差序氛围感知对职场孤独感的影响：相对剥夺感的中介作用Dhurakij Pundit University，Thailand Bangkok摘要：本研究的目的在于深入探究在中国本土文化背景下，差序氛围感知对职场孤独感的影响。

本研究采用分层抽样的方式揭示差序氛围感知对职场孤独感的影响机制和相对剥夺感的中介作用。

结果显示差序氛围感知与职场孤独感存在显著关联，差序氛围感知通过相对剥夺感的中介作用影响职场孤独感的产生。

这为深入了解员工在职场中的心理体验和行为反应提供了重要的理论和实践意义。

关键词：差序氛围感知；职场孤独感；相对剥夺感1.职场孤独感的概述职场孤独感作为社会互动和个人关系质量的消极反映，被描述为一种不受欢迎的心理状态，这是由于缺乏定性的人际关系和无法社交而导致的。

职场孤独是单维的结构，是由社会中关系的缺陷引起的。

而职场孤独感的多维观点认为可以分为环境因素和个人因素，而环境因素包含组织层面和人际关系影响，导致职场孤独感形成的组织层面的原因又包括层级和组织的规模。

因此，孤独感和孤独之间存在差异。

孤独感是个体对社交联系的主观感受和情感反应，而孤独是个体实际社交联系的客观状态。

一个人可能感到孤独，但并不一定意味着他们处于孤立的状态；同样，一个人可能与他人保持社交联系，但仍然感到孤独。

这说明了孤独感和孤独之间的不同2．差序氛围感知的概述差序氛围感知是指个体对组织内部人际关系特别是领导与下属之间关系疏密状态的感知。

当员工感知到组织内存在圈层关系和分配不公平等特征时，他们可能会感到不满和不公正，从而对组织的整体氛围产生负面的认知偏差。

这种认知偏差可能导致员工之间的互信和合作减少，增加组织内冲突和紧张的组织氛围。

差序氛围感知主要包括三个方面：偏私对待、相互依附和亲信角色。

偏私对待：偏私对待指员工对于组织内差别对待的感知。

相互依附：相互依附指员工对组织内部某些人的关心与支持程度的感知。

亲信角色：亲信角色指员工对于组织内关系导向的感知。

In an era where modernity is rapidly overshadowing the past,it is crucial to preserve and pass on the rich tapestry of traditional arts.These arts are not just aesthetic expressions but are also the carriers of cultural identity,history,and the collective wisdom of generations.Heres a detailed look at why it is essential to keep these arts alive and how we can do so.The Importance of Traditional Arts1.Cultural Identity:Traditional arts are a reflection of a communitys values,beliefs,and way of life.They provide a sense of belonging and continuity,connecting individuals to their roots and to each other.2.Historical Significance:These arts often document the evolution of societies,providing insights into the past that can inform the present and future.They serve as a living archive of human creativity and resilience.cational Value:Engaging with traditional arts can be a powerful educational tool, teaching skills such as patience,attention to detail,and creativity,as well as imparting knowledge about history,culture,and craftsmanship.4.Economic Contribution:In many communities,traditional arts are a source of income and employment,contributing to local economies and supporting the livelihoods of artisans.Challenges in Preserving Traditional Arts1.Modernization:The allure of modern technology and lifestyles can lead to the neglect of traditional practices,as younger generations may not see the relevance of these arts in their daily lives.2.Economic Pressures:The commercialization of culture can lead to the exploitation of traditional arts,with the focus shifting from preservation to profit,often at the expense of authenticity and quality.ck of Support:Without adequate funding and support,traditional arts may struggle to survive,particularly in the face of competition from more popular or lucrative forms of entertainment.Strategies for Preserving Traditional Artscation and Awareness:Schools and communities can integrate traditional arts into their curricula and activities,fostering an appreciation for these practices from an early age.2.Support for Artisans:Providing financial support,training,and resources can help traditional artists continue their work and pass on their skills to the next generation.3.Cultural Exchange:Encouraging the exchange of traditional arts between different cultures can help to broaden understanding and appreciation,as well as to inspire new forms of creative expression.4.Digital Preservation:Utilizing modern technology to document and archive traditional arts can ensure their survival even if the physical practices fade away.munity Involvement:Engaging the community in the preservation of traditional arts can create a sense of collective responsibility and pride,as well as provide a platform for artists to share their work.The Role of TechnologyWhile technology may pose a threat to traditional arts,it can also be harnessed as a tool for preservation.Digital platforms can provide a space for traditional artists to showcase their work,reach new audiences,and connect with others who share their passion.Social media,virtual reality,and online marketplaces can all play a role in keeping traditional arts alive in the digital age.ConclusionThe preservation of traditional arts is a multifaceted endeavor that requires the commitment of individuals,communities,and institutions.By valuing these arts for their intrinsic worth and their contribution to our collective heritage,we can ensure that they continue to enrich our lives and the lives of future generations.It is a responsibility that we owe to our past,a gift to our present,and an investment in our future.。

CD汰换合同概率1. 引言在金融市场中，银行发行的证券产品之一是储蓄存单（Certificate of Deposit，简称CD）。

CD是一种定期存款证券，投资者在购买CD时向发行银行存入一定金额，存款期限一般为几个月到几年不等。

与活期存款不同，CD定期存款在存入一段时间后才可以提取。

CD汰换合同概率是指投资者在存款期满后选择不再续存的概率，其高低直接影响到银行的资金流动和利润水平。

2. 影响CD汰换合同概率的因素CD汰换合同概率的大小受到多方面因素的影响，以下是一些对CD汰换合同概率产生影响的主要因素：2.1 利率水平存款利率是投资者选择CD而非其他投资品种的主要因素之一。

