• Please submit a graded paper from your junior or senior year that best represents your writing skills and analytical abilities. We are particularly interested in your ability to construct a tightly reasoned, persuasive argument that calls upon literary, sociological or historical evidence. You should NOT submit a laboratory report, journal entry, creative writing sample or in-class essay.
• If you have engaged in significant research in the natural sciences, mathematics, computer science, social sciences or humanities that was undertaken independently of your high school curriculum, please provide a brief description of the research project.

解析：此类题目并不是要求学生专门新写一篇留学文书，而是让学生提交已有的论文以考察他们在平时学习环境中的学术英文水平和逻辑分析能力。有些题目中会特意要求要带有教师的批改和评分，这样从侧面可以考察申请者所就读中学的学术严谨程度。对于希望申请理科的学生，如果符合题意的话可以考虑提交研究性学习的报告翻译，并让指导老师另行批改一下。
