雅思剑12阅读真题Test5Passage1原文及题目
READING PASSAGE 1
You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.
Cork
Cork - the thick bark of the cork oak tree (Quercus suber) - is a remarkable material. It is tough, elastic, buoyant, and fire-resistant, and suitable for a wide range of purposes. It has also been used for millennia: the ancient Egyptians sealed their sarcophagi (stone coffins) with cork, while the ancient Greeks and Romans used it for anything from beehives to sandals.
And the cork oak itself is an extraordinary tree. Its bark grows up to 20 cm in thickness, insulating the tree like a coat wrapped around the trunk and branches and keeping the inside at a constant 20℃ all year round. Developed most probably as a defence against forest fires, the bark of the cork oak has a particular cellular structure - with about 40 million cells per cubic centimetre - that technology has never succeeded in replicating. The ceils are filled with air, which is why cork is so buoyant.
It also has an elasticity that means you can squash it and watch it spring back to its original size and shape when you release the pressure.
Cork oaks grow in a number of Mediterranean countries, including Portugal, Spain, Italy, Greece and Morocco. They flourish in warm, sunny climates where there is a minimum of 400 millimetres of rain per year, and not more than 800 millimetres. Like grape vines, the trees thrive in poor soil, putting down deep roots in search of moisture and nutrients. Southern Portugal’s Alentejo region meets all of these requirements, which explains why, by the early 20th century, this region had become the world’s largest producer of cork, and why today it accounts for roughly half of all cork production around the world.
Most cork forests are family-owned. Many of these family businesses, and indeed many of the trees themselves, are around 200 years old. Cork production is, above all, an exercise in patience. From the planting of a cork sapling to the first harvest takes 25 years, and a gap of approximately a decade must separate harvests from an individual tree. And for top-quality cork, it’s necessary to wait a further 15 or 20 years. You even have to wait for the right kind of summer’s day to harvest cork. If the bark is stripped on a day when it’s too cold - or when the air is damp - the tree will be damaged.
Cork harvesting is a very specialised profession. No mechanical means of stripping cork bark has been invented, so the job is done by teams of highly skilled workers. First, they make vertical cuts down the bark using small sharp axes, then lever it away in pieces as large as they can manage. The most skilful cork- strippers prise away a semi-circular husk that runs the length of the trunk from just above ground level to the first branches. It is then dried on the ground for about four months, before being taken to factories, where it is boiled to kill any insects that might remain in the cork. Over 60% of cork then goes on to be made into traditional bottle stoppers, with most of the remainder being used in the construction trade. Corkboard and cork tiles are ideal for thermal and acoustic insulation, while granules of cork are used in the manufacture of concrete.
Recent years have seen the end of the virtual monopoly of cork as the material for bottle stoppers, due to concerns about the effect it may have on the contents of the bottle. This is caused by a chemical compound called 2,4,6-trichloroanisole (TCA), which forms through the interaction of plant phenols, chlorine and mould. The tiniest concentrations - as little as three or four parts to a trillion - can spoil the taste of the product contained in the bottle. The result has been a gradual yet steady move first towards plastic stoppers and, more recently, to aluminium screw caps. These substitutes are cheaper to manufacture and, in the case of screw caps, more convenient for the user.
The classic cork stopper does have several advantages, however. Firstly, its traditional image is more in keeping with that of the type of high quality goods with which it has long been associated. Secondly - and very importantly - cork is a sustainable product that can be recycled without difficulty. Moreover, cork forests are a resource which support local biodiversity, and prevent desertification in the regions where they are planted. So, given the current concerns about environmental issues, the future of this ancient material once again looks promising.

雅思剑12阅读Test5 Passage1答案解析
Test 5 Passage 1
Question 1
答案：NOT GIVEN
关键词：cork oak; thickest bark
定位原文：第二段第二句“Its bark grows up to 20cm in thickness, insulating the tree….”
解题思路：原文只提到软木橡树的树皮能长到20厘米的厚度，并未提到它的树皮是否是所有树中最厚的。
Question 2
答案：FALSE
关键词：a synthetic cork; same cellular structure
定位原文：第二段第三句“… the bark of the cork oak has a particular cellular structure… that technology has never succeeded in replicating”
解题思路：原文提到这种树有着特别的细胞结构，而且如今的技术还未能成功复制这种结构。
Question 13
答案：desertification
关键词：cork forests
定位原文：最后一段倒数第二句：“Moreover, cork forests are a resource which support local biodiversity, and prevent desertification in the regions where they are planted.”