当其他投资品种的收益率高于CD利率时，投资者更可能选择提前解除CD合同，并将资金转移到具有更高收益的投资渠道。

因此，利率水平对CD汰换合同概率有明显的影响。

2.2 经济形势经济形势对CD汰换合同概率产生直接影响。

在经济繁荣期，投资者可选择的投资机会多，对CD的需求可能下降，导致CD汰换合同概率上升。

而在经济衰退期，投资者为了安全起见，可能更倾向于选择定期收益稳定的CD产品，导致CD汰换合同概率下降。

2.3 CD期限CD期限是指存款的持有时间，一般来说，CD期限越长，投资者解除合同的概率越低。

这是因为较长期限的CD产品往往可以获得更高的利息，投资者更愿意等待存款期满后一次性取出本金和利息。

2.4 投资者特点投资者个体的特点也会对CD汰换合同概率产生影响。

例如，对于年轻的投资者来说，他们可能更注重短期流动性，更倾向于选择活期存款或其他更灵活的投资品种，导致CD汰换合同概率上升。

而对于年长的投资者来说，他们更注重稳定收益和风险控制，更倾向于选择CD产品，导致CD汰换合同概率下降。

3. 影响CD汰换合同概率的模型和方法为了准确预测CD汰换合同概率，研究者们提出了许多模型和方法。

以下是几种常用的影响CD汰换合同概率的模型和方法：3.1 马尔科夫链模型马尔科夫链模型是一种数学模型，可以用来描述状态随时间变化的概率过程。

世代交叠模型的主要结论和优缺点引言世代交迭模型是国内外学者在研究社会不同世代之间关系时提出的一种分析框架。

这一模型试图通过对不同世代之间的交互、互动关系进行整体的认识和理解。

在接下来的文章中，我将深入探讨世代交迭模型的主要结论和优缺点，以便能更深入地理解这一理论框架。

一、世代交迭模型的主要结论在对世代交迭模型进行全面评估后，我们可以得出以下主要结论：1. 交互影响：世代之间不是孤立存在的，而是相互交织、相互影响的。

老一代对年轻一代的行为、态度有直接影响，年轻一代则影响着老一代的生活方式、消费观念等。

2. 传统传承：世代交迭模型也强调了传统文化、价值观在不同世代之间的传承。

老一代的传统观念和理念会影响年轻一代的认知和行为，而年轻一代也在向老一代传递新的观念和理念。

3. 社会变迁：通过世代交迭模型，我们能够更清晰地观察和理解社会的变迁。

不同世代在不同的社会背景下成长，他们的生活方式、工作方式等也会受到相应的影响，世代之间的差异和变迁也呈现出来。

二、世代交迭模型的优缺点在深入探讨世代交迭模型的优缺点后，我们可以得出以下结论：优点：1. 全面性：世代交迭模型能够全面而深入地观察不同世代之间的关系，包括传承、交互等方面。

这有助于我们更好地理解社会变迁的规律。

2. 跨学科性：世代交迭模型涉及到社会学、心理学、人类学等多个学科领域，能够提供一个多维度、多角度的分析框架。

3. 实践意义：世代交迭模型不仅停留在理论层面，更有着强烈的实践意义。

它可以指导我们更好地处理社会中不同世代之间的关系，有助于社会和谐和稳定的发展。

缺点：1. 历史局限：世代交迭模型在某种程度上受到特定历史条件的限制，无法对每个社会、每个群体都适用。

在实际运用中需要结合实际情况进行灵活处理。

2. 个体差异：世代交迭模型存在着忽略个体差异的缺点。

它更多地强调了整体性和整体变迁，而对于不同个体之间的差异性没有给予足够的关注。

3. 研究方法：世代交迭模型目前的研究方法相对较为单一，更多地是从定性研究的角度出发，定量研究的方法还需要进一步完善和拓展。

旅游经济、环境规制与入境旅游碳排放旅游经济、环境规制与入境旅游碳排放马继心,谢霞2,3,秦放鸣1(1.新疆大学经济与管理学院，新疆乌鲁木齐830046;2新疆大学旅游学院，新疆乌鲁木齐830046;3•新疆历史文化旅游可持续发展重点实验室，新疆乌鲁木齐830046)摘要：文章基于“自上而下”法对2001—2017年中国入境旅游碳排放量进行了估算，通过对IPAT模型和STIRPAT模型的扩展，构建了探究旅游经济、环境规制与入境旅游碳排放关系的固定效应回归模型，并采用全国面板数据展开实证分析，得出以下结论：一是旅游经济与入境旅游碳排放之间呈倒“U”型环境库兹涅茨曲线关系；二是环境规制与入境旅游碳排放呈负相关关系；三是旅游经济增长对入境旅游碳排放的促进作用大于环境规制的抑制作用，环境规制强度增加并未通过抑制旅游经济的增长而减少入境旅游的碳排放。

并据研究结果提出环境规制强度需从宏观顶层设计；环境规制方法应多措并举；通过调整能源消耗结构实现对入境旅游碳排放的抑制；积极践行低碳旅游发展模式，走旅游可持续发展道路的对策建议。

In todays job market,gender discrimination remains a pervasive issue that affects the career prospects and opportunities of individuals,particularly women.This essay will explore the various forms of gender discrimination in the workplace,its impact on individuals and society,and potential solutions to address this problem.Forms of Gender Discrimination in Job Applications1.Biased Job Advertisements:Some job postings explicitly or implicitly favor one gender over the other,using language that suggests a preference for male or female candidates.2.Resume Screening:Studies have shown that resumes with traditionally male or female names receive different levels of attention,with male names often being more likely to be shortlisted for interviews.3.Interview Process:During interviews,questions may be genderbiased,focusing on aspects of a candidates personal life that are irrelevant to the job,such as family planning or childcare responsibilities.Impact of Gender Discrimination1.Career Advancement:Women are often overlooked for promotions or leadership roles, leading to a glass ceiling effect where they are unable to reach the top of their chosen career paths.2.Salary Disparity:On average,women earn less than men for the same work, contributing to a significant wage gap that can have longterm financial implications.3.Mental Health and Wellbeing:Experiencing discrimination can lead to increased stress, anxiety,and a sense of injustice,affecting the mental health and overall wellbeing of individuals.Solutions to Address Gender Discrimination1.Legislation and Policies:Implementing and enforcing laws that prohibit gender discrimination in the workplace can help create a more level playing field for all job seekers.2.Awareness and Training:Companies should provide training to hiring managers and employees to recognize and combat unconscious biases that may influence hiringdecisions.3.Transparent Hiring Practices:By making the hiring process transparent,companies can ensure that all candidates are evaluated based on their qualifications and skills rather than their gender.4.Supportive Workplace Culture:Fostering a culture that values diversity and inclusion can help to break down stereotypes and create a more equitable work environment.5.Role Models and Mentorship:Encouraging women in leadership positions to mentor and support other women can help to inspire and empower the next generation of female professionals.In conclusion,gender discrimination in the job market is a complex issue that requires a multifaceted approach to address.By recognizing the problem,implementing policies, and fostering a culture of equality,we can work towards a more inclusive and equitable job market for all.。

