1.介绍. Introduction
Glaucoma is a leading cause of irreversible blindness and an important public health concern. Better understanding of its pathophysiology is important because it might lead to earlier detection and im- proved management strategies. Glaucoma and intraocular pressure (IOP) are tightly correlated genetically and epidemiologically ，but our understanding of cell and tissuelevel processes underlying elevated IOP and glaucoma are not well understood.
The mean IOP was calculated from four readings (two from each eye). Subjects who were receiving IOP-lowering medications or had IOPal- tering surgery were excluded from the analyses.

The IOP measurements were taken using a non-contact air-puff tonometer (Ocular Response
Analyzer, ORA, Reichert, Buffalo, NY).
摘要
Elevated intraocular pressure (IOP) is an important risk factor for glaucoma. Mechanisms involved in its homeostasis are not well understood, but associations between metabolic factors and IOP have been reported. To investigate the relationship between levels of circulating metabolites and IOP, we performed a metabolome-wide association using a machine learning algorithm, and then employing Mendelian Randomization models to fur- ther explore the strength and directionality of effect of the metabolites on IOP.

2.2代谢物测量Metabolite measurements
The eyes share cellular metabolic pathways and physiological mechanisms with other organs and tissues. Genes associated with IOP and POAG are involved, among others, in systemic lipid metabolism ，lysosomal endocytosis and angiogenesis . Additionally, both IOP and POAG are strongly associated with the components of the metabolic syndrome (hyperglycemia, hyperlipidemia and high systemic blood pressure).
2.1
人 口 和 科 目
This is a volunteer cohort recruited from the general population in the United Kingdom . Included in this study are 1763 adults (684 twin pairs and 395 singletons), for whom both metabolite levels (代谢水平)and eye measurements including IOP were available.
青光眼是不可逆转失明 的主要原因，也是重要 的公共卫生问题。 更 好地了解其病理生理学 非常重要，因为它可能 会导致更早发现和改进 管 理策略。 青光眼和 眼压（IOP）在遗传学 和流行病学上密切相关 但 是，我们对眼压和 眼压升高的细胞和组织 水平过程的理解尚不清 楚。
1.介绍. Introduction
Non-targeted metabolite detection and quantification was con- ducted using the platform provided by Metabolon Inc. (Durham, USA) on fasting plasma samples as previously described . Quality control steps for the 529 measured metabolites are reported elsewhere , and they included batch-effect data normalization, outlier (> 4 SD) removal and subsequently inverse-normalization . Only 313 me- tabolites that were measured in at least 90% of subjects were included in analyses.
2.3统计分析. Statistical analyses
2.3.1 随即森林分析代谢物对IOP的影响
Here, we employed a Random Forest (随机森林) machine learning technique (RF) (机器学习技术) which agnosti- cally identifies the metabolites that are most influential over an outcome, regardless of the specific model through which the effect is mediated. These models implicitly capture higher order interactions between variables （变量）. We used RF to rank all available metabolites according to the Breiman-Cutler “VIMP” values . Importance ranking has no associated probabilities, or formal thresholds of sig- nificance, nor any need for multiple-testing correction as long as all variables are tested jointly at the same time. To control for bias from predictor variables’ (metabolites) differing variances , all variables were standard inverse-normalized as previously described .
升高的眼压（IOP）是 青光眼的重要危险因素。 涉及其体内平衡的机制 尚不清楚，但已报道了 代谢因子和IOP之间的 关联。 为了研究循环代 谢物水平与IOP之间的 关系，我们使用机器学 习算法进行代谢组范围 的关联，然后使用孟德 尔随机化模型进一步探 索代谢物在IOP上的强 度和方向性。
摘要
We show that Omethylascorbate, a circulating Vitamin C metabolite, has a significant IOP-lowering effect, consistent with previous knowledge of the anti-hypertensive and antioxidative role of ascorbate compounds. These results enhance understanding of IOP control and may potentially benefit future IOP treatment and reduce vision loss from glaucoma.

