他是英语专业的学生吗？用英语怎么说

major:主要的 n.少校；专业(学生) vi.主修

作为名词，major指专业：
Is his major English
将句子还原为肯定句就是 His major is English

作为不及物动词，major后要加in 再加科目：
Does he major in English?
还原为肯定句就是He majors in English.

如果按楼主的说法，major作为名词
你的问法也可以说 1、Is he a student majors in English?
2、Is he a English major student？

肯定不对啊，因为句子中出现了两个动词，正确翻译应该是：Does he major in English?

Is he majoring in English?

或者：Is his major English?

太chinglish了。。。
Dose he major in English?

Does he major in English?