定义色的色域边界的测试目标Phil Green彩色影像集团LCP的，英国伦敦2000年12月1．简介在生产中的一个色域是颜色可以在其上复制的范围。

这个范围将取决于许多因素，其中最重要的是介质本身的物理性能和它们一起使用的着色剂。

其他因素包括介质存在的条件，半色调或采纳抖动的方法，和在渲染过程中的任何特性或限制，如固体密度或墨水限制。

在一些行业如报纸的生产，这些因素很多是有一定程度的标准化，并有可能定义一个色域将适用（有一些变化）跨越大部分产品印刷的过程。

虽然色域通常代表两个方面（如xy色度或CIELAB的a* / b *值），这可能会引起误解的原因有两个。

首先，它忽略了亮度范围的可复制（也称为动态范围），这是色域的一个重要方面;第二，通过忽略亮度尺寸可能会出现一个给定的色域里面的颜色，而事实上并非如此。

对于硬拷贝的媒体，如着色剂的组合并不按照简单的加法原则，色域在色彩空间如CIELAB空间中是一种不规则的固体。

在CIELAB中比较不同介质的色域，我们注意到一些非常大的差异，也就是说，摄影逆转材料，而中冷置新闻纸用于重现。

可能对色域最明显有用的信息是援助在原始和繁殖媒体之间的映射颜色的过程。

色域映射算法使用双方媒体的色域边界，来确定需要多少压缩，使比较大的色域适合较小的色域。

这通常需要找到与色域边界一行的交集，通过要映射的点从收敛域边界点（通常在位于轴色差）找。

在最近的一项色域映射模型研究中，来源于高品质的复制品经验发现与经验数据拟合的模型可以通过由包括线性插值从模型中的色域边界形状的'尖'（在给定色相角度最大色度）来改善。

1.1色域边界计算色域边界的许多方法被描述在[1,2,3,4,5,6]。

这些方法的主要特点由Morovic[6进行了总结]。

不同的媒体和图像的色域也已在最近文件[7,8]中进行了比较。

在着色剂空间，色域边界可以被视为一个立方体因为在顶点它有固体着色剂和他们的第二组合的面孔。

It’s a striking number for a city with a population of about 850,000, and it was enough for Airbnb to win a major victory in local elections, as San Francisco voters struck down a debatable rule that would have placed time restrictions and other regulations on short-term rental services.The company fiercely opposed the measure, Proposition F, with a nearly $10 million advertising campaign. It also contacted its San Franciscan users with messages urging them to vote against Proposition F.Most people think of Airbnb as a kind of couch-surfing app. The service works for one-night stays on road trips and longer stays in cities, and it often has more competitivepricing than hotels. It’s a textbook example of the “sharing economy”, but not everyone is a fan.The app has had unintended consequences in San Francisco. As the San Francisco Chronicle reported last year, a significant amount of renting on Airbnb is not in line with the company’s image: middle-class families putting up a spare room to help make ends meet. Some users have taken advantage of the service, using it to turn their multiple properties into vacation rentals or even full-time rentals. Backers of Proposition F argued that this trend takes spaces off the conventional, better-regulated housing market and contributes to rising costs.“The fact is, widespread abuse of short-term rentals is taking much needed housing off the market and harming our neighborhoods,” said ShareBetter SF, a group that supported Proposition F. Hotel unions have protested the company’s practices in San Francisco and other cities, saying that it creates an illegal hotel system.San Francisco is in the middle of a long-term, deeply rooted housing crisis that has seen the cost of living explode. Actually, explode is a generous term. The average monthly rent for an apartment is around $4, 000. Located on a narrow outcropping of land overlooking the bay, San Francisco simply doesn’t have enough space to accommodate the massive inflow of young, high-salaried tech employees flocking to Silicon Valley.As the Los Angeles Times reported, some San Francisco residents supported the measure simply because it seemed like a way to check a big corporation. Opponents of Proposition F countered that the housing crisis runs much deeper, and that passing the rule would have discouraged a popular service while doing little to solve the city’s existing problems.8．The intention of Proposition F is to ________.A．place time limits in local election.B．set limits on short-term rental.C．strike down a controversial rule.D．urge users to vote against Airbnb. 9．What is the negative consequence of Airbnb on San Francisco?A．It shrinks the living space of middle-class families.B．Users are taken advantage of by the service financially.C．It makes the house market more competitive.D．It indirectly leads to high house rental price.10．The housing crisis in San Francisco results from ________.A．explosion of the living cost B．its geographic characteristicsC．generosity of local enterprises D．inflow of migrant population11．The author’s attitude toward Proposition F is ________.A．objective B．supportiveC．negative D．indifferentHumans are not the only ones who underwent self-domestication. So did our close relatives, the bonobos, and the species we call our best friend. A tiny proportion of the genome differentiates dogs from wolves, and yet millions of dogs are comfortably curled up in our homes, while wolves move around at the edge of extinction.When our research group began its work almost 20 years ago, we discovered that dogs also have extraordinary intelligence: they can read our gestures better than any other species. Wolves, in contrast, are mysterious and unpredictable. Their home is the wilderness, and that wilderness is shrinking.But not so long ago the evolutionary race between dogs and wolves was so close, it was unclear who would win. Dogs, in fact, did not descend from wolves. Instead, dogs and wolves shared a wolflike ancestor.Folklore supposes that humans brought wolf puppies into camp and domesticated them. Or as wolf expert David Mech wrote in 1974, “Evidently early humans tamed wolves and domesticated them, eventually selectively breeding them and finally developing the domestic dog from them.” But this story has not held up. Taming an animal occurs during its lifetime. Domestication happens over generations and involves changes to the genome.So how did wolves turn into dogs? Back in the Ice Age, as our human populations grew more sedentary, we probably created more rubbish, which we then dumped outside our camps. These leavings would have included tempting pieces of food for hungry wolves. Not every wolf would have been able to scavenge, however. These animals would have had to be unafraid of humans, and if they displayed any aggression toward us, they would have been killed. After generations of selection for friendliness without intentional selection by humans, this special population of wolves would have begun to take on a different appearance. Coat color, ears, tails: all probably started to change.Animals that could respond to our gestures and voices would be extremely useful as hunting partners and guards. They would have been valuable as well for their warmth and companionship, and slowly we would have allowed them to move from outside our camps to our firesides. We did not domesticate dogs. The friendliest wolves domesticated themselves.12．What can be summarized about wolves and dogs from the first three paragraphs?A．Wolves are smarter than dogs.B．They are very much racially divided.C．They are close relatives but dogs seem to be on the winning side.D．Dogs have made their ways to indoor life while wolves to the wild.13．What is the meaning of the underlined word “sedentary” in paragraph 5?A．diverse B．limitedC．living in the same place D．involving regular migration 14．What does the author conclude from the history of dogs and wolves?A．Dogs evolved from wolves.B．Selective breeding developed domestic dogs.C．Taming and domesticating an animal are the same thing.D．Friendliness as a quality translates into an evolutionary strategy.15．Which of the following is suitable for a title?A．From Wolf to Dog B．Dog: Our Favorite PetC．An Intentional Domestication D．A Competition Story between Wolf and Dog二、七选五Color is in everything we touch, taste, smell and feel. It evokes(唤起) emotion without any thought. 16 We are all familiar with it, but do you know the following facts?Silver will save your life. When buying a new car and finding yourself facing various choices, you can’t think clearly. Your best choice is to go with silver. Silver­colored cars are least likely to be involved in a car accident. 17 Another reason is the silver color's ability to have a look of cleanliness.18 Tough prisoners and crazy patients It is the color commonly used to help calm down those who are out of control. So it surely has a useful place and a purpose, other than decorating a dress or Barbie's dream house.Yellow makes you hungry. Yellow and orange are not recommended for use in kitchens, as they have a positive influence on your appetite. 19 I’m not normally one for conspiracy(阴谋) theories­ but perhaps there’s something in it for them if we remain ignorantof yellow’s effects.Color is an imaginary friend. Technically, it’s all in our heads: color does not exist at all.20 So, if you start a heated debate over color combinations with someone that you are certain has a low IQ or is just color­blind，remember it's a pointless argument and you should drop it instantly. You're both wrong.A．Pink comforts the nerves.B．Blue is the most common favorite color.C．They are most noticeable on the road and in low light.D．Yellow­colored walls seldom leave us wanting more food.E．It can be the focus of our careers, our lifestyle and the fun we have.F．Then where would our restaurant owners be without the clever tricks?G．Color tries to make sense of the huge amount of information from the outer world.三、完形填空“some teachers suggested that we hire a local artist to paint our school mascot on the school wall. Would you like to participate in that?”“Really?” Brian hesitated, 33 to believe it.“Yes, but it’s hard work, and we can consider it part of your 34 ,” Mr. Johnson said, trying to hide his 35 as he picked up the phone.21．A．Gradually B．Generally C．Usually D．Suddenly 22．A．curiosity B．disappointment C．fear D．relief 23．A．wiped B．examined C．scanned .D．suspected 24．A．spied B．reflected C．commented D．hit 25．A．make B．report C．describe D．retell 26．A．hesitantly B．patiently C．directly D．sympathetically 27．A．Ashamed B．Surprised C．Excited D．Satisfied 28．A．slowly B．late C．deliberately D．right 29．A．fortunate B．miserable C．relaxed D．naughty 30．A．repaint B．hide C．build D．repair 31．A．And B．So C．Or D．But 32．A．promise B．choice C．decision D．appointment 33．A．unable B．unwilling C．unlikely D．unhappy 34．A．responsibility B．talent C．devotion D．punishment 35．A．regret B．anger C．smile D．pride四、用单词的适当形式完成短文阅读下面材料，在空白处填入适当的内容(1个单词)或所给单词的正确形式。