It is with great enthusiasm that I share with you my thoughts and experiences, hoping to inspire and motivate you as you embark on your own unique paths.First and foremost, let me express my deepest gratitude to my professors, mentors, and colleagues who have supported and guided me throughout my academic journey. Your knowledge, wisdom, and encouragement have been invaluable. You have taught me not only the intricacies of the English language but also the importance of critical thinking, empathy, and resilience.As English majors, we have had the privilege of exploring the vast and diverse world of literature, from the timeless classics to the contemporary masterpieces. We have delved into the lives of characters who have faced adversity, overcome challenges, and achieved greatness. Through their stories, we have learned valuable lessons about life, love, and the human condition.One of the most significant lessons I have learned is the power of language. The English language is a powerful tool that can inspire, educate, and unite people from all walks of life. It has the ability to bridge cultural gaps, foster understanding, and promote social change.As English majors, we have been equipped with the skills to wield this power effectively.As we approach the end of our academic careers, it is natural to feel a mix of fear and anticipation. Fear of the unknown, fear of failure, and the anticipation of a new chapter in our lives. But let me remind youthat fear is a natural emotion, and it is how we choose to respond to it that defines our character.In the words of George Bernard Shaw, "The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man." Embrace your uniqueness, your quirks, and your passions. Do not beafraid to challenge the status quo and to pursue your dreams with unwavering determination.As we step into the professional world, we must remember that the skills we have acquired go beyond grammar and literature. We have developed strong communication skills, critical thinking abilities, and a global perspective. These are qualities that are highly sought after in today's interconnected world.Here are a few pieces of advice that I would like to share with you as you prepare to venture into the unknown:1. Stay curious. The world is a vast and fascinating place, and there is always something new to learn. Keep your mind open to new ideas, cultures, and experiences.2. Network. Building a strong professional network is crucial for your success. Attend conferences, join professional organizations, andconnect with like-minded individuals. Remember, it's not what you know but who you know.3. Be adaptable. The job market is constantly evolving, and being adaptable will help you stay relevant. Be willing to learn new skillsand embrace change.4. Persevere. Success is not a straight path; it is filled withobstacles and setbacks. Learn from your failures, be resilient, andnever give up on your dreams.5. Stay true to yourself. In the pursuit of success, it is easy to lose sight of who you are and what you stand for. Remember your values, stay true to your beliefs, and let your passion guide you.As we leave the confines of academia, we must remember that our journey does not end here. Life is a continuous learning experience, and every step we take brings us closer to our goals. The world awaits our contributions, and we have the power to make a difference.In conclusion, I want to encourage each and every one of you to embrace your unique talents and pursue your dreams with passion and perseverance.The world is full of opportunities, and it is up to us to seize them. As you embark on this new chapter of your lives, I leave you with a quote from Maya Angelou: "You may encounter many defeats, but you must not be defeated. In fact, it may be necessary to encounter the defeats, so you can know who you are, what you can rise from, how you can still come out of it."Congratulations, Class of [Year]. Go forth and make your mark on the world!Thank you.。

Good morning! It is my great honor to stand here today and share with you my thoughts and experiences as an English major teacher. As we all know, the role of a teacher is of great importance in our society. They are the architects of the future, the ones who shape the minds of the young generation. Therefore, I believe that it is essential for us to recognize and appreciate the efforts of those who dedicate their lives to educating us.First and foremost, I would like to express my heartfelt gratitude toall the English teachers who have influenced my life. Without their guidance and inspiration, I would not have been able to develop a passion for the English language and become the teacher I am today. They have been my role models, and I hope to emulate their dedication, commitment, and passion in my own teaching career.As an English major teacher, my primary responsibility is to nurture and cultivate the language skills of my students. English is not only a means of communication but also a gateway to a world of opportunities. Therefore, it is crucial for us to instill in our students a love for the language and a desire to learn.One of the key qualities that I believe a great English teacher should possess is patience.

