雅思12剑桥test6阅读解析 剑桥雅思阅读

剑桥雅思阅读

因为剑桥系列一直是考官和雅思考生的桥梁,也注定会是雅思考试的风向标,剑九的出版,丰富了考生的备考资料。
那么,《剑九》中传递了哪样的信息,延续了剑桥家族中哪些不变,又呈现了哪些变化,以及剑九对现在的雅思考试究竟有哪些指导意义?该如何有效而高效的利用起这本真题集,来实现内功与考试高分双增长的目标?
延续阅读经典题型
之前学生中道听途说有很多猜忌,说在留学大潮的当下,雅思考试为了选拔人才,会在2013年有所变革。
纵观《剑九》中收录的四套高水准的剑桥真题,各位考生大可不必慌张,雅思考试在今年,乃至可预见的2014年,这两年题型上应该不会有新题型出现,依然会延续剑桥家族中的经典题型。
雅思官网上把阅读部分题型分成十种,总体上分为五种大题型,和五种小题型。
前者分别是LIST OF HEADINGS 选段意题;MATCHING搭配题;TRUE,FALSE,NOT GIVEN OR YES,NO,NOT GIVEN判断题,MULTIPLE CHOICE选择题 和SUMMARY填空题。
那么五种小题型大部分是大题型SUMMARY的延续,比如填图表,填流程,看图填词,句子填空,和简答题。
大题型不能存在侥幸心里,五个题型都应该将解题思路烂熟于心,以在考场上迅速切换思路,争取速度,力求准确。
《剑九》文章收录最新
《剑四》、《剑五》中的文章主要集中在2001-2003这三年;《剑六》主要来自2004-2005年,《剑七》多数是2006年和2007年这两年,于是《剑八》中收录的文章,主要是考场上2008年考过的文章,部分来自2007年,个别来自2009年,这次《剑九》中收录的文章,比对了以往的考题,主要来自2009年,个别来自2011年和2012年。
其中有两篇文章在考场上考察了不下四次,这次也光荣退休到《剑九》的真题集中:IS THERE ANYBODY OUT THERE? (《搜索外星生物》 来自2002年,2004年6月26日,2007年1月20日,2009年12月19日),和另外一篇 Venus in transit 《金星凌日》来自2007年5月19日,2008年6月21日,2009年2月28日和2012年4月28日)这就印证了我们一贯的猜测,考场上依然有很多旧题在用,有的甚至能用到4次才退休。
所以我们点题班上为学员整理的内容,还是十分有用的。虽然剑九中收录的文章较以往剑桥系列已经为最新的了(多为2009年),但是很多不了解雅思出题动态的同学依然不满足,期待能多出现2012年或2011年的题目。
其实这是并无意义的,在雅思考试中,文章文本只是依托,我们的任务是做题得分。
结合了2012年全年47场考试141篇阅读文章,我们还是能够洞察出这次剑桥大学考试委员会在编篡剑九的时候还是用了心思的,他们侧重了题型的分配,对现在备考有很大的指导作用。
透露题型考察重点
就大题型而言List of headings 题目数量骤降,与2012年全年的7%数字吻合,体现骤降。
Matching题普遍上升,与2012年全年25%的数字,即每次考试近乎10道搭配题,数量一致,其中人名配理论为普通搭配型的重中之重,《剑九》中一共有两道大题是普通型的搭配,通通都是人名配理论。
另外搭配题中的段落配相关信息型飙升(即如下几个信息在原文中哪个自然段有所提及型),请广大考生注意备考侧重。
其它的题型,判断题仍然占有绝对优势,Multiple choice 单多选题, 并无出众表现。SUMMARY 从数量上较以往剑桥系列有所下降,但是结合了它繁衍成的小题型来看一点都不少。
那么小题型中,《剑九》中虽没有出现表格题,但这对我们丝毫没有影响,因为表格题直接套用填空题的方法即可。
不过有意思的是,简答题象一匹黑马冲了出来,其它的剑桥系列都没怎么出题的简答题,在《剑九》中大量出现,有两点发现:
第一,完善了剑桥系列的阅读题型,针对简答题让考生有题可练,有题能练,而且能够通过剑九练透。
第二,让考生意识到,稍微方法不同与SUMMARY的小题型考察数量在增加,除了简答,完成句子中类似普通MATCHING题的比重也有所增加。
这个趋势已经从2013年的头几个月考试中能够显露出来。
如何高效利用《剑九》?
考前两周当真题冲刺用,结合听力部分,完全利用《剑九》当模拟题来考察自己的能力。
建议模考时间设定在周一和周三,周二和周四进行分析,周五查漏补缺,周六亲临考场。
做题顺序建议:按顺序即可:Test1- Test2-Test3-Test4 等级为: 中——难——难——中。解释一下,第一套用中等水平题目验证一下自己复习的是否充分有效,如果不如预期,停下来分析剑桥6,7,8做过的题目。
分析好了以后再回来操作剑九第二套,而后第三套,经历了难度递增之后,最后临考前加强信心,做第四套。
每每做完套题都不要立刻对答案,这样就不可避免的会对着答案往文章里去思考,从而不能达到能力的提高。
应该采取三步走,第一步,先严格计时做,第二步再可放松时间延时做,最后第三步翻着字典做。
三遍都经历之后,才可核对答案,记录下三次的答案是否有出入,找到自己的不足。
延时后能多对几个的,说明语言还不错,可能方法上有漏洞,以至于一卡时间,语言就发挥不出来了。
查字典后能多对上几个的,说明内功不足,这样短时间大体上就可以找到自己的问题。
然后需要静下心来,认真分析。错题对题都需要回原文,定位分析,推敲答案。