一种新的部分神经进化网络的股票预测(英文)一种新的部分神经进化网络的股票预测自从股票市场的出现以来，人们一直在寻求能够提前预测股票走势的方法。

许多投资者和研究人员尝试使用各种技术分析工具和模型来预测股票未来的走势，但是股票市场的复杂性和难以预测性使得这变得困难重重。

因此，寻找一种能够准确预测股票走势的方法一直是金融界的热点问题。

近年来，人工智能技术在金融领域的应用日益增多。

其中，神经网络是一种被广泛使用的工具，它可以自动学习和识别模式，并根据所学的模式进行预测。

然而，传统神经网络在预测股票市场方面存在诸多问题，例如过拟合和难以处理大量数据等。

为了克服这些问题，本文提出了一种新的部分神经进化网络（Partial Neural Evolving Network, PNEN）模型来预测股票走势。

PNEN模型将神经网络和进化算法相结合，通过优化和训练来实现更准确的预测结果。

PNEN模型的核心思想是将神经网络的隐藏层拆分为多个小模块，每个小模块只负责处理一部分输入数据。

通过这种方式，模型可以更好地适应不同的市场情况和模式。

同时，采用进化算法来优化模型的参数，可以进一步提高模型的预测性能。

具体而言，PNEN模型包括以下几个步骤：1. 数据准备：从股票市场获取历史交易数据，并对数据进行预处理和归一化处理，以便更好地输入到模型中。

2. 构建模型结构：将神经网络的隐藏层拆分为多个小模块，通过进化算法来确定每个小模块的结构和参数。

进化算法通过优化模型的准确性和稳定性，以获得更好的预测结果。

3. 训练模型：使用历史数据集对模型进行训练，并通过反向传播算法来更新模型的权重和偏置。

同时，通过与进化算法的交互，不断调整模型结构和参数。

4. 预测结果：使用训练好的模型对未来的股票走势进行预测。

通过模型对市场的分析和判断，可以为投资者提供决策参考。

为了验证PNEN模型的效果，我们在实际的股票市场数据上进行了实验。

结果表明，与传统神经网络模型相比，PNEN 模型在预测股票走势方面具有更好的准确性和稳定性。

Research has shown animals can respond positively to classical music,and chickens are particularly responsive to baroque(巴洛克格),according to some studies.The composer,Hamish Oliver,__26__used the baroque tradition as a starting point and drew inspiration from composers such as Corelli,Bach,and Schnitke,wanted the piece to be playful by including sounds from a chicken's world. “The trumpet imitates the c hicken …the woodwind instruments are the cluckiest,especially if you take the reeds off. ”The early stages of composition were spent _______(test)out which instruments and sounds the chickens responded to best.“They didn't like any big banging. ”Bostock said,adding that when the birds respond positively to themusic,they tend__28__(wander)farther among the trees. Bostock now hopes chicken farmers around the world will use the piece of music to calm their own birds.For Oliver,having input from the farmers about __ 29__the chickens were responding to particular sounds and instruments was a highlight of the project.The symphony has searched exhaustively __30__any other examples of orchestras making music specifically for chickens and believes this to be a world-first,says Peter Biggs,the orchestra's chief executive.Section BDirections :Complete the following passage by using the words in the box. Each word can only be used once. Note thatA new way to reduce poachingResearchers are working on a pilot program backed by Russia's Rosatom Corp to inject rhino horns(犀牛角)with radioactive material,a strategy that could discourage consumption and make it easier to detect illegal trade.Poachers(偷猎者)killed 394 rhinos in South Africa for their horns last year,government data shows,with public and private game __31__lacking the resources needed to monitor vast tracts of land and protect the animals that live there.While the toll was a third lower than in 2019 and the sixth __32_drop,illegal hunting remains the biggest threat to about 20,000 of the animals in the country —the world's biggest population.Thousands of__33__sensors along international borders could be used to detect a small quantity of radioactive material____34___into the horns,according to James Larkin,a professor at the University of Witswatersrand in Johannesburg,who has a background in radiation protection and nuclear security. “A whole new_35_of people could be able to detect the illegal movement of rhino horn,"he said. Some alternate methods of discouraging poaching,including poisoning, dyeing and removing the horns,have raised a variety of opinions as to their virtue and efficacy.Known as The Rhisotope Project,the new anti-poaching __36__started earlier this month with the injection of an amino acid(氨基酸)into two rhinos' horns in order to detect whether the compound will move into the animals' bodies. Also,__37__studies using computer modeling and a replica rhino head will be done to determine a safe dose of radioactive material. Rhino horn is used in traditional medicine,as it is believed to cure disease such as cancer,__38__as a show of wealth and given as gifts."If we make it radioactive, these people will be hesitant to buy it,"Larkin said. "We're pushing on the whole supply chain. "Besides Russia's state-owned nuclear company,the University of Witwatcrsrand. scientists and private rhino owners are involved in the project. If the method is ___39__feasible,it could also be used to curb illegal trade in elephant ivory.“Once we have developed the whole project and got to the poi nt where we completed the proof of concept,then we will be making this whole idea ____40_to whoever wants to use it. " Larkin said.III. Reading ComprehensionSection ADirections: For each blank in the following passages there are four words or phrases marked A, B. C and D. Fill in each blank with the word or phrase that best fits the context.City air is in a sorry state. It is dirty and hot. Outdoor pollution kills 4. 2m people a year, according to the World Health Organization. Concrete and tarmac meanwhile,absorb the sun's rays rather than reflecting them back into space,and also ___41 ___plants which would otherwise cool things down by evaporative transpiration(蒸腾作用). The never-ceasing__42_of buildings and roads thus tums urban areas into heat islands,discomforting residents and worsening dangerous heatwaves.A possible answer to the twin problems of pollution and heat is trees. Their leaves may destroy at least some chemical pollutants and they certainly __43__tiny particles floating in the air. which are then washed to the ground by rain. Besides transpiration,they provide __44___.To cool an area effectively, trees must be planted in quantity. Two years ago, researchers at the University of Wisconsin found that American cities need 40%tree___45___to cut urban heat back meaningfully. Unfortunately,not all cities —and especially not those now springing up in the world's poor and middle-income countries —are __46___with parks, private gardens or a sufficient number of street trees. And the problem is likely to get worse. At the moment,55%of people live in cities. By 2050 that share is expected to reach 68%.One group of botanists believe they have at least a partial ___47___to this lack of urban vegetation. It is to plant miniature simulacra(模拟物)of natural forests, ecologically engineered for rapid growth. Over the course of a career that began in the 1950s,their leader,Miyawaki Akira, a plant ecologist at Yokohama National University in Japan. has developed a way to do this starting with even the most___ 48___deserted areas. And the Miyawaki method is finding increasing___ 49___around the world.Dr Miyawaki's insight was to deconstruct and rebuild the process of ecological succession, by which ___50___land develops naturally into mature forest.