I often remind myself that every student is unique and has their own pace of learning. By showing patience and understanding, we can help our students overcome their challenges and achieve their full potential.Another essential quality is the ability to create an engaging and interactive learning environment. A teacher who is passionate abouttheir subject can easily ignite the curiosity and enthusiasm of their students. I strive to incorporate various teaching methods, such as group discussions, role-playing, and project-based learning, to make the learning process more dynamic and enjoyable. By doing so, I hope to motivate my students to actively participate in the classroom and develop their critical thinking and problem-solving skills.In addition to teaching language skills, it is also my responsibility to impart cultural knowledge to my students. English is a global language, and it is essential for us to understand the diverse cultures and traditions that it represents. I make it a point to integrate cultural elements into my lessons, such as famous literary works, films, and songs, to provide my students with a broader perspective of the world. Through this, I hope to foster cultural awareness and empathy among my students.Furthermore, a great English teacher should be a lifelong learner themselves. The field of English education is constantly evolving, andit is our duty to keep up with the latest trends and techniques. I regularly attend workshops, seminars, and conferences to enhance my teaching skills and stay updated with the latest research in the field.I believe that a teacher who is willing to learn and grow can inspire their students to do the same.One of the most rewarding aspects of being an English teacher is witnessing the growth and development of my students. There have been countless moments when I have seen my students transform from hesitant beginners to confident speakers and writers. These moments are truly heartwarming and remind me of the impact we can have on the lives of our students.However, being a teacher also comes with its challenges. We often face criticism and pressure to produce academic results. It is important for us to stay resilient and maintain our dedication to our students. We must remember that our ultimate goal is to help our students becomewell-rounded individuals who can contribute positively to society.In conclusion, being an English major teacher is a noble profession that requires dedication, commitment, and passion. We have the power to shape the future of our students and inspire them to achieve their dreams.

英语专业话题演讲跨文化交流逐字稿
跨文化交流的重要性Cross-cultural communication is the process of communication between people who interpret the information in different way because of their different cultural context.Culture and communication are closely related. The interaction of culture and communication is so pervasive that separating the two is virtually impossible. The way you communicate is deeply influenced by the culture in which you were raised. To a large degree, your culture influences the way you think, members of your society decode their message according to the assumptions of their culture. The greater the difference between cultures, the greater the chance for misunderstanding.With the development of globalization and the deepening of reform and opening up, the communication between China and other countries becomes deeper and wider. Therefore, it is becoming increasingly important for Chinese student to improve their English competence and promote their cross-cultural communication ability to achieve effective communicationHowever, in cross-cultural communication, breakdown often occur between speaker and hearer from different cultural background.The technical term for it is pragmatic failure. It occurs when the speaker fails to use language effectively to achieve specific communicative purposes or when the hearer fails to recognize the intention or the illocutionary force of the speaker’s utterance in the context of communication.There are some barriers which hinder us from communicating effectively. Therefore, it is critical to understand the barriers in cross-cultural communication and to know the techniques and strategies that can be employed to break down these barriers between two cross-cultural parties.There are 4 barriers for cross-cultural communications1.EthnocentrismEthnocentrism refers to the perception that one’s own culture is superiorto other cultures. It is natural to take pride of your own country and culture.However, this does not mean that you can claim superiority of your own culture over others. According to brown, all human being build sets of defense to protect the ego in their understanding of themselves. But the defense which we place between ourselves and others will create barrier in cross-cultural communication.2.StereotypingCultural stereotype refers to the oversimplified picture we form of other cultures in the bias of our own culture-bound world view. For example, American, British. it has negative effect, to judge.nguage barriersDifferent People may have level of language competence. The divergence of language competence is also likely to impede effective comprehension and communication. Besides, people from different part of the world use a variety of pronunciation and accents, which impede smooth communication and comprehension of others.4.Conflicting valuesEveryone has their own set of beliefs, attitudes and values. Failure to understand the differing beliefs and values will prevent effective cross-cultural communication.How to overcome theses barriers in cross-cultural communication?Improving the Cross-Cultural CompetenceCross-cultural competence is described as the ability understand people from different cultures and engage with them effectively. The cross- cultural competence could be improved through the following methods:1.Cross-cultural knowledge learningWe need to understand and accept the fact that there is a gap between different culture.we need to concede that there is differences between societies and that these differences include values, beliefs and convictions. Therefore, we need some fundamental intercultural knowledge learning which allows us to be aware andmindful of the differences in cultures.nguage TrainingLanguage barriers are often the most common issues experienced in multicultural groups. Therefore, providing language training should be given for individuals so that there is more of a chance of effectively communicating in a cross-cultural environment.3.Keep your personal beliefs personalEach person has his/ her own religious or other beliefs. Consequently, it is vital to respect and not judge one another’s beliefs and not impose one’s own values, attitudes and beliefs.4.Building trust across cross cultureIf people from different culture backgrounds can build and earn trust among each other and appreciate the differences, a healthy relationship may be formed which will play a critical role in developing effective cross-cultural communication.。

