你是在什么场合用?求职还是开学典礼之类的?
自己看哪个合适吧
1.Hello everyone, my name is Lee. This is really a great honor to have this opportunity, and I believe I can make good performance today. Now I will introduce myself briefly. I am 20 years old,born in Guangdong province, south of China, and I am a senior student at Guangdong **University. My major is English. And I will receive my bachelor degree after my graduation in June. In the past four years, I spent most of my time on study. I passed CET4 and CET6 with a ease and acquired basic theoretical and practical knowledge of Language. Besides, I have attended several Speech competition held in Beijing, which really showed our professional advantages. I have taken a tour to some big factories and companies, through which I got a deep understanding of English for application. Compared to developed countries, unfortunately, although we have made extraordinary progress since 1998, our packaging industry is still underdeveloped, messy and unstable, and the situation of employees in the field is awkward. But I have full confidence in its bright future if only our economy can be kept at the growth pace still. I guess you may be interested in why I choose this job. I would like to tell you that this job is one of my lifelong goals. If I can work here,I will work hard. As to my character, I cannot describe it well, but I know I am optimistic and confident. Sometimes I prefer to stay alone, reading and listening to the music, but I am not lonely, for I like to chat with my classmates about almost everything. My favorite pastime is to play volleyball, to play cards or to surf online. From life at university, I learn how to balance study and entertainment. By the way, I was an actor in our amazing drama club. I have a few glorious memories on stage. That is my pride...（）有些句子可以按需要前后换位.

I am a third year master major in automation at Shanghai Jiao Tong University, P. R. China. With tremendous interest in Industrial Engineering, I am writing to apply for acceptance into your Ph.D. graduate program.
Education background
In 1995, I entered the Nanjing University of Science & Technology (NUST) -- widely considered one of the China’s best engineering schools. During the following undergraduate study, my academic records kept distinguished among the whole department. I was granted First Class Prize every semester, and my overall GPA(89.5/100) ranked No.1 among 113 students. In 1999, I got the privilege to enter the graduate program waived of the admission test. I selected the Shanghai Jiao Tong University to continue my study for its best reputation on Combinatorial Optimization and Network Scheduling where my research interest lies.
At the period of my graduate study, my overall GPA(3.77/4.0) ranked top 5% in the department. In the second semester, I became teacher assistant that is given to talented and matured students only. This year, I won the Acer Scholarship as the one and only candidate in my department, which is the ultimate accolade for distinguished students endowed by my university. Presently, I am preparing my graduation thesis and trying for the honor of Excellent Graduation Thesis.
Research experience and academic activity
When a sophomore, I joined the Association of AI Enthusiast and began to narrow down my interest for my future research. In 1997, I participated in simulation tool development for the scheduling system in Prof. Wang’s lab. With the tool of OpenGL and Matlab, I designed a simulation program for transportation scheduling system. It is now widely used by different research groups in NUST. In 1998, I assumed and fulfilled a sewage analysis & dispose project for Nanjing sewage treatment plant. This was my first practice to convert a laboratory idea to a commercial product.
In 1999, I joined the distinguished Professor Yu-Geng Xis research group aiming at Network flow problem solving and Heuristic algorithm research. Soon I was engaged in the FuDan Gene Database Design. My duty was to pick up the useful information among different kinds of gene matching format. Through the comparison and analysis for many heuristic algorithms, I introduced an improved evolutionary algorithm -- Multi-population Genetic Algorithm. By dividing a whole population into several sub-populations, this improved algorithm can effectively prevent GA from local convergence and promote various evolutionary orientations. It proved more efficiently than SGA in experiments, too. In the second semester, I joined the workshop-scheduling research in Shanghai Heavy Duty Tyre plant. The scheduling was designed for the rubber-making process that covered not only discrete but also continuous circumstances. To make a balance point between optimization quality and time cost, I proposed a Dynamic Layered Scheduling method based on hybrid Petri Nets. The practical application showed that the average makespan was shortened by a large scale. I also publicized two papers in core journals with this idea. Recently, I am doing research in the Composite Predict of the Electrical Power system assisted with the technology of Data Mining for Bao Steel. I try to combine the Decision Tree with Receding Optimization to provide a new solution for the Composite Predictive Problem. This project is now under construction.
Besides, In July 2000, I got the opportunity to give a lecture in English in Asia Control Conference (ASCC) which is one of the top-level conferences among the world in the area of control and automation. In my senior year, I met Prof. Xiao-Song Lin, a visiting professor of mathematics from University of California-Riverside, I learned graph theory from him for my network research. These experiences all rapidly expanded my knowledge of English and the understanding of western culture.
I hope to study in depth
In retrospect, I find myself standing on a solid basis in both theory and experience, which has prepared me for the Ph.D. program. My future research interests include: Network Scheduling Problem, Heuristic Algorithm research (especially in GA and Neural network), Supply chain network research, Hybrid system performance analysis with Petri nets and Data Mining.
Please give my application materials a serious consideration. Thank you very much