For each of them there are four choices marked A,B,C and D. Choose the one that fits best according to the information given in the passage you have read.(A)From Marie Tussaud's Chamber of Horrors to Disneyland's Haunted Mansion(鬼屋)to horror-themed escape rooms,haunted house attractions have terrified and delighted audiences around the world for more than 200 years.These attractions turn out to be good places to study fear. They help scientists understand the body's response to fright and how we perceive some situations as enjoyably thrilling and others as truly terrible. One surprising finding;having friends close at hand in a haunted house might make you more jumpy,not less so.Psychologist and study co-author Sarah Tashjian,who is now at the University of Melbourne, and her team conducted their research with 156 adults,who each wore a wireless wrist sensor during their visit. The sensor measured skin responses linked to the body's reactions to stress and other situations. When the sensor picked up,for example,greater skin conductance —that is,the degree to which the skin can transmit an electric current —that was a sign that the body was more aroused and ready for fight or flight. In addition to this measure,people reported their expected fear (on a scale of 1 to 10)before entering the haunted house and their experienced fear (on the same scale)after completing the haunt.The scientists found that people who reported greater fear also showed heightened skin responses. Being with friends,Tashjian and her colleagues further found,increased physiological arousal during the experience,which was linked to stronger feelings of fright. In fact,the fear response was actually weaker when people went through the house in the presence of strangers.Other investigators have used haunted houses to understand how fear and enjoyment can coexist. In a 2020 study led by Marc Malmdorf Andersen,a member of the Recreational Fear Lab at Aarhus University in Denmark,scientists joined forces with Dystopia Haunted House. The Danish atraction includes such terrifying experiences as being chased by "Mr. Piggy",a large, chain-saw-wielding man wearing a bloody butcher's apron and pig mask. People between the ages of 12 and 57 were video recorded at peak moments during the attraction,wore heart-rate monitors throughout and reported on their experience. People's fright was tied to large-scale heart-rate fluctuations;their enjoyment was linked to small-scale ones. The results suggest that fear and enjoyment can happen together when physiological arousal is balanced "just right".56. Studing haunted house attractions helps scientists to learn about _____.A. the psychological effects of fear on individualsB. the history of horror-themed entertainmentC. the body's response to material rewardsD. the impact of technology on people's enjoyment57. How did Sarah Tashjian and her team conduct their research on haunted house experiences? A. By surveying participants.B. By analyzing historical records.C. By employing wireless wrist sensors.D. By using virtual reality simulations.58. What did Tashjian and her colleagues discover in their study?A. Being with fiends elevated level of physiological arousal.B. The fear reaction was stronger in the company of strangers.C. Psychological effect was unrelated to intensified feelings of fright.D. Those reporting lightened fear showed increased skin responses.59,It can be concluded from the 2020 study led by Marc Malmdorf Andersen that ____.A. fear and enjoyment can not happen at the same timeB. large-scale heart-rate fluctuations were linked to enjoymentC. the age of the participants was not related to the study's findingsD. fear and enjoyment can coexist under certain conditions(B)Is an electric vehicle right for you?Many people will ask themselvesthat question for the first time this year.Prices are falling,battery range is risingand mainstream brands are adding new EVs at a breakneck pace.Here are three things anybody seriously considering buying an EV should know:1. The price to install a 240v chargerAnybody who owns an electric vehicle needs a 240-volt charger at home. With one,you can recharge overnight,so you start every day with the equivalent of a full tank.Just a few years ago,home 240v EV chargers cost $2,500-$3,000,including installation,but prices have declined as competition grows with the number of EVs on the road.2. The time it takes to chargeAbout 80%of miles driven in EVs are powered by electricity charged at home,but you'll need to charge elsewhere occasionally. That's when charging time becomes a big deal,but how long it takes depends on a couple of factors.First,voltage from the charger. Getting 250 miles of range in seven hours from a 240v charger is fine when you're charging overnight at home,but it's a deal breaker if you're going 300 miles for a weekend getaway. In that case,you'll want to look for a 400v DC fast charger. They're not as common as 240v public chargers yet,but they're becoming more widespread.There's another factor:the on-board charger. It regulates how fast the battery can accept electricity. A vehicle with a higher-capacity on-board charger accepts electricity faster.3. Where to chargeGood route-planning apps will help you find chargers on a road trip.“Most people have no idea how many public charging stations are within,say,a 10-or 15- mile radius(半径)because they're small,people don't look for them or even don't know what to look for,and they're rarely signposted,"said journalist John Voelcker,who has studied EVs and charging exhaustively.4. On the horizonIf an EV doesn't meet your needs now, watch this space. They're coming closer,but large numbers of gasoline vehicles will remain in production for years. Beyond that,companies will keep making spare parts for oil-burners for decades.60. Which of the following statements is TRUE according to the passage?A. The price of installing a home EV charger has remained stable in the past few years.B. It's quite easy to identify the public charging stations with the help of striking signposts.C. Popular brands are introducing new EVs at an incredibly fast rate.D. An electric vehicle can't provide the same amount of energy as a completely filled fuel tank.61. The underlined phrase "watch this space" in the last paragraph probably means" _______ ”.A. give up the plan to purchase an EVB. make space for an EVC. find an alternative to EVD. keep an eye out for future developments62. This passage is mainly intended to _______ .A illustrate the factors charging time depends onB. offer advice on purchasing an electric vehicleC. look forward to the future of electric vehiclesL explain the reason for the falling prices of electric vehicles(C)Flinging brightly coloured objects around a screen at high speed is not what computers' central processing units were designed for. So manufacturers of arcade machines invented the graphics-processing unit (GPU),a set of circuits to handle video games' visuals in parallel to the work done by the central processor. The GPU's ability to speed up complex tasks has since found wider uses:video editing, cryptocurency mining and most recently,the training of artificial intelligence.AI is now disrupting the industry that helped bring it into being. Every