苹果CEO库克在华盛顿大学2015年毕业典礼演讲 中英双语
苹果CEO库克在华盛顿大学2015年毕业典礼演(2015-05-20)5月18日,苹果首席执行官蒂姆·库克(Tim Cook)参加了美国乔治华盛顿大学毕业典礼,并发表了题为《总会有人改变世界的——这个人可能就是你》(someone has to change the world —it might as well be you)的主题演讲。
与十年前乔布斯的“求知若饥,虚心若愚”遥相呼应,库克这次面对乔治华盛顿大学即将走向社会的毕业生讲出的“金句”也是频频发人深省。
公平是一种权利!毕业生要与不公平抗争库克发表演讲的地方是在华盛顿国家广场,那里距离华盛顿纪念碑不远。
华盛顿大学宣称,当时有2.5万人参加此次毕业典礼,包括6000名毕业生。
库克称:“正是在这里,金挑战所有美国人,让民主的观念深入人心。
正是在这里,里根总统号召我们相信自己,相信我们能够做出伟业。
大学毕业生应该坚守自己的信念,他还说自己一路奋斗走来,让他愈发觉得,公平是一种权利,而作为毕业生要勇于与不公平做抗争。
”·与州长见面不是我的荣誉,握着他的手就像是对我信仰的背叛演讲刚开始,库克就讲述了美国近代史的一些故事。
他说,他心中的英雄是马丁路德金和总统肯尼迪,因为他们将正义和民主带到现实中来。
16 岁时库克因为获得一次论文大赛的奖项,时任阿拉巴马州州长George Wallace 亲自接待了库克以及其他获奖的小伙伴。
而库克为Wallace 的“接见”感到耻辱,因为后者曾推进种族隔离,并禁止黑人上大学。
他说:”与州长见面不是我的荣誉,握着他的手就像是对我信仰的背叛。
”·毕业生们不光要吃饱饭也要坚持梦想你不必在“做正确的事”和“好的生活”中作抉择。
若说乔布斯的那次演讲代表着一往无前的勇气,库克的理念则更接地气,他希望同学们在吃饱肚子的前提下坚持梦想。
·总会有人改变世界,可能就是你他还鼓励学生:“不要害怕挑战,也不要一味愤世嫉俗或批评别人,历史从来都不是由一个人写下的,但也从来不会忘记一个人的贡献,这个写下历史的人可能就是你,那个人应该就是你,那个人必须就是你。

关于树的英语作文开头
Trees are an integral part of our ecosystem,providing a myriad of benefits that contribute to the wellbeing of the environment and humanity.They stand tall,their roots firmly anchored in the earth,while their branches reach out to the sky,symbolizing the connection between the heavens and the earth.In the beginning of any essay about trees, its important to capture the essence of these magnificent beings.To start an essay on trees,one might consider the following opening sentences:1.Since the dawn of time,trees have stood as silent sentinels,guardians of the earth, offering shade,shelter,and sustenance to countless species.2.The first trees emerged on our planet millions of years ago,and since then,they have played a pivotal role in shaping the landscapes and the lives of organisms that inhabit them.3.In the hush of the forest,where the whispers of the wind dance among the leaves,one can find solace and inspiration,for trees are not just living organisms,but also poets of the natural world.4.As I walked beneath the canopy of a towering oak,I was struck by the profound sense of history and continuity that trees represent,their rings telling stories of ages past.5.The tree,with its complex network of roots and branches,is a metaphor for life itself interconnected,resilient,and evergrowing.These openings set the stage for a deeper exploration of the various aspects of trees,from their biological functions and ecological importance to their cultural and emotional significance in human societies.Whether the essay delves into the scientific,the aesthetic, or the philosophical,the opening lines should invite the reader to appreciate the grandeur and the multifaceted roles that trees play in our world.。
被剥夺了国籍的英语作文
As a high school student, Ive always been fascinated by the concept of nationality and the rights and responsibilities it entails. But what happens when someone loses their nationality? This thoughtprovoking question has led me on a journey of exploration into the complexities of citizenship and the profound impact it has on an individuals life.Growing up, I was always proud of my nationality, feeling a sense of belonging and identity that it provided. It was a part of who I was, shaping my worldview and my place in the world. However, a documentary I watched last year about stateless people opened my eyes to a reality that I had never considered before.The documentary featured the story of a man named Ali, who was born in a country that later dissolved due to political upheaval. As borders shifted and governments changed, Ali found himself without a nationality. He couldnt vote, travel, or even access basic services like healthcare and education. His life was filled with uncertainty and a constant struggle for recognition and acceptance.This story resonated with me deeply, making me realize the importance of nationality in providing stability and security. Its not just about having a passport or a flag to identify with its about having a sense of belonging and the legal protections that come with it.I decided to delve deeper into this issue, researching the reasons why people might lose their nationality. I learned that it can happen for various reasons, such as political persecution, war, or even bureaucratic errors. Insome cases, people are born stateless because their parents were stateless or because they were born in a place that doesnt recognize the right to nationality.One striking example I came across was the case of the Rohingya people in Myanmar. Denied citizenship by the government, they face severe discrimination and persecution, leading many to flee their homes in search of safety. Their lack of nationality makes it incredibly difficult for them to find refuge elsewhere, as they are not recognized as citizens of any country.The more I learned about these issues, the more I began to question the fairness of our global system of nationality. Why should someones life chances be determined by the arbitrary lines drawn on a map or the decisions of politicians? It seems fundamentally unjust that a persons rights and opportunities can be so drastically limited by something as seemingly arbitrary as their nationality.This exploration has also made me appreciate my own nationality more. I realize that I have been incredibly fortunate to have a stable and recognized nationality that provides me with a sense of security and belonging. I am grateful for the opportunities it has given me and the freedom it allows me to enjoy.At the same time, I feel a sense of responsibility to use my privilege to raise awareness about the plight of those who have been deprived of their nationality. I believe that it is our collective duty as global citizens to work towards a more just and inclusive world where everyone has the right to anationality and the protections it provides.In conclusion, the experience of researching and reflecting on the issue of nationality deprivation has been both enlightening and humbling. It has made me realize the importance of nationality in shaping our lives and the need for greater empathy and understanding towards those who have lost this fundamental aspect of their identity. As we move forward, lets strive to create a world where everyone can enjoy the rights and protections that come with being a recognized citizen.。

