是可数名词。
单数例句：My father is a teacher.我的父亲是一名老师
复数例句：Lili's and Marry's fathers are teachers.丽丽的父亲和玛丽的父亲都是老师。
父亲是可数名词
当然是啊，每个人只有一个生父可是father这个英文单词却是可数名词啊，比如说“医院里面有很多等待孩子降生的父亲们”，这里就应该是用复数啊！There are many fathers who are waiting for their babies birth. 看懂这个例句了吗
不知父亲母亲是可数名词，男朋友女朋友还可以有复数呢，比如She is a charming girl who has many boyfriends.