part of entertainment stands to be affected by generative AI,which digests inputs of text,image,audio or video to create new outputs of the same. But the games business will change the most,argues Andreessen Horowitz,a venture-capital(VC)firm. Games interactivity requires them to be stuffed with laboriously designed content:consider the 30 square miles of landscape or 60 hours of music in “Red Dead Redemption 2”a recent cowboy adventure. Enlisting Al assistants to chum it out could drastically shrink timescales and budgets.AI represents an "explosion of opportunity"and could drastically change the landscape of game development. Making a game is already easier than it was:nearly 13,000 titles were published last year on Steam,a games platform,almostdouble the number in 2017. Gaming may soon resemble the music and video industries in which most new content on Spotify or YouTube is user-generated. One games executive predicts that small firms will be the quickest to work out what new genres are made possible by Al. Last month Raja Koduri,an executive at Intel,left the chip maker to found an Al-gaming startup.Don't count the big studios out,though. If they can release half a dozen high-quality titles a year instead of a couple,it might chip away at the hit-driven nature of their business,says Josh Chapman of Konvoy,a gaming focused VC firm. A world of more choices also favors those with big marketing budgets. And the giants may have better answers to the mounting copyright questions around Al. If generative models have to be trained on data to which the developer has the rights,those with big back-catalogues will be better placed than startups. Trent Kaniuga,an artist who has worked on games like "Fortnite",said last month that several clients had updated their contracts to ban Al-generated ant.If the lawyers don't intervene,unions might. Studios diplomatically refer to Al assistants as “co-pilots”,not replacements for humans.63. The original purpose behind the invention of the graphics-processing unit (GPU)was to______A. speedup complex tasks in video editing and cryptocurency miningB. assist in the developing and training of artificial intelligenceC. disrupt the industry and create new outputs using generative AID. offload game visual tasks from the central processor64. How might the rise of AI-gaming startups affect the development of the gaming industry?A. It contributes to the growth of user-generated content.B. It facilitates blockbuster dependency on big studios.C. It decreases collaboration between different stakeholders in the industry.D. It may help to consolidate the gaming market under major corporations.65. What can be inferred about the role of artificial intelligence in gaming?A. AI favors the businesses with small marketing budgets.B. AI is expected to simplify game development processes.C. AI allows startups to gain an edge over big firms with authorized data.D. AI assistants may serve as human substitutes for studios.66. What is this passage mainly about?A. The evolution of graphics-processing units (GPUs).B. The impact of generative AI on the gaming industry.C. The societal significance of graphics-processing units(GPUs).D. The challenges generative AI presents to gaming studios.Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can beTime to end Santa's 'naughty list'?Many of us have magical memories of Santa secretly bringing gifts and joy to our childhood homes —but is there a darker side to the beloved Christmas tradition?I was —and I'm happy to admit it —a loyal believer of Santa. I absolutely loved the magic of Christmas,especially Santa Claus,and my parents went above and beyond to encourage it. However,as I begin to construct my own Santa Claus myth for my daughter,I can't help but feel guilty. Could it undermine her trust in me?_____67______Backin1978,a study published in the American Journal of Orthopsychiatry(矫正精神医学)found that 85%of four-year-olds said they believed in Santa. In 2011,research published in the Journal of Cognition and Development found that 83%of 5-year-olds claimed to be true believers.I guess it's not all that surprising. _____68 _____He features in every Christmas TV show and movie. Each year the North American Aerospace Defence Command (NORAD)allows you to track Santa's journey on Christmas Eve. To reassure children during the pandemic in 2020,the World Health Organization issued a statement declaring that Santa was “immune”from Covid 19. And it's precisely this effort on behalf of parents,and society in general,to create such seemingly overwhelming evidence for the existence of Santa Claus that David Kyle Johnson,a professor of philosophy at King's College in Pennsylvania,describes as 'The Santa Lie' in his book The Myths That Stole Christmas. He highlights how we don't simply ask children to imagine Santa,but rather to actually believe in him. _____69 _____The 'Santa lie' can reduce trust between a parent and a child. _____70 _____It is the creation of false evidence and convincing kids that bad evidence is in fact good evidence that discourages the kind of critical thinking we should be encouraging in children in this era. “The ‘Santa lie' is part of a parenting practice that encourages people to believe what they want to believe,simply because of the psychological reward,”says Johnson. “That's really bad for society in general. ”IV. Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s)of the passage in no more than 60 words. Use your own words as far as possible.Exploring the Appeal of VintageToday,the term“vintage”applies to almost everything. Vintage is more recent than an antique (古董)which is defined as 100 years old or more. It basically means reviving something old- fashioned or filled with memories. For an object to be considered vintage,it must be unique and genuine enough to retain at least some of its original charm.We buy vintage because it creates a sense of personal connection for us:it speaks to our childhood memories and that feels good. We also buy vintage because we're rebels. Vintage is a protest against modern mainstream culture. In an age of technology,buying vintage is a refuge from our fast-paced,high-tech world. We want our children to make the most of their creativity and know how to entertain themselves without electronic gadgets. Ironically,early video games are now considered vintage.Of all the vintage objects,vintage toys are forever attractive for both adults and children. Although some toys have emotional value,others have high market value and are expensive to collect. Vintage toys that were made in small quantities often bring a higher value than those that were mass produced. That means,if you own one of the 2,000 “Peanuts”royal blue beanie baby elephants that were manufactured with a darker blue coat than originally intended,you might have something valuable on your hands. In fact,due to a manufacturer error,this is the most collectible beanie baby around —and worth about f3,000.If you're motivated and feeling lucky,you can find deals on vintage toys by browsing charity shops,secondhand stores,community centers,flea markets and garage sales. You never know what kind of treasures are hiding at the bottom of a mixed box in someone's basement,garage or attic.第Ⅱ卷(共40分)V.

