国小四年级演讲稿

大家好!

在这个阳光明媚的下午，我走上了讲台，竞选班长这个光荣的职位! 这是我第一次竞选班长，我可能没有老班长遇事时那么沉着冷静;没有那些自信心强的同学处事落落大方，但这是班级给我的一次锻炼机会，我非常地珍惜。我相信，世上无难事，只怕有心人，只要我用心去做，一定会带领我们四、一班干出成绩。

我竞选班长的`优势是热情开朗、热爱集体、团结同学、拥有爱心和责任心。我认为，班长这一职位需要一个有能力有爱心的人来担当，我相信我有这个能力。 假如我当上了班长，我一定会严格要求自己，为同学树立榜样;还会想同学之所想，急同学之所急，时刻准备为同学们服务。相信在我们的共同努力下，充分发挥每个人的聪明才智，我们的班级一定会成为一个团结向上、积极进取的集体。 假如我当上了班长，我会把班级活动作为展示我们特长、爱好的场所，使同学们把学习当作一种乐趣，在集体里互帮互助。 假如我当上了班长，我会每周推荐几本好书，帮助大家买好书，读好书。

当然竞选班长也非易事，因此失败了也没关系，只要我努力奋斗过，我就是最棒的!再说了，“是金子总会发光”，只要我不放弃，努力拼搏，一定会让自己竞选成功。

请大家支持我，相信我!投我一票吧! 谢谢!

General Introduction

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 ClaPrize every semester,In 1999, I got the privilege to enter the graduate program waived of the admission test.

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. 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. 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 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。
