People wonder how they will pay debts and how they can grow rapidly as they did in the past in an era of deglobalisation(去全球化).The freshest of many answers to this issue is the fast-spreading digital revolution. The digital revolution is already as progressive in emerging economies as developed ones. Among the top 30 nations by income from digital services as a share of gross domestic product(GDP)，16 are in the emerging world. Indonesia，for example，is further advanced by this measure than France or Canada. And since 2017，digital income has been growing in emerging countries at an average annual pace of 26 percent, compared with 11 percent in the developed ones.How can it be that poorer nations are adopting common digital technologies faster than the rich? One explanation is habit and its absence. In societies filled with physical stores and services，customers are often comfortable with them and slow to abandon the providers. In countries where people have difficulty even finding a bank or a doctor，they will jump at the first digital option that comes along. Outsiders have a hard time grasping the impact digital services can have on underserved(服务不足的) populations. Nations lacking in schools，hospitals and banks can quickly bridge these gaps by establishing online services. Though only 5 percent of Kenyans carry credit cards，more than 70 percent have access to digital banking.It’s early days，too. As economist Carlota Perez has shown，tech revolutions last a long time. Innovations like the car and the steam engine were still transforming economies half a century later. Now，the fading era of globalisation will limit the number of emerging markets，but the era of rapid digitisation has only just begun. This offers many developing economies a revolutionary new path to catch up with the living standards of the developed world.1．What can we know about the digital revolution?A．It increases people’s debts in deglobalisation.B．It prevents emerging economy from developing.C．It advances in emerging and developed economies.D．It develops most rapidly in Indonesia in terms of GDP.2．Where are people more willing to accept digital services?A．In economies lacking in online services.B．In countries short of basic physical facilities.C．In nations with adequate stores and services.D．In societies easy to access doctors and banks.3．What does the author think of the future of digitisation?A．Stable. B．Hopeful.C．Depressing. D．Challenging.4．What’s the main idea of the text?A．Digital technology saves emerging economies.B．Deglobalisation limits technology revolutions.C．Emerging economies struggle in the pandemic.D．Digital revolution grows better in globalisation.【语篇解读】本文是一篇说明文。文章主要说明了数字技术拯救了新兴经济体。1．C　细节理解题。根据第二段中的“The digital revolution is already as progressive in emerging economies as developed ones(数字革命在新兴经济体已经和发达经济体一样进步). ”可知，数字革命在新兴经济体和发达经济体中一样进步。故选C项。2．B　细节理解题。根据第三段中的“In countries where people have difficulty even finding a bank or a doctor, they will jump at the first digital option that comes along. Outsiders have a hard time grasping the impact digital services can have on underserved(服务不足的) populations. Nations lacking in schools, hospitals and banks can quickly bridge these gaps by establishing online services. Though only 5 percent of Kenyans carry credit cards, more than 70 percent have access to digital banking(在一些国家，人们甚至很难找到银行或医生，他们会欣然接受出现的第一个数字化选择结果。局外人很难理解数字服务对服务不足人群的影响。缺乏学校、医院和银行的国家可以通过建立在线服务迅速弥合这些差距。尽管只有5%的肯尼亚人持有信用卡，但超过70%的人可以使用数字银行). ”可知，在缺乏基本物质设施的国家的人们更愿意接受数字服务。故选B项。3．B　推理判断题。根据最后一段中的“Now, the fading era of globalisation will limit the number of emerging markets, but the era of rapid digitisation has only just begun. This offers many developing economies a revolutionary new path to catch up with the living standards of the developed world(如今，全球化渐行渐远的时代将限制新兴市场的数量，但快速数字化的时代才刚刚开始。这为许多发展中经济体提供了一条革命性的新道路，以赶上发达国家的生活水平). ”推知，作者认为数字化的未来是有希望的。故选B项。4．A　主旨大意题。根据第一段“Emerging economies struggled to grow through the 2010s and pessimism covers them now. People wonder how they will pay debts and how they can grow rapidly as they did in the past in an era of deglobalisation(去全球化)(新兴经济体在21世纪的头十年曾艰难增长，如今悲观情绪笼罩着它们。人们想知道，他们将如何偿还债务，如何像过去在去全球化时代那样快速增长). ”和第二段中的“The freshest of many answers to this issue is the fast-spreading digital revolution(对于这个问题，许多答案中最新的是迅速传播的数字革命). ”可知，文章主要是关于数字技术拯救了新兴经济体。故选A项。Ⅱ．七选五　I know that facing uncertainty at work can be stressful，particularly in the current economic climate.

Often employers consider the impact layoffs will have on customer relations(接下来，采取措施确保你被客户视为至关重要的人。雇主通常会考虑裁员对客户关系的影响). ”以及下文“However, it may leave a lasting impression on management and colleagues who may be very helpful in your future career(然而，这可能会给管理层和同事留下深刻的印象，他们可能会对你未来的职业生涯有很大的帮助). ”可知，此处承接上文，说明“采取措施确保你被客户视为至关重要的人”这一做法对避免裁员的不一定有用。下文与此处构成转折，指出这可能会给管理层和同事留下深刻的印象，他们可能会对你未来的职业生涯有很大的帮助。E项“当然，这些措施不一定能避免裁员。”符合语境。故选E项。4．D　根据下文的“To prepare for a layoff, take practical steps, such as updating your resume(简历) and profile to highlight any promotions, new skills, projects, and educational achievements. Make use of your network on the job-searching App and other virtual platforms to connect with people in your field(为被解雇做好准备，采取切实可行的措施，比如，更新你的简历和简介，突出任何晋升、新技能、项目和教育成就。利用你在求职软件和其他虚拟平台上的人际网络与你所在领域的人建立联系). ”可知，下文提到为被解雇做好准备，即做好最坏的打算。D项“做最好的打算，做最坏的打算。”符合语境。故选D项。5．A　根据上文的“Financial preparations are also strongly advised. Review your budget and cut it where you can(还强烈建议做好财务准备。回顾你的预算，在你能削减的地方削减). ”可知，上文提到削减开支，即增加储蓄。A项“它可以让你增加储蓄。”符合语境。故选A项。
