You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking the corresponding letter on Answer Sheet2.Take Naps at Work.Apologize to No One[A]In the past two weeks I’ve taken three naps at work,a total of an hour or so of shut-eye while on the clock.And I have no shame or uncertainty about doing it.I couldn’t feel better about it,and my productivity reflects it,too.[B]Sleeping on the job is one of those workplace taboos-like leaving your desk for lunch or taking an afternoon walk-that we’re taught to look down on.If someone naps at2p.m.while the rest of us furiously write memos and respond to emails,surely it must mean they’re slacking off(偷懒).Or so the assumption goes.[C]Restfulness and recharging can take a back seat to the perception and appearance of productivity.It’s easier to stay on a virtual hamster(仓鼠)wheel of activity by immediately responding to every email than it is to measure aggregate productivity over a greater period of time.But a growing field of occupational and psychological research is building the case for restfulness in pursuit of greater productivity.[D]Companies are suffering from tremendous productivity problems because people are stressed out and not recovering from the workday,said Josh Bersin,Principal and Founder of Bersin by Deloitte.“They’re beginning to realize that this is their problem,and they can’t just say to people,‘Here’s a work-life balance course,go teach yourself how to manage your inbox,’”Mr.Bersin said.“It’s way more complicated than that.”[E]To be sure,the ability to nap at work is far from widespread,experts said.Few among us have the luxury of being able to step away for a half-hour snoozefest.But lunch hours and coffee breaks can be great times to duck out,and your increased productivity and alertness will be all the evidence you need to make your case to inquiring bosses.[F]In an ideal world,we’d all solve this problem by unplugging early and getting a good night’s sleep. Here’s our guide on how to do just that.But the next best thing is stealing away for a quick power nap when you’re dragging after lunch.[G]In a study published in Nature Neuroscience,researchers tested subjects on their perceptual performance four times throughout the day.Performance deteriorated with each test,but subjects who took a30-minute nap between tests stopped the deterioration in performance,and those who took a60-minute nap even reversed it.[H]“Naps had the same magnitude of benefits as full nights of sleep if they had a quality of nap.”said Sara Mednick,a co-author of the study and associate professor of psychology at the University of California,Riverside.[I]Dr.Mednick,a sleep researcher and the author of Take a Nap!Change Your Life,said daytime napping can have many of the benefits of overnight sleep,and different types of naps offer specific benefits.[J]For example,Dr.Mednick said a20-to60-minute nap might help with memorization and learning specific bits of information.It’s just long enough to enter stage-two sleep,or non-rapid eye movement(R.E.M.)sleep.[K]After60minutes,you start getting into R.E.M.sleep,most often associated with that deep,dreaming state we all enjoy at night R.E.M.sleep can improve creativity,perceptual processing and highly associativethinking,which allows you to make connections between disparate ideas,Dr.Mednick said.Beyond that,your best bet is a90-minute nap,which will give you a full sleep cycle.[L]Any nap,however,can help with alertness and perception and cut through the general fog that creeps in during the day,experts said.[M]So how did we even arrive at this point where aptitude is inextricably tied(紧密相连)to working long, concentrated hours?Blame technology,but think broader than smartphones and laptops;the real issue is that tech has enabled us to be available at all times.[N]“We went through a period where people were in denial and business leaders were ignoring it,”Mr. Bersin said.“They were assuming that if we give people more tools,more emails,more Slack,more chatter,and we’ll just assume they can figure out how to deal with it all.And I think they’ve woken up to the fact that this is a big problem,and it is affecting productivity,engagement,health,safety,wellness and all sorts of things.”[O]It isn’t just office workers who can benefit from an afternoon siesta(午睡).A2015study published in Current Biology looked at the at the sleeping habits of three hunter-gatherer preindustrial societies in Tanzania, Namibia and Bolivia.[P]“They’re active in the morning,then they get in the shade under the trees and have a sort of quiet time, but they’re not generally napping,”said Jerome Siegel,professor of psychiatry and biobehavioral sciences,and director of the U.C.L.A.Center for Sleep Research,a co-author of the study.“Then they do some work and go to sleep,and they sleep through the night.”[Q]Still,Mr.Siegel said,“the only genuine way to solve daytime sleepiness and fatigue starts the night before with a solid night’s sleep.”The real Holy Grail of restfulness is a regular sleep schedule with ideally seven or eight hours of sleep each night,which experts say is optimal.[R]“Daytime napping certainly does increase alertness,”Mr.Siegel said.“But it’s not as simple as going to the gas station and filling the tank.”[S]He also advises avoiding caffeine late in the day and waking around the same time every morning,even if you can’t get to sleep at the same time every night,This helps acclimate(使适应)your body to your regular wake-up time,regardless of how much sleep you got the night before.