The professor and writer is invited to many universities to deliver lectures.为什么要用is而不用are?

问题描述:

The professor and writer is invited to many universities to deliver lectures.
为什么要用is而不用are?

这里的the professor and teacher是同一个人,他既是教授,又是作家,当一个人身兼数职时,常用一个冠词加and来连接,这是一种固定用法

这是同一个人,既是个教授,同时也是作家
如果是两个人 应该是 the professor and the writer

主语只有一个人哦,不过这个人有两个身份——教授和作家.
