2023年雅思阅读考试精选习题及答案(3)
Talc Powder
A Peter Brigg discovers how talc from Luzenac's Trimouns in France find its way into food and agricultural products - from chewing gum to olive oil. High in the French Pyrenees, some 1,700m above sea level, lies Trimouns, a huge deposit of hydrated magnesium silicate - talc to you and me. Talc from Trimouns, and from ten other Luzenac mines across the globe, is used in the manufacture of a vast array of everyday products extending from paper, paint and plaster to co*etics, plastics and car tyres. And of course there is always talc's best known end use: talcum powder for babies1 bottoms. But the true versatility of this remarkable mineral is nowhere better displayed than in its sometimes surprising use in certain niche markets in the food and agriculture industries.
B Take, for example, the chewing gum business. Every year, Talc de Luzenac France - which owns and operates the Trimouns mine and is a member of the international Luzenac Group (art of Rio Tinto minerals) supplies about 6,000 tones of talc to chewing gum manufacturers in Europe. "We've been selling to this sector of the market since the 1960s," says Laurent Fournier, sales manager in Luzenac's Specialties business unit in Toulouse. "Admittedly, in terms of our total annual sales of talc, the amount we supply to chewing gum manufacturers is relatively *all, but we see it as a valuable niche market: one where customers place a premium on securing supplies from a reliable, high quality source. Because of this, long term allegiance to a proven suppler is very much a feature of this sector of die talc market." Switching sources - in the way that you might choose to buy, say, paperclips from Supplier A rather than from Supplier B - is not an easy option for chewing gum manufacturers." Fournier says. "The cost of reformulating is high, so when customers are using a talc grade that works, even if it's expensive, they are understandably reluctant to switch."
C But how is talc actually used in the manufacture of chewing gum? Patrick Delord, an engineer with a degree in agronomics, who has been with Luzenac for 22 years and is now senior market development manager, Agriculture and Food, in Europe, explains that chewing gums has four main components. "The most important of them is the gum base," he says. "It's the gum base that puts the chew into chewing gum. It binds all the ingredients together, creating a soft, *ooth texture. To this the manufacturer then adds sweeteners, softeners and flavourings. Our talc is used as a filler in the gum base. The amount vanes between, say, ten and 35 per cent, depending on the type of gum. Fruit flavoured chewing gum, for example, is slightly acidic and would react with the calcium carbonate that the manufacturer might otherwise use as a filler. Talc, on the other hand, makes an ideal filler because it's non-reactive chemically. In the factory, talc is also used to dust the gum base pellets and to stop the chewing gum sticking during the lamination and packing process," Delord adds.
D The chewing gum business is, however, just one example of talc's use in the food sector. For the past 20 years or so, olive oil processors in Spain have been taking advantage of talc's unique characteristics to help them boost the amount of oil they extract from crushed olives According to Patrick Delord, talc is especially useful for treating what he calls "difficult" olives. After the olives are harvested - preferably early in the morning because their taste is better if they are gathered in the cool of the day they are taken to the processing plant. There they arc crushed and then stirred for 30-45 minutes. In the old days, the resulting paste was passed through an olive press but nowadays it's more common to add water and (K-6IH) the mixture to separate the water and oil from the solid matter The oil and water are then allowed to settle so that the olive oil layer can be )and bottled. “Difficult” olives are those that are more reluctant than the norm to yield up their full oil content. This may be attributable to the particular species of olive, or to its water content and the time of year the olives arc collected - at the beginning and the end of the season their water content is often either too high or too low. These olives are easy to recognize because they produce a lot of extra foam during the stirring process, a consequence of an excess of a fine solid that acts as a natural emulsifier. The oil in this emulsion is lost when the water is disposed of. Not only that, if the waste water is disposed of directly into local fields - often the case in many *aller processing operations - the emulsified oil may take some time to biodegrade and so be harmful to the environment.
E "If you add between a half and two percent of talc by weight during the stirring process, it absorbs the natural emulsifier in the olives and so boosts the amount of oil you can extract," says Delord. "In addition, talc's flat, 'platey' structure helps increase the size of the oil droplets liberated during stirring, which again improves the yield. However, because talc is chemically inert, it doesn't affect the color, taste, appearance or composition of the resulting olive oil."
F If the use of talc in olive oil processing and in chewing gum is long established, new applications in the food and agriculture industries arc also constantly being sought by Luzenac. One such promising new market is fruit crop protection, being pioneered in the US. Just like people, fruit can get sunburned. In fact, in very sunny regions up to 45 per cent of a typical crop can be affected by heat stress and sunburn However, in the case of fruit, it's not so much the ultra violet rays which harm the crop as the high surface temperature that the sun's rays create.
G To combat this, farmers normally use either chemicals or spray a continuous fine canopy of mist above the fruit frees or bushes. The trouble is, this uses a lot of water - normally a precious commodity in hot, sunny areas - and it is therefore expensive. What's more, the ground can quickly become waterlogged. "So our idea was to coat the fruit with talc to protect it from the sun," says Greg Hunter, a marketing specialist who has been with Luzenac for ten years. "But to do this, several technical challenges had first to be overcome. Talc is very hydrophobic: it doesn't like water. So in order to have a viable product we needed a wettable powder - something that would go readily into suspension so that it could be sprayed onto the fruit. It also had to break the surface tension of the cutin (the natural waxy, waterproof layer on the fruit) and of course it had to wash off easily when the fruit was harvested. No-one's going to want an apple that's covered in talc."
H Initial trials in the state of Washington in 2023 showed that when the product was sprayed onto Granny Smith apples, it reduced their surface temperature and lowered the incidence of sunburn by up to 60 per cent. Today the new product, known as Invelop Maximum SPF, is in its second commercial year on the US market. Apple growers are the primary target although Hunter believes grape growers represent another sector with long term potential. He is also hopeful of extending sales to overseas markets such as Australia, South America and southern Europe.