[T]So if you’ve made it this far and you’re interested in giving workday naps a try(or just starting to nod off),here’s a quick guide to the perfect nap;Find a quiet,unoccupied space where you won’t be disturbed.Try to make your area as dim as possible(or invest in a sleep mask you can keep in the office).Earplugs might help.too.Aim for around20minutes.Any longer than that and you’re likely to wake up with sleep inertia(睡眠惰性)，which will leave you even groggier(头脑昏沉的)than before.36.Participants’perceptual performance became better after sleeping one hour between tests in an article inNature Neuroscience.37.Jerome Siegel found that only by sleeping soundly through the previous night could people tackle theirweariness during the day.38.Our talent is closely bound to working with concentration for long periods of time because technologymakes us accessible24/7.39.Taking a nap at work is normally regarded as laziness that should be held in contempt and avoided inworkplace.40.Between20to60minutes,people can get into non-REM sleep which may improve memory and learningability according to Dr.Mednick.41.People can doze off at lunch and coffee breaks and defended themselves by saying their improvedproductivity and alertness when bosses investigated their whereabouts.42.The author’s tips on taking a perfect nap involve sleeping place,environment and duration.43.The author believes business leaders are aware that availability at any time due to technology has negativeeffects on every aspect of people’s life.44.The optimal length of a nap was an hour and a half so that people could go through a complete sleep cycle.45.Josh Bersin mentioned the cause of companies’big productivity problems and the solution which needsmore that just employees’efforts.Section CDirections:There are2passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.Every office worker hates meetings.But it’s a strange sort of hate,similar to the hatred of Londoners for the Northern Line,or New Yorkers for tourists who walk too slowly:the dislike is real,yet if the despised thing were to vanish,it’d be like surrendering a piece of your soul.When researchers probed into why people put up with the strain that meetings place on their time and sanity, they found something-those who resent and dread meetings the moat also defend them as a“necessary evil”, sometimes with great passion.True,research suggests that meetings take up vastly more of the average manager’s time than they used to.True,done badly,they’re associated with lower levels of innovation and employee wellbeing(幸福).But that’s just office life,right?It’s not supposed to be fun.That’s why they call it work.Underlying(引起)this attitude is an assumption that’s drummed into us not just as workers but as children, parents and romantic partners;that more communication is always a good thing.So suggestions abound for(大量存在)communicating better in meetings-for example,hold them standing up,so speakers will come to the point more quickly.But even when some companies consider abolishing meetings entirely,the principle that more communication is better isn’t questioned.If anything,it’s reinforced when such firms introduce“flat”management structures,with bosses always available to everyone,plus plenty of electronic distraction.In fact,constant connectivity is disastrous for both job satisfaction and the bottom line.And anyway,once you give it three seconds’thought,isn’t it cleat that more communication frequently isn’t a good thing?Often,the difference between a successful marriage and a second-rate one consists of leaving about three or four things a day unsaid.At work,it’s surely many more than four,though for a different reason;office communication comes at the cost of precisely the kind of focus that’s essential to good work.Yet we’re so accustomed to seeing talking as a source of solutions-for resolving conflicts or finding new ideas-that it’s hard to see when it is the problem.46.What does the author say about meetings?A)Londoners hate them as well as the Northern Line.B)They can help to keep workers’physical and spiritual health.C)Workers might be reluctant to give up them completely.D)New Yorkers dislike meetings more than Londoners.47.What did researchers find about people’s attitude towards meeting?A.Their attitude and behavior are paradoxical.B)People who hate meetings the most are senior insane.C)Those who like meetings might be considered insane.D)More meetings are regarded as a sign of less innovation.48.Why do people think that more communication is always a good thing?A)Because the concept is firmly believed by workers.B)Because everyone loves to communicate with others.C)Because the idea has been instilled into people’s mind.D)Because communication is vital for building relationships.49.What does the author think of the“flat”management structure?A)It forces bosses to frequently contact their employees.B)It helps to soften employees’bottom line of work.C)It is definitely a disaster to employees’job satisfaction.D)It strengthens people’s deeply-rooted notion of communication.50.What is the author’s argument about office communication?A)It is an effective way to solve office conflicts.B)It affects work efficiency in a negative way.C)It should come to a halt at intervals.D)It is useful for workers to find new ideas.Passage TwoQuestions51to55are based on the following passage.The Internet has enabled the spread of information at lightning speed.This information revolution has created tremendous business opportunities for online publishers,but not all of them maintain proper quality-control mechanisms to ensure that only good information is being shared.Instead,many publishers aim simply to make money by whatever means possible,with no regard for the implications