新视野大学英语第三册课文翻译Unit1 AMy brother, Jimmy, did not get enough oxygen during a difficult delivery, leaving him with brain damage, and two years later I was born. Since then, my life revolved around my brother’s. Accompanying my growing up was always “go out and play and take your brother with you”. I couldn’t go anywhere without him, so I urged the neighborhood kids to come to my house for some out-of-control kid-centered fun我哥哥吉米出生时遇上难产，因为缺氧导致大脑受损。

两年后，我出生了.从此以后，我的生活便围绕我哥哥转。

伴随我成长的，是“到外面去玩，把你哥哥也带上。

”不带上他，我是哪里也去不了的。

因此，我怂恿邻居的孩子到我家来，尽情地玩孩子们玩的游戏。

My father, a saint, simply held the house together with his patience and understanding.I was in charge outside where I administered justice by tracking down the parents of the kids who picked on my brother, and telling on them.我母亲教吉米学习日常自理，比如刷牙或系皮带什么的.我父亲宅心仁厚，他的耐心和理解使一家人心贴着心。

有关企业的社会责任与担当的英语作文全文共3篇示例，供读者参考篇1Corporate Social Responsibility and Accountability: A Student's PerspectiveAs a student living in the modern age, I have grown increasingly aware of the significant role that corporations play in shaping our society and the world around us. These business entities, with their vast resources and global reach, wield immense power and influence. However, with great power comes great responsibility, and it is imperative that corporations recognize and embrace their social and ethical obligations.The concept of corporate social responsibility (CSR) has gained prominence in recent decades, highlighting the notion that companies should not solely focus on maximizing profits but also consider their impact on society, the environment, and various stakeholders. CSR encompasses a wide range of practices, including responsible labor practices, environmental stewardship, ethical business conduct, and community involvement.One of the most pressing issues surrounding corporate social responsibility is the treatment of employees. Corporations have a moral and ethical duty to provide fair wages, safe working conditions, and opportunities for growth and development. Unfortunately, numerous cases of labor exploitation, sweatshop practices, and inadequate worker protections have tarnished the reputation of many companies, particularly those operating in developing nations. It is crucial that corporations prioritize the well-being of their workforce, not only for ethical reasons but also because a motivated and valued workforce contributes to long-term business success.Environmental sustainability is another critical aspect of corporate social responsibility. The impact of human activities on the planet has become increasingly apparent, with issues such as climate change, resource depletion, and pollution posing severe threats to our collective future. Corporations, as major contributors to these environmental challenges, must take decisive action to reduce their ecological footprint. This can involve adopting clean and renewable energy sources, implementing waste reduction and recycling initiatives, and investing in environmentally friendly technologies and practices.Furthermore, corporations must uphold ethical business practices and maintain transparency in their operations. Engaging in corruption, bribery, or other unethical conduct not only undermines the integrity of the company but also erodes public trust and harms the broader society. Companies should strive for transparency in their financial reporting, supply chain management, and decision-making processes, allowing stakeholders to hold them accountable.Beyond these core responsibilities, corporations can also make a positive impact by actively engaging in philanthropic and community development initiatives. Supporting local educational programs, funding healthcare initiatives, and contributing to disaster relief efforts are just a few examples of how companies can give back to the communities in which they operate. Such efforts not only benefit society篇2Corporate Social Responsibility and Accountability: A Call for Ethical Business PracticesAs a student navigating the complexities of today's business landscape, I find myself increasingly concerned about the role corporations play in shaping our society. While the pursuit ofprofit has long been the driving force behind many business endeavors, we must acknowledge that corporations wield immense power and influence, impacting not only their shareholders but also the communities they operate in and the planet we call home.The concept of corporate social responsibility (CSR) has gained significant traction in recent years, recognizing that businesses have a moral and ethical obligation to consider their impact on society and the environment. However, mere lip service to CSR is not enough; true accountability and tangible actions are paramount.At its core, CSR should be rooted in a genuine commitment to ethical practices that prioritize the well-being of stakeholders, including employees, consumers, and the broader community. This encompasses fair labor practices, responsible supply chain management, environmental stewardship, and a dedication to transparency and good governance.One of the most pressing issues in the realm of CSR is the treatment of workers. Far too often, we hear harrowing tales of exploitative labor conditions, unfair wages, and a blatant disregard for basic human rights. It is incumbent upon corporations to ensure that their employees, as well as thoseemployed by their suppliers and partners, are treated with dignity and respect. Fair compensation, safe working environments, and opportunities for growth and development should be non-negotiable standards.Moreover, corporations must take active steps to minimize their environmental footprint and contribute to the global efforts to combat climate change. The relentless pursuit of profit at the expense of our planet's well-being is not only short-sighted but also a grave threat to our collective future. Embracing sustainable practices, investing in renewable energy sources, and adopting circular economy principles should be prioritized as critical components of CSR strategies.Beyond environmental concerns, corporations also bear a responsibility to uplift the communities in which they operate. This can manifest in various forms, such as supporting local initiatives, investing in educational programs, and contributing to infrastructure development. By actively engaging with and empowering local communities, corporations can foster goodwill, strengthen their social license to operate, and create shared value.Underpinning all these efforts should be a commitment to transparency and accountability. Corporations must be willing toopenly disclose their practices, engage in meaningful stakeholder dialogue, and be held accountable for their actions. Greenwashing and empty promises are no longer acceptable; tangible progress and measurable impact should be the benchmarks against which corporations are evaluated.As future business leaders and decision-makers, we have a profound responsibility to reshape