self-introduction Good morning/afternoon, esteemed professors and lecturers.It’s an honor to be standing up here today. Thank you for giving me this chance. First let me introduce myself. My name is Yuan Yuan, I will finish my undergraduate education in Huangshan University,and my major is Biotechnology .Although I don't know much about my university, I still appreciate it, because it gives me a chance to develop my ability. The school I applied for is Donghua University, and I would like to have the chance to complete my long-awaited study here. My interest in biology began in junior high school, when I began to have a different understanding of the world. The study of biology in high school also encouraged me to engage in the research of biology in the future. In college, I majored in biotechnology.During my four-years study in the university , I have laid the foundation of professional knowledge, and acquired rich experimental experiences. I passed the examination of cet-4. In order to apply the learning theory to scientific research, I studied in the plankton laboratory of my school from April, 2017 to June, 2017. The study in the laboratory enabled me to master the basic experimental operation of alga separation, cultivation and preservation, and to understand the daily management of alga culture and the observation and inspection of its growth. Under the guidance of my tutor and the discussion and exchange with my senior brothers and sisters, I have gained a lot of experimental experience.All these experiences made me become more and more interested in Biology. With the further understanding of professional knowledge, I gradually realized that my knowledge and ability were far from enough, so I chose to continue my study. The choice of biochemistry and molecular biology is a continuation of my undergraduate study and also a persistence of my interest. All in all, Donghua University, with a highly qualified faculty and strong academic environment is the university I have long admired. if I am given a chance to further my education in this famous University, I will spare no effort to master the latest knowledge in my field and make good preparation for my future study. If possible， I will go on with my study for doctorate degree. Thank you very much for your time and attention。
