问题补充：
to ride a bike from your school to the park?
A. How long did you spend
B. How far did it take
C. How long did it take you
D. How far did you spend
答案：
A. How long did you spend
B. How far did it take
(答案→)C. How long did it take you
D. How far did you spend
解析：how long多长，一般用来表示时间的长短，how far多远，一般用来表示距离的远近。take 用于 it takes sb ... to do sth句型，仅指花费时间（three hours等），必须用it作形式主语，指代下文不定式内容；spend用于sb spend...on sth或者sb spend...in doing sth（in可以省略），spend的主语必须是人，可以指花费时间、也可以指花费金钱；句意：骑车从学校到公园会花费你多长时间？结合语境可知本句中主语是抽象事物，故选C。