影响阅读拿分的因素

1.词汇

第一个影响雅思阅读分数的因素就是词汇。必须在阅读文章中记忆，每篇文章做完题目，要整理一下单词，然后再运用到阅读其他文章中去，这叫从阅读中来，会阅读中去。效果比较明显。不要盲目地扩充大量单词，要有针对性，针对雅思阅读，要知道雅思阅读常考那些词。这可从广泛接触雅思阅读文章中，对单词有感觉。

2.语法

第二个是语法。阅读中很多题目是在考查语法，都是暗地里考。特别是主观题，还有题目与原文的一些改写，都是建立在语法的基础上的。我们要注意一些关系，比如说对比对照关系，因果关系，因为两事物一旦有了关系，就热闹了，就比较好出题了。

3.逻辑关系

第三个是逻辑关系。雅思有个别难题不光是考查大家的英文水平，同时还在考查大家的逻辑思维能力。有些题目就是在这个环节出了问题，全部单词都认识，就是题做不对。这样的题多是判断题和单选题。

4.文章的背景

第四个是文章的背景。这是影响雅思阅读分数最不明显的因素。雅思阅读文章的背景我们也要熟悉，比如交通能源污染，这是雅思考试永恒的话题。我们必须积累这方面的常识，背景。另外还有建筑，动植物，医疗健康，公司管理，高科技等等。

5.题目的类型

第五个是雅思阅读题目的类型。其实这是影响雅思阅读分数的最明显的因素。十多种题目类型可以进行以下划分，实力题与技巧题，必考题与选考题，主观题与客观题。这样的话，考生就比较容易把握题目类型了，而且可以根据自己的实际水平，调整做题的先后顺序。比如说，一个实力稍微弱点的学生，就要先去找填图填表，匹配，简答这类的题目做。而像判断题能做就做，如果有的连题干都看不懂，那只能根据一般规律去做，也就是蒙。这是没有办法的办法。但总比你在那浪费上十多分钟强，但也不能空着。

雅思阅读题型介绍

多重选择题型 （maltiple-choice tasks）；

IELTS阅读测试中多重选择题型与toefl测试中的多重选择题型虽然类似，但实质上差别很大。ielt阅读测试中的多重选择题型更多侧重于对文章的理解，而非强调语法、词法的运用。

完成句子题型 （sentence completion tasks）；

这种题目比较花时间，需要考生根据选项在文章仔细的寻找相关的信息，这也是考察考生筛选信息和提取信息的能力。题目会给出句子的一部分内容，没有给出的部分便要求考生在文章中去找，或者给你选项让你选一个。

