花钱在英语的三种表达方式 有关于spend cost 和pay的短语

spend：（花钱+on、花时间+in）
1、sb. spend some money on sth.
eg.I spend 1 yuan on the pen.
2、sb. spend some time in doing sth.
eg. He spends two hours in finishing his homework.
3、sb. spend some time in (doing) sth.(重点)
eg.Though I spend much time in math ,I still got "c" for it.
(误区：一般人认为表sth.的"math"前应加on，但是这里是把math前的动词省略的缘故造成的误区。判断方法：表花时间做某事用in，花钱买某物就用on，这个应该很快就能判断出来了，就不会造成误选，这是考试最常考到的，要注意啊)

cost（+to do）
1、sth. cost sb..(宾语形式) some money.(花钱买某物)
eg.This book cost me 10 dollars.
2、It cost sb.(宾语形式) some time to do sth.（花时间做某事）

pay（+for）
