The station is about five kilometers______ his home.A far Ba

选 C
距离 + from 或者 away from +地点 表示离某地有多远的距离
far 本身就是个模糊的距离概念,绝对不能和具体的距离同时使用.
想一下：
My home is far from my school.= My home is far away from my school.
My home is 2 kilometers from my school.= My home is 2 kilometers away from my school.
其实上面两组句子的意义是一样的,只不过第二组具体些吧.
供参考,祝进步!
