有具体数字时，应与away from连用，口语中常省略away。如：How far is it from the school to the TV station? 从学校到电视台有多远？It is about 20 kilometers (away from the school). 没有具体数字时，应用far或near作答。如How far is it from your home to school? = How far is school from your home? It is very near. I walk to school every day. 很近，我每天步行去上学。