for society at large.When selfish publishers set up shops online,the primary goal is to publish as much as possible,often at the cost of quality.In this respect,many publishers start numerous online journals focused on overlapping(重叠的)disciplines—to increase their total number of published papers—and hire young business managers who do not have any experience in either science or publishing.In some cases,online publishers even give up peer review, while still presenting themselves as scientific journals—deception designed to take advantage of scientists who simply want to share their research.If publishers structure their business to make more revenue,it often does harm to their products.When publishers start journals with overlapping domains,in combination with the pressure to publish more studies,this could promote the publication of marginal or even questionable articles.Moreover,publishers with multiple overlapping journals and journals with very narrow specialties(专业)increase the demands on the time and efforts of willing reviewers.With the fact that reviewers are generally not compensated for their time and effort,journal editors are often unable to find enough reviewers to keep up with the increased publication rate.To improve the situation and increase the trust in scientific community,the pressure to publish must be reduced.Funding and promotion decisions should not be based on the number of publications,but on the quality of those publications and a researcher’s long-term productivity and instructions.And that’s just the start.We need additional mechanisms,such as Beall’s list of predatory(掠夺的)publishers, to alert scientists to fake journals and fake articles.In addition,the price for online publication must be controlled and a mechanism must be put in place to honor and reward hard-working reviewers.51.What does the author think of online publishers?A)A small proportion of them can guarantee their publishing quality.B)They have lots of opportunities to renovate their business models.C)Many of them tend to try every means to make a buck.D)Social impact is their first priority when publishing books.52.It can be inferred from the second paragraph that______.A)peer review generally is a criterion to identify academic journalsB)researchers focus their research on the combination of disciplinesC)scientists care about their publications rather than researchD)young business managers are willing to face new challenges53.Why can’t publishers find enough reviewers to review papers?A)Reviewers are pressed for time when reviewing articles.B)Reviewers’gains can’t make up for what they have done.C)Publishers may compel reviewers to accept marginal articles.D)Publishers urge reviewers to increase publication rate rapidly.54.What is the author’s suggestion for online publication?A)More weight should be put on the quantity of publications.B)It is worthwhile to reward diligent reviewers for their effort.C)Fake journals should be reported to a regulatory organization.D)The price of online publication should be lowered greatly.55.What is the main idea of this passage?A)Online publishers should take measures to fight against fake scientific journals.B)Online publishers are pursuing their work efficiency at the cost of quality.C)Online publishers business models are quite likely to harm their publications.D)Online publishers are sacrificing the quality of research articles to make money.PartⅣTranslation(30minutes)Directions:For this part,you are allowed30minutes to translate a passage from Chinese intoEnglish.You should write your answer on Answer Sheet2.春节是中国的传统节日，相当于美国的圣诞节。
英语作文 人口增长
英语作文人口增长Population Growth。
Population growth refers to an increase in the number of people living in a particular area. This phenomenon can occur due to various factors such as birth rates, death rates, immigration, and emigration. In recent years, the global population has been steadily increasing, raising concerns about the potential impact on the environment, economy, and society as a whole.One of the primary reasons for population growth is the decline in death rates. With advancements in medical technology and improved access to healthcare, people are living longer and healthier lives. This has led to a significant decrease in mortality rates, particularly in developing countries. As a result, the overall population has been steadily increasing, putting a strain on available resources and infrastructure.Another contributing factor to population growth ishigh birth rates. In many parts of the world, particularlyin developing countries, large families are still commondue to cultural, religious, and economic reasons. Additionally, lack of access to contraception and family planning services can also contribute to higher birth rates. As a result, the population in these areas continues togrow rapidly, exacerbating issues such as poverty, unemployment, and inadequate healthcare and education services.Immigration also plays a significant role in population growth, particularly in developed countries. People often migrate to more developed nations in search of better opportunities, higher standards of living, and political stability. This influx of migrants can contribute to population growth in the host country, leading to increased competition for jobs, housing, and social services.The implications of population growth are far-reaching and can have a profound impact on the environment, economy, and society. One of the most pressing concerns is thestrain on natural resources, including water, food, and energy. As the population continues to grow, the demand for these resources