说一下这里应用的语法好了...
答
因为此句中的The doctor and writer 指的是一个人，他既是医生又是作家，所以动词用单数has
答
一个解释是 doctor 和 writer 是指同一个人。
比如
John Brown will be appearing as a guest in tomorrow's program. The doctor and writer has been living here for two years.
答
and连接两个名词时,共用同一个冠词或定冠词时,指一个人或物,谓语动词用单数

The doctor and writer指的同一个人,这个人是医生兼作家
