pay后与for连用，表示钱的支付，钱和时间的花费均可用spend, 用法为; spend sb some time (in) doing sth speng sb some money (in) doing sth，物作主语用cost;花时间做某事多用take，用法为take sb some time to do sth

pay 人做主语 例如，I pay 5 yuan for the book.
spend 固定搭配 sb. spend 钱/时间 on sth. 或者 sb. spend 钱/时间 （in）doing sth. 其中in可省略。例如 I spend 50 yuan on the coat.=I spend 50 yuan (in) buying the coat.
cost 物做主语 例如 The coat costs me 50 yuan.