雅思阅读熟词多义题解析

英语中纯粹的单义词很少,绝大多数词都是多义词,即一个词项有两个或两个以上的意义。在雅思阅读中,有很多词汇看似很简单,很熟悉,殊不知他有多个意思。把小伙伴们都迷得晕头转向的。今天我来为大家收集整理了雅思阅读熟词多义题解析,希望小伙伴们在雅思考试时能提高警惕,不再犯迷糊!

以下主要就雅思阅读剑桥真题部分的一些存在熟词多义的题目进行解析:

1.drive

C4T1P1:

In other words, they gave no indication of an appreciation of either the range of ways in which rainforests are important or the complex social, economic and political factors which drive the activities which are destroying the rainforests.

这是一个复杂的长难句,一共出现了三处定语从句,一处ways in which, 一处factors which,一处activities which。

drive的主语为连接代词which代指的先行词factors,提取之后变为factors drive the activities, 这里如果将这里作为动词的drive 翻译成驾驶,句子是完成不通顺的,我们从后一处的定语从句中得知,activities指的是破坏雨林的行为,也就是前面的社会经济和政治因素drive了一些破坏雨林的行为,也就是说,这里的drive是导致,迫使的意思。

C6T1P2

选项型SUMMARY

Q24: Manufacturers of computers, for instance, are able to import 24................. from overseas, rather than having to rely on a local supplier.

文章E段 To see how this influences trade, consider the business of making disk drives for computers. Most of the world's disk-drive manufacturing is concentrated in South-east Asia. This is possible only because disk drives, while valuable, are *all and light and so cost little to ship. Computer manufacturers in Japan or Texas will not face hugely bigger freight bills if they import drives from Singapore rather than purchasing them on the domestic market.

通过manufacturers of computers定位到E段。阅读后我们可以知道电脑*商集中在东南亚*和进口disk drives而不是本国市场。如果同学对电脑知识比较了解的话,对于drive在这里的理解应该问题不大。根据一定的语法知识我们看得出这里的disk drives和disk-drive是名词用法,可通过drive的基本含义“驾驶”进一步引申理解,“驾驶磁盘”过渡为“让磁盘启动”,正确的理解含义为:磁盘驱动器。对应到题目提供的选项“B. components”

2.subject

我们知道它由“科目”的意思,词汇稍好的同学还会知道它还有“主语”和“主题”的含义。我们来看下面一题:

C5T1P2

单选题 Q20 The teacher-subjects were told that they were testing whether

A a 450-volt shock was dangerous.

B punishment helps learning.

C the pupils were honest.

D they were suited to teaching.

文章A段 Specifically, Milgram told each volunteer 'teacher-subject' that the experiment was in the noble cause of education, and was designed to test whether or not punishing pupils for their mistakes would have a positive effect on the pupils' ability to learn.