the narrative surrounding corporate social responsibility. We must challenge the notion that profit maximization should come at the expense of ethical considerations and societal well-being. Instead, we should embrace a mindset that recognizes the interdependence between business success and the health of our communities and planet.Integrating CSR principles into business education is crucial in cultivating a generation of leaders who are equipped to navigate the complex landscape of ethical decision-making. By exposing students to case studies, best practices, and thereal-world implications of corporate actions, we can instill a deeper understanding of the importance of responsible and sustainable business practices.Furthermore, we must actively engage with corporations, holding them accountable for their actions and demandinggreater transparency and accountability. By exercising our collective voice as consumers, investors, and members of society, we can exert pressure on companies to prioritize ethical considerations and align their practices with the greater good.Ultimately, the pursuit of corporate social responsibility and accountability is not merely a noble endeavor; it is a moral imperative in an increasingly interconnected andresource-constrained world. By embracing ethical business practices, corporations can not only mitigate their negative impacts but also contribute positively to the well-being of society and the planet.As students and future leaders, it is our duty to challenge the status quo, to question the practices that prioritize short-term gains over long-term sustainability, and to advocate for a more responsible and accountable business ecosystem. Only by holding corporations to higher standards and demanding genuine commitment to ethical and sustainable practices can we create a world where business success is harmoniously intertwined with social and environmental progress.In conclusion, corporate social responsibility and accountability are not mere buzzwords or marketing ploys; they represent a fundamental shift in how we perceive the role ofbusinesses in our society. By embracing ethical practices, prioritizing stakeholder well-being, and demonstrating a genuine commitment to environmental stewardship and community empowerment, corporations can not only enhance their reputation but also contribute to the creation of a more just, equitable, and sustainable world. It is up to us, as students and future leaders, to shape this narrative and ensure that the pursuit of profit is aligned with the greater good.篇3Corporate Social Responsibility and Accountability: An Imperative for BusinessesIn today's increasingly interconnected world, the role and impact of corporations extend far beyond their balance sheets and profit margins. As students pursuing careers in various fields, it is crucial for us to understand the concept of corporate social responsibility (CSR) and the accountability that comes with it. Businesses are no longer isolated entities solely focused on maximizing shareholder wealth; they are integral components of the communities they operate in and have a profound influence on the lives of countless individuals.At its core, corporate social responsibility encompasses the ethical and sustainable practices that companies adopt to address their environmental, social, and economic impacts. It is a recognition that businesses are not merely profit-driven machines but also moral agents with obligations to society. By embracing CSR, companies can contribute to the greater good, foster positive change, and build trust with their stakeholders, including customers, employees, and the communities they serve.One of the most pressing issues that businesses must tackle is environmental sustainability. The consequences of climate change, resource depletion, and pollution are becoming increasingly evident, and corporations have a significant role to play in mitigating these challenges. Responsible companies are adopting eco-friendly practices, such as reducing their carbon footprint, implementing energy-efficient processes, and embracing circular economy models that minimize waste and promote recycling.Beyond environmental concerns, CSR also encompasses social and humanitarian aspects. Companies that prioritize social responsibility strive to uphold human rights, provide fair labor practices, and contribute to the development of localcommunities. This can involve initiatives such as supporting educational programs, investing in healthcare facilities, and promoting gender equality and diversity within their workforce.Furthermore, corporate accountability is intrinsically linked to social responsibility. Companies must be transparent about their operations, ethical conduct, and the impacts they have on society. This transparency fosters trust and allows stakeholders to hold businesses accountable for their actions. Regular reporting, third-party audits, and open dialogue with communities and advocacy groups are essential components of corporate accountability.It is important to note that embracing CSR and accountability is not merely a matter of altruism or public relations; it is a strategic imperative for businesses in the long run. Companies that prioritize sustainability and social responsibility are often better positioned to attract and retain top talent, build customer loyalty, and maintain a positive reputation. Moreover, by proactively addressing societal challenges, businesses can mitigate risks, enhance their resilience, and capitalize on opportunities in emerging markets and sectors.As students, we have the opportunity to shape the future of business practices. By studying and understanding the principles of corporate social responsibility and accountability, we can prepare ourselves to become ethical and socially conscious leaders in our respective fields. Whether we pursue careers in finance, marketing, operations, or any other domain, we can advocate for responsible and sustainable practices within our organizations.Moreover, as consumers and citizens, we have the power to influence corporate behavior through our choices and collective voice. By supporting companies that prioritize CSR and holding those that fall short accountable, we can drive positive change and create a business landscape that prioritizes not only profit but also ethical and sustainable practices.In conclusion, corporate social responsibility and accountability are no longer optional pursuits for businesses; they are fundamental imperatives in today's interconnected and socially conscious world. As future professionals and leaders, it is our responsibility to understand and champion these concepts, ensuring that businesses contribute positively to society while maintaining ethical and sustainable practices. By embracing CSR and accountability, we can create a future where corporationsare not only drivers of economic growth but also catalysts for positive social and environmental change.。