摘要（summary）、填空题型 （gapfill）；

填空题通常有两种形式：一种是根据文章内容选择词或短语填空，一般是为阅读文章的缩写内容进行填空；另一种则无参考文章，只是一篇短文。第1种题型相对第二种题型较难，所花费时间较多，因为要将两篇文章进行语句、词语的比较。不过这种缩写形式对于理解所给阅读文章有所帮助。第二种形式是利用所给单词或短语进行填空。

配对题（matching）；

这种题型也是考察考生的信息筛选能力。这种题型较为普遍，配对的范围主要包括新产品的发明家、发明时间，事件和事件的发展经过，事件发生的原因和结果，文章内容中概念的解释和标志性事物及其所处的年代等等。

完成图表、示意图题型（table、chart or diagram completion）；

这种题目便是要求考生将图标的信息补全。在雅思阅读中，会出现很多的图表和示意图，这些图表中的文字内容不多，但是问题的答案都包含在图表之中，需要考生自己去填补。

回答问题（short-answer question tasks）；

回答问题是根据所给文章或图表回答问题。这种题目是考察考生对信息的筛选和提取能力，比如在IELTS阅读测试中通常是用下列单词提问：. what、which、when、where、who、whose、whom、why、 how 等。除了利用上述单词进行提问外，有时会在答题指引中将所提问题列出。

辨别正误题型（True / false /not given）；

该题型还涉及到：（not given / not mentioned）没有提到，有时还会出现下列提法accurat / inaccurat 准确/不准确；supported / contradicted 一致/不一致。correct / incorrect 正确与不正确。辨别正误题型属于难度较大的题型。通常在阅读测试中的第三或 第四部分出现。

paragraph headings（段落标题）较频繁的题型之一；

一般来说有10个左右的标题选项会给出在阅读文章的后面，其中会包含一到两个段落和其标题的例子。这种题目要求考生对给出的段落在文章内容中找出与其相匹配的段落标题，虽然题目给出的标题会应用于多个段落，但是在正式的考试中，一个选项只能适用于一个段落。

