你认识这样的人吗？已经读到博士或拥有多个学位却依然寻求深造机会，而同龄人都已经工作好多年了。读书似乎是他们最大的乐趣和人生的意义所在。这样的人被称为“专业学生”，英文表达是professional student。
Professional student refers to a person who receives multiple degrees and keeps taking courses instead of holding a profession related to the degrees earned. It can be a compliment or an insult depending on the speaker.
“专业学生”指的是那种已经拿到好几个学位，依然继续进修深造，而不是去从事和既得学位有关的职业的人。这个称号可能是褒扬，也可能是挖苦，取决于讲话的人。