increases, leading to overexploitation and environmental degradation.Furthermore, population growth can also lead to urbanization, as more people migrate to cities in search of employment and better living conditions. This rapid urbanization can put a strain on infrastructure, leading to overcrowding, traffic congestion, and inadequate housing. Additionally, it can also lead to increased pollution and a decline in air and water quality.From an economic perspective, population growth can have both positive and negative impacts. On one hand, a growing population can lead to increased consumer demand, which can stimulate economic growth and development. However, it can also lead to higher unemployment rates, as the labor force grows at a faster rate than job creation. This can put a strain on social welfare programs and lead to increased income inequality.In conclusion, population growth is a complex and multifaceted issue that requires careful consideration and planning. It is essential to address the underlying factors contributing to population growth, such as high birth rates, immigration, and declining death rates. Additionally,efforts should be made to promote sustainable development, improve access to family planning services, and address the root causes of poverty and inequality. By taking a comprehensive approach to population growth, we can work towards creating a more sustainable and equitable futurefor all.。

人口问题英语作文Population Problem。
The population problem is one of the most pressing issues facing the world today. With the global population reaching over 7 billion people, the strain on resources and the environment is becoming increasingly severe. In this essay, we will explore the causes and effects of the population problem, as well as potential solutions to this critical issue.There are several factors contributing to the population problem. Firstly, advances in medical technology and healthcare have led to a significant decrease in mortality rates, resulting in a higher life expectancy. This means that more people are living longer, leading to an overall increase in the population. Additionally, cultural and societal norms in certain regions encourage large families, further exacerbating the issue. Moreover, lack of access to education and family planning resourcesin developing countries also contribute to rapid population growth.The effects of overpopulation are far-reaching and impactful. The strain on natural resources, such as water, food, and energy, is becoming increasingly severe. This not only leads to scarcity and increased prices, but also contributes to environmental degradation and climate change. Furthermore, overpopulation leads to increased competition for jobs, housing, and other essential resources, leadingto social and economic instability. Additionally, overcrowding in urban areas can lead to increased pollution, inadequate infrastructure, and decreased quality of lifefor residents.In order to address the population problem, it iscrucial to implement effective solutions. Firstly, accessto education and family planning resources must be improved in developing countries. By empowering individuals with knowledge and resources, they can make informed decisions about family size and reproductive health. Additionally, governments and organizations should invest in sustainabledevelopment and renewable energy sources to alleviate the strain on resources. Furthermore, policies that promote smaller families and responsible population growth should be implemented to address the issue at its root.In conclusion, the population problem is a critical issue that requires immediate attention and action. By addressing the causes and effects of overpopulation and implementing effective solutions, we can work towards a more sustainable and balanced future for our planet. It is imperative that individuals, governments, and organizations work together to address this pressing issue and create a better world for future generations.。
社会变化英语作文词汇
社会变化英语作文词汇The world we live in is constantly evolving and transforming. The pace of change has accelerated in recent decades due to rapid technological advancements and globalization. These societal changes have had a profound impact on our lives in various ways. From the way we communicate and work to the way we entertain ourselves and interact with one another everything has been affected by the tides of changeOne of the most significant societal changes in recent times has been the rise of digital technology. The internet has revolutionized the way we access information and communicate with others. Social media platforms have become an integral part of our daily lives allowing us to connect with friends family and strangers across the globe with just a few taps on our smartphones. This has fundamentally altered the way we socialize and build relationshipsThe proliferation of smartphones and other mobile devices has also changed the way we consume media and entertainment. Streaming services have largely replaced traditional cable television allowing usto watch our favorite shows and movies on demand. Similarly the music industry has been transformed by the rise of digital music platforms like Spotify and Apple Music. These changes have provided us with greater convenience and choice but have also had some negative consequencesFor instance the constant use of digital devices has been linked to increased levels of anxiety and depression particularly among young people. The constant need to check our phones and keep up with social media can lead to feelings of FOMO fear of missing out and a sense of inadequacy