Question

The station is about five kilometers______ his home. A far Baway Cfrom Dfar from

Answer 1

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！

Answer 2

选D，far from somewhere表示距离某地多远，far一般不单独出现，若变为问句则为How far is it from your home to the station?