2023年雅思阅读真题全面解析及答案(3)
Can Scientists tell us: What happiness is?
A
Economists accept that if people describe themselves as happy, then they are happy. However, psychologists differentiate between levels of happiness. The most immediate type involves a feeling; pleasure or joy. But sometimes happiness is a judgment that life is satisfying, and does not imply an emotional state. Esteemed psychologist Martin Seligman has spearheaded an effort to study the science of happiness. The bad news is that we're not wired to be happy. The good news is that we can do something about it. Since its origins in a Leipzig laboratory 130 years ago, psychology has had little to say about goodness and contentment. Mostly psychologists have concerned themselves with weakness and misery. There are libraries full of theories about why we get sad, worried, and angry. It hasn't been respectable science to study what happens when lives go well. Positive experiences, such as joy, kindness, altrui* and heroi*, have mainly been ignored. For every 100 psychology papers dealing with anxiety or depression, only one concerns a positive trait.
B
A few pioneers in experimental psychology bucked the trend. Professor Alice Isen of Cornell University and colleagues have demonstrated how positive emotions make people think faster and more creatively. Showing how easy it is to give people an intellectual boost, Isen divided doctors making a tricky diagnosis into three groups: one received candy, one read humanistic statements about medicine, one was a control group. The doctors who had candy displayed the most creative thinking and worked more efficiently. Inspired by Isen and others, Seligman got stuck in. He raised millions of dollars of research money and funded 50 research groups involving 150 scientists across the world. Four positive psychology centres opened, decorated in cheerful colours and furnished with sofas and baby-sitters. There were get-togethers on Mexican beaches where psychologists would snorkel and eat fajitas, then form "pods" to discuss subjects such as wonder and awe. A thousand therapists were coached in the new science.
C
But critics are demanding answers to big questions. What is the point of defining levels of happiness and classifying the virtues? Aren't these concepts vague and impossible to pin down? Can you justify spending funds to research positive states when there are problems such as famine, flood and epidemic depression to be solved? Seligman knows his work can be belittled alongside trite notions such as "the power of positive thinking". His plan to stop the new science floating "on the waves of self- improvement fashions" is to make sure it is anchored to positive philosophy above, and to positive biology below.
D
And this takes us back to our evolutionary past. Homo sapiens evolved during the Pleistocene era (1.8 m to 10,000 years ago), a time of hardship and turmoil. It was the Ice Age, and our ancestors endured long freezes as glaciers formed, then ferocious floods as the ice masses melted. We shared the planet with terrifying creatures such as mammoths, elephant-sized ground sloths and sabre-toothed cats. But by the end of the Pleistocene, all these animals were extinct. Humans, on the other hand, had evolved large brains and used their intelligence to make fire and sophisticated tools, to develop talk and social rituals. Survival in a time of adversity forged our brains into a persistent mould. Professor Seligman says: "Because our brain evolved during a time of ice, flood and famine, we have a catastrophic brain. The way the brain works is looking for what's wrong. The problem is, that worked in the Pleistocene era. It favoured you, but it doesn't work in the modem world."
E
Although most people rate themselves as happy, there is a wealth of evidence to show that negative thinking is deeply ingrained in the human psyche. Experiments show that we remember failures more vividly than successes. We dwell on what went badly, not what went well. Of the six universal emotions, four anger, fear, disgust and sadness are negative and only one, joy, is positive. The sixth, surprise, is psychologist Daniel Nettle, author of Happiness, and one of the Royal Institution lecturers, the negative emotions each tell us "something bad has happened" and suggest a different course of action.
F
What is it about the structure of the brain that underlies our bias towards negative thinking? And is there a biology of joy? At Iowa University, neuroscientists studied what happens when people are shown pleasant and unpleasant pictures. When subjects see landscapes or dolphins playing, part of the frontal lobe of the brain becomes active. But when they are shown unpleasant images a bird covered in oil, or a dead soldier with part of his face missing the response comes from more primitive parts of the brain. The ability to feel negative emotions derives from an ancient danger-recognition system formed early in the brain's evolution. The pre-frontal cortex, which registers happiness, is the part used for higher thinking, an area that evolved later in human history.
G
Our difficulty, according to Daniel Nettle, is that the brain systems for liking and wanting are separate. Wanting involves two ancient regions the amygdala and the nucleus accumbens that communicate using the chemical dopamine to form the brain's reward system. They are involved in anticipating the pleasure of eating and in addiction to drugs. A rat will press a bar repeatedly, ignoring sexually available partners, to receive electrical stimulation of the "wanting" parts of the brain. But having received brain stimulation, the rat eats more but shows no sign of enjoying the food it craved. In humans, a drug like nicotine produces much craving but little pleasure.
H
In essence, what the biology lesson tells us is that negative emotions are fundamental to the human condition, and ifs no wonder they are difficult to eradicate. At the same time, by a trick of nature, our brains are designed to crave but never really achieve lasting happiness.
Question 14-20