文章这里的'teacher-subject'打了引号,也就是说即便同学你不认识,把它当作一个特殊词符号,不理解不影响做题。不过明显的是,把“科目”“主语”“主题”放这里,都不好理解。在雅思阅读学术实验类的文章中,subject是个高频词汇,作为“实验对象”的含义来使用, 有时会同义替换为volunteer或participant。

C8T1P3

表格填空Q38 The results were then subjected to a 38…………………….

文章:In 1987, results from hundreds of autoganzfeld tests were studied by Honorton in a 'meta-*ysis', a statistical technique for finding the overall results from a set of studies.

通过冠词a我们可以知道此空填名词单数,并且从表格纵轴同行的特殊定位词in 1987,我们找到了定位句。但是定位句中存在冠词a的三处,到底三处后的单词填哪个呢。单词不会,语法来凑,通过题目和文章的主干结构的一致性:A be subjected to B和A be studied By B in C, 由于Honorton是人名且不符合填词规定,顺理成章的'meta-*ysis'成为我们的选填对象。那subject to到底什么意思呢,通过文章,我们可以知道大概是被研究的意思,查了字典我们就了解,正确含义为“受…支配”。

类似的用法单词还有:

1. state n. (美国的)州,状态,*,adj. 国家的,国立的 v.陈述,说明

C8T4P1 判断题Q8 Private schools in Japan are more modern and spacious than state-run lower secondary schools. State-run adj国立的

C7T4P1 第5段 There was a huge initial force- five times larger than the steady state force, Gharib says. State n.状态

2. coin n. 硬币, v. 创造,铸造

C7T1P1 E段 The American zoologist Donald Griffin, who was largely responsible for the discovery of sonar in bats, coined the term 'echolocation' to cover both sonar and radar, whether used by animals or by human instruments. Coin v 创造(first used)

3. spoke v. speak过去式,n 车轮的辐条(C4T1P3)

4. tuitionn. 学费,课程,讲授,教学(C4T1P1)

5. complaint n. 抱怨,*,疾病(C4T2P2)

6. Interest v. 是感兴趣n. 兴趣,利益,利息(C4T3P1)

7. leaves v. leave的动词三单形式 n.叶子(Pl)(C8T4P3)

8. press v. 按压,n. 印刷,新闻工作者,新闻(C5T1P3/C5T4P2)

(pressing adj. 迫切的,急切的 C7T1P2)