In the realm of crafting an enlightening essay in English, it's essential to embark on a journey that not only captivates the reader but also delves deep into the realms of knowledge and insight. Let us embark on this odyssey together, exploring the nuances of language, thought, and expression.Enlightenment, as a concept, transcends mere understanding; it embodies a profound awakening of the mind and spirit. In our quest to illuminate the path, we navigate through the corridors of history, philosophy, and personal introspection.Firstly, let us gaze upon the tapestry of history, where the seeds of enlightenment were sown in the fertile soil of human consciousness. The Age of Enlightenment, spanning the 17th and 18th centuries, ushered in an era ofintellectual revolution, challenging the dogmas of the past and heralding the dawn of reason. Thinkers like Voltaire, Rousseau, and Locke illuminated the intellectual landscape with their radical ideas, advocating for liberty, equality, and fraternity.Moreover, enlightenment is not confined to the annals of history; it is an ongoing process, an ever-evolving journey of discovery and understanding. In the modern era, technological advancements have catalyzed the spread of knowledge like never before. The internet, with its vast repositories of information, serves as a beacon of enlightenment, empowering individuals to access knowledge at their fingertips.Furthermore, enlightenment transcends the realm of academia, permeating every facet of human existence. It is found in the quiet contemplation of nature's beauty, the pursuit of artistic expression, and the bonds forged through empathy and compassion. Each moment presents an opportunity for enlightenment, a chance to see the world through fresh eyes and cultivate a deeper understanding ofourselves and others.In the realm of literature, enlightenment finds expression through the written word, where authors weave intricate tapestries of meaning and insight. From the timeless wisdom of Shakespeare to the existential ponderings of Camus, literature serves as a mirror reflecting the human condition in all its complexity and diversity.Moreover, the pursuit of enlightenment is not without its challenges and obstacles. It requires courage to question the status quo, humility to admit ignorance, and perseverance to continue the journey in the face of adversity. Yet, it is through these trials that the light of understanding shines brightest, illuminating the path forward with newfound clarity and purpose.In conclusion, the journey of enlightenment is a voyage of discovery, a quest to unravel the mysteries of the universe and uncover the truths that lie hidden beneath the surface. Through the exploration of history, philosophy,literature, and personal introspection, we inch closer to the elusive goal of enlightenment, one step at a time. As we navigate the turbulent waters of existence, let us embrace the journey with open minds and hearts, for it is through enlightenment that we truly come to know ourselves and our place in the universe.。

ABSTRACT
Fifteen years ago lin-4 was reported to be the first endogenous small non-coding, but interfering RNA structure involved in developmental timing in C. elegans. First thought not, or only rarely, to occur in mammals, microRNAs are now among the major players in up-to-date genomic research. The mature molecules are ~22 nucleotides in length and, by targeting predominantly the 3’ UTR of mRNAs, lead to translational repression or degradation of the target message, hence controlling important cellular mechanisms, including division, differentiation and death. This key role makes them excellent targets for cancer research. In fact they have been shown to have a major impact on cancer development in many cases. However, miRNAs are not a homogeneous class and can be subclassified into intragenic and intergenic, depending on their genomic position. Whereas intergenic miRNAs are expected to be independent transcriptional units, intragenic miRNAs are commonly believed to be regulated through their host gene. Despite of the growing knowledge on how miRNAs integrate into cellular regulatory networks, our current knowledge about the specific role of intragenic miRNAs is rather limited. In this work we integrated current miRNA knowledge bases, ranging from miRNA sequence and genomic localization information to target prediction, with biochemical pathway information and publicly available expression data to investigate functional properties of intragenic miRNAs and their relationship to their host genes. To the best of our knowledge, we are the first to show in a large-scale analysis that intragenic miRNAs seem to act as negative feedback regulators on multiple levels. We furthermore investigated the impact of this model on the potential role of intronic miRNAs in cancer pathogenesis.