拉姆齐模型与世代交替模型的异同一、拉姆齐模型与世代交替模型的相同点拉姆齐模型(又称RCK 模型）与世代交替模型（又称Diamond 模型)都是现代经济增长理论的基准分析模型.两个模型的主要相同点在于：第一，在这两种基准模型的一般均衡分析框架下,宏观层面的经济增长都具备了各个经济主体追求利益最大化的微观基础，这就使得经济学家能够在动态时间视角以及资源跨期最优配置的设定下对宏观经济增长进行更为深入的研究。

第二，两个模型均放弃了储蓄率外生给定的假设而通过家庭的效用最大化行为，将储蓄率表示为资本存量的函数,以便分析储蓄率的变动情况。

第三，两个模型在求解经济体一般均衡的结果时，都从市场竞争以及中央计划者配置（社会性最优）两个角度审视相应最优化结果是否具有一致性，从而比较并分析市场机制与计划手段的社会福利情况。

第四,两个模型的一般均衡结果中，人均资本存量以及人均消费量（以效率劳动的角度衡量)在长期内的增长率均为零，不存在持续性的增长机制。

二、拉姆齐模型与世代交替模型的区别从两个模型形式上的区别来看,经典的拉姆齐模型假设经济体中个人的寿命是无限的，因此对于家庭效用函数的构建以及效用最大化问题的讨论便从数理角度转化为了无限期连续型最优控制问题；而经典的世代交替模型假设经济体中个人的寿命是有限的，将人的一生简单划分为青年和老年两个阶段，青年阶段通过投入自身要素禀赋获得相应收入并消费,老年阶段则消费青年阶段的储蓄量，经济体每一期都存在着青年人出生、老年人死亡、上一期青年人变成老年人的迭代，因此对于消费者效用最大化行为的刻划便从数理角度转化为了跨期的非线性规划问题。

除了这种形式上的区别之外,两类模型还存在如下两点本质性的差异： 第一，竞争性均衡与社会性最优的关系。

在经典的拉姆齐模型中，竞争性均衡与社会性最优的结果是一致的。

首先考虑社会性最优的情形（计划增长模型），假设存在一个代表经济体中全部民众的善意计划者（中央政府）在既定资源约束下选择最优消费与资本增长路径使得家庭消费效用最大化，则最优选择问题可以表示为如下最优控制问题：0(,)0max :(())..:(),(0)t c k U c t e dt s t k f k c nk k k θ∞-=--=⎰解该最优控制问题,得到家庭最优消费路径为： (())c k cc U c f k n c U cθ=--- 接下来考虑竞争性均衡（分散化决策）的情形。

Robots,while incredibly useful in many aspects of modern life,do come with a set of drawbacks that should be considered when integrating them into various systems and daily routines.ck of Emotional Intelligence:Unlike humans,robots do not possess the ability to understand or respond to emotions.This can lead to a lack of empathy and understanding in situations where emotional intelligence is crucial,such as in healthcare or customer service.2.High Initial Costs:The development,production,and maintenance of robots can be expensive.This high cost can be a barrier for many businesses and individuals,especially when considering the potential return on investment.3.Job Displacement:The increasing use of robots in the workforce can lead to job displacement for humans.This is particularly concerning for lowskilled laborers who may find it difficult to retrain for new jobs in a rapidly evolving job market.4.Dependency on Technology:Overreliance on robots can lead to a loss of human skills and abilities.For example,if robots are used to perform repetitive tasks,humans may lose the dexterity and cognitive skills associated with those tasks.5.Ethical Concerns:The use of robots raises several ethical questions,such as the rights of robots,the potential for misuse in surveillance,and the implications of creating machines that can mimic human behavior.6.Limited Creativity:Robots are programmed to perform specific tasks and follow algorithms.They lack the ability to think creatively or solve problems in ways that are not preprogrammed,which can be a limitation in dynamic and unpredictable environments.7.Technical Failures:Robots,like any technology,can malfunction or fail.This can lead to significant problems,especially in critical applications such as healthcare or transportation,where a robots failure could have serious consequences.8.Security Vulnerabilities:Robots that are connected to networks can be vulnerable to hacking and cyberattacks.This can compromise the safety and security of the systems they operate within.ck of Adaptability:Robots may struggle to adapt to new or unexpected situations. This inflexibility can be a significant drawback in environments that require quickthinking and adaptability.10.Social Isolation:The increased use of robots in social settings can lead to social isolation,as human interaction is reduced.This can have negative effects on mental health and social skills development,especially among children and the elderly. Understanding these potential drawbacks is essential for responsible and ethical use of robotics technology.It is crucial to balance the benefits of automation with the potential risks and challenges to ensure a harmonious integration of robots into society.。