when comparing ourselves to the carefully curated lives of others online. This has led to growing concerns about the impact of technology on mental health and wellbeingAnother major societal change has been the shift towards a more globalized world. Advances in transportation and communication technologies have made it easier than ever before to connect with people and access information from all corners of the globe. This has brought about greater cultural exchange and understanding but has also led to some challengesThe increasing diversity of our societies has led to tensions and conflicts as people grapple with issues of identity integration and belonging. There has been a rise in nationalist and populist movements in many parts of the world as some people feelthreatened by the pace of change and long for a return to a more homogeneous past. This has contributed to growing political polarization and a breakdown in social cohesion in many countriesAt the same time globalization has also led to the spread of new ideas and values particularly around issues of human rights gender equality and environmental protection. Movements like #MeToo and Black Lives Matter have gained traction globally as people have become more aware of systemic inequalities and injustices. This has led to important conversations and changes but has also faced significant backlash from those who feel their traditional power and privilege are being threatenedAnother major societal change has been the aging of the global population. In many developed countries the population is getting older as people live longer and birth rates decline. This has created new challenges for governments and healthcare systems as they grapple with the needs of an aging population. It has also led to shifts in the workforce and economy as the ratio of working-age adults to retirees changesAt the same time the global population as a whole is becoming younger with a growing number of young people particularly in developing countries. This demographic shift has the potential to bring about significant social and economic changes as youngergenerations demand more opportunities for education employment and political participation. However it also raises concerns about issues like youth unemployment and the ability of governments to meet the needs of a rapidly growing young populationFinally one of the most pressing societal changes of our time is the growing awareness of the urgent need to address climate change and environmental degradation. The devastating impacts of global warming extreme weather events and environmental destruction have become increasingly visible and impossible to ignore. This has led to a groundswell of activism particularly among young people demanding urgent action from governments and corporations to transition to more sustainable practicesOverall the societal changes we are witnessing are complex multifaceted and often contradictory. They present both challenges and opportunities as we grapple with issues of identity technology globalization demographics and the environment. Navigating these changes will require us to be adaptable creative and willing to work together across borders and divides. It is a daunting task but also an essential one if we are to build a more just equitable and sustainable future for all。
英语2024年1月六级作文人口老龄化
英语2024年1月六级作文人口老龄化With the advancement of medical technology and improvements in living conditions, the global population is aging at an unprecedented rate. The phenomenon of population aging has become a significant social issue in many countries around the world.There are several reasons contributing to the population aging trend. Firstly, declining birth rates mean that there are fewer young people to support the growing number of elderly individuals. Additionally, advancements in healthcare have led to longer life expectancy, resulting in a larger elderly population. Furthermore, changes in lifestyle and family structures have also played a role in the aging population, with smaller family sizes and increased urbanization leading to fewer children to care for aging parents.The implications of population aging are far-reaching and multifaceted. There are concerns about the economic impact, as a shrinking workforce may lead to labor shortages and increased pressure on social welfare systems. Health care systems will also face challenges in providing quality care for the elderly population. Moreover, theremay be social implications, such as changes in family dynamics and increased demand for elderly care services.In response to the challenges posed by population aging, governments and societies need to develop policies and programs that address the needs of the aging population. This may include measures to support elderly individuals, promote healthy aging, and create a more age-friendly environment. By addressing the challenges of population aging proactively, societies can better prepare for the demographic shift and ensure the well-being of their aging populations.中文翻译：随着医疗技术的进步和生活条件的改善，全球人口正以前所未有的速度老龄化。

老年人的比例高于年轻人英文作文