Passage1:蝴蝶保护色Copy your neighbour
参考答案:
A THERE’S no animal that symbolises rainforest diversity quite as spectacularly as the tropical butterfly. Anyone lucky enough to see these creatures flitting between patches of sunlight cannot fail to be impressed by the variety of their patterns. But why do they display such colourful exuberance? Until recently, this was almost as pertinent a question as it had been when the 19th-century naturalists, armed only with butterfly nets and insatiable curiosity, battled through the rainforests. These early explorers soon realised that although some of the butterflies’ bright colours are there to attract a mate, others are warning signals. They send out a message to any predators: “Keep off, we’re poisonous.” And because wearing certain patterns affords protection, other species copy them. Biologists use the term “mimicry rings” for these clusters of impostors and their evolutionary idol.
B But here’s the conundrum. “Classical mimicry theory says that only a single ring should be found in any one area,” explains George Beccaloni of the Natural History Museum, London. The idea is that in each locality there should be just the one pattern that best protects its wearers. Predators would quickly learn to avoid it and eventually all mimetic species in a region should converge upon it. “The fact that this is patently not the case has been one of the major problems in mimicry research,” says Beccaloni. In pursuit of a solution to the mystery of mimetic exuberance, Beccaloni set off for one of the megacentres for butterfly diversity, the point where the western edge of the Amazon basin meets the foothills of the Andes in Ecuador. “It’s exceptionally rich, but comparatively well collected, so I pretty much knew what was there, says Beccaloni.” The trick was to work out how all the butterflies were organised and how this related to mimicry.”
C Working at the Jatun Sacha Biological Research Station on the banks of the Rio Napo, Beccaloni focused his attention on a group of butterflies called ithomiines. These distant relatives of Britain’s Camberwell Beauty are abundant throughout Central and South America and the Caribbean. They are famous for their bright colours, toxic bodies and complex mimetic relationships. “They can comprise up to 85 per cent of the individuals in a mimicry ring and their patterns are mimicked not just by butterflies, but by other insects as diverse as damselflies and true bugs,” says Philip DeVries of the Milwaukee Public Museum’s Center for Biodiversity Studies.
D Even though all ithomiines are poisonous, it is in their interests to evolve to look like one another because predators that learn to avoid one species will also avoid others that resemble it. This is known as Miillerian mimicry. Mimicry rings may also contain insects that are not toxic, but gain protection by looking likes a model species that is: an adaptation called Batesian mimicry. So strong is an experienced predator’s avoidance response that even quite inept resemblance gives some protection. “Often there will be a whole series of species that mimic, with varying degrees of verisimilitude, a focal or model species,” says John Turner from the University of Leeds. “The results of these deceptions are some of the most exquisite examples of evolution known to science.” In addition to colour, many mimics copy behaviours and even the flight pattern of their model species.
E But why are there so many different mimicry rings? One idea is that species flying at the same height in the forest canopy evolve to look like one another. “It had been suggested since the 1970s that mimicry complexes were stratified by flight height,” says DeVries. The idea is that wing colour patterns are camouflaged against the different patterns of light and shadow at each level in the canopy, providing a first line of defence against predators.” But the light patterns and wing patterns don’t match very well,” he says. And observations show that the insects do not shift in height as the day progresses and the light patterns change. Worse still, according to DeVries, this theory doesn’t explain why the model species is flying at that particular height in the first place.
F “When I first went out to Ecuador, I didn’t believe the flight height hypothesis and set out to test it,” says Beccaloni.”A few weeks with the collecting net convinced me otherwise. They really flew that way.” What he didn’t accept, however, was the explanation about light patterns. “I thought, if this idea really is true, and I can work out why, it could help explain why there are so many different warning patterns in any one place. Then we might finally understand how they could evolve in such a complex way.” The job was complicated by the sheer diversity of species involved at Jatun Sacha. Not only were there 56 ithomiine butterfly species divided among eight mimicry rings, there were also 69 other insect species, including 34 day-flying moths and a damselfly, all in a 200-hectare study area. Like many entomologists before him, Beccaloni used a large bag-like net to capture his prey. This allowed him to sample the 2.5 metres immediately above the forest floor. Unlike many previous workers, he kept very precise notes on exactly where he caught his specimens.
G The attention to detail paid off. Beccaloni found that the mimicry rings were flying at two quite separate altitudes. “Their use of the forest was quite distinctive,” he recalls. “For example, most members of the clear-winged mimicry ring would fly close to the forest floor, while the majority of the 12 species in the tiger-winged ring fly high up.” Each mimicry ring had its own characteristic flight height.
H However, this being practice rather than theory, things were a bit fuzzy. “They’d spend the majority of their time flying at a certain height. But they’d also spend a *aller proportion of their time flying at other heights,” Beccaloni admits. Species weren’t stacked rigidly like passenger jets waiting to land, but they did appear to have a preferred airspace in the forest. So far, so good, but he still hadn’t explained what causes the various groups of ithomiines and their chromatic consorts to fly in formations at these particular heights.
I Then Beccaloni had a bright idea. “I started looking at the distribution of ithomiine larval food plants within the canopy,” he says. “For each one I’d record the height to which the host plant grew and the height above the ground at which the eggs or larvae were found. Once I got them back to the field station’s lab, it was just a matter of keeping them alive until they pupated and then hatched into *s which I could identify.”

