pay offer spend cost 有什么区别?

首先,offer的意思是出价,多指卖主.而spend,pay,cost意思是花费.多指买主.
cost是物品花费人多少钱,所以主语是sth.
而pay,spend则是人花费了多少钱,所以主语是sb.
而pay和spend一个是vi或vt,而spend是vt.
所以是 sb. pay money for sth.
sb. spend money on sth & sb. spend money in doing sth.

记住关键例句会用就可以了
I paid 20 for the book.
I offered 20 for the book.
I spent 20 on the book.
The book cost me 20.

offer 和那三个不同，offer只是报价。