老年人的比例高于年轻人英文作文全文共3篇示例，供读者参考篇1The proportion of elderly people in the global population is steadily increasing, with more and more countries facing the reality of an aging population. This demographic trend has significant implications for various aspects of society, including healthcare, social services, and the economy.There are several reasons for the rising proportion of elderly people compared to younger individuals. One key factor is the increase in life expectancy due to advancements in healthcare and living standards. As a result, people are living longer lives, leading to a larger proportion of the population being in the older age group. Additionally, declining birth rates in many countries contribute to the aging population, as there are fewer young people to balance out the number of elderly individuals.The aging population presents challenges and opportunities for society as a whole. On the one hand, there is an increased demand for healthcare services, long-term care facilities, and supportive services for the elderly. This places a strain onhealthcare systems and social services, as they need to cater to the needs of a larger number of elderly individuals. Furthermore, there is a growing need for policies and programs that address the unique needs of older adults, such as pension schemes, retirement savings, and age-friendly infrastructure.On the other hand, the aging population also presents opportunities for economic growth and innovation. Older adults are a valuable resource with a wealth of knowledge, skills, and experience that can contribute to the economy in various ways. For example, many older adults are choosing to work past retirement age, either in part-time roles or as consultants, sharing their expertise with younger generations. This not only benefits the economy but also helps to bridge the generation gap and foster intergenerational solidarity.In addition to the economic impact, the aging population also has social implications. As more and more older adults require care and support, there is a growing need for family members and caregivers to take on these responsibilities. This can place a significant burden on families, especially those with multiple generations to support. It also highlights the importance of creating age-friendly communities that provide accessible services and support for the elderly.In conclusion, the rising proportion of elderly people compared to younger individuals is a global demographic trend that has far-reaching implications for society. While it presents challenges in terms of healthcare, social services, and family responsibilities, it also offers opportunities for economic growth and intergenerational collaboration. By addressing the needs of the aging population and fostering age-friendly policies and programs, societies can ensure that older adults can age with dignity and continue to contribute to the community in meaningful ways.篇2The proportion of elderly people is growing at a faster rate than that of younger people. This trend is becoming increasingly prevalent around the world due to several factors such as increased life expectancy, declining birth rates, and improvements in healthcare. In this essay, we will explore the reasons behind this demographic shift, its implications, and potential solutions to address the challenges associated with an aging population.One of the primary reasons why the proportion of elderly people is increasing is the significant improvement in life expectancy over the past century. Advances in medicaltechnology, better healthcare services, and overall improvements in living conditions have all contributed to people living longer lives. As a result, the number of elderly individuals is growing at a faster pace than that of younger generations.Another factor contributing to the rise in the elderly population is the declining birth rates in many countries. With more couples choosing to have fewer children or delaying starting a family, the overall population growth rate has slowed down. This, coupled with increasing life expectancy, has led to a higher proportion of elderly individuals in many societies.The implications of this demographic shift are far-reaching and pose significant challenges for governments, healthcare systems, and social services. As the number of elderly people increases, there will be a greater demand for healthcare services, long-term care facilities, and social security programs. This can put a strain on resources and lead to budgetary constraints for governments.Moreover, an aging population can also have economic implications, such as a shrinking workforce and a lower ratio of working-age individuals to support retirees. This can impact productivity levels, economic growth, and the overall welfare of society. Additionally, there may be increased pressure on socialservices, such as pension systems, as more elderly individuals require financial support in their retirement years.To address the challenges associated with an aging population, governments and policymakers need to implement strategies to support the elderly, promote healthy aging, and ensure the sustainability of social welfare programs. This can include investing in healthcare services, promoting active aging initiatives, and implementing policies to support older individuals in the workforce.Furthermore, there is a need to foster intergenerational solidarity and support networks to ensure that the needs of both younger and older generations are met. Encouraging collaboration and cooperation between different age groups can help build a more inclusive and supportive society for people of all ages.In conclusion, the proportion of elderly people is growing at a faster rate than that of younger people due to factors such as increasing life expectancy and declining birth rates. This demographic shift poses challenges for governments, healthcare systems, and social services, but with strategic planning and proactive measures, it is possible to address the implications ofan aging population and create a more age-friendly society.