例如：Itusuallytakesmehalfanhourtodomyhomework.

做作业通常花费我半小时的时间。Studentsoftenspendoneandahalfhours(in)doinghomework.

学生们经常花一个半小时的时间做作业。Ipaid10yuanforthisbook.

我买这本书付了十元钱。根据以上例句可知：

Ittakessb.sometimetodosth.意为“花费某人……时间来做某事”。

spend

的主语必须是人，而spend…onsth.意为“买某物花了……钱”。spend+时间+(in)doing意为“花费多少时间来做某事”。可以与ittakessb.sometimetodosth.来进行句型转换。

pay

的主语必须是人，而“花钱买某物”为pay…for。
