The book too much. He 150 yuan it.
A. spent; spent; on
B. cost; spent; on
C. paid; paid; for
D. paid; cost; in

A. spent; spent; on(答案→)B. cost; spent; onC. paid; paid; forD. paid; cost; in解析：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；pay的基本用法是：(1) pay (sb.) money for sth. 付钱（给某人）买……。 (2)pay for sth. 付……的钱。 (3)pay for sb. 替某人付钱。(4)pay sb. 付钱给某人。句意：这本书花钱太多了。他在它上面花了150元。结合语境可知前文主语为物，故用cost，下文主语是人，表示花费，用spend。故选B。

就是这个解释
