Balance profit and business ethics
Business Ethics
▪ Business ethics means written and unwritten codes of moral standards that are critical to the current activities and future aspirations of a business organization. They can differ from one company to another because of differences in cultural perspectives, operational structures and strategic orientations. The guiding framework of business ethics exists all levels of the organization. It is about having the wisdom to determine the difference between right actions and wrong decisions.
Para 2
▪ Free enterprise is still the best economic system for the country as a whole. Under the free enterprise framework, companies develop products and services that people want and that benefit society.
学术英语 Unit 2 课文翻译
《业务营销化》1 问街上一般的人什么是营销时，他们会告诉你那大概就是“卖东西的”。
这从根本上说是正确的，但营销不是简单的销售行为，而是怎样做成的销售。
我们都被全天候不间断营销所围绕，而我们每一个人都已经以我们自己的方式成了一名营销人。
2 专家是怎么定义营销的呢根据美国市场营销协会，市场营销是一种组织职能，是为组织自身及利益相关者（stakeholders n. 利益相关者；股东）而创造、传播、传递客户价值，管理客户关系的一系列过程。
3 根据世界市场营销协会对营销的定义，“核心的经营理念是指导通过交换来识别和满足个人和组织需要的过程，从而为各方创造出众的价值。
”4 最后，英国特许营销学会说，“营销是有利地识别，预测，和满足顾客需求的管理过程”。
5 如果我们只是看这三个定义的共性，我们可以看出，营销本质上（in essence）是：a)发现和给顾客他们所想要的和需要的东西， b)通过做这些来获利。
4Ps或5Ps营销策略6 密歇根州立大学（Michigan State University）的杰罗姆·麦卡锡（Jerome McCarthy）教授在20世纪50年代写了一本书并且定义了4Ps营销策略，包括产品、渠道、价格和促销。
这本书为这个星球上最古老的专业提供了一个清晰的结构，而这个结构成为市场营销的定义。
7 为了更好地理解营销，你应该有你自己对术语的定义。
例如，我认为营销是对产品的价格、分配、促销以及人员进行控制，满足顾客以获得利益。
控制是个充满感情的词语，尤其在我们谈及控制人的时候。
无论怎样，控制是很重要的，因为作为一名营销人员，我要控制市场营销的每一个工具并且操纵它们来使市场的影响力达到最大化。
8 作为一名营销经理，我控制一个产品的形象、味道和触感。
我控制我的产品应该要价多少。
我在促销工具中操纵工具，希望吸引（enticing）消费者购买我的产品。
下面便是被麦卡锡强调的4Ps营销策略。
此外，我们加入了第五个P：人。

学术综合英语unit2学术综合英语Unit 2是关于学术写作的单元。
学术写作是一种特殊的写作风格，用于表达学术观点、研究结果和学术论证。
在这个单元中，我们将学习如何撰写学术论文、报告和研究文章。
首先，学术写作的目的是传达清晰、准确和可靠的信息。
在写作过程中，我们需要注意语言的准确性和逻辑性，避免使用模糊或不确定的词语。
我们应该使用学术术语和专业词汇来确保文章的专业性和可读性。
其次，学术写作需要遵循一定的结构和组织。
一篇学术论文通常包括引言、方法、结果和讨论等部分。
在引言中，我们介绍研究背景和目的；在方法部分，我们描述研究设计和数据收集方法；在结果部分，我们呈现实验结果和数据分析；在讨论部分，我们对结果进行解释和讨论。
这种结构有助于读者理解和跟随我们的论证过程。
此外，学术写作还需要引用和参考文献。
在学术界，我们需要引用其他学者的观点和研究成果来支持我们自己的论点。
引用的目的是展示我们对相关文献的了解，并避免抄袭。
我们应该正确地引用文献，并在文章末尾列出参考文献列表，以便读者查阅。
在学术写作中，我们还需要注意语法和标点符号的正确使用。
语法错误和标点符号的错误可能会导致句子不清晰或含义模糊。
因此，我们应该仔细检查文章中的语法和标点符号，并确保它们符合英语写作的规范。
最后，学术写作需要经过反复修改和润色。
写作是一个逐步改进的过程，我们应该不断修改和完善我们的文章。
我们可以请同行或老师进行审阅，并根据他们的反馈意见进行修改。
通过反复修改，我们可以提高文章的质量和可读性。
总之，学术综合英语Unit 2介绍了学术写作的基本原则和技巧。
学术写作需要准确、清晰和有条理，遵循特定的结构和组织，正确使用引用和参考文献，并经过反复修改和润色。
通过学习和实践，我们可以提高自己的学术写作能力。

UNIT 2 Economist1.Every field of study has its own language and its own way of thinking. Mathematicians talk about axioms, integrals, and vector spaces. Psychologists talk about ego, id, and cognitive dissonance. Lawyers talk about venue, torts, and promissory estoppel.每个研究领域都有它自己的语言和思考方式。
数学家谈论定理、积分以及向量空间。
心理学家谈论自我、本能、以及认知的不一致性。
律师谈论犯罪地点、侵权行为以及约定的禁止翻供。
2.Economics is no different. Supply, demand, elasticity, comparative advantage, consumer surplus, deadweight loss—these terms are part of the economist’s language. In the coming chapters, you will encounter many new terms and some familiar words that economists use in specialized ways. At first, this new language may seem needlessly arcane. But, as you will see, its value lies in its ability to provide you a new and useful way of thinking about the world in which you live.经济学家也一样。