解题思路：题目中的stop对应文中的prevent，文中提到软木橡森林能够预防种植区域出现沙漠化。
雅思阅读备考资料怎么选
雅思阅读备考中，考生可以参考一些专业的资料，指导我们更有效的进行备考。面对市面上这么多资料，很多考生表示不知道怎么选择。接下来小编为大家推荐一些雅思阅读备考资料，希望能帮助各位考生有效备考雅思阅读。
一、雅思阅读资料的选择
考生在选择雅思备考资料时，可以根据三个标准来选择，即阅读基础类，技巧类以及练习类。考生哪一方面不足就要适当选择哪一方面的备考资料。
除了这些与雅思阅读考试非常相关的备考资料之外，考生还可以适当接触一些比较原汁原味的英语文章，比如BBC，国家地理杂志，新科学家杂志等等。当然，考生也要根据自身的实际水平去选择。如BBC，国家地理杂志的文章内容丰富，形式和结构比较活泼并充满视觉冲击力，更适合刚接触G类雅思阅读考试且英语基础较薄弱的考生。
二、雅思阅读技巧如何提高?
雅思阅读技能培养主要强调的是阅读理解技能的培养。考生不仅要注重阅读，更要注重理解，也就是说在阅读的基础上加之对文章内容的理解，这样才能快而准的解题。
想要达到此目的，考生就要制定雅思阅读理解能力提升计划，从背景知识，词汇，语法，泛读，精读四方面着手准备。背景知识对理解文明起到举足轻重的作用，比如如果对英国政党制度没有一定了解的话，经济学人上的关于英国工党选举的那些事就很有可能看不懂，尽管知道每个单词每个短语的意思。词汇是阅读理解的基石，语法对阅读理解的准确率有很大的影响，比如长难句理解不透彻的话，理解起来就会吃力，泛读和精读是提升阅读速度和质量的保证。总之，不管是哪一个方面，考生都要认真学习，补充能量，这样才会逐步提升阅读理解能力，拿下高分。
雅思阅读怎么备考效果更好
雅思阅读考试题型比较多，而且文章信息量比较大，对于考生来说时间比较紧迫。那么雅思阅读怎么备考效果更好呢?接下来小编为大家分享一些雅思阅读备考经验，希望能帮助到各位考生在备考中更有效的学习。
雅思阅读中题目的类型是影响雅思阅读分数一个明显因素，尤其是匹配题更是其中的重中之重，主要考察信息查找定位和同义词理解，强调在原文中查找细节信息的能力。而考生无法准确提高匹配题的精准度也是无法获得高分的重要原因之一。
对于第一次备考雅思阅读的考生来说，往往都找不到正确的复习方法，埋头刷了很多题，试了网上流传的各种乱七八糟的方法，分数却始终没有实质性的进展，因为使用了错误的复习备考方法。
雅思阅读基本要求是这样的，一是单词和语法雅思是个没有大纲的考试，很多人会很担心，是不是需要大量的词汇。作为一个纯粹的语言测试，雅思考试无非要保证你在国外可以干两件事情，第一个就是正常的人际交往，你要跟同学老师交流、跟周围的工作人员交流，这个时候没有一定的词汇量是不行的。
其次，虽然是阅读一些科普性的或者是教科书式的材料，基本词汇量还是要有的，尤其是学术词汇，这个比例不是特别高。大家在网上可以找到一个列表叫做ACADEMICWORD LIST，这个列表收集了很多学术论文、教材当中频繁出现的单词，如果你把这个列表里的词会背的很熟，你在雅思阅读当中所看到的词汇也不会特别陌生。
关于语法，这个存在比较大的误区，很多同学从小到大被中国的英语考试折腾的烦不胜烦，大量的词义辨析和对语法书中细枝末节知识点的考查，已经让大家到了谈语法色变的地步。但是在雅思阅读当中对语法的考察主要是识别，也就是考察你在面对一个结构复杂的长句的时候能否快速有效地抓出句子的主干成分，进而绕过语法障碍理解句意的能力。