Passage2:CRS企业社会责任感
参考答案:
The moral appeal---arguing that companies have a duty to be good citizens and to “do the right thing” ---is prominent in the goal of Business for Social Responsibility, the leading nonprofit CSR business association in the United States.
A An excellent definition was developed in the 1980s ‘‘ Meeting the needs of the present without compromising the ability of future generations to meet their own needs.” The notion of license to operate derives from the fact that every company needs tacit or explicit permission from governments, communities, and numerous other stakeholders to do business. Finally,reputation is used by many companies to justify CSR initiatives on the grounds that they will improve a company’s image, strengthen its brand,enliven morale, and even raise the Value of its stock.
B To advance CSR, we must root it in a broad understanding of the interrelationship between a corporation and society. To say broadly that business and society need each other might seem like a cliché, but it is also the basic truth that will pull companies out of the muddle that their current corporate-responsibility thinking has created. Successful corporations need a healthy society. Education, health care, and equal opportunity are essential to a productive workforce. Safe products and working conditions not only attract customers but lower the internal costs of accidents. Efficient utilization of land, water, energy, and other natural resources makes business more productive. Good government, the rule of Jaw, and property rights are essential for efficiency and innovation. Any business that pursues its ends at the expense of the society in which it operates will find its success to be illusory and ultimately temporary. At the same time, a health society needs successful companies. No social program can rival the business sector when it comes to creating the jobs, wealth, and innovation that improve standards of living and social conditions over time.
C A company’s impact on society also changes over time, as social standards evolve and science progresses. Asbestos, now understood as a serious health risk, was thought to be safe in the early 1900s, given the scientific knowledge then available. Evidence of its risks gradually mounted for more than 50 years before any company was held liable for the harms it can cause. Many firms that failed to anticipate the consequences of this evolving body of research have been bankrupt by the results. No longer can companies be content to monitor only the obvious social impacts of today. Without a careful process for identifying evolving social effects of tomorrow, firms may risk their very survival.
D No business can solve all of society’s problems or bear the cost of doing so. Instead, each company must select issues that intersect with its particular business. Corporations are not responsible for all the world's problems, nor do they have the resources to solve them all. Each company can identify the particular set of societal problems that it is best equipped to helpresolve and from which it can gain the greatest competitive benefit. Addressing social issues by creating shared value will lead to self-sustaining solutions that do not depend on private or government subsidies. When a well-run business applies its vast resources, expertise, and management talent to problems that it understands and in which it has a stake, it can have a greater impact on social good than any other institution or philanthropic organization.
E The best corporate citizenship initiatives involve far more than writing a check: they specify clear, measurable goals and track results over time. A good example is GE’s program to adopt underperforming public high schools near several of its major U.S. Facilities. The company contributes between $250, 000 and $1 million over a five-year period to each school and makes in-kind donations as well GE managers and employees take an active role by working with school administrators to assess needs and mentor or tutor students. The graduation rate of these schools almost doubled during this time period. Effective corporate citizenship initiatives such as this one create goodwill and improve relations with local governments and other important constituencies. What’s more, GE’s employees feel great pride in their participation. Their effect is inherently limited though. No matter how beneficial the program is, it remains incidental to the company's business, and the direct effect on GE’s recruiting and retention is modest.
F Microsoft is a good example of a shared-value opportunity arising from investments in context. The shortage of information technology workers is a significant constraint on Microsoft’s growth, currently, there are more than 450,000 unfilled IT positions in the United States alone. Community colleges, representing 45% of all U.S. Undergraduates, could be a major solution. Microsoft recognizes, however, that community colleges face special challenges: IT curricula are not standardized, technology used in classrooms is often outdated, and there are no systematic professional development programs to keep faculty up to date. In addition to contributing money and products, Microsoft sent employee volunteers to colleges to assess needs, contribute to curriculum development, and create faculty development institutes. Note that in this case, volunteers and assigned staff were able to use their core professional skills to address a social need, a far cry from typical volunteer programs. Microsoft has achieved results that have benefited many communities while having a direct-and potentially significant-impact on the company.
G At the heart of any strategy is a unique value proposition: a set of needs a company can meet for its chosen customers that others cannot. The most strategic CSR occurs when a company adds a social dimension to its value proposition, making social impact integral to the overall strategy Consider Whole Foods Market, whose value proposition is to sell organic, natural, and healthy food products to customers who are passionate about food and the environment. Whole Foods’ commitment to natural and environmentally friendly operating practices extends well beyond sourcing. Stores are constructed using a minimum of virgin raw materials. Recently, the company purchased renewable wind energy credits equal to 100% of its electricity use in all of its stores and facilities, the only Fortune 500 Company to offset its electricity consumption entirely. Spoiled produce and biodegradable waste are trucked to regional centers for composting. Whole Foods’ vehicles are being converted to run on biofuels. Even the cleaning products used in its stores are environmentally friendly. And through its philanthropy, the company has created the Animal Compassion Foundation to develop more natural and humane ways of raising farm animals. In short, nearly every aspect of the company’s value chain reinforces the social dimensions of its value proposition, distinguishing Whole Foods from its compe*s.