归纳总结篇3The number of elderly population is steadily increasing in many countries around the world. This trend is largely attributed to advancements in healthcare, better living conditions, and increased life expectancy. As a result, the proportion of elderly individuals is surpassing that of younger generations in many societies.One of the primary factors contributing to the higher proportion of elderly people is the aging of the Baby Boomer generation. This generation, which refers to individuals born between 1946 and 1964, is now reaching retirement age in large numbers. As a result, there has been a significant surge in the number of elderly individuals in the population. The Baby Boomer generation is also living longer than previous generations, thanks to improvements in healthcare and lifestyle choices.Another factor that is contributing to the increasing proportion of elderly individuals is declining birth rates. In many developed countries, birth rates have been on the decline fordecades. This means that there are fewer young people entering the workforce and contributing to the economy. At the same time, the elderly population is growing, putting a strain on social welfare programs and healthcare systems.The implications of having a higher proportion of elderly individuals in the population are far-reaching. For one, there are concerns about the sustainability of social security and healthcare systems. With more elderly individuals relying on these programs, there may be fewer resources available for younger generations. This could lead to increased taxes, decreased benefits, or a combination of both.Additionally, the increase in the elderly population is also raising questions about intergenerational equity. With a larger proportion of elderly individuals, there may be greater competition for resources between generations. Younger individuals may feel the effects of this competition in terms of access to education, employment, and housing.Furthermore, the higher proportion of elderly individuals is also posing challenges in terms of healthcare and long-term care. As people age, they are more likely to develop chronic health conditions and require additional medical care. This places astrain on healthcare systems and can lead to increased healthcare costs for individuals and governments alike.In conclusion, the proportion of elderly individuals is on the rise in many societies around the world. This trend is a result of various factors, including the aging of the Baby Boomer generation, declining birth rates, and increased life expectancy. While this demographic shift presents challenges in terms of social welfare, healthcare, and intergenerational equity, it also highlights the importance of addressing the needs of an aging population. By developing policies and programs that support elderly individuals and promote healthy aging, societies can better prepare for the future.。

The global population is living longer，and getting older，阅读理解答案
The global population is living longer，and getting older，which presents new challenges. “The question becomes：who will take care
of everyone While people will always be the best caregivers for people，there just aren’t enough people. That’s where robot17教育网：ic technology can really make a difference,” says Professor Maja Mataric at the University of Southern California.
Her group is developing robots to work with stroke (中风) patients
and elderly people. The research team has found that people react
well to a robot gym instructor，and seem to get less frustrated with
it than with instructions given on a computer screen. The robot can
act as a perfect trainer，with infinite(极大的) patience.
“People say things like ‘I prefer this robot to my husband！Can I take it home’” according to Professor Mataric. “In fact there’s a really important point here. As we creat e these care giving technologies，we’re helping not only the people that need the care，but also the people caring for them. We can give them a break，and help them avoid burnout.”
People are going to have to like，and importantly trust robots before they welcome them into their homes，and several groups around the world are working on making it easier to communicate with them.
Much of human communication takes place through body language. Gestures， eye contact , and concepts of personal space are all
things that robots are being taught. In learning about how people interact(互动) with machines，researchers are also discovering new roles for robots in our lives. Robots can communicate with humans in ways that other technologies can not.
“If someone finds the robot to be more persuasive and more reliable，that’s going to affect how they interact with it,” says Dr Cynthia Breazeal, director of the Personal Robots Group at the Massachusetts
Institute of Technology. “We can now start to think about fields where it’s the social interaction，which is the main means by which a robot helps someone.” Dr Breazeal says that means robots could be used in education，learning，and health care，where social support is important.
9．Professor Maja Mataric mainly focused on robots’ function of
________.
A．teaching B．exploring
C．making things D．giving care
10．Why can robots be wonderful trainers in the gym
A．Because they are more clever.
B．Because they give correct instructions.
C．Because they cost less money.
D．Because they are more patient.
11．The underlined word “burnout” in Paragraph 3 probably means “________”．
A．feeling tired B．feeling angry
C．getting hurt D．becoming disappointed
12．The scientists are presently working hard to help robots .
A．to use less electricity B．to communicate better
C．to react more quickly D．to have more functions
答案解析：
【答案】
9．D
10．D
11．A。
