尊敬的老师：
我叫xxx，是xx大学化学学院20xx级有机化学硕士研究生，通过贵所博士招生信息介绍和师兄的推荐，我希望能够有机会报考您20xx年的博士研究生，所以非常冒昧的给您写信。
硕士期间我主要在做xx工作(简单的介绍下自己硕士期间作的工作)，经过两年多的学习和实践，在导师的精心指导以及实验室良好的学术氛围影响下，我在设计实验、操作能力，以及论文撰写方面积累了一定的经验，为读博打下坚实的基础。
我在网上查阅了您的有关资料，并看了些您发表的文章，对您所研究的课题很感兴趣，所以非常的希望能在您的课题组攻读我的博士学位，我相信通过自己的努力，我能很好的完成博士期间的任务。
冒昧致信，恳请您海涵!非常感谢您能在百忙之中抽出时间阅信!
此致!
祝身体健康! 工作愉快!
