使用了现在完成时，表达从过去持续到现在的愿望。
Dear Leaders,
Hello! My name is xx, a student majoring in Medical Imaging at xx College of Medicine, class of 20xx.
I was born into a rural family in xx County, xx City, xx Province. Due to old age and the burden of raising several children, my parents' health has declined significantly after years of hard labor, and they currently rely solely on farming to make a living. Since my sister and I are both in college, the financial burden on my family has become quite heavy. My brother works as a temporary police officer, but his meager salary only covers his basic expenses, sometimes requiring financial assistance from my parents. Although my parents never complain about our hardships, we are well aware of their struggles. My father, who once worked heavy manual jobs in his youth, now finds it difficult to sustain such labor due to his aging and declining health. Even farming has become a challenge for him. Consequently, I am driven by a strong desire to help my family and alleviate my parents' burdens.
In September 20xx, I was admitted to the Medical Imaging program at xx College of Medicine. I have always envisioned a future where I can become a dedicated medical professional, alleviating the suffering of patients and contributing to society. Since entering university, I have been working tirelessly toward this goal. While enjoying campus life, I have focused on building a solid foundation of professional knowledge and clinical skills. I understand that being a qualified medical professional requires not only theoretical expertise but also strong moral character and comprehensive skills. I actively participate in various university activities, striving for well-rounded development in morality, intelligence, physical health, aesthetics, and labor. I will continue to pursue excellence and strive for a higher purpose.
尊敬的各级领导：
您好！我是xx医学院xx级医学影像学专业的xx学生。
我出生于xx省xx市xx县的一个农村家庭。由于父母年迈且子女较多，长年的辛勤耕作使他们的身体日益衰弱，目前仅靠务农维持生计。目前，我和姐姐都在读大学，这给家庭带来了沉重的经济负担。我的哥哥是一名临时民警，工资微薄，仅够维持基本生活，在困难时期还需向家里寻求帮助。尽管父母从未在言语中抱怨生活的艰辛，但我们深知家庭的不易。父亲年轻时能干体力活，但随着年龄增长，身体状况大不如前，即便务农也显得力不从心。因此，我渴望通过自己的努力，尽量减轻父母的负担。
20xx年9月，我成功考入了xx医学院影像专业。我曾为自己描绘过未来的蓝图：成为一名优秀的医务工作者，为减轻病患痛苦、贡献社会力量而奋斗。进入大学后，我始终朝着这个目标努力。在学习专业知识的同时，我也注重培养自身的综合素质与思想品德，积极参加学校组织的各类活动，致力于实现德智体美劳的全面发展。我深知，要成为一名合格的“白衣天使”，必须具备深厚的专业理论基础和出色的临床实践能力。我将继续砥砺前行，不断追求卓越。
