雅思劍12閱讀真題Test5Passage1原文及題目

　　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.

　　雅思劍12閱讀Test5 Passage1答案解析

　　Test 5 Passage 1

　　Question 1

　　答案：NOT GIVEN

　　關鍵詞：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….”

　　解題思路：原文只提到軟木橡樹的樹皮能長到20厘米的厚度，并未提到它的樹皮是否是所有樹中最厚的。

　　Question 2

　　答案：FALSE

　　關鍵詞：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”

　　解題思路：原文提到這種樹有著特別的細胞結(jié)構(gòu)，而且如今的技術(shù)還未能成功復制這種結(jié)構(gòu)。

　　Question 13

　　答案：desertification

　　關鍵詞：cork forests

　　定位原文：最后一段倒數(shù)第二句：“Moreover, cork forests are a resource which support local biodiversity, and prevent desertification in the regions where they are planted.”

　　解題思路：題目中的stop對應文中的prevent，文中提到軟木橡森林能夠預防種植區(qū)域出現(xiàn)沙漠化。

　　雅思閱讀備考資料怎么選

　　雅思閱讀備考中，考生可以參考一些專業(yè)的資料，指導我們更有效的進行備考。面對市面上這么多資料，很多考生表示不知道怎么選擇。接下來小編為大家推薦一些雅思閱讀備考資料，希望能幫助各位考生有效備考雅思閱讀。

　　一、雅思閱讀資料的選擇

　　考生在選擇雅思備考資料時，可以根據(jù)三個標準來選擇，即閱讀基礎類，技巧類以及練習類。考生哪一方面不足就要適當選擇哪一方面的備考資料。

　　除了這些與雅思閱讀考試非常相關的備考資料之外，考生還可以適當接觸一些比較原汁原味的英語文章，比如BBC，國家地理雜志，新科學家雜志等等。當然，考生也要根據(jù)自身的實際水平去選擇。如BBC，國家地理雜志的文章內(nèi)容豐富，形式和結(jié)構(gòu)比較活潑并充滿視覺沖擊力，更適合剛接觸G類雅思閱讀考試且英語基礎較薄弱的考生。

　　二、雅思閱讀技巧如何提高?

　　雅思閱讀技能培養(yǎng)主要強調(diào)的是閱讀理解技能的培養(yǎng)?？忌粌H要注重閱讀，更要注重理解，也就是說在閱讀的基礎上加之對文章內(nèi)容的理解，這樣才能快而準的解題。

　　想要達到此目的，考生就要制定雅思閱讀理解能力提升計劃，從背景知識，詞匯，語法，泛讀，精讀四方面著手準備。背景知識對理解文明起到舉足輕重的作用，比如如果對英國政黨制度沒有一定了解的話，經(jīng)濟學人上的關于英國工黨選舉的那些事就很有可能看不懂，盡管知道每個單詞每個短語的意思。詞匯是閱讀理解的基石，語法對閱讀理解的準確率有很大的影響，比如長難句理解不透徹的話，理解起來就會吃力，泛讀和精讀是提升閱讀速度和質(zhì)量的保證。總之，不管是哪一個方面，考生都要認真學習，補充能量，這樣才會逐步提升閱讀理解能力，拿下高分。

　　雅思閱讀怎么備考效果更好

　　雅思閱讀考試題型比較多，而且文章信息量比較大，對于考生來說時間比較緊迫。那么雅思閱讀怎么備考效果更好呢?接下來小編為大家分享一些雅思閱讀備考經(jīng)驗，希望能幫助到各位考生在備考中更有效的學習。

　　雅思閱讀中題目的類型是影響雅思閱讀分數(shù)一個明顯因素，尤其是匹配題更是其中的重中之重，主要考察信息查找定位和同義詞理解，強調(diào)在原文中查找細節(jié)信息的能力。而考生無法準確提高匹配題的精準度也是無法獲得高分的重要原因之一。

　　對于第一次備考雅思閱讀的考生來說，往往都找不到正確的復習方法，埋頭刷了很多題，試了網(wǎng)上流傳的各種亂七八糟的方法，分數(shù)卻始終沒有實質(zhì)性的進展，因為使用了錯誤的復習備考方法。

　　雅思閱讀基本要求是這樣的，一是單詞和語法雅思是個沒有大綱的考試，很多人會很擔心，是不是需要大量的詞匯。作為一個純粹的語言測試，雅思考試無非要保證你在國外可以干兩件事情，第一個就是正常的人際交往，你要跟同學老師交流、跟周圍的工作人員交流，這個時候沒有一定的詞匯量是不行的。

　　其次，雖然是閱讀一些科普性的或者是教科書式的材料，基本詞匯量還是要有的，尤其是學術(shù)詞匯，這個比例不是特別高。大家在網(wǎng)上可以找到一個列表叫做ACADEMICWORD LIST，這個列表收集了很多學術(shù)論文、教材當中頻繁出現(xiàn)的單詞，如果你把這個列表里的詞會背的很熟，你在雅思閱讀當中所看到的詞匯也不會特別陌生。

　　關于語法，這個存在比較大的誤區(qū)，很多同學從小到大被中國的英語考試折騰的煩不勝煩，大量的詞義辨析和對語法書中細枝末節(jié)知識點的考查，已經(jīng)讓大家到了談語法色變的地步。但是在雅思閱讀當中對語法的考察主要是識別，也就是考察你在面對一個結(jié)構(gòu)復雜的長句的時候能否快速有效地抓出句子的主干成分，進而繞過語法障礙理解句意的能力。