试题分析
Question 14-26
题目类型：
题号
定位词
文中对应点
题目解析
14
Three groups
B段第2句
B段讲述了少数心理学家对积极情绪的研究。从第2句话开始，文章详述了实验的方法，题干中的positive icon指代文中的candy。
本题答案为B
15
Ignored，only
A段最后两句
A段是关于早期心里学家研究幸福的方法。从该段最后两句可以看出，积极的情绪在当时的研究被ignored，并且在100个试验中，only one concerns a positive trait。这里的ignored/only/a都是在映射题干中的poorly researched。
本题答案选A
16
Structure of the brain
F段第1句
F段讲述了积极和消极想法的大脑结构的生物学基础。从第一句话的structure of brain可以看出，本段会研究brain action。
本题答案选F
17
Critics, big question
C段第1句
C段是针对B段的观点，批评家质疑少数心理学家研究幸福的方式。从critics, big question, what is the point of…等地方，均可以看出题干中所述的skeptical attitude。
本题答案选C
18
Wanting, liking
G段第1句
G段落主要讲wanting和liking的在大脑系统中的区别。从第1句开始，该段多次出现wanting和liking。
所以本题答案选G
19
Brick of nature
H段第2句
H段是全文最后一段，所以很容易于题干中的conclusion联系在一起。另外在H段第 2句也出现了brick of nature,指代题干中的nature of brains。
本题答案选H
20
Six universal emotion
E段中间
E段中提到了人类最基础的六种情感，对应题干中的human emotional categories。
本题答案选E
21
Candy
B段
B段中详细描述了实验的三个分组情况。Into three groups: one received candy, one…
所以本题可以从原文中直接找到答案为candy。
22
What is the point of defining…
C段
从题干中的Since critics可得知此题对应原文中的C段。该段第2句话what is the point of defining levels of happiness and classifying the virtues。所以本题需要填写define的名词definition。
23
Professor Seligman, adversity
D段倒数第三局
D段倒数第3句：Professor Seligman says: because our brain evolved during a time of ice, flood and famine, we have a catastrophic brain。从题干中的Professor Seligman提示了答案应该从这句话中寻找。另外题干中的adversity对应了文章中的ice flood和famine。因此每题应该填catastrophic brain
24
Pleasant picture
E段第3句
E段第3句 讲述了pleasant and unpleasant picture对人类大脑的影响，之后紧接着提到了landscapes and dolphins playing。可见这里的positive image应该填文章中对应的pleasant picture，即landscapes and dolphins playing。
25
Unpleasant images
E段第4句
此题答案紧接着上一题。作者在E段中描述了pleasant picture之后，紧接着提到了unpleasant image(picture)。在该句的末尾处comes from more primitive parts of the brain可以找到改题的答案为 more primitive parts
26
Separate, deeply ingrained, wanting and liking, lasting happiness
E、G、H段
A选项: G段的第一句话brain system for liking and wanting are separate，因此选项中的mix together是错误的。
B选项: 在E段中，作者主要表述了消极思想和情感在大脑中会留下深刻的记忆，并很难被抹去: negative thinking is deeply ingrained in the human psyche。Deeply ingrained和题干中的be easily rid of矛盾。
C选项：G段最后一句，drug like nicotine produces much craving but little pleasure。看似与题干很吻合但是却在意思上大相径庭。G段的核心思想是在强调happiness和满足wanting后的satisfaction是两个概念。题干中的nicotine只是满足了人类大脑的wanting，但是不会带来pleasant，更不会带来happiness。所以这个选项也是错误的。