劳瑞模型发展综述城市用地与城市交通的关系既密切又复杂，用地通过产生出行量作用于交通运输系统；反过来，交通运输通过增强可达性作用于用地布局。

用地与交通运输之间的相互影响，国内外许多学者对此作了大量的研究，希望通过数学建模技术描述用地与交通的复杂关系。

劳瑞模型作为一种经典的交通与土地利用模型。

从20世纪60年代提出至今，经过不断的改进和扩展，在世界许多城市得以应用，显示出强大的生命力。

对于劳瑞模型及其发展方面的研究，国内外关于这方面的研究主要是在对原有劳瑞模型提出的基础上，引入其他相关学科的基础理论进行了改进，但其以交通区为单元进行分析的指导思想不变。

主要涉及劳瑞模型的基础理论、改进形式以及在实践中的应用等几个方面。

1、劳瑞模型的提出劳瑞模型是美国交通学者Lowry于1964年，在研究匹兹堡交通规划问题时提出。

它研究封闭城市区域（对象城市区域与外界城市区域不存在人员流动）的前提下，定量描述各土地利用之间的相互作用，是决定住户数和就业人数的分布模型，住户数和就业人数确定各交通小区的土地利用结构。

在对象区域内，该模型将具有一定目的地的土地利用者称为土地利用的活动主体，大致分为基础产业部门；非基础产业部门；住户部门三种。

基础产业部门包括工业、大型贸易公司、中央政府直属机关、大学等，它们作为模型的已知条件给出，而非由对象城市区域的社会、经济规模决定。

非基础产业部门包括商业、服务业地方政府机关、中小学等与居民生活密切相关的部分。

这些部门吸引顾客到市内，其规模即就业人数等依赖于城市区域的人口、经济状况，其选址亦应考虑居民的出行方便，由模型内部计算确定。

住户部门是指就业于基础和非基础产业部门的住户和人口[6]。

基于上述土地利用主体的划分，劳瑞模型建立的基本思路⑴是：各活动主体在城市区域内需要获得用地而从事活动，作为其前提。

一个城市区域可视为区域及国家社会经济体系的子系统。

In our daily lives,discrimination can take many forms and can be based on various factors such as race,gender,age,or social status.Here is an essay on the experience of discrimination in life,highlighting some common scenarios and the impact it can have on individuals.Title:Encountering Discrimination in Everyday LifeIntroduction:Discrimination is a pervasive issue that affects countless individuals across the globe.It is an unjust behavior that stems from prejudice and ignorance,often leading to the unfair treatment of others.This essay delves into personal experiences with discrimination and the broader implications it has on society.Experiencing Racial Discrimination:One of the most common forms of discrimination is racial.It can manifest in subtle ways, such as being overlooked for a job opportunity,or more overtly,through verbal abuse or physical violence.For instance,a person of color might find themselves the target of derogatory comments or stereotypes,which can be deeply hurtful and dehumanizing. Gender Discrimination in the Workplace:Women often face discrimination in professional settings,where they may be paid less than their male counterparts for the same work,or be passed over for promotions despite equal qualifications.This gender bias can be frustrating and demoralizing,as it undermines the principle of equal opportunity.Ageism in Society:Age discrimination is another form of prejudice that affects people of all ages,but is particularly prevalent against the elderly.Older individuals may find themselves marginalized or dismissed based on their age,which can lead to feelings of isolation and a lack of respect.Social Status and Economic Discrimination:People from lower socioeconomic backgrounds often face discrimination based on their financial status.This can result in limited access to quality education,healthcare,and other essential services.The stigma associated with poverty can also lead to social exclusion and a lack of representation in decisionmaking processes.The Impact of Discrimination:The effects of discrimination are farreaching and can lead to a range of negative outcomes,including psychological distress,social isolation,and a reduced quality of life.It can also perpetuate cycles of poverty and inequality,as those who are discriminated against may find it more difficult to access opportunities for social and economic mobility.Overcoming Discrimination:To combat discrimination,it is essential to foster a culture of inclusivity and respect for diversity.This can be achieved through education,awareness campaigns,and legal protections that ensure equal rights for all individuals,regardless of their background.It is also crucial for individuals to stand up against discrimination when they witness it,and to support those who have been affected by it.Conclusion:Discrimination is a complex and multifaceted issue that touches many aspects of life.By understanding the various forms it can take and the impact it has on individuals and society,we can work towards creating a more equitable and just world for everyone.It is through collective action and a commitment to fairness that we can hope to overcome the scourge of discrimination.。

The chart provided offers a comprehensive overview of the population growth trends over the past century. It is clear from the data that there has been a significant increase in the global population, with some regions experiencing more rapid growth than others.Starting from the early 1900s, the world population was relatively stable, with a gradual increase. However, the postWorld War II era saw a sharp rise in population numbers, which can be attributed to advancements in healthcare, improved living conditions, and a decrease in mortality rates.The chart also highlights the disparities between different regions. For instance, while the population in North America and Europe has grown steadily, the most dramatic increase has occurred in Asia and Africa. This can be linked to the higher fertility rates and a larger proportion of the population in their reproductive years in these regions.Furthermore, the chart indicates that the rate of population growth has slowed down in recent decades. This is likely due to a variety of factors, including increased access to education, family planning initiatives, and a shift towards smaller family sizes in many parts of the world.In conclusion, the chart effectively illustrates the dynamic nature of population growth over the past century. It underscores the importance of understanding these trends to inform policy decisions and ensure sustainable development for future generations.。