第十章恢复重建理论 (1)第一节灾后恢复重建概述 (1)第二节最小补偿投资 (2)第三节灾后恢复重建索洛模型 (10)第十章恢复重建理论第一节灾后恢复重建概述一、恢复的概念恢复是由英文单词recovery翻译而来，从其基本过程来看，相当于汉语中的恢复重建。

国际减灾战略（ISDR）把恢复定义为：复原并尽可能地改进受灾害影响社区的设施、生计和生存条件，包括努力减轻与灾害风险有关的因素。

美国在《全国突发事件管理系统》中，对恢复的释义是：“制定、协调和实施服务和现场复原预案，重建政府运转和服务功能，实施对个人、私人部门、非政府和公共的援助项目以提供住房和促进复原，对受影响的人们提供长期的关爱和治疗，以及实施社会、政治、环境和经济恢复的其它措施，评估突发事件以汲取教训，完成事件报告，主动采取措施减轻未来突发事件的后果。

总结美国的恢复概念，就是对遭到突发事件破坏的服务设施和现场按照预案复原，对受影响的个人和组织实施援助项目。

恢复的内容不仅包括各种设施，也包括经济、环境、甚至心理状态。

具体来说，恢复包括针对灾难造成的物质和社会两个层面的损失。

物质层面有：基础设施的破坏，企业财产损失、家庭财产损失等等；社会层面有：人员伤亡、经济破坏、心理创伤、环境破坏等等。

但是，并不是每一个层面的每一项损失都是能够弥补或恢复的，比如人员伤亡；即使能够恢复的方面和内容，也不一定能够恢复到灾前的程度，比如经济状况。

二、恢复的类别美国公共安全管理部门根据恢复行动的作用将恢复分为短期和长期两类。

每一类恢复都有各自不同的内容。

（1）短期恢复在应急响应过程中，应对者必须采取一些紧急措施，恢复受到破坏各种机构和设施的基本功能，并且采取保护措施，避免对它们造成进一步的破坏，这些行动就是短期恢复行动，这些行动过程就是短期恢复。

在应急管理周期的四个阶段中，短期恢复同应对有所重叠，有时候二者难以截然分开。

一般来说，应对侧重的是救援，短期恢复侧重的是对设施功能的恢复。