D选项：H段最后一句，our brain are designed to crave but never really achieve lasting happiness意思与题干一致，表述了由于大脑结构导致了很难持续或者幸福感。
所以本题选D
参考译文：
科学家可以告诉我们什么是幸福吗
A
经济学家认为，如果人们会把自己描述成幸福的，那么他们就是幸福的.然而 心理学家却要区分不同幸福感之间的差别。幸福最中等的水平是一种开心或是快乐的感觉。但是有时幸福是对生活的一种评判，认为生活是令人满意的，而这似乎是不涉及感情范畴的。受人敬仰的心理学家Martin Seligman率先致力于关于幸福的研究。不幸的是，我们并不是天生就会感到幸福;而所幸的是，我们可以做一些关于幸福的事情。关于幸福的研究最早要追溯 到130年前在Leipzig的实验室，那时心理学对“善良”和“满足”还知之甚少， 大部分的心理学家都在研究“软弱”和“痛苦”。图书馆里的书涉及的理论都是关于我们为什么会悲伤，担忧和生气这类的情绪。研究生活乎顺时发生的事情在当时看来是不靠谱的。积极正面的体验，比如说快乐，善良，利他主义和英雄主义在当时常常是被人们忽略的。在每100篇关于焦虑和压抑的心理学论文中，只有一篇会涉及积极的心理状态。
B
少数的实验心理学家引领了有关幸福研究的潮流。康奈尔大学的Alice Isen教授和她的同事致力于研究正面的情感如何让人们思维更敏捷以及更有创造力。为了展示正面的情感是怎样迅速地提升一个人的智力，Isen教授通过一个巧妙的诊断将参加实验的医生分为3组：一组收到了糖果，一组朗读人本主义的宜言，一组则作为控制对照组，(实验结果表明，)收到糖果的医生的思维更具创造性同时工作也更高效，受到Isen教授和其他人的启发，Seligman也投身关于幸描的研究，他等集到了几百万美金的研究经费，用以资助全世界150名科学家组成的50个研究小组。4家“积极心理学”中心成立，用令人愉悦的颜色装饰， 配有沙发和保姆。心理学家聚集在墨西哥的沙滩上享受着潜水的乐趣，品尝墨西哥菜肴fajitas，他们还分成小组讨论有关“夸迹”和“敬畏"的话题。还有一千名临床医学家接受这项新科学项目的培训。
C
但是一些批评家要求心理学家回答一些重大的问题，比如说，什么是定义不同幸福水平的标准以及如何将这些特点分类?这些关于幸福的概念难道不是糢糊不清而且无法被这实的吗?当四处还有饥荒，洪水和经济萧条的时候，将这些研究基金用于积极心态的研究合适吗?Seligman知道他的工作会被别人轻看，还可能会被人冠以诸如“积极思考的力量”此类的陈词滥调。因此，为了让这样新的科学研究不要浮于自我满足的状态，就要确保这项研完和“枳极心理学”相联系，又以“枳极生物学”作为基础。
D
这就需要我们回到人类的进化史，人类是从更新世时代(180万到1万年前)开始进化的，那是一个充满艰难和动荡的时代。在冰河世纪，我们的祖先先是忍受冰川形成的寒冷，然后是冰川消融时的泛滥的洪水。人们还得和那些令人毛骨悚然的生物比如说猛犸象和体型如大象般巨大的地懒以及长着锐利犬牙的猫共同生存。但是到了更新世的末期，所有的这些动物都灭绝了，人类却进化出了脑容量更大的大脑，并且通过自己的智力学会生火和*较复杂的工具，还学会了说话并且形成了一些社会礼仪。在逆境中生存将人类变得更加有恒心和毅力。Seligman教授说道：“因为我们的大脑是在一个充满冰川，洪水和饥荒的年代进化来的，我们的大脑经历了太多患难—灾难性，所以我们的大脑的运作模式就是 “发现哪里出了问题”。但问题是，这在更新世那样的时代是起作用的，在那时这对人类是有益的，但是在现代社会就不起作用了。
E
尽管大多数人评价自己很幸福，但是大量证据显示消极的想法还是在人类心中根深蒂固。实验显示，较成功而言，失败更容易被我们牢牢记住。我们总是在思想一些不顺利的事情，而不是那些顺利的好的事情。在6种基本的情绪中，有4种是消极的，它们是：生气，害怕，厌恶和悲伤，而只有一种是积极的，它就是喜悦。(第6种情绪是惊奇，属于中性。)心理学家同时也是《幸福》这本书的作者Daniel Nettle和皇家学院的一位学者认为，消极的情绪总是告诉我们“一些不好的事情已经发生了”，从而会让我们采取不一样的行动。
F
究竟是什么样的大脑结构让我们会倾向于有消极的想法呢?“快乐”这样的情绪有生物学基础吗?爱荷华大学的神经学家研究了当人们看到令人愉悦的图片和让人不舒服的图片时的情况。当人们看到风景或是海豚玩耍时，大脑的额叶会变得活跃。但是当他们看到一些让人不舒服的图片比如说一只小鸟被埋在土里时，或是一个战死的战士面部还有部分缺失时，大脑最原始的部分会做出反应。这种识别消极情绪的能力是从古时候大脑进化早期形成的危险识别系统来的。大脑前额叶皮质是产生幸福感的部位，是用来进行一些高级的思考，是人类晚些时期进化来的。

据Daniel Nettle所言，研究的困难在于大脑对于“喜欢”和“欲望”(wanting and liking)的机制是分开的，“欲望”涉及两个最初大脑发育的部位，也就是扁桃体和神经大脑区，它们通过化学多巴酚传递信息来形成大脑的奖励机制。它们常常是让人们很期待吃完东西的*或是对药品上瘾。小白鼠会不停地击打栅栏来获取对大脑“欲望”情绪的电*，而忽略异性同伴，但是获得大脑*的小白鼠虽然吃得更多，但是并没有迹象表明它在吃到自己渴想的食物后有一种满足感。对人而言，像尼古丁这样的物质会让人想要摄取更多但是却带来很少的*。

从本质上来看，生物课可以告诉我们消极的情绪是人类生存的基本情绪，所以难怪它很难根除。与此同时，让人觉得很诡异的是，我们的大脑总是想要的很多，但是却很难真正得到持续的幸福感。