Passage3:沙漠造雨
参考答案:
A. Sometimes ideas just pop up out of the blue. Or in Charlie Paton’s case, out of the rain. “I was in a bus in Morocco travelling through the desert,” he remembers. “It had been raining and the bus was full of hot, wet people. The windows steamed up and I went to sleep with a towel against the glass. When I woke, the thing was soaking wet. I had to wring it out. And it set me thinking. Why was it so wet?”
B. The answer, of course, was condensation. Back home in London, a physicist friend, Philip Davies, explained that the glass, chilled by the rain outside, had cooled the hot humid air inside the bus below its dew point, causing droplets of water to form on the inside of the window. Intrigued, Paton-a lighting engineer by profession-started rigging up his own equipment. “I made my own solar stills. It occurred to me that you might be able to produce water in this way in the desert, simply by cooling the air. I wondered whether you could make enough to irrigate fields and grow crops.”
C. Today, a decade on, his dream has taken shape as giant greenhouse on a desert island off Abu Dhabi in the Persian Gulf ---the first commercially viable Version of his “seawater greenhouse”. Local scientists, working with Paton under a license from his
company Light Works, are watering the desert and growing vegetables in what is basically a giant dew-making machine that produces fresh water and cool air from sum and seawater. In awarding Paton first prize in a design competition two years ago,
Marco Goldschmied, president of the Royal Institute of British Architects, called it “a truly original idea which has the potential to impact on the lives of millions of people living in coastal water-starved areas around the world.”
seawater greenhouse as developed by Paton has three main both air-condition the greenhouse and provide water for front of the greenhouse faces into the prevailing wind so that hot dry air blows in through a front wall is made of perforated cardboard kept moist by a constant trickle of seawater pumped up from purpose is to cool and moisten the incoming desert cool moist air allows the plants to grow faster. And, crucially, because much less water evaporates from the leaves,the plants need much less moisture to grow than if they were being irrigated in the hot dry desert air outside the greenhouse.
air-conditioning of the interior of the greenhouse is completed by the second feature:the roof. It has two layers:an outer layer of clear polyethylene and an inner coated layer that reflects infrared radiation. This combination ensures that visible light can steam through to the plants, maximizing the rate of plant growth through photosynthesis but at the same time heat from the infrared radiation is trapped in the space between the layer, sand kept away keep the air around the plants cool.
F. At the lack of the greenhouse sits the third elements. This is the main water production ,the air hits a second moist cardboard wall that increases its humidity as it reaches the condenser,which finally collects from the hot humid air the moisture for irrigating the condenser is metal surface kept cool by still more seawater. It is the equivalent of the window on Paton’s Morcoccan s of pure distilled water form on the condenser and flow into a tank for irrigating the crops.
Abu Dhai greenhouse more or less runs ors switch everything on when the sun rises and alter flows of air and seawater through the day in response to changes in temperature, humidity, and windless days,fans ensure a constant flow of air through the greenhouse. “Once it is tuned to the local environment,you don’t need anyone there for it to work” says Paton. “We can run the entire operation off one 13-amp plug, and in the future we could make it entirely independent of the grid, powered from a few solar panels.”
ics point out that construction costs of around $4 a square foot are quite illustration, however, Paton presents that it can cool as efficiently as a 500-kilowatt air conditioner while using less than 3 kilowatts of electricity. Thus the plants need only an eighth of the Volume of water used by those grown conventionally. And so the effective cost of desalinated water in the greenhouse is only a quarter that of water from a standard desalinator, which is good economics. Beside it really suggests an environmentally - friendly way of providing air conditioning on a scale large enough to cool large greenhouses where crops can be grown despite the high outside temperatures.
27-31:YES、NO、YES、NOT GIVEN、 NO
32-36:hot dry air、moist、heat、condenser、pure distill water
37-40:fans、solar panels、construction costs、environmentally-friendly
