Respected School Leaders and Scholarship Committee Members:
Hello. My name is Li XX, a student in the Nursing Vocational Class (3) 08-11. I come from a remote rural family of six, and our current income is quite limited. The high tuition and living expenses during my university years have placed a heavy burden on my family, which is further strained by my brother's hepatitis treatment. Consequently, I have always practiced strict frugality at school to help ease the financial pressure on my family.
It is said that "children from poor families grow up to be responsible." Life's hardships have not weakened my will; instead, they have driven me to study even more diligently. In the last semester, my academic performance was among the best in my class, which demonstrates my dedication and perseverance.
Now in my sophomore year, I realize that my family's financial situation is unlikely to change in the near future. During my time at school, I have always maintained high personal standards and was honored as an "Excellent Youth League Member." I have a perfect attendance record, consistently attending all classes—whether professional or theoretical—which has allowed me to avoid any remedial exams. I firmly believe that the knowledge we acquire is the only thing that truly belongs to us. Although the weight of our struggles can sometimes feel overwhelming, I know that only through continuous effort can I change my destiny.
尊敬的学校领导、励志奖学金评委组：
您好。我叫李xx，是护理高职（3）08—11班的学生。我来自一个偏远农村家庭，家中共有六口人，目前的经济来源非常有限。大学期间高昂的学费与生活费给家庭带来了沉重的负担，加之弟弟正在接受乙肝治疗，家庭经济压力倍增。因此，在校期间我始终保持勤俭节约的习惯，努力减轻家庭的负担。
俗话说“穷人的孩子早当家”，生活中的重重困难并未消磨我的意志，反而激励我更加刻苦学习。在上学期，我的各科成绩均名列班级前茅，这充分证明了我的勤奋与坚持。
作为一名大二的学生，我深知家庭经济的困难在短期内难以改变。在校期间，我始终严于律己，曾被评为“优秀团员”。在学习上，我从未缺课，无论是专业课还是理论课，我都会认真听讲，因此两年下来从未参加过补考。我深知，唯有学到的知识是真正属于自己的。虽然生活中的艰辛有时令人感到沉重，但我明白，唯有通过不断的努力，才能改变命运。
