in India. Ironically, much of India’s

stock of natural pearls came originally from Bahrain. Unlike Bahrain, which

has essentially lost its pearl resource, traditional pearl fishing is still practiced

on a small scale in India.

雅思阅读技巧之词汇+ 总结

雅思阅读技巧锦囊一：英语词库

所谓英语词库是英语对英语的词库而非是英语对汉语的词库。每个烤鸭都清楚雅思是国际性考试而非中国性质考试，单词背其中文意思在考试过程中是无效的，题目和文章都没有中文的出现。雅思阅读就是在全文中的找答案，可是你所用定位的词很多时候不会老老实实的坐在原文里等着你，这就需要你具备英语同义词的能力。

比如剑桥6的67页的list of headings 的 key point 2 的首句中managers should ensure that all employees have specific goals and receive comments on how well they are doing in those goals. 与之相对应的答案是establish targets and give feedback 同意词组为：have specific goals等于establish targets，receive comments on how well they are doing in those goals等于give feedback。

雅思阅读技巧锦囊二：ability to paraphrase

Paraphrase意思是用英文的句子或者段落来解释其英文的句子或者段落。对于外语系的孩子来讲这种能力的考试是家常便饭，也就造就了他们的理解能力比非外语系的同学们好很多。这种能力在雅思阅读考试中也是司空见惯的。

例如：剑桥6的43页的判断题10. Cities with high level of bicycles usage can be efficient even when public transport is only averagely good. 很多孩子看见only习惯性判为NO。因为太绝对了。实则不然，答案为YES。对应于原文中two most ‘bicycle friend’ cities considered—Amsterdam and Copenhagen—were very efficient, even though their public transport systems were ‘ reasonable but special.

切记：高分的取得不只是靠技巧，阅读能力的提升非常的重要

雅思阅读必备高分三技能

技能一：拥有扎实的词汇语法基础及背景知识

这里强调的其实是英文基础的重要性。考生想要在考试过程中游刃有余，没有一定的词汇量基本是没有办法达成的。当然我们在考试中可以通过上下文，转折词等等猜测生词的意思。但是，一旦生词量超过一定比例，势必会影响考生的理解。说到理解，在雅思考试中碰到长难句是常有的事情。那么扎实的语法基础也是考生正确理解文章意义的一个重要的必备素质。

除去扎实的词汇语法基础之外，丰富的背景知识也是一名高分考生所必须的。雅思阅读考试人文社科类和自然科学类当中有众多小分支话题，涉及天文、地理、生物、地质、语言学、发展史等等众多领域。为了保证考试时的阅读效率及答题的正确性，考生需要在平时多多查阅相关资料，了解各类文章背景。

技能二：熟悉题型的做题思路和技巧和出题角度

雅思阅读考试的题型多种多样，有细节题，有主旨题，有考察整体理解的题型，也有考察辨别信息能力的题型。

因此，建议想要取得高分的学员，在掌握每种题型的解题技巧的同时，还需要研究的是考试的出题角度，仔细研究各种题型考察的是何种能力。然后有针对性的去锻炼这方面的能力。14年的雅思阅读考试中，所占比重最大的几类题型为细节配对题、是非无判断题、选择题。之前常考的 List of headings对在去年的考试中所占比例并不大。14年几乎每场考试都有细节配对题出现，那么其实可以反映出雅思考试更加注重考生的细节定位能力以及对于材料的理解能力。

技能三：充分到位的精读和模拟训练是必不可少的

精读是提高分数的唯一法宝。精读的方法是：

用一小时完整的做一个Test三篇文章，然后一篇文章一篇文章的开始精读。

查出每篇文章的所有生词，并要求认知。接着分析文章所有的长难句，翻译整篇文章。

把所有题的出题点在文章里标出来。我们要非常清楚对是为什么对，错是为什么错。精读可以提高同学们的词汇、长难句分析能力以及对整篇文章做题思路的理解。

模拟训练可以提高考生两方面的能力：一是考试答题顺序的安排。二是考试时间的合理分配。

首先是答题顺序的安排。考生并不用完全按照考试文章的顺序来答题。完全可以通过对于标题的浏览来确定文章大意。然后根据自己的熟悉程度来选择文章的先后顺序。

另外，在确定了文章的先后顺序之后，题目的先后顺序其实也是需要进行合理安排的。比如14年很流行的段落细节配对题，虽然经常出现在文章很靠前的位置，但是，无论什么样的位置出现，这种题型都应该放在最后来解决。除了答题顺序之外，考试时间的精确掌控也是考生是否能够取得高分的一个重要因素。雅思阅读考试是个精泛读结合过程，不是所有的文字都需要进行精读的，恰恰那些基础很好有能力有机会考到高分的考生，往往会犯全篇通读的错误，导致最后答题时间不够，没能完成所有的题目而不能取得满意的成绩。

保存并继续

另外要提醒考生注意的是，在平常的模拟考试中就养成是用答题卡的习惯，这样才不至于在考试的时候因为时间不够而出现答题卡不能填写完全的情况。相信很多次的模拟练习之后，考生一定有能力在考试时，用最合理的时间分配进行最佳顺序的答题，最终取得高分成绩。
