Dear Professor Anderson,
I hope this letter finds you well. I am writing to express my heartfelt gratitude for the profound impact you have had on my academic journey during my time at Stanford University. As I prepare to graduate with a master’s degree in Mechanical Engineering, I reflect on how your guidance, expertise, and unwavering support have shaped both my research and my confidence as a scholar.
From the first day I joined your robotics lab, you welcomed me with patience, even when my limited research experience led to countless questions. Your detailed feedback on my experiments with autonomous vehicles and your willingness to share your own research failures taught me more than just technical skills – they taught me resilience. When I doubted my ability to publish our joint paper in Journal of Mechanical Design, your reassurance and careful revision of my drafts gave me the courage to persevere. The paper’s acceptance last month is a testament to your mentorship.
Beyond the lab, your openness to discussing career paths – from academia to industry – helped me clarify my goals. Your advice to “prioritize curiosity over perfection” has become my mantra, and I will carry this mindset into my future role as a research engineer at XYZ Company.
Thank you for going above and beyond as a mentor, educator, and role model. I hope to make you proud as I continue to learn and contribute to the field. Please stay in touch – I would be honored to update you on my progress.
Warm regards,
Li Hua

Dear Mom and Dad,
As I sit in my dorm room, just weeks away from graduating from UCLA, I can’t believe how fast these four years have flown by. I want to take a moment to say thank you – for everything.
Thank you for sacrificing so much to make my American dream a reality. I know saving for my tuition wasn’t easy, and every time I called home stressed about exams or culture shock, you listened without judgment. Remember when I cried over my first failed midterm? Your words – “Failure is just a step, not the end” – gave me the strength to retake the class and thrive.
Thank you for trusting me to navigate this journey on my own, even when it meant me skyping you at 3 a.m. to share my first internship offer or my fears about living alone. Your belief in me has been my anchor. I’ve grown so much here – learning to cook (badly, but still!), advocating for myself in a new language, and discovering a passion for public health. None of this would have been possible without your love and support.
I can’t wait to come home and hug you both, but even more, I can’t wait to make you proud as I start my job at the CDC next month. I love you more than words, and I’ll spend the rest of my life trying to repay your kindness.
Always grateful,
Anna

To the XYZ Foundation Scholarship Committee,
I am writing to sincerely thank you for awarding me the 2023-2025 XYZ Global Scholarship, which has been instrumental in allowing me to pursue my bachelor’s degree in Environmental Science at Columbia University. Your generosity has not only eased the financial burden of studying abroad but has also empowered me to fully engage in academic and extracurricular opportunities that align with my goal of combating climate change.
With your support, I was able to enroll in courses like “Sustainable Urban Policy” and conduct field research on NYC’s carbon reduction initiatives. I also joined the Student Environmental Justice Alliance, where we lobbied for renewable energy funding in low-income neighborhoods. These experiences deepened my understanding of how policy and community action can drive change, and I am now committed to pursuing a career in international climate policy.
Your investment in students like me is a testament to your belief in the power of education to create a better world. As I graduate and prepare to join the United Nations Environment Programme, I will carry your trust with me, striving to make an impact in the field you have helped me enter.
Thank you again for changing my life. I hope to make the XYZ Foundation proud through my work and continue your mission of fostering global sustainability leaders.
Sincerely,
Zhang Wei
三、写作小贴士
- 具体性 > 笼统：避免 “感谢你的帮助”，而是写 “感谢你在 2024 年 12 月我申请实习时，连夜帮我修改简历并联系业内人士推荐”。
- 情感真挚：无需华丽辞藻，用细节体现真实感受（如：“你办公室的门永远为学生敞开，让我在异国他乡感受到了师长的温暖”）。
- 格式规范：正式信件使用学校 / 个人信头，注明地址和日期；非正式信件可简洁温馨。
- 主动跟进：若写给教授 / 导师，可随信附上简历或近期成果，体现 “你的帮助带来了切实改变”。
根据实际对象调整内容，让对方感受到你铭记于心的感激和具体的成长，这封信就会格外动人。祝书写顺利，也愿你的留学生活圆满收官！ 🎉