英语专业口语课演讲稿范文
Ladies and gentlemen,Good morning/afternoon! It is my great honor to stand before you today to deliver a speech on the topic of "The Power of Language: Exploring the World Through English." As English majors, we are all well aware of the significance of language in our lives. Language is not just a tool for communication; it is a bridge that connects different cultures, a key that unlocks the doors to countless opportunities, and a mirror that reflects our own identity.Firstly, let us delve into the role of language as a bridge between cultures. As English is the lingua franca of today's world, it has become a universal language that connects people from diverse backgrounds. Through English, we can share our thoughts, ideas, and experiences with individuals from all corners of the globe. This has led to a more interconnected and understanding world, where cultural differences are celebrated rather than feared.Consider the following scenario: A Chinese student, Li Wei, travels to the United States to study at a renowned university. Initially, he struggles to adapt to the new environment and communicate with his professors and classmates. However, with time and perseverance, Li Wei learns to speak English fluently. Now, he is not only able to excel academically but also to make friends from various countries. Through English, Li Wei has not only broadened his horizons but also gained a deeper appreciation for different cultures.Moreover, English is a key that unlocks countless opportunities. In today's globalized world, proficiency in English is a prerequisite for success in various fields, such as business, technology, and education. Companies around the world are increasingly looking for employees who can communicate effectively in English, as it facilitates international trade and collaboration. Similarly, English proficiency is crucial for those who aspire to work in multinational organizations or embark on international assignments.Take, for instance, the career of Zhang Hua, a young Chinese entrepreneur. After completing her studies in marketing, Zhang Huadecides to start her own business. However, she soon realizes that her English skills are a major barrier to her success. To overcome this challenge, she enrolls in an English language course and workstirelessly to improve her proficiency. As a result, Zhang Hua is now able to successfully market her products to international customers and expand her business globally.Furthermore, language is a mirror that reflects our own identity. As English majors, we have chosen to study this beautiful language, which has its roots in the rich history and culture of the British Isles. By learning English, we not only acquire a new set of skills but also gain insight into our own cultural heritage. We learn to appreciate the nuances of language and the importance of communication in our daily lives.Consider the following example: Wang Li is a native Chinese speaker who has been studying English for several years. As she becomes more proficient in the language, she begins to notice similarities between Chinese and English, such as the use of proverbs and idioms. This realization not only deepens her understanding of her own language but also enhances her appreciation for English literature and poetry.In conclusion, the power of language, particularly English, is undeniable. It serves as a bridge between cultures, a key to opportunities, and a mirror to our own identity. As English majors, we have the privilege of studying this magnificent language and utilizingit to our advantage. Let us embrace this opportunity and strive to become proficient speakers, writers, and thinkers in English. By doing so, we will not only contribute to the global community but also enrich our own lives.In closing, I would like to leave you with the following quote by George Bernard Shaw: "The single biggest problem in communication is theillusion that it has taken place." Let us all strive to ensure that our communication, whether in English or any other language, is effective and meaningful. Thank you for your attention, and I welcome any questions or comments you may have.Thank you.。
