问题补充：
It us over ten hours to get to the small village the bus.
A. spent; by
B. cost; in
C. took; by
D. took; on
答案：
A. spent; by
B. cost; in
C. took; by
(答案→)D. took; on
解析：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；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；cost用于 sth costs sb sth，主语必须是物，多指花费金钱，少数情况可指花费时间、气力，有时表示成本的消耗；在表达交通方式时，by后面直接加交通工具。On +the +交通工具。本题主语it为物，故选D。
