撰写第一封套磁信时，应注意以下几个要点：

标题

标题应简明扼要，能够吸引教授的注意。例如，如果是申请交通专业，可以直接写“Application for Transportation Program”。避免使用“Hi, How are you”等过于普通的标题。

称呼

使用适当的称呼，如“Dear Prof. XXX”或“Dear Dr. XXXX”，并确保称呼准确无误。

自我介绍

简要介绍自己的基本信息，包括学校、专业、GPA、GT成绩等。

表达兴趣

明确表达对该教授研究领域的兴趣，并说明为什么选择该教授的研究方向。

研究计划和目标

简述自己的研究计划或目标，以及希望加入该教授研究组的愿望。

附件

第一封邮件最好不要带附件，以免给教授留下不专业的印象。

结尾

在邮件结尾处礼貌地表达自己的期待，并留下联系方式，方便教授回复。

个性化

尽量避免使用模板邮件，尽量个性化，让教授感受到你的诚意和独特性。
