根据报考的专业特点，强调自己的个性和优势。例如，如果报考的是学术性专业，可以说自己细心、条理分明、踏实等；如果是研究性、应用性更强的专业，可以说自己负责、可靠、有效率等。例如：
I believe my meticulous nature and logical thinking skills will contribute significantly to your department. I am also a steady and reliable student who values efficiency in research.
结束语
简洁明了地结束开场白，为后续的面试内容做好铺垫。例如：
